《Theme parks （Part 4）》
同位语从句
名词性从句包括:主语从句
宾语从句
表语从句
同位语从句
同位语从句之概念:
1.在句中起同位语的作用。
①一般放在名词fact/news/idea/promise/thought/suggestion/demand/等之后,用以说明或解释前面的名词。
②同位语从句一般用连词that,whether;代词 what,who;副词 when,where,why,how等词引导
We heard the news that our team had won.
We heard the news that is interesting to us.
The problem whether it is right or wrong has not yet been decided.
I have no idea where he lives.
The question who will take his place is not clear.
I have no idea where he lives.'
The question who will take his place is not clear.
I have no idea what he is doing.
同位语从句之that:
2.that 引导同位语从句时,that不能省略。
We must face the fact that we fail.
The thought that we might succeed excited us.
The idea that they should try a second time is worth considering.
注意:
1.有时同位语从句不是直接跟在名词后面,而是被其他词隔开。
World came that they had won the game.
The thought came to him that maybe the enemy had fled the city.
2.名词suggestion,advice,order等词后的同位语从句的谓语动词要用should+动词原形,should可省略。
The suggestion that the plan(should) be delayed will be discussed tomorrow.
试比较:
1）He put forward the suggestion that the second question should be discussed first.(同位语从句)
2）The suggestion that he had put forward was turned down.(定语从句)
同位语从句与定语从句的不同之处
1）、从句的作用不同:
The news that our team has won the final match is encouraging.
The news that you told us is really encouraging.
2）、引导从句的关联词that的功能不同:
①Dad made a promise that he would buy me CD player if I passed the English test.
(that不充当任何成分)
②Dad made a promise that excited all his children.
3）、同位语从句中引导词可为what,而定语从句中不能用what作为关系代词,而用which,that。
I have no idea what we should do first
