情态助动词may表示可能性

may或might都表示“可能”、“也许”。通常既可以用may，也可以用might，不过might所表示的可能性要比may小，且当情况是虚拟的时只能用might而不能用may。

(1)may 表示现在或将来的可能性：may+动词原形：

The bread may be fresh.

面包可能是新鲜的。

He may be reading.

他可能正在看书。

I may go abroad.

我可能出国。

They may offer me a job.

他们也许会给我提供一份工作。

(2)may 也可表示过去的可能性，过去式为：may have(done):

He was late. He may have been busy.

他迟到了。他可能一直很忙。

I went out last night, and she may have been reading.

我昨天晚上出去了，她可能一直在看书。

It may have been right.

也可能是对的。

He may be working.他可能在工作。(对现在可能发生的事情的猜测)

He must be working.他肯定在工作。(对现在所发生事情有根据的推论)
