题目内容
2.You set out alone,or you get lost in the jungle.( )| A. | needn't,may | B. | mustn't,might | C. | cant,need | D. | mustn't,must |
分析 你不能单独出发,否则你会在丛林中迷路的.
解答 答案:B.
needn't不必;may可能;mustn't不可以;might,可能,may的过去式,表示的可能性不大;can't不可能,need需要;must一定,必须.根据You set out alone,or you get lost in the jungle,可知你不可以单独出发,否则你会在丛林中迷路的.从You set out alone,可知这里表示禁止做某事,应该用mustn't,再根据or you get lost in the jungle,可知否则你会在丛林中迷路的,这里表示可能性,用might表示.故选B.
