Question

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。

Answer 2

选B
由“said” 可知，主句为一般过去时，则而后“that”引导的从句应为相对应的过去的某种时态。又因句尾的“the next day”意为“第二天”，则从句中的动词应为表将来的动词的过去式。即选 B 。
Won't = will not ,Wouldn't = would not .
Would是will的过去式。

Answer 3

wouldn't是过去将来时，won't是一般将来时

Answer 4

wouldn't=would not 而won't=will not
would 是will的过去式。知道了吧。

Answer 5

B.主句用过去时态时,宾语从句也要用过去时态,所以要选B.
won't=will not
wouldn't=would not
will 的过去式是would.

Answer 6

选b，won't=will not （一般将来时）
wouldn't=would not （过去将来时）
will 的过去式是would.
