(2)“may表达可能性

例:The news may be true.=Maybe [Perhaps] the news is true.

(或许这消息是真的。)

例:She may come to your birthday party tomorrow.

=Maybe [Perhaps] she'll come to your birthday party tomorrow.

(或许她明天会来参加你的生日宴会。)

解说 “may…”表达“可能性”时其意思等于“maybe”或“perhaps”,即“或许;也许”。“might…”也一样可用于表达现在或将来的可能性,只是语气较为宛转或对可能性觉得较为不确定。

He might have a hand in that case.=Maybe [Perhaps] he has a hand in that case.

(或许他涉及那个案子。)

表达可能性的“may/might…”通常不用于疑问句。可能性的疑问通常都使用“Can…?”或者“Do you think…?”,例如:

表达过去的可能性则使用“may/might have +p. p.”的句式,例如:He might have left for the United States.(他可能已到美国去了。)

(3)“may表达目的

例:He studies hard in order to get passed in the exam.

=He studies hard in order that he may get passed in the exam.

(为了要考试及格他努力在用功。)

例:He sold his house in order to pay his debt.

=He sold his house in order that he might pay his debt.

(为了要还债他把房子卖掉了。)

解说 如例所示表达目的时使用“to V…”比之使用“that +S+ may/might V…”较普通。“in order to V…/in order that +S+ may/might V…”是表达目的强调句式。

(4)“may表达祈愿句型 may you /he …+ V…

例:May you succeed.=I hope [wish] you'll succeed.(祝你成功。)

例:May God save our country.(愿上帝保佑我们的国家。)

(5)“May”的惯用表达句式

句型 may well +V…=there is good reason for +O +to V…

例:You may well say so.=There is good reason for you to say so.

(你很有理由这么说。——难怪你这么说。)

句型 may/might as well +V…=had better +V…

例:We may [might] as well start at once.=We had better start at once.

(我们最好立刻动身吧。)

解说 本句式常用于表达提议或劝告。
