| The earth is about 4,600 million years old. Modern man has lived on the earth for only 35,000 years, but during that time, we have changed our planet in many ways. Many of the things that we have done are good, but more are not good for the earth. Water pollution A lot of people, birds and fish die each day because of water pollution. Factories have polluted the land and the water. As a result, many rivers and lakes are now dead. Air pollution In big cities, factories, as well as cars, trucks and buses are the main cause of air pollution. Many people in cities now have serious health problems.

| 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. | |||
