冠词是置于名词之前,说明名词所表示的人或事物的一种虚词。冠词不能离开名词而单独存在。

冠词的分类:定冠词、不定冠词和零冠词 

(1) 定冠词(the):the通常有明确的所指,即以说话人和听话人已知的人或事物为前提,可与单数可数名词、复数可数名词或不可数名词放在一起使用。
(2) 不定冠词(a\an):a\an有不确定的意义,即所说的人或事物对听者或读者来说可能是不知道的,其中an放在以元音开头的名词前面,如an apple。不定冠词只能与单数可数名词结合,基本含义有“该类中的一例”、“只有一个”、“每一个”等。
(3) 零冠词:即不使用冠词。一般来说,在复数可数名词、不可数名词或专有名词前不使用冠词。

基数词的构成方法:

2002: two thousand and two

977, 102: nine hundred and seventy-seven million

 

★基数词的用法要点

There are nine thousand, seven hundred and twenty-eight books in the library.

这个图书馆里有9, 728本书。 

There are hundreds of people in the hall.

第1--第3:

one → first; two → second(2nd); three→ third(3rd) 

 

第4--第19: 

一般都是“基数词+th”结构,但fifth, eighth, ninth和twelfth结构特殊,我们要加以留意。 

 

第20-第几十几:

整数第几十的形式由其对应的基数词改结尾字母y为i,再加-eth构成。如:

twenty—twentieth

 

第一百以上的多位序数词:

由基数词的形式变结尾部分为序数词形式来表达。如:

one hundred and twenty-first

(序数词可以缩写成“数字+序数词的后两个字母”形式。

 

★⑵序数词的用法要点:

①序数词一般与定冠词the连用。有时前面也可以加不定冠词,表示“再一; 又一”。例:

This is the first time that I have been in China.   

这是我第一次来到中国。 

We'll go over it a second time.

我们得再念第二遍。 

 

②当序数词的前面有物主代词等限定词修饰时 不用任何冠词。例: 

Today is the baby's first birthday. 

今天是这个婴儿的第一个生日。 

 

③序数词在句中作副词时,不用任何冠词。例: 

Linda always comes first in English.

琳达英语总是第一名。 

 

注意:基数词也可以表示顺序。只需要将基数词放在它所修饰的名词之后即可,不需要添加定冠词。
