Moreover, a number of newly built factories keep discharging harmful gases and liquids, which seriously pollute the environment. This has disturbed the ecological balance, contributing to the extinction of some wildlife.

   In my view, three strong measures should be taken to solve the problem. In the first place, the birth rate in the U.S. must be put under control because the rapidly growing population leads to serious environmental crisis. Secondly, the U.S. government is supposed to create as many nature reserves as possible where all the native species of wild animals can be kept from being hunted and all the native species of plants can grow vigorously. Last and not least, it is urgent for the authorities to set up a foundation to reward those who do much to protect wildlife. (233 words)

   4. 情景题型写作

   1) 情景题型写作要点

   情景题型写作没有具体题目，仅仅规定一定的情景，这是一种指导性较强的写作题型，考生千万不要脱离情景，而应严格依照题目所规定的情景构思短文。特别注意以下几点：

   ① 情景式写作要求考生在题目规定的情景内展开构思，组织内容。

   ② 仔细审题。考生应明确题目所提供的情景，是论证还是说明，是叙事还是写景。

   ③ 确定段落与主题句。各段的主题句使文章有条有理，同时也使考生对自己所要表达的内容有更具体的把握。

   ④ 平稳地展开段落。主题句一经确定，考生便可以围绕主题句，展开段落，完成全文的写作。段落的展开应该建立在段落情景基础之上，每段的重点都应集中于描述情景规定内容。

   ⑤ 考生的每一词每一句应紧扣情景，突出重点，前后连贯，表达清楚，符合逻辑。

   ⑥ 明确题型种类。情景写作可根据内容写成不同文体，如记叙文、论说文、书信报告等，故考生应该注意灵活运用相应文体的写作方法与技巧。

   ⑦ 认真检查与修改。考生应重点检查是否完全准确地包含了情景所要求的各方面内容，是否有与情景相悖或不相关的内容。

    ① 考试题目：

   Some people hold onto the idea that money and property offer more opportunities for success in our society; others think that education provide more opportunities for success in our society. Present your perspective on the issue, using relevant reasons and/or examples to support your views.

   ② 参考范文：

   Which factor offers more opportunities for success in our society: education or money and property? In my view, education has replaced money and property as the main provider of such opportunities today. I base my view on two reasons. First, education—particularly higher education—used to be amiable only to the wealthy but now is accessible to almost anyone. Second, because of the civil-rights movement and resulting laws, businesses are now required to hire on the basis of merit rather than the kinds of personal relations traditionally common among the wealthy.

   Education always plays a key role in determining one’s opportunities for success. But in the past, good post-secondary education was available mainly to the privileged classes. Because money and property largely determined one’s access to higher education, money and property really were the critical factors in opening doors to success. However, higher education is more egalitarian today. Given our vast numbers of state universities and financial-aid programs, virtually anyone who meets entrance requirements for college can obtain an excellent college education and open up windows of opportunity in life.
