that一般可以引导名词性从句、定语从句。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。

  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

  1.定语从句中缺主语,修饰人时用who/that,修饰物时用which/that引导。如: Is this the factory which/that makes TV sets?The man who/that visited our school is from Australia.

  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.
