　　小升初英语语法定语从句知识点：主要考点

　　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。
