我一直分不清楚英语里有一个语法是 I have no choice but 还有I can`t do but do nothing but do 与have no choice but to do 与can't but do 关于cannot but do；can't help but to do;have no choice but to d i do have no choice but give up （改错) I have no choice but to do it. 关于I have no choice but to do I have no choice but ___ (wait). i have no choice,but to wait.当but 前面有do的时候,后面就省略to I regret ____(have)to do this,but I have no choice. I have no choice but to wait.I have nothing to do except sle How and what can I do I have been have no choice .I don't kn But I can't do
