初中英語語法大全：冠詞

冠詞是虛詞，本身不能單獨使用，也沒有詞義，它用在名詞的前面幫助指明名詞的含義。冠詞分為不定冠詞a(an)和定冠詞the兩種。不定冠詞僅用在單數(shù)可數(shù)名詞前面，表示“一”的意義，但不強調(diào)數(shù)目觀念，只表示名詞為不特定者。定冠詞則表示名詞為特定者，表示“這”、“那”、“這些”、“那些”的意思，在可數(shù)的單復數(shù)名詞或不可數(shù)名詞前面都可以用。

I 不定冠詞

We need an apple and a knife.

我們需要一個蘋果和一把刀子。

1.a和an的區(qū)別

不定冠詞有a[+]和an[+Q]兩種形式，a用于輔音(不是輔音字母)開頭的詞前。an用于元音(不是元音字母)開頭的詞前。

a boy, a university, a European country

u是元音字母，但發(fā)音是[U(]，是輔音。

an hour ，an honor ，an island

h是輔音字母，但它不發(fā)音，它的音標是是元音。

an elephant， an umbrella， an egg
