    I think that a great friend is a great artist who can change my feeling about life greatly. When I talk about the person who influenced me most. I must think of my best friend quickly.

    When I was in my university, one of my classmates sat beside me. His name is Wang Tao. He is my unforgettable friend in my life. He is good at study and handsome. Everyone knows that he is a genius(天才) of my university.

    He is kind hearted and is always ready to help others. But he doesn't like others to praise him, because he think what he did is common. There is an old saying: A friend in need is a friend indeed. Wang Tao sets a good example in many parts in my life.

    I remembered that my mathematics was mediocre at that time, but he was excellent in solving mathematics questions. He often received high scores. Of course, I wished I could reach at his level. Since we talked all day long, he was patient and polite to answer my mathematics questions. Slowly, I made great progress in mathematics. I passed the examination finally. Then we became friends naturally. And now, I still remember his strong will to study.

We know that we live in a society, so we need a lot of friends. There are two kinds of friends, good and bad, bad friend may make our life failed, while good ones make our life successful. To me, Wang Tao is a very good friend. I learned so many advantages from him, and I changed more and more excellently.

    We separated three months ago. Now I miss him very much, and I hoped that our friendship will continue to be just as strong after we graduate（毕业）.

阅读《安恩和奶牛》选段，完成后面小题。
       她就用这副神情接连打发走了许多主顾，这便理所当然地引起大家对她的注意，对她说长道短起来。有个人已经来过一次想买这头牛，遭到了拒绝，现在又折回来，出了一个大价钱，那诱惑力简直令人难以抗拒。安恩老太太还是用非常坚定的口气回答说：“不!”但是她似乎有些窘迫不安。
       “那么，它是已经卖出了不成?”那人问道。
      “没有，这头牲口是不卖的。”
      “是吗?那么干吗老站在这里?难道光是让这头奶牛出出风头吗?”这个男人刨根究底地追问着，“是你自己的奶牛吗?”
      “是呀，当然是的喽。”在这头奶牛还是条小牛犊的时候，就是她的了，那是一点都不假的。安恩想，要是同他多说上几句话能够消消他的气的话，那就不妨多同他闲聊一会儿。
       可是他打断了她：
      “难道你站在这里就为了拿大伙儿开心吗?”
      天哪，怎么能这么说呢！安恩老太太气愤得说不出话，神色有点慌乱。她收起毛线针，从牛角上解下拴牛的绳索，预备回家去了。在这个时候，她睁大了眼睛，用恳求的眼神看着那个人。
       “这头奶牛太孤单了！”她终于吐露了真情，“我的小村庄就只有这么一头奶牛，它又没法同别的牲口在一起，所以我就想到不如把它带到集市上来，至少可以让它跟同类聚聚，散散心。是这样的，真的，我就是这么想的。我的打算没有什么不好的，不会对别人有什么恶意……这样，我们就到这里来了。但是我们不是来做生意的。既然已经弄成这样，我们只好回去了。不过，我刚才应该讲一句‘对不起，我很抱歉’。好吧，再见了，谢谢你。”
