　　Passage A

　　阅读理解

　　In some countries in which there is very little rain at any time, the farmers have to irrigate their fields. Irrigation is easy enough if there is a great river near the crops, and if there is plenty of water in it. Canals (沟渠) carry the river water to the fields when necessary. In some seasons there may be too much water in the river, and the water may flood all the land near it. At other times the river water may not be enough for all the farmers, and then it will be difficult to irrigate the fields.

　　To prevent these difficulties, a dam (水坝) may be built across the river. This will store water for dry seasons, and in wet seasons it will prevent the flooding of the land.① A great lake will, no doubt, be formed behind the dam, and this may mean that houses and fields will be covered with water. Most people will accept that and will be ready to move to other places. Then the country can have the right amount of water at all times; more crops will be grown, there will be more food for everyone, and there will be no more floods.

　　We cannot use sea water for irrigation; the salt will not allow the crops to grow. Fresh water is always needed, and it is very difficult and costly to make fresh water from sea water. This is done in a few countries, but the fresh water is for drinking. There is not enough at present for irrigation. Perhaps a scientist will one day invent a cheaper way of producing fresh water from the sea. If fresh water could be made cheaply, we could grow more food. ②

　　Passage B

　　阅读理解

　　Health officials are worried about a flu (流感). But this isnt the same kind of flu that might have kept you out of school last week. It's the bird flu, which has spread to 10 Asian countries.

　　The disease affects (侵袭) birds such as chickens and ducks, and can also spread to humans. So far, only people who have handled chickens have been infected (感染). Although there is no sign of the disease spreading from human to human, experts are not ruling out that possibility.

　　The disease first infected humans in Hong Kong in 1997, but appeared in Italy over 100 years ago. This year, at least 10 people have died from the disease, and health experts fear it could become worse. If the virus (病毒) continues to grow at a fast rate, it could become a bigger problem than SARS, which used to kill about 800 people last year.

　　To prevent the situation from becoming worse, infected chickens and ducks throughout Asia are being killed. China has already killed tens of thousands of birds. Scientists are also working as hard as they can to create a vaccine (疫苗) to protect people, but it will probably not be ready for at least another six months.

　　“We have a window of opportunity here to deal with this disease.①” said Dr Klaus Stohr of the World Health Organization. “With SARS we said we wanted to put things back in a box;② here we want to keep things in the box. It hasnt come out yet. We have a good chance of controlling this.”

　　根据文章内容，选择正确答案：

　　1. What is the bird flu?

　　A. A disease suffered by animals.

　　B. A disease suffered by birds.

　　C. A disease suffered by animals and humans.

　　D. A disease suffered by birds and humans.

　　2. Which of the following statements is TRUE to the fact?

　　A. The bird flu only appeared in Asia.

　　B. The bird flu is not able to spread between humans like SARS.

　　C. The bird flu first appeared in Hong Kong.

　　D. The bird flu could be more serious than SARS.

　　3. What can we learn from the last paragraph?

　　A. The bird flu has developed into a serious problem which is beyond people's control.

　　B. The bird flu has caused as bad an effect to humans as SARS.

　　C. Now people have developed ways to deal with the disease of the bird flu.

　　D. People are quite sure about bringing the bird flu into control.
