初中英语名词变复数-动词的单数第三人称形式、现在分词、过去分词-形容词、副词的比较级和最高级变化规律。

名词变复数名词变复数的规则变化1．一般名词复数是在名词后面加上“s”，如map→maps，bag→bags等；2．以s，sh，ch，x等结尾的词加“es”，如bus→buses，watch→watches等；3．以辅音字母＋y结尾的词，变y为“i”加“es”，如baby→babies等；以元音字母＋y结尾的名词变复数时，直接加“s”变复数，如monkey→monkeys，holiday→holidays；4．以o 结尾的名词变复数时：a）无生命的加“s”，名词有：photo→photos，piano→pianos，radio→radios，zoo→zoos b）有生命的加“es”，名词有：potato→potatoes，tomato→tomatoes；5．以f或fe结尾的名词变复数时：a）加“s”的名词有：belief→beliefs，roof→roofs，safe→safes，gulf→gulfsb）去掉f，fe加“ves”的名词有：half→halves knife→knives，leaf→leaves，wolf→wolves，wife→wives，life→lives，thief→thieves；名词变复数的不规则变化1）child→children，foot→feet，tooth→teeth，mouse→mice，man→men，woman→women （注意：由一个词加man 或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，Japanese.3）集体名词，以单数形式出现，但实为复数。

例如：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 herd of cattle. 4）以s结尾，仍为单数的名词，如：A. maths，politics，physics等学科名词，一般是不可数名词，为单数。

一名词的复数形式，一般在单数形式后面加s或es. 现将构成规则与读一名词的复数形式，一般在单数形式后面加s或es. 现将构成规则与读音规则音规则:二英语里有一些名词的复数形式不是以词尾-s或-es构成，它们的构成方法主要如下表：名词复数发音规则以元音音素结尾的加了“s”后发/z/音如：windows \ doors\ computers \centers以清辅音结尾的加了“S"后发/s/音如：chicks \ maps\ cups以字母t结尾的发/ts/音如：mats \ cats\ aunts以字母d结尾的发/dz/音如：birds \ words\ hands其他辅音音素结尾的都发/z/音。

特殊变化的词根据变化后结尾音变化同上如：butterfly-butterflies变化后结尾音/ai/为元音，所以发/z/音。

------------------------------------------------------------------------------------A．“单数→复数”的规则变化（1）名词词尾发音为[s, z, , , , ]时，加“-es”（如词尾有“-e”只加“-s”）并发[-iz]音，形成一个音节，也就是本项名词为单音节时，加了“-es”便成为双音节的单词。

class[kla:s]→classes[kla:siz]班级phrase[freiz]→phrases[freiziz]短语dish[di]→dishes[diiz]盘，碟garage[ 'gærɑ: ]→garages['gærɑ:iz]车库watch[ w ]→watches[ w iz]手表bridge[bri]→bridges[ br iiz]桥梁（2）名词词尾发音为[p, t, k, f, θ]等清辅音时，加“-s”并发[-s]音。

例如：cup[kp]→cups[kps]茶杯cat[kt]→cats[kts]猫book0[buk]→books[buks]书roof[ru:f]→roofs[ru:fs]屋顶month[mnθ]→months[mnθs]月注：“stomach”（胃），“monarch”（君主）等的复数是词尾加“-s”而不是加“-es”，因为这些词的词尾“-ch”的发音是[-k]。

一、英语动词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. 第三人称单数的构成方法与名词的单数变复数规则大致一样，即：(1) 一般情况下由动词后加-s构成：work / works，read / reads等。

(2) 以s, x, z, sh, ch 以及字母o结构的动词，后加-es：guess / guesses, mix / mixes, go / goes, buzz / buzzes, finish / finishes, catch / catches等。

(3)以辅音字母加y结尾的动词，应将y改为i 再加-es：fly / flies, study / studies等。

【注】①有个别的变化不规则，如have / has, be / is等。

②词尾-s和-es 读音规则是：在s, x, z, sh, ch 后的es读作[iz]，其余的读作[z]。

2. 过去式和过去分词的构成方法分规则变化和不规则变化两种。

不规则变化需逐个记忆，规则变化遵循以下原则：(1) 一般情况下，在动词后加ed构成：work / worked, stay / stayed, shout / shouted等。

(2) 在以-e结尾动词后只加d：close / closed, like / liked, live / lived, smile / smiled 等。

(3)以辅音字母加y结尾的动词，应将y改为i 再加-ed：study / studied, carry / carried等。

(4) 以重读闭音节或r音节结尾且末尾只有一个辅音字母动词，要双写末尾的辅音字母再加-ed：stop / stopped, admit / admitted, refer / referred, prefer / preferred等。

【注】(1) 以字母l结尾的动词，若末尾一个音节为重读音节，则必须双写l再加-ed，如control / controlled，但若末尾一个音节为非重读音节，则可双写l(英国英语)或不双写l(美国英语)，如travel / travel(l)ed。

重要语法知识回顾名词单数变复数规则：1) 一般情况加s2) 以s, x, sh, ch结尾加es，读/iz/。

buses, boxes, dishes, peaches等。

3) 以辅音字母+y结尾，变y为i再加es，读/iz/。

families, factories, stories。

4) 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，读/z/。

boys,toys等。

5）以辅音字母+o结尾的，有生命加es，读/iz/；无生命加s，读/z/。

negroes, heroes, vocanoes, potatoes,tomatoes, pianos, photos 等。

6）以f，fe结尾，去f，fe变ves，读/vz/。

wives, knives, lives, leaves，wolves, shelves,halves,thieves,themselves, ourselves等。

但是，roofs, gulfs, proofs,cliffs,beliefs, safes等。

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s, x, sh, ch或o 结尾的动词,在后面加-es。

go-goes teach-,teaches,wash-washesbrush-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. study- studies try-triescarry-carries ,fly-flies cry-cries但是destroys, plays, says, buys等。

现在分词的变化规则：1)一般在词尾加-ing（一般-ing）。

例如：going，playing，knowing2)以不发音的字母e结尾，先去e再加-ing（去哑e）。

英语变形规律总结英语单词的变形规律可以总结为以下几个方面：1. 名词的复数形式英语中大部分名词的复数形式是在词尾加上-s，例如：book-books, cat-cats, dog-dogs等。

但也有一些名词有不规则的复数形式，例如：child-children, mouse-mice, foot-feet等。

2. 动词的时态变化英语中的动词有三种基本时态：现在时、过去时和将来时。

在现在时，动词原形和第三人称单数形式是一样的，例如：I walk to school. He walks to school. 在过去时，大部分动词的过去式是在原形后加-ed，例如：I walked to school yesterday. He watched TV last night. 但也有一些动词的过去式是不规则的，例如：go-went, eat-ate等。

在将来时，动词前要加will或shall，例如：I will go to school tomorrow. They shall come to visit us next week.3. 形容词和副词的比较级和最高级形式形容词和副词的比较级和最高级形式都是通过在词尾加上-er和-est来表示的。

例如：big-bigger-biggest, fast-faster-fastest。

但也有一些形容词和副词的比较级和最高级形式是不规则的，例如：good-better-best, well-better-best等。

4. 不规则动词的变化规律在英语中，有一些动词的变化规律是不规则的，例如：go-went-gone, eat-ate-eaten等。

这些动词的过去式和过去分词形式都不是在原形后加-ed，而是需要记忆。

总之，英语单词的变形规律需要仔细学习和记忆，只有通过大量的练习才能掌握得更加熟练。

一、名词变复数规则：1．一般名词复数是在名词后面加上―s‖，如map→maps，bag→bags，book-books等；2．以s，x，sh，ch结尾的词加―es‖，如bus→buses，watch→watches, box-boxes等；3．以f或fe结尾的名词变复数时,去掉f，fe 加ves的名词有：half→halves knife→knives leaf→leaves wolf→wolves wife→wives life→lives thief→thieves4．以o 结尾的名词变复数时：a）加s的名词有：photo→photos ，piano→pianos，radio→radios，zoo→zoosb）加es的名词有：potato→potatoes tomato→tomatoes5．以辅音字母＋y结尾的词，变y为i加es，如baby→babies, family-families, study-studies等；以元音字母＋y结尾的名词变复数时，直接加s变复数，如monkey→monkeys，holiday→holidays，storey→storeys（楼层）；6. oo变ee的单词：foot-feet, goose-geese,tooth-teeth；7. a变e的单词：man-men, woman-women, policeman-policemen;8. 复数与原形一致的单词：fish-fish, sheep-sheep, deer-deer, Chinese-Chinese, Japanese-Japanese;9.最特殊的一个：German-Germans.二、第三人称单数时动词变化规则：1、一般现在时主语为第三人称单数时的动词变化①在一般现在时中，当主语为第三人称单数时，动词要用―s‖型（即第三人称单数形式）。

②所谓动词―s‖型的构成，可按名词变复数的规则来记，即：1. 在动词尾直接加s。

名词单数变复数变化规则1．一般名词复数是在名词后面直接加上“s”，如：map→maps，bag→bags，book-books等；2．以s，x，sh，ch结尾的词加“es”，如：bus→buses，watch→watches, box-boxes等；3．以f或fe结尾的名词变复数时,去掉f，fe 加ves的名词有：knife→knives leaf→leaves wife→wives life→lives thief→thieves4．以o 结尾的名词变复数时：a）加s的名词有（无生命）：photo→photos ，piano→pianos，radio→radios b）加es的名词有（有生命）：potato→potatoes tomato→tomatoes5．以辅音字母＋y结尾的词，变y为i加es，如：baby→babies, family-families, study-studies等；以元音字母＋y结尾的名词变复数时，直接加s变复数，如monkey→monkeys，holiday→holidays，storey→storeys（楼层）；6. oo变ee的单词：foot-feet, goose-geese,tooth-teeth；7. a变e的单词：man-men, woman-women, policeman-policemen;8. 复数与原形一致的单词：fish-fish, sheep-sheep, deer-deer, Chinese-Chinese,动词ing形式的用法及变化规则一．动词现在分词由动词原形在词尾加ing构成，其规则如下：1）一般情况下直接加ing think---thinking sleep---sleepingstudy---studying speak---speakingcarry---carrying say---saying2）以不发音的字母e结尾的单词，去掉字母e，再加ingwake---waking make---making come---comingtake---taking leave---leaving have---having3）以重读闭音节结尾，呈现“辅音，元音（a e i o u），辅音”结构的动词，先双写末尾的辅音字母，再加ing 。

英语中名词变复数与动词第三人称单数动词变复数：1．一般名词复数是在名词后面加上“s”,如eye→eyes,arm→arms等；2．以s,sh,ch,x等结尾的词加“es”,如bus→buses等；3．以辅音字母＋y结尾的词,变y为i加es,如baby→babies等；以元音字母＋y结尾的名词变复数时,直接加s,如monkey→monkeys等；4．以o 结尾的名词变复数时：a）加s的名词有：photo→photos,piano→pianos,radio→radiosb）加es的名词有：potato→potatoes,tomato→tomatoes5．以f或fe结尾的名词变复数时：a）加s的名词有：belief→beliefs,gulf→gulfs（裂口）b）去掉f,fe 加ves的名词有：knife→knives,leaf→leaves,动词第三人称单数的变化规则：①、一般情况下,词尾加s,如；like----likes,want----wants.②、以s,x,ch,sh,o结尾的加es,如,watch---watches,go---goes.③、以y结尾的归两大类：★元音+y要加s,如play----plays★辅音+y要变y为i+es如study---studies一般规则都是一样的,但以o结尾的名词变复数除了potato和tomato加es外其它的都加s.但变单三是以o结尾都加es英语名词复数变化及发音规则（NEW CONCEPT ENGLISH LESSON 16）1、一般在词尾加－s.一般来说，s在元音或浊辅音后读[z]，在清辅音后面读成[s]，在[t]后与[t]在一起读成[ts]，在[d]后与[d]一起读成[dz]。

cups 杯子books 书dogs 狗bags 包days 日子ties 领带hands 手bands 乐队hats 帽子suits 礼服2、以s,ss,sh,ch,x结尾的词在词尾加－es，读[iz]blouses 衬衫buses 公车classes 班级dresses 连衣裙dishes 碟子fishes 鱼watches 手表peaches 桃子boxes 盒子faxes 传真3、以“元音字母＋y”结尾的词，加－s，读作[z]；以辅音字母＋y结尾的词，变y为i，再加－es，读[iz]。

词性的变化形式词性的变化形式是语言中一个重要的语法现象。

不同的词性在不同的语境中会发生变化，以适应句子结构和语法规则。

本文将从名词、动词、形容词和副词等几个方面来讨论词性的变化形式。

一、名词的变化形式名词是指表示人、事物、抽象概念等的名字。

名词的变化形式主要包括单数和复数的变化、所有格和词性转换。

1. 单数和复数的变化大部分名词的复数形式是在词尾加上-s或-es。

例如：book（单数）→books（复数），cup（单数）→cups（复数）。

但也有一些名词复数形式有特殊变化，比如：man（单数）→men（复数），child（单数）→children（复数）。

2. 所有格名词的所有格表示所属关系或者身份。

一般情况下，名词所有格的形式是在名词的后面加上's。

例如：my father's car（我父亲的车）。

但对于以-s结尾的名词，只需要在名词的后面加上'。

例如：the boys' toys （男孩们的玩具）。

3. 名词的词性转换名词可以通过加上不同的后缀来转化为形容词或者动词。

例如：child（名词）→childish（形容词），friend（名词）→befriend（动词）。

二、动词的变化形式动词是表示动作、状态或者存在的词。

动词的变化形式主要包括时态、人称和语态的变化。

1. 时态的变化动词的时态表示动作发生的时间。

英语中常见的时态包括一般现在时、一般过去时、一般将来时等。

时态的变化通常需要动词的不同形式。

2. 人称的变化动词的人称表示动作的执行者或所涉及的人或物。

英语中的人称包括第一人称、第二人称和第三人称。

一般来说，动词在不同的人称下会发生变化。

3. 语态的变化动词的语态表示动作的执行者和承受者。

英语中的常见语态包括主动语态和被动语态。
