定义:
名词是人类认识事物所使用的基本词汇,是用来表示人、事物、地方、现象或抽象概念的名称的词。在句中可以作主语、宾语、表语、定语、状语、称呼语等。
分类:
名词分为专有名词和普通名词,普通名词又分为可数名词和不可数名词。
考点:
1、可数名词变复数
⑴加-s。如desk-desks,dog-dogs
⑵以s,x,sh,ch,z等结尾,在词尾加-es,如:class-classes,bus-buses,watch-watches
⑶以f或fe结尾,变f或fe为v加-es。如:knife-knives,wife-wives
⑷以辅音字母加y结尾,变y为i,加-es。如:family-families,city-cities
⑸以辅音字母加o结尾,加-es。如:tomato-toamoes,hero-heroes
⑹特殊变化。如▲man-men,foot-feet,mouse-mice,child-children
▲sheep-sheep,deer-deer,fish-fish,Chinese-Chinese
2、集合名词做主语
⑴有些名词不能用a,one,two等具体数词修饰,只能在其前面加the表示“全体…”。
如:the people,the police,the cattle等。这些词作主语时谓语动词用复数。
⑵有些名词作主语时,谓语动词既可以是单数也可以是复数。
如:public,family,class,team,group等。
3、不可数名词量的表示
不可数名词不能和数词直接连用。他们可以和一下词语或词组连用:
some/any,little,a little,much,a lot of等。
男性药极品虎王a piece of,a pound of,a cup of,a bar of,a loaf of等。
4、名词所有格
⑴一般的情况在词尾加’s,以s结尾的加s’。如:the boy’s bag,boys’ bags
⑵无生命东西的名词用of属格。如:the window of the room
⑶东西为两人共有,只在后一个名词后面加’s。如:Lily and Lucy’s room
⑷名词所有格所修饰的词,有时可以省略。如the doctor’s
⑸双重所有格:▲a,an,this,that+名词+of+名词性物主代词。如:a friend of mine
▲可为名词+of+名词的所有格。如:a teacher of my sister’s
