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

17.SometimeSometime解析：通過對后面句子的分析，我們可以知道那些想入非非、飄飄欲仙的人有朝一日也是可以“雙腳落地的”，那就是“sharpwordsfromteacher”，所以這里表示的是“有朝一日”，故答案為sometime。

18.betweenbetween解析：此句意為“Thomas先生盡管不能在握筆方式和拼寫準(zhǔn)確性之間建立重要的統(tǒng)計(jì)學(xué)聯(lián)系，…”所以答案為介詞between。

19.whatwhat解析：解析同上。這里是一個(gè)名詞性從句，what在句中做主語。故答案為what。

20.nono解析：本句話的意思是“那些趾高氣揚(yáng)的人不可能是那些平易近人的人”。這是否定的意思，故答案為no。

21.thatthat解析：此空后的內(nèi)容為maintain的內(nèi)容，即此空后的句子為maintain的賓語，應(yīng)填一個(gè)可引導(dǎo)賓語從句的詞。

22.suchsuch解析：“such…as”用來舉例子。所以此處應(yīng)填“such”。

23.accordingaccording解析：此句意為“…一項(xiàng)個(gè)性與社會(huì)心理學(xué)的六月雜志的研究?！憋@然，空處應(yīng)填“根據(jù)”。

24.onon解析：focuson意為“集中于”，為固定短語。

25.whowho解析：此空后的句子應(yīng)為teacher的定語從句，故此空處應(yīng)填who，引導(dǎo)修飾人的定語從句。

26.C解析：由C中的第一段最后一句話“Thissourcebook…andprovidespolicyadvice，includingtheuseofcleantechnologiesandenvironmentallysoundproductiontechniques，．．．．”可知。

27.D解析：由文章最后
