一道高中英语试题
What the old man ( )have a great effect on him.
A does B does do C does does D do does

the old man 是单数,所以第一个是does
what the old man也作第三人称单数,所以也是does
感觉这个时态全有问题,怎么不用过去时

B 后面一个do 是have的强调

C
前一个does:What the old man does是主语从句,正装过来相当于the old man does what
后一个does:表示强调,(What the old man does)dose have a great effect on him

c
what the old man does what引导主语从句
does 起强调作用
此句也可以写成
What the old man does has a great effect on him
