—Listen Is Miss Smith giving a speech in the class
—No,it _____ be her .She has gone to Hong Kong .
A may not B mustn't C can't D needn't
讨论的结果是选B还是选C有争议,

—Listen Is Miss Smith giving a speech in the class —No,it _____ be her .She has gone to Hong Kong .A may not B mustn't C can't D needn't讨论的结果是选B还是选C有争议,
C
我们老师讲过,mustn't是不允许,can't 是不会;不能
我敢肯定是C !

貌似我们考试的时候从来不允许用mustn't,如果需要用must的否定,一般会用needn't,而按这道题来说,应该选can't ,取”不可能”的意思

B mustn't 此题是表示猜测的题,一般猜测的都会用must!

我认为选C,表示否定的推测时,不用mustn't.而用can't.
mustn't 表示主观意愿。

c
肯定是c
根据句子意思推断说,Miss Smith是不会,不可能在做演讲的,
所以
a:不够肯定,含疑问,不符
b:不允许,,怎么可能不允许呢,,自己套进去想想
c: it is the right answer.
d:不需要,,不符合句意
