Water is necessary for life and good health. We often forget this fact when we think about
the other building blocks of life, such as vitamins, minerals and proteins. We can live for many days without eating. However, only two or three days without water usually leads to death.

The human body may look solid, but most of it is water. New-born babies are as much as eighty-five percent water. Women are about sixty five percent water, and men about seventy-five percent. Women usually have less water than men because women, in general, have more fat cells. Fat cells hold less water than other kinds of cells.

Water is necessary for cooling the body on hot days, and when we are working hard or exercising. Water carries body heat to the surface of the skin when the heat is lost through perspiration.

Researchers note that fat cells block body heat from escaping quickly. Fat cells under the skin act like warm clothing to keep body heat inside. This is why over-weight people have a more difficult time staying cool than thin people.

Researchers also note that cold liquids cool us faster than warm liquids. This is because cold liquids take up more heat inside the body and carry it away faster. They say, however, that cold sweet drinks do not work well. The sugar slows the liquid from getting into the bloodstream.

The body loses water every day through perspiration and urine. If we lose too much, we will become sick. To replace what is lost, health experts say grown persons should drink about two liters of liquids each day, and more in hot weather. They say we also can get some of the water we need in the foods we eat. Most fruits and vegetables have more than eighty percent water. Even bread has about thirty-three percent water.

From the passage we learn that among the following four groups of people _______.

A.fat women are over eighty percent water

B.thin men are never eighty percent water

C.new-born infants are over eighty percent water

D.elderly adults are over eighty percent water

We can make mistakes at any age.Some mistakes we make are about money.But most mistake
s are about people."Did Jerry really care when I broke up with Helen?" "When I got that great job, did Jerry 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, we miss the feeling behind the words.Suppose someone tells you, "you're a lucky dog".Is he really on your side? If he says, "You're a lucky guy" or "You're a lucky gal", 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" bit puts you down a little.What he may be saying is that he doesn't think you deserve your luck.

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 square with the tone of voice? His posture (体态)? 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.

1.From the questions in the first paragraph we can learn that tile speaker ().

A.feels happy, thinking of how nice his friends were to him

B.feels he may not have "read" his friends' true feelings correctly

D.is sorry that his friends let him down

D.the word "dog" shouldn't be used to apply to people

3.This passage tries to tell you how to ().

The Great Wall is one of the wonders of the world that created by human beings! If you
come to China without climbing the Great Wall, it's just like going Paris without visiting the Eiffel Tower(埃菲尔铁塔); or going to Egypt without visiting the Pyramids(金字塔).Men often say, “He who does not reach the Great Wall is not a true man.”In fact, it began as independent walls for different states when it was first built, and did not become the “Great Wall” until the Qin Dynasty.However, the wall we see today, starting from Shanhaiguan Pass in the east to Jiayunguan Pass in the west, was mostly built during the Ming Dynasty.

There have been three periods in the history of post-war broadcast interviewing. The first
, "the age of respect", when it was an honour to have you, the interviewee, on the programme, lasted until the middle 50s. The second, "the age of supremacy", when politicians in particular looked upon the interviewers as rivals who made them feel uncomfortable by their knowledge and rigour of questioning, came to an end at the beginning of this decade. Now we are in "the age of evasion", when most prominent interviewees have acquired the art of seeming to answer a question whilst bypassing its essential thrust.

Why should this be? From the complexity of causes responsible for the present commonplace interview form, a few are worth singling out, such as the revolt against rationality and the worship of feeling in its place. To the young of the 60s, the painstaking search for understanding of a given political problem may have appeared less fruitful and satisfying than the free expression of emotion which the same problem generated. Sooner or later, broadcasting was bound to reflect this.

This bias against understanding has continued. To this we must add the professional causes that have played their part. The convention of the broadcast interview had undergone little change or radical development since its rise in the 50s. When a broadcasting form. ceases to develop, its practitioners tend to take it for granted and are likely to say "how" rather than ask "why".

Furthermore, these partly psychological, partly professional tendencies were greatly accelerated by the huge expansion of news and current affairs output over the last 15 years. When you had many, additional hours of current affairs broadcasting, interviewing turned out to be a far cheaper convention than straight reporting, which is costly in terms of permanent reporters and time preparation. The temptation to combine an expanded news and current affairs service with a relatively small additional financial expense by making the interview happen everywhere proved overwhelming.

To be fair, there are compensating virtues in interviewing, such as immediacy and authority, yet in all honesty I must say that the spread of the interviewing arrangement has led to a corresponding diminution of quality broadcasting.

According to the author, in the past politicians thought that television interviewers ______.

A.knew more about politics than they did

B.should be honoured to meet them

C.really were eager to be politicians too

D.gave them a difficult time in interviews

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

Sometimes, people simply do not realize they are being ill mannered. Take Ted, for example
. He prides himself on speaking his mind, and has something to say on everything. But his frankness is often extremely embarrassing.

He is incapable of saying, " I thought that last advertising campaign had a lot of good ideas in it, but perhaps next time we could give the copy more vitality(活力). " Instead, he would say, " That campaign was a disaster. A child of three could have done better !"

The fact that he is often right does not help. Other employees dislike his manner even more, but he is too insensitive to notice.

Another character among the list of ill-mannered employees is Sally, who seems to regard just being at work as a severe punishment. Everything is done unwillingly. Asking her to do a task beyond her basic job description is often not worth the trouble. It will be done, but only half-heartedly.

Fergus is just the opposite. He shows an over-familiarity to his boss. When an important visitor is shown into the manager's office, Fergus cannot take the hint and leave. Instead he will attempt to take part in the conversation, declaring, "You can talk in front of me. Henry and I don't have many secrets, do we?" Over the years Fergus has fallen behind his former equal. But he seeks to maintain the same close relationship that he imagines existed in their younger days.

Which of the following words describes Ted best?

A.Cold.

B.Tactless.

C.Stupid.

D.Warm-hearted.

第10题
The study of philosophies should make our own ideas flexible. We are all of us apt to take
certain general ideas for granted, and call them common sense. We should learn that other people have held quite different ideas, and that our own have started as very original guesses of philosophers.

A scientist is apt to think that all the problems of philosophy will ultimately be solved by science. I think this is true for a great many of the questions on which philosophers still argue. For example, Plato thought that when we saw something, one ray of light came to it from the sun, and another from our eyes and that seeing was something like feeling with a stick. We now know that the light comes from the sun, and is reflected into our eyes. We don't know in much detail how the changes in our eyes give rise to sensation. But there is every reason to think that as we learn more about the physiology of the brain, we shall do so, and that the great philosophical problems about knowledge are going to be pretty fully cleared up.

But if our descendants know the answers to these questions and others that perplex us today, there will still be one field of which they do not know, namely the future. However exact our science; we cannot know it as we know the past. Philosophy may be described as argument about things of which we are ignorant. And where science gives us a hope of knowledge it is often reasonable to suspend judgment. That is one reason why Marx and Engels quite rightly wrote to many philosophical problems that interested their contemporaries.

But we have got to prepare for the future, and we cannot do so rationally without some philosophy. Some people say we have only got to do the duties revealed in the past and laid down by religion, and god will look after the future. Others say that the world is a machine and the course of future events is certain, whatever efforts we may make. Marxists say that the future depends on ourselves, even though we are part of the historical process. This philosophical view certainly does inspire people to very great achievements. Whether it is true or not, it is powerful guide to action.

We need a philosophy, then, to help us to tackle the future. Agnosticism easily becomes an excuse for laziness and conservatism. Whether we adopt Marxism or any other philosophy, we cannot understand it without knowing something of how it developed. That is why knowledge of the history of philosophy is important to Marxists, even during the present critical days.

What is the main idea of this passage?

A.The argument whether philosophy will ultimately be solved by science or not.

B.The importance of learning philosophies, especially the history of philosophy.

C.The difference between philosophy and science.

D.A discuss about how to set a proper attitude towards future.
