that do,that doing,that done都可以

記得that是代詞時,所代指的東西=that）,它與後面的do的關系（主動,被動）決定了動詞的形式（doing or done）那 that do

I don't think that doing exercise is useful

It is a table that is made of wood .才對。表示被動的Be動詞不能省略

It/That/This is/was sb's first time doing sth. 這是某人第一次做某事。這是習慣表示方法，

It/That/This is/was the first time that sb has/had done sth. 這是正確結構。

以上二種結構可以互換，意義相同。

that從句中後面的動詞要變成ing形式。that 後接成分:引導目的狀語從句;引導結果狀語從句;引導原因狀語從句;引導讓步狀語從句，意為“雖然、儘管”; 引導條件狀語從句，意為“假使、假設

-般情況下作從屬連詞引導名詞性從句，從句可以用現在分詞做主語，謂語用三單。引導名詞性從句，狀語從句和強調句。

1. that名詞性從句

①引導賓語從句。及物動詞後的引導詞that可省略。
