答案

应该是talk.
固定搭配 have nothing to do but/except +do
一般说来,介词后接动词应是动名词.但是介词but、except却比较特殊,后接动词时,可以接不定式,并且这个不定式可以带to也可以不带to：
1．当它前面的谓语含有实义动词do（可以是各种形式）时,其后的不定式通常不带to：
He did nothing but play chess yesterday．
2．当它前面的谓语没有实义动词do时,其后的不定式通常要带to：
I have no choice but to do it．
3．当其前含有实义动词do但不是用作谓语时,其后的不定式带不带to均可,但以不带to为多见：
There's nothing to do but（to）wait．
