完形填空

Everyone needs friends. We all like to feel close to someone. It is nice       a friend to talk, laugh and do things with. Certainly , sometimes we need to be alone. We don’t always want people     

But we would feel        if we never had a friend. No two people are        . Friends sometimes don’t get on well. That doesn’t mean that they       like each other. Most of the time they will make up (言归于好), and become        again.

Sometimes friends move away. Then we feel very       . We miss them very much, but we can       them and write to them. It could be possible that we could even see them again. And we can also        new friends. There’s more good news for people who have friends. They live longer than people who don’t have. Why? It could be that they are        . Being happy helps you stay well and it could be good just knowing that someone cares about you.
