On a sunny day last August, Tim heard some shouting. Looking out to the sea carefully, he saw a couple of kids in a rowboat were being pulled out to sea.

Two 2-year-old boys, Christian and Jack, rowed out a boat to search for a football. Once they’d rowed beyond the calm waters, a bleach umbrella tied to the boat caught the wind and pulled the boat into open water. The pair panicked and tried to row back to shore. But they were no match for it and the boat was out of control.

Tim knew it would soon be swallowed by the waves.

“Everything went quiet in my head,” Tim recalls(回忆). “I was trying to figure out how to swim to the boys in a straight line.”

Tim took off his clothes and jumped into the water. Every 500 yards or so, he raised his head to judge his progress. “At one point, I considered turning back,” he says. “I wondered if I was putting my life at risk.” After 30 minutes of struggling, he was close to yell to the boys, “Take down the umbrella!”

Christian made much effort to take down the umbrella. Then Tim was able to catch up and climb aboard the boat. He took over rowing, but the waves were almost too strong for him.

“Let’s aim for the pier(码头),” Jack said. Tim turned the boat toward it. Soon afterward, waves crashed over the boat, and it began to sink. “Can you guys swim?” he cried. “A little bit,” the boys said.

Once they were in the water, Tim decided it would be safer and faster for him to pull the boys toward the pier. Christian and Jack were wearing life jackets and floated on their backs. Tim swam toward land as water washed over the boys’ faces.

“Are we almost there?” they asked again and again. “Yes,” Tim told them each time.

After 30 minutes, they reached the pier.

35. Why did the two boys go to the sea?

A. To go boat rowing.

B. To get back their football.

C. To swim in the open water.

D. To test the umbrella as a sail.

36. What does “it” in Paragraph 2 refer to?

A. The beach                      B. The water.

C. The boat.                        D. The wind

37. Why did Tim raise his head regularly?

A. To take in enough fresh air. 

B. To consider turning back or not.

C. To check his distance from the boys. 

D. To ask the boys to take down the umbrella.

38. How did the two boys finally reach the pier?

A. They were dragged to the pier by Tim.

B. They swam to the pier all by themselves.

C. They were washed to the pier by the waves.

D. They were carried to the pier by Tim on his back.

One of the world's richest men has taken a close interest in one of man's most basic functions: visiting the toilet.Bill Gates's charitable organization, the Bill and Melinda Gates Foundation, is looking for inventors to design the loo of the future, which, they hope, would improve sanitation for millions of people around the world.

So, what's wrong with the traditional flush toilet? Firstly, it wastes a huge amount, of potential drinking water.Secondly, they are more likely to cause pollution.This is a real problem in many areas of the developing world, where, according to United Nations estimates, unsafe sanitation causes half of all hospitalizations.Younger people are particularly at risk.Illnesses which cause diarrhea are responsible for the deaths of about 1.5 million children a year.Finally, standard lavatories simply aren't practical in remote areas.

The challenge set by Bill Gates was to come up with a latrine which works without running water, electricity or aseptic tank.It also needed to operate for less than 5 cents.28 designs were displayed at the recent Reinvent the Toilet Fair.in Seattle, USA.Among them was one which turned human waste into electricity using microwaves, another which converted human waste into charcoal, and yet another which used urine for flushing.

But the winner was a solar-powered design which generated hydrogen gas and electricity.The team from the California Institute of Technology(CIT)picked up a prize of $ 100,000.

But clearly Bill Gates doesn't feel he's flushing money down the toilet.After the Seattle event he said, "We, couldn't be happier with the response we've gotten," Gates has even pledged $370 million more to the future toilet project.They hope to field test more, prototypes over the next three years.

1.Why is Bill Gates paying people to invent new toilets?

A.Because he wants to test people's sense of creativity.

B.Because he thinks the traditional ones are out of fashion

C.Because he wants to improve sanitation for many people.

D.Because he can't design this kind of things himself.

2.Which of the following is NOT a problem with the traditional flush toilet?

A.They are too complicated to use.                 B.They waste too much water

C.They might cause diseases.                          D.They are not always practical.

3.The underlined word "latrine" in the third paragraph might have similar meanings to the word "__    " in the text.

A.sanitation          B.loo            C.diarrhea       D.prototype

4.The team from CIT won the prize because their design         .

A.can change human waste into electricity

B.can turn human waste into charcoal

C.can use urine for flushing

D.can produce power with solar energy

5.If someone "flush money down the toilet", they are        .

A.wasting money for nothing

B.being angry with their work conditions

C.showing—off their wealth

D.expressing their great determination
