一道英语改句子的题目!
The man must be sent to hospital at once.(改为反意疑问句)
The man must be sent to hospital at once,_______ ________?
我的答案是“needn't he”,但是答案上写的是“mustn't he”,请哪位大侠来讲讲原因吧·谢谢了!
★老师讲:must是必须,mustn't是不准
而 needn't 则是不需要诶!
不是一个意思的~好好讲一讲吧~
答
应该是mustn't,he.
must有两个意思:
1.当must是必须的意思时,反意疑问词用must
2.当must是一定的意思时,反意疑问词应为must后的be动词.
例:Your parents must be in the library,aren't they?
