初中三年级英语名词要点：名词作定语形式及特征
作定语的名词有以下三种形式：A.一般用单数形式。a stone bridge 石桥a meeting room 会议室morning exercise 早操London Airport 伦敦机场a story book 故事书a shoe shop 鞋店B. man, woman要与所修饰的名词的单复数一致。a woman teacher 一位女教师two women teachers 两位女教师C. sports, sales, clothes, goods, arts, customs等只用复数形式。a sports meet 运动会a goods train 货车customs house 海关a sales manager 营业主任现从四个方面来讨论名词定语的特征：1、名词定语的语法用途1.代替作定语用的介词短语。a garden chair=a chair in the gardenCanada wheat=wheat from Canadasafety regulations=regulations for safetymachine shop practice=practice in a machine shop2.名词定语代替形容词或分词作定语。race problemracial problem
China cottonChinese cottonlaunch padlaunching padresearch workerresearching worker在以上词例中，用名词与用形容词或分词并没什么不同。3.代替带s的所有格定语--在名词前加上定冠词the就能代替名词的所有格，但这个名词是专有名词。the Tom composition=Toms compositionthe Carter grin=Carters grin4.代替定语从句。investment money= money that is set apart for investment.the milk boy= the boy who brings the milk.2、名词定语与被修饰语之间的语义关系作定语的名词都是后面一个名词的修饰语，但它们之间的关系却各有不同。1.名词定语表示逻辑上的主语，被修饰的词表示宾语。a department decision(a decision which is made by the department)the volcano eruption(the eruption that is made by the volcano)有时正好相反，名词定语等于宾语，而被修饰的部分表示主语:a drug addict(a person who is addicted to drug)an animal trainer(a man who trains the animal)2.名词定语作状语，被修饰语等于谓语。在这些结构中，表示谓语的名词常由动名词或动作名词来充当。impulse buying=buying on impulseinstrument flying=flying by means of instrument3.名词定语表示同位关系。这种使用方法可以说明某人的职业、职位。Judge Darling Singer Carpenter Cardinal Nelson。还可以表示特点、身份：a supplier country= a country which is a suppliera killer shark= a shark who is a killerher lawyer brother=her brother who is a lawyer
