Question

–I think Mr Zhang may be in his office.
--No, he         be there. I saw him         just now.
A. needn’t, left                 B. mustn’t, leaving
C. can’t, leave                  C. shouldn’t, leave

Answer 1

D

试题分析：句意：——我认为张先生可能在他的办公室。——不，他不可能在那里。我刚才看见他离开了。needn’t不必；mustn’t禁止；can’t不可能；shouldn’t不应该。根据 I saw him         just now.可知izheshi有把握的推测，故第一空用情态动词can’t。see sb. do sth.看见某人做了某事，故第二空用leave。故选D。
