The missing boys were last _____(play) near the park?

问题描述:

The missing boys were last _____(play) near the park?
to play和 playing填哪个比较好?
应该是The missing boys were last seen_____(play) near the park.

playing
see + sb do th
see+sb doing sth
这道题选play 和playing都行,选play的话,表示完成的意思,看到他们在那玩过
选playing的话,表示当时他们正在那玩
但不能选to play,表示看,听等感观的动词,后面要接动词原型做宾补,不能接不定式做宾补
