不定冠词a的用法有哪些？
a英语不定冠词(a/an)用法要点
1、用 a 还是用an：一般说来，在辅音或半元音开头的词前用a, 而在元音开头的词前用an:
The hen laid an egg. 那只母鸡生了个鸡蛋。
She has an inborn love of jokes. 她天生爱开玩笑。
The child has an upset stomach. 这孩子肚子不舒服。
注意：有些以元音字母开头的单词，由于第一个音不是元音而是辅音，其前仍用a而不用an：
He has a university degree in economics. 他取得大学经济学学位。
st1:country-region w:st="on">Italy is a European country. 意大利是个欧洲国家。
The family lived in a one-room shack. 一家人住在一间简陋的小屋里。
