定语从句注意事项。

定语从句注意事项

一、定语从句中宜用that而不用which 的情况

1．当先行词是不定代词或被形容词最高级,序数词（包括the first, the last等）或被any, much, few, some, the only, the very, little, no, every等修饰时[eg.] We should do all that is useful to the people.

[eg.] Do you mean the one that was bought yesterday.

[eg.] You can take any seat that is free.

[eg.] That is the very word that is wrongly used.

[eg.] This is only one of the evidences that reveal his crime.

[eg.] This is the third film that has been shown in our school this term.

[eg.] This is the best that can be done now.

[eg.] the most important thing that he should do is how to stop him from going on.

2．先行词既有人又有物。

[eg.] The writer and his novel that you have just talked about are really

well known.

3．先行词为表语的时候，或者关系带词本身是定语从句的表语，宜用that。

[eg.] This is a good book that will help you a lot.

[eg.] My home village is no longer the place that it used to be.

4.关系代词作表语（只限于限制性定语从句），只能用that引导

[eg.] My village is no longer the poor place that it used to be.

5.先行词是way, moment, reason, distance, time等时可用that,且可省略。

[eg.] I told him the way that he worked out the problem.

[eg.] All of the ways man had made to keep the city safe were gone in the thirty seconds the earth moved

6. 当先行词有the same,先行词和关系代词指同一事物时，用that.

[eg.] This is the same bike that I lost.

二.As引导的定语从句

1.在限制性定语从句中，as多和such/the same连用

[eg.] I bought the same pen as you bought the other day.(类似)

[eg.] this is such an exciting game as we all want to see.

( 比较This is such an exciting game that we all want to see it.)

[eg.] Such films as you describe can’t be shown at all.

2. 在非限制性定语从句中，as常与实义动词see, know, hear, watch, remember, say, tell, show, expect, guess等连用，as 指的是它前面的整个主句

[eg.] Shakespeare is a famous writer, as we all know.

[eg.] She is very patient, as is shown in his work.

注：在非限制性定语从句中，which, as 都可指代整个主句内容，as放在句首或句尾，但which只能放在句尾。

[eg.] There was a net bar around here. as I remember.

[eg.] The teacher praised him for his rapid progress , which made him very happy.

三.”介词+关系代词” 引导的定语从句

1) 介词+which（介词后不能加that）,常相当于when, where, why.

[eg.] The woman general still remembers the day on which she joined the army.

[eg.] This is the office in which I used to work.

[eg.] There are varieties of ways in which we can solve this problem. [eg.]I’d like you to explain the reason for which you were absent.

2) 名词/数词/代词/形容词最高级+介词+关系代词,通常在从句中作主语[eg.]China has thousands of islands, the largest of which is Taiwan Island. [eg.]I read some books, the covers of which are yellow with years.

3)介词+关系代词+名词

[eg.]He goes to bed at ten, at which time his brother locks all the doors and windows.

[eg.]Mark was a student at this university from 1999 to 2003,during which time he studied very hard and was made Chairman of the Student’ Union.

4)介词+whose +名词
