Who would you ___________ as your best friend?

2.

根据短文理解选择正确答案。

      Everyone needs friends. Friends bring us happiness and hope in our lives. But the ability to make friends changes from person to person. To some people, making friends is easy, and to others it's very difficult.

      Making friends is a skill, and the first thing is to know how to get on with others.

      If you have trouble in making friends, maybe I can tell you how to do it.

      ★Realize your own good points. You have skills and talents(才能) that others will like.

      ★ Believe that you are a good person and have something nice to share with others.

      ★ Be humourous. Learn to laugh at yourself and your weakness. Remember to smile at others.

      ★ Respect(尊敬) others. Everyone has his own idea. Learn how to listen to others’ ideas without trying to make them accept(接受) yours.

      ★ Be kind. If you are kind to others, they will usually be kind to you. There are hundreds of little things you can do to show your kindness. Open the door for someone. Wave to a friend and so on.

      ★  Don't complain(抱怨). Learn to accept what you can't change, and work hard to change what you can. No one is willing to hear your complaints all the time.

      ★ Never give up. Even if you are faced with some closed-minded people, never give up. And try to find someone who will understand you.
