竞争无处不在，无时不有，竞争是现代社会存在的突出特征，正确对待并参与竞争是人们立足社会的重要条件。然而我们一部分学生害怕竞争，甚至采取不正当竞争的方法。

根据短文理解，选择正确答案。

    Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk, laugh, and do things with. Surely, sometimes we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend.

    No two people are the same. Sometimes friends don't get on well. That doesn't mean that they no longer like each other. Most of the time they will make up(和解) and become friends again.

    Sometimes friends move away. Then we feel very sad. We miss them very much, but we can call them and write to them. It could be that we could even see them again. And we can make new friends. It is surprising to find out how much we like new people when we get to know them.

    There's more good news for people who have friends. They live longer than people who don't. Why? It could be that they are happier. Being happy helps you stay well. Or it could be that they just know that someone cares. If someone cares about you, you should also take good care of yourself.
