一、情态动词的基本用法

◆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.

◆—Why didn’t you come to Simon’s party last night?
——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。
◆Would you please come here to help me?
请你来这儿帮我好吗？
(3)表示习惯或特性，以及自然的规律性。will用于现在，would用于过去。
