1、-作者xxxx-日期xxxx(三)冠词和数词及练习【精品文档】第三章 冠词和数词冠词是一种辅助性的词，不可在句中独立担任一个成分。放在名词前，帮助说明名词的含义，使用极为频繁。冠词有不定冠词（a, an）和定冠词（the）两种。a和an的基本含义是“一，一个”，表示泛指，不强调数目，只表示名词不是特定的；the的基本含义是“这个，那个”，表示特指，在可数的单复数名词或不可数名词前面都可以用。冠词本身是虚词，没有意义，同时也没有词义，它用在名词的前面，帮助指明名词的含义数词可分为基数词（Cardinal Numbers）和序数词（Ordinal Numbers）两种。前者表示数量，后者表示顺序。
