About 4% of the population is what scientists call “amusic”. People who are amusic are born without the ability to enjoy musical notes. Amusic people often can’t tell the differences between two songs.

As a result， songs sound like noise to an amusic．Many amuics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. In fact， most people can’t understand what it feels like to be amusic. Just going to a restaurant or a shopping center can be uncomfortable or even painful．That is why many amusics have to stay away from places where there is music．However， this can result in social loneliness．“I used to hate parties，” says Margaret， a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret， scientists are finally learning how to identify(辨别) this unusual condition.

Scientists say that the brains of amusics are different for those of people who can enjoy music. The difference is complex(复杂的)， and it is not connected with poor hearing. Amusics can understand other non-musical sounds well. They also have no problems understanding common speech. Scientists compare amusics to people who just can’t see certain colors.

Many amusics are happy when their condition is finally diagnosed(诊断)．For years， Margaret felt embarrassed about her music problem．Now she knows that she is not alone．That makes it easier for her to explain．“When people invite me to a concert， I just say” No， thanks. “I’m amusic.”says Margret.

People used to wonder how fish can hear sounds without ears. But the fact is that fish do have ears. We can't see the ears because they are inside fish's bodies, and they hear very well with them. Their listening is actually much better than man's.

Many water animals make noises while they are doing something. Sounds are real words for them. By sounds, they know where they are and which way to go. When they face dangers or find food, they always make sounds to tell others the news.

A new field in science is to learn the meanings of underwater sounds. People use the same method that they have used in learning the secrets of birds' calls. But this method is more difficult to use in the sea because many of the sea animals can't be easily followed and studied. But we have no any other better way to study the sounds in the sea. Perhaps the meanings of the calls of the sea animals will be known more clearly someday. It will be useful for us to learn the secrets of the sounds in the sea.

根据短文内容判断正误，正确的写T，错误的写F。

1.Fish have ears outside their bodies.

2.Studying fish's sounds is more difficult than that of birds.

3.Fish can make sounds to tell others the danger they meet.

4.It will be useless to learn the secrets of the sounds in the sea.

5.The passage is mainly about how to study the sounds on the land.
