Section_ⅣGrammar_&_Writing

复习同位语

一、同位语

同位语是句子成分的一种，主要用于对名词进行解释与说明。可充当同位语的有名词(词组)、代词、数词、形容词(短语)、动名词(短语)、不定式(短语)及从句等。

1．名词、代词或数词充当同位语

I live with my uncle Tom.

我和汤姆叔叔住在一起。

We each put forward a proposal.

我们每人提出了一个建议。

She is the oldest among them six.

她是他们6人中年纪最大的。

2．名词词组、形容词(词组)、动名词(短语)、不定式(短语)等充当同位语

Zhu Zhiwen, a diligent farmer and brilliant singer, is really a hit throughout China.

朱之文，一位勤劳的农民、才华横溢的歌唱家，轰动了全中国。

Is this your purpose, to avoid being punished?

逃避惩罚，这就是你的目的？

二、同位语从句

在复合句中用作同位语的从句称为同位语从句。同位语从句是名词性从句的一种。它一般放在fact，news，idea，truth，hope，problem，information，belief，thought，doubt，promise，question等抽象名词的后面，对前面的名词作进一步的解释，说明前面名词的具体含义。

1．同位语从句的连接词

主要有that, whether, why, who, where, how, when等。其中that, whether不作成分，that无实际意义，whether意为“是否”；其他连接词具有实义，同时在同位语从句中作一定成分。引导同位语从句的连接词一般都不能省略。

The news that he was punished soon spread on the Internet.

他被惩罚的消息很快在因特网上传开了。

The problem whether we should continue to do the experiment has been solved.

我们是否继续做这个实验的问题已经被解决。

I have no idea where he lives.

我不知道他住在哪里。

②(浙江高考改编)The only way to succeed at the highest level is to have total belief that you are better than anyone else on the sports field.

③(江苏高考改编)The notice came around two in the afternoon that the meeting would be postponed.

④(重庆高考改编)Evidence has been found through years of study thatchildren’s early sleeping problems are likely to continue when they grow up.

2．同位语从句的注意事项

(1)分隔式同位语从句：有时同位语从句与其所解释说明的名词会被其他成分隔开，从而形成分隔式同位语从句，这样做主要是为了保持句子结构平衡，避免头重脚轻。

A saying goes that practice makes perfect.

熟能生巧是谚语。

(2)名词suggestion, order, demand, command, request等后的同位语从句要使用虚拟语气，即从句谓语用“(should＋)do”。

Our teacher gave us some advice how we (should) use the computer.

老师给了我们一些如何使用电脑的建议。

(3)名词doubt (怀疑)后的同位语从句用whether引导；no doubt (毫无疑问)后的同位语从句用that引导。

We have some doubt whether they can complete the task on time.

我们怀疑他们能否按时完成任务。

There is no doubt that Zhang Wei will keep his promise.

张卫会守信的，这是毫无疑问的。

3．同位语从句和定语从句的区别

which代替

whether/

how

不作成分，起连接作用“是否”；“如

何”

不引导定语从句

wh­类连

接词

作成分，起连接作用，有自己的含义，

但与先行词之间无关

作成分，起连接作用，没有自己的含义，

但是代替先行词在从句中作成分

吉姆得知整个村子都处在极度危险中的消息。(that引导同位语从句，解释说明the news 的内容)

Do you know the news (that/which) Jim told me?

你知道吉姆告诉我的那个消息吗？(that/which引导定语从句，且在从句中作宾语)
