英语单词复数形式的规律 1、名词由单数变复数的基本方法如下： ①在单数名词词尾加s..如：map → maps;boy→ boys;horse→ horses; table→ tables. ②s;o;x ;sh;ch结尾的词加es.如：class→classes; box→boxes; hero→heroes; dish→dishes; bench→benches. 注：少数以o结尾的词;变复数时只加s..如：photo→photos; piano→pianos. ③以辅音字母加y结尾的名词;变y为i;再加es..如：family→families; city→cities; party→parties. ④以f或fe结尾的名词;变f或fe为v;再加es..如：shelf→shelves; wolf→wolves; life→lives; knife→knives. 2、不规则变化：man→men; woman→women; sheep→sheep;tooth→teeth; fish→fish; child→children; ox→oxen; goose→geese 不可数名词一般没有复数形式;说明其数量时;要用有关计量名词..如：a bag of rice→two bags of rice; a piece of paper→three pieces of paper; a bottle of milk→five bottles of milk. 动名词的规则变化 1 一般情况下;直接在动词后加－ing 现在进行时 eg: work ---- working study ----- studying 2 动词以不发音的－e结尾;要去－e加－ing take ----- taking make ----- making 3 重读闭音节的动词;要双写词尾字母;再加－ing cut ----- cutting put begin 4 以－ie结尾的动词;把变成y再加－ing lie ----- lying tie ----- tying die ----- dying 现在分词的变化规则 1.普通动词+ing; 2.以不发音的e结尾的动词：去e+ing;例：dance→ dancing. 3.重读闭音节;以一个元音+一个辅音结尾的动 词：双写这个辅音字母+ing;例：stop→stopping. 4.以ie结尾的动词：变ie为y+ing.例lie→lying谎言;说谎;幌子 本文来源：https://www.wddqw.com/doc/ab1893d952e79b89680203d8ce2f0066f53364ff.html
