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)
