高三英语教案 定语从句备考复习教案

(10全国Ⅱ)16. I refuse to accept the blame for something _____was someone else’s fault. 【B】

A. who   B. that   C. as   D. what

定语从句的常见考点：

⒈ one of + the +复数名词　后面定语从句中谓语单复数情况：

跟定语从句所靠近的那个复数名词在数上保持一致，通常用复数。但如果这一结构前面有the only之类的限定语，后面定语从句的谓语动词则要用单数形式。

This is one of the books that are required for study at school.

He is the only one of the teachers who knows French in our school.

⒉ 定语从句中用that而不用which的情况：

1)、先行词是不定代词时，如：everything, anything, any, something, little, much等。

We should do all that is useful to the people.

2)、先行词被all, every, no, some, any, much等词修饰时。

I have read all the books that you gave me.　。

3)、先行词被形容词最高级或序数词修饰时。

This is the most interesting film that I have ever seen.

4)、先行词被the only, the very, the same, the last修饰时。

This is the very book that I want to find.

5)、先行词既有人又有物时。

They are talking about the factory, the leaders and the workers that they visited yesterday.

6)、主句是以who 或which 开头的疑问句时。

Who is the person that is standing at the gate?

7)、关系代词本身是定语从句的表语时。

My hometown is no longer the place that it used to be.

⒊ 定语从句中宜用which而不用that 的情况：

1)、当关系代词前面有介词时。

Is this the room in which he lives?

2)、在非限制性定语从句中。

(2011•浙江卷)8.English is a language shared by several diverse cultures ,each of____ uses it somewhat differently .【A】

A.which  B.what     C.them    D.those

3)、当关系代词后面有插入语时。

Here is the English grammar book which, as I had told you, will help improve your English.

在一个句子中有两个定语从句，其中一个定语从句的关系词用了that，另一个宜用which。

Let me show you the novel that I borrowed from the library which was newly opened to us.

给你看看我从新开放的图书馆借来的一本小说。

⒋ 关系代词as 和which的选用：

在形式上as引导的非限制性定语从句可位于主句的后面，也可位于主句的前面，而which引导的非限制性定语从句可位于主句的后面，不能位于主句的前面;在意义上，as定语从句和主句的关系一般为一致关系，常译为“正如…，就象…”，而which定语从句和主句的关系是因果关系，或which从句是对主句的评论。

The room hasn’t been cleaned for weeks, which makes it  very dirty.

He was late again, as we had expected.　　他又迟到了，正如我们所料。

另外，在such…as…, the same…as…, as…as, so…as等结构中，as引导定语从句，此时不能用which代替。(这种定语从句常采用省略形式)

I have never seen such a lazy man as you.我从来没见过你这样懒的人。

Here is so big a stone as no one can lift.　这个大石块太大没人能把它举起来。

⒌ 先行词为situation、case、occasion、point时，常用where引导定语从句。

Can you point out a situation where this word can be used?　你能指出这个单词使用的场合吗

You have got to the point where a change is needed.　你已经发展到非改不可的地步了。

⒍ 关系代词在定语从句中作主语时，谓语动词要和先行词的性、数保持一致。

(2011•山东卷)32.The old town has narrow streets and small houses _____are built close to each other.【D】

A.they   B.where C.what   D.that

⒎ 定语从句中不要重复了关系代词或关系副词所替代的部分。

误：Thi s is the place that I have visited it.

这就是我参观过的那个地方。

应去掉it, 因that 代替先行词the place 在定语从句中作visit的宾语，再加it就是多余的了。

⒏ 定语从句中不要加多余的关系副词或介词。

误：The house where he lives in needs repairing.

应删去关系副词where, 因为where在这里的意思是in which, 否则介词in就重复了。或保留where, 删去从句里的in.

由“介词+关系代词”引导的定语从句

1. 由“介词+关系代词”引导的定语从句主要用于正式文体，在非正式文体中通常将介词放至句末。如：This is the man to whom I referred. 我指的就是这个人。This is the man (whom) I referred to. 我指的就是这个人。

2. 直接用于介词后作宾语的关系代词which不能换成that，直接用于介词后作宾语的关系代词whom不能换成who。但若介词用于句末，则用作宾语的which, whom也可换成that, who，或者省略不同。如：这是一个我们讨论了许多的问题。(which不能换成that，也不能省略)This is a subject which we have talked about a lot. 这是一个我们讨论了许多的问题。(which可以换成that，也可以省略)

3. 关系副词when, where, why根据情况有时可换成“介词+关系代词which”。如： That is the day when [=on which] he was born. 那就是他出生的日子。That is the house where [=in which] he lived. 那就是他住过的房子。That is the reason why [=for which] he must apologize. 那就是他必须道歉的原因。4. 在很正式的文体中，“介词

4. +关系代词”引导的定语从句可紧缩成“介词+关系代词+不定式”结构。如：在那儿孩子们有个玩耍的花园。正：There the children had a garden in which to play. (很正式)正：There the children had a garden in which they could play. (较正式)正：There the children had a garden to play in. (较口语化)注：这类“介词+关系代词++不定式”结构中的介词不能没有，也不能放在句末。如不能说There the children had a garden which to play in.

定语从句关系词省略的6种情形

定语从句中关系词省略的6种情形关系词有时可以省略，但这只限于限制性定语从句中，在非限制性定语从句中，关系词则不可省略。

一、关系代词作宾语时的省略当关系代词who, whom, which和that在定语从句中用作动词宾语或介词位于句末时的介词宾语时，可以省略。如：在定语从句中用作动词宾语或介词位于句末时的介词宾语时，可以省略。如：Is there anything (which) you wanted? 想要什么东西吗? Who is the man (that / who / whom) you were talking to? 刚才和你讲话的人是谁?
