不得不的幾個用法

1. can't help but + 原型V

 

2. can't help + ving

 

3. have no choice but to + V

 

 

補充一:

I have no choice but to do it.

but to do it   為什麼這樣用?這種句型怎麼用?

 

這涉及but加動詞不定式的用法。

當不定式結構作 butexcept,besides) 等介詞的賓語,且 but(except,besides) 等詞前面的句中有實意動詞 do 時,該不定式結構中的 to 要省略,否則一般不省略。

例如:

1. We have no choice but to arrive late. 除了遲到以外,我們並無選擇。

2. We have no choice but to turn back. 沒辦法,我們只有回去。

3. You have no choice but to give up. 你別無選擇,只能投降。

 

4. At present I can do nothing but wait. 目前, 我只好等待。

5. He can do nothing but lie down and sleep. 他無事可做只好躺下睡覺。  

6. You can do nothing but let matter take their course. 你無能為力,只能聽其自然。

 

補充二:
