引导主语从句的连接词主要有三类:1、从属连词:that、whetherThat he will come is certain (他会来是肯定的。

)这里的“that”在从句中不充当成分,只起引导作用。

Whether she will go there is not decided (她是否会去那里还没决定。

)“whether”表示“是否”。

2、连接代词:what、who、which、whose、whatever、whichever、whoever 等What you need is more practice (你需要的是更多的练习。

)“what”在从句中充当宾语。

3、连接副词:when、where、why、how 等When the meeting will be held has not been announced (会议何时举行还未宣布。

例如:It is unknown whether he will come (他是否会来还不知道。

高考英语名词性从句知识点一、that 从句1、主语从句(1)that 从句作主语时,常用it 作形式主语,常见的句型有:It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+ that从句It+be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, etc.)+ that 从句It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, etc.)+ that 从句(2)that可以省略,但 that 从句位于句首时,that不能省略。

复合句中具有名词性质并且可以做主语、表语、同位语或宾语的从句叫名词性从句。

因此,我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。

2、引导名词性从句的词叫引导词。

引导词可以分为以下几类:1)从属连词that(用于表示肯定的含义), whether, if (表示疑问),这三个词只起连接作用,不充当从句中的任何成分,除宾语从句外(that可省),这些词均不可省略。

2)连接代词有who, whom, whose, what, which, whoever, whatever, whichever等。

这些词在从句中既起连接作用,又充当从句中的成分,如主语、宾语、表语、补语,且不可省略。

3)连接副词有when, where, why, how, wherever, however等。

它们既起连词作用,本身又做从句中的状语。

3、名词性从句中的时态一致问题1)在宾语从句中,当主句是一般现在时、将来时或现在完成时,起从句的谓语根据需要用适当的时态。

当主句是一般过去时,从句用过去的某个时态,但若宾语从句表示客观真理,格言,谚语等,从句的时态仍用一般现在时。

Have you told him that when we are to leave?Teacher told us that China lies in the west of Japan.Although she was listening, she didn’t hear what he was saying because t here was so much noise.2)在主语从句、表语从句或同位语从句中,应注意主语从句中的谓语动词的时态一致性及动作发生的先后关系。
