-- I ___ Tom for three days.Is he ill?-- I'm afraid so.The doctor said he needed ____ .
A.haven' t seen; an operation
B.haven't seen; to be operated
A
但解析应如下：
在此句needed可以看出,need是做情态动词.所以,被动语态是needed be done
答案的确应选A,need可用作情态动词,也可用作实义动词,本句中need为实义动词,其后可接名词也可接不定式.但如果选B的话,需要在operated后面接一介词on才行,因为operate不能直接人,表示给某人做手术时要用operate on sb.故被动语态应为he needed to be operated on.
