六、作文題(1題)54.Directions:Forthispart,youarerequiredtowriteacompositionofabout100words.Yourwritingshouldbebasedonthetitleandoutlinegivenbelow.

ShouldCustomersBuyCut-priceProducts?

1.現在許多人都喜歡買打折商品；

2.而另一些人認為越是打折的商品越不能買；

3.你的看法

參考答案

1.C在過去的五年里，中國在其文化價值上有了很大的改變。

［考點］動詞的時態

【精析】C由句中的overthepastfiveyears可以判斷時態為現在完成時

2.D交友的最佳方式是，與他人展開對話，找出你們的共同興趣，并以此為出發點。

［考點］詞義辨析

【精析】Dleadto:導致，通向；laydown:放下；keepon:繼續；findout:找出，查明。根據句意可知，選D

3.D晚餐馬上就好。咱們去洗手吧。

［考點］詞組辨析

【精析】Datall:完全；atleast:至少；justnow:剛才，剛剛；rightaway:立即，馬上。根據句意，選D

4.A來吧，現實點吧；生活已不是你那個年代的樣子了。

［考點］名詞性從句

【精析】A分析句子結構可知，空處缺少一個引導表語從句的連接詞，同時該詞在從句中還作was的表語，四個選項中只有what（什么）有此用法

5.D句意：一個人要想創業，必須要擁有一定的資金。詞義辨析題。currency：通貨，貨幣；income：收入；wealth：財產，財富；capital：資本，資金，本錢。根據句意應選D

6.C句意：人類砍伐森林為了種莊稼，或者用樹木作燃料。本題考查的是冠詞的用法。句子中森林（forests）用的是復數，表達的是泛指的意思，不能加冠詞；第二空后的wood是指前面所提到的森林里砍伐來的木材，此處應為特指。所以選擇答案C

7.A當圣誕節越來越近時，孩子們變得越來越興奮。

［考點］詞義辨析

【精析】Adraw:移動，行進，臨近，與near連用構成drawnear（臨近，靠近）。join:連接，會合；take:拿，取；operate:運轉，操作。根據句意可知，選A

8.D我記得付過我薪水了，但我不記得具體的金額了。

［考點］非謂語動詞

【精析】Dremembertodosth.意為記得做某事，動作未發生；rememberdoingsth.意為記得做過某事，動作已經發生。pay和I為邏輯上的動賓關系，所以應用被動語態。根據句意可知，選D

9.C［翻譯］這種新型藥物用于人類還將再花費五到十年的時間。

［考點］詞義辨析

【精析】C四個選項均有花費的意思。spend的主語必須是人，故排除；waste多有浪費之意，不符合句意，也排除；cost的主語可以是人也可以是物，常見用法是（1）sth.costs（sb.）+金錢；（2）（doing）sth.costs（sb.）+時間；而take則多用于句型Ittakessb.+時間+todosth.。故本題應選take

10.A住在這些公寓里的人有免費使用那個游泳池的權利。

［考點］詞義辨析

【精析】Aaccess:接近的機會，使用權；excess:過量，過多；excursion:遠足，短途旅行；recreation:消遣，娛樂。根據句意可知，選A

11.AA句意：盡管生病了,他還是堅持來上班。本題考查當as引導讓步狀語從句時要主謂倒裝,故選A。需要注意的是：though,as,that在引導讓步狀語從句時,均可主謂倒裝,其中though用于倒裝多見于口語中,它也可放在句首引導而不倒裝,as和that則必須倒裝,但although引導讓步狀語從句時不可倒裝。例如：Richasheis,heisthrifty.Childthatheis,hehasreadalot.（表語為單數可數名詞,原不定冠詞需略去）Hardthoughheworked,hecouldscarcelyearnenoughtomakebothendsmeet.由以上解析不難看出,不嚴格地說,其實本題選項B.though亦可作為答案，但作為單選題A是最佳的

12.C

13.B科學家們稱：這種藥物能用在人身上之前可能還需要五六年。

［考點］詞義辨析

【精析】Bsince：自從，因為，由于；before：在……之前；after：在……之后；when：當……時。根據句意可知，選B

14.B如果你只在這個城市待幾天，我們可以給你一張臨時的借書證，以便你可以查看市圖書館的書籍。

［考點］詞義辨析

【精析】Bterminal：晚期的，致命的；temporary：臨時的，暫時的；regular：有規律的，定期的；permanent：永久的。根據句意可知，選B

15.AA句意：什么也逃不開警察的關注。詞義辨析題。escape意為逃離，未被注意到，此時為及物動詞；flee意為（尤指害怕有危險而）逃跑；ignore意為不理睬，忽視；neglect意為疏忽，忽視。根據句意，答案為A

16.D他沒有足夠的經驗,而他的哥哥在修理汽車方面經驗豐富。

［考點］詞義辨析

【精析】Dexperience作經驗講時,是不可數名詞;作經歷講時,是可數名詞。experienced：有經驗的,常與介詞in連用,構成固定搭配beexperiencedin,意為在……方面有經驗的。根據句意和搭配可知,選D

17.A這個男孩很聰明，但在學習上相當懶惰。

［考點］詞義辨析

【精析】A根據句意可知，空前的intelligent和空后的lazy形成轉折關系，應用but連接，故可排除選項B、D；rather和quite都可表示很，非常，相當，但是quite一般用于修飾表示褒義的形容詞或副詞，而rather一般修飾表示貶義的形容詞或副詞。故選A

18.B不管別人說什么，做你認為對的事情。

［考點］狀語從句

【精析】B分析句子結構可知，本句為狀語從句，連接詞在從句中作賓語。however:不管怎樣，無論如何，表示程度和方式；whatever:無論什么，可在從句中作主語，賓語和表語；whichever:無論哪個，一般有選擇范圍；ifonly:但愿，要是……就好了，句中常用虛擬語氣。故選B

19.A他的父母上周去世了，所以這個孩子沒有人照顧。

［考點］非謂語動詞

【精析】A分析句子結構可知，逗號后面的句子結構完整，逗號前后兩部分沒有連接詞連接，所以逗號前應是獨立主格結構，所以空處應用非謂語動詞。die和其邏輯主語Hisparents之間是主謂關系，而且die所表示的動作發生在謂語動詞所表示的動作之前，所以此處應用現在分詞的完成式。故選A

20.A句意：——喂，約翰，音樂會怎么樣？——太精彩了！瑪麗和大衛活靈活現的表演給我們留下了深刻的印象。單詞辨析題。flexibly：靈活地；specifically：特別地、明確地、具體地；faithfully：忠實地、如實地；nervously：焦急地、提心吊膽地。根據句意可知應該選擇A

21.FK根據空后的名詞短語15years可知，空處應填介詞。符合要求的選項有C、K。句意：15年來，來自倫敦大學學院的專家們一直在調查超過6,700名英國人的生活方式。故選K。

22.JA.studied（v.學習，研究）B.continuing（v.繼續，持續）C.by（prep.通過）D.who（pron.引導定語從句）E.whose（pron.引導定語從句）F.improve（v.改進，改善）G.truth（n.事實，真相）H.ignored（v.忽視，不予理睬）I.recently（adv.最近，不久前）J.those（pron.那些）K.for（prep.表示一段時間）L.less（adv.更少，較少）J分析句子結構可知，空后的who引導一個定語從句，空處為其先行詞，所以空處應填指人的名詞或代詞。符合要求的選項只有J。those在此處指代上文中的people，此處表達的是“不去（音樂會、演出和博物館）的那些人”。故選J。

23.HH分析句子結構可知，空處應填引導詞，引導一個定語從句，修飾指人的先行詞friends。符合要求的選項只有H。句意：學生在上大學時可以學習并交到將持續一生的朋友。故選H。

37.美國被認為是一個體育強國

38.Smokingshouldbetotallyprohibitedinallthepublicplaces

39.他不來信，我也不會給他寫信

40.BB分析題干可知，句子前后表示讓步關系，譯文中可以用despite,inspiteof,though,although等表示。A項漏譯了盡管，句子不完整，故排除；C項though后應該接的是從句，故可排除；D項譯成了這個16歲的女孩的父母強烈反對她自己出國旅行的決定，與題干表達的意思不符。故選B

41.Thereisnodenyingthatairpollutionisanextremelyseriousproblem

42.Myfathervalueshonestybeyondallthings

43.Weshouldhelpourfriendswithouthesitationwhentheygetintotrouble

44.A［考點］推理判斷題

【精析】A根據表格結尾部分Phone:27922234Website:/lnec可知，表格末尾介紹了中心的電話和網址。由此可推知，要想了解獅子自然教育中心更多的信息，可以撥打電話或瀏覽官網信息。故選A

45.D［考點］事實細節題

【精析】D根據第二段第二、三句Indensetraffic…saystrayer.可知，開車打電話的司機對緊急情況的反應速度比不打電話的司機要慢２０％，撞上前方車輛的概率要大一倍，獲取的視覺信息也要少于５０％。因此選項Ａ、Ｂ、Ｃ均正確。文中并未提到這１１０位司機不樂意參加實驗。故選Ｄ

46.B［考點］詞語理解題

【精析】B根據第三段第三句Atleast13studieshavetriedto…andtheresultshavepointedineverydirection.可知，降低食鹽攝入量的益處并不確定。由此可知，murky意為含糊的，不確定的。significant:重大的,重要的,有意義的；unclear:不清楚的,不確定的；obvious:明顯的,顯著的；exaggerated:夸張的，言過其實的。故選B

47.B［考點］推理判斷題

根據第一段最后五句Sothinkbeforeyoustarteating.Itmaylookgood.Itmaytastegood.Fine!Buthowmuchgoodisitreallydoingyou?可知，吃東西前要三思，食物可能色香味俱全，但是它對你真正的好處有多少?由此可推知，在吃東西前，我們要思考是否真正需要它。故選B

48
