(单词翻译:双击或拖选)

A 用于推测过去的行动:

He may/might have gone.相当于:

It is possible that he went/has gone./Perhaps he went/has gone.

当时他可能去了。

如第132节D所述,如果主句的动词是过去时,就必须用might:

He said/thought that she might have missed the plane.

他说/想她可能已经误了那班飞机。

如不确定性已然消失,必须用 might而不用 may:

He came home alone.You shouldn't have let him do that;he might have got lost.

他独自回家了。你本不应当让他那么做的,他可能会迷路的。(但他并未迷路。)

在下一句中也是这样:

You shouldn't have drunk1 the wine;it may/might have been drugged.

你本不应喝那酒的,里边可能放了药。

it may have been drugged通常表示还不能确定酒里是否放了迷药。

it might have been drugged也可具有与上述相同的含义,但也可能意指现在知道酒里没有迷药。

在叙述最终并未得到检验的事情时用 might而不用 may:

Perhaps we should have taken the other road.It might have been quick- er.

也许我们本应当走另一条路。那样可能更快些。

It's a good thing you didn't lend him the money.You might never have got it back.

你没借给他钱倒是好事。如果你借给了他,就可能永远也要不回来了。

上述这类例句同条件句的第三种类型非常相似:

If we had taken the other road we might have arrived earlier.

如果我们当时走了另一条路,就可能到得早一些。

B may/might可用于条件句中以代替will/would,表示一种可能的而不是肯定无疑的结果:

If he sees you he will stop.

如果他看见你,他就会停下来。(确定的)

If he sees you he may stop.

如果他看见你,他可能停下来。(可能的)

同样, may/might也可用于下列句子当中:

If you poured hot water into it,it might crack2.

你如果往它里面倒进热水的话,它就可能裂开。

If you had left it there someone might have stolen it.

要是你当时把那东西落在那里,就可能有人把它偷走。(参见第223节B。)
