2010年12月英语四级考试模拟试题答案详解

　　Part I Writing

　　Styles of Living

　　Some people enjoy living together with their parents after the have grown up. They think that by living with parents they can take better care of their parents and vice versa. Meanwhile, they can turn to their parents for help if they get into trouble or have some difficulties. To them, life in a big family seems to be more enjoyable than that in a small one.

　　Others, however, prefer living separately. They cherish the idea of being independent, and wish to have a place of their own. Besides, they don't want to be overprotected by their parents, but long for the opportunities to face the society by themselves.

　　As for me, I like an independent life style. Different generations have different life styles and values. What one generation likes may not be another generation's fondness. In order to avoid conflicts, the best way is to live separately. In addition, by leading an independent life, I can develop my own ability to deal with the difficulties in my life. So I want to live by myself.
