如题所述
that引导名词性从句时
(即主语、宾语、表语、同位语从句)
在从句中无具体含义,只起连接作用,而且在从句中也不作任何句子成分。它所引导的从句的句子结构和意义是完整的,而且从句一般是陈述一个事实。
例如:
①That she was able to come made us very happy.她能来使我们很高兴。
当that引导的主语从句或宾语从句太长时,常用it作形式主语或宾语而把that从句放在后面。
如: ①It is well—known that the earth is round.众所周知,地球是圆的。
that引导的主语从句,表语从句以及同位语中,that不能省略。
that引导的宾语从句,一般可以省去that,但在下面情况中不能省略。
1.在suggest,order等表示命令、请求、建议等动词后的宾语从句中,不能省。
2.由and或but所连接的两个引导的宾语从句时,第一个从句中的that可以省,第二个从句中的that不能省。
3.that引导的宾语从句,如果从句中还有其他状语从句,引导宾语从句的that不能省略。Tell him that if he is at home, I’ll call to see him.
2that引导定语从句要注意以下几点

2.从句中缺宾语,修饰人时用who/whom/that或省略引导词;修饰物时用which/that或省略引导词。如:Gone are the days which/that we spent together in the village.He is the man who/whom/that I think to be worthy of our praise.
