Question

1.Michael ( ) be a policeman,for he's much too short
A.needn't B.can't C.shouldn't D.won't
2.I thought you ( ) be hungry,so I have brought you some cakes
A.may B.might C.can D.could

Answer 1

1 B.can't 是must作为推测是的否定形式,意思是一定不.根据句意：麦克不可能是警察,他太矮了.A不需要；C不应该和D不会都不合题意.
2 B.前面用的是过去式thought,所以后面应该用might或could.很明显,空处应该填的是表示可能含义的词.can和could表示可能是一般用于否定和疑问句,这是一个肯定句,所以选B.
