根据短文内容, 从下框的A-F选项中选出能概括每一段主题的最佳选项。选项中有一项

为多余项。

A. The water supplying situation in Beijing

B. Water wasting in businesses

C. The consequence of the fierce drought in southeast of China

D. The efficient measures saving water

E. Much water is wasted from the old water facilities

F. Some of the businesses should be forced to close up to save water

1. ________

    The most severe drought in more than a century ravaging Southwest provinces should serve as a

reminder to other parts of the country that they need to get prepared to avert the dangers from the

water crisis, with more than 400 cities in need of water.

2. ________

     Beijing is a case in point. With per capita water resources of only 180 cubic meters, shortage of

water has been a permanent scourge(天灾). And what the city has done in saving on water is far

from enough.

3. ________

     A total of 220,000 tons of fresh water are wasted in flushing toilets every day. The amount of water

leaking in a year from the old water supply pipelines is estimated to be about 70 Kunming Lakes at the

Summer Palace. The 9,000 carwashing shops consume as much as 30 million cubic meters of water a

year.

4. ________

     In addition, the 38 golf courses around the city use 20 million cubic meters of water a year. And at

least more than a million tons of water are needed to make artificial snow for the ski runs in the city's

suburbs. The amount of water consumed by the more than 1,000 bathhouses is estimated at nearly 20

million tons.

5. ________

     This situation is similar in other cities badly in need of water. There is much we can to do to save

water. Of the 100 residential communities that have pipelines for treated water in Beijing, only 20

percent are using it to flush toilets. Why do we need so many golf courses to waste the precious fresh

water? Why do we allow carwashing shops to waste fresh water rather than treated water to wash

cars? Why does the government allow so many bathhouses and ski runs to operate?

All these businesses are making money at the expense of our precious resource of fresh water. We can't

afford to wait until it is too late. Do whatever we can to save water.
