課本中不會教你的[T]656　That's all，That's it，That's that和Is this it

656　That's all，That's it，That's that和Is this it

① That's all在這句中，表語all意為“一切，全部”，all為名詞，全句意為“沒有別的話（事）了，完了”。That's all的疑問句是Is that all？（完了嗎？）

② 在That's it一句中，表語it意為“問題之所在，關鍵之所在”，全句意為“對了，正是那個”，相當于That's right. 或That's the point.

That's it. He doesn't study as hard as others. 問題就在這里，他學習不如別人努力。

“Is this the best way to do it？” “That's it.” “這是做那件事的最好方法嗎？”“正是?！?

③ That's that一句中的that指上文剛提到的事，應譯為“就是這樣，就是這回事”。

He left without saying anything and that's that. 他沒有說什么就離開了，就是這樣。

提示

That's right一句中的that指對方說過的話，應譯為“你的話是對的?！盰ou are right一句中的you指具體的“人”，應譯為“你是對的。”指“你的做法、想法或態(tài)度”是對的。

You are right in telling the truth. 你說出了這事的真相是對的。

④ Is this it中的it是特指某個物件，意為“這是它嗎？”

“Where is my ruler？” “Is this it？”“我的尺子在哪里？”“是這把嗎？”（it等于your ruler）

“Where is the dictionary？” “Is this it？”“詞典在哪里？”“是這本嗎？”（it等于the dictionary）
