1、Review Of Tenses,动词的时态,不同时间发生的动作在英语中要用动词的不同的形式来对应表达。这种不同的变化形式就叫做时态。 英语中有16种时态，我们要掌握常见的8种时态。,1一般现在时 原形/第三人称单数 2一般过去时 过去式 3现在进行时 am/is/are+现在分词 4过去进行时 was/were+现在分词 5一般将来时 shall/will/be going to+动词原形 6过去将来时 would/was/were going to+动词原形 7现在完成时 have/has+过去分词 8过去完成时 had+过去分词,各种时态的动词结构,学好英语时态的四个关键: 1.牢记动词
2、四种形式变化;,2. 牢记动词各种时态的动词结构:,3. 牢记与各种时态搭配的时间状语和副词,4. 牢记各种时态使用的语言环境:,几种时态的区别,一般现在时与现在进行的用法区别 1. 一般现在时表示经常性或习惯性的动作；而现在进行时则表示现在或现阶段正在进行的动作。试比较： 1）What are you doing now?(暂时性的) 2） What do you do?（经常性的） 2.一些感官动词和心理状态动词不能用于进行时，但可用于一般现在时。这类动词常见的有：see, hear, smell, taste(品尝)，look（看起来），sound, feel, want, believ
3、e, think (认为),know, seem 等。例如： 1）The dish tastes delicious. 2)He wants to go at once.,一般现在时用于说明事实，一般不带有感情色彩；而现在进行时与always等连用，带有“羡慕”、“赞赏”、“讨厌”等感情色彩。试比较： She always lives happily. (陈述事实) She is always living happily.（羡慕） He is always telling a lie. (讨厌) 注意点一般现在时常与always, usually, often, sometimes, eve
4、ry day, in the morning等连用；而现在进行时常与now, today和表祈使语气look, listen等动词连用。试比较： 1) He usually gets up at 5 in the morning. 2) Look! A plane is flying in the sky.,一般过去时与过去进行时的用法区别 1. 一般过去时表示过去发生的动作或存在的状态，往往表示动作已完成；而过去进行时则表示过去某时或某段时间正进行的动作，动作不一定完成。试比较： 1) He wrote a letter last night. (信已写完) 2）He was writing
5、 a letter last night.（信不一定写完）。 2.一般过去时和过去进行时都可以表示过去某段时间内发生的动作或状态，但一般过去时用于说明事实，而过去进行时通常用来说明短暂性的动作，侧重于持续的时间。,试比较：1) It rained yesterday morning. (说明事实) 2)It was raining yesterday morning.(强调动作的持续性) 注意点过去进行时常与this time yesterday, at that time, at 7 oclock yesterday morning等表示时间点的状语连用。 试比较:1)He was maki
6、ng a model plane this time yesterday. 2)He made a model plane yesterday.,一般过去时与现在完成时的用法区别 一般过去时表示过去地动作或存在的状态，与现在无关；而现在完成时表示过去的动作对现在所造成的影响结果，或表示动作从过去某时持续到现在，与现在有联系。 试比较：1）I opened the window.(现在不一定开着) 2）Ive just opened the window.(现在仍然开着),注意点现在完成时的着眼点不是动作发生的时间，而是动作的结果，因此不能和表示确定的过去时间状语连用，但可与already, j
7、ust, yet, ever, never, these days, since,for,in the past few days 等连用；而一般过去时则着眼于动作发生的时间，因此若句中有表示过去的时间状语，如yesterday, a moment ago, last night, just now, before 1991等，就要用一般过去时，而不能用现在完成时。例如： Have you had your breakfast yet? Yes I had it at six.,一般过去时与过去完成时的用法区别 1.一般过去时表示过去发生的动作可存在的状态，而过去完成时则表示动作或存在的状态是
