參考答案

1.Ainparticular是固定搭配，意為“特別地”。

2.B

3.B解析：本題考查固定搭配。havetrouble(in)doingsth.“做某事有困難”。句意為：有時(shí)孩子們?cè)诜智骞适潞同F(xiàn)實(shí)方面會(huì)有困難，相信故事中的事確實(shí)存在。

4.A解析：本題考虛擬語(yǔ)氣在名詞性從句中的用法。在“ask(advise，desire，ordersuggest，require，etc。)+the廣引導(dǎo)的從句中，謂語(yǔ)動(dòng)詞應(yīng)用“should+認(rèn)”，should可以省去，再結(jié)合語(yǔ)態(tài)，故A項(xiàng)正確。本句大意為：他們要求所有的必要文件都必須在月底之前交到校長(zhǎng)辦公室。

5.C解析：副詞so置于句首，句子應(yīng)該用倒裝語(yǔ)序，某人受傷用sb.beinjured來(lái)表示，故答案為C。

6.D

7.A解析：句意：她昏倒了。給她臉上澆些水，或許她會(huì)醒過(guò)來(lái)。本題考查詞組辨析。comeround：過(guò)訪，繞道而來(lái)，蘇醒過(guò)來(lái)；comeback：回來(lái)，恢復(fù)；comeagain：再說(shuō)一遍，重復(fù)一遍；comeout：出來(lái)，傳出。

8.Dapplyto應(yīng)用；applyfor申請(qǐng)

9.B解析：本題考查固定搭配的用法。當(dāng)否定詞位于句前時(shí)，得出結(jié)論應(yīng)用reach/achievein/arriveatconclusion，故選B。

10.C

11.A本句考查兩個(gè)并列句之間的連接的詞。題干的意思是：“氣球能夠浮在空氣中正如船能夠浮在海面上一樣?！痹谒膫€(gè)選項(xiàng)中，只有A項(xiàng)的justas有“正如，猶如”的意思。故選A。

12.B解析：encourage：鼓勵(lì)、鼓舞；discourage：使泄氣；prevent：阻止；ask：要求。根據(jù)句意只有選B。

13.A

14.D

15.A

16.C

17.C解析：本題考查倒裝虛擬語(yǔ)氣用法。本句是表示與將來(lái)事實(shí)相反，所以從句用wereto形式。句意為：如果他今天出發(fā)的話，他就會(huì)在星期五以前到達(dá)那里。

18.D

19.B

20.Bsetout意為“出發(fā)，動(dòng)身”。

21.C解析：本題考查詞義的辨別。rise出現(xiàn)，put放下，raise提起，arise升高。

22.B解析：本題考查動(dòng)詞固定搭配的用法。deprive后常接介詞of，表示剝奪什么。

23.C

24.D解析：本題測(cè)試形容詞辨析。四個(gè)選項(xiàng)的意思分別是“普通的”，“清楚的”，“正義的”，“僅僅的”。根據(jù)句意，D項(xiàng)正確。本句大意為：他僅僅把它作為一個(gè)細(xì)節(jié)來(lái)描述，而我卻認(rèn)為它是這個(gè)計(jì)劃中最重要的部分。

25.B考查反義疑問(wèn)句。原句應(yīng)是：youwouldthinkhehadhaveforgotten…反義疑問(wèn)句的規(guī)則是陳述部分是肯定式，疑問(wèn)部分應(yīng)是否定式。Wouldthink表示推測(cè)，疑問(wèn)部分也應(yīng)選擇would。選項(xiàng)B是正確的?！揪渥哟笠狻磕汶y道還認(rèn)為他已經(jīng)忘掉了，是嗎?

26.A解析：此題考查反意疑問(wèn)句的用法。主句為祈使句，因此其反意疑問(wèn)句用willyou。

27.A

28.B

29.D

30.D

31.A

32.B

33.B

34.C

35.D

36.C

37.C

38.D解析：從句中的問(wèn)句主謂不倒裝。從句的時(shí)態(tài)隨主句。我想知道那輛車的價(jià)格。

39.C解析：notonly…butalso連接主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞根據(jù)就近原則由butalso后的成分來(lái)決定。TomandMary是兩個(gè)人，所以動(dòng)詞用復(fù)數(shù)形式。

40.D本題考查時(shí)態(tài)。

【應(yīng)試指導(dǎo)】句意：當(dāng)你寫信回家的時(shí)候，請(qǐng)代我向你的妻子問(wèn)好。在時(shí)間狀語(yǔ)從句中用一般現(xiàn)在時(shí)代替一般將來(lái)時(shí)。

41.B解析：此處是對(duì)將來(lái)情況的假設(shè)。虛擬條件句的謂語(yǔ)部分為should，had或were時(shí)，可把if省去，而把should，had或were放在從句的主語(yǔ)之前，構(gòu)成主謂部分倒裝。

42.A【句子大意】新打字機(jī)的價(jià)格是二手貨的三倍。

43.B解析：takemeasures意思為“采取措施”，本句應(yīng)用被動(dòng)語(yǔ)態(tài)。

44.D

45.A解析：favor：幫助，一般用domeafavor；good：好處；help不與do搭配：kindness：善良。故選A。

46.A解析：shape意為“(女人的)姿態(tài)，身段”；form意為“形狀，形態(tài)”；appearance意為“外表，樣子”；body意為“身體”。由題意知應(yīng)選A。

47.D解析：上句責(zé)備瑪麗應(yīng)該做作業(yè)而不是坐到那兒看電視，下句是瑪麗對(duì)媽媽責(zé)備的一種辯解：“你說(shuō)過(guò)電視是有教育意義的。”所以D項(xiàng)正確。

48.A

49.C解析：句子的前半部分是主語(yǔ)從句，主語(yǔ)從句中的謂語(yǔ)動(dòng)詞時(shí)態(tài)應(yīng)根據(jù)句意而定。

50.A解析：反問(wèn)疑問(wèn)句的陳述部分是肯定式時(shí)，疑問(wèn)部分用否定式。以letme或letus起始的反問(wèn)疑問(wèn)句，疑問(wèn)部分用willyou或won'tyou，所以選項(xiàng)A是正確的。

51.B

52.G

53.【提示】本題立足于日常表達(dá)。平日里，人們可用不同的說(shuō)法表達(dá)相同的意思，因此此題比較靈活，答案不唯一，符合題意和口語(yǔ)表達(dá)方式即可。1.【答案】Wehaven’tseeneachotherforayear【解題指要】根據(jù)中文提示得知兩人已有一年未見(jiàn)，因此填入Wehaven’tseeneachotherforayear。2.【答案】Icameherethreedaysago【解題指要】根據(jù)中文提示，她說(shuō)自己三天前才到這個(gè)地方，因此填入Icameherethreedaysago。3.【答案】Totellyouthetruth【解題指要】根據(jù)中文提示“說(shuō)實(shí)話”，此空填入Totellyouthetruth。4.【答案】Wouldyoulikesomecoffee【解題指要】根據(jù)中文提示，他想邀請(qǐng)她一起喝咖啡，因此此空填入Wouldyoulikesomecoffee。5.【答案】I’llstayhereforamonth【解題指要】根據(jù)中文提示得知他要在這里待一個(gè)月。因此該空填入l’llstayhereforamontho【參考譯文】Bill：請(qǐng)進(jìn)。Alice：謝謝。Bill：我們有一年不見(jiàn)了吧，你最近怎么樣?Alice：嗯，還不錯(cuò)。你呢?Bill：我也挺好的。Alice：我三天前剛到這里，就過(guò)來(lái)看看你。Bill：你真好。說(shuō)實(shí)在話，我真地很想念你。Alice：我也是。Bill：去喝杯咖啡怎么樣?Alice：不了，我四點(diǎn)和別人還有些事要談。我得走了。Bill：你現(xiàn)在就得走嗎?Alice：我在這里要待一個(gè)月呢。我會(huì)再來(lái)看你的。

67.D解析：本句的上半句有“donot兩詞，根據(jù)上下文，這里要選D。

68.A解析：老師說(shuō)服家長(zhǎng)看孩子的表現(xiàn)，其他選項(xiàng)不符合邏輯。

69.C本題考查動(dòng)詞的含義。該句要表達(dá)的意思是：生活中“行為(acring)”過(guò)于保守就會(huì)落伍，就像開(kāi)車太慢也會(huì)“阻止、中斷”(interrupting)別人的行程一樣。因此本題選擇C。
