might as well 和 may as well，都表建议，但还是有区别的

一、在做一件事没有更好的选择又没有理由不做的时候，我们可以使用  might as well 和 may as well 来表达最容易或是最符合逻辑的行动。它们都是非正式的表建议的说法，might as well 更为普遍。例如：

You might as well tell them the truth.

你不妨告诉他们真相。

We may as well begin now.

我们不妨现在就开始。

You might as well get a taxi from the station. It’ll be quicker than me coming in to get you.

你不妨从车站叫辆出租车。这比我来接你块。

A: Should we start now?

我们现在就开始吗？

B:Might as well. （非正式）

也可以。

A: What time does the film finish?

电影什么时候结束？

B: I think it’s ten o’clock.

我想是十点钟了。

A: Uh-huh. We may as well eat in town before it, then.

啊哈。那么，我们还是先在城里吃饭吧。

The party was so dull that I might just as well have stayed home.

聚会太无聊了，我还不如呆在家里。

二、当要加强语气时，可以在 might 和 may 后加 just，例如：

Well, I think if it’s a choice between a job and a place at college, you may just as well take the job. At least you’ll earn some money.

好吧，我想如果是在工作和上大学之间做出选择的话，你不妨接受这份工作。至少你能挣点钱。

We don’t know anyone here and they’re discussing stuff that doesn’t concern us. We might just as well leave.

我们不认识这里的任何人，他们在讨论与我们无关的事情。我们还是走吧。

三、在表达额外的可能性时，might as well 和 might also，may as well 和 may also 是不一样的意思，例如：

在你去远足之前，给自己买双好靴子。你可能还需要买厚袜子。

正：Before you go hiking, buy yourself a good pair of boots. You may also need to buy thick walking socks.

误：Before you go hiking, buy yourself a good pair of boots. You may as well need to buy thick walking socks.

解析：本句强调除了要买一双靴子，可能还需要买一双厚的袜子，虽然在表示建议，但不体现没有其他的选择了。
