Farmers use different kinds of soil conservation methods to protect their land from damage by farming and the forces of nature . One important form of soil conservation is the use of windbreaks . Windbreaks are barriers formed by trees and other plants with many leaves . Farmers plant them in lines around their fields .
Windbreaks stop the wind from blowing soil away . They also keep the wind from destroying or damaging crops . They are very important for growing grains , such as wheat . There have been studies done on windbreaks in parts of West Africa , for example . These found that grain harvests can be twenty percent higher in fields protected by windbreaks compared to fields without such protection .
However , windbreaks seem to work best when they allow a little wind to pass through . If the wall of trees and plants stops wind completely , then violent air motions will take place close to the ground . These motions will lift soil into the air where it will be blown away .
For this reason , a windbreaks is best if it has only sixty to eighty percent of the trees and plants needed to make a solid line . An easy role to remember is that windbreaks can protect areas up to ten times the height of the tallest trees in the windbreaks .
These should be at least two lines in each windbreak . One line should be large trees . The second line , right next to it , can be shorter trees and other plants with leaves . Locally grown trees and plants are best for windbreaks .

　　A picture, a calendar or even a balloon may be the best way for millions of people living in China’s vast country areas to learn about AIDS, one of the biggest threats to public health in the world today．

　　China has decided to use user-friendly methods including exhibitions, VCDs and TV programmes to spread knowledge of the disease across the nation to try to keep it in check．

　　Educating people nationwide about AIDS is the top priority(優(yōu)先權(quán))to prevent the disease from getting out of hand．The farmers will be given knowledge in the easiest way that they can understand．?

　　A recent survey from the commission(調(diào)查團(tuán))of more than 7000 people in China showed that nearly 20 percent of them had never heard of AIDS before．Just over 71 percent said they knew AIDS was highly infectious(傳染的), but most of them had no clear idea of how the disease could be spread．Just over 62 percent said they knew they could do things in advance to prevent them catching AIDS but they didn’t know what these measures were．

　　The month-long survey, carried out last December, talked to people in seven countries and cities across China including both developed coastal areas and the less-developed inland areas．The interviewees ranged from 15 to 49 years old, and country residents(居民)were about 63％ of the total surveyed．?

　　Chinese people, especially those in the country, have very little knowledge about what AIDS is all about, not to mention prevention and treatment．By the end of last year, there were 22 517 known HIV/AIDS cases in China．However, more than 6 000 000 people in China have been infected．

　　Since 1985, China has discovered 880 patients with AIDS－466 of them have died．Sharing needles, prostitution(賣(mài)淫)and contaminated blood transfusions(輸血傳播)are major ways for HIV to spread．A lack of education has been the biggest difficulty against nationwide efforts to prevent AIDS, especially in the countryside．

(1)

We human beings haven’t been good friends to animals. For thousands of years, we have been polluting the environment, making it hard for animals to live on the planet. We have been killing animals for their fur, feathers or meat, or simply because they are dangerous. As a result, many kinds of animals have disappeared forever. Hundreds more are on the endangered list today.
Should we care about animals? Of course we should. If animals of a certain kind all disappear, they will never come back again. Animals are more than just resources of things we need. Every kind of animal has its place in the balance of nature. Destroying any kind of animal can lead to many problems. For example, when farmers killed large numbers of hawks, the corn and grain that the farmers stored were destroyed by rats and mice. Why?  Because hawks eat rats and mice. With less and less hawks to keep down their numbers, rats and mice multiplied quickly. And if people kill too many birds, more and more insects will eat the crops.
Luckily, we’ve realized that we shouldn’t kill animals any more. And people are working hard to save those animals that would disappear soon. The government also passed laws to protect the endangered animals. In fact, quite a few countries have passed such laws. These laws forbid the killing of any kind of animal on the endangered list. We should try our best to protect and save the endangered animals.
【小題1】The text calls on us to__________.

A．keep animals at homeB．protect the environment
C．protect the endangered animalsD．know more about the balance of nature.
【小題2】Why do people kill animals?
A．Animals cause many serious problems.
B．They kill animals for something they need.
C．Animals destroy their natural resources.
D．They kill animals to protect the environment
【小題3】The example that farmers killed hawks shows that__________.
A．there were too many rats and mice
B．hawks are the most important in the nature
C．a(chǎn)nimals are good food resources
D．every kind of animal is important in nature

B

Save the Animals

Animals are natural resources that people have wasted all through our history.

Animals have been killed for their fur and feathers(羽毛), for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.

Why should people care? Because we need animals. And because once they are gone, there will never be any more.

Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.

For example, when farmers killed large numbers of hawks (鷹), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied (繁殖) quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.

Quite a few countries have passed laws. These laws prohibit the killing of any animal or plant on the danger list.

A . they give us a source of food             B. they are beautiful and lovely

A. About 170 kinds of animals have disappeared forever.

B. Thousands of kinds of animals are gone forever.

63. Why do people kill animals?

A. They kill animals for something they need.

B. They kill animals to raise some money.

C. Animals destroy their natural resources.

D. Animals create many problems.

64. What does the underlined word “prohibit” mean in the last paragraph?

A. prevent           B. stop              C. forbid            D. allow

65. What can we infer(推斷) from the fact that quite a few countries have passed laws protecting animals in danger?
