初中英语动词时态讲解及练习

16种英语时态总结归纳 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:一般现在、一般过去、一般将来、过去将来时,以及这四者的进行时、完成时和完成进行时。 1. 一般现在时 用法:A) 表示现在发生的动作、情况、状态和特征。 B) 习惯用语。C) 经常性、习惯性动作。 例:He always helps others. (他总是帮助别人。) D) 客观事实和普遍真理。尤其要注意,如果前后文不是一般现在时,则无法保持主句、从句时态一致。 E) 表示一个按规定、计划或安排要发生的动作,(仅限于某些表示“来、去、动、停、开始、结束、继续”等的动词)可以与表示未来时间的状语搭配使用。常见的用法是:飞机、火车、轮船、汽车等定期定点运行的交通方式。 例:The next train leaves at 3 o'clock this afternoon.(下一趟火车今天下午3点开车。) How often does this shuttle bus run? (这班车多久一趟?) F) 在时间和条件状语从句里经常用一般现在(有时也用现在完成时)表示将来事情。 例:When you have finished the report, I will have waited for about 3 hours.(等你完成这份报告的时候,我就已经等了将近3个小时了。) 2. 现在进行时(be doing) 用法:现在正在进行的动作。 3. 现在完成时(have done) 用法: A) 表示动作到现在为止已经完成或刚刚完成。 例:I bought a new house, but I _________ my old one yet, so at the moment I have two houses. A) didn't sell B) sold C) haven't sold D) would sell 答案是C) haven't sold。 B) 表示从过去某时刻开始,持续到现在的动作或情况,并且有可能会继续延续下去。此时经常用延续性动词。时间状语常用since加一个过去的时间点,或for 加一段时间,或by加一个现在时间。 例:Great as Newton was, many of his ideas ___________ today and are being modified by the work of scientists of our time. A) are to challenge C) have been challenged B) may be challenged D) are challenging 全句的意思是:“虽然牛顿是个伟大的人物,但他的许多见解直到今天还在受到挑战,并且被现代科学家的工作所修正。”challenge是及物动词,在本句中应当是被动语态;其动作延续到今天,所以要用现在完成时态。可见答案是C) have been challenged。A) are to challenge和D) are challenging都是主动语态,不可能是答案。B) may be challenged虽然是被动语态,但意思与全句内容不合,所以不对。 C) 表示发生在过去,但对现在仍有影响的动作或情况。通常用点动词,如:arrive, begin, find, give, lose等。 例:John has broken his left leg.(约翰摔断了左腿。) 注意事项 A) 现在完成时是联系过去和现在的纽带。现在完成时和过去时的区别在于:现在完成时强调动作的动态,或受动态的影响,是动态的结果,对现在有影响;过去时只表示过去的某个具体时间里发生的动作,与现在没有联系。

十六种英语时态总结(最新)

英语共有十六个时态、四个体。(注:四个体为——一般、进行、完成、完成进行。) 英语中的四个体相当于法语、西班牙语以及所有印欧语系罗曼语族中的式,如:直陈式,命令式等。 (1)一般现在时 基本形式(以do为例): 第三人称单数:does(主语为非第三人称单数); 肯定句:主语+动词原形+其他; He works for us. 否定句:主语+don…t/doesn't+动词原形+其他; He doesn't work for us. 一般疑问句:Do/Does+主语+动词原形+其他。 肯定回答:Yes,(+主语+do/does). 否定回答:No,(+主语+don't/doesn't.) 特殊疑问句:疑问词+一般疑问句语 Does he work for us? Yes, he does. No, he doesn't What does he do for us? He works for us. (2)一般过去时 be动词+行为动词的过去式 否定句式:在行为动词前加didn…t,同时还原行为动词,或was/were+not; 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 例如:Did he work for us? He didn't work for us. He worked for us. (3)一般将来时 am/are/is+going to+do 或 will/shall+do am/is/are/about to + do am/is/are to + do; 一般将来时的表达方法 be going to +动词原形

be +不定式,be to+动词原形,be about to +动词原形 be able to +不定式 be about to+动词原形 will + 动词原形; 例如:He is going to work for us. He will work for us; He is coming.这是特殊的用一般现在时表达将来时态的例子!! (4)过去将来时 be(was,were)going to+动词原形 be(was,were)about to+动词原形 be(was,were)to+动词原形 肯定句:主语+be(was,were)going to+动词原形~. 否定句:主语+be(was,were)not going to+动词原形~. 疑问句:Be(Was,Were)+主语+going to+动词原形~? 肯定句:主语+would(should)+动词原形~. 否定句:主语+would(should)not+动词原形~. 疑问句:Would(Should)+主语+动词原形~? He would work for us. (5)现在进行时 主语+be+v.ing〔现在分词〕形式(其中v表示动词) 表示现在正在进行的动作或最近在做的事。 例如:I am buying a book. 第一人称+am+doing+sth 第二人称+are+doing +sth (doing是泛指所有的v-ing形式) 第三人称+is+doing+sth 例:He is working. (6)过去进行时 肯定句:主语+was/were+doing+其它 否定句:主语+was/were+not+doing+其它 一般疑问句及答语:Was/Were+主语+doing+其它;答语:Yes,I主语+was/we re./No,I主语+wasn't/weren't. 特殊疑问句:特殊疑问词+was/were+主语+doing+其它 He was working when he was alive. (7)将来进行时

高考英语动词时态和语态讲解与专项练习题

动词时态语态 汉语的时态大多是通过副词来表达的,而英语的时态是靠动词的变化和时间状语来表达的。英语中常考的或较常用的有10种,而且重点测试完成时态。要掌握英语的时态和语态,必须掌握好英语中的助动词(do, be, have)和时间状语这两个核心问题。 1、一般现在时;主要用来表示人、事物的现在状况和特点;表示经常或习惯性的动作,句子中常有often, always, from time to time 等时间状语;表示客观规律和永恒真理;按照计划安排好了将要发生的动作(一般指时刻表)等。 He usua lly goes to work at 7 o’clock every morning. She has a brother who lives in New York. The earth goes around the sun. Guangzhou is situated in the south of China. 考点一:表示永恒的真理,即使出现在过去的语境中,仍用一般现在时。如:I learned that the earth goes around the sun when I was in primary school. 考点二:在时间和条件状语从句中,代替一般将来时;常用的引导词有:时间:when, until, after, before, as soon as, once, the moment/the minute, the day; 条件:if, unless, provided. If he accepts the job, he will get more money soon. 考点三:在make sure (certain), see to it, mind, care, matter +宾语从句,从句用一般现在时代替一般将来时。 So long as he works hard, I don’t mind when he finishes the experiment. 只要他努力工作,我不介意他什么时候做完试验。 考点四:在the more… the more … (越……越……) 句型中, 若主句是一般将来时, 从句用一般现在时。 The harder you study, the better results you will get. 2、现在进行时 表说话时或目前一段时间正在进行的活动:或表感情色彩,加强语气。与频率副词,如always,constantly,continually,again等连用表示说话人的某种感情色彩(赞叹、厌烦、埋怨等)。 We are having English class. The house is being built these days. The little boy is always making trouble. 考点一:在时间状语或条件状语从句中表示将来正在进行的动作。Look out when you are crossing the street. Don't wake him up if he is still sleeping at 7 tomorrow morning. 考点二:表示在最近按计划或安排要进行的动作(这时多有表示将来的时间状语)。 Marry is leaving on Friday. 3、现在完成时 表示动作发生在过去,完成在过去,但强调与现在情况仍有联系,其结果或影响仍存在。现在完成时有一些标志性的时间状语: (1)非延续动作:动作发生在过去,对现在有影响。(2)延续性动作:动作和状态的持续。现在完成时有一些标志性的时间状语: 考点一:for + 时间段;since + 时间点 They have lived in Beijing for five years. They have lived in Beijing since 1995. 考点二:常见的不确定的时间状语:lately; recently, just, already, yet, up to now; till now; so far, these days, Has it stopped raining yet ? 考点三:在表示“最近几世纪/ 年/ 月以来……”时间状语中,谓语动词用现在完成时。

英语16种时态详解

英语的16种时态 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。 1. 一般现在时 英语时态分为16种:一般现在、一般过去、一般将来、过去将来时,以及这四者的进行时、完成时和完成进行时。 用法:A) 表示现在发生的动作、情况、状态和特征。 B) 习惯用语。

C) 经常性、习惯性动作。 例:He always helps others. (他总是帮助别人。) D) 客观事实和普遍真理。尤其要注意,如果前后文不是一般现在时,则无法保持主句、从句时态一致。 E) 表示一个按规定、计划或安排要发生的动作,(仅限于某些表示“来、去、动、停、开始、结束、继续”等的动词)可以与表示未来时间的状语搭配使用。常见的用法是:飞机、火车、轮船、汽车等定期定点运行的交通方式。 例:The next train leaves at 3 o'clock this afternoon. (下一趟火车今天下午3点开车。) How often does this shuttle bus run? (这班车多久一趟?) F) 在时间和条件状语从句里经常用一般现在(有时也用现在完成时)表示将来事情。 例:When you have finished the report, I will have waited for about 3 hours.(等你完成这份报告的时候,我就已经等了将近3个小时了。)2. 现在进行时(be doing) 用法:现在正在进行的动作。 3. 现在完成时(have done) 用法:A) 表示动作到现在为止已经完成或刚刚完成。 例:I bought a new house, but I _________ my old one yet, so at the moment I have two houses. A) didn't sell B) sold C) haven't sold D) would sell 答案是C) haven't sold。 B) 表示从过去某时刻开始,持续到现在的动作或情况,并且有可能会继续延续下去。此时经常用延续性动词。时间状语常用since加一个过去的时间点,或for加一段时间,或by加一个现在时间。 例:Great as Newton was, many of his ideas ___________ today and are being modified by the work of scientists of our time. A) are to challenge C) have been challenged B) may be challenged D) are challenging 全句的意思是:“虽然牛顿是个伟大的人物,但他的许多见解直到今天还在受到挑战,并且被现代科学家的工作所修正。”challenge是及物动词,在本句中应当是被动语态;其动作延续到今天,所以要用现在完成时态。可见答案是C) have been challenged。A) are to challenge和D) are challenging 都是主动语态,不可能是答案。B) may be challenged虽然是被动语态,但意思与全句内容不合,所以不对。 C) 表示发生在过去,但对现在仍有影响的动作或情况。通常用点动词,如:arrive, begin, find, give, lose等。
