The gigantic dam of the multi-function water ...

The gigantic dam of the multi-function water control facility would be finished nine months ahead of schedule, said an engineer who is in charge of the Three Gorges Project. He said by June, the workers would have built the half-done dam from the southern bank of the river to the height of 185 meters. The Three Gorges Project will be capable of controlling the floods on the Yangtze by then and generating more electricity. And the level of the water stored in the reservoir will rise from 135 meters at present to 156 meters.

Situated near the Xiling Gorge, the easternmost gorge of the Three Gorges on the middle reaches of the Yangtze River, the Three Gorges Dam is designed to have a length of 2,309 meters and a height of 185 meters.

It will also have the functions for flood control, power generation and navigation. It will be built from northern and southern banks of the Yangtze, which has been troubled by floods for hundreds of years.

Launched in 1993, the Three Gorges Project, including the 185-meter-high dam and 26 generators on both banks of the Yangtze, is being built in three phases. The preparations and construction of the first phase were carried out between 1993 and 1997. The Yangtze was dammed at the Three Gorges area for the first time on November 8, 1997.

The entire Three Gorges Project is expected to be completed in 2009 and by then, it will be able to generate 84.7 billion kwh of electricity every year.

63. The underlined word in the fourth paragraph might mean ____.

A. places   B. periods  C. gorges   D. dams

64. According to the passage, we know _______.

the construction will be completed ahead of time

the biggest function of the dam is used to control flood

the Three Gorges Dam will be finished in ten years

the dam will be 156 meters tall when it is finished

65. Which of the following statements is TRUE according to the passage?

A. The Yangtze River was first dammed in the year 1993.

B. The water level in the reservoir will remain at 135 meters.

C. The Three Gorges Dam is on the easternmost part of the river.

D. The first phase of this project is finished in 1997.

A dam is like a wall that is built across a waterway to control the flow of the water.For many years,dams were built only of earth and rocks.Today,many dams are built of concrete.

When a dam is built,water is trapped and held behind the dam.This water forms a lake.The lakes can be used for recreation or for irrigating,or watering crops.The lakes also provide potable water,water that is safe for drinking.This potable water is piped from the lake into houses and other buildings.The lake water further serves as a home,or habitat,for fish and waterfowl.

Dams are often built to provide flood control.Just before the rainy season,the water in the dam is allowed to flow out very slowly.This lowers the water level in the lake so that snowmelt and rainfall can be stored there in every spring and used as needed during the rest of the year.

Some dams are built to use the power of falling water to make electricity.Such dams have powerhouses that contain machines;turbines and generators.Water falls from the lake to the river below the dam.As the water falls,it is sent through the powerhouse.There,the force of the water turns the turbines and generators and produces electrical power needed to light and heat buildings.

1.The word used to describe water that is safe for drinking is 　　 .

A.portable water 　　　　　　 B.dirty water

C.orange juice　　　　　　　　 D.boiled water

2.According to the story,dams are built for different reasons.But all dams 　　 .

A.control the flow of water

B.are built of earth and rocks

C.provide electrical power

D.provide potable water

3.If the water level in the lake behind the dam is not lowered before the rainy season,the 　　 .

A.water in the dam will flow out too slowly

B.snowmelt and rainfall might cause a flood

C.lake will probably dry up

D.water can irrigate

4.When dams are built to provide electricity,which of the following happens first?Water 　　 .

A.is sent through the powerhouse

B.pressure turns the turbines and generators

C.falls from the lake to the river below the dam

D.runs fast

Two-thirds of the world’s major rivers have now been disrupted (中断) with more than 50,000 dams in an attempt to stole water and provide power. In the US, there are more than 85,000 dams, disrupting large and small rives and in most cases transforming natural flow. The most famous of these, the Hoover Dam constructed in the 1930’s, is mainly responsible for the fact that the Colorado River no longer reaches the ocean.

Dams besides all their attractive benefits also have negative impacts. Creating a reservoir means a large area must be flooded. Communities may lose their land, houses and cultural relics. Downstream (在下游方向) of a dam, the flow may be reduced so that farmers cannot irrigate (灌溉) their field.

Environmentally the new reservoir can be a paradise for wildlife especially birds. However it can cause greenhouse gas emissions (排放) and poison the water for fish. Also the dramatic rise and fall of water levels during dam releases is too extreme for plains and animals to cope with resulting in dead zones around the shores of reservoirs. Fish that lay their eggs in the sha Mows for example may find a few hours later that those sites are high and dry.

Dams don’t just block water flow. The flow may be reduced so that farmers will have great trouble getting water for their fields. They also prevent fish migrations and are a barrier to sediment (沉淀物) flows. Instead of rushing downriver sediments get backed up against the dam wall, which cause the reservoir level to increase over time. However, sediments which are rich in nutrients have become a problem. The fertility (富饶) of the entire system can be influenced with soils lost during seasonal rains not being replaced.

Perhaps the biggest problem can be seen in deltas (三角洲) often host to large cities, which are sinking into the oceans. Groundwater is being extracted to feed the city causing the urban weight to sink and sediments washed away by the ocean are no longer being replaced. The result is that sea level rise in cities from Shanghai to Alexandria.

1.What effects does creating a reservoir have on people’s life?

a. People will see fewer birds near the rivers.

b. Farmers below the dam may have less water to irrigate their field.

c. Visitors can’t see some cultural relics anymore.

d. More conflicts and wars over water will break out.

e. All kinds of fish will become extinct in the future.

A.b　 c B.c　 e

C.b　 e D.a　 c

2.With many dams built across rivers fish will______________.

A.find more places to lay their eggs B.feed on more sediment rich in nutrient

C.face a more dangerous living habitat D.find it easier to deal with the rise of water

3.How can dams influence the cities like Shanghai?

A.Its entire system will be influenced. B.It will lie below sea level in the future.

C.The rainy season will last longer. D.Rich soils will be washed away.

4.What does the text mainly talk about?

A.Environmental benefits of dams. B.Cultural loss dam.

C.Economical gain of dams. D.Environmental loss of dams.
