beautiful前面用a还是用an（a和an用法最简口诀）

用a,因为beautiful的第一个发音音标是辅音，不是元音，所以用a,不用an,例句如下:she is a beautiful girl.她是个漂亮女孩。

this is a beautiful dress.这是一条漂亮裙子。

he has a beautiful wife.他有一个漂亮的妻子。

this is a beautiful bag.good luck.

前面用a，例如：

1.Venice is a beautiful city full of culture and history.威尼斯是一座具有深厚文化和历史底蕴的美丽城市。

2.The town is in a beautiful situation in a wide green valley.小城坐落在宽阔而草木苍翠的山谷中，环境优美。

3.It's such a beautiful day!天气多么好哇！
