参考解析
解析：
对话中女士提到如果你想记住某件事，think of a physical thing that reminds you of，她还举例说明：如果想记住黑斯廷斯战争（the Battle of Hastings）发生的时间1066年，可以联想一个标有1066标签的瓶子（bottle）。
【录音原文】
M: Today on mind matters, I’m talking to Dr Ann Winters, an expert on human memory. Ann, welcome to the program. Now, I suppose the first question everyone would ask is: what exactly is human memory?
W: Well, like so many easy questions, the answer isn’t very simple. Basically, human memory is a compartment in people’s brains where they store images rather like the hard disc drive in a computer. And like a hard disc drive, our memories can become infected or even wiped out by accidents. But the comparison breaks down when we consider that we can train our memories to expand and work better which computers can’t manage yet.
M: When you talk about memory being infected, do you mean by a disease?
W: Yes. For instance, people suffering from a physiological disease like Alzheimer: forget things that happened in the past. And they also forget how to perform simple tasks like tying their shoelaces. The good news is that brain exercises can help keep the brain young. Research has shown that people who have better educations and more mentally active jobs have a lower risk of developing the disease.
M: And how can someone exercise his brain? By thinking a lot?
W: In a way, yes. But you can also practice using your memory which not only exercises your brain but also improves you ability to remember things. Unfortunately, a lot of devices in modern life are designed to make sure we don’t t forget things which can make our brains more idle and weaken our memories.
M: Can you give us some examples of how to exercise our memories?
W: Sure, there is a very simple technique, although it works better for some people than for others. When you want to remember something, think of a physical thing it reminds you of. If I want to remember a date from history, let’s say, 1066, the date of the Battle of Hastings. I might think that battle reminds me of bottle, so I think of a bottle with the number 1066 written on the label. And I just picture that bottle to myself.

Passage TwoWhen we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.People who are nearsighted can only see things that are very close to their eyes. Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly'.People who are nearsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object outof the other eye. You will find the object's relation to the background (背景) and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.40. We should take good care of our eyes ______.A. only when we cannot see perfectlyB. only when we can see wellC. even if we can see wellD. only when we realize how important our eyes are

第一篇If your doctor could give you a drug that would let you live a healthy life for twice as long, would you take it?The good news is that we may be drawing near to that date.Scientists have already extended the lives of flies,worms and mice in laboratories. Many now think that using genetic treatments we will soon be able to extend human life to at least 140 years.This seems a great idea. Think of how much more time we could spend chasing our dreams,spending time with our loved ones,watching our families grow and have families of their own."Longer life would give us a chance to recover from our mistakes and promote long term thinking,"says Dr Gregory Stock of the University of California School of Public Health."It would also raise productivity by adding to the year we can work."Longer lives don't just affect the people who live them. They also affect society as a whole. "We have war,poverty,all sorts of issues around,and I don't think any of them would be at all helped by having people live longer,"says US bioethicist Daniel Callahan,"The question is what we will get as a society?I suspect it won't be a better society."It would certainly be a very different society. People are already finding it more difficult to stay married. Divorce rates are rising. What would happen to marriage in a society where people lived for 140 years? And what would happen to family life if 9 or 10 generations of the same family were all alive at the same time?Research into ageing may enable women to remain fertile for longer. And that raises the prospect of having 100-year-old parents,or brothers and sisters born 50 years apart. We think of an elder sibling as someone who can protect us and offer help and advice. That would be hard to do if that sibling came from a completely different generation.Working life would also be affected,especially if the retirement age was lifted.More people would stay in work for longer. That would give us the benefits of age一skill,wisdom and good judgment.On the other hand,more people working for longer would create greater competition for jobs. It would make it more difficult for younger people to find a job. Top posts would be dominated by the same few individuals,making career progress more difficult. And how easily would a 25-year-old employee be able to communicate with a 125-year-old boss?Young people would be a smaller part of a society in which people lived to 140.It may be that such a society would place less importance on guiding and educating young people,and more on making life comfortable for the old.And society would feel very different if more of its members were older. There would be more wisdom,but less energy.Young people like to move about. Old people like to sit still.Young people tend to act without thinking.Old people tend to think without acting.Young people are curious and like to experience different things.Old people are less enthusiastic about change.In fact,they are less enthusiastic about everything.The effect of anti-ageing technology is deeper than we might think.But as the science advances,we need to think about these changes now."If this could ever happen,then we'd better ask what kind of society we want to get,"says Daniel Callahan."We had better not go anywhere near it until we have figure those problems out."Which of the following is implied in the fifth paragraph?A:Marriages in the US today are quite unstable.B:More and more people in the US today want to get married.C:Living longer would make it easier for people to maintain their marital ties.D:If people live longer,they would stay in marriage longer.

In Your FaceWhy is this man so angry?We don't know the reason,but we can see the emotion in his face.What- ever culture you come from,you can understand the feeling that he is expressing.Forty years ago,psychologist Paul Ekman of the University of California,San Francisco,became interested in how people's faces show their feelings.He took photographs of Americans expressing various emotions.Then he showed them to the Fore people,who live in the jungle in New Guinea. Most of the Fore had never seen foreign faces,but they easily understood Americans' expressions of anger,happiness,sad- ness,disgust,fear,and surprise.Then Ekman did the same experiment in reverse.He showed pictures of Fore faces to Americans,and the results were similar. Americans had no problems reading the emotions on the Fore people's faces. Ekman's research gave powerful support to the theory that facial expressions for basic emotions are the same everywhere.He did more research in Japan,Brazil,and Argentina,and got the same results.According to Ekman,these six emotions are universal because they are built into our brains.Theydeveloped to help us deal with things quickly that might hurt us.Some emotional triggers are universal as well.When something suddenly comes into sight,people feel fear,because it might be dangerous.But most emotional triggers are learned.For example,two people might smell newly cut grass.One person spent won- derful summers in the country as a child,so the smell makes him happy.The other person remembers work- ing very hard on a farm and being hungry,so he feels sad.Once we make an emotional association in our brain,it is difficult,and sometimes impossible,to change it."Emotion is the least changeable part of the brain,"says Ekman.But we can learn to manage our emotions better. For instance,we can be more aware of things that make us angry,and we can think before we react.There are many differences between cultures,in their languages and customs.But a smile is exactly the same everywhere.Americans get angry more often than the Fore people from New Guinea.A:RightB:WrongC:Not mentioned

Improve Your MemoryTo many people advancing age means losing your hair,your waistline and your memory.But is it an inescapable fact that the older you get,the less you remember? Well,as time goes by,we tend to blame age for problems that are not necessarily age-related.When a teenager can't find her keys,she thinks it's because she's distracted or disorganized, but a 70-year-old blames her memory. In fact,the 70-year-old may have been misplacing things for decades一like we all do from time to time.In healthy people,memory doesn't deteriorate as quickly as many of us think. According to psychologists,as we age,our memory mechanism isn't broken,it's just different.The brain's processing time slows down over the years,though no one knows exactly why.Recent research suggests that nerve cells lose efficiency and that there's less activity in the part of the brain that decides whether to store information or not.But it's not clear that less activity is worse.A beginning athlete is winded. more easily than a trained athlete.In the same way,as the brain gets more skilled at a task,it spends less energy on it.There are steps you can take to improve your memory,though you have to work to keep your brain in shape.It's like having a good body. You can't go to the gym once a year and expect to stay in top form.Some memory enhancement experts suggest using the AM principle.Pay attention to what you want to remember. Then give some meaning to it. We remember things when we focus on them, whether we intend to or not. That helps explain why jingles stick in our minds.They are played on loud,flashy TV commercials.They also use rhyme and music to help us remember better.Basic organization helps us remember the boring stuff. For example,rather than trying to recall a random list of groceries,we can divide them into categories,such as dairy,meat and produce. For important things like keys and money,we can set up a"forget-me-not"spot where we always keep them.We can also eat to aid our memory power. Whole grains,fruits and vegetables are excellent sources of glucose,the brain's preferred fuel. Another low-tech way to improve memory is to get adequate rest. Sleep may allow our brain time to encode memories.Interest in friends,family and hobbies does wonders for our memory.A sense of passion or purpose helps us remember. Memory requires us to pay attention to our lives,allowing us to discover in them everything worth remembering.As we get older, our memory mechanism is broken,and so cannot be the same as it was before.A:Right B:Wrong C:Not mentioned

It's almost impossible to go through life without experiencing some kind of failure.People who do so probably live so cautiously that they go nowhere.Put simply,they’re not real living at all.But,the wonderful thing about failure is that it's entirely up to us to decide how to look at it.We can choose to see failure as"the end of the world,"or as proof of just how inadequate we are.Or,we can look at failure as the incredible learning experience that it often is.Every time we fail at something,we can choose to look for the lesson we're meant to learn.These lessons are very important;they're how we grow,and how we keep from making that same mistake again.Failures stop us only if we let them.Failure can also teach us things about ourselves that we would never have learned otherwise.For instance,failure can help you discover how strong a person you are.Failing at something can help you discover your truest friends,or help you find unexpected motivation to succeed.

Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism. This，too，can be corrected by glasses. Some people’s eyes become cloudy because of cataracts. Long ago these people often became blind. Now，however，it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself，look at an object out of one eye；Then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.
When things far away seem indistinct， one is probably______.A.astigmatic
B.far-sighted
C.suffering from cataracts
D.near-sighted

The Need to RememberSome people say they have no memory at all:"I just can't remember a thing!"But of course we all have a memory.Our memory tells us who we are.Our memory helps us to make use in the present of what we have learnt in the past.In fact we have different types of memory.For example,our visual memory helps us recall facts and places.Some people have such a strong visual memory that they can remember exactly what they have seen,for example,pages of a book,as a complete picture.Our verbal（言语的）memory helps us remember words and figures we may have heard but not seen or written:Items of a shopping list,a chemical formula,dates,or a recipe.With our emotional（情感的）memory, we recall situations or places where we had; strong feelings,perhaps of happiness or unhappiness. We also have special memories for smell,taste, touch and sound,and for performing physical movements.We have two ways of storing any of these memories. Our short-term memory stores items for up to thirty seconds-enough to remember a telephone number while we dial.Our long-term mem-ory,on the other hand,may store items for a lifetime. Older people in fact have a much biter long-term memory than short-term .They may forget what they have done only a few hours ago,but have the clearest remembrance（记忆）of when they were very young.Psychologists tell us that we only remember a few facts about our past,and that we invent the rest. It is as though we remember only the outline of a story.We then make up the details. We of-ten do this in the way we want to remember them,usually so that we appear as the heroes of our own past , or maybe victims needing sympathy（同情）.Emotional memory is used when we perform physical movements.A: RightB: WrongC: Not mentioned

All but the tiniest of roads have to have names so they can be recognized on a map,and so people can ask?directions to them.Americans name a lot of bridges,too.
Very often these names carry a clear geographical reference the Pennsylvania Turnpike,for example.Or,like?the George Washington Bridge,roads and bridges are named for famous historical figures or powerful officers.
We make a big deal out of naming things,as when someone decided to name an airport after a U.S.judge.So?now we have the Baltimore Washington International Thurgood Marshall Airport.
Many,if not most,of our college buildings are named for wealthy people who gave a lot of money to the?schools.And our sports centers took this idea a step further.Companies paid a whole lot of money for what′s called?the"naming rights"to U.S.Cellular Field in Chicago,for example,and Citizens Bank Park in Philadelphia.
Now the governor（州长）of Virginia,Bob McDonnell,wants to sell naming rights to roads and bridges in the state.He says not just companies,but also wealthy people,would help the Virginia transportation budget（预算）by paying to have their names--or perhaps those of loved ones--placed on roads and bridges,and thus on maps as well.
People hold different views,however.Supporters say Americans are used to having things sponsored（赞助）.
Others disagree,considering the idea as the next step in the"companies of America."They wonder how far such an?idea might spread,and where it would end:at the Burger King Pacific Ocean,perhaps.
Most of the roads need to have names so that__________.A.they can remind people of the past
B.people can learn about them better
C.they can be easily recognized on maps
D.people can enjoy naming them
