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、动词三单形式现在分词过去分词过去式变化及形容词副词级别变化
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. 词的分类
词类又叫词性,词类就是词的类别。我们知道,英语单词成千上万,但根据用法特征,可以分为十类。分别叫名词,代词,动词,形容词,副词,数词,连词,介词,冠词, 感叹词。也就是说,英语中那么多单词,任挑一个,那它一定属于这十种词类中的一种或几种。

含义
表示人、事物、地点或抽象概念的名称。 是用来指代人或事物的词。
表示用来修饰名词,表示名词属性的词。 是一种用来修饰动词、形容词、其他副词以及全句的词,说明时间、地点、程度、方式等概念。
表示动作或状态的词,动词根据其意义和作用可分为实义动词、系动词、情态动词和助动词。 表示“数量”和“顺序”的词。
volcano→volcanoes/volcanos
则
kilo→kilos,
变 化
以元音字母加-o 结尾的名词加-s
studio→studios,radio→radios, bamboo→bamboos, zoo→zoos
e.以字母 f 或 fe 结尾的单词,单数变复数时,将 f 或 fe 直接替换为 ves。
词 一般情况下,直接在动词后加“s” 第 三 人
名词变复数发音,动词过去式第三人称单数和现在分词
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]。
初中英语名词、动词、形容词各形式及变化规则
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。

动词原形+ing
大多数动名词是由动词原形+ing构成,例如 “reading”(阅读)。
少数动词以“-ing”结尾
有些动词的动名词形式直接以“-ing”结尾,例 如“going”(去)。
3
特殊变化的动词
有些动词的动名词形式需要进行特殊变化,例如 “running”(跑)。

03
作为介词宾语
动名词可以作为介词宾语,例如 “I am interested in reading books”(我对读书很感兴趣)。

不规则变化
01
有些名词的复数形式是不规则的, 需要单独记忆。例如: child→children,ox→oxen。
02
还有一些特殊的复数形式,如: man→men,woman→women, tooth→teeth等。
复合名词的复数形式
复合名词的复数形式通常是将复合名 词中的每个单词都变成复数形式。例 如:boyfriend→boyfriends。
Байду номын сангаас
动名词的时态和语态变化
时态变化
动名词可以表达过去、现在和未来 的时间,例如“running”(跑步) 可以表示现在进行时或过去进行时。
语态变化
动名词没有被动语态,但有时可以 用主动语态表示被动意义,例如 “cleaning the room”(打扫房 间)可以表示房间被打扫。

英语变形规律总结
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。

英语动词有五种基本形式
英语动词有五种基本形式: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。
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:一般情况下由动词后加-s构成:work / works,read / reads等。
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. 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。
复数-动词ing-过去式-比较级-adj.-adv.三单变化规则
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。

词性的变化形式
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。
语态的变化需要动词的不同形式。
三、形容词的变化形式形容词是描述人、事物的特征或者性质的词。
形容词的变化形式主要包括级别的变化和词性转换。
