[单选题]柠烯,俗称柠檬精油,它通常被用于制作柑橘香味剂,是很多空气清新剂、身体喷雾剂等芳香剂中途要的化学成分之一。柠烯本身并不可怕,因为该化学物质对人体不会形成大的危害,事实上,它可被用于食品的调味剂。然而柠烯一旦被喷入空气中,很快就会有所变化。研究表明,当柠烯暴露于普遍存在于空气的臭氧中时,两个柠烯分子会形成一个单分子化合物--甲醇。当房间中大量的柠烯被转化成甲醇时,其影响将迥然不同。

[单项选择]Young people in the early 1980s are taking on a set of attitudes and values remarkably different from those of the stormy’ 60s and ’70s. Instead of anti-establishment outbursts, today’s younger generation had turned more thoughtful and more serious. There is heightened concern for the future of the country and a yearning for the traditions and support systems that gave comfort in the past.

It is peer pressure that pushes teenagers into drugs, but
