Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world's population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis.
But that doesn't have to be the outcome. Water shortages do not have to trouble the world---if we start valuing water more than we did in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want.
Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs.
Governments should also protect this resource by providing water in more economically and environmentally sound (健康的) ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland.
No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate (调整) water policy.
1.What is the real cause of the potentials water crisis.
A. Only half of the world's water can be used.
B. The world population is increasing faster and faster.
C. Half of the world's water resources have been seriously polluted.
D. Humanity has not placed enough value on water resources.
2.As is indicated in the passage, the water problem _________ .
A. is already serious in certain parts of the world.
B. has been exaggerated by some experts in the field
C. poses a challenge to the technology of building reservoirs(水库)
D. is underestimated by government organizations at different levels
3. According to the author, the water price should _______ .
A. be reduced to the minimum B. stimulate domestic demand
C. go with its real value D. take into account the occurrences of droughts
4.In order to raise the efficiency of the water supply, measures should be taken to ______ .
A. guarantee full protection of the environment
B. centralize the management of water resources
C. increase the sense of responsibility of agencies at all levels
D. encourage local and regional water resources

Bond had walked for only a few minutes when it suddenly occurred to him that he was being followed. There was no evidence for it except a slight headache and a little knowing the people near him but believed in his sixth sense and he at once stopped in front of the shop window he was passing and looked occasionally back along 46th Street. Nothing but a lot of miscellaneous people moving slowly on the sidewalks, mostly on the same side as himself, the side that was back from the sun. There was no sudden movement into a doorway, nobody wiping his face with a handkerchief to avoid recognition, nobody bending down to tie a shoelace.
He went on and turned into the Avenue of the Americans, stopping in the first doorway, the entrance to a woman’s underwear store where a man in a blue suit with his back to him was examining the black lace paints on a particularly realistic-dummy（模型）.
And then something grasped his arm and a voice came, “All right, Limey. Take it easy unless you want lead for lunch,” and he felt something press into his back just above the kidney.
There was a tap as his fist was caught in the other man’s left hand, and at the same time as the contact telegraphed to Bond’s mind that there could have been no gun, there came the well remembered laugh and the lazy voice saying: “No good, James. The angles have got you.”
Bond straightened himself slowly and for a moment he could only gaze into the smiling face of Felix Leiter with blank dis-belief, his built-up tension（紧张）slowly relaxing.
“So you were doing a front tail, you bastard（赝品）,” he finally said.
1. Bond realized that he was being followed by means of _____.
A. his common sense B. his sense of humour C. his sight D. his sixth sense

A. most people on the sidewalks were on the same side as himself
B. no one suddenly turned into a doorway
C. a man was looking into the window of a store
D. no one wiped his face with a handkerchief
3. Why did Bond stop in the doorway to the underwear shop?
A. To see who was following him. B. To look at the man in the blue suit.
C. To avoid the sunshine. D. To look at the underwear.
4. What did the man mean by saying “Take it easy unless you want lead for lunch”?
A. Put up your hands.
B. Don’t move or I’ll shoot you.
C. If you want to have lunch, you must listen to me.
D. You go first slowly and we’ll have lunch together.
5. What is “a front tail”?
A. Pretending to be someone else. B. Following somebody from in front.
C. Following someone from behind. D. Standing in front of a shop window.
