被动语态He ---- play on the playground just now .A,was seen to B
4个回答

A.be seen to do被看到做某事.B结构不对.C是主动.D现在进行时不对.

关于B项:能跟不带to 的不定式作补足语的动词有:see,feel,hear,listen to,look at,watch,let,have,make,observe,notice.如:I saw him play in the street just now.而当这些词为被动式时,不定式要带to,如:He was seen to play in the street just now.
