在水稻种植领域，中国科学家袁隆平是一位杰出人士。
他认为解决人们吃饭问题的关键在于拥有更多的稻米，并且能更快地生产出来。
袁隆平的发现结果使中国的水稻产量在20世纪90年代增长了47.5%。
通过使不同品种的水稻杂交，他能够生产出一种比原植物任何之一的产量都高的新植物。
五万平方公里的稻田都转向种植蔬菜和其他经济作物了。
为表彰他的工作，David Ho被命名为时代杂志1996年年度人物。(page 20)

The right pair of exercise shoes can do a lot to prevent discomfort and injuries, personal trainers say．Here are some shopping tips:
1 Depending on your workout, shoes designed for walking, running, tennis, cross-training or another specialty will provide the best support for your feet．
Shop when you normally exercise．Feet actually get bigger throughout the day, sometimes swelling up as much as a half-size by nighttime． 2
Try them on．Never grab a pair of exercise shoes based only on the size of footwear you normally buy．Bring the type of socks you’d wear to work out and go for a walk through the store．
3 You should be able to spread your toes out comfortably．Make sure there’s about a half-inch of space between them and the front of the shoe．The back should fit snugly (warmly and comfortably) against your heel and not move up and down．If your feet are different sizes, buy based on the larger one．
Talk to an expert．Shoe salesmen and personal trainers can study your stride (步伐) and the shape of your feet． 4
5 Many trainers recommend switching footwear every three to five months, if possible, to maintain（保持）proper cushioning and support．
One tip: if you have to tie your shoes very tightly to feel a good amount of support, they may be ready to go．
A．Think about how much you can afford to buy the workout shoes．
B．Consider your type of exercise．
C．Focus on fit．
D．So don’t shop first thing in the morning if you often work out in the evening．
E．Pay more attention to new style shoes．
F．Replace worn shoes regularly．
G．Usually they can recommend the best shoes to guard against injuries．

Dear Editor,
I’m a middle school student naming Lily. I’m writing to tell you something I don’t think it good. Recently I’ve noticed many of my classmates often went to the Internet bar near our school. The other day I went there, too. I was very surprising to see many students playing games, seeing films and chatting. Some were even talking about love affairs on-line. In my opinion, an Internet bar should be a place which we can find much useful information. As is known to all that the Internet is a window to an outside world rather than a place for games. The Internet is good if we make good use it. Otherwise, it will do us great harm. So the local government should take measure to make sure that the students use Internet bars positively.
阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

Married by arrangement at 13, Gandhi went to London to study law when he was 13. From 1893 to 1914 he worked for an Indian firm in South Africa. Gandhi was against the racial unfair treatment there. He accepted leadership of protest（抗议） campaigns and gradually developed his techniques of nonviolent resistance（反抗）known as Satyagraha .
Returning to India in January 1915, Gandhi soon became involved in labor organizing. The Jallianwala Bagh mass murder of Amritsar (1919), in which troops fired on and killed hundreds of nationalist demonstrators（示威者）, turned him to direct political protest. Within a year he was the important figure in the Indian National Congress. He launched on a policy of noncooperation with the British in 1920-22. Although total noncooperation was given up, Gandhi continued civil disobedience, organizing protest marches against unpopular British measures, such as the salt tax (1930), and refusing British goods.
Gandhi was repeatedly sent to prison by the British and used hunger strikes as part of his civil disobedience. His final imprisonment came in 1942-44, after he had demanded total withdrawal of the British (the "Quit India" movement) during World War II.
Gandhi also fought to improve the life of the lowest classes of society, the ‘Untouchables’, whom he called harijans ("children of God"). He believed in manual labor and simple living; he spun thread and made cloth for his own clothes and insisted that his followers do so, too. He disagreed with those who wanted India to industrialize.
Gandhi was also tireless in trying to form closer ties between the Hindu majority and the numerous minorities of India, particularly the Muslims. He was killed in Delhi on January 30, 1948, by a Hindu murderer who mistakenly thought Gandhi's policy was evil .
1. We can infer from the passage that .
A. Gandhi had many children B. Gandhi had a wonderful family life
C. Gandhi got married because his family wanted him to. D. Gandhi was a good father
2. The underlined word “withdrawal” in Paragraph 4 most probably means .
A. removing B. staying C. making peace D. fighting
3. According to the passage, we know that .
A. Gandhi would like to build modern cities B. Gandhi would like to give parties
C. Gandhi would like to build many factories D. Gandhi would like to live in a village
4. Which of the following is true?
A. The murderer hated the Muslims very much B. The writer thought well of the murderer.
C. Gandhi didn’t care about the poor D. British measures were welcome in India
B
A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.
A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.
P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.
Mr. Engelma n says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.
The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.
The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.
The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.
5. are expected to have severe water problems by the year 2025
A. No countries B. 18 countries C. 28 countries D. 46 countries
6. All the following are true except .
A. Lack of water may cause conflict between countries
B. Egypt now has enough fresh water
C. There are solutions to the water problem
D. New industries need a lot of water
7. It can be inferred that .
A. Lack of water may also result from international conflict
B. There is connection between providing clean water and slowing population growth
C. The ability of developing has nothing to do with lack of water.
D. It is not known whether diseases have something to do with lack of water
8. The best title of the passage would be
A. World Conflict B. Diseases and Water C. World Water Shortage D. Population and Water
