Question

同位语从句和定语从句中that的区别? that在句子中所做的成分

Answer 1

1.that即可代表事物也可代表人,which代表事物；它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词
2.代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all,anything,much等,这时的that常被省略
从引导词that来看
引导词that在同位语从句中是连词,只起连接作用,无具体词义,that不可省略；同位语从句的名词通常有new,idea,fact,promise,question,doubt,thought,hope,message,suggestion,word（消息）,possibility等.如：
I’ve come from Mr wang with a message that he won’t be able to see you this afternoon． 我从王先生那里来,他让我告诉你他今天下午不能来看你了.
