. Conclusion 1 1.限制性定语从句与先行词关系

（A:密切;B:不密切），是先行词

(A:可缺少;B:不可缺少)的部分, 去掉它，主句意思

(A:不明确;B: 明确.)翻译时,从句先译,“…的”

2.非限制性定语从句是对先行词的补充说明,去掉

（A:会影响;B:不会影响）主句的意思。翻译时，主句先译，从句单独成句．

注意：

和

不能引导非限制性定语从句。（

可用

来代替，eg:I have told them the reason,

I didn’t attend the meeting.）

思考:这两句可否去掉逗号

变成限制性定语从句？

Example2: 1).China, which is founded in 1949, is becoming more and more powerful. 2).His father, who works in Changsha, came back yesterday. 能变成限制性定语从句吗？？

Answer

.（yes，no）

Example3: 1).He has three sons, two of whom are doctors. 2).Many people, some of whom are slim, are going on diets. 3).China has hundreds of islands, the largest of which is Taiwan.

Conclusion 3 “介词+关系代词”在句中的用法：

1.名词

2.数词(含基数词，序数词，分数和百分数）

+of +which / whom, 3.代词(代词有many/all/both/none/neither/either/some/any/ a few等）

4. the+adj最高级, the last 此时先行词在其后的定语从句中作介词的宾语,关系代词不可用

. Practice: 1,There are 70 students in our class, 36 of

are boys. 2,I got three gifts on Christmas Day, the biggest of

was given by my brother. 3,I’m doing various exercises, all of

are quite helpful to my health.

Step3

Complement

引导非限制性定语从句时as与which的异同：

观察：

1). As we all know, light travels much faster than sound. 2). Light, as we all know, travels much faster than sound.

2

3). Light travels much faster than sound, as we all know. 4). He changed his mind, which made me very angry. 5).As is reported in the newspapers,talks between the two countries are making progress.

相同点：

1.都可指代

; 2.都可在句中作

,

或

.

不同点：

1.as引导的从句可位于

,

,

.而which引导的从句只可放在

. 2.as有

之意，而which没有.

as和which的区别

1．as含有正如、按照、正像之意，as一般用在肯定句中，而which则可以用于含否定意义的句子中，如：

1).He failed in the exam again，as was expected

2).He failed in the exam again，which was unexpected．

2.当说明主句的事件引起的结果时用which，如：

1).He saw the girl，which delighted him．

2).He didn’t pass the exam，which made his mother angry．

3．下列固定结构，一般不能用which，如：

as has been said before

as often happens

as is well known

as will be shown as may be imagined

as we know

as follows

as we expected

as he pointed out

as is given

as we have seen

as is said about…

as we all can see 多数已成固定结构

4.

as常用于the same...as, such... as , as... as和so...as 结构中。如：

1）I have never seen such a lazy man as you (are ).

2）Let children read such books as will make them better and wiser.

3) Take as many as you want. （作宾语）

4) Here is so big a stone as no man can lift. （作宾语）

注意：the same...后既可以用that 也可以用as来引导定语从句,that“同一的”即指同一事物；而后者引导定语从句时，

as“相似”即指同类事物。如：

1) This is the same pen that I lost yesterday.

(This sentence means: This pen is mine. I lost it yesterday.) 2) This is the same (kind of)pen as I lost yesterday.

(This sentence means: This pen is very much like mine that I lost yesterday. In fact, it isn't mine.)
