　　Man and His Environment

　　Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth. He has transformed woodlands and prairies into farms and made lakes and reserviors out of rivers for irrigation purposes or hydroelectric power. Man has also modified the face of the earth by draining marshes and cutting through mountains to build roads and railways.

　　However, man's changes to the physical environment have not always had beneficial results. Today, pollution of the air and water is an increasing danger to the health of the planet. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. The pollution of water is equally harmful. The whole ecological balance of the sea is being changed and industrial wastes have already made many rivers lifeless.

　　Now environmental protection is more pressing than ever before. As we know, massive destruction of environment has brought about negative effects and even poses a great threat to man's existence. Indifference to these problems will mean committing suicide. Therefore, effective measures should be taken and laws passed to conserve environment. Otherwise,man is certain to suffer from the serious consequences caused by this lack of care for his living surroundings.

　　【參考譯文】

　　人與環(huán)境

　　縱觀歷史，人類為了改善生活方式而改變了自己的物質(zhì)環(huán)境。借助于技術(shù)工具，他改變了地球的許多物理特征。他將林地和草原改造成農(nóng)田和河流湖泊和水庫(kù)，用于灌溉和水力發(fā)電。人類還通過(guò)排水沼澤和切割山脈來(lái)修建土地和鐵路來(lái)改變地球的面貌。

　　然而，人類對(duì)物質(zhì)環(huán)境的改變并不總是有益的。今天，空氣和水的污染對(duì)地球的健康構(gòu)成了越來(lái)越大的威脅。每天機(jī)動(dòng)車排放出成千上萬(wàn)噸的氣體。工廠的煙霧污染了工業(yè)區(qū)和周邊地區(qū)的空氣。水的污染同樣有害。整個(gè)海洋生態(tài)平衡正在發(fā)生變化，工業(yè)廢水已經(jīng)使許多河流失去活力。

　　現(xiàn)在環(huán)境保護(hù)比以往任何時(shí)候都更加緊迫。我們知道，大規(guī)模的環(huán)境破壞帶來(lái)了負(fù)面影響，甚至對(duì)人類的生存構(gòu)成了巨大威脅。對(duì)這些問(wèn)題漠不關(guān)心意味著自殺。因此，應(yīng)該采取有效的措施，通過(guò)法律來(lái)保護(hù)環(huán)境。否則，人類肯定會(huì)因缺乏對(duì)生活環(huán)境的關(guān)懷而造成的嚴(yán)重后果。
