英语名词单数变复数规则一、名词可数名词和不可数名词：1.定义：一般来说，个体名词和集体名词多为可数名词，物质名词和抽象名词多为不可数名词。

2.可数名词的数：可数名词有单数、复数之分，表示“一个”时用单数，a bird，a teacher，an apple，表示“多个”时用复数。

two birds，five teachers，eight apples.3.可数名词复数的变化规则.A、一般情况下，在单数名词的后面加-s构成。

如：game-games，boy-boys等。

B、以s、x、sh、ch结尾的单数名词变复数，在词尾加-es构成。

如：box-boxes，bus-buses，peach-peaches，dish-dishes。

C、以o结尾，表示有生命的事物的单数名词变复数加-es；表示没有生命的事物的单数名词变复数加-s。

如：potato-potatoes，tomato-tomatoes，photo-photos，piano-pianos等。

D、以辅音字母加y结尾的单数名词变复数，将y改成i后再加-es。

如：factory-factories，story-stories，family-families。

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.E、以f或fe结尾的单数名词变复数，将f或fe改成v，然后再加-es。

如：leaf-leaves，life-lives，knife-knives等。

F、名词单数变复数，除了有规则可循的变化之外，还有一部分的变化是不规则的，我们将这部分名词的变化叫做不规则变化。

这些词有：foot-feet，tooth-teeth，man-men，woman-women，mouse-mice，sheep-sheep，deer-deer, fish-fish, child-children, Chinese- Chinese, Japanese- Japanese，goose-geese, ox-oxen4.不可数名词量的表示不可数名词没有单数、复数之分，但我们在生活中有时候又必需给这些词计量，我们于是采用这种方法：a+表示这些东西的单位+of+不可数名词，如：a cup of tea，a box of milk，a piece of paper等。

如果为了表示多个的概念，我们就将表示这些东西的单位变成复数即可。

如：a cup of tea---3 cups of tea，a box of milk---12 boxes of milk，A piece of paper---100 pieces of paper英语动词变化规则二、动词变第三人称单数①一般情况加–s如：make- makes ; stop- stops ; help- helps②以s,sh,ch,x等结尾的词加–es如：dress- dresses; pass- passes ; wash- washes ; teach- teaches ; watch- watches ; fix- fixes③以辅音字母+y 变y 为i结尾的词再加es如：study- studies; fly- flies ; try- tries ; carry- carries④以元音字母加y结尾的词，直接加-es如：play- playes ；stay- stayes ; enjoy- enjoyes ;⑤以“o”结尾的动词，加“es”，如：go- goes ; do- does三、动词变现在分词（即-ing形式）1. 一般情况，加-ing 如：go- going ; ask- asking ; look- looking ; watch- watching2. 以不发音的e结尾的动词，去e，再加-ing如：write-writing ; make-making ; take-taking; practice-practicing ;3. 以重读闭音节结尾的动词，末尾只有一个辅音字母，双写这个辅音字母，再加-ing如：get- getting ; sit- sitting ; run- running ; put- putting ; begin- beginning ;swim- swimming ; stop- stopping ; plan- planning ; shop- shopping四．动词变过去式1. 一般情况，加-ed如：look- looked ; play- played ; start-started ; listen- listened2. 以e结尾的动词，加-d如：hope- hoped ; use- used ; live- lived ; decide- decided3. 以重读闭音节结尾的动词，末尾只有一个辅音字母，双写这个辅音字母，再加-ed 如：stop- stopped ; plan- planned; shop- shopped4. 以辅音字母加y结尾的动词，变y为i，再加-ed如：study-studied ; carry-carried ; worry-worried ; try-tried ;五、动词变过去式过去分词不规则变化英语中有些动词的过去式和过去分词形式变化不规则，可主要分为几种情况。
