15.A

16.drinkingdrinking解析：由本句句意“通過將污水和化學(xué)物質(zhì)倒入河流和湖泊，我們已經(jīng)污染了我們的…水?！憋@然，此空處應(yīng)為“飲用”。

17.gripgrip解析：顯然，此空應(yīng)填一個(gè)動(dòng)詞“握，拿”，英語中握筆用動(dòng)詞grip。

18.offoff解析：turnoff是“關(guān)掉”的意思，此題考查動(dòng)詞短語的用法，根據(jù)上下文語境，這里意思是“關(guān)掉你的手機(jī)”。所以用副詞“off”。

19.disposedispose解析：由前一句“但是這個(gè)問題因?yàn)槲覀兊摹耙淮涡浴奔夹g(shù)而加劇了?！笨芍?，此處應(yīng)為“丟掉，扔掉”之意，即disposeof。

20.whatwhat解析：此題考查what引導(dǎo)的賓語從句。要注意分析句子中的成分，此空為listento后的賓語。所以此處應(yīng)填引導(dǎo)詞“what”。

21.thoughthough解析：參見47題解析，由本句句意“…更便宜，…它的95％的部件仍可以使用?！笨芍?，此空處應(yīng)填“盡管，即使”，即eventhough。

22.useuse解析：后面的一句話“Theexpressionis‘both-feet-on-the-ground.”表示down-to-earth的另一種表達(dá)方法是both-feet-on-the-ground。而后一種說法是美國人的用法，常常被美國人使用。故答案為use。

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

24.poorpoor解析：此句意為“但是很容易通過給…表現(xiàn)報(bào)酬或創(chuàng)造對(duì)報(bào)酬太…的期望而扼殺創(chuàng)造性。”顯然，此空處應(yīng)填“劣拙的，不好的”。

25.dailydaily解析：此句意為“但是不要使他們的…工作僅僅成為一長串令人心煩的差使?！憋@然，此空應(yīng)填“每日的，日常的”。

26.C解析：由C中的第一段“Lookatthetitleofthemovie．TeamAmerica：WorldPolice．ThisdefinitelysoundslikeAmerica．thebigbrothertotheworld，whetherpeoplewantustobeornot．”可知。

27.D解析：第四段提到基因療法遭受的一起挫折——一個(gè)病人因接受基因療法而死亡；接著講專家擔(dān)心運(yùn)動(dòng)員利用基因在比賽中作弊會(huì)進(jìn)一步tarnish這一領(lǐng)域，從上下文邏輯推理，應(yīng)該是“有損，玷污”這一類的意思，因此正確答案為D。

28.B解析：由B內(nèi)容中的itisrenewable中“NuclearenergyfromUraniumisnotrenewable．”可知答案為B。

29.C解析：由第一段可知NAAFA認(rèn)為肥胖無害，故A項(xiàng)是錯(cuò)誤的。B項(xiàng)文章中未提到。第一段倒數(shù)第二句話說到基因決定人的胖瘦，故C項(xiàng)是正確的。NAAFA只是認(rèn)肥胖對(duì)人體無害，并沒有說有好處，故D項(xiàng)是錯(cuò)誤的。

30.D解析：第二段第一句提到“…butoldwastefulhabitsdiehard”，可知雖然美國人開始回收利用一些物品，但是那種浪費(fèi)的舊習(xí)慣依然
