宾语从句中的that可以省略,定语从句中假如引导词that在从句中充当宾语,可以省略。
例如:宾语从句:I promise that I will study hard.这里的that可以省略。定语从句:This is the factory that we visited yesterday.这里的that可以省略。
  

扩展资料

  以下情况不可省略:

  1.that引导主语从句、表语从句、同位语从句时不能省略。

  2.宾语从句不止一个时,不能省略 如;they complain(that)they have to do homework from morning till night,that it is hard to study good,that they are very tired.是连续的宾语从句时,第一个可省,后面都不行。

  3.宾语从句与主语之间有插入语时,不可省。如:the teacher said,happy and firmly(插入语),that we must do homework.

  4.引导宾语从句是一个主从复合句。如:i belive that if i work harder,i will pass the exam.
