參考答案

1.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)來描述，而我卻認(rèn)為它是這個(gè)計(jì)劃中最重要的部分。

2.A解析：while意為“雖然”；as意為“因?yàn)椤?；if意為“如果”；since意為“因?yàn)椤?。根?jù)題意選A。

3.C

4.B

5.D解析：本題考查動(dòng)詞搭配。doone'shomework“做作業(yè)”；makemistakes“犯錯(cuò)誤”。句意為：做作業(yè)，還要保證別犯錯(cuò)誤。

6.D

7.D

8.Ainparticular是固定搭配，意為“特別地”。

9.A

10.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。

11.B考查反義疑問句。原句應(yīng)是：youwouldthinkhehadhaveforgotten…反義疑問句的規(guī)則是陳述部分是肯定式，疑問部分應(yīng)是否定式。Wouldthink表示推測(cè)，疑問部分也應(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?

12.C

13.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。

14.B解析：takemeasures意思為“采取措施”，本句應(yīng)用被動(dòng)語態(tài)。

15.B

16.D

17.C

18.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。

19.A

20.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。

21.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。

22.C

23.C

24.B

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

26.D解析：which修飾非限定性定語從句，指代前邊一句話。本題涉及句法知識(shí)——簡單句、并列句和復(fù)合句。例如：Hehastwodaughters.Theyaredoctors.(簡單句)Hehastwodaughtersandtheyaredoctors.(并列句)Hehastwodaughters,whoaredoctors．(復(fù)合句)

27.B

28.D

29.B解析：theeducationsystem是主語，謂語動(dòng)詞應(yīng)用單數(shù)；thedesiredresults意為“期望的結(jié)果”。

30.B解析：表示否定的副詞前置于句首，句子需要不完全倒裝，即助動(dòng)詞提前。其余選項(xiàng)均可排除。除Notuntil外還有never，seldom，rarely，seldom，no，little，hardly，innotime等否定副詞或結(jié)構(gòu)放在句首時(shí)，句子需要部分倒裝。

31.A本題考查祈使句型：

【應(yīng)試指導(dǎo)】句意：Mary，到這里來，其余的人待在原處。根據(jù)句子的結(jié)構(gòu)可判斷出這是個(gè)祈使句。所以要用動(dòng)詞原形開頭。Mary在句中不是

主語，而是“呼語”。

32.C解析：副詞so置于句首，句子應(yīng)該用倒裝語序，某人受傷用sb.beinjured來表示，故答案為C。

33.B

34.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：“你說過電視是有教育意義的?！彼訢項(xiàng)正確。

35.C

36.B

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

38.A解析：本題考虛擬語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，謂語動(dòng)詞應(yīng)用“should+認(rèn)”，should可以省去，再結(jié)合語態(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辦公室。

39.D

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)代我向你的妻子問好。在時(shí)間狀語從句中用一般現(xiàn)在時(shí)代替一般將來時(shí)。

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

42.A解析：根據(jù)上文提到“findone”，故下文中也應(yīng)填one，表示泛指。

43.A

44.C

45.C解析：much用在句中修飾比較級(jí)better。

46.Dapplyto應(yīng)用；applyfor申請(qǐng)

47.Bsetout意為“出發(fā)，動(dòng)身”。

48.A

49.C解析：本題考查倒裝虛擬語氣用法。本句是表示與將來事實(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。

50.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。

51.B

52.C

53.D

54.B

55.后面是解釋原因?yàn)槭裁聪矚g，有比較的含義，所以，這里也應(yīng)是表示對(duì)比的。選項(xiàng)A是正確的。

56.B

57.D

58.A

59.C

60.E

61.A解析：but表示轉(zhuǎn)折。從前句“No”推出后句應(yīng)填“Yes”。

62.A解析：詞義辨析。根據(jù)上題分析的句意，此處為采取行動(dòng)，所以選擇done。

63.B解析：keepdoingsth，表示“持續(xù)做某事”。

64.B

65.A解析：詞語搭配題。和channel搭配的只有through，其余三詞都不能搭配。

66.A解析：instead是副詞，表示“相反”，可做獨(dú)立成分。insteadof為介詞短語，表示“作為某物/人的替換”，后須接名詞或名詞性結(jié)構(gòu)。

67.C解析：toone'ssurprise“讓某人驚奇的是”，固定搭配。

68.D解析：representingthenewstates“代表著兩個(gè)新州”，該結(jié)構(gòu)是現(xiàn)在分詞短語，修飾stars，因?yàn)閟tars和represent之間是主動(dòng)關(guān)系，所以用現(xiàn)在分詞來表示。

69.A解析：本空格前后是兩個(gè)分句，因此可排除C項(xiàng)suchas和D項(xiàng)possibly。B項(xiàng)i．e．“那就是”放入句中意思不通，因此應(yīng)選A項(xiàng)as，句意為“就像高爾夫球和足球有規(guī)則一樣”。

70.C

71.我很難趕上班里的其他同學(xué)。

72.外國學(xué)生在美國讀書期間不能打工因此他們必須向?qū)W校表明有足夠的錢來支付學(xué)費(fèi)和生活費(fèi)．外國學(xué)生在美國讀書期間不能打工，因此他們必須向?qū)W校表明有足夠的錢來支付學(xué)費(fèi)和生活費(fèi)．
