英语中名词前面加不加冠词
不定冠词a and an
" a " and " an " 用在不确定的单数名词前, 用来指一个群体中的任何一个。
For example:
-
"My daughter really wants a dog for Christmas."
-
"Somebody call a policeman!"
-
"When I was at the zoo, I saw an elephant!"
-
I am a teacher.
-
Brian is an Irishman.
-
Seiko is a practicing Buddhist.
用a还是an取决于它们后面的词的首音节是元音还是辅音（切记不是字母）：
-
a 辅音开头的名词: a boy; a car; a bike; a zoo; a dog
-
an 元音开头的名词: an elephant; an egg; an apple; an idiot; an orphan
-
a 元音字母u,但发/ ju:/音 a user , a university; a unicycle
-
an 辅音字母h开头，但h不发音: an hour an honor
-
a nouns starting with a pronounced "h": a horse
如果名词前有形容词修饰，用a还是an由形容词的首音节决定，规则同上:
-
a broken egg
-
an unusual problem
-
a European country (元音字母e不发音，所以首音节是/ju:/)
