參考答案

1.D

2.D

3.B

4.A本句考查兩個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。”在四個選項中，只有A項的justas有“正如，猶如”的意思。故選A。

5.B

6.B解析：本題考查固定搭配。havetrouble(in)doingsth.“做某事有困難”。句意為：有時孩子們在分清故事和現(xiàn)實方面會有困難，相信故事中的事確實存在。

7.C

8.B

9.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”。由題意知應選A。

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

11.C

12.A

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

14.A本題考查祈使句型：

【應試指導】句意：Mary，到這里來，其余的人待在原處。根據(jù)句子的結構可判斷出這是個祈使句。所以要用動詞原形開頭。Mary在句中不是

主語，而是“呼語”。

15.D

16.A解析：句意：她昏倒了。給她臉上澆些水，或許她會醒過來。本題考查詞組辨析。comeround：過訪，繞道而來，蘇醒過來；comeback：回來，恢復；comeagain：再說一遍，重復一遍；comeout：出來，傳出。

17.D

18.Dapplyto應用；applyfor申請

19.D解析：本題測試形容詞辨析。四個選項的意思分別是“普通的”，“清楚的”，“正義的”，“僅僅的”。根據(jù)句意，D項正確。本句大意為：他僅僅把它作為一個細節(jié)來描述，而我卻認為它是這個計劃中最重要的部分。

20.B解析：takemeasures意思為“采取措施”，本句應用被動語態(tài)。

21.Ainparticular是固定搭配，意為“特別地”。

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

23.B考查反義疑問句。原句應是：youwouldthinkhehadhaveforgotten…反義疑問句的規(guī)則是陳述部分是肯定式，疑問部分應是否定式。Wouldthink表示推測，疑問部分也應選擇would。選項B是正確的?！揪渥哟笠狻磕汶y道還認為他已經忘掉了，是嗎?

24.B

25.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——簡單句、并列句和復合句。例如：Hehastwodaughters.Theyaredoctors.(簡單句)Hehastwodaughtersandtheyaredoctors.(并列句)Hehastwodaughters,whoaredoctors．(復合句)

26.D

27.A解析：反問疑問句的陳述部分是肯定式時，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A是正確的。

28.A

29.C

30.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。

31.D

32.A解析：while意為“雖然”；as意為“因為”；if意為“如果”；since意為“因為”。根據(jù)題意選A。

33.A

34.C解析：much用在句中修飾比較級better。

35.A

36.A

37.D

38.D解析：從句中的問句主謂不倒裝。從句的時態(tài)隨主句。我想知道那輛車的價格。

39.Bsetout意為“出發(fā)，動身”。

40.B解析：本題考查固定搭配的用法。當否定詞位于句前時，得出結論應用reach/achievein/arriveatconclusion，故選B。

41.C解析：句子的前半部分是主語從句，主語從句中的謂語動詞時態(tài)應根據(jù)句意而定。

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

43.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，他就會在星期五以前到達那里。

44.C

45.C

46.D

47.A【句子大意】新打字機的價格是二手貨的三倍。

48.Blaunch為“發(fā)射”講；其余為干擾項。

49.D解析：forgetdoingsth．忘了已做過某事。注意區(qū)別forgettodosth。忘了而沒有做某事。

50.D本題考查時態(tài)。

【應試指導】句意：當你寫信回家的時候，請代我向你的妻子問好。在時間狀語從句中用一般現(xiàn)在時代替一般將來時。

51.E

52.Whatwouldyoulike?

53.F

54.H60.H

55.We’lltakeit

56.D

57.【提示】本題立足于日常表達。平日里，人們可用不同的說法表達相同的意思，因此此題比較靈活，答案不唯一，符合題意和口語表達方式即可。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，因此填入Wehaven’tseeneachotherforayear。2.【答案】Icameherethreedaysago【解題指要】根據(jù)中文提示，她說自己三天前才到這個地方，因此填入Icameherethreedaysago。3.【答案】Totellyouthetruth【解題指要】根據(jù)中文提示“說實話”，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月。因此該空填入l’llstayhereforamontho【參考譯文】Bill：請進。Alice：謝謝。Bill：我們有一年不見了吧，你最近怎么樣?Alice：嗯，還不錯。你呢?Bill：我也挺好的。Alice：我三天前剛到這里，就過來看看你。Bill：你真好。說實在話，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：我在這里要待一個月呢。我會再來看你的。

58.CJustrelax

這是有關準備面試的一段對話。

Pam：這是面試預備課的課堂嗎?

Instructor：就是這兒。請進。

Pam：我下周有面試，所以想盡快掌握相關知識。

Instructor：這里都是準備面試的。我們在面試時應當記住的是什么?

Pam：我認為應確保我們的最佳形象。

Instructor：對的，那么我們的友善態(tài)度和姿態(tài)呢?

Pam：是的，和善友好的姿態(tài)也會幫助我放松。

Instructor：你知不知道，在面試過程中你的問題和你的回答同等重要?

Pam：不知道。我還應當注意什么?

Instructor：放松就可以了。仔細聽問題，回答一定要誠懇。

59.EWouldyoulikemyhelp

這是有關學校里買教科書的一段對話。

Seamus：我在哪兒能買到課本?

Vic：你首先得有上課的書目。你有嗎?

Seamus：我有。

Vie：那好。有了書目，帶著它去書店。知道書店在哪兒嗎?

Seamus：不知道。

Vic：過了健身房，左手邊的第一個門就是。你知道舊書也可以賣嗎?

Seamus：是嗎?怎么賣?

Vic：把你用過的書帶上，把它們交給門口附近的代理人，他會給你錢的。你今天去嗎?

Vic：如果你今天或明天下午一點鐘能到書店的話，你買書時我可以幫你。需要我?guī)兔?

Seamus：不用，謝謝。我自己能行。

Vic：再見了。祝你一天順利!

60.B

61.D解析：這兒顯然要填一個形容詞來修飾Indians。full—blooded是復合形容詞，意為“純血統(tǒng)的”。

62.C

63.D根據(jù)前后兩個句子的意義及轉折關系可以判定應選D項。

64.D解析：此空前面有一個詞組“瞧不起(lookdownon)”，后面的一句又說如今對舊的方式又有新的自豪感(pride)。所以這里應選擇與自豪相反的詞，排除選項A和B。原文并未提及原有的生活方式遭到破壞，選項C排除。故選項D是正確的。

65.C解析：“thinkof”表示“認為，想”。

66.B解析：gotodosth表示“要做某事”。

67.B

68.D解析：這是以to引導的不定式做目的狀語，表示前一動作的目的。選項A、B不符語法規(guī)則；inexpressing這一動名詞結構不能表示目的，只能表示方式。

69.A根據(jù)上文內容可知，修車工早就預料到“我”會誤入歧途，因此應選A項。

70.B解析：引導定語從句，修飾thecamera-operator。

71.如果天氣許可,我們將明天清晨出發(fā).

72.正是這場洪水造成的后果使人們充分認識到植樹的重要性。正是這場洪水造成的后果使人們充分認識到植樹的重要性。
