16.accordingaccording解析：accordingto意為“根據(jù)”，為固定短語，本句句意為“根據(jù)對…的嚴(yán)格調(diào)查，…?！?/p>

17.amongamong解析：此句意為“后一種觀點得到了許多支持者，尤其…教育家?！憋@然，空處應(yīng)填“在…中”，介詞among即有此意。

18.forfor解析：解析見上題。desire后面用介詞for。故答案為for，表示“…的欲望”。

19.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丝仗帒?yīng)填“盡管，即使”，即eventhough。

20.productionproduction解析：從前一句話“Themanufacturersgobeyondonlytellingconsumersabouttheirproducts.”可以看出，一方面廣告要介紹自己的產(chǎn)品，而第二個目的就是賣掉自己的產(chǎn)品。所以這里作者想要表達(dá)的意思是“廣告要使得顧客有一種購買的欲望去購買自己的產(chǎn)品?！惫蚀鸢笧閜roduction。

21.ofof解析：beofthesame…意為“是一樣…”，此句意為“…在正確的指導(dǎo)下，他們能繼續(xù)學(xué)習(xí)，繼續(xù)通過干許多一樣復(fù)雜的工作而獲得多樣性?！?/p>

22.onon解析：“…的決定”英語表達(dá)為“decisiononsth．”這里介詞需要用on。故答案為on。

23.threatenthreaten解析：由33題解析可以知道此空一定為“威脅”之意。

24.displaydisplay解析：這里要回應(yīng)本段第一句話中的“displayed”。在出口結(jié)算處展示的這些小商品無疑是一種誘惑。這里需要用名詞形式。故答案為display。

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

26.C解析：由C中的howitworks中的第一條“Thiswasoriginallydevelopedinordertoprovideelectricityforsatellites…．．”可知答案為C。

27.D解析：由文章最后一段中的“Thepositivesideofitistherearebetterproducts--they’recheaperandmoreflexible．”可知。

28.D解析：第四段提到基因療法遭受的一起挫折——一個病人因接受基因療法而死亡；接著講專家擔(dān)心運動員利用基因在比賽中作弊會進(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。

29.AA解析：由上下兩段可知，只有A放在此處可以使上下文銜接，意思順暢。

30.C解析：由文章第二段可知C不對，而A、B、D文中均提到了。

31.D解析：由D中Smithadds，“Investment-wise，King’sCrossisagoodbet．Thereisabigrentalmarkethereandpriceswillgoup．Therearestillcheaperpropertiesavailable，onetotwobedroomflatsinVictorianconversions，orex—councilproperties．Butpeopleareholdingontothemfordearfifeinthehopetheywillgoupinvalue．Ifyoufindone，itisworthinvestingin．”可以看出在King’sCross投資將會物有所值。所以此處答案為D。

32.A解析：由A中的第一段“Washington，thecapitaloftheUnitedStates，isinWashingtonD.C.”可知答案為A。

33.A解析：由短文最后一段最后一句可知A不對。

34.D解析：由短文最后一段中的“Butnewmaterialshavenoimpactuntiltheyaremadeintoprod
