參考答案

1.D

2.C

3.B

4.D

5.B

6.C

7.Ainparticular是固定搭配,意為“特別地”。

8.D解析:上句責備瑪麗應(yīng)該做作業(yè)而不是坐到那兒看電視,下句是瑪麗對媽媽責備的一種辯解:“你說過電視是有教育意義的?!彼訢項正確。

9.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。

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

11.D本題考查時態(tài)。

【應(yīng)試指導(dǎo)】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。

12.B解析:cuts“裁減”;shortages“短缺”;weaknesses“弱點”;imports“進口”,故正確選項為B。

13.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。

14.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。

15.D

16.B

17.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。

18.C

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

20.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(jié)論應(yīng)用reach/achievein/arriveatconclusion,故選B。

21.C

22.A

23.C解析:much用在句中修飾比較級better。

24.Dapplyto應(yīng)用;applyfor申請

25.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?!痹谒膫€選項中,只有A項的justas有“正如,猶如”的意思。故選A。

26.B

27.A【句子大意】新打字機的價格是二手貨的三倍。

28.A

29.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”。

30.A

31.inthemeantime

32.wasqualifiedfor

33.Haditnotbeenforthetrafficjam/Butforthetrafficjamweshouldhavearrivedatthestationintime.Haditnotbeenforthetrafficjam/Butforthetrafficjam,weshouldhavearrivedatthestationintime.

39.IwenttotheGreatWallyesterday.Haveyoueverbeenthere?IwenttotheGreatWallyesterday.Haveyoueverbeenthere?

40.Idon'tknowifthereisoneboyinathousandmaybetwothousandwhocandoitthewayithastobedone.Idon'tknowifthereisoneboyinathousand,maybetwothousand,whocandoitthewayithastobedone.

44.curiosity

45.dependent

46.vaguely

47.stormy

48.enriched

49.establishment

50.regardless

51.B

52.Aalone意為“獨立,獨自”;lonely意為“孤獨的,荒涼的”;lone意為“孤獨的,寂寞的”;lonesome意為“孤單的”。根據(jù)題意,應(yīng)是獨自一個人工作。

53.A本題考查連詞辨析。

【應(yīng)試指導(dǎo)】句意:這個女孩幾乎沒來得及按門鈴門就突然被打開了,她的朋友們沖出去歡迎她。B、C、D三項在從句中不符合邏輯,故排除。

54.B這是由which引導(dǎo)的非限制性定語從句。

55.B本題考查動詞詞組辨析。

【應(yīng)試指導(dǎo)】句意:如果她履行了自己的諾言,她就會進入耶魯大學了。該句是由if引導(dǎo)的非真實條件句轉(zhuǎn)換而來的倒裝句,描述
