文档介绍：不定冠词的用法
Unit 1 Making friends

冠词是虚词,本身不能单独使用,也没有词义,它用在名词的前面,帮助指明名词的含义。英语中的冠词有三种,一种是定冠词(the Definite Article : the ),另一种是不定冠词(the Indefinite Article: a和an ),还有一种是零冠词(Zero Article)。不定冠词用在单数名词前,表示泛指;定冠词用在名词前,表示特指。
如:
a book an egg the elephant
一本书一个鸡蛋那只象
Find ‘a/an’
Find ‘a/an’ in the passage on page 3 and try to work out the rule.
Grammar
:
发元音的单词前用‘an’。
发辅音的单词前用‘a’。
(不定冠词)
2. 不定冠词表示泛指,意思是“一”。
一般情况下,就是元音字母前用an,辅音字母前用a,26个字母中,a、e、i、o、u为元音字母,也就是这几个字母开头的单词前一般用an,除了这5个元音字母,其余的为辅音字母,前面一般情况用a.
1. __a___ useful book虽然首字母是元音字母,但发音却辅音
2. ___an__ hour首字母是元音字母,但发音却以辅音开头
3. ___an__ honest boy首字母是元音字母,但发音却以辅音开头
4. ___a__ university虽然首字母是元音字母,但发音却辅音
5. ___a__ uniform虽然首字母是元音字母,但发音却辅音
6. ___an__ European country首字母是元音字母,但发音却以辅音开头
7. ___an__ ‘s’ in ‘student’
8. ____a_ unit虽然首字母是元音字母,但发音却辅音
