所谓英语语法中的时态,也就是针对不同的时间,在语法上(一般来说是动词)作出的一些调整。这些调整时非常有必要的,否则,你将不知道对方谈的事情是什么时候发生的,与现在的关系又是怎么样的。
我给你说几个常用的
1.一般现在时 谓语动词为原型
这是用于经常发生的时态;也表示客观存在、客观真理。
也有用一般现在时表示将来的情况,但这并不多。
2.一般过去时 谓语动词为过去式
表示动作发生在过去,但对现在无影响(这半句主要是和现在完成时进行区别)
3.一般将来时 谓语动词前加will即可
表示动作将要发生
4.一般过去将来时 把一般将来时中的will改为would即可,其他无变化
表示从过去的某一时间来看将来要发生的动作或存在的状态。一般过去将来时的出发点是过去,即从过去某一时刻看以后要发生的动作或状态。
5.现在进行时 谓语动词加ing
表示动作在此时此刻正在进行,正在发生.
6.过去进行时 把现在进行时中的Be动词改用was(主语为单数)/were(主语为复数)就行了
表示动作在过去某个时刻正在进行,正在发生.
7.现在完成时 这是非常非常常用,并且重要的时态。
(1)表示动作发生在过去,但对现在有 影响。 (2)强调动作对现在的影响。
8.过去完成时 把现在完成时中,相应的has/have改为had即可,其他不变
表示动作发生在过去的过去
额 不知道是否能让你明白了。语法学习是要一定的记忆做基础的,加油!本回答被提问者采纳

动词时态表(以 write为例)
一般时态 进行时态 完成时态
现在 Write/writes Am/is/are writing have/has written
过去 wrote was/were writing had written
将来 shall/will write Shall/will/be writing shall/will have written
过去将来 should/would write
e.g.:
He often writes a letter to his father.
I often write a letter to my mother.
He is writing a letter to his mother now.
I am writing a letter to my mother now.
He has already written a letter to his mother.
I have already written a letter to my mother.
He wrote a letter to his mother yesterday.
He was writing a letter to his mother when I saw him.
He had written a letter to his mother before I saw him.
He will write a letter to his mother this afternoon.
I will/shall write a letter to my mother this afternoon.
He will be writing a letter to his mother at4 tomorrow afternoon.
I shall /will be writing a letter to my mother at 4 tomorrow afternoon.
He will have written a letter to his mother by the end of next week.
I will have written a letter to my mother by the end of next week.
He said that he would write a letter to his mother the next day.
简单一点说,必须掌握的就是八种基本时态。
一般现在时
1.概念:经常、反复发生的动作或行为及现在的某种状况。 2.时间状语: always, usually, often, sometimes, every week (day, year, month…), once a week, on Sundays, 3.基本结构:动词 原形 (如主语为第三人称单数,动词上要改为第三人称单数形式) 4.否定形式:am/is/are+not;此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词。 5.一般疑问句:把be动词放于句首;用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。
现在进行时
1.概念:表示现阶段或说话时正在进行的动作及行为。 2.时间状语:now, at this time, days, etc. look . listen 3.基本结构:be+doing 4.否定形式:be+not+doing. 5.一般疑问句:把be动词放于句首。 现在完成时
(1) 现在完成时表示从过去持续到现在的动作或状态 现在完成时的这种用法通常与由since或for引导的时间状语连用。如: The old man have lived here for more than twenty years. 老人已在此住了20多年了。 (2) 现在完成时表示过去发生的对现在有影响的动作 [1] 现在完成时的这种用法有时不带时间状语,有时可以和already, before, ever, just, lately, never, once, recently, yet等一些所指时间不具体的时间状语连用。如: Have you ever been to Australia? 你去过澳大利亚吗? 现在完成进行时
1.概念:表示从过去某一时间开始一直延续到现在的动作。这一动作可能刚刚开始,也可能仍在继续,并可能延续到将来。 2.基本结构:have/has +been+doing 3.时间状语:since+时间点,for+时间段等。 4.例子:I have been sitting here for an hour. The chirdren have been watching TV since six o'clock. (1) 现在完成进行时表示从过去一直持续到现在的动作或刚刚结束的动作 一般过去时
1.概念:过去某个时间里发生的动作或状态;过去习惯性、经常性的动作、行为。 2.时间状语:ago, yesterday, the day before yesterday, last week,last(year, night, month…), in 1989, just now, at the age of 5, one day, long long ago, once upon a time, etc. 3.基本结构:be动词;行为动词 的过去式 4.否定形式:was/were+not;在行为动词前加didn't,同时还原行为动词。 过去进行时
1.概念:表示过去某段时间或某一时刻正在发生或进行的行为或动作。 2.时间状语:at this time yesterday, at that time或以when引导的谓语动词是一般过去时的时间状语等。 3.基本结构 s+was/were+doing 4.否定形式:s+was/were + not + doing. 5.一般疑问句:把was或were放于句首。(第一个字母大写) 5.一般疑问句:was或were放于句首;用助动词do的过去式did 提问,同时还原行为动词。
过去完成时
1.概念:以过去某个时间为标准,在此以前发生的动作或行为,或在过去某动作之前完成的行为,即“过去的过去”。 2.时间状语:before, by the end of last year(term, month…),etc. 3.基本结构:had + done. 4.否定形式:had + not + done. 5.一般疑问句:had放于句首。
一般将来时
1.概念:表示将要发生的动作或存在的状态及打算、计划或准备做某事。 2.时间状语:tomorrow, next day(week, month, year…),soon, in a few minutes, by…,the day after tomorrow, etc. 3.基本结构:主语+am/is/are+going to + do;will/shall + do. 4.否定形式:am/is/are not going to do ;will/shall not do。 5.一般疑问句:be放于句首;will/shall提到句首。 过去将来时
(1) 过去将来时表示过去某时之后将出现的情况,通常用于宾语从句中。如: I thought he would come. 我以为他会来。 Jenny never imagined that she would become a doctor. 詹妮从没想到自己会当医生。 (2) 表示从过去某时看将要发生的事情。如: The old lady was fifty-eight then. In two years she would be sixty. 老太太当时五十八岁,再过两年就六十了。 I didn’t think they would have any objection to it. 我想他们不会有什么反对意见。 (3) 表示过去习惯性动作(不管什么人称都用would)。如: Whenever he had time, Harris would go to see his grandmother. 哈里斯一有时间就去看他奶奶。 Joanna would go for a walk after
