英语中，may well, may just as well 和 may as well as 很相似，但是它们表达的意思并不相同，今天我们一起来学习一下它们的用法区别。

1．May well：这个短语的意思是“不妨；倒不如”。这个短语也可以为may as well.

例句1：We may as well go swimming this afternoon.

我们今天下午倒不如去游泳。

例句2：We may well think so.

我们不妨这样想。

例句3：You may as well tell the truth.

你还是实话实说为好。

2. may just as well：这个短语的意思是“不也一样吗；合情合理”。

例句4：You may just as well give the birthday gift to Tom yourself.

你自己亲自把生日礼物给汤姆不是更好吗！

3. may as well …as：这个短语的意思是“做…，还不如…算了”。

例句5：You may as well advise me to give up my life as my reading.

注意，以上三种情况的may均可以用might来代替，表达的与may相同的意思。
