英语语法：冠词.doc

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 countryu是元音字母，但发音是U(，是辅音。an hour ，an honor ，an islandh是辅音字母，但它不发音，它的音标是是元音。an elephant， an umbrella， an egg2（1）不定冠词的用法泛指类人或物。eg.
