譯文:
As the world is getting more and more densely populated,air pollution has become a severe problem.Air pollution mainly derives from four major human activity sectors: industry,energy,transportation and agriculture.Energies are needed to run factories,to power trains,planes and buses.Nearly all of these energies are produced by burning fuels,which would cause air pollution.Scientists are studying new ways of generating electricity that can be less damaging to the environment.The increased public environmental awareness has led to the advent of activities such as recycling.
解析:
1.隨著世界人口越來越密集,污染已經(jīng)成了嚴重的問題:“隨著”可譯為as,這句話可以用as引導的伴隨狀語從句來翻譯。
2.科學家們正在研究能減少環(huán)境破壞的新發(fā)電方式: 這個句子可翻譯為包含定語從句的句子,new ways是先行詞,引導詞是that。其中“研究”可用動詞study 表示;“發(fā)電”可譯為generate electricity; “減少環(huán)境破壞”即“對環(huán)境的破壞更少”可譯為be less damaging to theenvironment。
