形容词和副词
一、形容词基本用法 1.形容词放在名词前作定语
Eg:a good boy an old man a beautiful girl 2.形容词修饰不定代词要后置
Eg:something interesting , nothing important
3.表示长(long)、宽(wide)、高(tall)、深(deep)、年龄(old)等词,应该置于名词之后
Eg:He is 10 yearsold. =He is a 10-year-old boy. The river is 20 meterswide. =It is a 20-meter-wride river. The building is 5 hundred meterstall. =It is a 500-meter-tall building.
4.只能做表语,不能做前置定语的形容词 alone、asleep、alive、awake、afraid、ill 5.多个形容词作定语修饰名词时,形容词排列顺序
限定词→一般描绘性形容词→表示大小、长短、高低的形容词→表示年龄、新旧的形容词→表示国籍、地区、出处的形容词→表示物质、材料的形容词+名词
口诀:限冠形龄色国材。或限定描绘大长高,颜色国籍和材料。 6.The+adj表示一类人
