问题描述：
at last the man had no choice but ( )the compuer from the office 为什么but后面要用to admit doing
答
因为句型是：have no choice but do 别无选择只能...
答
have no choice but to do
can do nothing but do
都是些固定搭配
答
首先，have no choice but to do 是固定搭配，意思是“除了。。。别无选择”；admit doing 则是固定短语
答
双语结构
答
have no choice but to do sth 别无选择只能做某事,一个固定的搭配.
当but之前有实义动词do 的各种形式时,but 之后可以省略to
I could do nothing but wait.
