时态讲解及其练习题剖析(DOC 10页).doc

1、unit3 时态英语动词的时态，按动作发生的先后顺序，可分为现在、过去、将来和过去将来四个时间；也就是所谓的“时”。按动作发生的状态，又可分为一般式、进行式、完成式和完成进行式四种类型，也就是所谓的“态”。由时和态结合，便形成下列十六种时态：1.一般现在时 2.一般过去时 3.一般将来时 4.一般过去将来时 5.现在进行时 6.过去进行时 7.将来进行时 8.过去将来进行时 9.现在完成时 10.过去完成时 11.将来完成时 12.过去将来完成时 13.现在完成进行时 14.过去完成进行时 15.将来完成进行时 16.过去将来完成进行时 常考时态过去时一般过去时过去进行时过去完成时现在时一般现

6、r, father.一：高考特点 动词的时态和语态是历年高考英语测试的重中之重，每年试题一般不低于两道。命题思路有三种：1.是直接给出标志性时间状语，考生能根据其作出选择；2.是给出时间状语，但所给时间状语有较强的干扰性，考生不能直接根据时间状语作出选择，而需要结合语境进行判断；3.是没有任何时间状语，需要借助于上下文语境，才能作出正确判断。 在历年有关被动语态的考题中，共涉及了七种基本时态的被动语态，其中以现在完成时、一般现在时、一般过去时和现在进行时考得最多。被动语态由“助动词be+过去分词”构成，时态通过be动词表现出来。二：应考策略1.高考命题中往往不会涉及单一的时态，而是更多地侧重于

7、时态的交叉使用和时态干扰。2. 考生答题时要认真研读题干，寻找尽可能多的“时间参照信息”，尤其是句中其他动词的时态，以及修饰动词的状语信息等等。关于被动语态题，做题时应首先根据主语与谓语的关系确定是否是被动关系，然后再根据有关时间信息确定用哪种时态。3. 还要注意的是不及物动词是不能用于被动语态当中。三 ：时态具体讲解1. 一般现在时（1）考查其基本概念：一般现在时表示一个习惯性、经常性的动作。常与表示习惯的副词always, every time, now and then, occasionally, often, seldom, sometimes, usually 等连用。但近几年，对

11、要表示过去某时发生的动作或情况，常常与表示过去的时间状语连用，如yesterday,last month,in 2005,a few minutes ago,before liberation,just now,last week等。句中没有明确的时间状语，那么在上下文中就一定有表明过去的时间状语或可以体现“动作情况”的概念。一般过去时的主要用法：(1) 表示在过去时间里发生的动作或存在的状态。即学即练：Dinosaurs _ (die)about 65 million years ago.恐龙在约6 500万年前灭绝了。(2)表示过去经常或反复发生的动作。可以用“used to+动词原形”或
