情态动词 may 和 might 可以用来表示“推测”，意思是“可能，也许”。译林版七下Unit 5《Amazing things》中出现了这样的用法。期中考试常以单选、填空和情景交际形式考查。本讲系统讲解 may 和 might 表推测的用法、区别以及否定形式，并通过分层练习确保学生熟练掌握。
一、may / might 表推测的基本用法
may 和 might 表示可能性，意为“可能，也许”，通常用于肯定句和否定句，一般不用于疑问句（疑问句表请求时可以用 May 但那是另一种用法）。may 表示的可能性比 might 稍大一些，might 语气更委婉、可能性更小。
注意：may 和 might 表推测时，只用于肯定句和否定句，一般不用于疑问句。疑问句询问可能性常用：D yu / Is it
二、may / might 表推测的句型结构
1. 肯定句： 主语 + may/might + 动词原形 + 其他.
例句：It may rain this afternn. (今天下午可能会下雨。)
例句：They might be in the library. (他们也许在图书馆。)
2. 否定句： 主语 + may nt / might nt + 动词原形 + 其他.
注意：may nt 表示“可能不”，might nt 表示“也许不”。
例句：He may nt knw the answer. (他可能不知道答案。)
例句：She might nt cme t the party. (她也许不来派对了。)
3. 一般疑问句： 表推测时很少用疑问句。若一定要问，常用：D yu
例如：D yu think he may be at hme? (你认为他可能在家吗？)
三、may / might 表推测与其它情态动词的区别
注意：may nt 表示“可能不”，而 can't 表示“不可能”，语气不同。例如：He may nt be at hme. (他可能不在家) / He can't be at hme. (他绝不可能在家)
四、may / might 表推测的语境运用
在以下情境中常用 may / might 表推测：
1. 对现在情况的推测：主语 + may/might + be + 表语/地点。
2. 对将来可能性的推测：主语 + may/might + 动词原形。
3. 对正在发生动作的推测：主语 + may/might + be ding.
例句：She may be sleeping nw. (她现在可能在睡觉。)
例句：They might be having dinner. (他们也许正在吃晚饭。)
五、may / might 的其他用法（与推测区分）
除了表推测，may 还可以表示“请求许可”（May I cme in?）和“祝愿”（May yu succeed!）。但期中考试重点考查表推测用法。注意区分：May 是请求句型，不表示推测。
