冠词的用法 THE ARTICLE 冠词的用法: 冠词 定冠词 不定冠词 零冠词 * 不定冠词的基本用法 不定冠词有“a和an”两种形式。 a用在以辅音音素开头的词前,而不是辅音字母前; an用在以元音音素开头的词前,而不是元音字母前, 如hour,首字母为辅音,但第一个发音是“a?”,故用an university 虽首字母为元音,但发音以“jU:”开头,故用a * 例2 There is ____ “f” and ____ “u” in the word “four”. A. an, a B. a, a C. an, an D. a, an 分析 在名词前使用a或an要取决于该名词的读音。如果首字母的读音是元音因素,应用an;如果首字母的读音是辅音音素,应用a。 A * 1. 用于可数名词的单数形式之前,表示一 =one   There is a man in the room. 2. 表示“某一个”的意思 =a certain   A Mr. Wang wants to see you. 3 表示每一的意思 =per We go swimming four times a week 4. 用在序数词前,表示“又一”,“再一”=another I have three books.
