He _____ see me in the street yesterday.
问题描述：
He _____ see me in the street yesterday.
a.seemed not to b.pretended not to
选B
A里的seem这种用法是后面跟不定式,相当于He didn't seem to see.语法是正确的应该,可为什么不能选呢?
答
不能选A,因为如果要用seem to do sth.的结构,就必须这么说：He seemed not to have seen me.而不是;He seemed not to see me.在seem后表示过去的动作,要用to have done sth.的结构.
