1、1冠词的用法详解英语中冠词分为定冠词 the 和不定冠词 a/an 两种。冠词一般不单独使用，往往放在名词前面，表示不同的意义。一：a 和 an 区别A 用于辅音前，an 用于元音前。特别注意的是 an 用于元音因素（发音）而不是字母前。1. 拼写以辅音字母开头读音却以元音开头的单词hour, honest, honor 等单词的拼写虽然以辅音字母 h 开头，但其读音却以元音开头，因此，前面要用 an。可熟记下面这句话：An hour ago, an honest man accepted an honorable task. (一小时前，一位诚实的人接受了一项光荣的任务。)2. 拼写以元音字
2、母开头读音却以辅音开头的单词useful, university, usual, European, united, one-eyed, one-way 等单词的拼写虽然以元音字母开头，但其读音却以元音开头，因此，前面要用 a。可熟记下面这句话：In a university, a European and a one-eyed man walk along a one-way road with a usual tool. This is a usual thing. (在一所大学里，有一个欧洲人和一个独眼龙拿着有用的工具沿着一条单行道行走，这是件平常的事。)如：Five years ago

(上海卷)A. a; the B. an; the C. an; / D. a; /【分析】答案选 D。因为 university 是以辅音j 开头的要用 a，排除 B 和 C；physics 是学科名词，前面不用冠词。3. 英文字母前用 a 还是用 an 的问题在 26 个英文字母中，A ei, e i, f ef, h eitf I ai, lel m em , n en o ou ra sesx eks等 12 个字母的读音是以元音开头的，因此前面要用 an。其余字母则是以辅音开头的。

(全国卷)A. an B. the C. / D. a2There is a “u ,an m and a p in the word “jump:.【分析】答案选 A。因为字母 m 的发音是以元音e开头的，所以用 an；这里的 an 的意义与 one 相当，表示“一个”。an NBA star 一个篮球明星 an MIT student. 一个麻省理工的学生二：不定冠词的用法1：表示“一个”与“one ”相同Rome wasnt built in a d
