a, an, the的用法讲解及练习
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),另一种是不定冠词(the Indefinite Article),还有一种是零冠词(Zero Article)。
健康指数an, a是不定冠词,仅用在单数可数名词前面,表示“一”的意义,但不强调数目观念。a用在以辅音(指辅音音素)开头的词前, an用在以元音(指元素音素)开头的词前。
the是定冠词,修饰特指名词 翻译成“这个”。如果泛指某物,用a,/an,具体指某物的话,用the.
注意:
(1)当我们使用an时,条件有三:
①这个名词的读音必须是以元音音素开头--即它的 音标的第一个音素是元音,而不是说它是以元音字母开头。
②它必须是个可数名词。
③它还必须是个单数名词。我们常常见到这类用法:
        an university 一所大学              an hour 一个小时
        an orange 一只桔子                an engineer 一位工程师
        an ordinary man一个普通人          an honest person一位诚实的人
(2)定冠词在句子中,既可以用于可数名词前,也可以用于不可数名词前;既用在可数名词的单数形式前,也用在可数名词的复数形式前。从表达意义上讲,它既可表达this, that之意义,也可表达these, those之意义。
一.不定冠词的用法:
1.用于可数名词单数前,表示某一类人或事物。
This is a ruler.
He’s a student.
2.指人或事物,但不具体说明何人或何物。
There are seven days in a week.
We have three meals a day.
