We have no idea as to when men began to use salt, but we do know that it has been used m m

any different ways throughout the history.

For example, it is recorded in many history books that people who lived over 3000 years ago ate salted fish. Thousands of years ago in Egypt, salt was used to preserve the dead.

In some periods of history, a person who stole salt was thought to have broken the law. Take the eighteenth century for example, if a person was caught stealing salt, he would be thrown into prison. History also records that only in England about ten thousand people were put into prison during that century for stealing salt! About 450 years ago, in the year 1553, if a man took more than his share of salt, he would be thought to have broken the law and would be seriously punished. The offender's ear was cut off.

Salt was an important item on the dinner table of a king. It was always put in front of the king when he sat down to eat. Important guests at the king's table were seated near the salt. Less important guests were given seats farther away from it.

Thousands of years ago in Egypt salt was used ______.

A．to punish people who had broken the law

B．to keep dead bodies from decay

C．to keep fish alive

D．to make chemicals

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

People all have problems. If we don't deal with these problems, we can easily become

unhappy. Worrying about our problems can affect how we do at school. It can also influence the way we behave with our families. So how do we deal with our problems？ There are many ways and here is one of them

Most of us have probably been angry with our friends, parents or teachers. Perhaps they said something you didn't like, or you felt they were unfair. Sometimes people can stay angry for years about a small problem. Time goes by, and good friendship may be lost.

When we are angry, however, we are usually the ones affected. Perhaps we have seen young children playing together. Sometimes they have disagreements, and decide not to talk to each other. However, this usually does not last for long. This is an important lesson for us to learn.

Peter: Molly, look at this. The newspaper says we should sort trash.

Molly: That would be great! I always hate it when people mixing all the trash together.

Peter: () Many communities have already done that.

Molly: Yeah. The benefits of sorting out trash are obvious.

Peter: For instance？

Molly: If trash is sorted, it can be transferred to factories instead of the disposal plant.

Peter: That makes sense. ()Molly: With trash separated, pollution caused by incineration can be avoided.

Peter: It is high time for us to sort out the trash. Trash is trash only when everything is mixed together. () they can be useful again.

Molly: () Things like paper, glass, and plastics can all be recycled. They can be reused.

Peter: Sorting is good. () If people have no idea how to sort their trash, they will still put all waste in the same bag.

Molly: You are right. People should be informed about how to do that in the first place. Moreover, sorting trash should be made easy for us. Otherwise, few people would bother to do it.

Peter: I hope everything goes smoothly!

Molly: I believe it will.

A. I couldn't agree more.

B. What else？

C. Once we separate and recycle them.

Text 3Vinton Cerf, known as the father of the Internet, said on Wednesday that the Web was

outgrowing the planet Earth and the time had come to take the information superhighway to outer space.

“The Internet is growing quickly, and we still have a lot of work to do to cover the planet.” Cerf told the first day of the annual conference of Internet Society in Geneva where more than 1500 cyberspace fans have gathered to seek answers to questions about the tangled web of the Internet.

Cerf believed that it would soon be possible to send real-time science data on the Internet from a space mission orbiting another planet such as Mars. “There is now an effort under way to design and build an interplanetary Internet. The space research community is coming closer and closer and merging. We think that we will see interplanetary Internet networks that look very much like the ones we use today. We will need interplanetary gateways and there will be protocols to transmit data between these gateways, ” Cerf said.

Francois Fluckiger, a scientist attending the conference from the European Particle Physics Laboratory near Geneva, was not entirely convinced, saying: “We need dreams like this. But I don’t know any Martian whom I’d like to communicate with through the Internet.”

Cerf has been working with NASA’s Pasadena Jet Propulsion Laboratory—the people behind the recent Mars expedition—to design what he calls an “interplanetary Internet protocol.” He believes that astronauts will want to use the Internet, although special problems remain with interference and delay.

“This is quite real. The effort is becoming extraordinarily concrete over the next few months because the next Mars mission is in planning stages now,” Cerf told the conference.

“If we use domain names like Earth or Mars...jet propulsion laboratory people would be coming together with people from the Internet community.” He added.

“The idea is to take the interplanetary Internet design and make it a part of the infrastructure of the Mars mission.”

He later told a news conference that designing this system now would prepare mankind for future technological advances.

“The whole idea is to create an architecture so the design works anywhere. I don’t know where we’re going to have to put it but my guess is that we’ll be going out there some time,” Cerf said.

“If you think 100 years from now, it is entirely possible that what will be purely research 50 years from now will become commercial 100 years from now. The Internet was the same—it started as pure research but now it is commercialized.”

第31题：According to Cerf, the purpose to design interplanetary internet is to _____.

［A］ send real-time science data

［B］ communicate with astronauts

［C］ lay foundation for future technological advances

［D］ commercialize the technology

Is it possible that the ideas we have today about ownership and property rights have been

so universal in the human mind that it is truly as if they had sprung from the mind of God？ By no means. The idea of owning and property emerged in the mists of unrecorded history. The ancient Jews, for one, had a very different outlook on property and ownership, viewing it as something much more temporary and' tentative than we do.

The ideas we have in America about the private ownership of productive property as a natural and universal right of mankind, perhaps of divine origin, are by no means universal and must be viewed as an invention of man rather than an order of God. Of course, we are completely trained to accept the idea of ownership of the earth and its products, raw and transformed. It seems not at all strange; in fact, it is quite difficult to imagine a society without such arrangements. If someone, some individuals, didn't own that plot of land, that house, that factory, that machine, that tower of wheat, how would we function？ What would the rules be？ Whom would we buy from and how would we sell？

It is important to acknowledge a significant difference between achieving ownership simply by taking or claiming property and owning what we tend to call the "fruit of labor." If I, alone or together with my family, work on the land and raise crops, or if I make something useful out of natural material, it seems reasonable and fair to claim that the crops or the objects belong to me or my family, are my property, at least in the sense that I have first claim on them. Hardly anyone would dispute that. In fact, some of the early radical workingmen's movements made (an ownership) claim on those very grounds. As industrial organization became more complex, however, such issues became vastly more intricate. It must be clear that in modem society the social heritage of knowledge and technology and the social organization of manufacture and exchange account for far more of the productivity of industry and the value of what is produced than can be accounted for by the labor of any number of individuals. Hardly any person can now point and say, "That--that right there--is the fruit of my labor." We can say, as a society, as a nation--as a world, really--that what is produced is the fruit of our labor, the product of the whole society as a collectivity.

We have to recognize that the right of private individual ownership of property is man-made and constantly dependent on the extent to which those without property believe that the owner can make his claim, dependent on the extent to which those without stick.

According to the passage, the concept of ownership probably ______.

A．resulted from the concept of property right

B．stemmed from the uncovered prehistoric ages

C．arose from the generous blessing of the Creator

D．originated from the undetected Middle Ages

It seems like Americans use credit cards for everything. It's a lot easier to spend money

that you don't see, isn't it？ Many Americans spend money that isn't even there and get deeper and deeper in debt. Why do so many people spend more than they have？ "Buy now, pay later" has become an American way of life. Recently, American households spent nearly 11 billion dollars more than they earned, creating a negative saving rate.

There are two ideas—one, living within your means, and the idea that living on debt is a great equalizer(平衡装置). They both have validity because it is important that someone live within their means over their lifetime. When people are young and they are earning money, but they have very little savings, they almost have to borrow in order to own a house or own a car. But as they grow older, they should develop the habit of saving, so that by the time they reach the end of their earning life, they have savings to live on in retirement, and live within their means.

"Buy now, pay later" worked very well for us in the 1990s, but one suspects it won't work forever. The only thing that concerns me is that Americans are so contented, so optimistic, so unconcerned about any bumps in the road that many American households, not all of them, but many American households are very heavily extended in personal credit, a lot of credit card debt. People are paying very high prices for houses and borrowing heavily against those prices; and if we do run into a bump in the road, a recession, there are going to be a lot of households, not all of them, but many households that Ml be severely squeezed. That means we're more vulnerable to serious financial distress than Japan is. Japan has been in financial distress for ten years, but one reason it's been able to weather that is that the households had been very conservative, had a lot of savings, were very liquid, and were able to weather difficult times. And many American households would now be less able to do that because they are so heavily in debt.

We know from the passage that credit cards

A．make Americans get deeper and deeper in debt

B．are likely to be abandoned by more Americans

C．will soon become a symbol of American life

D．will help solve potential financial problems

Like most people, I was brought up to look upon life as a process of getting. It was not u

ntil in my late thirties that I made this important discovery: giving away makes life so much more exciting. You need not worry if you lack money. This is how I experimented with giving away. If an idea for improving the window display of a neighborhood store flashes to me, I step in and make the suggestion to the storekeeper. One discovery I made about giving away is that it is almost impossible to give away anything in this world without getting something back, though the return often comes in an unexpected form. One Sunday morning the local post office delivered an important special delivery letter to my home, though it was addressed to me at my office. I wrote the postmaster a note of appreciation. More than a year later I needed a post office box for a new business I was starting. I was told at the window that there were no boxes left, and that my name would have to go on a long waiting list. As I was about to leave, the postmaster appeared in the doorway. He had overheard our conversation. " Wasn't it you that wrote us that letter a year ago about delivering a special delivery to your home？ " I said yes. "Well, you certainly are going to have a box in this post office if we have to make one for you. You don't know what a letter like that means to us. We usually get nothing but complaints.

From the passage, we understand that______.

A．the author did not understand the importance of giving until he was in late thirties

B．the author was like most people who were mostly receivers rather than givers

C．the author received the same education as most people during his childhood

D．the author liked most people as they looked upon life as a process of getting

A man who knows a bit about carpentry （木工术) will make his table more quickly than the m

A man who knows a bit about carpentry (木工术) will make his table more quickly than the man who does not. If the instructions are not very clear, or the shape of a piece is puzzling his experience helps him to conclude that it must fit there, or that its function must be that. In the same way, the reader's sense and experience helps him to predict what the writer is likely to ,say next; that he must be going to say this rather than that. A reader who can think along with the writer in this way will find the text.

This skill is so useful that you may wish to make your students aware of it so that they can use it to tackle difficult texts. It does seem to be the case that as we read we make hypotheses (假设) about what the writer intends to say; these are immediately modified by what he actually does say, and are replaced by new hypotheses about what will follow. We have all had the experience of believing we were understanding a text until suddenly brought to a halt by some word or phrase that would not fit into the pattern and forced us to reread and readjust our thoughts. Such occurrences lend support to the notion of reading as a constant making and remaking of hypotheses.

If you are interested in finding out how far this idea accords with (符合) practice, you may like to try out the text and questions. To do so, take a piece of card and use it to mask the text. Move it down the page, revealing only one

t a time. Answer the question before you go on to look at the next section. Check your prediction against what the text actually says, and use the new knowledge to improve your next prediction. You will need to look back to earlier parts of the text if you are to make accurate prediction, for you must keep in mind the general organization of the argument as well as the detail within each sentence. If you have tried this out, you have probably been interested to find how much you can predict, though naturally we should not expect to be right every time -- otherwise there would be no need for us to read.

Conscious use of this technique can be helpful when we are faced with a part of the text that we find difficult: if we can see the overall pattern of the text, and the way the argument is organized, we can make a reasoned guess at the next step. Having an idea of what something might mean can be a great help in interpreting it.

The author uses the examples of carpentry and reading to show______.

A．the importance of making prediction

B．the similarity in using one's senses

C．the necessity of making use of one's knowledge

D．the most effective method in doing anything
