Many places in the world need more fresh water than they already have. Every country is trying to find ways to turn salt water into fresh water.

In some places, the sun isn’t hot enough or it does not shine every day. In such places, people get fresh water from the sea by heating the sea water. This way costs more money, but it works faster than the sun.

And heating isn’t the only way to get fresh water from salt water. People are trying some other ways. One way is to cool the sea water below zero. The fresh water will turn into ice first. Take the ice out. That’s the fresh water you want.

Which way is the best? The one that produces the most fresh water with the lowest price. There may be a different way for each place.

Mr. White works in an office.

One morning he was still sitting at the breakfast table and reading newspapers at five past eight. He didn’t seem to be in a hurry and asked his wife for another glass of milk. “Another glass?” his wife asked, “but aren’t you going to the office today?” “The office?” he looked up from his newspaper and said in surprise, “am I not in my office?”

The students were having their chemistry class. Miss Li was telling the children what water was like. After that, she asked her students, “What is water?” No one answered for a few minutes. Miss Li asked again, “Why don’t you answer my question? Didn’t I tell you what water is like?”

Just then, a boy put up his hand and said, “Miss Li, you told us that water has no color and no smell. But where to find such kind of water? The water in the river behind my house is always black and it has a bad smell.” Most of the children agreed with him.

“I’m sorry, children,” said the teacher, “our water is getting dirtier and dirtier. That’s a serious problem.”

Stop and listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound.

Noise can be caused by many kinds of machines, such as motorcycles, jet planes (喷气式飞机), farm tractors, and power motors. And, to some people, rock music is also a noise.

What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. And most importantly, constant (连续的) loud noise can cause loss of hearing.

Scientists use a unit of measure called a decibel(分贝) to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands measure over 120 decibels. Noise at such high level causes the greatest hearing loss.

根据短文内容，判断正(T)误(F)。

31.(　 )According to the passage, noise is all sounds that you can hear.

32.(　 )A “decibel” is a machine that makes loud noise.

33.(　 )Loud noise can help people sleep better.

34.(　 )Not all people think that rock music is a noise.

35.(　 )We can infer (推断) from the passage that noise is a serious problem.
