于一个名词因此，这四种从句通称为名词性从句。引导名词性从句的连接词可分

连接副词：when, where, how, why

名词性从句连接词的选用
(一) that 和 what的选用：
that 和 what都可引导所有的名词从句。但是，what除起连接作用外，还在名词性
从句中充当成分，可做 从句的主语、宾语、或表语。而that在名词性从句中不充
当任何成分，只起连接作用。

（三）其它连接代词和副词的连用

why、how 等连接词，这些连接词既具有疑问含义，又起连接作用，同时在从句
中充当各种成分。

that不可省略的情况：
a. 主语从句
b.表语从句
c.同位语从句
d.用it做形式宾语的宾语从句

2.能接同位语从句的名词有：fact、idea, news, information, order, belief, suggestion,
advice等.
3.连接词通常是that,也可根据含义选用 whether, what, when, where 等来引导同位
语从句.

exercise.

5. I have some doubt ________ he will win.


（六）同位语从句和定语从句的区别
1.定语从句是先行词的修饰语，它不涉及先行词的具体 内容。定语从句中that不但
起连接作用，而且在定语从句中充当一个句子成分，充当从句的宾语成分 时可省
略。

2.同位语从句对中心词的内容作进一步的解释和说明，表明中心词的 具体内容。引
导同位语从句的that 在同位语从句中不做任何成分,只起连接作用,无具体含义,且
不可省略.
1）.We expressed the hope that they had expressed.
2）. We expressed the hope that they would come to China again.
1）.The information has been announced that more middle school graduates will be
admitted into university.
2）.The information that he revealed at the meeting is of great value.

3.名词demand, suggestion, proposal, advice等词后的同位语从句的语气要用虚拟语
气,结构为 should + do, should 可省略
He gave me a suggestion that I ( should ) be calm now.

（七）注意宾语从句中的时态呼应

当主句动词是现在时，从句根据自身的句子情况，而使用不同时态。
例如:
I know (that) he studies English every day. (从句用一般现在时)
I know (that)he studied English last term. (从句用一般过去时)
I know (that) he will study English next year. (从句用一般将来时)
he has studied English since 1998. (从句用现在完成时)

当主句动词是过去时态(could, would除外)，从句则要用相应的过去时态
例如:
The teacher told us that Tom had left us for America.(从句用过去完成时)
The teacher told us that Tom was sleeping.(从句用过去进行时)
总结：主句：现在时，从句：啥时态都可； 主句：过去时，从句：过去时
