| Which of your hands do you use most ? Very few of us use both of our hands well. Most of us are right- handed. Only about five people out of a hundred are left-handed. New-born babies can take things with either of their hands, but in about two years they like to use their right hands. Scientists don't know why this happens. They have studied it. They think our animal ancestors (祖先) are right-handed. This may not be true. Monkeys are our closest relations in the animal world. Scientists have found that monkeys like to use one of their hands more than the other-but it can be either hand. There are as many right-handed ones. Next time you visit the zoo, watch the monkeys carefully. You'll see that some of them will swing (摆动)from their right hands and others will use their left hands. But most human beings (人类) use their right hands better and this makes life difficult for the left-handed ones. We live in a right-handed world. |

Stop! Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noisy. Noise is loud and unwanted sound. Noise can be caused by many kinds of machines, such as motorcycles, jet planes, tractors and so on. And, to some people, rock bands are also noise. What happened to people who live near noisy machines or use them over a period of time? Doctors find that these people have trouble in sleeping, But, most important, constant loud noise can cause a loss of hearing. Scientists use a unit of measure called a decibel 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 can measure over 120 decibels. Noise at this high level causes the greatest hearing loss. 小题1: From the article we know noise is ___________. wanted sound B. loud and unwanted sound C. all sounds that you can hear D. comfortable sound 小题2: A “decibel” is a _________
