3) may /might 推测性用法 可能
He may be right.
may/might 表示 可能性
may或might都表示“可能”、“也许”，
不过might所表示的可能性要比may小。
1）现在或将来的可能性：may/might+动词原形：

3.表建议（可和as well 连用）

2)表现在的“可能”，其可能性要比may小。

电熨斗会有危险，它可能电着人。
3)may (might) + have +done 表示对过去发生行为的推测，含有“想必”、“也许是”的意思。

总结：情态动词表示推测
根据推测可能性的大小，以此为：
must(一定)>should(很可能) > could(可能) >may(可能) >might(或许) >can’t(不可能)

回答
祈使句的回答
祈使句的动作通常表示将来发生的动作，
所以回答时一般用will或won’t.
回答具有否定意义的祈使句时，要注意两点：
一是：形式一致，即Yes与will保持一致，No与won’t保持一致；
