--- May we leave the classroom now ---- No,you can't.You ____ to leave until the bell rings.A.are allowed B.are supposed C.aren't allowed D.aren't supposed选什么呀 C和D有什么区别
选D,不是选C
be supposed to是应该的意思.
这句话的意思是在铃响前你们是不应该走的.
它表示的是某人应该做什么,不应该做什么.相当于should.
allow意思是允许,表示的是强制性的.有统治的意味.而什么时候该离开教室并非是统治的强制性,而应该是原则的约束性.所以应该选D.

选择C,C是表示你直到铃响了才被允许走
而be supposed to do表示被认为干什么事情
例如小红被认为是一个遵纪守法的好公民!
另外,not until 表示直到。。。才的意思答案给的是D那你的答案肯定有问题哦,有时候答案印刷的时候也会出现问题的,因为开始我也说了,be supposed to是表示被认为、设想做某事,在这里肯定不符合语境的哦...

每个人在汽车里都应该系安全带。
显然这里语气没那么好,题目中有强制的语气,选C...
