3 分词：
现在分词主动进行,过去分词被动状态
现在分词的形式:
1)一般式: Do you see the man talking to the dean（主任）? (与谓语动词同步发生)
2)完成形式：Not having made adequate preparations, they failed. (发生谓语动词之前)
3)完成被动形式：Having been adapted, the script seems perfect.( 发生谓语动词之前且表示被动)
过去分词
1) 过去分词表示被动：Fight no battle unprepared.
2)过去分词的进行形式：You'll find the topic being discussed everywhere. (强调正在被做)
这三种非谓语动词，都可以构成复合结构，非谓语动词所修饰的成分是这些非谓语动词的逻辑主语。他们之间的一致关系--主动还是被动，往往就是考点。独立主格结构中，要注意的是分词与他前面的逻辑主语之间的主动被动的关系。
二：虚拟语气和情态动词
情态动词的基本用法及其区别
最近几年高考试题中常常借助语境来考查情态动词的基本用法及其区别，因此在平时学习时准确理解和掌握情态动词的基本用法十分重要。情态动词的用法复杂多变，在高考试题中，命题者常常利用语境和句子之间意义上的细微差别来考查学生对情态动词的理解和掌握。对于情态动词，除了要求考生能够准确掌握它们的基本用法外，还要充分利用高考试题所设置的语境来分析句子之间所体现的特殊关系。下面就近几年来高考试题中出现的情态动词的考点进行归纳分析，以便同学们复习掌握。
一、用"情态动词＋have ＋done"结构表示对过去动作的推测，高考试题中常用过去时态或过去的时间状语给以暗示。情态动词的这一用法可以用 "对立统一"来概括。
1．当试题的前句和后句在动作和意义上相互补充说明，且整个句意在动作和时间上是一个整体时，我们可用"统一"关系来解决这样的试题。常见的结构有：
must have done：
表示对过去动作的肯定推测，常译作"一定做了……"，只能用于肯定句中。其否定形式为can't／couldn't have done?
疑问式为Can／Could...have done﹖。
could ／might have done：表示对过去发生的动作的可能性推测，常译作"可能做了……"。如：
1) My sister met him at the Grand Theater yesterday afternoon, so he
＿＿＿＿＿ your lecture． ?(上海 2000)
A． couldn't have attended
B． needn't have attended
C． mustn't have attended
D． shouldn't have attended
本题选A。
2) Jack ＿＿＿＿ yet, otherwise he would have telephoned me． (上海'97)
A． mustn't have arrived
B． shouldn't have arrived
C． can't have arrived
