16.threatenthreaten解析：由33题解析可以知道此空一定为“威胁”之意。

17.nono解析：本句话的意思是“那些趾高气扬的人不可能是那些平易近人的人”。这是否定的意思，故答案为no。

18.itit解析：本句意为“‘污染’意思是弄脏——表层土或什么东西，通过引进杂质，这使…不健康或不干净。”显然，此空处应指topsoilorsomething，因为前面已出现，所以用it来代替。

19.whichwhich解析：“声誉建立的基础”英语表达为“thefoundationonwhichreputationsarebuilt”，which指代foundations。

20.drinkingdrinking解析：由本句句意“通过将污水和化学物质倒入河流和湖泊，我们已经污染了我们的…水。”显然，此空处应为“饮用”。

21.onon解析：focuson意为“集中于”，为固定短语。

22.withwith解析：根据对等关系，这里应该与后面的部分“apersonwithagoodunderstanding”相对应。意思是“那些脚踏实地的人往往是那些很了解现实的人。”故答案为with。

23.thoughthough解析：本句话的意思是“尽管知道顾客们可能不知道自己为什么买了这些商品，但是卖家却知道怎么
