　　cet6六級(jí)級(jí)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(jí)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(shí)— 分析— 趨向和建議”的模式。在第一段中先概括了人口增長(zhǎng)和野生動(dòng)物滅絕的情況并按圖中美國(guó)為例寫出100多年中, 特別是1940 到1990 年人口的增長(zhǎng)。與此同時(shí)對(duì)照野生動(dòng)物的滅絕數(shù)量, 得出的結(jié)論是前者的增長(zhǎng)導(dǎo)致了后者的負(fù)增長(zhǎng)。在第二段的原因分析中, 作者表示出對(duì)捕殺和食用野生動(dòng)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(duì)今后的趨向看好, 同時(shí)提出保護(hù)野生動(dòng)物人人有責(zé)。本題曾是一考研英語(yǔ)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。
