A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.

A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.

P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.

Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.

The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.

The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.

The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.

1. 　　　　　　 are expected to have severe water problems by the year 2025.

A. 46 countries　　　　 B. 18 countries

C. 28 countries　　　　 D. No countries

2. All the following are true except　　　　　　　　 .

D. Egypt now has enough fresh water

3..What can be inferred from the passage?　　　 .

A. There is connection between providing clean water and slowing population growth

B. Lack of water may also result from international conflict

C. The ability of developing has nothing to do with lack of water

D. It is not known whether diseases have something to do with lack of water

4.The best title of the passage would be 　　　　　　 .

A. World Conflict　　　　　　 B. World Water Shortage

C. Diseases and Water　　　　 D. Population and Water

How do you design a pay plan that motivates people to do their best work? A new study by three Harvard researchers suggests a novel answer: Shortly after you hire new workers, give them a raise.

"Previous research has shown that paying people more than they expect may elicit reciprocity(相互作用) in the form of greater productivity," notes Deepak Malhotra, a Harvard business-administration professor who worked on the study. What he and his colleagues found, however, was that the connection between more pay and extra effort depends on presenting the increase "as a gift—that is, as something you've chosen to do purely as a nice gesture, with no strings attached."

Malhotra and his team studied 267 people hired by oDesk, a global online network of freelancers, to do a one-time data-entry project for four hours. All of the new hires were people in developing countries, for whom hourly wages of $3 and $4 were higher than what they had been making in previous jobs.

The researchers split the group up into three equal parts. One group was told they would earn $3 an hour. A second group was initially hired at $3 an hour but, before they started working, they got a surprise: The budget for the project had expanded unexpectedly, they were told, and they would now be paid $4 an hour. The third group was offered $4 an hour from the start and given no increase.

Even though the second and third groups were eventually paid the same amount, the second group worked harder and produced more—about 20% more—than either of the other two. People in the second group also showed the most stamina, maintaining their focus all the way through the assigned task and performing especially well toward the end of the four hours. Interestingly, the more experienced employees in the high-performing group were the most productive of all, apparently because their previous work experience led them to appreciate the rarity of an unexpected raise.

Contrary to conventional wisdom, Malhotra points out that higher pay, in and of itself, didn't promote productivity: People who made $4 an hour from the beginning worked no harder than those who were hired at $3 and were then paid $3.

To get the most impact from their pay plans, he adds, companies might consider not only what to pay new hires, but when to pay it.

"The key thing is how you present [the reason for an increase]," he says. Doling out extra money could promote productivity most "if you make it clear that the pay raise is something you're choosing to do just because you can. Our theory is that people will reciprocate. If you do something nice, they'll do something nice back."　　

1.Which of the following is true about the research?

A. None of the participants earned more than $4 an hour in previous jobs.

B. 89 of the participants got a $1 wage raise for their high productivity.

C. It was so important that the budget for it was increased in the process.

D. Stamina shown in it was positively related to the amount of money paid.

2.What does the underlined word “stamina” most probably mean?

A. The quality of being intelligent or clever.

B. The quality of doing something difficult or dangerous.

C. The physical or mental energy needed to do a tiring activity for a long time.

D. A particular method of doing an activity, usually involving practical skills.

3.Why did the second group produce more than the other two groups?

A. Because they thought they were better paid than the other groups.

B. Because they were experienced employees from developing countries.

C. Because an unexpected raise reminded them of their previous work.

D. Because they felt they were nicely treated and tried best to repay it.

4.What can we infer from this passage?

A. No pains, no gains.

B. It matters not what we give but how.

C. Honesty is the best policy.

D. Actions speak louder than words.

When international aid is given, steps must be taken to ensure (确保)that the aid reaches the people for whom it is intended. The way to achieve this may not be simple. It is very difficult for a nation to give help directly to people in another nation. The United Nations Organiztion(UNO) could undertake to direct the distribution of aid. Here however rises the problem of costs. Also tied with this is time. Perhaps the UNO could set up a body of devoted men and women is every country who can speedily distribute aid to victims of floods and earthquakes.

More than the help that one nation can give to another during a disaster, it would be more effective to give other forms of help during normal times. A common proverb says, “Give me a fish and I eat for day, teach me to fish and I eat for a lifetime.” If we follow this wise saying, it would be right to teach people from less developed nations to take care of themselves. For example, a country could share its technology with another. This could be in simple areas like agriculture or in more complex areas like medical and health care or even in building satellites. Even small country is able to help less developed nations. Sometimes what is take for granted, like the setting up of a water purification plant or the administration of a school, could be useful for countries which are looking about to solve common problems. It does not cost much to share such simple things. Exchange students could be attached for a number of months or years and learn the required craft while on the site. They can then take their knowledge back to their homelands and if necessary come back form time to time to clear doubts or to update themselves. Such aid will be truly helpful and there is no chance of it being temporary or of it falling into the wrong hands.

Many countries run extensive courses in all sorts of skills. It will not cost much to include deserving foreigners in these courses. Besides giving effective help to the countries concerned, there is also the build-up of friendships to consider. Giving direct help by giving materials may be effective in the short run and must continue to be given in the event of emergencies. However, in the long run what is really effective would be the sharing of knowledge.

1. According to the author, how could international aid reach the victims in time ?

A. By solving the cost problems

B. By solving the transportation problems

C. By setting up a body of devoted people in every country.

D. By relying on the direct distribution of the UNO.

2. What does the author try to express in the underlined sentence ?

A. Providing food is vital

B. Learning to fish is helpful

C. Teaching skills is essential

D. Looking after others is important.

3. The second paragraph is developed mainly _________.

A. by example　　　 B. by process

C. by comparison D. by contrast

4. What can we infer about international aid from the passage ?

A. It is facing difficulties.

B. It is unnecessary during normal times

C. It should be given in the form of materials

D. It has gained support developed countries
