宾语从句的引导词

宾语从句中的引导词一引入

宾语,位于谓语动词或者介词后。

•I know him.

•Do you have the time?

•I think (that) she is beautiful.

•Why don’t you pay attention to me?

二讲解

1、宾语从句的概念

从句在复合句中作宾语的名词性从句，

通常放在主句谓语动词（及物动词）或介词之后。eg. We know Mr Green teaches English.

She asked if these answers were right. /2、宾语从句三要素

引导词（连接词）语序时态

（一）引导词

由从属连词that 引导的宾语从句

由从属连词whether, if 引导的宾语从句

由连接代词Who,whom,whose,which,what

和连接副词where,how,why,when引导的宾语从句

（1）由从属连词that 引导的宾语从句

注：that 引导的从句，表示陈述一件事实，主句谓语动词表示确定，不疑问；that在句中无任何意义，不充当句子成分，常省略。

（2）由从属连词whether, if 引导的宾语从句

if/ whether “是否”，说明对陈述的事物不明确或不清楚。常用在ask, wonder, can(could) you tell me 表示疑问不确定意义的词之后；从句句意完整，不缺成分

（3）由连接副词where,how,why,when 引导的宾语从句

主句谓语动词，表示疑问不确定含义，要用疑问引导宾语从句，并在从句中担任句子成分，具有一定的意义，不可省略。
