1、Four short words sum up what has lifted most successful individuals above the crowd: a little bit more.-author-date英语语法基本基础知识时态英语语法基本基础知识时态英语的时态问题英语的时态可以分为： “时”(time) 和 “体”(aspect)（又称为态）。时是指动作发生的时间，体是指动作发生时的状态。时间与体就象是坐标里的横轴和纵轴，它们的结合交织出了瞬息万变的时空，也构成了英语动词的时态问题。时间分为：过去，现在，将来，过去将来体分为：一般（在某个时间点），进行（延续某个时间

2、段），完成（完成某个时间段）完成进行 （延续某个完成的时间段）如此以来，英语中就有16种时态变化，现在就用动词为write例，看看它们的形式。注意：里面的斜体字部分，由于时态过于复杂，几乎没有人真正去应用它们，可以忽略不记。时间体现在过去将来过去将来一般Write(s)WroteShall writeWill Should writeWould 进行AmIs writingareWas writingwereShall Be writingwillShould Be writingWould 完成Have writtenhasHad writtenShall Have writtenwillS

3、houldHave writtenwould完成进行HaveBeen writhinghasHad been writingShall Have been writhingwillShouldHave beenWritingwould下面就常用的12种时态，（其中还有三种相对用的较少的，请注意）。具体分析一下。一 一般现在时表示现在的时间“点”上发生的动作或者状态，常用于以下的情况1、经常重复发生的动作或存在的状态，多与often, always, usually, sometimes, everyday, 等时间状语连用。He takes a walk after supper everyd

4、ayMy mother and father work at the same company.2、表示性格，特征，能力。Mr. Smith hates fish and never eats any.3、表示客观真理或者普遍事实。The sun rises in the east.二 一般过去时表示过去某时发生的动作或者状态，常和表示过去某个时间“点”的时间状语(yesterday, last week, 3 years ago, in 1987)连用She bought a car last week.He came to help me at that time.三 一般将来时表示将来的

5、时间“点”上发生的动作或者状态。The train will arrive soon.We shall know the news tomorrow.四 过去将来时 过去某个时间“点”上将要发生的动作或状态。I asked her where she would spend her holiday.I told my father that I should go home next Monday.五现在进行时表示现在的时间“段”上正在延续进行的动作或者状态。Im doing some washing.What are you doing?六 过去进行时在过去某一个时间“段”正在延续进行的动作

6、。I was working in my office at eight oclock yesterday evening.He was making a phone call when I saw him.七 将来进行时在将来某个时间“段”正在发生的动作，一般表示一种猜测和未来的计划，一般不太常用。What will you be doing at 3 oclock tomorrow afternoon?（明天下午三点你将在做什么哪）八 现在完成时表示动作在一个时间“段”的完成，而且这个时间段是从过去某一点延续到现在的。经常跟时间状语 since 1987， for 10 hours , b

7、y the last year相连。My brother has been ill for 3 days.I have not seen her since 1991.九 过去完成时在过去的某个时间“段”里动作的完成，从过去的一点再到过去的另一点。或者称为过去的过去。He said that he had written her a letter.Helen rang me up after I had gone to sleep.十 将来完成进行时表示在将来某一时间以前已经完成的动作，一般不太常用。Ill have done all the work by next day.十一。现在完成进

8、行时表示从过去某一个时间开始一直延续到现在的动作，它强调在这个已经完成的时间“段”，动作持续的进行，常有感情色彩。I have been looking for you everywhere for the whole morning.我找了你整整一天了。（有抱怨的感情色彩）十二。过去完成进行时正个时间段都是发生在过去的，是过去的一点延续到过去的另一点，并且强调动作的持续进行，带感情色彩，但一般不常用。He told me he had been teaching for more than 20 years.最后提醒一下：某些与时态规律不太一致的规则。表示一般将来的意思的，除了一般将来时态外
