Science and the World’s Problem

　　In saying that the world is at a crossroad s cr eated by science and technology I know I am not the fir st . But mankind cannot afford to hesitate in indecision . T her e is only one choice for us . We must begin to move along the road to a better future for all the peoples of the wor ld and we must do this now .

　　By the end of the 20th century , the population of the world might have been doubled . In at tempting to ensur e food , clothing and a dignified standa rd of life for this enormous host of people we must use every weapon that science and technology can give u s . T her e ar e obvious difficulties for the less developed a reas in doing this — for example, lack of capital , dif ferences in social structur e and inadequate k nowledge .

　　Our st ra tegy to overcome these difficulties must be total . We have to look at wor ld problems as a whole, that is , try to better our under st anding of the complex inte ractions between the multitude of development activities . We already k now the great gifts that science and technology can bestow on all nations . If we ar e made wiser by a con stant appr eciation of the complexities of what we ar e at tempting , the faste r we shall move towa rd s a solution of the really imperative problems that confront us everywhere .

　　結(jié)構(gòu)分析：

　　· 科技的發(fā)展使世界處于十字路口

　　· 解決人口爆炸問(wèn)題必須依賴科技

　　· 科技的進(jìn)一步發(fā)展尚有許多困難

　　--------------------------------------------------------

　　內(nèi)容分析：

　　本文是一篇議論性的說(shuō)明文, 全文論述了科技的發(fā)展帶來(lái)了世界性的問(wèn)題, 而人口爆炸則是最主要的。人口巨增使世界面臨解決“ 生存問(wèn)題”的難題, 因此又必須求助于科技的進(jìn)一步發(fā)展, 但尚有很多困難。本文的難度相當(dāng)于六級(jí)和考研水平。
