16.proportionproportion解析：此處意為很大比例的學(xué)生仍然喜歡簡單的工作，所以此處應(yīng)填“proportion”。

17.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。

18.AsAs解析：此句意為“…后一種觀點(diǎn)的例子，…”顯然，空處應(yīng)填“作為”。

19.toto解析：revertto意為“重想，重提”，此句意為“如果你經(jīng)常提到‘我們以前已經(jīng)試著這樣做了，但是不管用’就會很快地挫傷這種好問的頭腦”。

20.knowledgeknowledge解析：前面講商家正確的分析市場的供需信息，知道是什么因素影響顧客的購買欲望。這就是他們利用的信息知識。故答案為knowledge。

21.awareaware解析：beawareof，固定搭配，意為“意識到”。所以此處應(yīng)填“aware”。

22.muchmuch解析：此空處應(yīng)為“太多的”。

23.somesome解析：關(guān)鍵是注意and前后一致?！皊omerationaland…emotional”，前面說促使顧客購買的動機(jī)有很多，有的是理性的，有的卻是沖動。所以這里應(yīng)該是some。故答案為some。
