Discrediting the "Model Minority" StereotypeStudy finds that while Chinese American adults are twice as likely as U.S.average to hold college degrees, Chinese Americans graduate from high school at lower rate than other youth.Complete story below. For these related stories, go to the website listed:"The Myth of the Model Minority", July 18http://www.insidehighered.com/news/2008/11/13/chineseNovember 13, 2008Discrediting the "Model Minority" StereotypeChinese Americans are not as homogeneous as they are sometimes portrayed ?br> this is particularly apparent in their college-going rates and enrollmentpatterns ?according to a new study from the Asian American Studies Programat University of Maryland at College Park and the Organization of ChineseAmericans."Some of the popular beliefs about Chinese Americans simply don"t withstandour findings, as you might expect with most stereotypes," Larry H.Shinegawa, director of the Asian American Studies Program at Maryland andco-author of the study, said in a press release.More than half ?51.7 percent ?of Chinese Americans 25 or older have earnedsome sort of college degree. This is, proportionally, nearly twice as muchas the rest of the U.S. population, 27 percent of whom have a collegedegree. In contrast, 18.5 percent of Chinese Americans have not graduatedfrom high school, compared to 15.9 percent of the general population. AmongAsian Americans, they have the second highest proportion of individualswithout a high school degree. Only Vietnamese Americans, at 27.8 percent,are less likely to graduate high school.Shinegawa said there could be any number of reasons for this disparity. Hechalks some of these figures up to generational differences among ChineseAmericans. Newer immigrants to the United States, he noted, contributegreatly to the number of individuals without high school diplomas. Moreover,he said, as immigrant families reunite, those who are more recent immigrantsmay not have the educational attainment of their relatives who immigratedearlier.Shinegawa said he expects the number of Chinese Americans with a collegedegree to decline in the future, considering the high percentage of thosewithout a high school diploma currently. Additionally, he said the collegegraduation rates for those beyond the first generation will also probablyfall as the percentages regress toward the mean of the rest of the U.S.population.The study also finds that Chinese Americans cluster at a small number ofcolleges and universities in the United States. Shinegawa said about 85percent of all Chinese Americans attend only three percent of all the highereducation institutions in the United States. While data are not availablenow on the specific institutions Chinese Americans are most likely to attend?Maryland"s Asian Studies Program plans to release a follow-up study onthis phenomenon next year ?Shinegawa said a map pinpointing theseinstitutions would have institutions almost entirely marked along thecoasts, with a few scattered throughout the rest of the country.He added that ?contributing to this phenomenon ?the children ofworking-class parents tend to attend public institutions near their homes,while children of middle-class parents tend to attend more prestigiousinstitutions that might not necessarily be near their homes.Socioeconomic status further diversifies the quality of educationalattainment. Working-class and middle-class Chinese Americans, the studyfinds, not only live in different places but send their children todifferent types of postsecondary institutions, if they do at all.Working-class Chinese Americans typically live in "ethnic enclaves" in urbanareas and are more likely to send their children to "lower-tier publiccolleges and universities." By contrast, middle-class Chinese Americans livein "suburbs and ethnoburbs" ?suburban areas with a high concentration of acertain ethnic minority ?and are more likely to send their children to"top-tier public universities and select Ivy League institutions."Lin said when looking at more prestigious institutions, first-generationChinese American are overrepresented and those within U.S.-born generationstend to be either slightly underrepresented or proportionally represented.This, he said, is probably because of "selective migration" ?the notionthat many first-generation immigrants, who have the means to immigrate, arelikely to achieve greater educational success.After Chinese Americans graduate from college, the study finds that theyearn less than non-Hispanic whites in every group of educational attainment?those who did not graduate from high school, high school graduates, thosewith some college, college graduates and advanced-degree graduates. Forexample, Chinese Americans with bachelors degrees have an average income of$55,571, while non-Hispanic Whites with the same credentials earn $62,285.The average income for those with a bachelors degree in the generalpopulation is $59,344.Additionally, Lin noted overall disparities and inequities exist for ChineseAmerican faculty members in higher education. He said Chinese Americans areoverrepresented in entry-level and pre-tenure positions ?especially whenconsidering the fields of science, technology, engineering, and mathematics?but underrepresented in tenured and administrative positions. He said thelack of Chinese American leaders and mentors in the professional world islikely to blame for the both the ethnic group"s lower average income thannon-Hispanic whites and underrepresentation in upper-level positions inhigher educationDavid Moltz

很多人，包括我自己，一旦回到和父母相处的时候，就会进入一种模式，在父母面前永远是孩子，会用孩子的方式和父母相处，如果童年和父母建立良好的关系，那回到这种模式也是爱的滋养。 如果童年和父母相处模式是在控制与抵抗控制的模式，那一旦回到童年模式，就变成了一种伤害，而且是持续伤害，我们好像一下子又变成了那个弱小的孩子，无法抵抗，无法依靠，甚至无法跟父母平等对话，体现出一味的顺从，甚至在父母面前开始僵化。 父母也许开心了，甚至很欣慰，孩子还是听自己的话，可对孩子来说，家，成了自己想要逃离的地方。 我以前一直很讨厌回家，一方面不喜欢父母的唠叨，以为自己好的名义，来控制自己按他们的方式去生活，另一方面，父母之间相处了几十年，却连他们自己的关系都处理不好，不是冷战就是吵闹，自己到家就会变成传声筒，他们彼此不沟通，却借我的嘴来传达他们之间的诉求和期望，表达的却都是希望对方如何改变，如果能一句话就改变对方，过去几十年的相处早改变了！如何摆脱这种局面？ 是时候和父母之间来一场成年人之间的对话了！需要告诉自己，我现在是成年人了，成年人之间的相处模式，彼此是平等的，相互尊重的，就如同朋友之间，我们可以表达彼此的观点，表达自己的情绪，而不是一切都听对方的！ 尊重并感谢父母，感谢父母给了自己生命，感谢将自己抚养长大，但现在，自己长大了，有能力照顾好自己，也有能力和他们平等对话了！ 汉代以前，人们都会有个成人礼，在成人礼上，作为父母，会为年满20的子女举行一场仪式，告诉他们从此以后，就是成年人了，需要承担起成年人的责任和义务！ 现在，父母可能忘了，但我们自己可以，给自己举办一次成人礼仪式，可以是一封写给父母的信，也可以是一场与父母的平等对话！ 与父母来一场成年人的对话 （点击查看千与千寻，是如何走完这段路的） 先完成如下四个步骤，处理好心情和关系，再来谈其他事情： 1. 真诚地欣赏和感激，自己欣赏的父母的优点？感恩父母为自己做了什么？ 掌握“HAPPS”感激技巧：以感恩的心态真诚表达感激-形成习惯（Habitually） -表达真诚（Authentically） -表达及时（Promptly） -表达适度（Proportionally） -表达具体（Specifically） 2. 关注共同的利益，有哪些是对方想要而且我们也希望对方得到的，一开始可能会有些难，在表达完欣赏和感激，父母情绪较好之后来谈对方的想法和期待，对我们的想法和期待。最后再来谈谈我们对父母的想法和期待，从中找到我们共同关注的部分。 关注共同利益的标准是：a.大家有交集的兴趣、利益和价值观 。b.特别是当自己的兴趣、利益和价值观与和他们发生冲突并妨碍工作时，能服从共同的部分。就父母而言，我们都希望彼此过的更好而不是更糟，从这一点出发，所有的矛盾、冲突基本都能有合作的解决方案。 3.适度地包容父母，父母的成长环境跟我们有很大的差别，他们过去的行为模式，是为适应环境，几十年的模式下来，可能根深蒂固，但这不是他们的错，我们需要理解他们的行为，他们的动机，他们的生活理念，但也要坚定的知道，理解并不意味着完全服从，对父母，我们要做的只是适度包容，跟他们分享自己的想法、自己的近况，对他们的认可，以及深度倾听，来满足他们对于“包容”的需要。 4.信守所有约定。我们跟父母之间的信任，建立在彼此是否能够达成约定，如果有被打破的承诺，信任就需要被修复，可以和父母聊一聊彼此的失信事件，并获取对方的原谅，重新建立信任。之后要信守所有约定。 修复信任的五步法： 1. 承认错误：我错了 2.说明事实：做错了什么及原因 3. 真诚道歉：对不起 4. 做出承诺：下一次我会怎么做 5.获得原谅：请问可以接受我的道歉吗？现在我们和好了吗？ （如果没有，问问对方希望我们怎么做？）

Professor: The largest animals today don"t live on land. But in the ocean where food is easier to find, a blue whale, … well, large animals can"t easily get rid of excess body heat. But for an oceangoing whale, that"s not a problem. For a 100-ton land animal, it can be. 教授说，现在体型最大的动物生活在海里，因为海里更容易觅食，而且大型动物很难甩掉身上多余的热量，但这对鲸鱼来说不成问题，对重 100 吨的陆地动物来说就是个问题了。所以教授把蓝鲸与大型陆地动物相比较是为了说明海洋环境减少了大型动物会遇到的食物和甩掉热量的问题，所以选择 D。

以下是五把通往成功的钥匙，你感受一下，仅供参考。5 Must Read Keys to Success:1. Preparation“The secret of success in life is for a man to be ready for his opportunity when it comes.”~Benjamin DisraeliSuccess loves preparation. If the perfect opportunity presented itself today, would you be ready? It"s better to be ready and not have an opportunity, then to have an opportunity and not be ready.To succeed, you must be ready when opportunity comes. Spend your time preparing for success, when your opportunity comes, you"ll be glad you did.2. Work“Success is simply a matter of luck. Ask any failure.” ~AnonymousAll failures know that success is simply a matter of luck, they know it"s just a matter of being at the right place at the right time, they know with assurance that success is directly linked to good ole fashion chance.However, those who have succeeded know that success is directly and proportionally linked to work. Even an amazing strategy can"t guarantee success. Zig Ziglar said, “The most practical, beautiful, workable philosophy in the world won"t work – if you won"t.”You have to put in the time. However, when you put in the time, it makes success all the more sweet. When you come from “behind” and do the impossible, it makes success as sweet as a honeycomb. John H. Johnson said, “I believe the greater the handicap, the greater the triumph.”3. Remember the Golden Rule“Success is still the constant application of the Golden Rule.” ~AnonymousNever forget the golden rule, “Do unto others as you would have them do unto you.” That"s the key to success. Serve your clients as you would have them serve you. Meet their needs as you would have them meet your needs. Give them prices that you would want to pay, exceed their expectations in a way that you would want your expectations to be exceeded.When you follow the golden rule, you open the door to success.4. Confidence“Confidence is the companion of success.” ~AnonymousIf you don"t believe in your abilities, don"t be surprised if no one else does either. Your negative thoughts about yourself send a signal throughout the world that others pick up on and respond accordingly. If you"re broadcasting the station “Depression 108.7” then others will treat you like you"re depressed.But, when you believe in yourself and your potential, people pick up that signal, and they will treat you according to how they believe, you believe, you should be treated. Did you get that?5. Lead“A most important key to successful leadership is your ability to direct and challenge the very best that is in those whom you lead.” ~AnonymousTo be successful you must be a great leader. There"s probably nothing more difficult than being a great leader. It"s easy to be selfish, it"s easy to only be concerned with your needs, your wants and your desires. But to succeed you have to lead! You have to do what"s best for the people; you must bring the best out of those in whom you lead.When you really lead, you will succeed.

文章的结论和总结部分是研究人员对结果的简要解释，将研究成果与引言中所述的假设或研究问题直接联系起来。通常，结论和总结的撰写用过去时态和现在时态这两种。过去时态的使用过去时可以用来表示研究的目的，简要地描述研究方法，强调研究结果并加以解释，它也可以用来描述研究的局限性。下面是一些例子，展示了在描述结论时过去时的用法。In this study, we concentrated on showing how variable ‘x" causes a change in variable ‘y".在这项研究中，我们集中展示了变量“x”如何引起变量“y”的变化。We hypothesized that the variable ‘z" will significantly impact ‘abc".我们假设变量“z”将显著影响“abc”。We extracted ‘pqr" from ‘lmn" using the protocol defined by ‘efg".我们按照“efg”给定的协议从“lmn”中提取了“pqr”。Following this study, we concluded that value of ‘x" proportionally increases as the value of ‘y" decreases. 根据这项研究，我们得出结论，“x”的值随着“y”值的减小而成比例地增加。We finally obtained a curve that depicted the dependence of ‘x" on ‘y".我们最终得到了一条曲线，描绘了“x”对“y”的依赖性。现在时的用法现在时态可以用来报告真实的发现，此外它还可以用来表达研究所支持的结论和含义。下面是一些例子，展示了现在时在描述结论时的用法。The parameter ‘abc" increased as the nutritional value of ‘xyz" was increased. These results suggest that foods higher in ‘pqr" will contribute to a greater gain in weight.随着“xyz”营养价值的增加，参数“abc”也随之增加。这些结果表明，高“pqr”含量的食物有助于增加体重。The results obtained show excellent agreement between ‘x" and ‘y".所得结果表明“x”和“y”之间有很好的一致性。通常建议使用动词形式来表示可能的影响，如“is possible”、“is likely”、“appears”、“seems”和“might”。这些动词都使用现在时态，描述研究产生的结果。一些常见的现在时结构包括“应注意（it should be noted）”、“建议（is recommended）”或“希望（it is hoped）”。将来时的用法在某些情况下，作者可能希望讨论这项工作的前景或后续实验，这时应该使用将来时态。比如以下例子：In a follow-up experiment, the authors will study ‘xyz".在后续实验中，作者将研究“xyz”。The effect of pH and temperature will be the objective of future research.pH值和温度的影响将是未来研究的目标。总而言之，作者需要根据结论部分需要传达的信息使用恰当的时态。

Jeonse tenants are taking a short position in the housing market in some sense. Jeonse involves the tenant giving the landlord a large sum of " key money " when a lease is signed. However, there is a certain level of risks of which the tenants shall be aware for leasing an apartment by Jeonse . When the apartment price goes down the amount of Jeonse deposit goes down proportionally, although this may not always be the case. Depending on the area, " jeonse " prices can range as much as 80 % of the home"s sale price. The expensive Gangnam area"s " jeonse " is about 30 % of the sales price because those properties are so expensive. As Jeonse tenants are not obpgated to pay any monthly rent, it may lead them to bepeve that Jeonse is a great deal in all aspects. As Jeonse tenants are not obpgated to pay any monthly rent, it may lead them to bepeve that Jeonse is a great deal in all aspects. It is a mon practice that Jeonse tenants have the deposit ready by taking a loan from a bank due to the sheer amount of the deposit. Since the " jeonse " price reflects the actual demand of people who reside in the area, the gap beeen rental deposits for " jeonse " and the apartment sales price means there might be an economic bubble in the apartment price. It"s difficult to see jeonse in a sentence. 用 jeonse 造句挺难的 Since the " jeonse " price reflects the actual demand of people who reside in the area, the gap beeen rental deposits for " jeonse " and the apartment sales price means there might be an economic bubble in the apartment price. This unique way of renting a house is called " jeonse "; a renter makes a lump-sum deposit on a rental space instead of paying monthly rent, at anywhere from 50 to 100 % of the market value, and gets back the whole deposit when the rent contract ends.

乔布斯斯坦福大学演讲英文原文： Stanford Report, June 14, 2005‘You"ve got to find what you love," Jobs saysThis is the text of the Commencement address by Steve Jobs, CEO of Apple Computer and of Pixar Animation Studios, delivered on June 12, 2005.I am honored to be with you today at your commencement from one of the finest universities in the world. I never graduated from college. Truth be told, this is the closest I"ve ever gotten to a college graduation. Today I want to tell you three stories from my life. That"s it. No big deal. Just three stories.The first story is about connecting the dots.I dropped out of Reed College after the first 6 months, but then stayed around as a drop-in for another 18 months or so before I really quit. So why did I drop out?It started before I was born. My biological mother was a young, unwed college graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife. Except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking: “We have an unexpected baby boy; do you want him?” They said: “Of course.” My biological mother later found out that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers. She only relented a few months later when my parents promised that I would someday go to college.And 17 years later I did go to college. But I naively chose a college that was almost as expensive as Stanford, and all of my working-class parents" savings were being spent on my college tuition. After six months, I couldn"t see the value in it. I had no idea what I wanted to do with my life and no idea how college was going to help me figure it out. And here I was spending all of the money my parents had saved their entire life. So I decided to drop out and trust that it would all work out OK. It was pretty scary at the time, but looking back it was one of the best decisions I ever made. The minute I dropped out I could stop taking the required classes that didn"t interest me, and begin dropping in on the ones that looked interesting.It wasn"t all romantic. I didn"t have a dorm room, so I slept on the floor in friends" rooms, I returned coke bottles for the 5?? deposits to buy food with, and I would walk the 7 miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it. And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on. Let me give you one example:Reed College at that time offered perhaps the best calligraphy instruction in the country. Throughout the campus every poster, every label on every drawer, was beautifully hand calligraphed. Because I had dropped out and didn"t have to take the normal classes, I decided to take a calligraphy class to learn how to do this. I learned about serif and san serif typefaces, about varying the amount of space between different letter combinations, about what makes great typography great. It was beautiful, historical, artistically subtle in a way that science can"t capture, and I found it fascinating.None of this had even a hope of any practical application in my life. But ten years later, when we were designing the first Macintosh computer, it all came back to me. And we designed it all into the Mac. It was the first computer with beautiful typography. If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts. And since Windows just copied the Mac, its likely that no personal computer would have them. If I had never dropped out, I would have never dropped in on this calligraphy class, and personal computers might not have the wonderful typography that they do. Of course it was impossible to connect the dots looking forward when I was in college. But it was very, very clear looking backwards ten years later.Again, you can"t connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something - your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life.My second story is about love and loss.I was lucky - I found what I loved to do early in life. Woz and I started Apple in my parents garage when I was 20. We worked hard, and in 10 years Apple had grown from just the two of us in a garage into a $2 billion company with over 4000 employees. We had just released our finest creation - the Macintosh - a year earlier, and I had just turned 30. And then I got fired. How can you get fired from a company you started? Well, as Apple grew we hired someone who I thought was very talented to run the company with me, and for the first year or so things went well. But then our visions of the future began to diverge and eventually we had a falling out. When we did, our Board of Directors sided with him. So at 30 I was out. And very publicly out. What had been the focus of my entire adult life was gone, and it was devastating.I really didn"t know what to do for a few months. I felt that I had let the previous generation of entrepreneurs down - that I had dropped the baton as it was being passed to me. I met with David Packard and Bob Noyce and tried to apologize for screwing up so badly. I was a very public failure, and I even thought about running away from the valley. But something slowly began to dawn on me - I still loved what I did. The turn of events at Apple had not changed that one bit. I had been rejected, but I was still in love. And so I decided to start over. I didn"t see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life.During the next five years, I started a company named NeXT, another company named Pixar, and fell in love with an amazing woman who would become my wife. Pixar went on to create the worlds first computer animated feature film, Toy Story, and is now the most successful animation studio in the world. In a remarkable turn of events, Apple bought NeXT, I retuned to Apple, and the technology we developed at NeXT is at the heart of Apple"s current renaissance. And Laurene and I have a wonderful family together.I"m pretty sure none of this would have happened if I hadn"t been fired from Apple. It was awful tasting medicine, but I guess the patient needed it. Sometimes life hits you in the head with a brick. Don"t lose faith. I"m convinced that the only thing that kept me going was that I loved what I did. You"ve got to find what you love. And that is as true for your work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven"t found it yet, keep looking. Don"t settle. As with all matters of the heart, you"ll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it. Don"t settle.My third story is about death. When I was 17, I read a quote that went something like: “If you live each day as if it was your last, someday you"ll most certainly be right.” It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself: “If today were the last day of my life, would I want to do what I am about to do today?” And whenever the answer has been “No” for too many days in a row, I know I need to change something.Remembering that I"ll be dead soon is the most important tool I"ve ever encountered to help me make the big choices in life. Because almost everything - all external expectations, all pride, all fear of embarrassment or failure - these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.About a year ago I was diagnosed with cancer. I had a scan at 7:30 in the morning, and it clearly showed a tumor on my pancreas. I didn"t even know what a pancreas was. The doctors told me this was almost certainly a type of cancer that is incurable, and that I should expect to live no longer than three to six months. My doctor advised me to go home and get my affairs in order, which is doctor"s code for prepare to die. It means to try to tell your kids everything you thought you"d have the next 10 years to tell them in just a few months. It means to make sure everything is buttoned up so that it will be as easy as possible for your family. It means to say your goodbyes. I lived with that diagnosis all day. Later that evening I had a biopsy, where they stuck an endoscope down my throat, through my stomach and into my intestines, put a needle into my pancreas and got a few cells from the tumor. I was sedated, but my wife, who was there, told me that when they viewed the cells under a microscope the doctors started crying because it turned out to be a very rare form of pancreatic cancer that is curable with surgery. I had the surgery and I"m fine now.This was the closest I"ve been to facing death, and I hope its the closest I get for a few more decades. Having lived through it, I can now say this to you with a bit more certainty than when death was a useful but purely intellectual concept:No one wants to die. Even people who want to go to heaven don"t want to die to get there. And yet death is the destination we all share. No one has ever escaped it. And that is as it should be, because Death is very likely the single best invention of Life. It is Life"s change agent. It clears out the old to make way for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away. Sorry to be so dramatic, but it is quite true.Your time is limited, so don"t waste it living someone else"s life. Don"t be trapped by dogma - which is living with the results of other people"s thinking. Don"t let the noise of other"s opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary. When I was young, there was an amazing publication called The Whole Earth Catalog, which was one of the bibles of my generation. It was created by a fellow named Stewart Brand not far from here in Menlo Park, and he brought it to life with his poetic touch. This was in the late 1960"s, before personal computers and desktop publishing, so it was all made with typewriters, scissors, and polaroid cameras. It was sort of like Google in paperback form, 35 years before Google came along: it was idealistic, and overflowing with neat tools and great notions.Stewart and his team put out several issues of The Whole Earth Catalog, and then when it had run its course, they put out a final issue. It was the mid-1970s, and I was your age. On the back cover of their final issue was a photograph of an early morning country road, the kind you might find yourself hitchhiking on if you were so adventurous. Beneath it were the words: “Stay Hungry. Stay Foolish.” It was their farewell message as they signed off. Stay Hungry. Stay Foolish. And I have always wished that for myself. And now, as you graduate to begin anew, I wish that for you.Stay Hungry. Stay Foolish.Thank you all very much.

Remembering that I"ll be dead soon is the most important tool I"ve ever encountered to help me make the big choices in life.

In summary, it seems impossible that for every person that is subjected to media scrutiny, his or her reputation will eventually be diminished. Millions of people are mentioned in the media every day yet still manage to go about their lives unhurt by the media. Normal individuals that are subjected to media scrutiny can have their reputation either enhanced or damaged depending on the circumstances surrounding the media coverage. The likelihood of a diminished reputation from the media rises proportionally with the level of notoriety that an individual possesses and the outrageousness of that person"s behavior. The length of time in the spotlight can also be a determining factor, as the longer the person is examined in the media, the greater the possibility that damaging information will be discovered or that the individual will do something to disparage his or her reputation. But to broadly state that media scrutiny will diminish anyone"s reputation is to overstate the distinct possibility that, given a long enough time and a certain level of intensity of coverage, the media may damage a person"s reputation.

The issue of the Yellow River has become the biggest concern of members of the Chinese peoples Political Consultative Conference. My childhood, in fact, is closely associated with the river. My father is an engineering geologist, and he used to take me with him on his trips to the hydropower stations on the river. I enjoyed those trips, especially the trip to Longyang Xia reservoir. Although ten years have passed since my visit, I can still recall the scenery; I can still recall the water I saw at the reservoir. It was pure, clean and blue, not like the water I saw in the middle reaches of the river, which had turned brown and muddy after passing through the Loess Plateau. 　　Once during our stay at the power station, we were caught in a thunderstorm. And when rain stopped, I could see trickles of water rolling down mountain slopes and flowing into the reservoir. It carried little mud or sand, because at that time, trees and grass still grew around the reservoir. And they protected the soil. At Longyang Xia I was struck by the beauty of nature, and as a child I wanted to stay there and to grow up with our Yellow River. 　　Li Bai, the Tang Dynasty poet, said praises to the flowing water in the Yellow River. He saw it as coming down from heaven and nurturing the people along her way to the sea. However, in 1997,for 330days, not a single drop of water from the Yellow River went into the sea. And droughts are not the only punishment by nature. A friend of my father"s, a university professor, is doing research on the Yellow River. According to this professor, the Yellow River will soon change its course if we allow this situation to continue. Because there is no longer enough water to carry away the silt and mud in the lower reaches of the river and the riverbed rises higher and higher each year. 　　We have taken too much from nature, but given back too little in return. And this is the cost of the unbalanced growth. If we had taken care of the vegetation in the upper and middle reaches of the Yellow River, we would still experience the river as Li Bai described it. 　　While the developed countries are consuming proportionally more natural resources than the rest of the world, they"ve also taken some good measures in protecting nature. And as a developing country, China can learn from them in this aspect. 　　Last year, when I was visiting Australia with a group of Chinese students who had won prizes in an English Skills Test, our Australian hosts invited us to join them for a horse-ride in the mountains. After two hours on horseback, we reached a valley, where there was a most beautiful meadow, with flowers in all colors dotted on a huge blanket of green. When I began to praise the beauty of nature, my friends told me that in this valley, there used to be a big mine and the wastewater from the mine turned everything brown. When the mine was abandoned, people made great efforts to restore the green vegetation. They also used the latest biological technology choosing the best grass seeds suitable for the local soil. So the beautiful meadow is a result of commitment, hard work, and new technology. 　　What happened to this valley in Australia should also happen to our Yellow River and, in fact, it is happening. I have seen farmers planting trees on mountains along the Yellow River. I have seen them climb the mountain tops with seedlings on their shoulders because they had no machinery. I have seen them pour on trees the water they had carried up in buckets from miles down the valley. These farmers are quietly nourishing our Yellow River, just as the river has nourished them. 　　And these farmers, men and women I don"t know, gave me the confidence that we and our Yellow River will grow together, and someday in the future, we will be able to drink the clean water from our Yellow River again, because she is our dearest mother. 　　Thank you 【篇二】大学生励志英语演讲稿 　　Today"s speech I want to talk to my classmates about a few stories, these stories are in our side, but we have never noticed, thinking. 　　One night last semester, go alone to five teaching self - study. Fatigue to his eyes faint, faint yellow light trance to see a little boy shuttle between tables and chairs, those hands links to pick up the garbage in the table bucket. Looking back, his mother is holding a large woven bag, came and took the garbage. Mother and son of the shadow under the irradiation of a group of lights appear very long, repeated, fade out of the classroom. I just looked at, what seems to be thinking, so for a long time. 　　A small thing in life study, let me look at yourself again. His little bad habits, bring others? Shouldn"t we be good young people who love school and life? How can we indulge in the erosion of negative energy on us? I have asked a few students, how don"t you remember to take away the garbage generated by self-study in class? Most students are vacant answer, not someone to accept? 　　Some of our own little habits, little laziness. Slowly become entrenched negative energy, we didn"t even notice, slowly accustomed to. Our youth, we are young, but ignorance is not synonymous with youth and youth. 　　Classmate, don"t know if you have ever met this kind of situation, one night, you are going to carry a bag to the library to study, is shouting to let the dormitory of several other elder brothers go with you, at that time, a classmate said: " oh, boy, the sun came out to the west, you should go to the library, don"t pack! " you hesitated, thinking about next week"s exam, or thinking about to go to the library self-study make-up class, so, you are going to go, then another voice rang:" hurry up to open the computer, hero league open a black shop sent a person ah, how can you do without! " at this time, you silently put down the bag, opened the computer, just study the idea of abrupt was left behind ... 　　The word " positive energy" students are familiar with, its network meaning refers to all give people up, give people hope and pursuit, make people action motivation and feelings. As a contemporary college student, I think we should be a positive energy person, at the same time, also should make friends with positive energy, in each other"s communication, let positive energy together into a larger upward force, so that college life more positive. " true, good, beautiful" has always been as a synonym for positive energy, specific to college life, positive energy also covers a lot of meaning: for example, pay attention to social welfare undertakings, to participate in social practice, let love transfer, so that their lives are sublimated; In the face of setbacks and life is not the best, to be able to persevere, with a positive attitude to face; In the study, be able to persevere, hard work, perseverance; Be a responsible person, able to understand their responsibilities, parents" expectations and social expectations. My classmates, my story is not over yet. 【篇三】大学生励志英语演讲稿 　　We, leaving ignorance ushered in our youth. Youth, let us unbridled, relaxed, appreciate the wind that freedom, feel the cloud that comfortable, because youth gives us the peak of life, we do not need to mature, we are no longer ignorant, we only persistent. Positive energy in youth. Strong energy helps me to support a firm belief, so that I am full of confidence in a challenging tomorrow. 　　Life is the pursuit of ideal, ideal is the indicator of life, lost the role of the lamp, will lose the courage of life. Therefore, only by adhering to the lofty ideals of life, will not be lost in the sea of life. Tolstoy will be the ideal of life is divided into a lifetime of ideal, the ideal of a stage, the ideal of a year, the ideal of a month, even the ideal of a day, an hour, a minute. When you hear this, students, do you think of your ideal? 　　Whose youth is not sad? Whose youth never want to give up? Who"s youth without setbacks and difficulties? But, I no longer fear, I know there will be a kind of positive energy in my side, like hot sunshine warm my heart, take me to a better tomorrow. And I, will also become the positive energy of others, do my best to encourage and warm like I once helpless people. 　　The flower season of life is the spring of life, it is beautiful, but short. As a college student should be in this period, study hard, work hard, find a piece of their own sky. Youth is the hope of the motherland, the future of the nation. Everyone governs his own tomorrow. 　　One philosopher said, " the dream has gone many ways, wake up or in bed. " it vividly tells us a truth: people can"t lie in the dream of ideal life. Yes, people not only want to have an ideal, but also bold fantasy, but also want to work hard to do, lying in the ideal waiting for a new start, if not only in the distant future, even have will lose. Students, are you also wandering in the dream of ideal? 　　Predecessors said well, " aspiring people set long ambition, no ambition people often aspire to", those who have no ambition " ambition", is a dream, is the so-called " ideal", they put their blueprint structure painted again beautiful, perfect, also is just a castle in the air, mirage. Students, are you a man of long ambition, or often determined? In the green years, whenever I am sad and confused, wandering helpless, there are always some people or things to encourage me, sending out a positive light warm me. 　　Be a person with positive energy, let oneself have the power to move forward. Positive energy is a powerful energy, it is bound to include a positive driving force, only in this way can make your studies, career, quality of life, etc. progress. No power is a terrible thing, just like a car without gasoline, rockets without fuel, plants no longer absorb sunlight, you will only chaos to every day, do the same thing, to this point naturally do what to do, there is no big goal and ideal. Isn"t this terrible enough? Are you willing to silence like a pool of stagnant water standing still, also don"t want to more power to meet the daily sun add energy? Of course not. when you have positive energy, you will naturally take your steps and be motivated to move to a new starting point.

Transcript of Commencement Speech at Stanford given by Steve JobsSlashDot ^ | 6/14/2005 | Steve JobsThank you. I"m honored to be with you today for your commencement from one of the finest universities in the world. Truth be told, I never graduated from college and this is the closest I"ve ever gotten to a college graduation. Today I want to tell you three stories from my life. That"s it. No big deal. Just three stories. The first story is about connecting the dots. I dropped out of Reed College after the first six months but then stayed around as a drop-in for another eighteen months or so before I really quit. So why did I drop out? It started before I was born. My biological mother was a young, unwed graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife, except that when I popped out, they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking, "We"ve got an unexpected baby boy. Do you want him?" They said, "Of course." My biological mother found out later that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers. She only relented a few months later when my parents promised that I would go to college. This was the start in my life. And seventeen years later, I did go to college, but I na07vely chose a college that was almost as expensive as Stanford, and all of my working-class parents" savings were being spent on my college tuition. After six months, I couldn"t see the value in it. I had no idea what I wanted to do with my life, and no idea of how college was going to help me figure it out, and here I was, spending all the money my parents had saved their entire life. So I decided to drop out and trust that it would all work out OK. It was pretty scary at the time, but looking back, it was one of the best decisions I ever made. The minute I dropped out, I could stop taking the required classes that didn"t interest me and begin dropping in on the ones that looked far more interesting. It wasn"t all romantic. I didn"t have a dorm room, so I slept on the floor in friends" rooms. I returned Coke bottles for the five-cent deposits to buy food with, and I would walk the seven miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it. And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on. Let me give you one example. Reed College at that time offered perhaps the best calligraphy instruction in the country. Throughout the campus every poster, every label on every drawer was beautifully hand-calligraphed. Because I had dropped out and didn"t have to take the normal classes, I decided to take a calligraphy class to learn how to do this. I learned about serif and sans-serif typefaces, about varying the amount of space between different letter combinations, about what makes great typography great. It was beautiful, historical, artistically subtle in a way that science can"t capture, and I found it fascinating. None of this had even a hope of any practical application in my life. But ten years later when we were designing the first Macintosh computer, it all came back to me, and we designed it all into the Mac. It was the first computer with beautiful typography. If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts, and since Windows just copied the Mac, it"s likely that no personal computer would have them. If I had never dropped out, I would have never dropped in on that calligraphy class and personals computers might not have the wonderful typography that they do. Of course it was impossible to connect the dots looking forward when I was in college, but it was very, very clear looking backwards 10 years later. Again, you can"t connect the dots looking forward. You can only connect them looking backwards, so you have to trust that the dots will somehow connect in your future. You have to trust in something--your gut, destiny, life, karma, whatever--because believing that the dots will connect down the road will give you the confidence to follow your heart, even when it leads you off the well-worn path, and that will make all the difference.

If you live each day as if it was your last, someday you"ll most certainly be right. This is the text of the Commencement address by Steve Jobs, CEO of Apple Computer and of Pixar Animation Studios, delivered on June 12, 2005. I am honored to be with you today at your commencement from one of the finest universities in the world. I never graduated from college. Truth be told, this is the closest I"ve ever gotten to a college graduation. Today I want to tell you three stories from my life. That"s it. No big deal. Just three stories. The first story is about connecting the dots. I dropped out of Reed College after the first 6 months, but then stayed around as a drop-in for another 18 months or so before I really quit. So why did I drop out? It started before I was born. My biological mother was a young, unwed college graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife. Except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking: "We have an unexpected baby boy; do you want him?" They said: "Of course." My biological mother later found out that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers. She only relented a few months later when my parents promised that I would someday go to college. And 17 years later I did go to college. But I naively chose a college that was almost as expensive as Stanford, and all of my working-class parents" savings were being spent on my college tuition. After six months, I couldn"t see the value in it. I had no idea what I wanted to do with my life and no idea how college was going to help me figure it out. And here I was spending all of the money my parents had saved their entire life. So I decided to drop out and trust that it would all work out OK. It was pretty scary at the time, but looking back it was one of the best decisions I ever made. The minute I dropped out I could stop taking the required classes that didn"t interest me, and begin dropping in on the ones that looked interesting. It wasn"t all romantic. I didn"t have a dorm room, so I slept on the floor in friends" rooms, I returned coke bottles for the 5?? deposits to buy food with, and I would walk the 7 miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it. And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on. Let me give you one example: Reed College at that time offered perhaps the best calligraphy instruction in the country. Throughout the campus every poster, every label on every drawer, was beautifully hand calligraphed. Because I had dropped out and didn"t have to take the normal classes, I decided to take a calligraphy class to learn how to do this. I learned about serif and san serif typefaces, about varying the amount of space between different letter combinations, about what makes great typography great. It was beautiful, historical, artistically subtle in a way that science can"t capture, and I found it fascinating. None of this had even a hope of any practical application in my life. But ten years later, when we were designing the first Macintosh computer, it all came back to me. And we designed it all into the Mac. It was the first computer with beautiful typography. If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts. And since Windows just copied the Mac, its likely that no personal computer would have them. If I had never dropped out, I would have never dropped in on this calligraphy class, and personal computers might not have the wonderful typography that they do. Of course it was impossible to connect the dots looking forward when I was in college. But it was very, very clear looking backwards ten years later. Again, you can"t connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something — your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life. My second story is about love and loss. I was lucky — I found what I loved to do early in life. Woz and I started Apple in my parents garage when I was 20. We worked hard, and in 10 years Apple had grown from just the two of us in a garage into a $2 billion company with over 4000 employees. We had just released our finest creation — the Macintosh — a year earlier, and I had just turned 30. And then I got fired. How can you get fired from a company you started? Well, as Apple grew we hired someone who I thought was very talented to run the company with me, and for the first year or so things went well. But then our visions of the future began to diverge and eventually we had a falling out. When we did, our Board of Directors sided with him. So at 30 I was out. And very publicly out. What had been the focus of my entire adult life was gone, and it was devastating. I really didn"t know what to do for a few months. I felt that I had let the previous generation of entrepreneurs down - that I had dropped the baton as it was being passed to me. I met with David Packard and Bob Noyce and tried to apologize for screwing up so badly. I was a very public failure, and I even thought about running away from the valley. But something slowly began to dawn on me — I still loved what I did. The turn of events at Apple had not changed that one bit. I had been rejected, but I was still in love. And so I decided to start over. I didn"t see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life. During the next five years, I started a company named NeXT, another company named Pixar, and fell in love with an amazing woman who would become my wife. Pixar went on to create the worlds first computer animated feature film, Toy Story, and is now the most successful animation studio in the world. In a remarkable turn of events, Apple bought NeXT, I returned to Apple, and the technology we developed at NeXT is at the heart of Apple"s current renaissance. And Laurene and I have a wonderful family together.

　　是不是马上要上英语课了，要作英语的即兴演讲呢？下面是我为你整理的几篇，希望能帮到你哟。 　　篇一 　　Good afternoon, ladies and gentlemen. The issue of the Yellow River has bee the biggest concern of members of the Chinese peoples Political Consultative Conference. My childhood, in fact, is closely associated with the river. My father is an engineering geologist, and he used to take me with him on his trips to the hydropower stations on the river. I enjoyed those trips, especially the trip to Longyang Xia reservoir. Although ten years have passed since my visit, I can still recall the scenery; I can still recall the water I saw at the reservoir. It was pure, clean and blue, not like the water I saw in the middle reaches of the river, which had turned brown and muddy after passing through the Loess Plateau. 　　Once during our stay at the power station, we were caught in a thunderstorm. And when rain stopped, I could see trickles of water rolling down mountain slopes and flowing into the reservoir. It carried little mud or sand, because at that time, trees and grass still grew around the reservoir. And they protected the soil. At Longyang Xia I was struck by the beauty of nature, and as a child I wanted to stay there and to grow up with our Yellow River. 　　Li Bai, the Tang Dynasty poet, said praises to the flowing water in the Yellow River. He saw it as ing down from heaven and nurturing the people along her way to the sea. However, in 1997,for 330days, not a single drop of water from the Yellow River went into the sea. And droughts are not the only punishment by nature. A friend of my father"s, a university professor, is doing research on the Yellow River. According to this professor, the Yellow River will soon change its course if we allow this situation to continue. Because there is no longer enough water to carry away the silt and mud in the lower reaches of the river and the riverbed rises higher and higher each year. 　　We have taken too much from nature, but given back too little in return. And this is the cost of the unbalanced growth. If we had taken care of the vegetation in the upper and middle reaches of the Yellow River, we would still experience the river as Li Bai described it. 　　While the developed countries are consuming proportionally more natural resources than the rest of the world, they"ve also taken some good measures in protecting nature. And as a developing country, China can learn from them in this aspect. 　　Last year, when I was visiting Australia with a group of Chinese students who had won prizes in an English Skills Test, our Australian hosts invited us to join them for a horse-ride in the mountains. After two hours on horseback, we reached a valley, where there was a most beautiful meadow, with flowers in all colors dotted on a huge blanket of green. When I began to praise the beauty of nature, my friends told me that in this valley, there used to be a big mine and the wastewater from the mine turned everything brown. When the mine was abandoned, people made great efforts to restore the green vegetation. They also used the latest biological technology choosing the best grass seeds suitable for the local soil. So the beautiful meadow is a result of mitment, hard work, and new technology. 　　What happened to this valley in Australia should also happen to our Yellow River and, in fact, it is happening. I have seen farmers planting trees on mountains along the Yellow River. I have seen them climb the mountain tops with seedlings on their shoulders because they had no machinery. I have seen them pour on trees the water they had carried up in buckets from miles down the valley. These farmers are quietly nourishing our Yellow River, just as the river has nourished them. 　　And these farmers, men and women I don"t know, gave me the confidence that we and our Yellow River will grow together, and someday in the future, we will be able to drink the clean water from our Yellow River again, because she is our dearest mother. 　　Thank you. 　　篇二 　　Dream 　　Hi everybody. 　　I am so glad to give my speech to you here.Now I will start my topic about The Dream English,as you know ,The Dream English plans to put our dream e true。When I was a little boy ,I was so curious about english as long as I heard someone speak english around me,so I am very interested in english.Thank for The Dream English,I have a chance to learn more about english which is about life and study. In my opinion,english is not only a language but also a study.It contains much useful knowledge and life experience,if we all try our best to learn about it,such as its background and its history,we can regard it as a tool to make contribution to ourselves and our country. 　　That"s all my speech,thank you. 　　篇三 　　I have nothing to offer but blood, toil, tears and sweat. We have before us an ordeal of the most grievous kind. We have before us many, many months of struggle and suffering. You ask, what is our aim? I can answer in one word, it is victory. Victory at all costs—victory in spite of all terrors—victory, however long and hard the road may be, for without victory there is no survival. Let that be realized, no survival for the British Empire, no survival for all that British Empire has stood for , no survival for the urge, the impulse of the ages, that mankind shall more forward toward his goal. I take up my task in buoyancy and hope. I feel sure that our cause will not be suffered to fail among men. I feel entitled at this juncture, at this time, to claim the aid of all and to say, “e then, let us go forward together with our united strength.”

我有一个梦想今天，我高兴的同大家一起参加这次将成为我国历史上为争取自由而举行的最伟大的示威集会。 100年前，一位伟大的美国人签署了解放黑奴宣言，今天我们就是在他的雕像前集会。这一庄严宣言犹如灯塔的光芒，给千百万在那摧残生命的不义之火中饱受煎熬的黑奴带来了希望。它之到来犹如欢乐的黎明，结束了束缚黑人的漫漫长夜。然而100年后的今天，我们必须正视黑人还没有得到自由这一悲惨的事实。100年后的今天，在种族隔离的镣铐和种族歧视的枷锁下，黑人的生活备受压榨。100年后的今天，黑人仍生活在物质充裕的海洋中一个穷困的孤岛上。100年后的今天，黑人仍然萎缩在美国社会的角落里，并且意识到自己是故土家园中的流亡者。今天我们在这里集会，就是要把这种骇人听闻的情况公诸于世。就某种意义而言，今天我们是为了要求兑现诺言而汇集到我们国家的首都来的。我们共和国的缔造者草拟宪法和独立宣言的气壮山河的词句时，曾向每一个美国人许下了诺言，他们承诺给予所有的人以生存、自由和追求幸福的不可剥夺的权利。就有色公民而论，美国显然没有实践她的诺言。美国没有履行这项神圣的义务，只是给黑人开了一张空头支票，支票上盖着“资金不足”的戳子后便退了回来。但是我们不相信正义的银行已经破产，我们不相信，在这个国家巨大的机会之库里已没有足够的储备。因此今天我们要求将支票兑现——这张支票将给予我们宝贵的自由和正义保障。我们来到这个圣地也是为了提醒美国，现在是非常急迫的时刻。现在决非侈谈冷静下来或服用渐进主义的镇静剂的时候。现在是实现民主的诺言时候。现在是从种族隔离的荒凉阴暗的深谷攀登种族平等的光明大道的时候，现在是向上帝所有的儿女开放机会之门的时候，现在是把我们的国家从种族不平等的流沙中拯救出来，置于兄弟情谊的磐石上的时候。如果美国忽视时间的迫切性和低估黑人的决心，那么，这对美国来说，将是致命伤。自由和平等的爽朗秋天如不到来，黑人义愤填膺的酷暑就不会过去。1963年并不意味着斗争的结束，而是开始。有人希望，黑人只要撒撒气就会满足；如果国家安之若素，毫无反应，这些人必会大失所望的。黑人得不到公民的基本权利，美国就不可能有安宁或平静，正义的光明的一天不到来，叛乱的旋风就将继续动摇这个国家的基础。但是对于等候在正义之宫门口的心急如焚的人们，有些话我是必须说的。在争取合法地位的过程中，我们不要采取错误的做法。我们不要为了满足对自由的渴望而抱着敌对和仇恨之杯痛饮。我们斗争时必须永远举止得体，纪律严明。我们不能容许我们的具有崭新内容的抗议蜕变为暴力行动。我们要不断地升华到以精神力量对付物质力量的崇高境界中去。现在黑人社会充满着了不起的新的战斗精神，但是不能因此而不信任所有的白人。因为我们的许多白人兄弟已经认识到，他们的命运与我们的命运是紧密相连的，他们今天参加游行集会就是明证。他们的自由与我们的自由是息息相关的。我们不能单独行动。当我们行动时，我们必须保证向前进。我们不能倒退。现在有人问热心民权运动的人，“你们什么时候才能满足？”只要黑人仍然遭受警察难以形容的野蛮迫害，我们就绝不会满足。只要我们在外奔波而疲乏的身躯不能在公路旁的汽车旅馆和城里的旅馆找到住宿之所，我们就绝不会满足。只要黑人的基本活动范围只是从少数民族聚居的小贫民区转移到大贫民区，我们就绝不会满足。只要我们的孩子被“仅限白人”的标语剥夺自我和尊严，我们就绝不会满足。只要密西西比州仍然有一个黑人不能参加选举，只要纽约有一个黑人认为他投票无济于事，我们就绝不会满足。不！我们现在并不满足，我们将来也不满足，除非正义和公正犹如江海之波涛，汹涌澎湃，滚滚而来。我并非没有注意到，参加今天集会的人中，有些受尽苦难和折磨，有些刚刚走出窄小的牢房，有些由于寻求自由，曾在居住地惨遭疯狂迫害的打击，并在警察暴行的旋风中摇摇欲坠。你们是人为痛苦的长期受难者。坚持下去吧，要坚决相信，忍受不应得的痛苦是一种赎罪。让我们回到密西西比去，回到亚拉巴马去，回到南卡罗来纳去，回到佐治亚去，回到路易斯安那去，回到我们北方城市中的贫民区和少数民族居住区去，要心中有数，这种状况是能够也必将改变的。我们不要陷入绝望而不可自拔。朋友们，今天我对你们说，在此时此刻，我们虽然遭受种种困难和挫折，我仍然有一个梦想，这个梦想深深扎根于美国的梦想之中。我梦想有一天，这个国家会站立起来，真正实现其信条的真谛：“我们认为真理是不言而喻，人人生而平等。”我梦想有一天，在佐治亚的红山上，昔日奴隶的儿子将能够和昔日奴隶主的儿子坐在一起，共叙兄弟情谊。我梦想有一天，甚至连密西西比州这个正义匿迹，压迫成风，如同沙漠般的地方，也将变成自由和正义的绿洲。我梦想有一天，我的四个孩子将一个不是以他们的肤色，而是以他们的品格优劣来评价他们的国度里生活。今天，我有一个梦想。我梦想有一天，亚拉巴马州能够有所转变，尽管该州州长现在仍然满口异议，反对联邦法令，但有朝一日，那里的黑人男孩和女孩将能与白人男孩和女孩情同骨肉，携手并进。今天，我有一个梦想。我梦想有一天，幽谷上升，高山下降；坎坷曲折之路成坦途，圣光披露，满照人间。这就是我们的希望。我怀着这种信念回到南方。有了这个信念，我们将能从绝望之岭劈出一块希望之石。有了这个信念，我们将能把这个国家刺耳的争吵声，改变成为一支洋溢手足之情的优美交响曲。有了这个信念，我们将能一起工作，一起祈祷，一起斗争，一起坐牢，一起维护自由；因为我们知道，终有一天，我们是会自由的。在自由到来的那一天，上帝的所有儿女们将以新的含义高唱这支歌：“我的祖国，美丽的自由之乡，我为您歌唱。您是父辈逝去的地方，您是最初移民的骄傲，让自由之声响彻每个山岗。”如果美国要成为一个伟大的国家，这个梦想必须实现！让自由之声从新罕布什尔州的巍峨的崇山峻岭响起来！让自由之声从纽约州的崇山峻岭响起来！让自由之声从宾夕法尼亚州的阿勒格尼山响起来！让自由之声从科罗拉多州冰雪覆盖的落基山响起来！让自由之声从加利福尼亚州蜿蜒的群峰响起来！不仅如此，还要让自由之声从佐治亚州的石岭响起来！让自由之声从田纳西州的了望山响起来！让自由之声从密西西比的每一座丘陵响起来！让自由之声从每一片山坡响起来！当我们让自由之声响起，让自由之声从每一个大小村庄、每一个州和每一个城市响起来时，我们将能够加速这一天的到来，那时，上帝的所有儿女，黑人和白人，犹太教徒和非犹太教徒，耶稣教徒和天主教徒，都将手携手，合唱一首古老的黑人灵歌：“自由啦！自由啦！感谢全能上帝，我们终于自由啦！”

In summary, it seems impossible that for every person that is subjected to media scrutiny, his or her reputation will eventually be diminished. Millions of people are mentioned in the media every day yet still manage to go about their lives unhurt by the media. Normal individuals that are subjected to media scrutiny can have their reputation either enhanced or damaged depending on the circumstances surrounding the media coverage. The likelihood of a diminished reputation from the media rises proportionally with the level of notoriety that an individual possesses and the outrageousness of that person"s behavior. The length of time in the spotlight can also be a determining factor, as the longer the person is examined in the media, the greater the possibility that damaging information

维基英文百科不就行了，搜steve jobs不就有了，不过估计详细过头了 Steven Paul "Steve" Jobs (February 24, 1955 – October 5, 2011)[5] was an American inventor and businessman. He was co-founder, chairman, and chief executive officer of Apple Inc.[6] Jobs also previously served as chief executive of Pixar Animation Studios; he became a member of the board of directors of the Walt Disney Company in 2006, following the acquisition of Pixar by Disney.In the late 1970s, Jobs—along with Apple co-founder Steve Wozniak, Mike Markkula and others—designed, developed, and marketed one of the first commercially successful lines of personal computers, the Apple II series. In the early 1980s, Jobs was among the first to see the commercial potential of Xerox PARC"s mouse-driven graphical user interface, which led to the creation of the Macintosh.[7][8] After losing a power struggle with the board of directors in 1985, Jobs resigned from Apple and founded NeXT, a computer platform development company specializing in the higher-education and business markets. Apple"s subsequent 1996 buyout of NeXT brought Jobs back to the company he co-founded, and he served as its interim CEO from 1997, then becoming permanent CEO from 2000 onwards.[9] After resigning as CEO in August 2011, Jobs was elected chairman of Apple"s board of directors and held that title until his death.In 1986, he acquired the computer graphics division of Lucasfilm Ltd, which was spun off as Pixar Animation Studios.[10] He was credited in Toy Story (1995) as an executive producer.[11] He remained CEO and majority shareholder at 50.1 percent until its acquisition by The Walt Disney Company in 2006.[12] Consequently Jobs became Disney"s largest individual shareholder at 7 percent and a member of Disney"s Board of Directors.[13][14]On October 5, 2011, Jobs died in California at age 56, seven years after being diagnosed with pancreatic cancer.[15]这是简介

天王星是太阳系中离太阳第七远行星，从直径来看，是太阳系中第三大行星。天王星的体积比海王星大，质量却比其小。 由于冥王星太暗太小，发现后很长时间不能确定它的大小。最早估计它的直径是6600千米，1949年改为10000千米。1950年，柯伊伯用新建的5米望远镜将其修正为6000千米，1965年又用冥王星掩暗星的方法定出直径的上限为5500千米。1977年发现冥王星表面是冰冻的甲烷，按其反照率测算，冥王星的直径缩小到2700米。1980年用夏威夷莫纳克亚山上的3.6米红外望远镜测出的冥王星直径在2600～4000千米之间，查龙直径为2000千米。近年一些天文学家观测指出，冥王星的直径约为2400千米，比月球(3475千米)还小，而查龙直径为1180千米，它与冥王星直径之比是2:1，是九大行星中行星与卫星直径之比最大的。所以，有人说冥王星和它的卫星更像一个双行星系统。 天王星的组成 天王星基本上是由岩石和各种各样的冰组成的，它仅含有15％的氢和一些氦（与大都由氢组成的木星和土星相比是较少的）。天王星和海王星在许多方面与木星和土星在去掉巨大液态金属氢外壳后的内核很相象。虽然天王星的内核不像木星和土星那样是由岩石组成的，但它们的物质分布却几乎是相同的。 天王星的大气层含有大约83％的氢，15％的氦和2％的甲烷。 如其他所有的气态行星一样，天王星也有带状的云围绕着它快速飘动。但是它们太微弱了，以至只能由旅行者2号经过加工的图片才可看出（右图）。最近由哈博望远镜的观察（左图）显示的条纹却更大更明显。据推测，这种差别主要是由于季节的作用而产生的（太阳直射到天王星的某个低纬地区可能造成明显的白天黑夜的作用）。 天王星的颜色 天王星显蓝色是其外层大气层中的甲烷吸收了红光的结果。那儿或许有像木星那样的彩带，但它们被覆盖着的甲烷层遮住了。 像其他所有气态行星一样，天王星有光环。它们像木星的光环一样暗，但又像土星的光环那样由相当大的直径达到10米的粒子和细小的尘土组成。天王星有11层已知的光环，但都非常暗淡；最亮的那个被称为Epsilon光环。天王星的光环是继土星的被发现后第一个被发现的，这一发现被认为是十分重要的，由此我们知道了光环是行星的一个普遍特征，而不是仅为土星所特有的。 旅行者2号发现了继已知的5颗大卫星后的10颗小卫星。看来在光环内还有一些更小的卫星。 天王星基本上是由岩石和各种各样的冰组成的，它仅含有15％的氢和一些氦（与大都由氢组成的木星和土星相比是较少的）。天王星和海王星在许多方面与木星和土星在去掉巨大液态金属氢外壳后的内核很相象。虽然天王星的内核不像木星和土星那样是由岩石组成的，但它们的物质分布却几乎是相同的。

目前只有火狐浏览器支持FLASH插件。下载火狐浏览器的步骤：1、flashfox这款浏览器，分别有有安卓、IOS版，你可以去应用商店下载。如果要下载，为了安全，请到手机自带的APP市场去下载。电脑网站上的下载链接质量参差不齐，还容易中病毒，并且会携带很多绑定软件，还有很多广告，是比较烦恼的，如不专业最好不要尝试。2、打开手机应用市场，输入“flashfox”，点击搜索。搜索结果出来后，会有很多相似功能的软件，但是一定要选对，如图所示。3、下载完成后，会自动安装到手机上。它只是一款手机浏览器，除了比手机自带浏览器多flash功能外，和其它手机自带浏览器和其它第三方浏览器没有任何区别。下图是安装成功后的页面。4、浏览器安装完成了，可以输入你的页游网址，并登陆。测试一下，是不是已经可以象在网页上操作一样。5、一般需要FLASH插件的，都是玩手游的，这就要求手机配置了，配置低的就不要尝试了，否则手机会很卡。扩展资料中文名：Flash功能功能：在手机上观看Flash动画娱乐性：进行Flash游戏简称：音乐闪卡（MFlash）Flash功能指的是可以在手机上观看Flash动画，进行Flash游戏等功能。随着手机技术的发展和娱乐性的增加，Flash功能已经成为手机发展的新方向之一。Flash技术最早兴起在家用电脑上，由于当时的手机功能比较单一，而且从屏幕颜色、处理器速度、压缩技术等方面都不能实现手机对Flash的支持。Flash技术最早兴起在家用电脑上，由于当时的手机功能比较单一，而且从屏幕颜色、处理器速度、压缩技术等方面都不能实现手机对Flash的支持。 随着手机技术和Flash技术的进步，这种可能终于成为了现实。事实上手机和掌上电脑的分界已越来越不明显，必须为每一款手机设计一个不同的界面，因为它们的屏幕大小各有不同。当然你的内核可能是相同的，而且还要注意的是各类手机的CPU的计算能力和内存的大小，这无疑是些很苛刻的要求。事实上，Flash进入手机后，对手机游戏的开发也将带来革命性的变化，由于Flash Player 7将运行时的性能提高到了原来的2至5倍，因此可以提供大量中、小型游戏的开发，这也使受限于CPU能力的手机提供丰富的游戏成为可能。在国内，已经有软件厂商致力于手机播放Flash的工作，可以把Flash移植到支持K-JAVA的彩屏手机中运行，简称：音乐闪卡（MFlash）。该音乐闪卡支持矢量、声音、交互、游戏，效果很好。可应用于移动百宝箱业务，弥补百宝箱的内容空缺。参考资料百度百科-Flash功能

usedtodosth.意思是“过去常常做某事”，表示过去经常做或一直做而现在不做，它只用于过去时态。　　(一)肯定句式：　　主语+usedto+动词原形……　　例如：Iusedtogotothecinema,butIneverhavetimenow.我过去经常去看电影，但现在没有时间了。　　Heusedtolistentopopmusicbutnowhelikesrockmusic.他过去总听流行音乐，但现在喜欢摇滚了。　　(二)否定句式：　　A)主语+didnotuseto+动词原形……　　B)主语+usednotto+动词原形……　　第一种否定句型，就是把used当做实义动词来看，所以变否定句要用助动词did;第二种否定句是把used当做情态动词，变否定句直接在used后面加not即可，usednot可以缩写成usedn"t或usen"t。美式英语通常用A种形式，英式英语常用B种形式。例如：　　Youdidn"tusetodrink.你过去不喝酒。　　Theshopusedn"ttoopenonSundays.过去这家商店星期天不营业。　　(三)一般疑问句式：　　A)Did+主语+useto+动词原形……?　　B)Used+主语+to+动词原形……?　　美式英语通常用A种形式，英式英语用B种形式。例如：Didyouusetogoswimmingintheriverwhenyouwereyoung?你小时候经常在河里游泳吗?　　Usedhegotoschoolbybike?他过去骑车上学吗?　　(四)usedto用于省略句时，肯定式保留to，否定式不保留to。例如：　　——Usedyouplaybasketball?　　——你过去常打篮球吗?　　——Yes,Iusedto.(No,Iusedn"t.)　　——是的，经常打。(不，不常打。)　　Idon"twritetohimnow,butIusedto.我现在不给他写信了，但过去经常写。

二千年以前，赞比亚本地居民就已不断被外来居民吸收与融合。15世纪来，说班图语的居民开始进入赞比亚，且在17世纪至19世纪时达到高峰。19世纪中叶，欧洲殖民者及传教士开始进入当地。1888年，英国殖民者塞西尔·罗德斯从当地酋长手上取得了开矿权。同年，英国当局建立了南罗得西亚及北罗得西亚（分别为今津巴布韦与赞比亚）。1924年，北罗德西亚成为由英国殖民官员统治下的保护地。1953年，南北罗德西亚与尼亚萨兰（今马拉维）合并，组成罗德西亚与尼亚萨兰联邦（又称中非联邦）。1962年的联邦选举中，非洲人赢得了大多数立法委员会的席位。随后，立法委员会通过决议，呼吁北罗德西亚脱离联邦，并要求更广泛的自治民主权和公民权。1963年，中非联邦正式解散。1964年10月24日，北罗德西亚脱离英国独立，改称为赞比亚共和国。独立初期，赞比亚处境较为艰难。当时其中四个邻国——罗德西亚、南非管治下的西南非洲，以及葡萄牙殖民地葡属东非（今莫桑比克）与葡属西非（今安哥拉）都处于白人统治之下。由于赞比亚支持非洲南部各国的黑人政治团体，使得该国与罗德西亚间的关系紧张，最终两国边界更因而关闭。其后，由中华人民共和国援建的坦赞铁路由此带来的严重的债务问题。赞比亚债台高筑，2020 年 11 月成为第一个在疫情流行期间拖欠部分美元计价债券债息的非洲国家。此外，赞比西河上的卡日巴水电站也提供了足够的能源。
