比较一下that在定语从句和宾语从句中的用法

reported a hypothesis that...

宾语为a hypothesis，that从句为同位语从句

感谢分享！！

看到OG中很多题目涉及到that在从句中的用法，想系统的总结一下，请教NN们对不对？

1。定语从句：从简洁方面考虑，that在从句中做宾语和that be结构都可以省略，that做主语不能省（是不是可以作为排除选项的标志，还不确定，大家可以一起讨论下）

OG 2 A: an area that is about C' size, ETS的解释说A is wordy, since that is can be deleted without loss of clarity

我觉得，这里是介词短语做定语和定语从句修饰哪个优先哪个更简洁的问题，所以应该是一起that is一起删除而不是说省略an area about C'size

OG 9 A,B: ...explosion, one that they believe..., ETS的解释that in A and B should be deleted, since the pronoun one is sufficient to introduce the modifier and the sentence is more fluid without that.

定语从修饰的词在定语中坐宾语可以省略

OG 1 D: a divorce that occurred...,ETS解释the phrasing a divorce that occurred when they were children correctly uses the relative clause that ocurred to modify a divorce,在这里，that是做主语，a divorce ocurred...

这道题that不能省略吧？请牛牛帮忙看一下能省略么？

2。宾语从句：一定不能省，例子就多了，如a study indicated that..., reported a hypothesis that...
