英语定语从句专项练习3（含讲解）
定语从句不同于单词作定语的情况，它需要放在被修饰的词（即先行词）之后。那么，先行词有哪些呢？
关于先行词你掌握得如何了呢？好了，小编不废话了，赶紧开始做下面的测试题吧！！
1.He is good at English， ______we all know.
A. that
B. as
C. whom
D. what
答案；B.
解析：as作关系代词可以单独用来引导非限制性定语从句。这时as所指代的不是主句中某个名 词，而往往指代整个主句的含义。as在从句中可以作主语、宾语。从句可放在主句后，也可置于主句前。 在本句中，as作宾语.
2.He talked a lot about things and persons ________they remembered in the school.
A. which
B. that
C. whom
D. what
答案：B.
解析：things和persons是先行词.当定语从句要修饰的先行词是既表示人，又表示物的名词时， 其关系代词要用that.
3.In our factory there are 2，000 workers， two thirds of ____are women.
A. them
B. which
C. whom
D. who
答案：C.
解析：two thirds of whom 即：two thirds of the 2，000 workers.
4.You’re the only person ______I‘ve ever met ______could do it.
A. who；/
B./； whom
C. whom；/
D./； who
答案：D.
解析：先行词person后有两个定语从句，第一个从句省略了关系代词whom.因为， whom作从句中 met的宾语，可以省略.第二个从句who could do it.who在从句中作主语，不可省略.
5.I lost a book， ______I can’t remember now.
A. whose title
B. its title
C. the title of it
D. the title of that
答案：A.
解析：whose title引导非限制性定语从句，whose title也可以说成the title of which
以上就是本期的英语巩固测试题。小编相信：每天练习一点，坚持就有成果。加油练习吧。
