15.A
16.airair解析:由前面的smog可知,此空處應填與smog相應的物質,又由后面的“hoversovercities”可知,此物質只能是“臟空氣”。
17.tastetaste解析:本句意為“我們看得見它,聞得見它,…它,喝它,而且在它中間掙扎?!庇沙WR可知,此空處只有一個“嘗”較合適。
18.proportionproportion解析:此處意為很大比例的學生仍然喜歡簡單的工作,所以此處應填“proportion”。
19.reasonsreasons解析:本段的第一句話提出問題,問為什么在結算處擺設了那么多的商品。很明顯,后面的文章對這個問題進行回答,并列舉了原因。故答案為reasons。
20.thethe解析:此處缺冠詞,在年輕人之間,用the表示特指。所以此處應填“the”。
21.unlikeunlike解析:根據(jù)下文,以日本學生與美國和韓國的作對比,日本的學生不像韓國和美國的學生一樣。所以此處應填“unlike”。
22.whatwhat解析:解析同上。這里是一個名詞性從句,what在句中做主語。故答案為what。
23.losinglosing解析:根據(jù)上下文的意思,很多年輕一代的日本人已經不再尊重父母,不再對家庭有責任感,所以這里用。losing表示“漸漸失去了”。所以此處應填“l(fā)osing”。
24.customercustomer解析:從這個句子的賓語“…thatheorshehasdoneagoodjobofchoosingtheitems.”可以看出,這里說的是顧客的行為,他們認為自己買這些商品是很理性的。故答案為customer。
25.dividedivide解析:根據(jù)上下文語境,這里是“分為”,divide…upinto意為“把…劃分為”。所以此處應填動詞“divide”。
26.B解析:文章第三段最后兩句話“Moreover,itbecomesunworkable...theInternetdoesnotknowgeographicboundaries,andcompaniesandindividualscannotbeexpectedtocomplywithdiffering,andattimesconflicting,privacyrules.”這說明各州制定的法律是不好實施的,因為網絡是不具有地域限制的。這種法律不能僅僅限制在某個州的范圍之內。故應選B。
27.D解析:由D中的第二段最后一句話“Morethan90percentoftheUniversity’s、full—timefacultymembersholdaPh.D.orterminaldegreeintheirfield”可知。
28.A解析:從文章最后一句話“BecauseofHome’semphasiscrucialtoanystudyofart,thetwentiethcenturyhascometoappreciateBotticelli’sachievements.”可以看出,作者認為波提切利的作品在二十一世紀會被重新的認識,人們會重新認識他作品的成就。故應選A。
29.B解析:由文章倒數(shù)第二段第一句“TheelectriccatfishoftheNileandofotherAfricanfreshwatershasadifferentsystemagainbywhichcurrentpassesoverthewholebodyfromthetailtothehead.”可知。
30.A解析:由A中“TheunpopulararchitecturehasledtotheareabeingcalledmeMiltonKeynesofLondonbutpropertiesarespaciousandunfashionablestyle.haskeptpricesdown”可以看出房屋樣式古板,但是價位令人比較容易接受。所以此處答案為A。
31.C解析:由文章中作者描述聯(lián)合國世界領導人會議的口氣看,他對待該會議的態(tài)度應是critical的。
32.A解析:原文對應信息是:“Even…Tallyadmitsit'salittlescary,especiallysinceshe'llretireandKatiewillgotocollegeataroundthesametime.”意為“面臨自己將要退休,同時孩子要上大學,這確實有點令人害怕?!蔽覀兛芍猅ally對支付自己女兒的學費有點害怕。B、C、D均不是作
