大學(xué)英語(yǔ)作文：Air空氣

　　The air surrounding us is important to everyone.Without air, we could not exist.Everyone understands that.But air is necessary in many other ways――ways that are not always so obvious or widely known.

　　我們周圍的空氣對(duì)大家都很重要。沒(méi)有空氣，我們就無(wú)法生存。每個(gè)人都明白這一點(diǎn)。但是在很多其他方面――那些不大明顯或不大為人所知的方面，空氣也是必不可少的。
