Unit 6-Conversation 1

Janet: What are you reading, Kate?

Kate:Alice in Wonderland, by Lewis Carroll. Do you know it?

Janet: I've heard of it, yes, but I've never read it. It's a 19th century children's story, isn't it?

K a te: That's right. It's very famous. It's set in Oxford. It starts with this young girl sitting on a river bank. The interesting thing is, the author, Lewis Carroll, he was an Oxford professor and he used to have tea with the girl's family on this river bank.

Ja net: Oh, that's fascinating! I'll put it into my diary. Kate: Is that what you're writing? I know you've been keeping a diary all the year.

Janet: It's been a great year. I've had such a good time — so lucky to have Mark and Kate as friends. Feel I've been doing well with work. Much happier about asking questions in tutorials.

Janet: My screen's gone dark.

Mark: You're using the battery, remember. It's run out, obviously.

Janet: It can't be the battery. It's still charged. Oh no it's still black. Oh dear, I hope it's nothing serious. I haven't backed anything up recently.

Kate: That's not like you, Janet.

Janet:I know, but I lost my memory stick. I really should have backed things up. How stupid of me not to do that! Supposing I've lost everything!

Mark: Let me take a look. The power is still on. And also the operating system still seems to be working ... I think it has to be the graphics card ... But maybe that's not the problem ... Janet: If only I'd backed things up!

Kate: Relax, Janet! We'll take it to the computer shop this afternoon. I'm sure it'll be OK.

Janet: I hope so.

Unit 6-Conversation 2

Janet: Tell me about Alice in Wonderland.

Kate: I tell you what, I'll read it to you.

Kate: Alice was beginning to get very tired of sitting by her sister on the bank and having nothing to do: Once or twice, she had peeped into the book her sister was reading, but it had no pictures or conversations in it, "and what is the use of a book," thought Alice, "without pictures or conversation?" So she was considering in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid) ... Janet: Kate, Mark, where are you going? You've got my laptop!

Kate: It's all right, Janet, we're taking it to the computer shop. We'll be back soon.

Mark: It's not like Janet to forget to back up her work. Kate: She should have been more careful. Janet: It was stupid of me, I know! Stupid, stupid! Janet: Oh! It was a dream! What a relief!

Kate: You were talking in your sleep.

Janet: What was I saying?

Kate: "Stupid, stupid."

M ark:I've sorted out your computer.

Janet: Have you? Oh, thank goodness! What was the problem?

Mark:It was the graphics card, as I predicted ...

Janet: Is that what it was! I'm so relieved! Thanks, Mark. Kate: He's great, isn't he?

Janet: Yes. So are you, Kate.

Kate: You're such a good friend.

Unit 6-Outside view

Computers are a very important part of our lives. They tell us about delays to transport. They drive trains, analyze evidence and control buildings. Did you know that 60 per cent of homes in Britain have got a PC (a personal computer)? For many young people, playing computer games is their favorite way of spending spare time. Computers are a very important part of most areas of life in Britain-libraries, the police and in school. But they are becoming more important in our homes as well. They’ll even control the way we live-in “smart homes”or computer-controlled houses. The smart home is now a real possibility. It will become very common. A central computer will adjust the temperature, act as a burglar alarm and switch on lights, ready for you to come back home. And of course you will be able to give new instructions to the computer from your mobile phone. So if your plans change, your home will react to match. Many homes have got lots of televisions and several computers. The smart home will provide TV and Internet sockets in every room, so you’ll be able to do what you want whenever you want. If the temperature outside changes, the smart home will adjust the temperature levels inside. The computer will also close the blinds when it gets dark or to stop so much sun from entering a room. And if you want to eat when you get home, the computer will turn the oven on for you! Are computers taking over our lives? In a survey, 44 per cent of young people between 11 and 16 said their PC was a trusted friend. Twenty per cent said they were happier at their computer than spending time with family or friends. Another survey found that people in Britain spend so much time on the phone, texting and reading emails that they no longer have time for conversation. What do you think about that?

Unit 6-Listening in

News Report

US Scientists have announced the discovery of gravitational waves, which are tiny waves produced by massive objects

moving very quickly. Two black holes produced the waves when they crashed into each other about 1.3 billion years ago.

A black hole is a place in space where the gravity is so strong that even light cannot escape. This announcement of the discovery comes a century after Albert Einstein first predicted gravitational waves would exist.

The discovery was made possible by using a highly sensitive instrument designed to detect signals of gravitational waves and identify their sources. This discovery proves that there are gravitational waves, and strongly confirms the existence of black holes.

With this discovery, scientists are given a new tool to study and understand the universe. The waves could help scientists learn more about what happened immediately after the universe began and how the universe expanded. Scientists hope that they may be able to observe parts of the universe that were previously undetectable.

1.What discovery have US scientists made?

2.What features do black holes have according to the news

report?

3.Why is the discovery important?

Passage 1

When you have a biscuit with your cup of tea, do you dunk it? And if so, what’s the perfect way to do it? That’s the subject of today’s Science in Action report. It may be hard to believe but scientists at the University of Bristol have been analyzing this question. And after a two-month study they devised a mathematical formula for dunking biscuits. So no more melting chocolate, or biscuit crumbs in the bottom of your cup, which is the fate of one in four biscuits that are dunked in tea, according to research by a biscuit manufacturer. Doughnut dunkers don’t face the same problems because doughnuts are held together with an elastic net of protein, gluten. This substance allows the doughnut to absorb liquid without breaking down its structure. The structure of a biscuit, however, is held together by sugar which melts when placed in hot tea or coffee.

So what is the answer? The researcher, let by Dr. Len Fisher, discovered that holding the biscuit in a horizontal position – or “flat-on”– has a significant effect on the amount of time that a biscuit can stay in hot liquid before falling apart. In fact this horizontal dunking results in a dunking time up to four times longer than traditional vertical dunking.

What’s the reason for this? It seems that the answer is related to diffusion, in other words, the length of time it takes for the liquid to penetrate the structure of the biscuit. Basically, it takes longer for the liquid to travel through the channels of a biscuit when it is laid flat on the surface of the liquid. Also the fact that when a biscuit is dunked horizontally, with the biscuit submerged in the liquid, and the chocolate coating staying out of the liquid, the chocolate helps hold the biscuit together. Another factor influencing the equation is the temperature of the tea – the hotter the tea, the faster the sugar melts.

Researchers also found that by dunking a biscuit into tea or coffee, up to ten times more flavor is release than it the biscuit is eaten dry. So it’s worth experimenting yourself. If you are wondering how you can perfect the horizontal dunk, the researchers have come up with an idea for a biscuit-holding device to make dunking biscuits easier. They are even mow working on producing a table giving guidelines on dunking times for different types of biscuit. On that note, I think it’s time to go off to the canteen for a tea break! Passage 2

Peter: Hey Louise, look at this book about crop circles - some of the photos are absolutely unbelievable. Louise: You don t believe in all that stuff, do you Peter? Peter: I'm not saying I believe in UFOs and things, but some of the formations are fascinating. They’re

made up of lots of interconnected circles and

geometrical shapes. You know, in the past few years,

there have been more reports of them. The circles

are getting larger and the designs are getting more

intricate... I'm sure that they can't all be man-made.

Think about it - they're so complicated, and they

appear at night in the middle of fields of wheat

barley or corn. It’s definitely pretty weird! Louise: I know, but l saw a TV documentary about it, and they showed how a group of hoaxers made an

elaborate crop circle in a field at night using

wooden plank, ropes, plastic tubes and a garden

roller. They even fooled some of the people who

believe in the paranormal-aliens coming down in

UFOs and aliens coming down in UFOs and

creating them, and so on.

Peter: I'm sure lots of them are created by people just to get publicity but look here-it says, “The first

records of crop circles go back as far as the 17th

century. Since the 1970s there have been over

12,000 reports from countries all around the world

including Italy, America, South Africa, Australia

and Brazil.” Most reports are from here in England

though.

Louise: But surely that’s just because they get so much

media coverage these days, so more people are

making them.

Peter: Perhaps, but how do you explain the fact that the actual chemical composition of the grains of corps

inside the circles changes? Scientific tests have

found they have a higher protein level. The stems of

the grains have often been exposed to high

temperatures. And they found that the soil within

the circles contains more iron than the soil outside.

So far, the hoaxers haven't been able to copy all

these features.

Louise: Well, I'm not a scientist but I'm pretty sceptical about all these so-called paranormal explanations. I

remember in the programme I watched, the

researchers found signs of human interference, such

as holes in the earth and footprints!

Peter: Come on… you must admit, that still leaves a lot which is unexplained!

Louise: There's lots of things that are hard to explain but this really...

大学英语自学教程(上册) unit 23 非言语交际

大学英语自学教程(上册) unit 23 非言语交际 23-A. Non-verbal Communication If anyone asked you what were the main means of communication between people, what would you say? That isn’t a catch question. The answer is simple and obvious. It would almost certainly refer to means of communication that involve the use of words. Speakers and listeners-oral communication, and writers and readers-written communication. And you’d be quite right. There is, however, another form of communication which we all use most of the time, usually without knowing it. This is sometimes called body language. Its more technical name is non-verbal communication. Non-verbal, because it does not involve the use of words. NVC for short. When someone is saying something with which he agrees, the average European will smile and nod approval. On the other hand, if you disagree with what they are saying, you may frown and shake your head. In this way you signal your reactions, and communicate them to the speaker without saying a word. I referred a moment ago to "the average European”, because body language is very much tied to culture, and in order not to misunderstand, or not to be misunderstood, you must realize this. A smiling Chinese, for instance, may not be approving but somewhat embarrassed. Quite a lot of work is now being done on the subject of NVC, which is obviously important, for instance, to managers, who have to deal every day with their staff, and have to understand what other people are feeling if they are to create good working conditions. Body language, or NVC signals, are sometimes categorized into five kinds: 1.body and facial gestures; 2.eye contact; 3.body contact or "proximity"; 4.clothing and physical appearance; and 5.the quality of speech. I expect you understood all those, except perhaps "proximity." This simply means "closeness". In some cultures-and I am sure this is a cultural feature and not an individual one-it is quite normal for people to stand close together, or to more or less thrust their face into yours when they are talking to you. In other cultures, this is disliked; Americans, for instance, talk about invasion of their space. Some signals are probably common to all of us. If a public speaker (like a professor, for example) is all the time fiddling with a pencil, or with his glasses, while he is talking to you, he is telling you quite clearly that he is nervous. A person who holds a hand over his mouth when he is talking is signaling that he is lacking in confidence. If you start wriggling in your chairs, looking secretly at your watches or yawning behind your hands, I shall soon get the message that I’m boring you. And so on. I'm sure you could make a whole list of such signals-and it might be fun if you did. All the signals I have mentioned so far can be controlled. If you are aware that you are doing these things, you can stop. You can even learn to give false signals. Most public speakers are in fact nervous, but a good speaker learns to hide this by giving off signals of confidence. Other kinds of NVC are not so easy to control. Eye contact, for instance. Unless you are confessing intense love, you hardly ever look into someone else’s eyes for very long. If you try it, you’ll find they will soon away, probably in embarrassment.

Don’t you hear Big John is coming?” Task3: A View of Happiness Script Dr. Smith has proposed a reasonable, if perhaps somewhat oversimplifies, view of happiness. According to his theory, happiness might be described as a state if balance. And when human or certain animals achieve that balance, they rend to remain in that condition in order to repeat the happy feeling. To illustrate this, we may study two magnets. When their positive and negative poles meet, they are comfortably joined, and they remain there. In other words, they have attained a balance or state of happiness. If on the other hand, one of the poles is reversed, and positive pole is presses against positive pole, there is resistance, instability, imbalance a state of unhappiness. Animals with some degree of intelligence seem to find happiness in reinforcement. Once they have gained one or more of their goals such as food, and water, they learn to repeat the actions that led to satisfaction of those goals. This repetition or reinforcement produces a state of balance or sense of happiness. According to this theory, only animals with a

How to be a successful language learner? ―Learning a language is easy, even a child can do it!‖ Most adults who are learning a second language would disagree with this statement. For them, learning a language is a very difficult task. They need hundreds of hours of study and practice, and even this will not guarantee success for every adult language learner. Language learning is different from other kinds of learning. Some people who are very intelligent and successful in their fields find it difficult to succeed in language learning. Conversely, some people who are successful language learners find it difficult to succeed in other fields. Language teachers often offer advice to language learners: “Read as much as you can in the new language.”“ Practice speaking the language every day. ”“Live with people who speak the language.”“Don‘t translate-try to think in the new language.”“ Learn as a child would learn; play with the language.” But what does a successful language learner do? Language learning research shows that successful language learners are similar in many ways.

Unit 1 The Perfect Swarm Narrator: Damage from swarms of locusts can reach disastrous proportions. A single swarm of desert locusts can consume over 70,000 metric tons of vegetation a day. There is, however, one continent that’s locust-free: North America. 旁白：蝗虫群的伤害可以达到灾难性的程度。一个单一的沙漠蝗虫可以消耗超过70000吨的植被一天。然而，有一个大陆是蝗虫自由：美国北部。 Interestingly enough, this wasn’t always true. For hundreds of years, the Rocky Mountain locust was a common pest in the American West. Back in the mid-1800s, thousands of pioneers journeyed across the U.S. in search of free land and new opportunities. They settled on the frontier of the western states, and began to farm the land intensively, growing corn and other crops. 有趣的是，这并不总是真实的。几百年来，落基山脉的蝗虫是美国西部的一种常见害虫。早在19世纪中叶，成千上万的先驱者跨越美国在自由的土地和寻找新的机会。他们定居在西部边境，并开始对土地进行集中耕种，种植玉米和其他农作物。 Then, in 1875, out of nowhere, a rare combination of air currents, drought, and basic biology produced the right conditions for an unthinkable event, the worst storm ever recorded, the “perfect swarm.” It cam e over the horizon like a strange, dark cloud. Not millions, not billions, but trillions of insects, sweeping through the land like a living tornado. Those who saw the incredible event and survived never forgot what they witnessed. 然后，在1875，走出无处，一个罕见的组合，空气电流，干旱，和基本生物学产生了正确的条件为一个不可想象的事件，最坏的风暴有史以来，“完美的群”，它在地平线上像一个奇怪的，黑暗的云。不是上百万，不是数十亿，而是数以万亿计的昆虫，像一个活生生的龙卷风席卷过大地。那些看到了令人难以置信的事件，并幸存下来的人从来没有忘记他们见证了什么。 The swarm came together over the state of Texas, and soon moved quickly across the frontier in a huge destructive cloud that was nearly 3,000 kilometers long. The storm spread north towards North Dakota. The locusts eventually went as far west as the Rocky Mountains, leaving a path of devastation and destruction wherever they went. 群聚在德克萨斯州的上空，并很快在一个巨大的破坏性的云，是近3000公里长的边界迅速移动。风暴向北到了北。蝗虫最终在落基山脉的西部，离开了一条破坏性的道路和毁灭的道路。 An account from one person who observed the swarm described the locust storm. The locusts came down from the sky like hail. Frightened people ran screaming into their homes as the locusts’ claws dug into thei r skin and hung upon their clothing. They heard sharp cracks as the insects came underfoot. The large locusts were everywhere, looking with hungry eyes turning this way and that. Their bodies blocked the sun, bringing darkness along with the destruction. 一个来自一个人的帐户，观察到群描述了蝗虫风暴。蝗虫从空中落下如冰雹。当蝗虫的爪子被挖进他们的皮，挂在他们的衣服上时，吓得人们尖叫着进入他们的家里。随着昆虫来踩在脚下他们听到尖锐的裂缝。大蝗虫到处都是，看着饥饿的眼睛转动着这样的方式。他们的身体挡住了太阳，带来了黑暗与毁灭。 Crop damages were absolutely astonishing. If such destruction were to happen today it would cost an estimated US$116 billion, more than the most costly hurricane in American history.
