几种时态动词变化

第七节几种时态的构成汇总

一、名词复数的变化规律

1、规则变化

1) 一般情况直接在词尾加-s . 如：chair—chairs；apple—apples；grape—grapes；desk—desks 等。

2）以s、sh、ch、x等结尾的词加–es .如：bus—buses；watch—watches；box—boxes；brush—brushes等。

3）以辅音字母+y结尾的词，变y 为i 再加es，baby—babies；city—cities；family—families 等。

4）以f或fe结尾的将f或fe直接换成ves. 如：knife—knives；thief—thieves；shelf—shelves 等。

2、不规则变化

1）没有规律的变化。如：child—children；foot—feet；tooth—teeth；mouse—mice；woman —women等。

2）单复同形。如：deer—deer；sheep—sheep；fish—fish；yuan—yuan；tofu—tofu；pork—pork等。

3）以o结尾的名词有的加es有的加s. 如：potato—potatoes；tomato—tomatoes；Hero—heroes等。

二、动词第三人称单数的变化规则

1）直接在动词后+s. 如：like—likes；play—plays；read—reads；get—gets；help—helps；ski —skis等。

2）以s, x, sh, ch, 接尾的动词：+es. 如：wash—washes；wacth—watches；teach—teaches；brush —brushes等。

3）以辅音+o接尾的动词：+es. 如：go—goes；do—does等。

4）以辅音+y接尾的动词：变y为i+es. 如：fly—flies；study —studies；carry—carries；sky —skies等。

末尾字母y前为元音字母的，直接在动词后面加-s. 如：play—plays；say—says等。5）特殊变化。如：be—is；have—has等。这些没有规律，需要加强记忆。

三、动词现在分词-ing形式的构成

1）一般情况在动词原形后加-ing . 如：go—going；stand—standing；climb—climbing等。2）以不发音的e结尾的动词，去掉e，再加-ing. 如：write—writing；hope—hoping；care—caring 等。

3）以-ie结尾的动词应先将e去掉，将i变成y然后再加-ing. 如：die—dying，tie—tying等。4）如果动词最后一音节为重读闭音节，最后一个字母需要重复. 如：run—running；

stop—stopping；hop—hopping；plan—planning；star—starring；get—getting等. 但辅音x 是个例外，无需重复（x其实起着两个辅音的作用）。如：tax—taxing，relax—relaxing 等。

5）以-ee，-oe，-ye结尾的动词加-ing时应保留词尾e. 如：see—seeing；hoe—hoeing；eye—eyeing 等。

6）以-ue结尾的动词大多应先去e再加-ing. 如：sue—suing；imbue—imbuing；rue—ruing 等。

7）以-ic结尾的动词应先在字母c后加一字母k再加-ing. 如：frolic—frolicking；

panic—panicking；mimic—mimicking；picnic—picnicking；traffic—trafficking等。

四、动词的过去式变化

1、规则变化

1）一般情况下，在动词词尾直接加-ed. 如：work—worked；piay—played；want—wanted；act—acted

等。

2）以不发音的-e 结尾动词，在动词词尾加-d. 如：live—lived；move—moved；decide—decided 等。

3）以辅音字母+ y结尾的动词，把-y变为-i 再加-ed. 如：study—studied；try—tried；cry--cried 等。

4）以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加–ed, 如：stop—stopped；

beg—begged；fret—fretted；drag—dragged；drop—dropped；plan—planned；dot—dotted；

drip—dripped 等。

2、不规则变化的动词有很多，规律性不强，需要加强记忆。

高考中需要掌握的各种时态的分析： 一般现在时： 构成： 谓语动词：do/does 系动词：be~is/am/are 被动语态：am/is/are+done 何为现在？ 无论过去，现在，还是将来，只要跟现在搭上边，统统都是现在。所以一般过去时和他就没有任何的关系。 一般现在：等于常态 主语现在所具备的个性，能力或特征。 经常性或习惯性的动作。 普遍真理?客观事实?格言警句。 按照规定，时间表或安排要发生的动作。（时刻表） 主语现在所具备的个性，能力或特征 This machine does not work. It has not worked for years. 这台机器不工作了。它已经不工作好几年了。 经常性或习惯性的动作 I do all the cooking for my family. 我们家所有的烹饪都是我来做。 普遍真理?客观事实?格言警句 Columbus proved that the earth is round. 哥伦布证明地球是圆的。 按照规定，时间表或安排要发生的动作 Look at the Timetable.Hurry up！Flight 4026 takes off at 18：20. 你看看时刻表。抓紧点，4026号航班6:20就起飞了。 一般过去等于讲故事 奥义：一般～只需知道动作存在或发生。

何为过去？ 只能发生或存在于过去，不能跟现在产生任何关系。如果跟现在产生联系的话，那么它的概念就应该是现在时而不是过去。 构成： 谓语动词：did 被动语态：was/were+done George said that he would come to school to see me the next day，but he didn't. 乔治说他第二天会到学校来看我，但是他没来。 现在完成：用过去的事说现在。 构成： 谓语动词～Have done/Has done 系动词～ Have been /Has been 被动语态～Have been done/Has been done 我们用以下两种方式来说明： 第一：如果一个动作到现在为止，他已经结束了，那么这个动作一定是发生在过去。 第二：如果这个动作在过去发生的某一段时间之内，就结束了，他的动作没有延续到现在，但是它的影响是持续到现在的，于是与现在产生了关联，那就是说这是过去的动作对现在造成了影响。 从以上的描述我们可以总结出关于完成时态的两个要点： 过去的动作对现在造成了影响 过去的动作持续到现在 过去的动作对现在造成的影响或结果 例如：Look！Somebody has cleaned the sofa. Well,it wasn't me,I didn't do it. 看，有人把沙发清洗了。 嗯，不是我弄的，我没做这件事。 过去的动作或状态持续到现在 I remember you were a talented pianist in college.Can you play the piano for me? Sorry，I haven't played the piano for years. 我记得你上大学的时候特别有钢琴天赋。你能为我演奏钢琴吗？

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。
