一道初中英语题,won't与wouldn't 区别
he said that he ( )free until the next day .
A.can't be B. wouldn't be C. won't be D. hasn't been
选什么,为什么,
请说说won't与wouldn't 区别

Answer 1

won't 是will not 的缩写表示“将来不”； wouldn't是will not 的过去式,表示过去所说的“将来不”.
said是过去时,后面的宾语从句要与其保持时态的一致 所以应用过去时,但因为表示第二天所以应有将来的语气在里面,故选择wouldn't.
另外 can't be 在这里不太符合语意； 而hasn't表示已经发生的动作,这和对明天的猜测不符.
