[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。定语从句中需要的是主语，只能选用关系代词，选项中which用作关系代词，故答案选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。“和某人讲话”要说speak to sb。本题全句应为Do you know the woman whom I spoke to？whom是关系代词，作介词to的宾语，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。定语从句中需要的是一个作地点状语的关系副词，where是关系副词，表示地点。

[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是关系副词，表示时间，在定语从句中作时间状语。

[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。定语从句中缺少的是宾语，which是关系代词，可以作forget的宾语。其他几个答案都不能作宾语。

[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。在这个句子中I supposed是插入语，插入语的位置很灵活，如果把它放到后面这个题就显得容易多了：He was the man______was capable of doing such a thing，I supposed。很显然定语从句中所缺的是主语，而在选项中只有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。本句话的先行词是films，因此，关系代词that是复数概念，其谓语动词应用复述的被动语态have been shown。如果句中的one前面有the或the only修饰时that就视为单数。

[例8]Can you lend me the book______the other day？

A.about which you talked　B.which you talked

C.about that you talked　D.that you talked

【解析】答案A。“谈到某事物”应说talk about sth。about是介词，其后要用which作宾语，不能用that。

[例9]The pen______he is writing is mine.

A.with which　B.in which　C.on which　D.by which

【解析】答案A。with有“用”的意思，介词之后只能用which，不能用that。with which在定语从句中作状语，即he is writing with a pen。

[例10]They arrived at a farmhouse，in front of______sat a small boy.

A.whom　B.who　C.which　D.that

【解析】答案C。很显然这是个非限制性定语从句，先行词又是指的是物，that不能引导非限制性定语从句，所以答案只能是in front of which 即in front of a farmhouse。故选C。

[例11]The engineer______my father works is about 50 years old.

A.to whom　B.on whom　C.with which　D.with whom

【解析】答案D。定语从句中缺少的是宾语，work with sb意思是“和某人一起工作”，with放在前面。with whom放在从句中即为：my father works with the engineer。故答案为D。

[例12]Is there anyone in your class______family is in the country？

A.who　B.who’s　C.which　D.whose

【解析】答案D。定语从句中所需要的是作定语的成分，whose引导定语从句，在从句中作主语family的定语。

[例13]I’m interested in______you have said.

A.all that　B.all what　C.that　D.which

【解析】答案A。主句中介词in缺少宾语，定语从句中也缺少宾语，C、D排除，在B项中all能做in 的宾语但是what 不能做关系词。故选A。

[例14]I want to use the same dictionary______was used yesterday.

A.which　B.who　C.what　D.as

【解析】答案D。the same…as是固定用法，as引导定语从句时，可以作主语、宾语或表语。在本句话中，as作从句的主语。

[例15]He isn’t such a man______he used to be.

A.who　B.whom　C.that　D.as

【解析】答案D。such…as是固定用法，as引导定语从句时，可以作主语、宾语或表语。在本题中，as作表语。故答案为D。
