The quality of drinking water in Shanghai will meet European Union standard by 2010 and, a decade later, citizens in Shanghai will drink the best water in the world.

These we re the goals set out by the Shanghai Water Authority. With the city’s population expected to increase only slightly and the economy to boom by 2020, Chen Yin, and official with the water authority, said Shanghai’s water consumption will not increase from its present amount.

Zhang Yue, director of the Urban Construction Division under the Ministry of Construction, said, “Shanghai is the first city in the country to publicize these ambitions. They will not be easy to achieve.”

He said water saving will help keep the sustainable development of China’s economy.

Saving one cubic meter of water means saving the city’s infrastructure(基础设施)costs by 10,000 Yuan. Last year, Shanghai saved 300 million cubic meters of water either from readjustment of industrial structure or the employment of new technology.

“The aim is to arouse public awareness of the seriousness of water shortages,” Chen said. “The abundant surface water and amount of rain of the city are so misleading that they result in improper use of water.”

Shanghai lacks drinkable water. The Huangpu River, which supplies 80 percent of the city’s drinkable water, is nearing exhaustion.

The city, therefore, has been exploring new sources from the Yangtze River and growing forests along it to conserve quality water.

Besides penning regulations, the authority is popularizing technology among the public to efficiently cut the amount of water used.

At present, the city has 600，000 family toilets, each using 13 liters of water per flush. These are to be renovated(整修)to use only 9 liters of water per flush.

The authority is renovating the first 200 toilets for households – at a cost of 40 Yuan each.

In three years, all the toilets will be renovated, which saves the city nearly 15 million Yuan every year in water conservation.

Another task the city is engaged in is the treatment of sewage(污水)to improve the water environment.

At present the city can only treat 44 percent of its daily 5.04 million tons of waste water. To meet the total demand, 27 more sewage treatment factories are to be established with an estimated investment of 18 billion Yuan.

66.People in Shanghai get their daily water mainly from now.

A.the underground B.the rain

C.the Yangtze River D.the Huangpu River

67.According to the passage, some people have the wrong opinion of using water because .

d.speed the economic development of Shanghai

e.renovate some family toilets f.build more sewage treatment factories

A.a, b, c, d B.b, c, e, f C.b, c, d, e D.a, b, e, f

70.We can infer from the passage that .

A.the boom of economy will need a larger amount of water in the future

B.citizens today in Shanghai drink the best quality of water in the world

C.not everyone today in Shanghai is aware of water shortage

D.all the family toilets will be renovated to save water within 3 years

When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky.

“What excited me most was whether there were planets in other solar systems where life might exist,” he says. “I decided to try to find planets orbiting other stars like our Sun.”

And he did. “My fellow researcher, Paul Butler, and I found our first planet in 1995,” Dr. Marcy says. “We worked for ten years without finding anything! But we stuck with it and our patience paid off.”

Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first “family” of three planets. In June 2002 they announced another discovery: a Jupiter-like planet orbiting star 55Cancri.

At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun.

Why is this important ? Scientists think that life on Earth may exist because of two special features in our solar system. The first is Jupiter.

“Because it’s so big, Jupiter pulls comets and asteroids(小行星), or they all come and hit the Earth.” Dr. Marcy explains. “Without Jupiter , life on Earth would likely have been destroyed.”

A second feature is that Earth is a rocky planet where liquid water, which is necessary for life , can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, “We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life!”

71.What can we learn about Dr. Marcy from the passage?

A. He is fond of watching Jupiter.

B. He is from a scientist family.

C. He dislikes working with Paul Butler.

D. He is interested in finding life in outer space.

72.Which of the following is true of the recent discovery?

A. The planet is not as protective as Jupiter.

B. The planet is close to star 55Cancri.

C. The planet proves to be a gas planet.

D. The planet is as large as Jupiter.

73.Dr. Marcy and Dr. Butler began to find new planets in ____.

A.1995 B.1985 C.2002 D.1981

74.Dr. Marcy thinks that life may exist in the 55Cancri system because ____.

A. he has found the system similar to the solar system.

B. he has discovered an Earth-like planet there.

C. he has discovered a rocky planet there.

D. he has found signs of life in the system

75.“But we stuck with it”( in Paragraph 3) means ____.

A. they felt discouraged B. they carried on with it

C. they failed in their attempt D. they made some progress
