什么是定语从句英语语法 英语语法：高考英语定语从句的主要考
考点一 考查关系代词whose引导的定语从句
1. A person ________ e-mail account is full won’t be able to send or receive any e-mails. (天津卷)
A. who B. whom C. whose D. whoever
【解析】C。在所给的四个关系代词中，只有whose能用于名词用作定语，故选C。又如：A bookseller is a person whose job is selling books. 书商就是其职业是卖书的人。
2. Many children, ________ parents are away working in big cities, are taken good care of in the village. (安徽卷)
A. their B. whose C. of them D. with whom
【解析】B。their是物主代词，不是关系代词，不能引导定语从句，所以不能选;在其余三个选项中，只有whose能用于名词用作定语，故选B。句意为：许多孩子的父母外出到大城市打工去了，他们在家乡被照顾得很好。
3. I was born in New Orleans, Louisiana, a city ________ name will create a picture of beautiful trees and green grass in our mind. (湖南卷)
A. which B. of which C. that D. whose
【解析】D。在所给定的四个关系代词中，只有which和whose能用于名词用作定语，故可排除B和C。而关系代词which和whose用于名词前作定语的区别是：which具有that或this的语义特征，而whose则具有one’s的语义特征。
考点二 考查关系代词which引导的定语从句
1. They’ve won their last three matches, ________ I find a bit surprising. (辽宁卷)
A. that B. when C. what D. which
【解析】D。that不用于引导非限制性定语从句，故被排除;when可引导非限制性定语从句，但只用于指时间，与句意不符，故也被排除;而what不是关系代词，不能用于引导定语从句，故也被排除;which在此引导非限制性定语从句，并在定语从句中充当动词find的宾语。句意为：他们赢了最后三场比赛，我发现这有点令人吃惊。
2. My friend showed me round the town, ________ was very kind of him. (全国Ⅱ)
A. which B. that C. where D. it
【解析】A。由于两个句子之间没有并列连词，所以不能选B或D;而where是关系副词，不能用作主语;which在此引导非限制性定语从句，并在从句中用作主语。又如：Peter drove too fast, which was dangerous. 彼得开车很快，这是很危险的。
3. Whenever I met her, ________ was fairly often, she greeted me with a sweet smile. (山东卷)
A. who B. which C. when D. that
【解析】B。that不能用于引导非限制性定语从句，故可排除;when是关系副词，不用作主语，故也可排除;who用于指人，但这里的定语从句不是修饰her，而是修饰whenever I met her，故不能用who，此处应用which。又如：He said that he had never seen her before, which was not true. 他说他从没见到过她，这是不真实的。
