16.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。

17.importantimportant解析：從本句后面的一句話可以看出，Adown-to-earthperson就算是重要的人物，他們也不會(huì)把這種顯赫寫(xiě)在臉上。所以前面應(yīng)填important。故答案為important.

18.whosewhose解析：這是一個(gè)后置定語(yǔ)從句，用whose來(lái)引導(dǎo)，表示mind與dreamer的所屬關(guān)系。故答案為whose。

19.rewardreward解析：通篇文章均是在講報(bào)酬與創(chuàng)造性的關(guān)系，此句意為“如果孩子們知道他們?cè)跒椤ぷ?，…。”顯然，此空處應(yīng)填“報(bào)酬”。

20.itit解析：本句意為“‘污染’意思是弄臟——表層土或什么東西，通過(guò)引進(jìn)雜質(zhì)，這使…不健康或不干凈?！憋@然，此空處應(yīng)指topsoilorsomething，因?yàn)榍懊嬉殉霈F(xiàn)，所以用it來(lái)代替。

21.worseworse解析：“the+比較級(jí)，the+比較級(jí)”，意為“越…越…，”根據(jù)上下文，本句句意為“身邊的小玩意兒越多，事情似乎就會(huì)變得越糟糕。”所以此處應(yīng)填“worse”。

22.callscalls解析：此句意為“他把這種缺乏禮節(jié)的行為稱(chēng)作是一種無(wú)意識(shí)的無(wú)禮”。call+雙賓語(yǔ)結(jié)構(gòu)，以為“把…稱(chēng)為”，所以此處填“calls”。

23.underunder解析：underguidance意為“在…指導(dǎo)下”，為固定短語(yǔ)。

24.butbut解析：此句意為“30歲的人表現(xiàn)出非常不同的握筆方式，…超過(guò)40歲的人都統(tǒng)一用三個(gè)手指握筆?！憋@然，此空處表轉(zhuǎn)折。

25.thatthat解析：參見(jiàn)32題解析，idea與bigachievementsrarelycomeeasilyandquickly是同位語(yǔ)，故此空應(yīng)填that，引導(dǎo)同位語(yǔ)從句。

26.D解析：由D中“King'sCrossusedtoberenownedforproblemsincludingdrugs，prostitutionandstreetcrime”，意為“KingCross過(guò)去因吸毒，賣(mài)淫和街頭犯罪等問(wèn)題而著稱(chēng)”我們可以看出。所以此處答案為D。

27.C解析：原文對(duì)應(yīng)信息是：“Traditionalscholarships，academicorathletic,arestillapartofmanyfamilies'planning．”意為“許多家庭還在依賴(lài)傳統(tǒng)的獎(jiǎng)學(xué)金，不管是學(xué)習(xí)上的還是體育上的?！彼员绢}應(yīng)選C。

28.A解析：“這些區(qū)別”指的是什么?短文第五段主題句說(shuō)“Butitisn'tallthateasytoexplaintheactualdifferencesbetweenskillsofmenandwomenonthisbasis．”即在此基礎(chǔ)上解釋兩性技能的區(qū)別并不是很容易的事。由此可見(jiàn)，“這些區(qū)別”指的是兩性技能。所以本題應(yīng)選A。

29.C解析：文章第二段對(duì)于基因治療的方式的解釋是用于治療的基因通過(guò)“virusesthatdon'tcausehumandisease”進(jìn)入體內(nèi)，就好像“特洛伊木馬”一樣，由此可見(jiàn)，這些病毒是無(wú)害的。因此正確答案為C。

30.A解析：由A中的最后一句話“…withafictionalTVwitch
