→ Step 5 Summary and Homework
In this period, we have learned the advantages and disadvantages of the building of the Three Gorges Dam. It is about our country and life, so it is important for us to get more information about them. Also there are some important words and expressions in the passage.
Homework:
Read the passage and choose the right answers.
(Show the following on the blackboard. )
The Largest Engineering Project
The Three Gorges Dam, the largest dam in the world 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, making electricity and power much of eastern and central China with its 18 200 megawatts electricity. It will create a huge, deep-water lake, and make it possible for 10 000-ton ocean-going ships to sail 1500 miles inland from the Pacific to the city of Chongqing with its 15 million people, making it the world’s largest seaport.
Construction has already started. The dam will be about 6860 feet wide and 611 feet high, at a spot called Sandouping near Yiehang.
It is obvious that such a grand project will do a great deal of good. Most important is flood control. By building a dam instead of new coal plants to meet its growing demand for electricity, China will give off much less poisonous gases into the air.
However, some scientists don’t agree to the project. They say that Chongqing and dozens of other cities along the river will put much waste into the lake, which can do harm to people, fish and other living things that depend on the river. Sedimentation(沉积), the damage of a breach are problems, too.
The Three Gorges Dam could be considered, when it is finished in 2009, a new eighth wonder of the world as to size alone.
1. Which is not the purpose to build such a huge dam?
A. To make electricity.
B. To prevent floods.
C. To improve navigation(航运).
D. To make it a wonder.
2. Where does the dam lie?
A. Near Chongqing.
B. Near Yiehang.
C. In Chongqing.
D. In Wuhan.
3. It will take about_____________ to complete the dam.
A. 10 years
B. more than 10 years
C. half a century
D. a century
4. Some scientists fear that_____________ .
A. when the dam is built, the balance of nature may be destroyed
B. large ship will destroy the dam
C. the Yangtze River may be too crowded
D. electricity will not be as much as expected
5. According to the passage, which of the following statements is NOT right?
A. China will depend on the Yangtze River, the third longest river in the world, for electricity.
B. People have different ideas about the setting up of the dam.
C. It will take many years to build the dam because people want to see whether it will be safe and strong enough.
D. Chongqing will become the largest port in the world when the dam is finished.
