12§2 a和an的用法
在英文里，a有时必须用an代替，凡是一个字一开始的发音是元音的话，那么前面就不能用a，而必须用an。例子：
an apple
an answer
an egg
an eye
an island
an idea
an old lady
an odd case
an umbrella
请注意，用an与否并不是完全和字母有关，而是和发音有关。举例来说，u虽然是一个元音字母，但是我们却说a unit，而不能用＊an unit，因为unit的一开始发音并非元音。
其它类似的例子有：
a useful car
a university
a uniform
a one-sided opinion
反过来说，有些字并不以元音开始，但是却必须用an，因为这些字的第一音节是元音发音，例子：
an honest person
an hour
