I watched him step off the pavement, cross the street, and disappear into the post office.
题目要求是用分词形式填空,上面是填完的句子.
为什么是step、cross、disappear,而不加ing呢?

watch sb do sth
这里的step cross disapper都是i watch
感观性的动作 see ,hear ,watch ,notice 后面可以接do ( 表示动作完成,做了某事,翻译成看见,听见,注意到某人做某事）
watch sb doing （表示看到,听到,注意到某人正在做某事）
我看到他走到人行道,穿过马路,消失在邮局
这过程是一系列的
你不可能翻译成
我看到他他正在走人行道,正在穿过马路,正消失在邮局吧.

再问：那如果把disappear换成run，是不是可以前两个原形，最后一个用running（可能现在还在跑）？
再答：不行的哦，这是一个一系列的过程。走到人行道，穿过马路，跑进邮局，这3个动作是一个一系列的过程，所以还是用run哦
