C. Fill in the blanks with proper words.

For some people, music is no fun at all. About four percent of us are what scientists call amusic. Those amusics are born without the ability to r1.  , repeat or remember musical notes（音调）. Amusic people often cannot tell the difference between two songs. Amusics can only hear the difference between two notes if they are pretty different.

As a result, songs sound like n 2.to an amusic. Many amusics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. Their unfitness to enjoy music makes them away from others.

It can be difficult for other people to get to know them. Actually, most people cannot understand what it feels like to be  an amusic. Many amusics may not feel very c3.when they go to a restaurant or a shopping mall. Sometimes they even feel painful. That is why many amusics usually stay away from places where there is music. “I used to h4.parties,” says Margaret, a seventy-year-old woman who only discovered that she was an amusic last month. By studying people like Margaret, scientists  are f 5.learning how to find this unusual condition.

Scientists say that the brains of amusics are different from the brains of people who enjoy music.

The difference isn’t about defective hearing（听力障碍）.

Many amusics are happy when their condition is found. For years, Margaret felt embarrassed about the p 6. with music. Now she knows that a large number of people are like her. There is a name for the condition. That makes it e 7.for her to explain“When people invite me to a concert, I just say‘No thanks, I’m amusic,’”says Margaret.“I just wish I had learned to say that when I was seventeen and not seventy.”
