同位语从句引导词是不是都用that

Question

如题所述

Answer 1

同位语从句一般用that,whether，what, which,who, when, where, why, how 等词引导，常放在fact, news, idea, truth, hope, problem, information, wish, promise,answer, evidence, report, explanation, suggestion, conclusion等抽象名词后面，说明该名词的具体内容。换言之，同位语从句和所修饰的名词在内容上为同一关系，对其内容作进一步说明。 

1. 如同位语从句意义完整，应用that引导同位语从句。（即that不充当任何成分，只起连接作用，不可省略）

The general gave the order that the soldiers should cross the river at once.

将军下达了战士们立即过河的命令。

2. 如同位语从句意义不完整，需增加"是否"的含义，应用whether引导同位语从句。（if不能引导同位语从句）

We'll discuss the problem whether the sports meeting will be held on time.

我们将讨论运动会是否会如期举行的问题。

3. 如同位语从句意义不完整，需增加"什么时候"、"什么地点"、"什么方式"等含义，应用when, where, how等词引导同位语从句。

I have no idea when he will beback.

I have no impression how he wenthome, perhaps by bike.

Answer 2

不是的。
最常用的引导词：
■ 用以引导同位语从句的最常用的连词是that。
如：
The news that we are having a holiday tomorrow is not true. 明天放假的消息不实。
The idea that you can do this work without thinking is wrong. 你可以不动脑筋做此工作的想法是错误的。
有时也可以用whether、连接代词或连接副词等来引导。
如：
It is a question how he did it. 那是一个他如何做的问题。
Do you have any idea where he lives? 你知道他住在哪里吗?
She had no idea why she thought of him suddenly. 她不明白她为什么突然想到了他。
We are not investigating the question whether he is trustworthy. 我们不是在调查他是否可信赖的问题。
■ 同位语从句可以用what引导
what不能用于引导定语从句，但可以引导同位语从句，尤其用于idea之后。
如：
Have you any idea what time it starts? 你知道什么时候开始吗?
I didn’t have the faintest idea what you meant. 我一点也不明白你是什么意思。
Do you have any idea what it means to be poor? 你知道贫穷意味着什么吗?

拓展：
同位语从句可以用which引导吗？
在定语从句中，若先行词为指事物的名词，有时既可用that来引导定语从句，也可用which来引导定语从句，但在同位语从句中，习惯上要用that，而不用which。
如：
我坚信他会获胜。
误：I hold a firm belief which he will win.
正：I hold a firm belief that he will win. 我得出结论这样做是不明智的。
误：I've come to the conclusion which it was unwise to do that.
正：I've come to the conclusion that it was unwise to do that.本回答被网友采纳
