Question

Johnny,you ________ play with the knife,you ________ hurt yourself.
A.won't,can't
B.mustn't,may
C.shouldn't,must
D.can't,shouldn't

Answer 1

答案B
考查mustn't表示“禁止”“绝对不可”的用法以及may表示“可能”的用法.
情态动词must意为“应当”“必须”.
mustn't意为“不应该”“不许可”“禁止”.play with the knife/the fire等意为“以……自娱”“拿……玩”,显然这是危险的,是不许可的,这样做可能会有危险.因此正确答案为B.
