曲线上每个点表示该情况下都是沉淀溶解达到平衡的状态,c错的是因为它没有把银离子浓度平方.至于b选项是对的,加入额外的重铬酸根离子,由于ksp不变,银离子一定会减少.因此还应该落到曲线上去

曲线是指在温度为T时不再溶解的Ag与CrO4的函数。
X点时离子积大于Ksp,有沉淀析出。
关于B选项,它说的不是平衡状态,是刚加完K2CrO4时的状态,当时有沉淀析出。

解题思路:重力势能的大小与物体的质量和下落高度有关,下落高度相同时,质量越大,重力势能越大;质量相同时,下落高度越大,重力势能越大;皮球下落过程中,具有的重力势能转化为动能,与地面碰撞接触时又转化为弹性势能,弹性势能的大小与物体的形变大小有关,形变越大,弹性势能越大.

从图中A、B的印迹看出,B球的形变大,说明它原有的重力势能大;在质量相同的情况下,高度越高,重力势能越大.
故答案为:B;高度.

点评:
本题考点: 探究影响物体势能大小的因素.

考点点评: 解答本题注意所用的研究方法:控制变量法,转换法;掌握重力势能与弹性势能的影响因素以及重力势能、动能、弹性势能的转化情况.

解题思路:

根据概率的求法,找准两点:①全部等可能情况的总数;②符合条件的情况数目;二者的比值就是其发生的概率。因此,

根据轴对称图形的概念,轴对称图形两部分沿对称轴折叠后可重合,白色的小正方形有12个,而能构成一个轴对称图形的有2个情况

使图中黑色部分的图形构成一个轴对称图形的概率是:

Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.
A. Talk slowly.
B. Concentrate on the topic.
C. Express your feelings.
D. Notice the details.
E. Use the best words.
F. Introduce something interesting.

小题1:
Generally, good talkers don’t rush into a conversation. They take their time when they think about something and when they say it out loud. They act as if they have all the time in the world. This makes them the center of attention. Try this way of talking and you will create the same effect.
小题2:
People with good conversation skills tend to notice the kind of things that the average person doesn’t notice, and to bring such details into the conversation. They may notice and point out an interesting ring on the other person’s hand, a certain foreign accent, or a certain voice tone they use when saying a name. Thus, such individuals impress people in a very elegant manner.
小题3:
It’s very rare to meet a person who is comfortably talking about their emotions and how certain things make them feel, especially with strangers. Yet this way of talking is a real virtue. Don’t just present the facts. Keep in mind that it is at the emotional level that people connect best.
小题4:
Anyone can talk about the news or express basic opinions. But good talkers can frequently tell you something you didn’t know and that you’ll find interesting and fascinating. This is why it’s good to have knowledge into fields such as psychology or sociology, and bring such knowledge out at the right moments in a conversation.
小题5:
The ability to talk smoothly has a lot to do with choosing the precise words to convey your feelings or thoughts. Constantly develop your vocabulary and practice communicating as accurately as possible. It will help you develop a way with words and allow you to express yourself more easily.

解题思路:根据题意,涂黑一个格共6种等可能情况,结合轴对称的意义,可得到轴对称图形的情况数目,结合概率的计算公式,计算可得答案.

根据题意,涂黑每一个格都会出现一种等可能情况,共出现6种等可能情况,
而当涂黑左上角和右下角的黑块时,不会是轴对称图形,其余的4种情况均可以,
故其概率为[4/6]=[2/3];
故选D.

本题考点: 轴对称图形;几何概率.

UNICEF reports that 40 million children below the age of 15 suffer from abuse(虐待) and neglect. The USA National Committee to Prevent Child Abuse finds 3 million new reports of child abuse or neglect every year.
According to such information on human rights abuses of children, the United Nations declared 2010 as the International Year of Youth. In answer to the common human rights abuses of young people, Dr. Mary Shuttleworth of Youth for Human Rights International(YHRI) recently completed her seventh annual World Tour to five continents in eighty days. The purpose of the tour is to promote the United Nations Universal Declaration of Human Rights to tens of thousands of children and officials.
According to UNICEF, 1.2 million children are illegally traded all over the world every year.
Sold as goods, these children are forced into inhuman labor, denied basic education and robbed of their childhoods. Youth who do not know their rights are easily cheated by ill-intentioned men. That is why YHRI thinks highly of education.
“When the United Nations declared 2010 as the International Year of Youth, I knew that their human rights had to be greater than ever,” Dr. Shuttleworth said. The tour reached Mexico, Guatemala, Panama, Ecuador, Brazil, South Africa, Swaziland, Portugal, Sardinia, Sicily, Italy, Greece, Taiwan, Japan, Hawaii and Los Angeles.
The YHRI World Tour 2010 has reached tens of thousands of students as well as officials, educators, and religious leaders and thus promotes human rights education to millions more.
小题1: 2010 was declared as the International Year of Youth because ______.
A.3 million children reported their information to the UN
B.many children are suffering from ill-treatment and neglect
C.children are illegally traded throughout the whole world
D.human rights abuses of young people have been avoided
小题2:According to para. 2, Dr. Shuttleworth first started her annual World Tour in _____.
A.2000 B.2004 C.2008 D.2010
小题3:Youth for Human Rights International is paying attention to education because _______.
A.education should serve most children
B.too many children are forced to leave school
C.children who know their rights will make more money
D.children who know little about their rights are easily cheated
小题4:According to the passage, the YHRI World Tour 2010 _______.
A.has almost stopped the child abuse B.has reached different areas and people

The disappointment stayed on the teacher’s face. Suddenly she that Laiq liked strawberries. She thought maybe he didn’t like apples and that was why he couldn’t answer the question. This time with an excitement in her she asked, “If I give you one strawberry and one strawberry and one strawberry, then how many will you have?”
Seeing the teacher , young Laiq calculated on his fingers again. There was no pressure on him, but a little on the teacher. She wanted her new to succeed. a hesitating smile young Laiq replied, “Three?”
The teacher now had a smile. Her approach had succeeded. She wanted to herself. But one last thing remained. she asked him, “Now if I give you one apple and one apple and one more apple , how many will you have ?”
Confidently Laiq answered, ‘Four!” The teacher was “How Laik , how?” She demanded in a little annoyed voice.
In a voice that was and hesitating young Laik replied, “Because I already have one in my bag.”
The story tells us: someone gives you an answer that is from what you expect, don’t think they are wrong. There shall be an angle(角度) that you may not have thought about yet.

请教一个水流导光的问题
有一个暗盒(内壁涂黑),在暗盒正对的两侧各开一个小孔,其中一个小孔用玻璃封住,让一激光束从装玻璃的小孔射入,并从另一个小孔直线射出.现在往暗盒中加水,当水从小孔流出时,我们用一块塑料板在暗盒下方接住水流.此时,我们发现水流通体明亮,并且在冲击塑料板的地方有一光斑.水流使光不再沿直线传播了.请问光为什么弯曲了呢?

这是全反射的作用,即光从水中射向空气,当入射角大于某一角度时,折射光线消失,全部光线都反射回水中.表面上看,光好像在水流中弯曲前进.实际上,在弯曲的水流里,光仍沿直线传播,只不过在内表面上发生了多次全反射,光线经过多次全反射向前传播.

A great many people are disappointed because of unrealistic expectations.
Walking up to a department store’s cloth counter, a(n) 26 young woman said,“I want to buy this material for a new dress. How much does it cost?”
“Only one 27 per yard,” replied the smirking (自鸣得意的) male clerk.
Not to be 28 back by the funny words, the woman said,” That’s fine! I’ll take ten yards.”
With 29 written all over his face, the clerk 30 measured out and wrapped the cloth, then held it out teasingly(戏弄地 ), 31 forward to receive his “ 32”.
The woman got the package quickly from the clerk and 33 to a little old man standing beside her. “Grandpa will pay the bill instead of me,” she 34 .
He was no 35 disappointed. But in the course of living, many people are 36 when others do not 37 their expectations. In order to be happy, some expectations must be 38 . These three particular 39 and unhealthy expectations are some of the main causes:
1.Expect too much 40 .When others say,“Thank you,” or in any way to show their gratitude, be 41 . It is a gift!
2.Expect others to make you happy. They simply cannot do that. Make yourself happy and 42 your joy with others.
3. Expect not to be 43 . At times, people will simply not come through for you in the way you need. 44 them and move on.
Get rid of these three unrealistic expectations and you can begin to expect more 45 right away!

请阅读下列科技新闻的信息:
A. One of the biggest science stories last year was the research on stem cells announced by South Korean scientist Hwang Woo-suk. But now it appears that the research was false. In June, Mr. Hwang reported that he and his team at Seoul National University had created eleven new stem cell lines.
B. Another major science story last year came from the United States. On December twentieth, a federal judge ruled that teaching “intelligent design” in public schools is a violation of the United States Constitution.
C. There was also news last year about the American space program. The American space shuttle(航天飞机) returned to the skies in July. Discovery and its seven-member crew made the first shuttle flight in two and one-half years. NASA had suspended shuttle flights following the deadly explosion of the shuttle Columbia in 2003.
D. Avian influenza(禽流感) was also a major science story last year. The H5N1 virus appeared in birds in Europe for the first time. Yet the only known human cases of the disease have been in East Asia. There have been about one hundred forty confirmed cases of bird flu since 2003. About half the people have died.
E. The World Health Organization advises patients to take a combination of four drugs to treat tuberculosis(肺结核). These four antibiotics must be taken for about six months to cure the disease. Some people, however, take the drugs only until they feel better. Discontinuing treatment is a mistake.
F. The researchers began the study in January, 2002. They called it SMART---Strategies for Management of Anti-retroviral Therapy. The scientists reached more than ninety percent of the target before they halted(停止) new enrollments last month. The researchers tested all the people for the level of CD-four cells in their blood. The researchers divided the patients into two groups.
阅读以下与科技有关的信息卡,然后匹配信息卡和与之相关的科技新闻:
小题1: Card 1 : One group stayed on continuous anti-retroviral therapy. They took their medicines every day. The other took them periodically. They took the drugs only when their CD-four count fell below two hundred fifty cells per cubic millimeter of blood.
小题2: Card 2 : Judge John Jones said that intelligent design is not science. He said it is a version of Christianity. So to teach it in public schools violates the law that requires the separation of church and state. Supporters of intelligent design criticize the science of evolution.
小题3: Card 3 : Stem cells have the ability to grow into other cells. Science magazine published the report. The new lines were made from the eggs of eighteen women and skin cells from eleven other people.
小题4: Card 4 : Many of the victims had touched or been around infected farm birds. But health experts around the world began warning that the bird flu virus could change into a form that is passed from person to person.
小题5: Card 5 : That explosion was the result of damage done to Columbia during its launch. A piece of lightweight protective material fell off the shuttle’s external fuel container. The object hit the shuttle at a high rate of speed and made a hole in one of the wings. This permitted extremely hot gases to enter the shuttle and destroy the spacecraft as it returned to the earth.

weiliny2k 共回答了14个问题 | 采纳率100%
解题思路:皮球从高空落下是重力势能转化为动能,落到地面时发生弹性形变,动能转化为弹性势能,形变越明显,说明皮球的弹性势能越大.

球从较高处落下,即球的重力势能较大,落地时转化成的弹性势能也越大,皮球发生的弹性形变就越明显,留下的圆斑也就越大,故应该是B圆斑.
故答案:B;质量相等,高度越高,重力势能越大,转化成的弹性势能越大,球的形变越大

点评:
本题考点: 势能的影响因素;动能和势能的转化与守恒.

考点点评: 本题综合考查了重力势能的影响因素、动能与势能的转化、弹性势能的影响因素的多个机械能的相关知识点,知识点本身难度较低,但多个知识点综合在一起,对学生的思维能力就有较高的要求.

解题思路:(1)甲图中,根据小磁针的N极指向,利用磁极间的作用规律可以确定通电螺线管的N、S极;
(2)乙图中,根据电流方向和线圈绕向,利用安培定则可以确定通电螺线管的N、S极.

(1)小磁针静止时N极指向左,由于异名磁极相互吸引、同名磁极相互排斥,可以确定螺线管的左端为N极、右端为S极;如图所示:
(2)结合图示的线圈绕向,电流从左端流入,利用安培定则可以确定通电螺线管的左端为S极、右端为N极;而异名磁极相互吸引,所以小磁针的右端为N极.如图所示:

点评:
本题考点: 通电螺线管的磁场;安培定则.

Animals perform many useful and amusing jobs. Dogs are particularly valuable in guiding the blind, 31 property(财产), finding 32 people, and hunting criminals(犯人). Horses are used in guarding herds(牧群),carrying men in lands where there are no roads, and helping farmers work their land. Pigeons(鸽子) 33 to carry messages. Wild animals from the jungles, forests and seas are very popular performers in 34 and motion pictures(电影). People realize that, 35 animals may not have the same intelligence(智慧) as 36 , they are clever enough to learn certain things.
The first thing a dog is taught is to 37 . It should not 38 too 1ong for him to learn commands. Simple orders, such as “sit, lie down,stay there, come here, ” can 39 be taught by a child.

This is 41 their masters welcome friends and invite them into their houses. However, some dogs will always 42 the postman who comes to 43 letters. One explanation for this behavior is that, although the postman comes to the house often, he never 44 the house. Therefore, the dog thinks the postman is someone 45 is not wanted, but keeps 46 back anyway.
Dogs are extremely useful as 47 for blind people. When a dog has been properly trained, he will lead his blind master in the right direction and keep him 48 danger. For example, seeing eye dogs 49a busy road when cars are coming, 50 their masters command(命令) them to do so.

The Internet has opened up a whole new online world for us to meet, chat and go where we’ve never been before.
But just as in face to face communication, there are some rules of behavior that should be followed when on line. 小题1: Imagine how you’d feel if you were in the other person’s shoes.
For anything you’re about to send: ask yourself, “Would I say this to the person’s face?” If the answer is no, rewrite and reread. 小题2:
If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so. 小题3: If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.
小题4: Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it’s a stupid question or an unnecessarily long answer, be kind about it. If it’s a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners doesn’t give you right to correct everyone else. 小题5: At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended.
It is not polite to ask others personal questions such as their age, sex and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don’t ask such questions.
A.It’s natural that there some people who speak rudely or make mistakes online.
B.Repeat the process till you feel sure that you’d feel comfortable saying the words to the person’s face.
C.Everyone was new to the network once.
D.The basic rule is simple: treat others in the same way you would want to be treated.
E. When you send short messages to a person online, you must say something beautiful to hear.
F. You should either ignore the person, or use your chat software to block their messages.
G. If you do decide to tell someone about a mistake, point it out politely.

解题思路:(1)已知了小磁针的磁极,根据磁极间的相互作用,可判断出通电螺线管的磁极,再由右手螺旋定则来得出电源的正负极.
(2)电磁继电器的实质是一个间接开关,它连接两个电路,是通过控制电路的通断来控制工作电路的通断的开关.此题中的控制电路的通断是由水位的变化来控制的.分析时要从控制电路入手.

(1)由图知:小磁针的磁极为:左N、右S,那么螺线管的磁极为:左S、右N;由右手螺旋定则可作图如下:

(2)当水位到达警戒水位时,控制电路接通,电路中有了电流,电磁铁具有磁性,吸引衔铁,衔铁下降,带动动触点下移,使工作电路中灯L2所在的支路接通,所以灯L2亮.

点评:
本题考点: 通电螺线管的极性和电流方向的判断;电磁继电器的组成、原理和特点.

考点点评: (1)主要考查了磁极间的相互作用、安培定则的运用,利用这两方面的知识将电源极性、电流方向、螺线管方向、小磁针方向联系在一起.
(2)电磁继电器在实际生活中经常用于自动控制如:水位报警器、温度报警器等.

However, 42 she was growing up, I found it increasingly hard to 43 with her.
Once her school required the parents to individually write an open and 44 letter to our children. I wrote a letter about a little golden-haired girl who had 45 me a bowl of soup when I needed 46 .
A week later, all the parents 47 together with our children. The students were allowed to make a few statements. I was 48 to hear what my daughter would say.
Finally my daughter 49 make her way up to the microphone. She said something like others and then 50 , “At this very moment, I just want to say …I love you, Father.”
Immediately people around me started 51 at me. For a teenage girl to say 52 in front of so many people, “I love you,” took a great deal of courage.
Since then I have 53 to understand I didn’t need to have any 54 about being a stepfather. I can still 55 honest love with the same little girl I met so many years before - carrying a bowl full of what turned out to be kindness. I can also be friends with the girl - my dear daughter.

解题思路:画出磁铁周围磁感线的分布情况,根据楞次定律判断感应电流的方向.

A、B,通过线圈的磁感线方向如图所示,
当右边磁铁S极断开时,穿过线圈的磁通量减小,根据楞次定律判断可知,电路中产生逆时针方向的感应电流,则有感应电流从a至b通过检流计.故A错误,B正确.
C、D通过线圈的磁感线方向如图所示,当右边磁铁S极断开时,穿过线圈的磁通量减小,根据楞次定律判断可知,电路中产生逆时针方向的感应电流,则有感应电流从a至b通过检流计.故C正确,D错误.
故选:BC.

点评:
本题考点: 楞次定律.

考点点评: 本题是楞次定律的简单应用,关键要把握两个条件:一是磁场的方向;二是磁通量的变化情况,再判断感应电流的方向.

探测红外线,为什么须将温度计的液泡涂黑

根据短文内容, 从下框A~F选项中选出能概括每段主题的最佳选项,并在答题卡上将该选项涂黑。选项中有一项为多余项。
A. Hard work
B. Principles for success
C. Active learners
D. A sense of humor
E. A successful sales team
F. A head start
小题1:___________
I was hired to do some training for a sales team from one of the largest companies in America. There were 16 people on this team. That year their sales (for the 16 of them) were close to 250 million — that’s right, a quarter of a billion dollars! Needless to say, it was an excellent and interesting time. I decided to learn a little bit myself, so I watched them closely to see what kind of people they were and to see what common characteristics they shared.
小题2:___________
They simply weren’t a terribly serious bunch of people. Instead, they saw that life was to be enjoyed and that means they were able to laugh a little bit. Sure, there were varying levels in this but they all had a sense of humor. They were able to laugh at circumstances, and they were able to laugh at themselves. It was quite refreshing and the most important key to their success, I’m sure.
小题3:___________
They didn’t come from families that gave them a free pass into the upper rank of the business world and they didn’t get a head start from upper outside universities. What got them to where they are now? Hard work! That’s right, another example that if you put your mind to it, work hard and get in the right situation, you can achieve great things! These folks work long hours and are disciplined in the work they do. And it is paying off.
小题4:___________
They were always occupied in the learning process. During my sessions they were attentive and listening. You could see their minds processing the information. They were asking questions and applying the material to their work and their lives. They wanted to improve in any way that they could. It was also interesting to watch them in their team meetings led by their sales manager. They were very interactive and were learning from one another. None of them was above learning from a colleague.
小题5:___________
What did I see in these successful people? The same things that can make you a success as you apply the principles to your own life: a sense of humor, hard work, and a desire to learn at every turn.

解题思路:分析题图:图示所示为人类“治疗性克隆”的大概过程,图中①为卵(母)细胞;②为核移植所得的重组细胞;③为滋养层细胞;④为内细胞团,其中的细胞属于胚胎干细胞;A表示核移植过程;B表示早期胚胎发育过程;C表示细胞分化过程.

(r)o中e表示细胞核移植;①为卵(母)细胞.
(2)经过程B得到的结构为囊胚,其中④为内细胞团,内细胞团细胞是未分化的细胞,被认为是胚胎干细胞;胚胎干细胞在体外培养条件下能保持只增殖不分化的状态.
(3)“治疗性克隆”的结果说明高度分化的体细胞的核仍然具有全能性.相同的胚胎干细胞,经过C过程可形成多种细胞,如有的是神经细胞,有的是血细胞,有的是肌肉细胞,究其本质原因是基因的选择性表达的结果.
(4)有一男子患有白血病,后经医生利用其出生时保留的脐带血进行治疗后康复,这种做法符合伦理道德,因为脐带血不是来自于胚胎,其中的造血干细胞属于成体干细胞.(或脐带血是身外之物,属于废物利用,符合伦理道德).
故答案为:
(r)细胞核移植(次级)卵(母)
(2)④未分化
(3)全能性基因的选择性表达
(4)符合,因为脐带血不是来自于胚胎,其中的造血干细胞属于成体干细胞

点评:
本题考点: 动物细胞核移植技术;基因工程的原理及技术;单克隆抗体的制备过程.

考点点评: 本题结合人类“治疗性克隆”的大概过程图解,考查动物体细胞核移植技术、胚胎干细胞、治疗性克隆等知识,要求考生识记动物体细胞核移植技术的概念、过程及应用,能准确判断图中各过程及各结构的名称;识记胚胎干细胞的概念及特点.
