【正确答案】Friendship is important to us. Everyone needs friendship. In all our lives, we cannot live without friendship just as we cannot survive without air and water. Friendship gives us a feeling of security and warmth. But real friendship is not easy to come by. True friendship must be sincere and unconditional. It is based on mutual understanding, not on mutual benefit. Some people try to get back something from their friends, and their friends also try to make use of them. If such a relationship can be called friendship, we need no friends at all. The mutual understanding between two friends means both of them have similar ideas and trust each other. Otherwise, it is impossible for them to help each other and to make their friendship last long. As an old saying goes: "A friend in need is a friend indeed", so real friendship should be able to stand all sorts of tests. However, it is advisable to have as many good friends as we can. A good friend can always be a good teacher to us. By his advice, we are persuaded to go the fight way; by his help, we can be free from many difficulties; by his warning, we are aware of the danger of doing something wrong. Therefore, the more friends we have, the more help we can expect from them; and the more pleasure we can share with them. And we will see our lives as being beautiful, because we can find friends, everywhere, all our lives.
