Task2If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory （记忆力） works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault (过错). But if he tells us that he has a poor memory, many of us think that his parents are to blame (受责备), and few of us know that it is just his own fault. Have you ever found that some people can't read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.6. The main reason for one is poor memory is that ________.A. his father or mother may have a poor memoryB. He does not use his name or legs for some timeC. his memory is not often usedD. he can’t read or write7.

Task3The Three Gorges Dam (三峡大坝), the longest dam in the world, is also the largest engineering project on the surface of the earth. It aims to make the mother of all floods, the Yangtze River, into a tame river and it will be the largest power source for much of eastern and central China. It will create a huge, deep-water lake, and make it possible for 10,000-ton-ocean-going ships to sail 1,500 miles inland from the Pacific to the city of Chongqing with its 30 million people, making it one of the world’s largest river ports.Construction has already started. The dam will be about 6,860 feet long and 611 feet high, at a spot called Sandouping near Yichang.After several decades of investigation, experts have drawn a conclusion that this grand project will do a great deal of good. The most important is flood control. By building a dam instead of new coal plants to meet its growing demand of electricity, China will give off much less poisonous gases into the air.The Three Gorges Dam could be considered, when it is finished in 2009, the eighth wonder of the world as to size alone.1.
