英语名词复数变化规则
1. 一般在名词词尾加s。如:dog-dogs, house-houses, gram-grams,officer-officers.
2. 以s,ss,sh, ch及x结尾的名词加es构成其复数形式。如kiss-kisses,watch-watches, box-boxes, bush-bushes glass-glasses.
3. 以o结尾,注意以下几点:
(1)一般在词尾加es.如:tomato-tomatoes, potato-potatoes.
(2)如果是外来语或缩写名词, 则加s。如:piano-pianos, dynamo-dynamos, photo-photos, kimono-kimonos, biro-biros.(3)有些以o结尾的名词,其o前是元音字母则加-s。如:studio-studios, radio-radios.
(4)以oo结尾的名词只加s。如:zoo-zoos.
4. 以“辅音字母+ y“ 结尾的名词,则先把y改成i,再加es。如:baby-babies, university-universities, fly-flies, impurity-impurities.
5. 下列以f或fe结尾的名词,须先将f或fe改成v,再加es。这些名词是:calf, half , knife, leaf, life, loaf, self, sheaf, shelf, thief, wife, wolf 等。如:wife-wives, wolf-wolves, calf-calves.(像roof等词直接加s,如果是初中阶段,掌握roofs一个特别单词就行了)。
