问题描述：

请指教:单选(1070)-Tom,you must do as you're told to
-Tom,you must do as you're told to
-Oh,I must,____
A.must
B.should
C.needn't
D.mustn't
可是答案给的是

答

我咋觉得C,D都行

答

也许是I must表示此人对此不满,即原句为否定,所以反意疑问句要用must I

答

反意疑问句中大多数都是句末将助动词否定
这里AB都不是反意疑问句形式了
所以只有C D
但must的否定形式mustn't意思为“禁止”
所以应该选C needn't 意思是“哦,我必须,一定要吗?”
must的同义否定形式是needn't

答

选C
