However,it has been found that even people insensitive to a certain smell at first can suddenly become sensitive to it when( )to it often enough.

A.subjected
B.left
C.drawn
D.exposed
参考答案和解析
答案:D
解析:
本题所在的句子是一个由when引导的条件句,由主句的主语可以推断,该从句省略了主语和谓语即people are。同时,从句中的it指代的是上文的a certain smell,由此可推断本句意思是:如果人能经常闻到这种气味也能突然对它变得敏感。而四个选项中,只有D.expose一词能与to搭配表示“使某人接触到……”,在这里引申为闻到气味。

第1题:

The Building of the Pyramids

The oldest stone buildings in the world are the pyramids.【46】 There are over eighty of them scattered along the banks of the Nile, some of which are different in shape from the true pyramids. The most famous of these are the "Step" pyramid and the "Bent" pyramid.

Some of the pyramids still look much the same as they must have done when they were built thousands of years ago. Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often, for stone to use in modem buildings.【47】. These are good reasons why they can still be seen today, but perhaps the most important is that they were planned to last for ever. 【48】. However, there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves.【49】. Nevertheless, by examining the actual pyramids and various tools which have been found, archaeologists have formed a fairly cleat picture of them.

One thing is certain: there must have been months of careful planning before they could begin to build.【50】 You may think this would have been easy with miles and miles of empty desert around, but a pyramid could not be built just anywhere. Certain rules had to be followed, and certain problems had to be overcome.

A. The dry climate of Egypt has helped to preserve the pyramids, and their very shape have made them less likely to fall into ruin.

B. It is practically certain that plans were made for the building of the pyramid because the plans of other large works have fortunately been preserved.

C. The first thing they had to do was to choose a suitable place.

D. Consequently, we are only able to guess at the methods used.

E. Many people were killed while building the pyramids.

F. They have stood for nearly 5,000 years, and it seems likely that they will continue to stand for thousands of years yet.

Passage Two

When 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 out

of 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 perfectly

B. only when we can see well

C. even if we can see well

D. only when we realize how important our eyes are

Passage Two

Questions 26 to 30 are based on the following passage.

A few years ago it was fashionable to speak of a generation gap,a division between young people and their elders. Parents complained that children did not show them proper respect and obedience,while children complained that their parents did not understand them at all. What had gone wrong? Why had the generation gap suddenly appeared? Actually,the generation gap has been around for a long time. Many critics argue that it is built into the fabric of our society.

One important cause of the generation gap is the opportunity that young people have to choose their own life styles. In more traditional societies,when children grow up,they are expected to live in the same area as their parents,to marry people that their parents know and approve of,and often to continue the family occupation. In our society,young people often travel great distances for their educations,move out of the family home at an early age,marry-or live with-people whom their parents have never met,and choose occupations different from those of their parents.

In our upwardly mobile society,parents often expect their children to do better than they did:to find better jobs,to make more money,and to do all the things that they were unable to do. Often,however,the ambitions that parents have for their children are another cause of the division between them. Often,they discover that they have very little in common with each other.

Finally,the speed at which changes take place in our society is another cause of the gap between the generations. In a traditional culture,elderly people are valued for their wisdom,but in our society the knowledge of a lifetime may become obsolete overnight. The young and the old seem to live in two very different worlds,separated by different skills and abilities.

No doubt,the generation gap will continue to be a feature of American life for some time to come. Its causes are rooted in the freedoms and opportunities of our society,and in the rapid pace at which society changes.

The main idea of the first paragraph is that______.

A. the generation gap suddenly appeared

B. the generation gap is a feature of American life

C. how people can reduce the generation gap

D. many critics argue over the nature of the generation gap

Better Life for All

In today’s society, working people can seldom find time to relax themselves in their busy schedules. They often work overtime because of too much work waiting in queue, which ends up causing a lot of physical and mental problems. However, more people are now aware that relaxation and stress-relief are necessary for life. One’s health should never be sacrificed for a need to work hard. Indeed, finding time to relax makes people work more efficiently.

Many people plan trips to spend their free time travelling with their loved ones. This may have been a luxury in the past, but it has become more common in recent years. Travelling at home and abroad has now become convenient and affordable.

Going jogging and going to the gym have also become more popular, as they are rather convenient ways to exercise and stay fit. Exercising helps relax your body and has been shown, to relieve mental stress as well. This demand for recreation and leisure service has also stimulated the economy, as new businesses are created to meet these needs.

In sum, working hard is important, but having a good quality of life can actually facilitate your success at work. Knowing when and how to relax should be a part of well -balanced lifestyle. Take a walk outdoors, visit the gym, or go jogging. You will find that your time was not wasted, even if it was not spent working in your office.

Sometimes the processes in which people are engaged are dependent upon other processes being completed first, possibly by other people. For example, on an automobile(71), it is necessary for the body to be constructed before the doors can be added on. Attempting to add the doors first would be pointless, because there would be nowhere to attach them. Thus, if there is no body ready to have doors added, the process for adding doors has to be(72)until the process for creating the next body is complete. This is known as(73)

Obviously, there are many cases where people have to wait for other people to do something. However, if everyone in such a situation is waiting for someone else to do something first, then no one will ever be able to do anything. When discussing processes, this situation is known as(74), because all of the involved processes are effectively dead because of locks they have on resources. Usually someone in such a situation will eventually notice and abort the process, allowing normal flow to(75), and often warning signs can even be spotted ahead of time to avoid 'it in the first place.
