完形填空 先通读下面的短文，掌握其大意，然后从下面四个答案中选择可以填入相应空白处的最佳答案。（本大题共10分，每小题1分） Do you have many friends in this busy and noisy world? I think you can give me your answer without thinking for a minute. Friendship is so 1 that no one can live if he has no friends. One is happy to have a good friend to talk, laugh, and do some other things with. Everyone will feel 2 if he has no friends. Maybe you will say that sometimes friends quarrel (争吵)with each other, but it doesn't matter. That doesn't mean they no longer 3 each other. They will make up and become 4 again. If our friends go to another place, we will feel very sad. We 5 them very much, but we can 6 them or write to them. Maybe we will never see them 7 . And we can make new friends. It is surprising to find out 8 we like new friends when we get to know them. There is more good news for people who have friends. They live longer than people who have no friends or have few friends. Why? Perhaps because they are 9 . Being happy helps you keep healthy. If you know someone cares about you, you 10 take better care of yourself. Do you think so?
