That 有三種溝通功用:

(1)作為動詞後的補語標記

He told me [that he likes the girl.]

He said [that she is pretty.]

(2)作為關係子句內的關係代名詞

I've read the book [that tells a great story.] → that 代替子句主詞

I've read the book [that you bought yesterday.] → that 代替子句受詞

(3)作為名詞後同為補語的標記

I found out the fact [that he quit his job last month.]

省略 that 的原則為「不妨礙溝通」,只要 that 消失時不會造成理解困擾,通常是可以省略的。依此原則,只有兩種用法中 that 不可省略:

◆關係主詞不可省略

作為關係代名詞,代替主詞時不可省略。代替主詞時 that 標記關係子句中的主角,主角不能缺席:

I read the book that tells a great story. → 若省略 that,tells 就沒有主詞

◆同位修飾不可省略

作為同位修飾,出現在名詞後補充說明名詞語意時,that 不可省略。

同為修飾和前面的名詞為平行而重複的,若省略 that,兩個名詞性的成分就會重疊出現,有礙理解:

He mentioned the fact that [he quit his job last month.]

其他情況則比較自由,即便 that 不出現,仍可藉由其他成分偵測子句功能:

He thinks (that) she is pretty.

He told me (that) he has a crush on the girl.
