    Which of your two hands do you use most? Very few of us can use both of hands equally (同样地)well. Most of us are right-handed. Only about five people out of a hundred are left-handed. New-born babies can grasp (抓住)things with either of their hands, but in about two years they usually prefer to use their right hand . Scientists don't know why this happens.

    Scientists have found that monkeys prefer to use one of their hands more than the other__ but it can be either hand. There are as many right-handed monkeys as there are left-handed ones. Next time you visit the zoo, watch the monkeys carefully. You'll see that some of them will prefer to swing (荡秋千)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 those who prefer to use their left hands.We live in a right-handed world.
