第二篇：第三人称名词单数变复数
动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同，请认真观察。
1、大多数动词在词尾加“S”在清辅音后发音为[s]，在浊辅音及元音后发音为 [z]。如： ①stop－stops [s] make－makes [s] ②read－reads [z] play－plays [z]
2、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读[iz] 如： fly－flies [z]； carry－carries [z] study－studies [z];worry－worries
3、以“s, x, ch, sh”结尾的，在词尾加“es”，发音为[iz] 如： teach－teaches [iz];watch－watches [iz]
4、以“o”结尾的动词，加“es”，读[z] 如： go－goes [z] do－does [z] 下面几个动词变为单数时，原词的元音部分的发音发生了较大的变化，请注意记忆。如：
1、do [du:]－does [dz]
2、say [sei]－says [sez] 以不发音字母“e”结尾的开音节词，如果尾音是[s]，[z]时，加“s”后字母“e”发音，与所加“s” 一起读做[iz]。如： close－closes [iz]
二、对比词形变化中原词词尾变化之异同： 变“y”为“”现象 双写最后辅音字母现象 例词：
①baby－babies ②carry－carries ③study－studying 动词第三人称单数词尾变化形式及读音 动词第三人称单数词尾变化有三种形式。(1)一般动词在词尾加-s，-s在清辅音后读／s／，在浊辅音或元音后读／z／，ds读／dz／，ts读／ts／。如：
help→helps／helps／，know→knows／nEuz／，get→gets／gets／，read→reads／ri:dz／(2)以字母s，x，ch，sh或有些以o结尾的动词加-es，-es读／iz／。如：
guess→guesses／'gAsiz／，fix→fixes／'fiksiz／，teach→teaches／'ti:tFiz／，wash→washes／'wRFiz／ 注意：go→goes／gEuz／，do→does／dQz／
(3)以辅音字母+y结尾的动词，先变y为i，再加-es，-ies读／iz／。如： carry→carries／'kAriz／，fly→flies／flaiz／ 注：在play→plays／pleiz／，say→says／sez／中，字母y前为元音字母，第三人称单数形式直接在动词后面加-s。(4)特殊词例外。如： be→is，have→has 1)单数名词加s: students, apples, bags, trees, books, brothers. 2)以s、x、sh、ch
结尾的名词加es: glasses, boxes, brushes, matches. 3)以辅音字母加y结尾的名词，变y为i加es: cities, babies, enemies.4)以f或fe结尾的名词，多数变f为v加es: wives, knives.但有些词只加s: roofs, proof s, chiefs. 5)以o结尾的名词，有些加es: Negroes, heroes, tomatoes, potatoes.s: radio s, zoos, pianos, photos.
其它
加6)不规则名词：foot→feet, goose→geese, tooth→teeth, child→children, man→me n, woman→women, sheep→sheep, deer→deer, mouse→mice.7)某些外来词变复数：datum→data, medium→media, bacterium→bacteria, curriculum→curricula, criterion→criteria, phenomenon→phenomena.(um/on→a)analysis→analyses, basis→bases, crisis→crises, diagnosis→diagnoses.(is→es)
8)复合名词变复数：以不可数名词结尾的复合名词无复数形式，如：homework. 以man或woman为前缀的复合名词变复数，前后两个名词都变复数，如：manservant→menservants, woman student women students.
其它复合名词变复数：grownup→grownups, brotherinlaw→brothersinlaw, standby→standsby. 9)复合形容词做定语时，其中的名词保持单数：a sixyearold boy，a twohundredpage book
1、大多数名词变复数时在末尾直接加“s”：book boy piano 以“s, x, sh, ch”结尾的名词变复数时在末尾加“es”：dress watch box
2、部分以“o”结尾的名词变复数时也要在末尾加“es”：hero nero potato mango tomato
3、以辅音加”y”结尾的名词变复数时在末尾将“y”改“i”加“es”：family baby puppy
4、以“f”或“fe”结尾的名词变复数时在末尾将“f”或“fe”改为“ves”：knife wife
5、部分名词属于单复数同形，名词复数还是其本身：sheep fish
6、部分名词本身就是复数：people glasses clothes
7、部分单词中含有字母组合“oo”，应将“oo”改为“ee”：foot goose
8、部分名词属于不规则变化，应专门记忆：man child mouse
9、不可数名词一般不使用复数形式：water milk 动词第三人称单数和过去式同时出现，变哪一个？ 变过去式
如 She bought a book yesterday.规则的变化有以下几种： 1.直接加s。
2.以s,sh,ch,x结尾的单词要加es。以s结尾的单词要加es，这个应该不会弄错，不然一个单词的复数形式的尾巴就是ss了。但是sh,ch结尾就很容易被忘记，而且因为在he,she,it做主语的一般现在时里，动词也是这种变化，所以一定要记住.比如watch->watches(手表;看);finish->finishes....x结尾的倒不是很多见(如boxes)3.以辅音字母加上y结尾的单词,去掉y加上ies.大家容易忽略的就是y前面一定要是辅音字母才要做这样的变化，像boy就不符合这个条件,平时记清楚了才不会在考试的时候突然犯迷糊。这种符合条件的例子有：baby->babies....而以y结尾的专有名词,则直接加s变复数，如the Henrys（亨利一家）4.以o 结尾的名词，变复数时，大多数都是直接加s, 除了hero, negro,potato,tamato这四个加es.5.以f或fe 结尾的名词变复数时,可以是加s，如：belief->beliefs，roof->roofs;也有去f,fe 加ves，如half->halves,knife->knives,leaf->leaves,wolf->wolves,wife->wives,life->lives,thief->thieves；没有什么确定的变化规则，去f,fe 加ves常用的都在这里了，多看几眼就记住了吧。还有handkerchief可以有handkerchiefs或者handkerchieves的变化，是特例里面的特例了。
++++++++++++++++++++++++++++++++++++++++++++ 一些练习：
1.Most of the houses in the village were burnt to ______ in the big fire.a.an ash b.the ash c.ash d.ashes 解答：be burned into ashes意思是“烧成了灰烬”；ash的复数形
式

1、大多数动词在词尾加“S”在清辅音后发音为[s]，在浊辅音及元音后发音为 [z]。如： ①stop－stops [s] make－makes [s] ②read－reads [z] play－plays [z]

第四篇：名词、第三人称单数
名词
可数名词有单数和复数两种形式。指一个人或一件事物时，用单数形式；指两个或多个人或事物时用复数形式。名词由单数形式变成复数形式的规则如下：
1.一般的名词词尾直接加-s。如：
book → books room → rooms house → houses day → days
2.以s, ss, ch, sh, x 结尾的名词，在词尾加-es。如：
bus → buses glass → glasses watch → watches dish → dishes box → boxes
3.以“辅音字母+y”结尾的名词，要先将y改为i再加-es。如：
city → cities body → bodies factory → factories等等。
4.以f 或fe 结尾的名词，要将f或fe改为v再加-es。如：
half → halves leaf → leaves knife → knives wife → wives
5.特例 [悄悄话：特例常常考，要记住。]
① child → children ② man → men woman → women
policeman → policemen(规律：man → men)
③ tomato → tomatoes potato → potatoes
[悄悄话： 初中英语以o 结尾的名词变复数时只有这两个词加-es，其余的当然加-s喽！如：photo → photos ]
④ foot → feet tooth → teeth [悄悄话： oo变成ee。]
⑤ sheep, Chinese, Japanese单、复数同形 [悄悄话：变复数时词形不变。]
⑥ people单数形式表示复数意义，要求谓语动词用复数； people的复数形式peoples通常指“多个民族”。
不可数名词
1.不可数名词没有复数，当它作句子的主语时，谓语动词要用单数形式。如：
The food is very fresh.食品很新鲜。
2.有的不可数名词也可以作可数名词，有复数形式，但他们的意义往往发生变化。如：
water(水)→ waters(水域)orange(橘汁)→ oranges(橘子)
3.很多的不可数名词表示泛指时为不可数，表示种类时就可数，但意义大多不发生变化。如：
fruit → fruits food → foods fish → fishes hair → hairs
三、不可数名词的数量表示 不可数名词不能与数词连用，但若要表示相应的数量，则需要借助一定的单位词等。如：
1、借助表示“张”、“块”的单位词（piece）a piece of paper一张纸 a piece of advice一条建议 a piece of news一条新闻 a piece of chalk 一只粉笔 a piece of bread一块面包 a piece of work 一项工作 a piece of meat 一块肉 a piece of ice 一块冰 a piece of information一条消息 a piece of music 一曲音乐 a piece of wood 一块木头 a piece of furniture 一件家具 注意：不要按照汉语习惯在不该用单位的地方错用单位词，如“一张邮票”只能说“a stamp”而不能说“a piece of stamp”。
2、借助表示容量的词 a bottle of ink一瓶墨水 a cup of tea一杯茶 a bowl of rice一碗米饭 a glass of beer一杯啤酒
3、借助表示重量的词 a kilo of salt一公斤盐 ten tons of coal十吨煤
4、借助表示形状的词 a drop of water一滴水 a grain of sand一粒沙
二、写出下列名词的复数形式

动词第三人称单数
在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。但有些同学们对于哪些主语是第三人称单数还不十分清楚，现归纳总结如下：
一、人称代词he, she, it是第三人称单数。如：
1.He likes cars.他喜欢车。
2.She goes to school at seven.她七点去上学。3.It has a good name.它有一个好名字。
二、单个人名、亲朋好友等称呼作主语 是第三人称单数。如：
1.Pat never throws rubbish on the floor.Pat从不在地板上扔垃圾。2.Miss Wang waters the flowers once a day.王老师给花一天浇水一次。3.Aunt Mary usually makes cakes.玛丽阿姨经常做蛋糕。
4.My mother washes the dishes everyday.我妈妈每天都洗碗。
三、第三人称单数形式的构成
1.一般直接在词尾加 s，如：work-works live-lives make-makes 2.以s, x, ch, sh等结尾的单词加 es , 如： miss-misses fix-fixes finish-finishes teach-teaches 3.以辅音字母加o结尾的单词，加 es 如: go-goes do-does
4、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es” 5.特殊变形的有： have-has
四、问句：问句中遇到第三人称单数时，需要用助动词does, 动词变为原形。What does she like? When does he brush his teeth? How often does your sister comb her hair?

第五篇：动词第三人称单数
动词第三人称单数
一、动词第三人称单数的变化规则及发音规律
动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同，请认真观察。
1、大多数动词在词尾加“S”在清辅音后发音为[s]，在浊辅音及元音后发音为 [z]。如：
①stop－stops [s];make－makes [s] ②read－reads [z];play－plays [z]
2、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读[iz] 如： fly－flies [z]； carry－carries [z] study－studies [z];worry－worries
3、以“s, x, ch, sh”结尾的，在词尾加“es”，发音为[iz] 如： teach－teaches [iz];watch－watches [iz]
4、以“o”结尾的动词，加“es”，读[z] 如： go－goes [z] do－does [z]
下面几个动词变为单数时，原词的元音部分的发音发生了较大的变化，请注意记忆。如：
1、do [du:]－does [dz]
2、say [sei]－says [sez]
以不发音字母“e”结尾的开音节词，如果尾音是[s]，[z]时，加“s”后字母“e”发音，与所加“s”
一起读做[iz]。如： close－closes [iz]
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，storey→storeys（楼层）；
4．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→zoos
b）加es的名词有：
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→gulfs
b）去掉f，fe 加ves的名词有：
half→halves knife→knives
leaf→leaves wolf→wolves
wife→wives life→lives thief→thieves
