參考答案

1.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廣引導的從句中，謂語動詞應(yīng)用“should+認”，should可以省去，再結(jié)合語態(tài)，故A項正確。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。

2.C

3.B

4.Blaunch為“發(fā)射”講；其余為干擾項。

5.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。

6.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)

7.B

8.D

9.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(yīng)根據(jù)句意而定。

10.C

11.A

12.B

13.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。

14.B

15.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，疑問部分也應(yīng)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(jīng)忘掉了，是嗎?

16.D

17.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。

18.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。”所以D項正確。

19.C

20.C解析：much用在句中修飾比較級better。

21.說到學英語，我越學越有興趣。AstoEnglishstudy,themoreIlearnthemoreinterestedIget/themoreinterestIhaveinit.
