Key to Model Test Two

　　Part I Writing

　　【写作思路】

　　本文是一篇关于代沟的论文。从代沟的现象开始讨论，接着提出代沟产生的家庭原因以及社会原因。

　　【参考范文】

　　Generation Gap

　　Generation gap seems a hot topic between the old and the young. Parents complained that children didn’t show them proper respect and obedience, while children complained that their parents didn’t understand them at all. Often they discover that they have very little in common.

　　One cause of the generation gap is the opportunity that young people have to choose their own life. In traditional societies, children live in the same area as their parents, marry people their parents know and approve of, and often continue the family occupation.

　　In our society, people often move out of the home at an early age, marry or live with people their parents have never met, and choose occupations that are rather different. Parents often expect their children to be better than them. However, these ambitions for their children are another cause of the division between them.

　　Finally, the speed of change in our society is another cause of it. In a traditional culture, people are valued for their wisdom, but in our society the knowledge of a lifetime may become out of date.

　　No doubt, the generation gap will continue to be a feature of our life. Its causes are rooted in the freedoms and opportunities of our society, and in the rapid pace at which society changes.

　　3. 【解析】N由文章第四段可见本题是错误的。The United States ranks somewhere in the middle of the major countries in landfill disposal.美国出于这些国家的中间位置。
