人称代词+be动词+a/an+形容词+单数名词
a用于辅音前；an用于元音前。
一般说来，元音字母发元音，辅音字母发辅音，但需注意以下3点：
1. 拼写以辅音字母开头读音却以元音开头的单词
hour, 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。)
冠词a，an的用法：
【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
2.拼写以元音字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，但其读音却以辅音开头，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 her brother was ________ university student of ________ physics.
A. a; the B. an; the C. an; / D. a; /
【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 ”.
3. 英文字母前用a还是用an的问题
在26个英文字母中,a, e, i, o, f, h, l, m, n, r, s, x等12个字母的读音是以元音开头的，其余字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 　
用不定冠词“a”“an”填空。若不填“a”“an”，则用“×”表示。
1.I have＿＿apple,＿＿egg and some milk for breakfast.
2. ____ cat can catch mice.
3.Tom’s father is______ engineer.
4. Tony is ____ honest boy.
5. Mother bought me______uniform yesterday.
