为何like后可以用动词原形

We'd actually do things together, like drink wine and smoke cigarettes and talk all night.

这是大家一篇课文里的句子 这里like不是介词吗 为何后面列举时都是动词原形而不是用ing呢

We'd actually do things together, like drink wine and smoke cigarettes and talk all night.

like 是介词没错，表示列举。后面的动词原形其实是不定式省去了 to。省去 to 是什么原因由于前面 do用了原形。不定式用原形是针对do，与 do 对等。不定式也可以针对 things, 与 things 对等，则用动名词：

We'd actually do things together, like drinking wine and smoking cigarettes and talking all night.
