May we leave the classroom now No,you-----.you --------to leave until the bell rings 的填空怎么
有四个选项 A.mustn't ; are allowed B.don't have to; are supposed C.needn't ; aren't allowed D.can't ; aren't allowed 请详解
答
选D.
回答must的提问时,要用can't或者don't have to回答.表示不能,或者不用一定.
既然是until,那就要想到not until句型哦.所以用aren‘t allowed to do.不被允许做某事.
