第1讲 引导名词性从句的连接词
考点1. 引导名词性从句的连接词有哪些
有学生认为，引导同位语从句只能用that, 这句话对吗？先看下面几个句子。
① I have no question that he will come. ② I have a question whether he will come ③ I have a question when he will come.
我们可以看出：上面三个句子中question后面都是同位语从句，都是说明question的内容的。
在句①中，同位语从句的原句是陈述句，由that引导； 在句②中，原句是一般疑问句，由whether引导； 在句③中，同位语从句的原句是特殊疑问句，特殊疑问词也起着连接作用。
其实，所有名词性从句的连接词都有上面的三种情况。 宾语从句：
I don’t know that he will come.
I don’t know whether/if he will come. I don’t know when he will come. 表语从句：
What I don’t know is that he will come. What I don’t know is whether he will come. What I don’t know is when he will come. 主语从句
That he will come is obvious.
Whether he will come isn’t known yet. When he will come isn’t known yet.

主语从句、表语从句、同位语从句中连词that不能省略。 That they are good at English is known to us all. The problem is that we don’t have enough money.
She expressed her hope that they would come to China one day.
只有宾语从句中的连接词that可省略，但在以下几种情况中that也不能省略：
A. 当that从句和主句谓语动词之间有插入词语或者从句主
语之间有插入语时，that不可省略。
He judged that, because he was a child, he did not understand.
B. 当两个名词性从句并列作宾语时，后面的that不能省。

考点4. question 与doubt 后跟同位语从句时的连接词问题
doubt，question用于肯定结构时，后面用whether引导名词性从句；用于否定结构或疑问结构时，后面用that引导名词性从句。be sure 用于肯定句或疑问句时，后接that引导的名词性从句；用于否定句时，后接whether/ if引导的名词性从句。

考点3. whether 与if引导名词性从句时的区别
A. 在主语从句、表语从句、同位语从句中只能用whether,
不能用if。
Whether the meeting will be put off has not been decided yet.
The question is whether they have so much money.
We ought to discuss carefully the question whether we can do it or not.
B. 在宾语从句中whether和if可以互换，但： i. 作介词宾语时连接词一般用whether。如：
It all depends on whether they will come back. ii. 后面直接跟or not 时用whether。如：
I didn’t know whether or not he had arrived in Wuhan. C. whether也可与动词不定式连用，但if不能。
I have not decided whether to go or not.
D. whether常与or连用表示一种选择，if不能这样用：
The question of whether they are male or female is not important. E. whether可引导一个让步状语从句表示“不管”、“无论”，
而if不能。如：
Whether he comes or not, we will begin our party on time. F. discuss后通常用whether。

25. After three days’ waiting, there was a little doubt in the
mother’s mind ______ the police could find her lost child. A. how B. that C. where D. whether 考点5. 名词性从句是复合句时，不要忘了带that (双连接词) 改错:
① The question was that whether he could get a job at the center. ② You have no idea that how busy we were those days. ③ It is well known what a person eats causes changes in the
body. 答案及解析：
①去掉that,。后面whether本身就起着连接作用。 ②去掉that。 who, how, when, what等本身就有两个作用：作从句的成分；起连接作用。
③在what前面加that。what只是把主语从句的两个分句连接起来，但其作为一个整体来作主语从句时还需要用that引导。
