◆You may choose whatever you like.

你喜欢什么就选择什么。

◆—May I stay in the room for a while?

——我可以在这个房间待一会儿吗？

—Yes, you may./No, you mustn’t.

——是的，可以。/不，不可以。

(2)表示把握不大的推测，意为“有可能”。用于肯定句或否定句中；might语气更加不肯定。

◆The traffic is very heavy these days.I may arrive a bit late, so could you save me a place?

这些天交通很拥挤，我可能会来晚一点，请你帮我留个位置好吗？

◆She might go out because the phone was ringing all the time.

——你昨晚为什么没有来参加西蒙的聚会？

—I wanted to, but my mom simply would not let me go out so late at night.

——我想去，但是我妈妈不愿意让我晚上这么晚出去。

(2)表示征求意见或提出请求。would的语气更加委婉。
