六、作文(1題)46.1.目前，越來越多的大學(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這些旅行者們打算去臺(tái)灣，他們計(jì)劃在那里待上兩三天。

［考點(diǎn)］定語從句

【精析】D分析句子結(jié)構(gòu)可知，句中缺少一個(gè)連接詞來引導(dǎo)非限制性定語從句，且該連接詞在句中作狀語，故排除選項(xiàng)A、B；又因先行詞為Taiwan,表示地點(diǎn)，所以排除選項(xiàng)C。故選D

2.C盡管在我們鎮(zhèn)上沒有什么娛樂項(xiàng)目，但我依然對每天晚上相同的節(jié)目感到厭煩。

［考點(diǎn)］詞語搭配

【精析】Cbetiredofsth.為固定搭配，意為對……厭倦、厭煩。bored：厭煩的，常與with搭配；ill：有病的；exhausted：筋疲力盡的，常與from/by搭配

3.C面對所有的困難，女孩向她的前男友尋求幫助。

［考點(diǎn)］詞義辨析

【精析】Cturnover:翻閱，把……翻過來；turn與from不構(gòu)成固定搭配；turnto:向……尋求幫助；turnup:露面，（尤指失去后偶然）被發(fā)現(xiàn)。根據(jù)句意可知，選C

4.C當(dāng)你填完表格后，自己留著上面的部分，另一部分寄給銀行。

［考點(diǎn)］詞義辨析

【精析】Cothers：其他的人或物，相當(dāng)于other+復(fù)數(shù)名詞；other：其他的，其后常跟復(fù)數(shù)名詞；theother：（兩者中的）另一個(gè)，常與one搭配，構(gòu)成one…theother…結(jié)構(gòu)；theothers：其余所有的人或物，相當(dāng)于therest。根據(jù)句意可知，此處指的是除了上面部分以外的另一部分，所以應(yīng)用theother修飾單數(shù)名詞part。故選C

5.BB句意：你來機(jī)場為我送行真是太體貼了。詞語搭配。seesb.off為固定搭配，意為為某人送行

6.B不管是誰對這個(gè)項(xiàng)目負(fù)責(zé)，都將受到懲罰。

［考點(diǎn)］主語從句

【精析】B分析句子結(jié)構(gòu)可知，空處引導(dǎo)的是主語從句，從句中缺少主語，所以應(yīng)用whoever引導(dǎo)主語從句，相當(dāng)于anyonewho，意為無論誰，……的任何人。whom在主語從句中充當(dāng)賓語；that在主語從句中無詞義且不充當(dāng)任何成分，只起連接作用；anyone不可引導(dǎo)從句，均可排除。故選B

7.C造成了這次事故的原因完全是個(gè)謎。

［考點(diǎn)］主語從句

【精析】C分析句子結(jié)構(gòu)可知，was前是個(gè)主語從句，從句中缺少主語，所以應(yīng)用連接代詞what引導(dǎo)從句，并在從句中作主語。which含有選擇意義；whether在從句中不作成分；why是連接副詞，在從句中作原因狀語，均不符合題意。故選C

8.D在會(huì)議上他講話速度如此之快，以至于我們幾乎沒聽懂他的話。

［考點(diǎn)］狀語從句

【精析】D分析句子結(jié)構(gòu)可知，句中包含了一個(gè)結(jié)果狀語從句。由句中的so一詞可知，空處應(yīng)用that，構(gòu)成so…that…結(jié)構(gòu)，引導(dǎo)結(jié)果狀語從句。其他三個(gè)選項(xiàng)均無此用法。故選D

9.A他又有了一項(xiàng)絕妙的發(fā)現(xiàn)，我認(rèn)為這一發(fā)現(xiàn)對科學(xué)很重要。

［考點(diǎn)］定語從句

【精析】A分析句子結(jié)構(gòu)可知，本句考查which引導(dǎo)的非限制性定語從句的用法。注意此處關(guān)系代詞which指代的是先行詞discovery，并且在從句中充當(dāng)主語。B項(xiàng)中出現(xiàn)多余主語it;C項(xiàng)缺少從句謂語動(dòng)詞；D項(xiàng)缺少關(guān)系詞

10.B我花了50美元來買他的這幅畫，但這幅畫的真正價(jià)值一定在500美元左右。

［考點(diǎn)］詞義辨析

【精析】Bfee:服務(wù)費(fèi)，報(bào)酬；value:價(jià)值；price:價(jià)格，價(jià)錢；fare:車費(fèi)，票價(jià)。根據(jù)句意可知，選B

11.C報(bào)告指出11歲的男孩和女孩中有三分之二喜歡冰淇淋。

［考點(diǎn)］數(shù)詞的用法

【精析】C表示分?jǐn)?shù)三分之二時(shí)，分子二用基數(shù)詞two,因?yàn)橐呀?jīng)大于一，所以分母應(yīng)用三的序數(shù)詞third的復(fù)數(shù)，即two-thirds,同時(shí)分?jǐn)?shù)后接名詞時(shí)要加of,所以選項(xiàng)C正確

12.D【翻譯】他沒有足夠的經(jīng)驗(yàn),而他的哥哥在修理汽車方面經(jīng)驗(yàn)豐富。［考點(diǎn)］詞義辨析Dexperience作“經(jīng)驗(yàn)”講時(shí),是不可數(shù)名詞;作“經(jīng)歷”講時(shí),是可數(shù)名詞。experienced：有經(jīng)驗(yàn)的,常與介詞in連用,構(gòu)成固定搭配beexperiencedin,意為“在……方面有經(jīng)驗(yàn)”。根據(jù)句意和搭配可知,選D。

13.D根據(jù)該規(guī)定，要求對系統(tǒng)進(jìn)行檢查以確保其處于良好狀態(tài)。

［考點(diǎn)］動(dòng)詞時(shí)態(tài)和語態(tài)

【精析】D根據(jù)句意和從句中的are可知，本句應(yīng)用一般現(xiàn)在時(shí)。又因inspections和demand之間是邏輯上的動(dòng)賓關(guān)系，所以應(yīng)用一般現(xiàn)在時(shí)的被動(dòng)語態(tài)，即謂語動(dòng)詞用am/is/are+過去分詞的形式。故選D

14.D如果不想,你不必讀那篇文章。

［考點(diǎn)］情態(tài)動(dòng)詞

【精析】Dshouldn't：不應(yīng)該，應(yīng)該不會(huì)；can't：不能,不會(huì)；mustn't：禁止,一定不能；needn't：不必,不需要，符合題意。故選D

15.D在全體團(tuán)隊(duì)成員的支持下，他們最終為公司贏得了那個(gè)大項(xiàng)目。

［考點(diǎn)］非謂語動(dòng)詞

【精析】D分析句子結(jié)構(gòu)可知,逗號前后兩部分之間沒有連詞，且逗號后是一個(gè)完整的句子，因此空處應(yīng)用非謂語動(dòng)詞形式。根據(jù)句意和句中的by可知，they與support之間是邏輯上的動(dòng)賓關(guān)系，所以應(yīng)用過去分詞形式表被動(dòng)。A項(xiàng)是不定式的被動(dòng)式，表示目的或?qū)?；B項(xiàng)是現(xiàn)在分詞的一般式，表示主動(dòng)或正在進(jìn)行；C項(xiàng)是現(xiàn)在分詞的完成式，表示主動(dòng)和已完成，均不符合題意。故選D

16.B

17.A在我看來，這是一種完全不同的情況。

［考點(diǎn)］詞義辨析

【精析】Aentirely：完全地，徹底地；merely：僅僅，只不過；briefly：短暫地，概括地；fully：充分地。根據(jù)句意可知，選A

18.C如果你正逐步遠(yuǎn)離鐘塔，你將會(huì)聽到鐘表的嘀嗒聲逐漸地消失直到聽不到。

［考點(diǎn)］定語從句

【精析】C分析句子結(jié)構(gòu)可知，空處引導(dǎo)定語從句，先行詞apoint在此指某一點(diǎn)，表示地點(diǎn)，因此應(yīng)用關(guān)系副詞where引導(dǎo)從句。故選C

19.C一些本地公司正在努力與外國公司競爭，以獲得一定的市場份額。

［考點(diǎn)］詞義辨析

【精析】Cconnect：連接；combine：組合；compete：競爭，常與介詞with搭配使用，意為與……競爭；compare：比較。根據(jù)句意可知，選C

20.C盡管這位老人眼瞎了，但他有一只靈敏的耳朵可以聽到哪怕是最小的聲音。

［考點(diǎn)］狀語從句

【精析】C分析句子結(jié)構(gòu)并結(jié)合選項(xiàng)可知，空處為as引導(dǎo)的讓步狀語從句，從句應(yīng)用倒裝結(jié)構(gòu)，即將表語或狀語等提至句首。此處應(yīng)將作表語的blind提至句首，所以選C

21.D

22.B

23.E

24.B

25.B

26.A

27.C

28.B

29.E由約翰說的第二句話That’sinthesoutheast.可知，空處應(yīng)是對地點(diǎn)的詢問，故本題應(yīng)選E。WhichpartofEnglandisthat?意為它在英國的哪一部分

30.E

31.abilitiesabilities題干的大意是：我認(rèn)為在同一個(gè)班里教授能力各異的學(xué)生是不明智的。此處應(yīng)為able的名詞形式ability，且因不同的能力，應(yīng)用其復(fù)數(shù)形式abilities

32.beshortenedbeshortened句意：通知說，午飯時(shí)間將從一個(gè)小時(shí)縮短到45分鐘。動(dòng)詞的語態(tài)。由于主語thelunchtime和動(dòng)詞shorten之間為邏輯上的動(dòng)賓關(guān)系，故此處應(yīng)用動(dòng)詞的被動(dòng)語態(tài)

33.additionaladditional題干的大意是：他完成作業(yè)之后，又找來了一些額外的練習(xí)去做。此處應(yīng)填addition的形容詞形式additional，意為分外的，額外的

34.pressurepressure題干大意是：所有的人都在重壓之下不分晝夜地工作。此處應(yīng)填由press引申出來的名詞形式pressure,指壓力,作under的賓語

35.disappointingdisappointing題意：她兒子考試沒及格的消息令她很失望，她幾乎不能相信。根據(jù)空前的was可知，空處應(yīng)使用disappoint的形容詞形式。在由disappoint轉(zhuǎn)化而來的兩個(gè)形容詞disappointing和disappointed（形容詞化的現(xiàn)在分詞和過去分詞）中,其主語若為人，則用disappointed，意為某人感到失望的；若為物，則用disappointing,意為某事/某物令人失望的。在本句中，主語為news,應(yīng)使用disappointing

36.B
