16.displaydisplay解析：這里要回應(yīng)本段第一句話(huà)中的“displayed”。在出口結(jié)算處展示的這些小商品無(wú)疑是一種誘惑。這里需要用名詞形式。故答案為display。

17.amongamong解析：此句意為“后一種觀(guān)點(diǎn)得到了許多支持者，尤其…教育家。”顯然，空處應(yīng)填“在…中”，介詞among即有此意。

18.whichwhich解析：由37題解析可知此空應(yīng)為一個(gè)引導(dǎo)定語(yǔ)從句的詞，即which，其后的定語(yǔ)修飾“several(typesofcontamination)”。

19.youngyoung解析：本文均是在講年輕的腦力工作者，故此空所應(yīng)填的用于修飾“collegegraduates”的詞也應(yīng)是“年輕的”。

20.butbut解析：這里表達(dá)的前后句意是一種轉(zhuǎn)折關(guān)系。前面說(shuō)“hemayhavedreams，”而后面“hedoesnotallowthemtoblockhisknowledge…”的意思卻是“但是他也不會(huì)讓這些夢(mèng)想阻擋自己對(duì)什么是現(xiàn)實(shí)的理解。”故答案為but。

21.toto解析：“shift”意為“轉(zhuǎn)變”，“從…到…的轉(zhuǎn)變”應(yīng)該用介詞“to”。所以此處應(yīng)填“to”。

22.areare解析：分析句子結(jié)構(gòu)，這里缺少系動(dòng)詞be來(lái)構(gòu)成動(dòng)詞的被動(dòng)形式。故答案為are。

23.gradesgrades解析：此句意為“…他指出在主要大學(xué)里關(guān)控制評(píng)分標(biāo)準(zhǔn)及恢復(fù)不及格…的努力。”顯然，此空處應(yīng)填“分?jǐn)?shù)”。

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

25.whowho解析：此空后的句子顯然為定語(yǔ)從句，修飾“Behaviorists”，所以應(yīng)填一個(gè)who，引導(dǎo)修飾人的定語(yǔ)從句。

26.A解析：書(shū)評(píng)一中“S
