同位语从句的先行词通常为question, thought, report, belief, decision, doubt, answer, hope, fact, truth, belief, news, idea, promise, information, opinion, theory, conclusion, order, suggestion, problem,等抽象名词。英语中引导同位语从句的词通有连词that, whether,连接副词 how, when, where等,今天小编为大家讲解的是同位语从句的引导词以及需要注意的几个问题,供大家参考,希望对同学们的学习有所帮助,下面跟小编一起来学习下吧!

1、引导词
(1)由that引导
They were worried about the fact that you were sick. 他们为你生病发愁。
I’ve come to the conclusion that it was unwise to do that. 我得出结论这样做是不明智的。
(注:在某些名词,如demand, wish, suggestion等后面的同位语从句要用虚拟语气。如There was a suggestion that Tom should be dropped from the team. 有一项建议是汤姆应该离队。)

(2)由whether引导
He must answer the question whether he agrees to if or not.
他必须回答他是否同意这样一个问题.
There is some doubt whether he will come. 他是否会来还不一定。(注:if不能引导同位语从句)

(3)由连接副词引导
引导同位语从句的连接副词通常有how, when, where, why等。
He had no idea why she left. 他不知道她为什么离开。
The question where we shall have a meeting hasn't decided. 我们到什么地方去开会,这个问题没有决定。

(4)由连接代词引导
Have you any idea what time it ends? 你知道什么时候结束吗?

此外,还应注意以下几点问题:
1、有时同位语从句可以不紧跟在说明的名词后面,而被别的词隔开。
The thought came to him that maybe the enemy had fled the city. 他想到可能敌人已逃离这座城市。

2、同位语从句与其所修饰的名词之间是一种同位关系,二者之间存在逻辑上的系表关系,可用“主+系+表”结构来表示.例如:
The news that he won the first place is true. 他赢得冠军的那个消息是真的.
上句若用“主+系+表”结构来表示,则是:
The news is that he won the first place. 消息是他赢得了冠军.
意思合理,系表结构成立,故为同位语从句。

3、同位语从句一般都与抽象名词同位,一般没有复数形式。

好了,以上就是小编今天带来的讲解内容,对于同位语从句的学习,还希望同学们能多加用心,看似很简单的问题,往往越容易出错。因此,小编在这里提醒大家,平时要多下功夫,一些细小的知识点也要注意到,做题时一定要细心审题,慢慢有所进步。
