非限制性定语从句和同位语从句

同位语从句讲解与练习

1定义：用作同位语的从句叫做同位语从句，用以解释说明某一名词内容和实质的从句。 2.连接词：that, whether, why, who, where, how, when等。引导同位语从句时一般都不省略。 if一般不引导同位语从句that, whether不作成分，whether表示“是否”

E.g. They were all very much worried over the fact that you were sick.对你生病这件事，他们很 焦虑。

非限制性定语从句

限制性定语从句的概念： 限制性定语从句对先行词起限制或修饰的作用，是先 行词在意义上不可缺少的 定语 ，如果去掉，主句的意 思就不完整或失去意义。从句和主句的关系密切，写 时不用逗号分开。例如： eg: This is the soldier who saved the boy’s life.先行词 引导词

定语从句

非限制性定语从句的概念： 非限制性定语从句只是对先行词作些附加的说明, 如果 去掉, 主句的意思仍然清楚。和主句关系不十分密切， 从句和主句之间用逗号分开。 例如：

Rome , which is the capital of Italy, has a very long history.罗马是意大利的首都，有着非常悠久的历史。

which与as引导非限制性定语从句的异同

which与as引导非限制性定语从句的异同

which与as一样，都可以引导非限制性定语从句，它们既有相同之处，也有差别。因此在实际运用中容易混淆。它们的某些用法在高考中也会考查。

一．相同点。

两者引导非限制性定语从句时，可指代主句中的部分或整个句子的内容，在从句中做主语，宾语或表语，位于主句之后有时可互换。 The meeting was put off, as /which was exactly what we wanted. He was a doctor, as/which I knew from his manner.

二． 不同点

1. as可指其前后主句提到的事实或情况，因此引导的非限制性从句位置比较灵活，which可以放在主句前后，也可插入主句之中；而which引导的非限制性从句只能位于主句之后。

As is known to all, fish can’t live without water.

Air, as we know, is gas.

2.在非限制性从句中，which后的be动词不可省；as而后的be动词可以省略。

She told me she won the match , whi

怎样区别定语从句和同位语从句 - 六级语法

在英语复合句中，有些定语从句和同位语从句从表面形式上看非常相似，使许多人难以分辨彼此。本文拟从先行词和引导词两个方面对二者进行区别。 一、先行词

1．定语从句的先行词是名词或代词；而同位语从句的先行词只能是名词，而且仅限于idea，plan， fact，theory，promise，hope，news，doubt，truth，information，suggestion，question， thought，belief，conclusion等少数名词。例如：

①The boy who is playing football is my classmate． ②Those who work hard will succeed．

③The fact that he had not said anything surprised everybody． ④The fact that you are talking about is important．

在①句中，划线部分是定语从句，其先行词是名词 boy，它不能用作同位语从句的先行词。 在②句中，划线部分也是定语从句，其先行词是代词tho

同位语

一个名词(或其它形式)对另一个名词或代词进行修饰，限定或说明，这个名词(或其它形式)就是同位语。同位语与被它限定的词的格要一致，并常常紧挨在一起。

1. 名词作同位语

Mr. Wang, my child’s teacher, will be visiting us on Tuesday. 2.短语作同位语

I, the oldest girl in the family, always had to care for the other children. 3. 直接引语作同位语

But now the question comes to their minds, “Did she die young because she was a clone?” 但是现在他们不得不思考这样的问题：“多莉早死是因为它是一只克隆羊吗？” 4. 句子作同位语

The girls were surprised at the fact that ocean ships can sail up the Great lakes.巨大的海轮可以开到五大湖，让表姐妹俩感到吃惊。
