典型例題及解析

  [例1]We were not surprised at______，for he had worked so hard.

  A.what has he achieved　B.that what he had achieved

  本章節來源於𝖻𝖺𝗇𝗑𝗂𝖺𝖻𝖺.𝖼𝗈𝗆

  C.what he had achieved　D.that he had achieved

  【解析】答案C。at是介詞，其後接賓語從句時，從句要用陳述句的語序。achieve是及物動詞，what在從句中作賓語，所以選C。that在從句中只起連接作用，無意義。

  [例2]______I saw was two men crossing the street.

  A.What　B.Whom　C.Who　D.That

  【解析】答案A。本句中的主語是主語從句，what在從句中作賓語。

  [例3]Would the news______he failed to pass the exam bother you？

  A.which　B.that　C.of which　D.on which

  【解析】答案B。由於從句he failed to pass the exam 是news的內容，所以這是一個同位語從句，應該用that引導。

  [例4]The fact ______he does so in so short period of time challenges explanation.

  A.why　B.that　C.what　D.which

  【解析】答案B。fact後的從句講的是fact的內容，所以是同位語從句，引導同位語從句的連詞只能使用that。

  [例5]The old gentleman never fails to help______is in need of his help.

  A.whom　B.who　C.whoever　D.whomever

  【解析】答案C。本句中需要填入一個連接代詞引導賓語從句，且此代詞要在從句中作主語。A、D都只能作賓語。whoever引導賓語從句。who也可以引導賓語從句，但whoever強調無論誰。

  [例6]______was unimportant.

  A.Whether he enjoyed our dinner or not

  B.No matter how he enjoyed our dinner

  C.If he enjoyed our dinner

  D.What he enjoyed our dinner

  【解析】答案A。本句中包含一個主語從句，意思是「他是否喜歡我們的飯不重要」。只有A最符合題意。B、C中的No matter how 和If 都引導狀語從句；D項中的what在從句中作主語或賓語，而本從句中有主語和賓語。

  [例7]How long do you think______to finish this urgent task？

  A.did it take you　B.it will take you

  C.will it take you　D.it to take you

  【解析】答案B。think後接賓語從句。從句不倒裝。

  [例8]______was not the way the event happened.

  A.Which the press reported　B.That the press reported

  C.What did the press report　D.What the press reported

  【解析】答案D。此處需填入一個主語從句。在這個主語從句中作動詞report的賓語應該用連接代詞what。

  [例9]No one doubts______it is true.

  A.whether　B.if　C.that　D.what

  【解析】答案C。doubt用在肯定句中後接if引導的從句，用在否定句中後接that引導的從句。

  [例10]There is much chance______Bill will recover from his injury in time for the race.

  A.that　B.which　C.until　D.if

  【解析】答案A。that在此引導同位語從句，修飾chance，又如：There was a chance that my letter would arrive in time.我的信有可能準時到達。

  [例11]We haven’t settled the question of______it is necessary for him to study abroad.

  A.if　B.where　C.whether　D.that

  【解析】答案C。根據句意，空格處應填一個表示「是否」的詞，但在A和C兩個表示「是否」的選項中，if不能用於介詞後，故選C。

  [例12]— Could you do me a favour？— It depends on______it is.

  A.which　B.whichever　C.what　D.whatever

  【解析】答案C。what在此引導賓語從句，what在賓語從句中用作表語，句意為：這要看是什麼（即這要看你要我幫什麼忙）。

  [例13]____makes this shop different is that it offers more personal services.

  A.What　B.Who　C.Whatever　D.Whoever

  【解析】答案 A。what在此引導主語從句，意思上相當於the thing that。

  [例14]______team wins on Saturday will go through to the national championships.

  A.No matter what　B.No matter which

  C.Whatever　D.Whichever

  【解析】答案D。從句意上看，應為一個表示「無論哪一個」的選項，因此B和D比較合適，但No matter which只用於引導狀語從句，不用於引導名詞性從句，故不能選B。

  [例15]—It’s thirty years since we last met.—But I still remember the story，believe it or not，______we got lost on a rainy night.

  A.which　B.that　C.what　D.when

  【解析】答案B。that在此引導同位語從句，修飾名詞the story。此題的難點是，其中插入了believe it or not，使問題變得複雜了。
