— Listen! Helen is singing in the classroom.
—It _______ be Helen. She has gone to Shanghai.| A．mustn’t | B．may not | C．can’t | D．should |

答案
| C |
解析
试题分析：句意：--听！海伦正在教室里唱歌。--不可能是海伦。她已经去上海了。分析：mustn"t在英语中不能用于表示推测，但是可以表示“禁止/不允许”之意。如：You mustn"t smoke here. 在这里你不许抽烟。2. can"t/couldn"t表示推测时，意思是“不可能……”，语气非常坚决的否定推测。本句表示推测之意。故选C |
