语法 | 不定冠词的用法简述
冠词的学习是英语中很重要的一部分，冠词又分为定冠词和不定冠词以及零冠词。今天，小编为大家准备了相关的语法知识，将要为大家来讲解一下：不定冠词的概念和用法，一起来看看吧！1、 a / an 用在单数可数名词前面，表示这个人或事物是泛指的不确定的一个，相当于中文的“一个”。通常在第一次提到某人或某物时用a / an

用在不可数名词前面意义上也有变化如wood 木头, awood 一片树林power威力, a power大国 / beauty 美丽, a beauty美人, a strong wind 一阵强风
2、a 用在读音为辅音开头的名词之前,而 an 用在读音为元音开头的名词之前。例如： a university (虽然u 是元音字母，但不读元音。)an hour (虽然h 不是元音，但单词读音是元音开头)
3、用其中的任何一个，代表他们所属种类的特性。
