1、a 与 an 的用法区别a 用于辅音前； an 用于元音前。一般说来，元音字母发元音(元音指元音音素而不是元音字母） ，辅音字母发辅音，但需请注意以下3点：1. 拼写以辅音字母开头读音却以元音开头的单词hour au, honestnist, honorn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，前面要用等单词的拼写虽然以辅音字母 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. 拼写以元音字母开头读音却以辅音开头的单词usefulj
2、u:sful , university ,ju:niv:sti, usual ju:ul, European ,jurpi:n, unitedju:naitid , one-eyed wnaid, one-way wnwei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 等单词的拼写虽然以元音字母开头，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.

4、母则是以辅音开头的。如：Please pay attention to your spelling. You have dropped _ ”m” here. (全国卷)A. an B. the C. / D. a【分析】答案选 A。因为字母答案选 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”。（一）音标测试：找出下列划线部分发音不同的单词.( ) 1. A. cake B. take C. nap D. wave( ) 2. A. bread B. eat C. tea D. seat( ) 3.
