sense(feeling) of urgency(tightness)

第一、文化的复杂性（culturecomplexity），从文化内部复杂程度对文化进行比较。一个文化内部内群体的数量与功能也是文化复杂性的一个重要标志（数量增加，对个体约束力降低，个体对群体忠诚度降低，流动性大，个体选择群体归宿增多；数量少，个体依赖群体，强调内部和谐和合作，与外群体竞争对抗，严格约束力，严厉的惩罚）。所以文化的复杂性可以到处文化的宽松与严厉这一维度。第二、文化的严厉与宽松（tightnessand looseness），即在同质性高的文化中，群体要求个体遵守群团体的规范，对于偏离群体规范的行为给予极大的惩罚和心理压力；在异质性高的文化中，群体的规范没有那么清除和严厉，可以容忍个体有一定程度的偏离。由此，全体文化表现进入个体主义和集体主义维度。第三、个体主义与集体主义，指个体如何处理个人行为目标和集体行为目标的关系。个体主义——个人目标助于群体目标之上，态度是比规范更具威力的社会行为指标；集体主义——自我与群体相互依赖，规范是比态度更具威力的社会行为指标。（有很多局限）他认为这三个维度直接影响着个体对自我、群我、角色与责任、共同合作、目标认同等心理边界的确定。

先把译文给出来：由于莱斯利的内心深处一直存在着那个疯狂（或狂热的，古怪的，变态的等等，要看上下文的语境来具体翻译）的想法，她感到一阵恐惧向她袭来。首先说一下，knot 的意思是：A feeling of tightness紧张感，比如：a knot of fear in my stomach在这里并不是“打结”的意思。还要注意几个地方，由于这属于文学上的语言，所以最好能用意译，不要拘泥于字面上的意思，这样才能翻译得更生动。as 在这里的意思是“因为，由于”，是表示原因的。at the back of her mind 可翻译为“内心深处”in her stomach 可以不翻译出来，因为汉语没有对应的“从胃里恐惧”这样的表达习惯，所以这里要按汉语的习惯来组织语言。至于要更准确，需要您给出上下文来具体判断。本人翻译仅供参考。

Losing hearing.失去听觉We have five senses, and one of the senses is hearing. For normal people, they can"t feel the importance of the senses. If we lose hearing one day, what should we do?我们有五个感官，其中之一就是听觉。对于正常人来说，他们不能感觉到感官的重要性。如果有一天我们失去了听觉，我们该怎么办？ It isn"t imaginable for us to lose hearing.First of all, there is no doubt that we can"t hear the surrounding voices. So there must be a difficulty to communicate with each other. Secondly, losing hearing means we are no more a healthy and normal people, we are diabled. What"s more, most people will look down us once we lose hearing. But on the other hand, quite a few famous people also loae hearing or some more, but they got a lot of achievements.对于我们来说失去听觉是不可以想象的。首先，无疑地我们不能听到了周围的声音，因此我们之间的相互交流肯定会有困难。其次，失去听觉意味着我们不再是一个正常健康的人，我们是残疾人。还有，一旦我们失去听觉，大多数人将会看不起我们。但是另一方面，许多著名的人也失去了听力或是更多，但是他们取得了巨大的成就。 In a word, we must be perish our health. Even if we lose one of the five senses, we can"t lose confidence.总之，我们一定要珍惜我们的健康。即使我们失去了一个感官，我们也不能失去信心。

　　分享一些中长篇的英文励志诗歌，一起来看看吧。下面是我给大家整理的中长篇励志英文诗歌，供大家参阅! 　　中长篇励志英文诗歌：Morning Song 　　Sylvia Plath 　　Love set you going like a fat gold watch. 　　The midwife slapped your footsoles, and your bald cry 　　Took its place among the elements. 　　Our voices echo, magnifying your arrival. New statue. 　　In a drafty museum, your nakedness 　　Shadows our safety. We stand round blankly as walls. 　　I"m no more your mother 　　Than the cloud that distills a mirror to reflect its own slow 　　Effacement at the wind"s hand. 　　All night your moth-breath 　　Flickers among the flat pink roses. I wake to listen: 　　A far sea moves in my ear. 　　One cry, and I stumble from bed, cow-heavy and floral 　　In my Victorian nightgown. 　　Your mouth opens clean as a cat"s. The window square 　　Whitens and swallows its dull stars. And now you try 　　Your handful of notes; 　　The clear vowels rise like balloons. 　　中长篇励志英文诗歌：From The Frontier Of Writing 　　The tightness and the nilness round that space 　　when the car stops in the road, the troops inspect 　　its make and number and, as one bends his face 　　towards your window, you catch sight of more 　　on a hill beyond, eyeing with intent 　　down cradled guns that hold you under cover 　　and everything is pure interrogation 　　until a rifle motions and you move 　　with guarded unconcerned acceleration-- 　　a little emptier, a little spent 　　as always by that quiver in the self, 　　subjugated, yes, and obedient. 　　So you drive on to the frontier of writing 　　where it happens again. The guns on tripods; 　　the sergeant with his on-off mike repeating 　　data about you, waiting for the squawk 　　of clearance; the marksman training down 　　out of the sun upon you like a hawk. 　　And suddenly you"re through, arraigned yet freed, 　　as if you"d passed from behind a waterfall 　　on the black current of a tarmac road 　　past armor-plated vehicles, out between 　　the posted soldiers flowing and receding 　　like tree shadows into the polished windscreen. 　　中长篇励志英文诗歌：Digging 　　Between my finger and my thumb 　　The squat pen rests; as snug as a gun. 　　Under my window a clean rasping sound 　　When the spade sinks into gravelly ground: 　　My father, digging. I look down 　　Till his straining rump among the flowerbeds 　　Bends low, comes up twenty years away 　　Stooping in rhythm through potato drills 　　Where he was digging. 　　The coarse boot nestled on the lug, the shaft 　　Against the inside knee was levered firmly. 　　He rooted out tall tops, buried the bright edge deep 　　To scatter new potatoes that we picked 　　Loving their cool hardness in our hands. 　　By God, the old man could handle a spade, 　　Just like his old man. 　　My grandfather could cut more turf in a day 　　Than any other man on Toner"s bog. 　　Once I carried him milk in a bottle 　　Corked sloppily with paper. He straightened up 　　To drink it, then fell to right away 　　Nicking and slicing neatly, heaving sods 　　Over his shoulder, digging down and down 　　For the good turf. Digging. 　　The cold smell of potato mold, the squelch and slap 　　Of soggy peat, the curt cuts of an edge 　　Through living roots awaken in my head. 　　But I"ve no spade to follow men like them. 　　Between my finger and my thumb 　　The squat pen rests. 　　I"ll dig with it.

我有你说的这种烟，需要加，嗯嗯薇灬信:zirou0819......The lowest level, your situation is only 9 class disable, highest no dysfunction in general tenth level. Disables need to professional grade我们可以观测到的宇宙始于大爆炸，这句话已经是描述宇宙最基本的设定了！而宇宙在过去就表现的更热、更密集、更紧凑、膨胀得更快。然而今天的宇宙仍然在膨胀，没有引力束缚的一切在未来都将无限的膨胀下去。我们可以简单的想象一下：今天的宇宙可以当作一个有限体积的球体，所有的物质和能量都包裹在里面。如果我们回溯到过去，同样数量的粒子会被封闭在一个更小的球体中。现在你应该知道，我们处在一个由广义相对论控制的宇宙，在这个宇宙中，空间和时间是相对于任何观察者的能量、动量和位置而言的。假设你的寿命很长啊，无限长，你从现在开始观察一个本星系群外的一个星系，这一看就是数十亿年，你从来没有间断过，你会发现什么？你会看到这个星系的位置发生了很大的变化！就像上图中葡萄干在发酵的面包中一样改变了位置。但是请注意，葡糖干它自己并不会膨胀，膨胀的是周围的空间，所以它们之间的距离增加了。类似的像行星，恒星，星系，甚至星系群和星系团这样的结构本身也不会随着宇宙膨胀，因为它们已经被引力束缚住了！膨胀的只是那些没有被各种力束缚住的物体！换句话说，你的腰围可能在扩大，但你不能把这归咎于宇宙膨胀！因为你已经被电磁力束缚住了，宇宙膨胀是左右不了你的！

这句话的意思是：什么是典型的公差(出版规格闷)和你的工作吗?

Para 1 These days, it seems that almost all of us are too serious. My older daughter often says to me, “Daddy, you"ve got that serious look again.” Even those of us who are committed to non-seriousness are probably too serious. People are frustrated and uptight about virtually everything -- being five minutes late, having someone else show up five minutes late, being stuck in traffic, witnessing someone look at us wrong or say the wrong thing, paying bills, waiting in line, overcooking a meal, making an honest mistake -- you name it, we all lose perspective over it.近来,好像几乎所有的人都太严肃了。我的大女儿经常对我说:“爸爸,你又是那副严肃的表情了”。即使我们中那些致力于不严肃的人也可能很严肃。人们会对几乎一切感到挫败和焦虑---迟到五分钟,别人迟到五分钟出现,被困在路上,发现有人正看着我们的错误或说错的话,支付帐单,排队等候,煮坏了一餐饭,犯了个诚实的错误——你能列举出来的，我们几乎已经意识不到了。Para 2 The root being uptight is our unwillingness to accept life as being different, in any way, from our expectations. Very simply, we want things to be a certain way but they"re not a certain way. Life is simply as it is. Perhaps Benjamin Franklin said it best: “Our limited perspective, our hopes and fears become our measure of life, and when circumstances don"t fit our ideas, they become our difficulties.” We spend our lives wanting things, people, and events to be just as we want them to be -- and when they"re not, we fight and we suffer.焦虑的根源是无论如何，从我们的期待来看，我们不愿意接受生活的不同。很简单,我们想希望生活有特定的方式,但是却没有。生活就像它原有简单的样子。也许本杰明•富兰克林说的最合适:“我们有限的视角,以及我们的希望和恐惧成为衡量生活的尺码,而一旦情况不适合我们的想法,这些就成为我们的困难“。我们穷其一生,想要的东西,就是希望人和事向我们期待的一样---当情况并不如此时，我们会在挣扎和痛苦。Para 3 The first step in recovering from overseriousness is to admit that you have a problem. You have to want to change, to become more easygoing. You have to see that your own uptightness is largely of your own creation -- it"s composed of the way you have set up your life and the way you react to it.从过度严肃中恢复的第一步是承认你有问题。你必须要改变,变得更放松。你必须看到你自己说的焦虑在很大程度上是你自己的造物——它是由你创造的生活方式以及你的应对构成的。Para 4 The next step is to understand the link between your expectations and your frustration level. Whenever you expect something to be a certain way and it isn"t, you"re upset and you suffer. On the other hand, when you let go of your expectations, when you accept life as it is, you"re free. To hold on is to be serious and uptight. To let go is to lighten up.下一步就是要了解你的期望和挫折感水平之间的联系。当你期待某件事以特定方式而事实并非如此,你会不安和痛苦。另一方面,当你放开你的期望,当你接受生活本来的样子,你就会感到自由。紧紧抓住会严肃和焦虑，而放手就心情轻松愉快。Para 5 A good exercise is to try to approach a single day without expectations. Don"t expect people to be friendly. When they"re not, you won"t be surprised or bothered. If they are, you"ll be delighted. Don"t expect your day to be problem free. Instead, as problems come up, say to yourself, “Ah, another hurdle to overcome.” As you approach your day in this manner you"ll notice how graceful life can be. Rather than fighting against life, you"ll be dancing with it. Pretty soon, with practice, you"ll lighten up your entire life. And when you lighten up, life is a lot more fun.下一步就是要了解你的期望和挫折感水平之间的联系。当你期待某件事以特定方式而事实并非如此,你会不安和痛苦。另一方面,当你放开你的期望,当你接受生活本来的样子,你就会感到自由。紧紧抓住会严肃和焦虑，而放手就心情轻松愉快。

There are a number of types of pneumoconiosis, but the mainfocus is upon (about) miners pneumoconiosis. This is caused by the inhalation ofaerosols such as nitrogen oxides, sulphur oxides and carbon monoxide. The dustin the mines are ( is ) airborne, often not as (so) dangerous if inhaled infrequently (frequently),however miners inhale the aerosols every day for several years which can causedisease (West, 2007). Aerosols inhaled into the lungs effect (affect) the cilia, andcause them to be paralyzed making it difficult for the mucociliary system towork efficiently. It also affects alveolar macrophages which usually engulfs（engulf）materials such as silica. To be honest this could affect a person"s breathing,causing a persistent cough and a tightness of chest (Pnuemoconiosis,2011).Unfortunately there are （is ）no treatment for the disease itself, however treatmentcan be provided to ease the pain of the symptoms (Dhingra,2010). To determinewhat （which）treatment is needed for pneumoconiosis a scan needs to be taken toevaluate the extent of the disease. The disease is often monitored over aperiod of time and a change of lifestyle could be recommended. The patient willoften gets immunised against diseases such as influenza. Normally antibioticsand physical therapy are used to help the movement of mucus in the persons（person"s）system, as well as medication that can be inhaled to help with( 去掉 ) their breathing.The majority of people suffering from pneumoconiosis are over the age of 50,approximately 6 out of one hundred thousand people suffer from the disease andthe mortality rates (rate)are 800 deaths per year in the United Kingdom(Pneumoconiosis, 2011).Asbestosis is also a lung disease caused from the inhalation of industrial materials,however it is classified differently to (as)pneumoconiosis. Asbestolosis is due tothe inhalation of asbestos a fibrous material found in certain buildings, alsofrom mining. Asbestos resists dilution so _it__ can remain for a long period of timein a person"s system, so when settled in the lungs they_ _have long term effects(Selikoff, 1978).问题补充：(接上)Asbestosis is a serious disease which is alsoincurable and can often result in an early death. There are two types ofasbestosis; mesotheliomia and fibrous thickening. The disease causes thescarring of the lung tissue, and affects how the lungs work. The scaring of thelungs can cause respiratory problems, shortness of breath and chronic coughing.There is a found to be a correlation between asbestosis and primary lung cancer(House of commons, 1999). Like pneumoconiosis there is no treatment for the disease, but symptoms are monitored and managed over time. To help with the increase in the mucus in the lungs, physical therapy may be used to help remove a large amount of mucus (Selikoff, 1989). With respiratory problems oral medication that can be inhaledmay help improve their breathing, as well as over ( 去掉) the counter drugs such asparacetamol and ibuprofen. Asbestosis太长，费眼。欢迎追问！

　　在学习、工作乃至生活中，大家对作文都再熟悉不过了吧，作文是人们把记忆中所存储的有关知识、经验和思想用书面形式表达出来的记叙方式。那么问题来了，到底应如何写一篇优秀的作文呢？下面是我帮大家整理的英语话题作文6篇，希望对大家有所帮助。 英语话题作文 篇1 　　Ambition is the decision one makes and the resolution with which he carries out that decision. It provides us with the required driving force to accomplish any undertakings in our life. Just as Joseph Epstein, a famous American writer put it, “And as we decide and choose, so are our lives formed.” Indeed, once we make up our minds to choose to do something, then our life becomes meaningful and specifically orientated. This notion of life, as far as I observe, is closest to truth and does apply to almost all aspects of life. 　　First things first, ambition renders us a sense of mission. No matter what decision you make you have to be responsible for your choice. Your choice procures you a sense of orientation, or more specially a sense of mission. And only a strong mission may enable one to accomplish greatness. Caesar of the ancient Roman Empire was urged by his ambition “I came, I saw, I conquered.” And became an unrivaled empire builder in the history of Rome. John Milton, stimulated always by his ambition that aimed at writing some “mighty lines” which England would unwillingly forget, had in due time secured his position as the second Shakespeare in the history of English literature. 　　In the second place, ambition can bring one"s potentials to the full. Ambition may well serve as a catalyst activating one"s dormant potentials. Without ambition one"s potentials will remain slumbering like a dormant volcano. A case in point is Ms Zhang Haidi, a Chinese Helen Keller. It was her ambition to be a useful person has turned the almost paralyzed Zhang Haidi into a well-accomplished figure whose achievements would dwarf those of some normal people aim at the sun, though, at worst, they may probably land on the moon. 　　Influential as it is upon us, however, ambition must be channeled in the right direction. If wrongly directed, one"s ambition may bring havoc on him and others. Hitler, whose ambition was to conquer Europe by whattever evil means, finally turned him into a demon. It was this demon that almost cast Europe into an unfathomable abyss of anguish and suffering. Another case is Macbeth whose ambition was to become the king of Scotland. However, his ambition was materialized by the murder of King Duncan. Consequently, unbearable guilt and psychological agony drove him to his tragic doom. 　　To sum up, ambition can benefit us tremendously if wisely and correctly channeled, otherwise it may ruin others and ourselves. A poet says: life can be bad; life can be good; life can be dirty; life can be sad,; life can even be painful. In my mind"s eye, a person can make his life beautiful, meaningful and rewarding and stand out as a respectable personage if he is motivated by a well-orientated ambition. 英语话题作文 篇2 　　Ways to Improve china"s tourism 　　Tourism is now becoming a major industry throughout the world. However，tourism in China is not as developed as it should be. If the following is done，China"s tourism will definitely be improved. 　　First，our places of interest should be better advertised throughout the world to attract more tourists. Second，facilities should be provided to ensure that tourists enjoy their trip. Finally，the quality of service should be improved. 　　Don"t tell people their ideas are bad unless you"ve got a good one. 　　Use of Free Time 　　Some people may be so busy that they never have a spare moment，but it would be hard to find such people in contemporary times. Working hours are shorter and vacations longer，and there are more and more ways to spend the weekends. Aside from eating and sleeping，what do people do during the many hours when they are not at work or at school？ 　　Use of free time often discloses much about one"s tastes，values，interests and personality. What may be one man"s leisure，however，might be another man"s work. In leisure hours，some may turn to the humanities：literature，magic，art and here we might also mention movies and television. Others participate in sports，politics，voluntary work or hobbies at home. Still others like parties，travelling，or just loafing. 　　Obviously，the use of free time is a good means of relaxation，but its benefits go beyond this. All things people do in leisure hours enable them to gratify their wishes. This can contribute to intellectual growth and promote social activities as well. 　　So the good use of free time will make life rich，colorful and rewarding. 英语话题作文 篇3 　　This picture is simple but significant. As is vividly shown in the picture, wearing traditional Chinese costume, a foreigner is saying “Happy New Year” to a Chinese girl in Chinese, even though his pronunciation is not accurate enough. There is no doubt that the picture implies that a growing number of foreigners are starting to be interested in Chinese culture in this day and age. 　　Why should this phenomenon take placeThere are generally three factors accounting for it. First of all, due to the fast economic and social development, the world is becoming smaller and smaller. Accordingly, international cultural exchange is becoming increasingly frequent. Besides, learning traditional Chinese culture, which is priceless spiritual treasure, can give those foreign friends a new perspective of the outside world. Last but not least, this kind of cultural exchange is beneficial for both our Chinese and foreign friends to broaden our horizons, widen our knowledge, and eich our experience. 　　From what has been discussed above, we may come to a conclusion that our traditional culture is popular among the whole world and should be preserved and cherished. Therefore, the mass media, such as television, radio and Internet should try best to propaganda and advocate it. As for ourselves, we should cultivate the awareness of learning national culture. Only in this way can we have opportunities to expect a more vigorous and prosperous world to come. 英语话题作文 篇4 　　 1.高中英语作文：英语的重要性 　　1.

Last months several places in Beijing were blanketed with thick yellow fog. Everything around disappeared from oursight. Some highways were closed. Traffic jams were commonly seen in the streets. Many people, especially children and seniors, even found it difficult to breathe. As a result, local hospitals were crowded with people who had problems with their noses and lungs. Part of the cause was the dry weather, but the severely damaged environment contributed a lot to this nightmare. Personally I didn"t get any health problems in the haze because I stayed mostly indoors.But to make a significant change we really have to do more to protect our environment. To live a better life we have to push on with the economy, but it wound be meaningless if we have to achieve it at the cost of our breathing air. 　　Regards! 　　Yours，Li Hua

是老挝的缩写。

food safety与food security区别：food safety指的是食品的卫生安全（微生物时间，重金属事件）等等。food security 指的是粮食的供应是否安全无虞。

注意啊，这个“佬”字是我自己杜撰选的字，是根据村里人的土话方言发音猜的。 它发轻声韵“lao1”，因为要与後面我妈家的“姥”发三声上声韵“lao3”相区别。 这个很重要，否则会叫乱套的，“佬lao1”和“姥lao3”是差了一辈的。 再往上一辈的称呼是“老佬爷”、“老佬嫲”，这个“老”也是我杜撰选的，根据土话叫法的口音猜的。 按理说，再上一辈的话，就继续在前面加个“老”字就可以了，比如“老老佬爷”、“老老老佬爷”。 不过，一个是没有活那麼久的差辈的长辈，再一个是讲究“五服”之内为亲的一家人，我、我亲爸、我亲爷爷、我亲佬爷、我亲老佬爷，五代，够了，所以不管是不是还有更高的辈分，叫到“老佬爷”就不再继续加“老”字了。 就是说到“老佬爷”就最高了，再高也是这麼叫了，统一了。 我印象里应该是这么叫的，因为村西头有个比我爸还年轻的“佬爷”，他妹妹是我的初中数学老师，我在学校里叫她老师，出了校门我叫她“老佬姑”。

But do you know how to protect your eyesight? First, don"t keep your eyes working for a long time. You"d better have a rest by looking in the long distance after you have studied an hour or so.

中文的意思就是定义变量。Dim就是定义变量。在Basic语言中，通过定义数组的大小，用DIM，英文全称Dimension，中文意思是尺寸的意思。在VB中则延伸DIM用来定义变量。显式定义：Dim 变量名 As 类型。隐式定义：使用类型说明符。经过dim定义后的代码更加稳定，IIS解读时不易出现服务器问题。　出现“处理url时服务器出错”问题时，可以给变量添加dim予以避免。

　　在我们平凡的日常里，大家都有写作文的经历，对作文很是熟悉吧，作文要求篇章结构完整，一定要避免无结尾作文的出现。那要怎么写好作文呢？下面是我精心整理的话题英语作文9篇，仅供参考，欢迎大家阅读。 话题英语作文 篇1 　　The desire for good health is universal. If a person feels ill all the time, he will in most cases old a pessimistic view toward things and lead a sad life. What"s more, no matter how ambitious he could be, he might just be too weak to carry out any of his grand plans. Hence, though many people are seeking after wealth or power, they always attach the greatest importance to health. 　　Since a sick person tends to be unhappy, people worldwide have spared no efforts to slay healthy. They pay special attention to what they eat so that they get neither malnourished nor overweighed. Besides, people, especially, those engaged in mental jobs, create numerous indoor or outdoor exercises to keep energetic, eg. working in the field as gardeners and farmers, going to work on foot, cycling to work, having a walk after supper, climbing mountains, traveling, attending all kinds exercises in health clubs, etc. 　　To be healthy also includes being mentally healthy. It is another important guaranty for people to live or work well. So, experts suggest that we keep a calm, peaceful and open mind and try to avoid extreme emotions like fierce anger, extreme sadness and excitement. Therefore, exercises like Taiji Exercise, traveling, etc. which can benefit people both physically and mentally are popular not only in China but also in other countries. 　　As far as I am concerned, in addition to a balanced diet and a peaceful mind, I lack pleasure the performing various types of exercises. And playthg basketball and badminton are my favourite games. 话题英语作文 篇2 　　I went hiking to a mountain with my friends last summer。 　　It was a good trip at the beginning but something unexpected happened on the half way。 One of my friends suddenly felt a terrible pain in his stomach and he couldn‘t move any further。 Nobody knew what to do。 　　One girl tried to call her mum with her mobile phone but there was no signal in the mountain area。 Luckily we brought a tent with us。 We put it up and let him rest in it。 He took some medicine。 Then he drank some water， and ate some food。 After a while， he felt much better and we walked on。 We all enjoyed ourselves on the top of the mountain。 话题英语作文 篇3 　　Is it Good for College Students to fall in love in School? 　　College students have more freedom than before and they also grow more and more mature in physical and mental. So it is natural that they would like to fall in love with someone. As a result, campus love becomes popular in university. For this phenomenon, people opinions vary. In my opinion, I dont agree with that phenomenon. 　　跟以前相比，大学生拥有更多的自由，而且在身心上他们也在慢慢地变得越来越成熟。所以他们想谈恋爱是很自然的。结果校园恋爱在大学中就变得很普遍。对于这一现象，人们众说纷纭。在我看来，我是持反对意见的。 　　First of all, falling in love with others cost a lot of money. When two people have that kind of relationship, they will go out with each other often. When they are going out, they have to spend more money. During the dating, the boy may try his best to buy things to make the girl happy. While the girl may start to make up or buy more beautiful clothes to make herself look better. All these need money. However, university students are still students. They have no income. Their money is from their parents. Falling in love with someone will increase the burden of their family and themselves. 　　首先，恋爱需要花费很多钱。当两个人是那种关系的时候，他们就会经常一起出去。出去的时候就要花比较多的钱。约会中，男孩子会尽自己最大的努力去买东西给女孩让她开心。而女孩也会开始化妆或者买一些漂亮的衣服来让自己看起来更美丽。这些行为都是需要钱的。然而，大学生仍然还是学生。他们没有收入。他们的钱是父母给的。恋爱会增加家庭和自己的负担。 话题英语作文 篇4 　　The Prevalence of Western Holidays-it is noticeable that western holidays are becoming increasingly popular day by day, while Chinese traditional holidays are being somewhat neglected. Young people in China who are ignorant about Chinese traditional holidays are crazy about Christmas or Valentine"s Day. 　　There are several possible reasons for this phenomenon. First, western nations, such as the United States and Britain, are powerful and dominant in every aspect. 　　Everything in these countries is assumed to be superior and adored by some modern young people. Second, the prevalence of English as a world language and the development of globalization enable western cultu 　　re to prevail in China. Last but not least, some Chinese people have blind faith in foreign things while treating our own possessions with contempt. 　　I am critical of this trend. China boasts a brilliant history and splendid traditions. Chinese tradition should be preserved and promoted. If this trend is allowed to continue, the priceless heritage of our ancestors will be replaced by western traditions. Nobody expects such a consequence. So let us join hand in hand to protect Chinese tradition, especially traditional holidays.

As we have learned English for a very long time, we will complain about it, we always make the joke that the foreigners should learn Chinese. Now, it is not the joke anymore, the world"s watching China, more and more foreign people are interested in Chinese, they have learned Chinese. When we open the TV, we can find that a hot show called Chinese Bridge, it is a competition for the foreign students to show their Chinese. I have seen the show, I was very impressed, the foreign students spoke Chinese so well, they knew our culture, they had enthusiasm, which made them enjoy learning Chinese. We should learn from the foreign students, they show us the way to learn a language well. 　　从我们上学起，就要学习英语，英语已经成为了主要的科目之一。由于我们要学习英语 　　很长一段时间，总会抱怨，我们会开玩笑说老外应该学习中文。如今，这不再是个玩笑了，全世界都在关注中国，越来越多的外国人对中文感兴趣，他们已经开始学习中文。当我们打开电视，可以发现一档热门的节目叫“汉语桥”，这是给外国学生展示汉语的竞赛节目。我看过节目，印象深刻，外国学生能把汉语讲得很好，我们了解我们的文化，有热情，这使得他们乐于学习汉语。我们应该向外国学生学习，他们给我们展示了学好一门语言的方法。 话题英语作文 篇6 　　smiling 　　i think smiling is as important as sunshine. smiling is like sunshine because it can make people happy and have a good day. if you aren?t happy, you can smile, and then you will feel happy. someone may say, “but i don?t feel happy.” then i would say, “please smile as you do when you are happy or play with your friends happily. you will really be happy again.” 　　smiling can let you have more friends.so i say, smiling is like a flower. it will give you happiness. 　　微笑 　　我认为微笑是一样重要的象阳光。 微笑是象阳光，因为它可能使人愉快和有一个早晨好。 如果您不是愉快的，您能微笑，您然后将感觉愉快。 某人也许说， “但是我不感到愉快”。 然后我会说， “请微笑，您，当您愉快地是愉快或戏剧与您的朋友。 您真正地再将是愉快的”。 　　微笑可能让您有更多朋友。如此我说，微笑是象花。 它将给您幸福。 话题英语作文 篇7 　　 1.高中英语作文：英语的.重要性 　　1.

But what kind of person can be accepted as friend? Lots of people are classmates and aren"t friends. Lots of people are lovers but aren"t friends. You can appreciate or admire someone, but that doesn"t make them a friend. If their attitude is "for better or worse," if they stick with you through thick and thin, that"s when you can tell it"s friendship. 　　The term, friend, covers a wide range of meanings. It can be a nodding acquaintance, a comrade, a partner, a playmate, a brother, etc. As life is full of obstacles and conflicts, we need friends to give us supports to get through tough times, we also need friends to give us warnings to go against danger. True friends share not only joy but, more often than not, they share sorrow and difficulties. 　　With friendship, life is happy and harmonious. Without friendship, life is hostile and unfortunate. I have friends in the rank and file. Some are rich and in power. Some are low and common. Some are like myself, working as an ordinary teacher, reading and writing and content with the simple life. To many of my friends, I know what to treasure, what to tolerate and what to share, I will never forget my old friends and keep making new friends. I will not be cold and indifferent to the poor friends and will show concern for them, even if it is only a comforting word. 话题英语作文 篇9 　　6月5日（ June 5）是世界环境保护日， 我们周围的环境变得越来越糟糕，污染越来越严重。环境问题影响着人们的工作，学习，生活等，而我们的工作，生活，生产等又使环境污染越来越严重。。。。。。如何保护我们的环境？ 请以“ How to protect/save our environment/world？ ”为题写一篇短文。 　　提示：存在问题：1。水污染越来越严重;2。砍伐森林严重;3。 大气污染严重;4。 白色垃圾等。 　　要求：如何改善/保护环境？至少：3———4个方面， 80字左右的。 　　 ★ 范文 　　How to protect/save our environment/world？ 　　The environmental pollution is worse and worse /more and more seriously today。 Water is polluted; we have no clean water to drink。 Many trees are cutting down， some animals is getting less and less。 Some factories are pouring dirty air in the sky， the population is increasing faster and faster， resources are getting less and less…etc。 Not only does it affect our lives and health， it but also has a great affection in the future。 People"s health has been greatly affected by air， noise and water pollution。 Many people died of diseases。 In order to live a better life， we need protect our world。 　　We shouldn"t throw away rubbish everywhere。 We want to recycle， reduce， reuse things 。Don"t waste things。 This saves money and reduces pollution。 Use things for as long as possible。 We don"t use plastic bags。 We must plant more trees and stop the people cutting them 。We hope our world becomes more and more beautiful。

这个问题提的好！food safety：通常是指食品质的安全，也就是现在“食品安全”的概念，但更强调的是针对一些偶然的、食品意外污染的危害。food security：通常是指食品量的安全，即是否有能力得到或者提供足够的食物或者食品。security在餐馆业是指保护消费者和雇员不受暴虐和犯罪危害。FAO对food security的定义：指所有人在任何时候都能在物质上和经济上获得足够、安全和富有营养的食物以满足其健康而积极生活的膳食需要（世界食品首脑会议行动计划第一段）。这涉及四个条件：（1）充足的粮食供应或可获得量；（2）不因季节或年份而产生波动或不足的稳定供应；（3）具有可获得的并负担得起的粮食；（4）优质安全的食物。Food Safety”与“Food Security”所针对食品的安全性是密切相关的，但所针对的引起食品安全问题的原因是各有侧重的。Food security refers to the availability of food and one"s access to it. A household is considered food secure when its occupants do not live in hunger or fear of starvation.参考资料：Food security exists when all people, at all times, have access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. (FAO)Food security for a household means access by all members at all times to enough food for an active, healthy life. Food security includes at a minimum (1) the ready availability of nutritionally adequate and safe foods, and (2) an assured ability to acquire acceptable foods in socially acceptable ways (that is, without resorting to emergency food supplies, scavenging, stealing, or other coping strategies).
