cet6六级级作文范文：
The ups and downs of population growth
人口变化
While the problem of the explosively-growing human population has become this century's focus, the mass media, during the recent decades, have been conveying another sensational issue nearly to every household — the world's wildlife extinction. Take the US alone for example, during the past one hundred-odd years, especially from 1940 to 1990, its population has been increasing so rapidly that it has now amounted to 250 million. However, we have, at the same time, surprisingly discovered that the number of wildlife species has been proportionally decreasing. This is enough to explain what effect "the ups" of human population has brought to "the downs" of wildlife population.
Investigations so far made show that the extinction of wild animals and creatures is attributed to various reasons, the increasing human occupation of space and environmental pollution being the two important factors obviously known to everyone. However, in my mind, nowadays the cruelty of killing and eating wild animals is simply beyond conceivability.
Merciless hunters capture them and then sell them for a good price; greedy vintners try to procure the best recipes for dressing the meat to perfection and consequently have their restaurants frequented by fine gentlemen; skillful cooks, who understand how to oblige the guests, contrive to make it as expensive as they please; fashion designers and tailors make the skin into admirable gloves, shoes, handbags, girdles for rich ladies. In this way, the wildlife contribute to the feeding, and partially to clothing, of many thousands.
Fortunately, the world's attention has nowadays been shifted to ecological balance. Most people have become aware of the danger of the extinction of wildlife. For the protection of wildlife the government is responsible, the law is responsible, and I should, in the sincerity of my heart, say every human being is responsible .

cet6六级作文内容分析：
本文是一篇图表作文。在阅读图表之后, 作者的思路遵循了“事实— 析—趋向和建议”的模式。在段中先概括了人口增长和野生动物灭绝的情况并按图中美国为例写出100多年中, 特别是1940 到1990年人口的增长。与此同时对照野生动物的灭绝数量, 得出的结论是前者的增长导致了后者的负增长。在第二段的原因分析中, 作者表示出对捕杀和食用野生动物的特别反感并以讽刺的笔法抨击这一破坏生态的行为。在结尾段中作者对今后的趋向看好, 同时提出保护野生动物人人有责。本题曾是一考研英语作文题, 作者借题撰文, 全文有较大深度, 适合于考研或雅思、托福的应试者。
