全新版大学英语综合教程2课文原文及翻译
全新版大学英语综合教程2课文原文及翻译(总6页)--本页仅作为文档封面，使用时请直接删除即可----内页可以根据需求调整合适字体及大小--Unit1One way of summarizing the American position is to state that we value originality and independence more than the Chinese do. The contrast between our two cultures can also be seen in terms of the fears we both harbor. Chinese teachers are fearful that if skills are not acquired early, they may never be acquired; there is, on the other hand, no comparable hurry to promote creativity. American educators fear that unless creativity has been acquired early, it may never emerge; on the other hand, skills can be picked up later.However, I do not want to overstate my case. There is enormous creativity to be found in Chinese scientific, technological and artistic innovations past and present. And there is a danger of exaggerating creative breakthroughs in the West. When any innovation is examined closely, its reliance on previous achievements is all too apparent (the "standing on the shoulders of giants" phenomenon).But assuming that the contrast I have developed is valid, and that the fostering of skills and creativity are both worthwhile goals, the important question becomes this: Can we gather, from the Chinese and American extremes, a superior way to approach education, perhaps striking a better balance between the poles of creativity and basic skillsUnit2Walton set up a college scholarship fund for employees' children, a disaster relief fund to rebuild employee homes damaged by fires, floods, tornadoes, and the like. He believed in cultivating ideas and rewarding success."He'd say, 'That fellow worked hard, let's give him a little extra,'" recalls retired president Ferold F. Arend, who was stunned at such generosity after the stingy employer he left to join Wal-Mart. "I had to change my way of thinking when I came aboard.""The reason for our success," says Walton, in a company handout, "is our people and the way they're treated and the way they feel about their company. They believe things are different here, but they deserve the credit."Adds company lawyer Jim Hendren: "I've never seen anyone yet who worked for him or was around him for any length of time who wasn't better off. And I don't mean just financially, although a lot of people are. It's just something about him -- coming into contact with Sam Walton just makes you a better person."Making the journey from log cabin to White House is part of the American Dream. But when Jimmy Carter was defeated in his attempt to gain a second term as President of the United States he found himself suddenly thrown out of the White House and back in his log cabin. This is how he coped.Unit3SEAN: If that sort of thing happened only once in a while, it wouldn't be so bad. Overall, I wouldn't want to trade my dad for anyone else's. He loves us kids and Mom too. But I think that's sometimes the problem. He wants to do things for us, things he thinks are good. But he needs to give them more thought because: SEAN, HEIDI and DIANE: (In unison) Father knows better!(The lights quickly fade to black and then come up a second or two later. DIANE stands alone at the Down Right edge of the stage. HEIDI and SEAN enter Down Left and cross to the edge of the stage. ) DIANE: Can you imagine how humiliated I was An honor student, class president. And Father was out asking people to have their sons call and ask me to the prom! But that's dear old dad. Actually, he is a dear. He just doesn't stop to think. And it's not just one of us who've felt the heavy hand of interference. Oh, no, all three of us live in constant dread knowing that at any time disaster can strike because: Father knows better.Unit4I'd never realized how important daily routine is: dressing for work, sleeping normal hours. I'd never thought I relied so much on co-workers for company. I began to understand why long-term unemployment can be so damaging, why life without an externally supported daily plan can lead to higher rates of drug abuse, crime, suicide.To restore balance to my life, I force myself back into the real world. I call people, arrange to meet with the few remaining friends who haven't fled New York City. I try to at least get to the gym, so as to set apart the weekend from the rest of my week. I arrangeinterviews for stories, doctor's appointments -- anything to get me out of the house and connected with others.But sometimes being face to face is too much. I see a friend and her ringing laughter is intolerable -- the noise of conversation in the restaurant, unbearable. I make my excuses and flee. I re-enter my apartment and run to the computer as though it were a place of safety.I click on the modem, the once-annoying sound of the connection now as pleasant as my favorite tune. I enter my password. The real world disappears.Thought you were safe sharing secrets with Internet friends Wait for the doorbell...Unit5The runway felt different this time. It startled him for a brief moment. Then it all hit him like a wet bale of hay. The bar was set at nine inches higher than his personal best. That's only one inch off the National record, he thought. The intensity of the moment filled his mind with anxiety. He began shaking the tension. It wasn't working. He became more tense. Why was this happening to him now, he thought. He began to get nervous. Afraid would be a more accurate description. What was he going to do He had never experienced these feelings. Then out of nowhere, and from the deepest depths of his soul, he pictured his mother. Why now What was his mother doing in his thoughts at a time like this It was simple.His mother always used to tell him when you felt tense, anxious or even scared, take deep breaths.So he did. Along with shaking the tension from his legs, he gently laid his pole at his feet. He began to stretch out his arms and upper body. The light breeze that was once there was now gone. He carefully picked up his pole. He felt his heart pounding. He was sure the crowd did, too. The silence was deafening. When he heard the singing of some distant birds in flight, he knew it was his time to fly.Unit6Racing the clock every day is such an exhausting effort that when I actually have a few free moments, I tend to collapse. Mostly I sink into a chair and stare into space while I imagine how lovely life would be if only I possessed the organizational skills and the energy of my superheroines. In fact, I waste a good deal of my spare time just worrying about what other women are accomplishing in theirs. Sometimes I think that these modern fairy tales create as many problems for women as the old stories that had us biding our time for the day our prince would come.Yet superwomen tales continue to charm me. Despite my friend's warning against being taken in, despite everything I've learned, I find that I'm not only willing, but positively eager to buy that bridge she mentioned. Why I suppose it has something to do with the appeal of an optimistic approach to life -- and the fact that extraordinary deeds have been accomplished by determinedindividuals who refused to believe that "you can't" was the final word on their dreams.Men have generally been assured that achieving their heart's desires would be a piece of cake. Women, of course, have always believed that we can't have our cake and eat it too-the old low-dream diet. Perhaps becoming a superwoman is an impossible dream for me, but life without that kind of fantasy is as unappealing as a diet with no treats.1) The young woman described to the policemen the way the man ran up to her and grabbed the bag from her hand.2) All the people working for Sam Walton admire the way he manages Wal-Mart and the way he treats his employees.3) The neighbors were disgusted at the way he talked to his old father.4) It's amazing the way the eight-year-old boy managed to stay so calm when he faced the emergency.1. You will find yourself penniless in a month.2. He found himself lying in a hospital ward.3. She found herself faced with the toughest job she had ever taken.4. Susan found herself in a trap from which she could not escape.1) Obviously what the speaker wanted to emphasize was the impact of these findings rather than the process that led to these findings.2) It seems that he is never bothered about what people would think about his behavior.3) The CEO never hesitates to let his employees know what he is planning for the company.4) The scientist will show the audience what a tele-operated robot can do for a family.5)Despite all this she manages to get her act together.1、She herself believed in freedom,so much so that she would rather die than live without it.2、Assuming the proposal is accepted,where are we going to get the money?3、Only by rewarding success can you bring out the best in your employess.4、It’s amazing the eight-year-old boy managed to stay so calm when he faced the emergency.5、Allen should have known better than to lend such a large sum of money to that untrustworthy cousin of his.。

How to Handle the StressNowadays more and more people have been under various stresses and there has been an increase in stress-related diseases among employees and students. This phenomenon has aroused immediate concern and widespread discussion among the general public. From my perspective, the resources of stresses can be from our work, family and also from the society, and learning how to deal with stresses has far-reaching significance to our body health.As a matter of fact, some solutions to reduce stresses can be illustrated below. The first one that comes to my mind readily is to share our stress with others. It can be enormously helpful because we may feel quite relaxed after talking to others and things even turn better if we get any valuable suggestions from them. What’s more, making time for fun such as listening to music and watching movies may be good medicine. Additionally, it is also a great way to reduce anxiety to do a large number of physical activities.From what has been discussed above, I strongly believe that we should know how to reduce enormous stress because it poses a general threat to human body health. As a common employee, I often feel immense stress at work. In those cases, I always tried to talk with my close friends to hear their advice or just listen to my favorite music. Only by having both mental and physical health can we hope to do our job well in the future?My favorite way of keeping fitsObservations and research findings indicate that people are increasingly concerned abo ut keeping fits. The importance people attach to it and the rapid development of related s ervices are the signs of this.There are several ways of keeping fits. Dieting should be fundamental to one’s heal th. We are facing more choice than ever before. Therefore, we should be cautious to sele ct the proper foods and to control the reasonable amount. What’s more, taking experienc e is another essential way. In addition, nobody is exposed to be considered as healthy in mental disorder, so that keeping mental health is also important.As for me, I am exerting all my strength on keeping my fits, by taking reasonable di eting and proper exercise and by remaining in good mind. In particular, I like jogging, m ore than four times per week, and approximately ．Nowadays, more and more people are concerned about the problem of environmental protection, for the pollution has brought us so many bad influences. It is important for us to r ealize that it is everyone’s duty to protect our environment.To cope with this nation-wide problem, our government has started to take a series of effective measures. The most effective way is to save energy and reduce carbon emission. Because every year billions of tons of carbon dioxide are emitted into the air, which in part, result in the global warming and climate changing.For me, I am trying to make my own contributions. Firstly, I go to work by bus instead of driving. Secondly, I am getting to form the habit of saving water and electricity. For example, when I brush my teeth and wash my hands, I will never leave the water running again. What's more, I even recommend our relatives and friends to do so. By now my ways have been working perfectly and efficiently.Nowadays,with the rapid development of computer technology,in particular,the artifici al intelligence(AI),the application of senior AI in the future has aroused a considerable world-wide concern.It is recently reported that in a ground-breaking fight between man and AI,the world champion of game Go was mercilessly de feated by Deep Mind Alpha Go,a product from Google,which gives rise to some people ’s fear toward advanced AI in future practice.And they take it for granted that human being would probably be totally controlled by machine.As far as AI is concerned,I am fully convinced that we are supposed to maintain an obje ctive and positive attitude toward the emerging issue of artificial intelligence.It is know n to all that AI is nothing but the simulation of information on the process of conscious thinking,or in another words,it’s something that subjects to its inventor’s design awaren ess.Consequently,as long as we are fully conscious of its possible disadvantages,certai n restrictions can be input into the program to avoid potential disastrous occurrences.Ad ditionally,it is well hoped that AI and intelligent machines can possibly free human labo rs from virtually all kinds of jobs.In that case/Above-mentioned discussion can safely lead to the conclusion that what we are supposed to do i s but to learn to get along with the inevitable development of computer technology and t o adapt to the updated social structure changed by AI.What make happy couple happy?With the rapid development of modem society,an increasing number of people are c oncerned about the problem of the relationship between a husband and wife in our societ y.Not only the government but also the public have to pay more attention tothis phenomenon .Undoubtedly,it has brought about a great influence on people's work and living. Based on what has been discussed so far,it follows that some eflective solutions should be found to deal with the problem of the relationship between two people.On the one ha nd,the couples had better understand each other's daily habits so that they can form the s ame interests,which can make couples become happy on the other hand,no matter how close the relationship is between two people,we should give enough room to each other because keeping appropriate distance can make the two people more comfortable.Only in these ways can we solve this problem successfully and eficctivcly.As far as I am concerned,no relationship will be free of difficulty or conflict.That happ y couples live happily is because that they are able to both apologize and forgive facing with difficulty or conflict.。

你知道雅思听力的评分标准是什么吗雅思听力怎么计算分数雅思听力评分标准：雅思索试听力A类与G类是一样的，所以雅思听力考试评分标准也是相同的：答对10-12道，得4分答对13-15道，得4.5分答对16-19道，得5分答对20-22道，得5.5分答对23-26道，得6分答对27-29道，得6.5分答对30-32道，得7分答对33-34道，得7.5分答对35-37道，得8分答对38-39道，得8.5分答对40道，得9分雅思听力配对题的解题技巧心得要把握雅思听力配对题技巧，我们先来看下雅思听力配对题的主要形式：1.地图配对。
地图配对这种形式相对比较简洁，同义转换很少消失，只要跟着讲解地图的思路走，不弄错方向就不会有太大的问题。
通常这种类型的题目会消失在section 1和section 2的参观旅游场景中，要求考生把地图中标注的字母和题目要求找到的地点对应起来。
虽然选项数量较多，但题目很少消失同义转换，定位还是很简洁的。
2.文字配对题则又可以分为两类：(1)选项多于题干型：这类考题的选项一般是对题干进行解释说明，很简单消失同义转换。
而且有些选项会比较相像，干扰性强。
考生在审题时应明确题干的中心词，弄清问的是什么，为定位作好预备。
另外，要快速扫瞄选项，记住大致意思，以免听到了答案却找不到选项，影响听题节奏。
(2)题干多于选项型：这类考题类似于把题干进行分类，一般选项为三个，需要重复使用。
在考试中这种形式的考题通常是给出对某些事物的不同看法，依据说话人的表述作出选择。
由于选项相对固定，考生要重点分析题干中的信息，避开由于题干同义转换带来的定位困难。
另外说话人的语气和态度也能关心我们作出选择，有时题目考的就是他们的言下之意，光听懂字面意思还不够。

– reemit energy as infrared rays.
29
• What happens to the infrared rays that are reemitted into the atmosphere?
• The solar radiation least absorbed by the layers of the atmosphere before reaching Earth is visible light.
22
• What happens to solar energy that reaches Earth’s surface?
– greenhouse effect
33
• The warming of the surface and lower atmosphere of Earth that occurs when carbon dioxide, water vapor, and other gases in the air absorb and reradiate infrared radiation is called the _________.
– air comes into direct contact with Earth.
• What is the primary cause of the heating of the lower atmosphere?
– The distribution of heat through the troposphere by convection. – What is convection?
– greenhouse effect.
52
• The transfer of energy as heat from one substance to another by direct contact is called
– conduction.
55
• Conduction heats only the lowest few centimeters of the atmosphere because
– Absorption of the sun’s rays by gases in the atmosphere. – Ocean and land surfaces absorb energy and then give off that energy as heat.
Matching
3. radiation 4. wavelength 5. electromagnetic waves 6. electromagnetic spectrum
– it is either absorbed or reflected.
24
• What is the fraction of solar radiation that is reflected off a particular surface called?
– Albedo
26
• Solar radiation that is not reflected is
– absorbed.
27
• When Earth’s surface absorbs solar radiation, the surface materials are heated by
– short-wavelength infrared rays and visible light.
28
Chapter 22 Section 2 Handout
Solar Energy and the Atmosphere
1
• How is Earth’s atmosphere heated?
– By the transfer of energy from the sun.
2
• Name the two primary sources of heat in the atmosphere.
• Convection is movement of matter due to differences in density caused by temperature variations.
The End
– Longer:
• infrared rays • radio rays
17
• How much of the radiation from visible light waves is absorbed as they pass through the atmosphere?
– a small amount
7
• What form of radiation can humans see?
– visible light
11
• Which wavelengths are shorter than visible light? Which are longer?
– Shorter:
• ultraviolet rays • x rays • gamma rays
a. the waves that make up all forms of radiation b. the distance from any point on a wave to the identical point on the next wave c. all of the frequencies or wavelengths of electromagnetic radiation d. all forms of energy that travel through space as waves, including the energy that Earth receives from the sun
– Gas molecules in the atmosphere, such as water vapor and carbon dioxide, absorb the infrared rays.
32
• One process that helps heat Earth’s atmosphere that is similar to the process that heats a greenhouse is called the _________.
