　　cet6六級級作文范文：the ups and downs of population growth人口變化

　　the ups and downs of population growth

　　while the problem of the explosively-growing human population has become this century’s focus , the mas s media , during the r ecent decades , have been conveying another sensational is sue near ly to every household — the world’s wildlife extinction . take the u .s . alone for example . during the past one hu ndr ed-odd yea rs , especially f rom 1940 to 1990 , its population has been increasing so rapidly that it has now amounted to 250 million . howeve r , we have, at the same time , surprisingly discovered that the number of wildlife species has been propor tionally decreasing . this is enough to explain what effect“ the ups”of human population has brought to“ the downs”of wildlife population .

　　investigations so fa r made s how that the extinction of wild animals and c reatur es is att ributed to various r easons , the inc reasing h uman occupa tion of space and environmental pollution being the two impor tant factors obviously k nown to everyone . howeve r , in my mind , nowadays the cruelty of killing and eating wild animals is simply beyond conceivability .

　　mer ciles s hunters capture them and then sell them for a good price; greedy vintner s try to procur e the best recipes for dressing the meat to pe rfection and con sequently have their restaurants frequented by fine gentlemen; skillful cook s , who under - stand how to oblige the guests , cont rive to make it as expensive as they please; fashion designer s and tailors make the skin into admirable gloves , shoes , handbags , girdles for rich ladies . in this way , the wildlife cont ribute to the feeding , and partially to clothing , of many thousands .

　　for tunately , the world’s at tention 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 respon sible, the law is r esponsible, and i should , in the sincerity of my hear t , say eve ry human being is r esponsible .

　　cet6六級作文內(nèi)容分析：

　　本文是一篇圖表作文。在閱讀圖表之后, 作者的思路遵循了“事實— 分析— 趨向和建議”的模式。在第一段中先概括了人口增長和野生動物滅絕的情況并按圖中美國為例寫出100多年中, 特別是1940 到1990 年人口的增長。與此同時對照野生動物的滅絕數(shù)量, 得出的結(jié)論是前者的增長導致了后者的負增長。在第二段的原因分析中, 作者表示出對捕殺和食用野生動物的特別反感并以諷刺的筆法抨擊這一破壞生態(tài)的行為。在結(jié)尾段中作者對今后的趨向看好, 同時提出保護野生動物人人有責。本題曾是一考研英語作文題, 作者借題撰文, 全文有較大深度, 適合于考研或雅思、托福的應(yīng)試者。
