英语在小升初考试中占有一定比重,备战小升初应该从了解英语的知识点开始。下面是查字典小考网小编为大家分享的小升初英语知识点讲解名词，供大家参考！
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。
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
