语法复习八：动词时态和语态（1）
一、动词的分类和形式：
动词是表示动作和状态的词。动词有时态、语态和语气3种形式的变化。
1、动词按其能否独立作谓语而分为："谓语动词"和"非谓语动词"两种
2、动词的4种基本形式：动词原形、过去式、过去分词和现在分词。
3、动词按其构成动词词组作用分为：实义动词、连系动词、情态动词和助动词。1）实义动词分为及物动词和不及物动词。还可分为持续性动词和瞬间动词；2）连系动词有两种：一种表特征或状态，另一种表状态变化过程。
4、五种不同的短语动词：1）"动词+介词"；2）"动词+副词"；3）"动词+副词+介词"；4）"动词+名词（或代词）+介词"；5）"be+形容词（包括相当于形容词的过去分词+介词"。
二、动词的时态：
1、一般现在时的用法：1）表示现在的习惯，经常发生的动作或存在的状态。2）表示主语的特征、性格和能力。3）表示客观事实或真理。4）表示按照计划安排好的将来行为。（只限于是go,come, leave, start, stop, be等开始或移动意义的词。）
2、一般过去时的用法：1）表示过去的动作或状态。2）叙述过去连续发生的事情。3）表示过去一段时间内经常发生的动作。
3、一般将来时的用法：1）表示将来的动作或状态。2）表示将来的经常动作。
4、现在进行时的用法：1）表示说话时正在进行的动作。2）表示现阶段正在进行的动作。（说话时动作不一定进行。）
5、过去进行进的用法：1）过去某一时刻或某一段时间内正在进行的动作。2）表示移动的动词：come, start, stay, leave, go等词的过去进行时可以表示过去的将来要发生的动作。3）was going to do可以表示在过去某一时间之后发生的动作。
6、现在完成时的用法：1）表示刚刚完成的动作，常与just连用。2）表示过去发生而持续到现在的动作或状态，甚至延续到将来。常与since, for连用，但for, since不能与终止性的动词连用。3）表示过去的动作对现在造成的影响或结果。
7、现在完成时与一般过去时的区别：1）现在完成时与现在有联系，它表示过去的动作对现在所产生的结果、影响。一般过去时通常表示在过去某一具体时间发生的动作，与现在没什么联系。2）现在完成时表示过去延续到现在的行为；一般过去时着重过去某一时刻的某一具体动作。
8、过去完成的用法：1）表示在过去某一或动作之前已经完成的动作。常与by, before等介词短语或一个状语从句或上下文暗示。2）表示由过去某一时间开始，一直延续到过去另一时间的动作，常和for（有时可省去）或since 构成的短语或since引导的从句连用。
9、过去将来时的用法：表示对于过去某一时刻而言将要发生的动作或存在的状态。
