英语中如何辨别句子的时态
一般情况下看时间状语
一、一般现在时 表示一般状态、习惯动作、客观规律和永恒真理
二、现在进行时 表说话时或目前一段时间内正在进行的活动;或表感情色彩,加强浯气。
三、现在完成时 表目前已完成的动作,强调对现在的影响。时间是算到你说话的时候为止,而且现在完成时有一些标志性的时间状语: 1.for+时间段;I have learned English for ten years. 2.常见的副词:lately;recently, just,up to now, till now, so far, these days, in the past few years/months/weeks/days 3.注意:for+时间段;since+时间点 They have lived in Beijing for five years. They have lived in Beijing since l995. 4.This is the first time that I have watched stars through a telescope. 第几次做某事,后面跟现在完成时。
四、一般过去时 表在过去某个特定时间发生且完成的动作,或过去习惯性动作,不强调对现在的影响,只说明过去。常跟明确的过去时间连用,如:yesterday;last week;in 1945,at that time;once;during the war;before;a few days ago;when,注意: 1、used to+动词原形,表过去经常但现在已不再维持的习惯动作。 He used to smoke. 2、be/become/get used to+动名词doing,表习惯于 He has got used to getting up early. He used to smoke a lot. 3、They have lived in Beijing for five years. 用现在完成时表示到目前是5年。 He lived in Japan for five years as a middle-school student. 用一般过去时则表示这个时间段和现在无关,只表示他过去在日本住了5年。
五、过去进行时 表示过去某个时间点或某段时间内正在发生的动作。 The boy was doing his homework when his father came back from work. He was taking a leisurely walk by the lake when he heard someone shouted for help. 六、过去完成时 表示过去某个时间之前已经完成的动作,句中有明显的参照动作或时间,before,after,by,up till There had been 25 parks in our city up till 2000. By the end of last term we had finished the book. They finished earlier than we had expected.
一 ,一般现在时的用法
1) 经常性或习惯性的动作,常与表示频度的时间状语连用。时间状语: every…, sometimes, at…, on Sunday。例如: I leave home for school at 7 every morning.
2) 客观真理,客观存在,科学事实。例如: The earth moves around the sun. 3 现在时刻的状态、能力、性格、个性。例如:I don't want so much. 我不要那么多。 Ann writes good English but does not speak well. 安英语写得不错,讲的可不行。
二, 一般过去时的用法
1)在确定的过去时间里所发生的动作或存在的状态。例如:时间状语有:yesterday, last week, an hour ago, the other day, in 1982等。例如: Where did you go just now?
2)表示在过去一段时间内,经常性或习惯性的动作。例如: When I was a child, I often played football in the street. 我是个孩子的时候,常在马路上踢足球。
三, 一般将来时 将来某一时刻将要发生的动作或状态I will come to see you tomorrow.
2)be going to do a. 主语的意图,即将做某事。例如:What are you going to do tomorrow? b. 计划,安排要发生的事。例如:The play is going to be produced next month。这出戏下月开播。c. 有迹象要发生的事。例如:Look at the dark clouds, there is going to be a storm. 看那乌云,快要下雨了。
3)be +不定式表将来,按计划或正式安排将发生的事。 We are to discuss the report next Saturday.
4)be about to do,意为马上做某事。例如: He is about to leave for Beijing. 注意:be about to do 不能与tomorrow, next week 等表示明确将来时的时间状语连用。
四 , 现在进行时现在进行时的基本用法: a. 表示现在(指说话人说话时)正在发生的事情。We are waiting for you. b. 习惯进行:表示长期的或重复性的动作, Mr. Green is writing another novel. 他在写另一部小说。(说话时并未在写,只处于写作的状态。) c. 表示渐变,这样的动词有:get, grow, become, turn, run, go, begin等。 It's getting warmer and warmer. 天越来越热了。 d. 与always, constantly, forever 等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩。You are always changing your mind. 你老是改变主意
五, 过去进行时
1)概念:表示过去某时正在进行的状态或动作。
2)常用的时间状语有this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while等。My brother fell while he was riding his bicycle and hurt himself. It was raining when they left the station.

2)常用的时间状语有soon, tomorrow, this evening,on Sunday, by this time,tomorrow, in two days, tomorrow evening等。例如:By this time tomorrow, I'll be lying on the beach.
七,在完成时 用来表示之前已发生或完成的动作或状态,其结果的影响现在还存在;也可表示持续到现在的动作或状态。其构成:have(has)+过去分词。
现在完成时例句Tom has finished his home work and he is watching TV now.(完成作业是过去的动作,但对现在造成了影响,用现在完成时)He has lived here for 5 years.(居住的动作从5年前一直持续到现在,用现在完成时。)现在完成时时间状语:ever,many times,recently,just,yet,already,before等。八 过去完成时结构 主语+had+过去分词 表示过去某一动作或时刻之前完成的动作或状态,即过去的过去。时间状语:by,before,until,when例句 When Jack arrived,he learned Mary had been away for almost an hour.(Mary 离开在Jack到达这个过去的动作之前发生,用过去完成时)
-----------
引导时间状语的句子通常附有时间名词,若无,必须经过上下文的推敲来得知是否改用时间状语,其引导词通常有when,while,before,after等。时间状语只是属于复合句的一种,不属于动词时态。但往往动词时态会运用于时间状语中。动词时态一共有16中,每一种都有可能用于时间状语 PS:Good LUck!祝你好运!

看表示时间的标志词如:usaually
annualy..出现这些都是一般现在时,还有关注表示频率的词:如often..最重要的是看动词形态,因为有主语的话都有动作产生
