16.withoutwithout解析：此處意為年輕人更喜歡沒有重大責任的簡單工作。所以此處應(yīng)填“without”。

17.diddid解析：據(jù)38題解析，由于while意為“盡管”，才有后面起強調(diào)作用的did，意為“確實”，言下之意有轉(zhuǎn)折之意。

18.closeclose解析：顯然，不好的習慣是“太靠近桌子”，故應(yīng)填“近”。

19.accordingaccording解析：accordingto為“依據(jù)”，為固定短語，意為國的民意調(diào)查”。所以此處填according。

20.purposepurpose解析：從文中的第一句話“Themostobviouspurpose…”可以看出后面還有別的目的，而不是僅僅有最明顯的目的。故答案為purpose。

21.lookinglooking解析：與介詞for的固定搭配，意為“尋求…”，這里指的是尋求新的價值觀。所以此處應(yīng)填“l(fā)ooking”。

22.themthem解析：本題考查代詞的用法，根據(jù)上下文，此處句意為“人們使用這些小玩意兒?！鄙衔囊呀?jīng)提到gadgets，所以這里用代詞“them”代替。

23.whichwhich解析：此空后的句子應(yīng)為定語從句，修飾“tokeneconomies”，故此空應(yīng)填一個可引導定語從句的詞，而且前面可加介詞in。

24.notnot解析：此空前半句意為“我們真地生活在污染中，呼吸著它”，而后半句意為“它開始…我們的健康、幸福和文明?！憋@然，
