1、教学流程:用将近一个小时的时间重点复习动词的时态,查缺补漏。剩下的时间处理学生14单元遗留的问题,包括单词、固定搭配以及小语法点。教学内容:主要以八种时态为主,让学生把以前没弄明白的时态弄清楚,分清楚它们的区别,熟练应用。教学目标:对时态完全掌握,前四个单元遗留的问题彻底解决。. 初中英语八种时态归纳 一、一般现在时:概念:经常、反复发生的动作或行为及现在的某种状况。时间状语:always, usually, often, sometimes, every week (day, year, month), once a week, on Sundays, etc.基本结构:be动词;行为动词否
2、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dont,如主语为第三人称单数,则用doesnt,同时还原行为动词。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。二、一般过去时: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。时间状语:ago, yesterday, the day before yesterday, last week(year, night, month), in 1989, just now, at the age of 5, one day, long long
3、 ago, once upon a time, etc.基本结构:be动词;行为动词否定形式:was/were+not;在行为动词前加didnt,同时还原行为动词。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。三、现在进行时:概念:表示现阶段或说话时正在进行的动作及行为。时间状语:now, at this time, these days, etc.基本结构:am/is/are+doing否定形式:am/is/are+not+doing.一般疑问句:把be动词放于句首。四、过去进行时: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。时间状
4、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。基本结构:was/were+doing否定形式:was/were + not + doing.一般疑问句:把was或were放于句首。五、现在完成时:概念:过去发生或已经完成的动作对现在造成的影响或结果,或从过去已经开始,持续到现在的动作或状态。时间状语:recently, lately, sincefor,in the past few years, etc.基本结构:have/has + done否定形式:have/has + not +d one.一般疑问句:h
5、ave或has。六、过去完成时: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”。时间状语:before, by the end of last year(term, month),etc.基本结构:had + done.否定形式:had + not + done.一般疑问句:had放于句首。七、一般将来时: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。时间状语:tomorrow, next day(week, month, year),soon, in a few minutes, by,the day after tomo
6、rrow, etc.基本结构:am/is/are/going to + do;will/shall + do.否定形式:was/were + not; 在行为动词前加didnt,同时还原行为动词。一般疑问句:be放于句首;will/shall提到句首。八、过去将来时:概念:立足于过去某一时刻,从过去看将来,常用于宾语从句中。时间状语:the next day(morning, year),the following month(week),etc.基本结构:was/were/going to + do;would/should + do.否定形式:was/were/not + going to
7、 + do;would/should + not + do.一般疑问句:was或were放于句首;would/should 提到句首。. 几种常見时态的相互轉换英语中的几种时态在一定情况下可以互相轉换,以下是几种常見的轉换形式:一、一般过去时与现在完成时的轉换在现在完成时中,延续性动词能与表示一段时间的状语連用,瞬间动词却不能。但是,可用別的表达方式:瞬间动词用于“一段时间 + ago”的一般过去时的句型中;瞬间动词可改成与之相对應的延续性动词及短语,与一段时间連用;瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中,表示“自从以来有时间”的意思,主句一般用it
8、is来代替It has been;瞬间动词用于“Some time has passed since + 一般过去时”的句型中。请看:A. He joined the League two years ago.B. He has been in the League for two years.C. It is two years since he joined the League.D. Two years has passed since he joined the League.二、一般现在时与现在进行时的轉换在一般现在时中,at加上名词表示“处于某种状态”,如at work(在工作),
9、 at school(上学、上课)等。此短语可与进行时态轉换。请看:Peter is at work, but Mike is at play.Peter is working, but Mike is playing.三、现在进行时与一般将来时的轉换在现在进行时态中go, come, leave, start, arrive等动词常与表示将来的时间状语連用表示将要发生的动作。如:I am coming, Mum! 意为“我就来,妈妈!”请看:The train is leaving soon.The train will leave soon.四、“be going to+动词原形”与“wi
10、ll(shall)+动词原形”结构的轉换“be going to+动词原形”、表示打算、计划要做的事;将来时“will(shall)+动词原形”结构在书面语中,当主语为第一人称时,常用助动词shall。在口语中,所有人称都可以用will。请看:We are going to visit the Great Wall next Sunday.We shall visit the Great Wall next Sunday中考英语动词时态专项训练一、用所给词的适当形式填空:1 He swimming in the river every day in summer.
