All that we really need to plot out the future of our universe are a few good measurements

. This does not mean that we can sit down today and outline the future course of the universe with anything like certainty. There are still too many things we don't know about the way the universe is put together. But we do know exacdy what information we need to fill in our knowledge, and we have a pretty good idea of how to go about getting it. Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard(调车场). All of the switches(转辙器) are set before the train arrives, so that its path is completely determined. Some switches we can see, others we cannot. There is no ambiguity if we can see the setting of a switch; we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.

When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.

According to the passage, it is difficult to be certain about the distant future of the universe because we______.

A.have too many conflicting theories

B.do not have enough funding to continue our research

C.are not sure how the universe is put together

D.have focused our investigations on the moon and planets

Passage TwoHow men first learned to invent words is unknown. All we really know is that me

Passage Two

How men first learned to invent words is unknown. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words.

The power of words, then, lies in their associations--the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the happy and sad events of our past; the more we read and learn, the larger the number of words that mean something to us becomes.

Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and feelings. This attractive use of words is what we call literary style. Above all, the real poet is a master of words. He can express his meaning in words which sing like music, and, by their position and association, can move men to tears. We should therefore learn to choose our words carefully and use them correctly, or they will make our speech dull and silly.

Which of the following did men invent first?

A.Words.

B.Sounds.

C.Signs.

D.Letters.

We can make mistakes at any age. Some mistakes we make are about money. But most mistakes
are about people. "Did Jerry really care when I broke up with Helen? .... When I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck?" When we look back, doubts like these can make us feel bad. But when we look back, it' s too late.

Why do we go wrong about our friends or our enemies? Sometimes what people say hides their real meaning. And if we don' t really listen closely we miss the feeling behind the words. Suppose someone tells you, "You' re a lucky dog." That' s being friendly. But "lucky dog?" There' s a bit of envy in those words. Maybe he doesn' t see it himself. But bringing in the "dog" puts you down a little. What he may be saying is that he doesn' t think you deserve your luck.

"Just think of all the things you have to be thankful for is another noise that says one thing and means another. It could mean that the speaker is trying to get you to see your problem as part of your life as a whole. But is he? Wrapped up in this phrase is the thought that your problem isn' t important. It' s telling you to think of all the starving people in the world when you haven't got a date for Saturday night.

How can you tell the real meaning behind someone' s words? One way is to take a good look at the person talking. Do his words fit the way he looks? Does what he says agree with the tone of voice? His posture? The look in his eyes? Stop and think. The minute you spend thinking about the real meaning of what people say to you may save another mistake.

This passage is mainly about ______.

A.how to interpret what people say

B.what to do when. you listen to others talking

C.how to avoid mistakes when you communicate with people

D.why we go wrong with people sometimes

M: Not too bad, thank you Ann. How did you get on in the exams?

M: I haven't got any plan yet. I don't really have enough money to fly home. I suppose I could get a part-time job and earn some money, but I don't really want to. Then again, maybe I could start studying for next semester.

W: Well, I thought about doing some summer courses, but I decided that's not a good idea. I need to do something completely different. You do too. Why don't you join me with my friends on the camping trip?

M: Well, I don't know really. Would your friends mind?

Education is not an end, but a means to an end. In other words, we do not educate children
only for the purpose of educating them; our purpose is to prepare them for life. As soon as we realize this fact, we will understand that it is very important to choose a system of education which will really prepare children for life. It is not enough just to choose the first system of education one finds, or to continue with one's old system of enducation without examining it to see whether it is in fact suitable or not.

In many modem countries it has for some time been fashionable to think that, by free education for all-whether rich or poor, clever or stupid--one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they consider" low" work; and, in fact, work with the hands is thought to be dirty and shameful in such countries.

But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor, We can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we would have terrible diseases in our towns. In countries where there are no servants because everyone is ashamed to do such work, scientists have to waste much of their time doing housework.

In fact, when we say that all of us must be educated to prepare for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability and, secondly, that we can realize that all jobs are necessary to society, and it is very bad to be ashamed of one's work, or to scorn someone else's. Only such a type of education can be called valuable to society.

Education is ______.

A.a means

B.a purpose

C.fashionable

D.the first system

Massive changes in all of the world's deeply cherished sporting habits are underway. Wheth
er it's one of London's parks full of people playing softball,and Russians taking up rugby(橄榄球), or the Superbowl rivaling the British Football Cup Final as a televised spectator event in Britain, the patterns of players and spectators are changing beyond recognition. We are witnessing a globalization of our sporting culture.

That annual bicycle race, the Tour de France, much loved by the French is a good case in point. Just a few years back it was a strictly continental affair with France, Belgium and Holland, Spain and Italy taking part. But in recent years it has been dominated by Colombian mountain climbers, and American and Irish riders.

The people who really matter welcome the shift toward globalization. Peugeot, Michelin and Panasonic are multi-national corporations that want worldwide returns for the millions they invest in teams.' So it does them literally a world of good to see this unofficial world championship become just that.

This is undoubtedly an economic-based revolution we are witnessing here, one made possible by communications technology, but made to happen because of marketing considerations.

The skilfut way in which American football has been sold to Europe is a good example of how all sports will develop. The aim of course is not really to spread the sport for its own sake, but to increase the number of people interested in the major money-making events. The economics of the Superbowl are already astronomical. With seats at US $125, gate receipts alone were a staggering $10,000,000.

So it came as a terrible shock, but not really as a surprise, to learn that some people are now suggesting that soccer change from being a game of two 45-minute halves, to one of four 25-minute quarters. The idea is unashamedly to capture more advertising revenue, without giving any thought for the integrity of a sport which relies for its essence on the flowing nature of the action. Moreover, as sports expand into world markets, and as our choice of sports as consumers also grows, so we will demand to see them played at a higher and higher level.

Globalization of sporting culture means that ______.

A.more people are taking up sports

B.traditional sports are getting popular

C.many local sports are becoming international

D.foreigners are more interested in local sports

"Mummy ! Mummy ! I saw some really big tadpoles (蝌蚪) in the pond (池塘). You've promised

"Mummy ! Mummy ! I saw some really big tadpoles (蝌蚪) in the pond (池塘). You've promised to catch some for us. "Phillip says, following me towards the kitchen. "Some of them have already got legs!" "Yes! We can catch them and watch them turn into frogs!" Geoffrey says suddenly. "Can we go? Right now?"The telephone has been ringing. I try to get the receiver, but it is too late. It has been cut off.

"Give me a minute to catch my breath. 'I beg. "Put the groceries away. Get some jars out. I'll go change."

We go to the wide pond which lies smooth and still, its surface dotted with pink (粉红色 ) and white lilies (睡莲). Phillip and Geoffrey, laughing and shouting, run to the water's edge. I feel the peace of the place broken by the children. I hope there are no tadpoles so we can leave quickly. There's dinner to cook.

It is quite some time before we have taken the first tadpole to the bank. "The children are wild with joy. Back in the pond we go, and we try hard to catch five more fat ones. We all agree that's enough. The sun has gone down. A frog goes to the opposite shore. It's well past dinner time, bath time and bedtime when we really leave. But none of us thinks of those things. Phillip and Geoffrey are in high spirits, and I am the same because I have done what I should.

Phillip and Geoffrey's voices must be ______.

A.sharp, nervous, tiresome

B.anxious, angry, inspiring

C.soft, sweet, pleasing

D.eager, excited, demanding

Every country tends to accept its own way of life as being the normal one and to praise or
criticize others as they are similar to or different from it. And unfortunately, our picture of the people and the way of life of other countries is often a distorted(曲折) one.

Here is a great argument in favor of foreign travel and learning foreign languages. It is only by traveling in, or living in a country and getting to know its inhabitants and their language that one can find out what a country and its people are really like. And how different the knowledge one gains this way frequently turns out to be from the second-hand information gathered from other sources! How often we find that the foreigners whom we thought to be such different people from ourselves are not very different after all!

Differences between peoples do, of course, exist and, one hopes, will always continue to do so. The world will be a dull place indeed when all the different nationalities behave exactly alike, and some people might say that we are rapidly approaching this state of affairs. With the much greater rapidity and ease of travel, there might seem to be some truth in this at least as far as Europe is concerned. However this may be, at least the greater ease of travel today has revealed to more people than ever before that the Englishman or Frenchman or German is not some different kind of animal from themselves.

Every country criticizes ways of life in other countries because they are______.

A.distorted

B.normal

C.similar to each other

D.different from its own
