At first sight, the fate of threatened species might seem apart from the economy. However, upon a little examination, we will understand the connections between the two. The "good health" of natural systems is a precondition for the "good health" of our social and economic systems. Can one say that a society is thriving when it is exposed to air and water pollution and endures related health problems? Equally, can a society "function" if a large proportion is unemployed or cannot make ends meet? What is the purpose of the first paragraph? A To highlight the importance of healthy social and economic systems. B To clear a misunderstanding about the fate of endangered species. C To illustrate how air and water pollution can cause health problems. D To reveal the connections between natural systems and the economy.

题目解答
答案
解析
考查要点:本题考查学生对段落写作目的的判断能力,需要结合文章内容和修辞手法,理解作者的意图。
解题核心思路:
- 明确段落主旨:段落通过对比和反问,强调自然系统与经济、社会系统的关联。
- 抓住关键句:首句提出“自然系统与经济看似无关,实则相连”,后文通过反问句强化这一观点。
- 排除干扰项:需区分“强调经济健康”与“揭示两者联系”的差异。
破题关键:
- 反问句的作用:通过反问引导读者思考自然系统受损对社会经济的影响,突出联系。
- 段落结构:从“表面无关”到“实际相连”,层层递进,最终揭示核心关系。
选项分析
选项A
“强调健康的社会经济系统的重要性”
- 错误原因:段落确实提到社会经济的“健康”,但其目的是通过反面例子(污染、失业)说明自然系统是经济健康的基础,而非单纯强调经济本身。
选项B
“澄清濒危物种命运的误解”
- 错误原因:段落仅用“濒危物种”引出话题,重点不在解释其命运,而是通过此现象引出自然与经济的联系。
选项C
“说明污染如何导致健康问题”
- 错误原因:污染和健康问题仅作为反问句中的论据,目的是支持“自然系统受损影响经济”,而非单独讨论污染的危害。
选项D
“揭示自然系统与经济的联系”
- 正确原因:
- 首句点题:明确指出“自然系统是经济健康的前提”。
- 反问强化:通过反问句说明自然系统受损(污染、失业)会导致经济无法正常运作。
- 逻辑连贯:段落从现象到本质,层层递进,最终揭示两者关系。
