Scientists are trying to make the deserts into good land again. They want to bring water t

o the deserts, so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming desert all the time. Scientists may not be able to change the desert. Scientists think that people make deserts. People are doing bad things to the earth.

Some places on the earth don't get very much rain. But they still don't become deserts. This is because some green plants are growing there. Small green plants and grass are very important to dry places. Plants don't let the hot sun make the earth even drier. Plants don't let the wind blow the dirt(土)away. When a little bit of rain falls, the plants hold the water. Without plants, the land can become a desert much more easily.

Deserts ______.

A．get very little rain

B．never have any plants or animals in them

C．can all be turned into good land before long

D．both A and C

During the 19th century, scientists found that when certain parts of the brain of a pe

rson were hurt, he would lose the power of doing certain things. And so people thought that each part of the brain does a different job. But modem research discovered that this is not so, for it is not easy to show exactly what each part of the brain does. In the past fifty years there has been a great increase in the amount of research done on the brain. Scientists have found out the way the brain works is not so simple as people in general may think. Chemists fell us that about 100 000 chemical changes take place in the brain every second. Some recent researches also suggest that we can remember everything that happens to us. We, may not be able to think of the things we have heard and seen, but it is kept there in the storehouse (宝库 ) of the human brain. Earlier scientists thought that is not true. As long as the brain is given plenty of exercise, it keeps its power. It has been proved that an old person who has always been active in the mind has a quicker mind than a young person who has only done physical work without using much of his brain.

2.Scientists today are still unable to show exactly()

A、what each part of the brain is doing

B、how many chemical changes take place in the brain each second

C、whether each part of the brain does the same job

D、which part of the brain is the most important

3.It has been found that one's brain usually works ()

A、faster when he is old

B、a little now and a little then

C、in a very simple way

D、more complicated than we thought

4.Which of the following is NOT true according to the text？()

A、Scientists are working hard at the researches on the brain.

B、As many as six million chemical changes take place in the brain every minute.

C、A young man doing physical labor is sure to have a much slower min

D、Even an old man may have a quick mind if his brain is given much exercise.

5.The more work we give to our brains()

A、the less result we will gain

B、the more work they are able to do

听力原文：Today I'd like to mention an interesting television program that will be shown on

听力原文： Today I'd like to mention an interesting television program that will be shown on October 10th. It's about the brain. It's a new public television show produced in New York City. The program will investigate how the brain functioned and new functions. Some interesting topics that will be discussed are dreaming, memory, and depression. These topics will be illustrated by using computer imitations of the brain to make explanation easy to follow. The show is not for children. But don't worry. It's not intended for scientists either. I think the program will be very helpful with the work we're doing in class on the brain. I hope you'll watch it. Remember it's on October 10th.

(33)

A．A computer specialist.

B．A scientist.

C．A television announcer.

D．A teacher.

In the 1980s to mid-1990s, the United Kingdom consistently 【C1】______ many more populous countries in 【C2】______ number of papers produced and citations received per paper in science, medicine, and engineering. During the 20th century, the United Kingdom 【C3】______ more major international scientific prizes per capita than any other nation--about 10% of all such 【C4】______ .

Many explanations have been 【C5】______ for this success. Some British attribute it 【C6】______ a superiority of intellect and 【C7】______ . Yet British scientists are a more 【C8】______ group than American scientists, 【C9】______ selective pressure throughout secondary and undergraduate education.

I must 【C11】______ that at first I was frustrated by the slower 【C12】______ of research in the United Kingdom in 【C13】______ with that in the United States. Having recently completed my doctoral research in the 【C14】______ envi-ronment 【C15】______ of many U.

听力原文：Scientists in many developing nations are studying a way to protect and control t

听力原文： Scientists in many developing nations are studying a way to protect and control the use of forests, fishing water, grasslands and other resources. They call the system "common property". It means that people join together to abate and protect the resources. Scientists say that increased population is damaging the world resources. Too many trees are cut; grasslands and croplands are destroyed. Too many fish are taken from the fishing area. There are two traditional ways to deal with this situation. One is public: the government agency decides who may use the resources and when; or the property can be private: the owner decides how to protect the resources. Experts say these two methods often are not effective, however. They believe there is a third possibility that is neither completely governmental nor completely private. It is communal or joint control of the resources.

Scientists know that this idea of common property is not new. The system has been believed successful for a long time by groups in many countries. In South Asia, some villagers have governing systems to protect everyone's right to irrigation water. In part of Central Africa, there are traditional rules that banned the killing of some wild animals. Farmers in Syria have a system to share grasslands and fisherman in Turkey have a system to make sure no one takes too many fish. Scientists say such systems usually were developed by small groups to deal with limited problems. Rules are simple and the enforcement is based on traditional value and ways of doing things. Scientists believe such systems also would be effective in other situations. They are studying how it might produce more cooking rules for people in Indian villages. The scientific group in Costa Rice is studying common property to control land area. And a government group in Zimbabwe is studying the system to protect wild animals. Scientists do not say the common property system will solve all resource needs in developing nations, buy they believe it provides one important way to deal with the problem.

(33)

A．Property owned by a group of people.

B．Privately-owned property.

C．Government-owned property.

D．People's joint effort to share and protect natural resources.
