Question

这两题有什么区别?
1.Tom did nothing else but___back all his friends owed him.( )
A.to take B.took C.taking D.take
2.Has he any other choice but____as you tell him to?( )
A.to do B.do C.doing D.did
请说明一下怎么区别but后+do还是+to do,最好以这两道题作为例子,

Answer 1

..but to do ..,在前面的动词是do和它的变形是将to省略
口诀为：前有do,后省to.（我们老师讲的）
