The amount of water in the world is finite(有限的). The number of people is growing fast and water use is growing even faster. Global water consumption rose six times between 1900 and 1995—more than double the rate of population growth.

As important as quantity is quality—with pollution increasing in some areas，the amount of useable water declines.

And the wider effects of water shortages are just as frightening as the prospect of having too little to drink.

Seventy percent of the water used worldwide is used for agriculture. Much more will be needed if we are to feed the world's growing population. And consumption will rise further as more people expect Western-style lifestyles and diets—one kilogram of grain-fed beef needs at least 15 cubic metres of water，while a kilo of cereals(谷物)needs only up to three cubic metres.

New technology can help，however，especially by cleaning up pollution and so making more water useable，and in agriculture，where water use can be made far more efficient.

Drought-resistant(抗旱的)plants can also help.

The optimists say“virtual water”may save the day—the water contained in crops which could be exported from water-rich countries to dry ones. But the amounts involved would be huge，and the energy needed to transport the water would be enormous(巨大的).

In any case，it is not just us who need water，but every other species that shares the planet with us. We have to rethink how much water we really need if we are to learn how to share the earth's supply. While dams and other large-scale schemes play a big role worldwide，there is also a growing recognition of the value of using the water we already have more efficiently rather than harvesting ever more from our rivers. For millions of people around the world，getting it right is a matter of life and death.

1. Which of the following statements on water consumption is NOT true?

A. Agriculture consumes more than haft of the water used in the world.

B. The growing population worsens the water shortage situation.

2. “Virtual water” refers to the water that ________?

A. is hidden in crops

B. is saved in agriculture

C. can be transported

D. can be reused with the aid of the Internet

3. In the last paragraph，the author mainly ________.

A. criticizes big projects such as dams

B. criticizes the use of river water

C. calls for the protection of other species

D. calls for the more efficient use of water

4. What's the main idea of the text?

A. Water is mainly wasted in agriculture.

B. Water pollution is threatening our health.

C. Shortage of water is a very serious problem.

D. Population growing influences water use.

In some countries where racial prejudice is acute, violence has so come to be taken for granted as a means of solving differences that it is not even questioned. There are countries where the white man imposes his rule by brute force; there are countries where the black man protests by setting fire to cities. Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence—as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch(关键时刻), we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instincts remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learned that violence never solves a problem but makes it even acute. The sheer horror, the bloodshed(流血), the suffering mean nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us.

The truly reasonable men who know where the solutions lie are finding it harder and harder to get a hearing. They are despised, mistrusted and even persecuted by their own kind because they advocate such apparently outrageous things as law enforcement(执行). If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the slums and ghettos, at improving living-standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is sapped by having to mop up the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social programme. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law.

5. Recorded history has taught us ________.

A. violence never solves anything

B. nothing

C. the bloodshed means nothing

D. everything

6. It can be inferred that truly reasonable men ________.

A. can't get a hearing

B. are looked down upon

C. are persecuted

D. have difficulty in advocating law enforcement

7. According to the passage, the best way to solve race prejudice is ________.

A. law enforcement

B. knowledge

C. nonviolence
