The Three Gorges Dam, the largest dam, is also the largest engineering project on the face of the earth. It aims to make the mother of all floods, the Yangtze River, into a tame river, and to generate power of 181,200 megawatts for Eastern and Central China. It will form 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, making it one of the world’s largest inland ports.
Construction has already started. The dam will be about 6,860 metres wide and 611 feet high, at a spot called Sandouping near Yichang.
It is obvious that such a grand project will do much good. It is the most important to control floods. By building hydropower plants, China will offer much in environmental protection.
However, some scientists don’t agree to the project. They say that Chongqing and dozens of other cities along the river will pollute the reservoir, which will destroy the ecological balance and also the sand from upstream will form sand-bed.
The Three Gorges Dam could be considered when it is finished, in 2,009, the 8th wonder of the world.
1．Which is not the purpose to build such a huge dam? ________.
[ ]
A．To prevent floods
B．To produce electricity
C．To improve the sailing conditions
D．To make it a wonder
2．Compared with the High Dam at Aswan, the Three Gorges Dam is ________ metres wider at the base.
[ ]
3．Where does the dam lie? ________.
[ ]
4．Some scientists fear that ________ when the dam is built.
[ ]
A．the ecological balance will be destroyed
B．large ships will destroy the dam
C．the Yangtze River may be too crowded
D．the amount of electricity will not be as much as expected
5．Which of the following is not true according to the passage? ________.
[ ]
A．China will be able to depend on the Yangtze River, the third largest river in the world, for electricity
B．Chongqing will become one of largest inland ports in the world
C．The dam will cause serious pollution
D．The dam will tame the Yangtze River

1．D 细节理解题。建设这座大坝的目的是为了防洪A，发电B，改善航运条件C等水利资源的综合利用，而D即使它成为世界一大奇迹则不是目的。所以D是该题的正确答案。有的同学选此类题时忽略了审题，即把Which is not the purpose to build such a huge dam？理解为Which is the purpose to build such a huge dam？结果所选答案可能是A、B、C中的任意一个，作这类题切勿在审题时粗心大意。 2．A 观察计算题。阿斯旺（Aswan）大坝长980米，长江三峡长6860米，所以长江三峡大坝比阿斯旺长5980米，该题答案为A。 3．D 观察思考题。大坝位于何处，由短文第二段最后一句并结合图示可判断出，此坝位于宜昌附近的三都坪，故答案应选D。 4．A 观察题。一些专家断定，三峡工程的兴建会破坏沿江两岸的生态环境，污染水库、於积河床等，A为其中的一种情况，故应选A。 5．C 细节理解题。根据短文推断，A中国将利用长江之水发电，B大坝建成后，重庆将成为内陆港，D驯服洪水都是建坝的目的，只有C（大坝建成后将带来严重污染）不是建坝的自的，故答案应选C。 |
