情态动词和虚拟语气
情态动词与虚拟语气有千丝万缕的联系， 它们往往放在一起考查。在近年高考试题中， 对情态动词的考查几乎每年都有。纵观近几年 的高考试题可以看出，高考对情态动词的考查 热点主要包括： 1. 准确把握情态动词表允许、推测、判断 等用法。 2. 准确把握情态动词在虚拟语气结构中的 使用。 3. wish, as if/though, if only, would rather ＋从句，It's time＋从句等句型中的虚拟语气。
表示许可: may / might, can / could •might, could 比较委婉, 一般多用于 疑问句。
* can, may 表达的语言比较随便。
在以could, might 表示征询对方意见或 表示请求时, 回答应相应使用can, may。
