1、常见的八种英语时态详解时态（Tense）是表示行为、动作和状态在各种时间条件下的动词形式。因此，当我们说时态结构的时候，指的是相应时态下的动词形式。 英语时态分为 16 种一般时态 进行时态 完成时态 完成进行时态现在 do/does Am/is/are doing Have/has done Have/has been doing过去 did Was/were doing Had done Had been doing将来 Shall/will do Shall/will be doing Shall/will have doneShall/will have been doing过去将来
2、Should/would do Should/would doing Should/would have doneShould/wouldhave been doing1. 一般现在时 基本结构： be 动词 am/is/are； 行为动词原形或单数第三人称。 否定形式： am is are _；此时态的谓语动词若为行为动词，则在 其前加_，如主语为第三人称单数，则用_，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，用 does，同时，还原行为动词。提示词：always , everyday , often , once a week (m
3、onth , year , etc.) , sometimes , seldom , usually 1) 描述当前时间内经常出现、反复发生的动作或存在的状态。She doesnt often write to her family, only once a month.It seldom rains here .这儿很少下雨。2）仅为了描述状态、性质、特征、能力等等。这里的目的是为了“描述现阶段的动作或状态 “，其重点 “不是强调动作发生的时间、或进行的状态“。例如：He can speak five foreign languages .Changjiang River is one of
4、 the longest rivers in the world. 3) 陈述客观事实、客观真理。The earth goes around the sun .地球绕着太阳转。4) 根据英文语法规定，当主句的谓语动词是一般将来时，那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。例如：Ill tell him the news when he comes back. 他回来时，我将告诉他这个消息。If you take the job , they will talk with you in greater details.5）现在时的特殊用法：一般现在时表过去1. 用于

16、在外面吃饭。Are you staying here till next week? 你要在这儿呆到下星期吗？ 现在进行时与一般现在时均可表示将来，区别是：用现在进行时表示将来，其计划性较强，并往往暗示一种意图；而一般现在时表示将来，则其客观性较强，即通常被视为客观事实，多指按时刻表或规定要发生的情况：Im not going out this evening. 今晚我不准备出去。What time does the train leave? 火车什么时候开? 练习1）Look!

18、行的动作，所以，句子常带有一个表示“过去某个时间点”的状语。这个状语可能是短语，词组，或是一个从句。也可能是通过上下文来表达这层意思1）表示在过去某时刻正在进行的动作，例如：At this moment yesterday, I was packing for camp.What were you doing at eight last night ? 昨晚八点钟你在做什么？2）用于故事的开头，交代故事发生的背景情况。过去进行时所描述的动作是“正在进行”，所以，在这种情景中用“过去进行时”可以给读者一种“动感” ，从而能使文章更加生动活泼。例如：One night, he was typing
19、 in his study . Suddenly , a man broke into his house and cut off the electricity 3)（仅限少数动词）表示在过去的未来时间要发生的动作。例如：She told me that she was going to Hainan for her holidayWe left there when its getting dark. 练习1）He _(do) his homework at two oclock yesterday afternoon.2)They_(have）a meeting from 8 to 10
20、 last night.3)Mary_(wash) her clothes when we came in.4)At that time the boy _(play) football 。5)While we _(talk) with Mr.Wang in English , a foreigner came up .6.过去完成时一、过去完成时的概念与结构特点概念：过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作，即“过去的过去（ past-in-the-past ）“ 。-|- |-|-那时以前 那时 现在 构成：过去完成时由“助动词 had + 过去分词“ 构成，其中 ha
21、d 通用于各种人称。They had already had breakfast before they arrived at the hotel.She had finished writing the composition by 10 ：00 this morning.二、过去完成时的判断依据1. 由时间状语来判定一般说来，各种时态都有特定的时间状语。与过去完成时连用的时间状语有：（ 1 ） by + 过去的时间点。如： I had finished reading the novel by nine oclock last night. （ 2 ） by the end of + 过去
22、的时间点。如： We had learned over two thousand English words by the end of last term.（ 3 ） before + 过去的时间点。如： They had planted six hundred trees before last Wednesday.2. 由“过去的过去 “来判定。过去完成时表示“过去的过去 “，是指过去某一动作之前已经发生或完成的动作，即动作有先后关系，动作在前的用过去完成时，在后的用一般过去时。这种用法常出现在：（ 1 ）宾语从句中当宾语从句的主句为一般过去时，且从句的动作先于主句的动作时，从句要用过去
23、完成时。在 told, said, knew, heard, thought 等动词后的宾语从句。如：She said that she had seen the film before. （ 2 ）状语从句中 在时间、条件、原因、方式等状语从句中，主、从句的动作发生有先后关系，动作在前的，要用过去完成时，动作在后的要用一般过去时。如：When I got to the station, the train had already left.After he had finished his homework, he went to bed.注意： before, after 引导的时间状语从
24、句中，由于 before 和 after 本身已表达了动作的先后关系，若主、从句表示的动作紧密相连，则主、从句都用一般过去时。如：Where did you study before you came here?After he closed the door, he left the classroom.（ 3 ）表示意向的动词，如 hope, wish, expect, think, intend, mean, suppose 等，用过去完成时表示“原本 ，未能“We had hoped that you would come, but you didnt.3. 根据上、下文来判定。I m
25、et Wang Tao in the street yesterday. We hadnt seen each other since he went to Beijing.三、过去完成时的主要用法 1. 过去完成时表示一个动作或状态在过去某一时间或动作之前已经完成或结束，即发生在“过去的过去 “。如：When I woke up, it had stopped raining.我醒来时，雨已经停了。（主句的动作发生在“过去的过去“ ）2. 过去完成时是一个相对的时态，表示的是“过去的过去“ ，只有和过去某一时间或某一动作相比较时才使用它。如：He told me that he had wr
26、itten a new book. (had written 发生在 told 之前 )3. 过去完成时需要与一个表示过去的时间状语连用，它不能离开过去时间而独立存在。此时多与 already ， yet ， still ， just ， before ， never 等时间副词及 by ， before ， until 等引导的短语或从句连用。如：Before she came to China, Grace had taught English in a middle school for about five years. Peter had collected more than 30
27、0 Chinese stamps by the time he was ten.4. 过去完成时表示某一动作或状态在过去某时之前已经开始，一直延续到这一过去时间，而且动作尚未结束，仍然有继续下去的可能。如： By the end of last year, he had worked in the factory for twenty years. （ had worked 已有了 20 年，还有继续进行下去的可能）四、过去完成时与现在完成时的区别现在完成时表示的动作发生在过去，但侧重对现在产生的结果或造成的影响，与现在有关，其结构为“助动词 have (has) + 过去分词“；过去完成时则
28、是一个相对的时态，它所表示的动作不仅发生在过去，更强调“过去的过去“ ，只有和过去某时或某动作相比较时，才用到它。试比较：I have learned 1000 English words so far.到目前为止我已经学会了 1000 个英语单词。I had learned 1000 English words till then.到那时为止我已经学会了 1000 个英语单词。- Im sorry to keep you waiting. 对不起，让你久等了。- Oh, not at all. I have been here only a few minutes.没什么，我只等了几分钟。（
29、“等“ 的动作从过去某一时间点持续到现在）- John returned home yesterday. 约翰昨天回到家的。- Where had he been?他去哪儿了？（答语中使用过去完成时是指约翰在 returned home 之前去了哪些地方，即“ 过去的过去“ ）五、过去完成时与一般过去时的区别虽然这两种时态都表示过去发生的动作或存在的状态，但在使用时应注意以下几点： 1. 时间状语不同：过去完成时在时间上强调“过去的过去“ ；而一般过去时只强调过去某一特定的时间。试比较：They had arrived at the station by ten yesterday.They arrived at the station at ten yesterday.
