可数名词 知识点
概念:可数名词指的就是在数量上可以计数,可以数出数量的事物;可数名词单数前可以加上冠词a/an。
可数名词单数变为复数的规律:
1、一般名词复数是在名词后面加上“s”。如map→maps,bag→bags,book-books等
2、以s,x,sh,ch结尾的词加“es”。如bus→buses,watch→watches, box-boxes等。
3、部分以f或fe结尾的名词变复数时,去掉f,fe 加ves的名词有:half→halves knife→knives leaf→leaves wolf→wolves wife→wives life→lives thief→thieves 。
4、以o 结尾的名词变复数时:
a)加s的名词有(无生命):photo→photos ,piano→pianos,radio→radios
b)加es的名词有(有生命):potato→potatoes tomato→tomatoes
5、以辅音字母+y结尾的词,变y为i加es。如:baby→babies, family-families, study-studies等;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,storey→storeys(楼层)
6、oo变ee的单词,如:foot→feet, goose→geese, tooth→teeth。
7、a变e的单词。如:man→men, woman→women, policeman→policemen。
8、复数与原形一致的单词。如:fish→fish, sheep→sheep, deer→deer, Chinese→Chinese, Japanese→-Japanese。
注:1)fish指“鱼肉”时,是不可数名词;
2)fish指“鱼的多少”时,是可数名词,但单数和复数同行;There are many fish in the river。
3)fish强调鱼的“种类“时,复数是“fishes”。There are many kinds of fishes in the river。
9、有些名词以-s结尾,但表达的是单数意义,例如:news,maths,politics,physics,the United States等。
10、常以复数形式出现的名词,例如:glasses,trousers,shoes,gloves,socks等,要表达他们的量时常用pair,例如:a pair of glasses/shoes; 复数只需量词变复数,例如:two pairs of shoes
11、名词作定语时,不用复数形式,如:a shoe shop→shoe shops。如果要表示复数,则去掉不定冠词,把名词词组中的最后一个名词变成复数形式,如:an apple tree→apple trees
