一、动词第三人称单数的变化规则及发音规律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－worries3、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]5、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、名词复数的规则变化___________________________________________________情况构成方法读音例词__________________________________________________一般情况加-s 1.清辅音后读/s/;map-maps2.浊辅音和元音后bag-bags读/z/;car-cars___________________________________________________以s,sh,ch,x等结尾的词加-es读/iz/bus-buseswatch-watches___________________________________________________以ce,se,ze,(d)ge等结尾的词加-s读/iz/license-licenses___________________________________________________以辅音字母+y变y 为i结尾的词再加es读/z/baby---babies___________________________________________________以-f或-fe结尾的名词多将-f或-fe变成-ves，但有例外，读音变化：尾音[f]改度[vz]。
例：life-lives leaf-leaves反例：roof-roofs___________________________________________________以O结尾的名词，如果不是外来词或缩写就加-es，否则加-s构成复数。
读音:[z]。
例：tomato-tomatoes反例：piano-pianos（外来词）photo-photos（缩写词）三、英语规则动词过去式变化规则和发音规则和不规则动词表1.规则动词的过去式词尾变化有几种：1．一般情况下加ed，如watched, planted, watered, pulled, climbed, picked。
2．以不发音字母e结尾的加d，如liked, moved, tasted。
3．以辅音字母加y结尾的变y为i再加ed，如study——studied。
4．以1个元音字母加1个辅音字母结尾的重读闭音节，双写最后一个辅音字母再加ed，如stop——stopped。
2.过去式的发音是由单词的最后一个音素来决定的:1.如果该单词以清辅音结尾,如/k/,/p/等,则读作/t/,例如looked读作/t/.2.如果该单词以浊辅音结尾,如/n/,/b/等,则读作/d/,例如abandoned读作/d/.3.如果该单词以字母t或字母d结尾,则读作/id/,例如started读作/id/.4.如果该单词以元音结尾,则读作/d/,例如studied读作/d/.3.不规则动词表Infinitive
