A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃．Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate．Without the forest cover，these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world．

In the past hundred years，humans have begun destroying rainforests in search of three major resources(资源)：land for crops，wood for paper and other products，land for raising farm animals．This action affects the environment as a whole．For example，a lot of carbon dioxide (二氧化碳)in the air comes from burning the rainforests．People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.

There are two main reasons for this．Firstly，when people cut down trees，generally they can only use the land for a year or two．Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world’s wood supply．

Rainforests are often called the world’s drug store．More than 25％ of the medicines we use today come from plants in rainforests．However，fewer than l％of rainforest plants have been examined for their medical value．It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests．

A．reflect more heat into the atmosphere

B．bring about high rainfall throughout the world

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

Interviewer-------- Why is English so important?

David------- Well, English is so important primarily because so many people speak it and use it, so it has now become the lingua franca in the world in a way that we’ve never seen before. We’ve never had a world language of this kind before. So people are learning it not just to be able tocommunicate with native speakers, but also with speakers of other language around world.

Interviewer-------And why has it become that dominant language?

David------I think the reason for that is actually very complicated, although in the twentieth century, we can just see that it’s the rise of the US military and consumer power. I mean the technology, all the big developments in technology largely came from the US. So all of these developments actually were produced within the English language, and people had to learn English in order to understand them, or to benefit from them. The Internet is only one example of that kind. Once a language has got into that position of dominance, it’s actually very different to shift it. So we could be seeing the emergence of other big languages in the world becoming more important than they have been, like Spanish, but it’s unlikely that they’re going to shift the English from its position of dominance.
