核心问题
（1）We missed the last bus so there was no choice other than to walk home. 我们错过了最后一班公交车，所以除了走回家别无选择。
(2) There was nothing to do other than wait. 除了等待,别无选择。
other than 之后的动词不定式是应当带 to, 还是应当不带 to?
词典解答
在一般情况下,other than 所连接的动词不定式是要带 to 的。但是,other than 之前有动词 do (does, did) 时,则 to 可以省略,也可以不省略:
-
He never speaks to me other than to ask for something. 他除了向我要东西，从不跟我说话。
-
There isn't anything to do other than to wait to see what happens. 除了等着看将发生什么事情之外没有别的办法。
