Water problems in the future will become more intense and more complex. Our increasing population will tremendously increase urban wastes, primarily sewage. On the other hand, increasing demands for water will decrease substantially the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce larger volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever - increasing quantities of agricultural chemicals. From this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problem.

There are two ways by which this pollution problem can be dwindled(减少). The first relates to the treatment of wastes to decrease their pollution hazard . This involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes, or effluents, to permit the reuse of the water or minimize pollution upon final disposal .

A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement. Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Effluents from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are potential economic uses for waste products.

1.The purpose of this passage is ________.

A．to alert the reader to the dwindling water supply

B．to explain industrial uses of water

C．to acquaint the reader with water pollution problems

D．to demonstrate various measures to solve the pollution problem

2.Which of the following points is NOT included in the passage?

A．Industrial development includes the simplification of complex chemical processes.

B．Diluting wastes needs certain amount of water.

C．Demands for water will go up along with the expanding population .

D．Intensive cultivation of land require more and more chemicals.

3.The reader can conclude that _________.

A．countries of the world will work together on pollution problems

B．byproducts from wastes lead to a more prosperous marketplace

C．science is making great progress in increasing water supplies

D．some industries are now making economic use of wastes

4.The author gives substance to the passage through the use of________.

A．interviews with authorities in the field of water controls

B．opinions and personal observations

C．definitions which clarify important terms

D．strong arguments and persuasions

5.The underlined words "prior to"(para. 2)probably man________.

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 were 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, an official in 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 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.

1.People in Shanghai get their daily water mainly from _______now.

A．the underground              B．the Huangpu River

C．the rain                     D．the Yangtze River

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

A．the renovating of family toilets will save plenty of water

B．about half of waste water has been treated already

C．there is plenty surface water and large amount of rain at present

D．advanced technology makes people use water as much as possible

3.Which group of measures are all mentioned in the passage to save water?

a．improve drinking water quality

b．change some industrial structure

c．introduce or use some new technology

d．speed the economic development of Shanghai

e．renovate some family toilets

f．build more sewage treatment factories

A．a, b, c, d           B．a, b, e, f

C．b, c, d, e           D．b, c, e, f

4.We can infer from the passage that ________.

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

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

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

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

In only two decades Asian Americans have become the fastest growing U.S. minority. As their children began moving up through the nation schools，it became clear that a new class of academic achievers was emerging. Their achievements are reflected in the nation’s best universities，where mathematics，science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their education abroad arrived in the U.S. with a solid grounding in mathematics but little or no knowledge of English. They are also influenced by the promise of a good job after college. Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an art degree.

Most Asian-American students owe their success to the influence of parents who are determined that their children take full advantage of what the American educational system has to offer. An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian culture that makes success，such as ideals that stress family values and emphasize education.

Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial image. Many can remember when Chinese, Japanese and Filipino immigrants were the victims of social isolation(隔离). Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.

1.With making outstanding achievements at college，Asian- American students ________.

A.feel they are mistreated because of limited knowledge of English

B.are afraid that their academic successes are not recognized

C.still worry about unfair treatment in society for their origin

D.generally feel it a shame to have to depend on their parents

2.What are the major factors that determine the success of Asian Americans?

A.A solid foundation in basic mathematics and Asian culture.

B.Hard work and intelligence.

C.Parents’ help and a limited knowledge of English.

D.Asian culture and the American educational system.

3.Few Asian American students major in human sciences mainly because ________.

A.their English is not good enough

B.they are afraid they might meet with unfair judgment in these areas

C.there is a wide difference between Asian and Western cultures

D.they know little about American culture and society

4.Why do “both explanations” (Para.3) worry Asian Americans?

A.They are afraid that they would again be separated from American society.

B.People will think that Asian students rely on their parents for success.

C.Asian Americans will be a threat to other minorities.

D.Americans fear the academic achievements made by Asian Americans.

5.Before 1952 in America，________.

A.Asian Americans could not be academically successful

B.there were few immigrants from East and Southeast Asia

C.immigrants were not equally treated by Asian Americans

D.immigrants from East and Southeast Asia were looked down upon
