英语形式变化规则
在英语中,名词、动词和形容词等单词的形式会发生变化,以适应不同的语法需求。
以下是一些常见的形式变化规则:
1. 名词的变化:
-单数变复数:通常在名词末尾加上-s或-es。
例子:book(书)→books(书籍)
-复数变单数:通常去掉复数形式的-s或-es。
例子:desks(桌子)→desk(桌子)
2. 动词的变化:
-一般现在时的第三人称单数:通常在动词末尾加上-s或-es。
例子:go(去)→goes(去)
-现在分词:通常在动词原形后加上-ing。
例子:play(玩)→playing(玩)
-过去式:常见的过去式形式有两种,一种是直接在动词原形末尾加上-ed,另一种是根据变化规则进行变化。
例子:walk(走)→walked(走过);eat(吃)→ate(吃过)
3. 形容词的变化:
-比较级:通常在形容词前加上more或者加上-er。
例子:happy(快乐)→happier(更快乐);beautiful(美丽)→more beautiful(更美丽)
-最高级:通常在形容词前加上most或者加上-est。
例子:happy(快乐)→happiest(最快乐);beautiful(美丽)→most beautiful(最美丽)
需要注意的是,英语中还存在一些不规则变化的单词,它们的形式变化与上述规则不同。
因此,在学习英语时,除了掌握常见的形式变化规则,还需要特别关注不规则变化的单词。

动词第三人称单数复数分词变化规则
动词第三人称单数复数分词变化规则动词在第三人称单数、复数和分词形式上的变化规则如下:
1.第三人称单数变化规则:
通常在动词的原形后加上-s、-es或-ies。
例如:
- walk(步行)→ walks
- eat(吃)→ eats
- go(去)→ goes
- study(学习)→ studies
- fly(飞行)→ flies
2.第三人称复数变化规则:
对于大多数动词,只需在动词的原形后加上-s。
例如:
- walk(步行)→ walk
- eat(吃)→ eat
- go(去)→ go
- study(学习)→ study
- fly(飞行)→ fly
3.分词变化规则:
- 现在分词:通常在动词的原形后加上-ing。
例如:
- walk(步行)→ walking
- eat(吃)→ eating
- go(去)→ going
- 过去分词:通常把动词原形的尾音变为-ed,但也有一些特殊情况需要少量改动。
例如:
- walk(步行)→ walked
- eat(吃)→ eaten
- go(去)→ gone
需要注意的是,有些动词在变化时会有一些不规则的变化形式,这些需要特殊记忆和学习,例如:
- be(是)→ is(第三人称单数), are(第三人称复数), been (过去分词)。

英语动词的形态
英语动词的形态
英语动词有五种基本形式,即动词原形、第三人称单数(现在式)、过去式、过去分词和现在分词。
1.动词的原形。
指的是使用动词本身的形态,即与助动词或情态
动词一起构成谓语的动词时,要用原形。
2.第三人称单数现在式。
在动词原形后加-s、-es、-ies等。
3.过去式。
规则变化:在动词原形后加-ed等;不规则变化:原
型与过去式、过去分词同形或完全不同形。
4.过去分词。
规则变化:在动词原形后加-ed等;不规则变化:
原型与过去式、过去分词同形或完全不同形。
5.现在分词。
在动词原形后加-ing。

动词第三人称单数变化规则1) 一般情况下,动词后面直接加-s. 例如:works gets says reads2) 以ch,sh,s,x 或o 结尾的动词,在后面加-es。
例如:go-goes teach-,teache wash-washes brush-brushes ,catch-catches ,do-does ,fix -fixes3) 以辅音字母+ y结尾的动词,把y变为i 再加-es. 例如:study- studies try-tries carry-carries ,fly-flies cry-cries现在分词变化规则1.直接+ ing(例:sleep+ing sleeping)2.去e+ing(例:bite-e+ing biting)3重读闭音节,且末尾只有1个辅音字母,双写辅音字母+ing(例:sit+t+ing sitting)4.特殊变化:die-dying,lie-lying,tie-tying5.不规则变化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:We are waiting for you.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:Mr. Green is writing another novel.(说话时并未在写,只处于写作的状态。
)例:She is learning piano under Mr. Smith.C.已经确定或安排好的将来活动I'm leaving for a trek in Nepal next week.(已经安排了)we're flying to Paris tomorrow.(票已经拿到了)D.有些动词(状态动词不用于进行时态)1.表示知道或了解的动词:believe,doubt,forget,imagine,know, remember,realize,suppose,understand2.表示“看起来”“看上去"appear,resemble,seem3表示喜爱或不喜爱hate,like.lover.prefer4表示构成或来源的动词be come from.contain,include5表示感官的动词hear see smell sound taste6表示拥有的动词belong to.need.own .possess.want wish1、现在进行时的构成现在进行时由"be+v-ing"构成。
be应为助动词,最容易被同学漏掉,它应与主语的人称和数保持一致。
2、现在进行时的应用(1)当句子中有now时,常表示动作正在进行,这时要用现在进行时。
如:They are playing basketball now.现在他们正在打篮球。
(2)以look, listen开头的句子,提示我们动作正进行,这时要用现在进行时。
如:Listen!She is singing an English song.听,她正在唱英语歌。
(3)表示当前一段时间或现阶段正在进行的动作,且此时有this week, these days 等时间词,这时常用现在进行时。
如:We are making model planes these days.这些天我们在做飞机模型。
(4)描述图片中的人物的动作,也为了表达更生动。
此时也常用现在进行时。
如:Look at the picture. The children are flying kites in the park.看这幅图,那些孩子正在公园放风筝。
3、现在分词的变化规则:(1)一般情况下,直接在动词后加-ingwork ---- workingsleep ----- sleepingstudy ----- studying(2)动词以不发音的-e结尾,要去-e加-ingtake ----- takingmake ----- makingdance ----- dancing(3)重读闭音节的动词,要双写词尾字母,再加-ingcut ----- cuttingput ----- puttingbegin ------ beginning(4)以-ie结尾的动词,把变成y再加-inglie ----- lyingtie ----- tyingdie ----- dying4、现在进行时的变化肯定句式:主语+be( am, is, are)+现在分词+其它.否定句式:主语+be(am, is, are) +not +现在分词+其它.一般疑问句:be(am, is, are) +主语+现在分词+其它特殊疑问句:疑问词+be(am, is, are)+主语+现在分词+其它① 一般单音节词末尾加er 和est② 单音节词如果以e结尾,只加r 和st③ 闭音节单音节词如末尾只有一个辅音字母,须先双写这个辅音字母,再加er和est④ 少数以y,er(或ure),ow,ble结尾的双音节词,末尾加er和est(以y结尾的词,如y前是辅音字母,把y变成i,再加er和est,以e结尾的词仍加r和st)many much more most little less least far farther further farthest furthest old older elder oldest eldest 小贴士1:elder 和eldest 可用来表示兄弟和子女的长幼顺序: my elder sister 我的姐姐 my eldest brother 我的大哥 their eldest son 他们的长子小贴士1:further 表示“较远”外,还可表示 “进一步的”;而farther 仅表示距离:The farther plants are too cold. 更远的行星太冷。
Do you need any further help? 你还需要更进一步的帮助吗?2. 双音节词除了以“辅音+y”结尾的词外,还有以ow, er, le 结尾的词,和个别其他双音节词,可以用加词尾的办法构成比较级和最高级: 原级 比较级 最高级 narrow narrower narrowest clever cleverer cleverest simple simpler simplest common commoner commonest3. 也有少数单音节词可以加more 和most 的办法构成比较级和最高级: 原级 比较级 最高级 pleased more pleased most pleased tired more tired most tiredglad more glad most glad名词的复数形式英语里有一些名词的复数形式不是以词尾-s或-es构成,其它名词复数的规则变化1) 以y结尾的专有名词,或元音字母+y 结尾的名词变复数时,直接加s变复数:如:two Marys the Henrysmonkey---monkeys holiday---holidays比较:层楼:storey ---storeys story---stories2) 以o 结尾的名词,变复数时:a. 加s,如:photo---photos piano---pianosradio---radios zoo---zoos;b. 加es,如:potato--potatoes tomato--tomatoesc. 均可,如:zero---zeros / zeroes3) 以f或fe 结尾的名词变复数时:a. 加s,如:belief---beliefs roof---roofssafe---safes gulf---gulfs;b. 去f,fe 加ves,如:half---halvesknife---knives leaf---leaves wolf---wolveswife---wives life---lives thief---thieves;c. 均可,如:handkerchief:handkerchiefs / handkerchieves名词复数的不规则变化1)child---children foot---feet tooth---teethmouse---mice man---men woman---women注意:与man 和woman构成的合成词,其复数形式也是-men 和-women。
如:an Englishman,two Englishmen. 但German不是合成词,故复数形式为Germans;Bowman是姓,其复数是the Bowmans。
2)单复同形如:deer,sheep,fish,Chinese,Japaneseli,jin,yuan,two li,three mu,four jin但除人民币元、角、分外,美元、英镑、法郎等都有复数形式。
如:a dollar, two dollars; a meter, two meters3)集体名词,以单数形式出现,但实为复数。
如people police cattle 等本身就是复数,不能说 a people,a police,a cattle,但可以说a person,a policeman,a head of cattle,the English,the British,the French,the Chinese,the Japanese,the Swiss 等名词,表示国民总称时,作复数用。
如:The Chinese are industries and brave. 中国人民是勤劳勇敢的。
4)以s结尾,仍为单数的名词,如:a. maths,politics,physics等学科名词,为不可数名词,是单数。
b. news 是不可数名词。
c. the United States,the United Nations 应视为单数。
The United Nations was organized in 1945. 联合国是1945年组建起来的。
d. 以复数形式出现的书名,剧名,报纸,杂志名,也可视为单数。
"The Arabian Nights" is a very interesting story-book.<<一千零一夜>>是一本非常有趣的故事书。
5) 表示由两部分构成的东西,如:glasses (眼镜) trousers, clothes若表达具体数目,要借助数量词pair(对,双); suit(套); a pair of glasses; two pairs of trousers6)另外还有一些名词,其复数形式有时可表示特别意思,如:goods货物,waters 水域,fishes(各种)鱼动词变名词1.在词尾加er,r ,双写加er 或or:A. play _ player, sing _ singer, wait _ waiter , find _ finder,thrill _ thrillerB. write _ writer, drive _ driver, come _ comer, explore _ explorerdance _ dancerC. run _ runner, win _ winner, rob _ robber, traval _ travallerD. visit _ visitor, invent _ inventor2. 在词尾加ing:build _ building, draw _ drawing, end _ ending, begin _ beginning,swim _ swimming,skate _ skating, feel _ feeling, say _ saying,mean _ meaning, cross _ crossing,surf _ surfing, paint _ painting3.在词尾加ion 或去e加ion:A. decide _ decision, describe _ description, produce _ production,celebrate _ celebration,pronounce _ pronunciation, decorate _ decoration graduate _ graduation,frustrate - frustration,pollute _ pollutioncontribute _ contribution, congratulate _ congratulation,educate _ education,organize _ orgnization,donate _ donation,appreciate _ appreciation,operate _ operation, invite _ invitationB. discuss _ discussion, invent _ invention, attract _ attractionimpress _ impression,inject _ injection,instruct _ instruction4.其它:know _ knowledge, please _ pleasure, enjoy _ enjoyment,practise _ practice,die _ death, succeed _ success, weigh _ weight,sit _ deat, change _ chance,enter _ entrance,fly _ flight,rob _ robbery, discover _ discovery,faile _ failure,appear _ appearance, breathe _ breath清辅音浊辅音发音时引起声带振动的音叫浊辅音,不振动的叫清辅音。
