Probably the best way to make and keep friends is to find others who share your interests. Lasting friendships often develop between people who enjoy the same activities. You also want to be with friends who share your values and goals for life.It just depends on what your own interests are.
That old saying is also true—the best way to have a friend is to be a friend. Reach out to the others who share your interests, sit with them at lunch, invite them to join you in the activities you all like, listen to their thoughts and tell them yours. Being a real friend takes time and effort. With time and effort, I'm sure you will find some very good friends during your school years and yon'll always be in touch after leaving school.
Yours，

文章大意：Mike想结交一些新朋友，故写信向Mr Black寻求建议，Mr Black给了他一些如何交朋友的建议。
21．Why does Mike want to leave his old friends?
A．Because they try to make him smoke and drink.
B．Because they have formed some bad habits.
C．Because they no longer want to spend time with him.
D．Because they have never treated him as a good friend.
答案：B 推理判断题。根据Mike信中的“Now they're all getting into smoking and drinking. I want to find a new group of friends”可推断Mike之所以想离开他原来的那些朋友，是因为他们养成了吸烟、喝酒的坏习惯。
