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 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
