336　have no choice but to do sth. 和do nothing but do sth.

① have no choice but to do sth.表示“沒(méi)有別的選擇，非做……不可，只好做某事”，but后的不定式要加to。

He had no choice but to leave. 他只能離開(kāi)。

I have no choice but to give up the plan. 我別無(wú)選擇，只能放棄這項(xiàng)計(jì)劃。

They had no choice but to sleep in the open. 他們只好在戶外過(guò)夜。

② 如果but前面有動(dòng)詞do/does/did，but后的不定式不帶to，結(jié)構(gòu)為：主語(yǔ)+do nothing but do sth.，意為“只做了什么，只能做什么”。

She can do nothing but wait. 她只能等待。（不用to wait）

There is nothing to do but walk about the town. 除了在城里到處走走，沒(méi)有其他事可做。

比較

He wanted nothing but to stay here. 除了留在這里他別無(wú)所求。

He had no choice but to stay here. 他只能留在這里。

He could do nothing but stay here. 他只能留在這里。
