[例1]The place______interested me most was the Children’s Palace.
A.which B.where C.what D.in which
【解析】答案A。定語從句中需要的是主語，隻能選用關係代詞，選項中which用作關係代詞，故答案選A。
[例2]Do you know the woman______？
A.whom I spoke B.to who spoke C.I spoke to D.that I spoke
【解析】答案C。“和某人講話”要說speak to sb。本題全句應為Do you know the woman whom I spoke to？whom是關係代詞，作介詞to的賓語，可以省略。
[例3]This is the hotel______last month.
A.which they stayed B.at that they stayed
C.where they stayed at D.where they stayed
【解析】答案D。定語從句中需要的是一個作地點狀語的關係副詞，where是關係副詞，表示地點。
[例4]Do you know the time______the Chinese Communist Party was founded？
A.which B.that C.when D.on which
【解析】答案C。when是關係副詞，表示時間，在定語從句中作時間狀語。
[例5]That is the day______I’ll never forget.
A.which B.on which C.in which D.when
【解析】答案A。定語從句中缺少的是賓語，which是關係代詞，可以作forget的賓語。其他幾個答案都不能作賓語。
[例6]He was the man______I supposed was capable of doing such a thing.
A.to whom B.of whom C.who D.whom
【解析】答案C。在這個句子中I supposed是插入語，插入語的位置很靈活，如果把它放到後麵這個題就顯得容易多了：He was the man______was capable of doing such a thing，I supposed。很顯然定語從句中所缺的是主語，而在選項中隻有C。
[例7]This is one of the best films______.
A.that have been shown this year B.that have shown
C.that has been shown this year D.that you talked
【解析】答案A。本句話的先行詞是films，因此，關係代詞that是複數概念，其謂語動詞應用複述的被動語態have been shown。如果句中的one前麵有the或the only修飾時that就視為單數。
