不定冠词 知识点
不定冠词：a 和an
a 用于辅音发音开头的词前，而不是辅音字母前面，如：a book, a desk。 有些单词虽然是以元音字母开头，但需用a修饰，这些单词可以连成一句话：In a university, a European united a one-eyed man to steal a useful thing, then ran away along a one-way road. This is a usual thing.在一所大学里，一个欧洲人联合独眼龙偷了一件有用的东西，然后沿着一条单行道逃跑了。这是一件平常的事。
an 用于元音发音开头的词前，而不是元音字母前，如：an apple, an hour。有些单词虽然是以辅音字母开头，但发音却是以元音开头，这些单词可以连成一句话：An hour ago, an honest man accepted an honorable task.一个小时以前，一个诚实人接受了一项光荣的任务。
