问题描述

an常用于元音音素开头的可数名词前,如:actor、actress、apple、orange、egg、eraser、eye、elephant、umbrella、hour、angle、American、island等。
a用于辅音音素开头的词前,an用于元音音素开头的词前。元音音素前用an(记住:是元音音素,不是元音字母)。如/ei/是元音音素,a是元音字母。有时元音字母发的是元音,前面就用an,有时不发元音,就要用a。如:an apple 一个苹果 an orange 一个橘子 an egg 一个鸡蛋 an important news 一条重要的新闻 an ugly girl 一个丑陋的女孩1,不定冠词a和an,用在可数名词单数前面。A birdis singing outside my window.一只鸟在我窗外欢歌。He always wears a hat when he goes out.他外出时总是戴顶帽子。It takes almost an hour for her to go to work every day.她每天上班路上几乎要花一个小时。抽象名词和一些数量众多的名词(如:盐salt, 沙sand, 稻米rice等)等不可数名词前不能用a或an。
2,a用在辅音开头的可数名词单数前,an用在元音开头的可数名词单数前。注意:这里不是以辅音字母和元音字母来分,而是单词第一个音节的读音区分,这就是我们重点要掌握的了:1) 多数以元音字母开头的单词,首音节都是发元音:I atean apple yesterday. It’s sweet.我昨天吃了一个很甜d的苹果。An artistis creative.艺术家是有创造力的。An Americanusually speaks English.美国人通常讲英语。Driving carefully helps avoid an accident.谨慎驾驶有助于避免事故。Learn how to survive an earthquake.学习如何在地震中生存。He went to an interviewyesterday.他昨天去面试了。She is cutting an onion.她在切洋葱。The old man had an operation on his head.老人头部动了手术。
2) 元音字母U开头的单词,首音节可能发元音或[ju:](半元音j,和辅音一样用a冠词):It's about to rain. You’d better take an umbrella.就要下雨了。你最好带把伞。A university is where you do your degree.大学是你获得学位的地方。Have you ever seena UFO/an unidentified flying object 你见过不明飞行物吗?A calorie is a unitof energy.卡路里是能量的单位。
2) 记住两个h开头却不发音的名词:Half an hourhas passed.半小时过去了。It's an honourto be invited to your dinner.很荣幸被邀请参加你的晚宴。European欧洲人,欧洲的,元音字母e不发音,首音节是[ju:]He is a European, and he has lived in Hangzhou for 10 years.他是欧洲人,在杭州住了10年。
4) 注意辅音字母f, l, m, n, r, s和x的发音都是元音开头:Flower begins with an “f”.花以“f”开头。An x-rayx光片3,如果名词前有形容词做定语修饰,则我们看形容词是辅音还是元音开头。There standsan oak tree in front of the house.房子前面有一棵橡树。An important lessonI've learned from it is never to give up.我从中学到的重要一课是永不放弃。He drives an old car.他开一辆旧车。In those years he was just an unknown pianist.在时的他只是一个默默无闻的钢琴家。An honest man never lies.诚实的人从不说谎。France is a European country.法国是一个欧洲国家。
