六、作文(1題)39.1.目前，越來(lái)越多的大學(xué)生做兼職。2.大學(xué)生做兼職的利弊。3.你的看法。

參考答案

1.D湯姆的臥室亂成一團(tuán)，因?yàn)榈教幎际菚图垺?/p>

［考點(diǎn)］固定搭配

【精析】Dinamess是固定搭配，意為亂成一團(tuán)。其他名詞無(wú)此用法

2.D解析：A項(xiàng)的"knownas"意思為“作為……而聞名”；B項(xiàng)“knownto”意思為“對(duì)……聞名”；C項(xiàng)搭配不正確；D項(xiàng)的“knownfor”意思為“因?yàn)椤劽?。答案為D，全句意思為“北京因?yàn)槠淦恋娘L(fēng)景和長(zhǎng)城而聞名于世”。

3.B句意：這樣的辦公設(shè)備無(wú)疑將會(huì)對(duì)我的工作方式產(chǎn)生影響?？疾楣潭ù钆?。makesense:有意義、講得通；makeadifferencetosb./sth．：對(duì)某人（某物）產(chǎn)生影響；haveaneffectonsth．：對(duì)……有影響；選項(xiàng)D不能與to搭配。根據(jù)句子意思應(yīng)該選擇B

4.D三天后，蓋瑞表現(xiàn)得就好像什么都沒(méi)發(fā)生過(guò)一樣。

［考點(diǎn)］虛擬語(yǔ)氣

【精析】D根據(jù)謂語(yǔ)動(dòng)詞和句意可知，此處是asthough引導(dǎo)的方式狀語(yǔ)從句，表示對(duì)過(guò)去發(fā)生事情的假設(shè)，從句的謂語(yǔ)動(dòng)詞要用had+過(guò)去分詞的形式。故選D

5.B經(jīng)過(guò)再三考慮，我們決定不賣房子了。

［考點(diǎn)］詞語(yǔ)搭配

【精析】Bonsecondthoughts為固定搭配，意為經(jīng)重新考慮后，再三考慮，一般用于表示突然改變主意。故選B

6.A直到那天我才意識(shí)到，有禮貌在工作面試中的重要性。

［考點(diǎn)］倒裝句

【精析】A表示否定的詞not,never,seldom,little等和短語(yǔ)notuntil，notonly,innocase,innotime等在句首時(shí)句子要部分倒裝。notuntil后面用一般過(guò)去時(shí)，故把助動(dòng)詞did提前即可

7.B湯姆不會(huì)講漢語(yǔ)，但是彼得能講漢語(yǔ)。

［考點(diǎn)］動(dòng)詞時(shí)態(tài)

【精析】B情態(tài)動(dòng)詞can't表示對(duì)現(xiàn)在能力的否定，所以后面的分句也要用一般現(xiàn)在時(shí)。主語(yǔ)Peter為第三人稱單數(shù)，因此助動(dòng)詞應(yīng)用does。故選B

8.A由于公司在拓展業(yè)務(wù)，擴(kuò)大工廠很有必要。

［考點(diǎn)］詞義辨析

【精析】Aextend：擴(kuò)大，擴(kuò)展；increase：增加，提高；rise：（數(shù)字、數(shù)量、價(jià)值等）增加，增長(zhǎng)；grow：成長(zhǎng)，種植。根據(jù)句意可知，選A

9.B學(xué)院正打算開設(shè)更多英語(yǔ)課程來(lái)滿足英語(yǔ)初學(xué)者的需要。

［考點(diǎn)］詞語(yǔ)搭配

【精析】Bmeettheneedsof…為固定搭配，意為滿足……的需要

10.C災(zāi)區(qū)的首要任務(wù)是預(yù)防傳染病的爆發(fā)，以及提供水和食物。

［考點(diǎn)］詞義辨析

【精析】Ccasual：漫不經(jīng)心的，隨便的；attractive：有吸引力的；primary：首要的，主要的，基本的；simple：簡(jiǎn)單的。根據(jù)句意可知，選C

11.DD句意：我無(wú)法說(shuō)出這對(duì)雙胞胎之間的細(xì)微差別。詞義辨析題。slender：苗條的，修長(zhǎng)的；single：?jiǎn)我坏?；simple：簡(jiǎn)單的；slight：輕微的，少量的。故選D

12.A農(nóng)民們被允許在自己的園子里種菜，并將蔬菜拿到市場(chǎng)上去賣。

［考點(diǎn)］詞語(yǔ)搭配

【精析】Aonthemarket為固定搭配，意為上市，出售。故選A

13.B——好豐盛的晚餐！

——謝謝，很高興你能喜歡它。

［考點(diǎn)］情景交際

【精析】B當(dāng)對(duì)方稱贊好豐盛的晚餐！時(shí)，回答者除了表達(dá)感謝外，接下來(lái)應(yīng)該會(huì)表達(dá)很高興你能喜歡它。故B項(xiàng)符合題意

14.A十九世紀(jì)的著名作家查爾斯·狄更斯寫了很多暢銷小說(shuō)，其中《霧都孤兒》就是一個(gè)很好的例子。

［考點(diǎn)］定語(yǔ)從句

【精析】A分析句子結(jié)構(gòu)可知，逗號(hào)后面是一個(gè)非限制性定語(yǔ)從句。關(guān)系詞指代的是先行詞novels，OliverTwist與先行詞之間為所屬關(guān)系，所以應(yīng)用介詞of，空處應(yīng)用ofwhich。故選A

15.A眾所周知，在國(guó)際交流中英語(yǔ)是最為廣泛使用的語(yǔ)言之一。

［考點(diǎn)］定語(yǔ)從句

【精析】A分析句子結(jié)構(gòu)可知，本句為非限制性定語(yǔ)從句。as和which均可以引導(dǎo)非限制性定語(yǔ)從句，指代整個(gè)句子。as引導(dǎo)的非限制性定語(yǔ)從句可以放在主句之前，或者主句之后，甚至可以切割主句；which引導(dǎo)的非限制性定語(yǔ)從句只能放在主句之后。另外as引導(dǎo)的非限制性定語(yǔ)從句中有很多可以當(dāng)作固定搭配，如asisknowntoall,asisoftenthecase,asismentionedabove,asoftenhappens等。故選A

16.C［翻譯］這是她第三次競(jìng)賽獲勝了，這讓我們所有人都很吃驚。

［考點(diǎn)］定語(yǔ)從句

引導(dǎo)，且常用逗號(hào)將其與先行詞分開，先行詞可以是一個(gè)單詞，也可以指代前面的句子。此題中which指代前面的整個(gè)句子

17.D正如以前所指出的那樣，英語(yǔ)語(yǔ)法不是一套死規(guī)則。

［考點(diǎn)］定語(yǔ)從句

【精析】D分析句子結(jié)構(gòu)可知，這是一個(gè)非限制性定語(yǔ)從句。選項(xiàng)A、B、C均不能引導(dǎo)非限制性定語(yǔ)從句；as引導(dǎo)非限制性定語(yǔ)從句時(shí)，可位于主句之前，也可位于主句之后，甚至可以切割整個(gè)主句。另外，as有正如，正像的意思。故選D

18.D請(qǐng)把電視的音量調(diào)小一點(diǎn)兒，好嗎？孩子們正在做作業(yè)。

［考點(diǎn)］詞義辨析

【精析】Dturnon：打開；turnoff：關(guān)掉，關(guān)閉；turnup：開大，調(diào)高（音量），出現(xiàn)；turndown：關(guān)小，調(diào)低，拒絕。根據(jù)句意可知，選D。注意：如果句子中沒(méi)有alittle,B項(xiàng)也符合題意

19.AA句意：很高興告訴您，您定購(gòu)的傳真機(jī)現(xiàn)在有貨了。詞義辨析題。available：可得到的，有售的；convenient:方便的；wonderful:極好的；important:重要的。根據(jù)句意可知,A項(xiàng)正確

20.A當(dāng)我們到達(dá)機(jī)場(chǎng)的時(shí)候，我們被告知我們所乘坐的航班已經(jīng)取消了。

［考點(diǎn)］動(dòng)詞時(shí)態(tài)

【精析】Acancel這一動(dòng)作發(fā)生在主句謂語(yǔ)動(dòng)詞tell之前，所以應(yīng)用過(guò)去完成時(shí)，表示過(guò)去的過(guò)去發(fā)生的動(dòng)作。故選A

21.FK根據(jù)空后的名詞短語(yǔ)15years可知，空處應(yīng)填介詞。符合要求的選項(xiàng)有C、K。句意：15年來(lái)，來(lái)自倫敦大學(xué)學(xué)院的專家們一直在調(diào)查超過(guò)6,700名英國(guó)人的生活方式。故選K。

22.HH分析句子結(jié)構(gòu)可知，空處應(yīng)填引導(dǎo)詞，引導(dǎo)一個(gè)定語(yǔ)從句，修飾指人的先行詞friends。符合要求的選項(xiàng)只有H。句意：學(xué)生在上大學(xué)時(shí)可以學(xué)習(xí)并交到將持續(xù)一生的朋友。故選H。

23.JA.studied（v.學(xué)習(xí)，研究）B.continuing（v.繼續(xù)，持續(xù)）C.by（prep.通過(guò)）D.who（pron.引導(dǎo)定語(yǔ)從句）E.whose（pron.引導(dǎo)定語(yǔ)從句）F.improve（v.改進(jìn)，改善）G.truth（n.事實(shí)，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(shí)間）L.less（adv.更少，較少）J分析句子結(jié)構(gòu)可知，空后的who引導(dǎo)一個(gè)定語(yǔ)從句，空處為其先行詞，所以空處應(yīng)填指人的名詞或代詞。符合要求的選項(xiàng)只有J。those在此處指代上文中的people，此處表達(dá)的是“不去（音樂(lè)會(huì)、演出和博物館）的那些人”。故選J。

24.absenceabsence題意：警方因缺乏有關(guān)這起犯罪的信息而被耽擱。根空前的the和空后的of可知，空處應(yīng)填absent的名詞形式absence（缺乏，沒(méi)有）

25.improvementimprovement句意：你的工作計(jì)劃現(xiàn)在好多了，但仍有提高的空間。詞性轉(zhuǎn)換。由介詞for可知，此處應(yīng)用動(dòng)詞improve的名詞形式improvement來(lái)作其賓語(yǔ)，意為改進(jìn)，提高

26.povertypoverty題干大意是：由于缺乏想象力，他晚年創(chuàng)作的故事并不有趣。根據(jù)his可知，此處應(yīng)填poor的名詞形式poverty，指缺乏

27.societysociety題干大意是：在我們社會(huì)中，勞動(dòng)人民是國(guó)家的主人。society指社會(huì)，是social引申出的名詞形式

28.economiceconomic題干的大意是：全世界都認(rèn)為我國(guó)迅速的經(jīng)濟(jì)發(fā)展是個(gè)奇跡。此處需要economy的形容詞形式economic，修飾名詞development
