五、mustn"t可用于作出“不可能”的推测
旧观点：传统语法认为，表示对某事确有把握的推论或揣测，在肯定句中用must，在否定句中用can"t或couldn"t，不能用mustn"t。例如：
She can"t be a professor---she"s so young.
据此观点,下面的高考题只能选can"t/couldn"t表示“不可能”的推测（下划线者为答案）。
1.--There were already five people in the car but they managed to take me as well.
--It__________a comfortable journey.(NMET1995)
A. can"t be C.shouldn"t be C.mustn"t have been D.couldn"t have been
2.I didn"t see her in the meeting-room this morning.She________at the meeting.(上海1991)
A. mustn"t have spoken B.shouldn"t have spoken
C.needn"t have spoken D.couldn"t have spoken
3.Jack_________yet,otherwise he would have telephoned me.(上海1997)
