时态是英语学习中一个至关重要的内容,广大初中学生在实际运用时,往往对时态总是倍感棘手,下面我们就归纳复习一下這几种时态。
概念:经常、反复发生的动作或行为及现在的某种状况。
always, usually, often, sometimes, every week (day, year, month…), once a week, on Sundays, etc.
②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。
②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。
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 ago, once upon a time, etc.
②用助动词do的过去式did 提问,同时还原行为动词。
时间状语:now, at this time, these days, etc.
否定形式:am/is/are+not+doing.
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。
否定形式:was/were + not + doing.
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, since…for…,in the past few years, etc.
否定形式:have/has + not +done.
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.
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 tomorrow, etc.
①am/is/are/going to + do;
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.
①was/were/not + going to + do;
②would/should + not + do.
英语中的几种时态在一定情况下可以互相转换,以下是几种常见的转换形式:
在现在完成时中,延续性动词能与表示一段时间的状语连用,瞬间动词却不能。但是,可用別的表达方式:
①瞬间动词用于"一段时间 + ago"的一般过去时的句型中;
②瞬间动词可改成与之相对应的延续性动词及短语,与一段时间连用;
③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 is来代替It has been;
④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.
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), at school(上学、上课)等。此短语可与进行时态转换。请看:
Peter is at work, but Mike is at play.
Peter is working, but Mike is playing.
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连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.
4、"be going to+动词原形"与"will(shall)+动词原形"
"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.
