every living thing.

black and grey smoke. This kind of smoke, when mixed with air, is dangerous to our health because it contains

阅读短文，选择正确答案。     Do you get enough sleep? With so much homework it"s often difficult to get the rest you need. But you need
to try, because sleep keeps you healthy and it stops you getting fat.
     Recently, a group of US scientists did a study (调查) of kids aged between8 and 13. The study found that if

根据短文内容，判断正(T)误(F)。
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. ( ) 1. According to the passage, noise is all sounds that you can hear. ( ) 2. A "decibel" is a machine that makes loud noise. ( ) 3. Loud noise can help people sleep better. ( ) 4. Not all people think that rock music is a noise. ( ) 5. We can infer (推断) from the passage that noise is a serious problem.
