初中英语语法大全：冠词

冠词是虚词，本身不能单独使用，也没有词义，它用在名词的前面帮助指明名词的含义。冠词分为不定冠词a(an)和定冠词the两种。不定冠词仅用在单数可数名词前面，表示“一”的意义，但不强调数目观念，只表示名词为不特定者。定冠词则表示名词为特定者，表示“这”、“那”、“这些”、“那些”的意思，在可数的单复数名词或不可数名词前面都可以用。

I 不定冠词

We need an apple and a knife.

我们需要一个苹果和一把刀子。

1.a和an的区别

不定冠词有a[+]和an[+Q]两种形式，a用于辅音(不是辅音字母)开头的词前。an用于元音(不是元音字母)开头的词前。

a boy, a university, a European country

u是元音字母，但发音是[U(]，是辅音。

an hour ，an honor ，an island

h是辅音字母，但它不发音，它的音标是是元音。

an elephant， an umbrella， an egg
