九上英语!He can play volleyball very well.So he -----

C
So I do的用法
该结构主要用于加强语气,其意为“的确如此、确实如此”,表示后者赞同前者的话或意见,只是进一步强调并重复前句所述的内容.前后句的主语指的是同一个人或物.该结构中的助动词 do 根据前文的情况也可换成 is,am,are,was,were,does,did,can,could 等.如：
—He has done a good job.他干得不错.
—So he has.他的确干得不错.
—He will speak at the meeting tomorrow.他明天将在会上发言.
—So he will.确实如此.
—He went to see his friend yesterday.他昨天去看朋友了.
—So he did.的确如此.
这句话也一样,
He can play volleyball very well.
So he can
