1、精选优质文档-倾情为你奉上初中英语导学:初中英语动词时态和语态辨析初中英语动词时态和语态讲解动词是谓语动所表示的动作或情况发生时间的各种形式。英语动词有16种时态,但是常用的只有9种:一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时、过去将来时、现在完成进行时。下面分别介绍。1、 一般现在时的用法1) 表示经常性、习惯性的动作;表示现在的状态、特征和真理。句中常用 often, usually, every,sometimes 等时间状语。例如:a. He goes to school every day. 他每天去上学。b. He is very happy

2、. 他很开心。c. The earth moves around the sun. 地球围绕太阳转。(特性)2) 在时间状语从句和条件状语从句中,用一般现在时表示将来。例如:a. If you come this afternoon, well have a meeting. 如果你今天下午过来,我们将开个会。b. When I graduate, Ill go to countryside. 毕业后我要去乡下。3) 有时这个时态表示按计划、规定要发生的动作(句中都带有时间状语),但限于少数动词,如:begin, come, leave, go ,arrive, start , stop, r

3、eturn, open, close等。例如:a. The meeting begins at seven. 会议七点开始。b. The rain starts at nine in the morning. 上午九点开始下雨。4) 表示状态和感觉的动词(be, like, hate, think, remember, find, sound 等)常用一般现在进行时。a.

4、去时的用法 1)在确定的过去时间里所发生的动作或存在的状态。例如:时间状语有:yesterday, last week, an hour ago, the other day, in 1982等。例如: Where did you go just now? 刚才你上哪儿去了? 2)表示在过去一段时间内,经常性或习惯性的动作。例如: When I was a child, I often played football in the street. 我是个孩子的时候,常在马路上踢足球。 Whenever the Browns went during their visit, they were

5、given a warm welcome. 那时,布朗一家无论什么时候去,都受到热烈欢迎。 3)句型: is time for sb. to do sth “到时间了” “该了”。例如:It is time for you to go to bed. 你该睡觉了。 is time that sb. did sth. “时间已迟了” “早该了” ,例如It is time you went to bed. 你早该睡觉了。 (had) rather sb. did sth. 表示宁愿某人做某事。例如:Id rather you came tomorrow.还是明天来吧。 4) wish, wond

6、er, think, hope 等用过去时,作试探性的询问、请求、建议等,而一般过去时表示的动作或状态都已成为过去,现已不复存在。例如:I thought you might have some. 我以为你想要一些。 比较:Christine was an invalid all her life.(含义:她已不在人间。) Christine has been an invalid all her life.(含义:她现在还活着) Mrs. Darby lived in Kentucky for seven years. (含义:达比太太已不再住在肯塔基州。) Mrs. Darby has l

7、ived in Kentucky for seven years. (含义:现在还住在肯塔基州,有可能指刚离去) 注意: 用过去时表示现在,表示委婉语气。 1)动词want, hope, wonder, think, intend 等。例如: Did you want anything else? 您还要些什么吗? I wondered if you could help me. 能不能帮我一下。 2)情态动词 could, would。例如: Could you lend me your bike? 你的自行车,能借用一些吗? 重点学习一下,used to / be used to used

8、 to + do:”过去常常”表示过去习惯性的动作或状态,但如今已不存在。例如: Mother used not to be so forgetful. 老妈过去没那么健忘。 Scarf used to take a walk. 斯卡夫过去常常散步。 be used to + doing:对已感到习惯,或”习惯于”,to是介词,后需加名词或动名词。例如: He is used to a vegetarian diet. Scarf is used to taking a walk. 斯卡夫现在已习惯于散步了。 典型例题 - Your phone number again? I _ quite

9、catch it. - Its . A. didnt B. couldnt C. dont D. cant 答案A. 本句虽没有明确的时间状语,但从语意上看出,在听的时候没有听懂这个动作发生在过去,因此应用过去时。 3.一般将来时的用法一般将来时表示将来的动作或状态。其表达形式除了 “ will 或 shall + 动词原形 ”表示即将发生的或最近打算进行的事。 is going to rain. 要下雨了。 are going to have a meeting today. 我们今天要开个会。2)“be to + 动词原形” 表示按计划进行或征求对方意见。 boy is to go to

10、school tomorrow. 男孩明天要去上学。 we to go on with this work? 我们要继续这项工作吗?3) “be about to+ 动词原形” 表示即将发生的动作,意为 be ready to do sth. 后面一般不跟时间状语。 We are about to leave. 我们正要离开。4) go , come , start, move, sail, leave, arrive ,stay 等可用进行时态表示按计划即将发生的动作。例如:Im leaving for Beijing. 我要离开北京了。5) 某些动词(如come, go ,leave, a

11、rrive, start, get , stay 等)的一般现在时也可表示将来。例如: meeting starts at five oclock. 会议将在五点开始。 gets off at the next stop. 他要在下一站下车。我们重点学习一下,be to和be going to be to 表示客观安排或受人指示而做某事,be going to 表示主观的打算或计划。例如: I am to play football tomorrow afternoon. 明天下午我去踢球。(客观安排) Im going to play football tomorrow afternoon.

12、 明天下午我想去踢球。(主观安排)4. 一般现在时表将来 1)下列动词come, go, arrive, leave, start, begin, return的一般现在时可以表示将来,主要用来表示在时间上已确定或安排好的事情。例如: train leaves at six tomorrow morning. 火车明天上午六点开。 does the bus star? It stars in ten minutes. 汽车什么时候开?十分钟后。 2)以here, there等开始的倒装句,表示动作正在进行。例如: comes the bus. = The bus is coming. 车来了。

13、 goes the bell. = The bell is ringing. 铃响了。 3)在时间或条件句中。例如: Bill comes (不是will come), ask him to wait for me. 比尔来后,让他等我。 ll write to you as soon as I arrive there. 我到了那里,就写信给你。 4)在动词hope, take care that, make sure that等的宾语从句中。例如: hope they have a nice time next week. 我希望他们下星期玩得开心。 sure that the windo

14、ws are closed before you leave the room. 离开房间前,务必把窗户关了。 5. 用现在进行时表示将来 下列动词come, go, arrive, leave, start, begin, return等现在进行时可以表示将来。例如: m leaving tomorrow. 明天我要走了。 you staying here till next week? 你会在这儿呆到下周吗? 6. 现在完成时 现在完成时用来表示之前已发生或完成的动作或状态,其结果的影响现在还存在;也可表示持续到现在的动作或状态。其构成:have(has) +过去分词。 重点: 比较一般过

15、去时与现在完成时 1)一般过去时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响。 2)一般过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语。 一般过去时的时间状语:yesterday, last week,ago, in1980, in October, just now等,皆为具体的时间状语。 现在完成时的时间状语:for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always

16、等,皆不确定的时间状语。 共同的时间状语:this morning, tonight, this April, now, already, recently, lately 等。 3)现在完成时可表示持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know.。 一般过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。例如: saw this film yesterday. (强调看的动作发生过了) have seen this film. (

17、强调对现在的影响,电影的内容已经知道了) did you get up so early? (强调起床的动作已发生过了) hasnt handed in his paper? (强调有卷子未交,疑为不公平竞争) has been in the League for three years. (在团内的状态可延续) has been a League member for three years. (是团员的状态可持续) 句子中如有过去时的时间副词(如yesterday, last, week, in 1960)时,不能使用现在完成时,要用过去时。 (错)Tom has written a le

18、tter to his parents last night. (对)Tom wrote a letter to his parents last night. 用于现在完成时的句型 1)It is the first / second time. that结构中的从句部分,用现在完成时。例如: It is the first time that I have visited the city. 这是我第一次访问这城市。 This is the first time (that) Ive heard him sing. 这是我第一次听他唱歌。 注意:It was the third time

19、that the boy had been late. 2)This is +形容词最高级+that结构,that 从句要用现在完成时。例如: This is the best film that Ive (ever) seen. 这是我看过的最好的电影。 典型例题 (1) -Do you know our town at all? -No, this is the first time I _ here. A. was B. have been C. came D. am coming 答案B. This is the first time 后面所加从句应为现在完成时,故选B。 (2) -H

20、ave you _ been to our town before? -No, its the first time I _ here. A. even, come B. even, have come C. ever, come D. ever, have come 答案D. ever意为曾经或无论何时,反意词为never,此两词常用于完成时。 注意:非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。 (错)I have received his letter for a month. (对)I havent received his letter for

21、almost a month. 重点: 比较since和for Since 用来说明动作起始时间,for用来说明动作延续时间长度。例如: I have lived here for more than twenty years.我住在这儿二十多年了。 I have lived here since I was born. 我从出生起就住在这儿了。 注意:并非有for 作为时间状语的句子都用现在完成时。 I worked here for more than twenty years. (我现在已不在这里工作。) I have worked here for many years.(现在我仍在这

22、里工作。) 注意:用句型转换的方法,很容易排除非延续动词在有for/since结构的完成时中的误用。 1)(对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now. 2)(错) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now. 显然,第二

23、句不对,它应改为 Harry got married six years ago. 或 Harry has been married for six years. 7. since的四种用法 1) since +过去一个时间点(如具体的年、月、日期、钟点、1980, last month, half past six)。例如: I have been here since 1989. 1989起,我一直在这儿。 2) since +一段时间+ ago。例如: I have been here since five months ago. 我在这儿,已经有五个月了。 3) since +从句。例

24、如: Great changes have taken place since you left. 你走后,变化可大了。 Great changes have taken place since we were here. 我们走后,变化可大了。 4) It is +一段时间+ since从句。例如: It is two years since I became a postgraduate student. 我考上研究生有两年了。 8. 延续动词与瞬间动词 1) 用于完成时的区别 延续动词表示经验、经历; 瞬间动词表示行为的结果,不能与表示段的时间状语连用。例如: He has comple

25、ted the work. 他已完成了那项工作。 (表结果) Ive known him since then. 我从那时起就认识他了。(表经历) 2) 用于till / until从句的差异 延续动词用于肯定句,表示”做直到” 瞬间动词用于否定句,表示”到,才”。例如: He didnt come back until ten oclock. 他到10 点才回来。 He slept until ten oclock. 他一直睡到10点。 典型例题 1. You dont need to describe her. I _ her several times. A. had met B. ha

26、ve met C. met D. meet 答案B. 首先本题后句强调对现在的影响,我知道她的模样,你不用描述。再次,several times告知为反复发生的动作,因此用现在完成时。 2. -Im sorry to keep you waiting. -Oh, not at all. I _here only a few minutes. A. have been B. had been C. was D. will be 答案A. 等待的动作由过去开始,持续到现在,应用现在完成时。 9. 过去完成时 1) 概念:表示过去的过去 其构成是had +过去分词构成。-|-|-|- 那时以前那时现

27、在 2) 用法 a. 在told, said, knew, heard, thought等动词后的宾语从句。例如: She said (that)she had never been to Paris. 她告诉我她曾去过巴黎。 b. 状语从句 在过去不同时间发生的两个动作中,发生在先,用过去完成时;发生在后,用一般过去时。例如: When the police arrived, the thieves had run away. 警察到达时,小偷们早就跑了。 c. 表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时

28、表示”原本,未能”。例如: We had hoped that you would come, but you didnt. 那时我们希望你能来,但是你没有来。 3) 过去完成时的时间状语before, by, until , when, after, once, as soon as。例如: He said that he had learned some English before. 他说过他以前学过一些英语。 By the time he was twelve, Edison had began to make a living by himself. 到了十二岁那年,爱迪生开始自己谋

29、生。 Tom was disappointed that most of the guests had left when he arrived at the party. 汤姆失望了,因为他到达晚会时,大部分客人已经走了。 典型例题 The students _ busily when Miss Brown went to get a book she _ in the office. A. had written, left B,were writing, has left C. had written, had left D. were writing, had left 答案D. ”把

30、书忘在办公室”发生在”去取书”这一过去的动作之前,因此”忘了书”这一动作发生在过去的过去,用过去完成时。句中when表示的是时间的一点,表示在”同学们正忙于”这一背景下,when所引导的动作发生。因此前一句应用过去进行时。 注意: had hardly when 还没等 就。例如: I had hardly opened the door when I he hit me. 我刚打开门,他就打了我。 had no soonerthan 刚 就。例如: He had no sooner bought the car than he sold it. 他刚买了这辆车,转眼又卖了。 10. 用一般过

31、去时代替过去完成时 1) 两个动作如按顺序发生,又不强调先后,或用then,and,but 等连词时,多用一般过去时。例如: When she saw the mouse,she screamed. 她看到老鼠,就叫了起来。 My aunt gave me a hat and I lost it. 姑妈给了我一顶帽子,我把它丢了。 2 ) 两个动作相继发生,可用一般过去时;如第一个动作需要若干时间完成,用过去完成时。例如: When I heard the news, I was very excited. 3) 叙述历史事实,可不用过去完成时,而只用一般过去时。例如: Our teacher

32、 told us that Columbus discovered America in 1492. 11. 将来完成时 1) 构成will have done 2) 概念 a. 状态完成:表示某事继续到将来某一时为止一直有的状态。例如: They will have been married for 20 years by then. 到那时他们结婚将有二十年了。 b. 动作完成:表示将来某一时或另一个将来的动作之前,已经完成的动作或获得的经验。例如: You will have reached Shanghai by this time tomorrow. 明天此时,你已经到达上海了。 1

33、2. 现在进行时 现在进行时的基本用法: a. 表示现在(指说话人说话时)正在发生的事情。例如: We are waiting for you. 我们正在等你。 b. 习惯进行:表示长期的或重复性的动作,说话时动作未必正在进行。例如: Mr. Green is writing another novel. 他在写另一部小说。(说话时并未在写,只处于写作的状态。) c. 表示渐变,这样的动词有:get, grow, become, turn, run, go, begin等。例如: The leaves are turning red. 叶子在变红。 Its getting warmer and

34、 warmer. 天越来越热了。 d. 与always, constantly, forever 等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩。例如: You are always changing your mind. 你老是改变主意。 典型例题 My dictionary _, I have looked for it everywhere but still_ it. A. has lost, dont find B. is missing, dont find C. has lost, havent found D. is missing, havent fo

35、und. 答案D. 前句是一个仍在持续的状态,应用进行时,由于没有找到,其影响仍然存在,应用完成时,瞬间动词用于否定式时可用于完成时。 13. 不用进行时的动词 1)表示事实状态的动词,如have, belong, possess, cost, owe, exist, include, contain, matter, weigh, measure, continue等。例如:I have two brothers. 我有两兄弟。 This house belongs to my sister. 这房子是我姐的。 2)表示心理状态的动词,如know, realize, think see, b

36、elieve, suppose, imagine, agree, recognize, remember, want, need, forget, prefer, mean, understand, love, hate等。例如:I need your help. 我需要你的帮助。 He loves her very much. 他爱她很深。 3)瞬间动词,如accept, receive, complete, finish, give, allow, decide, refuse等。例如: I accept your advice. 我接受你的劝告。 4)系动词,如seem, remain,

37、 lie, see, hear, smell, feel, taste, get, become, turn等。例如: You seem a little tired. 你看上去有点累。 14. 过去进行时 1)概念:表示过去某时正在进行的状态或动作。 2)过去进行时的主要用法是描述一件事发生的背景;一个长动作延续的时候,另一个短动作发生。 3) 常用的时间状语有this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while等。例如: My brother fell w

38、hile he was riding his bicycle and hurt himself. 我兄弟骑车时摔了下来,受了伤。 It was raining when they left the station. 他们离开车站时,正下着雨。 When I got to the top of the mountain, the sun was shining. 我到达山顶时,阳光灿烂。 典型例题 1) Mary _ a dress when she cut her finger. A. made B. is making C. was making D. makes 答案C. 割伤手指是已发生

39、的事情,应用过去时。同时,when表时间的同时性,”玛丽在做衣服时”提供事情发生的背景,因此用过去进行时。 2) As she _ the newspaper, Granny _ asleep. A. read;was falling B. was reading; fell C. was reading; was falling D. read;fell 答案B.句中的as = when, while,意为”当之时”。描述一件事发生的背景时,用过去进行;一个长动作发生的时候,另一个短动作发生。句意为 “在她看报纸时,奶奶睡着了。”句中的 fell(fall的过去时),是系动词,后跟形容词,如

40、:fall sick动词语态1 当句子的主语是动作的执行者时, 谓语的形式叫主动语态。句子的主语是动作承受者时,谓语的形式叫被动作语态。被动语态由助动词be + 过去分词构成,时态通过be 表现出来。1) 一般现在时:You are required to do this.2) 一般过去时:The story was told by her.3) 一般将来时:The problem will be discussed tomorrow.4) 现在进行时:The road is being widened. 5) 过去进行时:The new tool was being made.6) 现在完成
