初中英语知识归纳总结2 冠词

一、概述

冠词是一种虚词,在句子中不重读,本身不能独立使用。在汉语中没有这个词类。在学习冠词时,要注意这种加在名词前帮助说明名词所指的人或事物的词表示数量“一”时,与数词的区别;其表示“数量”的意义没有“one”强,这是学习中注意区别的。

二、冠词的定义

冠词是置于名词之前,说明名词所表示的人或事物的一种虚词,它不能离开名词而单独存在。冠词有两种:

一种是定冠词(the Definite Article);the

一种是不定冠词(the Indefinite Article). a  an

三、不定冠词的用法

a用于辅音音素起首的单词前,an用于元音音素起首的单词前。

1、当第一次提到某人或某物时,用a或an起介绍作用,如:

What is this?     It is a bus.

Who is she?         She is a doctor.

A snake is a cold-blood animal.

A plane is a machine that can fly.
