(2) 由what, whether (if) 引导的宾语从句,例如:

(3) 动词+间接宾语+宾语从句。例如:

同位语从句有时可以不紧跟在它所说明的名词后面,而是被别的词隔开。
He got the news from Mary that the sports meeting was put off.
3. 同位语从句与定语从句的区别
(1) 定语从句中的that既代替先行词,同时以在从句中作某个成分(主语或宾语),而同位语从句中的that是连词,只起连接主句与从句的作用,不充当句中任何成分。
(2) 定语从句修饰限定先行词;同位语从句对名词进行具体内容的补充说明。“...的”
1) The news that he told me is that Tom would go abroad next year.
2)The news that Tom would go abroad is told by him.
同位语从句 定语从句
成分 that不做成分 that主,宾,表
作用 解释说明 对先行词起修饰作用,“…的”
省略 that 不能省 that在从句中做宾语时,可以省
that在同位语从句 与定语从句的区别
(I)试比较下面两个例句:
1.The suggestion that he raised at the meeting is very good.
2.The suggestion that the students should have plenty of exercise is very good.
(that引导定语从句, 作宾语, 可以省略)
(that引导同位语从句,在从句中不担当任何成分,但不可以省略)
辨别下列从句是定语从句还是同位语从句
1.We heard the news that our team had won.
2.We must face the fact that we had spent all our money.
