35.他们明天可能乘火车去那里,但是我不能确定。

37.You should read some interesting books to reduce stress. (改为委婉建议)
You ________ ________ some interesting books to reduce stress.
【答案】 could/might read

That ________ ________ Lily. She has to stay at home.
【答案】 couldn’t be
【详解】句意:那不可能是莉莉。她得待在家里呢。“can’t be Lily”表示有把握的否定推测,意为“不可能是莉莉”,可用情态动词couldn’t后接动词原形be替换,couldn’t也表示否定推测,只是语气较can’t缓和。
39.He must be a graduate from a famous college. (改为否定句)
He ________ a graduate from a famous college.
【答案】can’t be/ cannot be
【详解】句意:他一定是一名来自著名大学的毕业生。must表肯定推测时,否定推测用can’t,意为“不可能”,后接动词原形be。故填can’t be/cannot be。
