基数词和序数词的用法
1. 基数词的用法
(1) 作定语。如:

Ten people will come to the party. 十个人要来参加聚会。
(2) 作主语。如:
It is said that thirteen is an unlucky number.
据说13是个不吉利的数字。
Three of them will play football. 他们中有三人要去踢足球。
(3) 作宾语。如:
It is worth three hundred. 这件东西值300。
The city has a population of three million.
这个城市有三百万人口。
(4) 作表语。如:
I am eighteen. 我18岁。
Two and two is four. 二加二等于四。
(5) 作同位语。如:
Are you two coming? 你们俩来吗?
They ten will go abroad. 他们十个人将出国。
2. 序数词表示法
(1)
有时序数词前面可加不定冠词来表示“再一”,“又一”这样的意思。如:
We’ll have to do it again. 我们得重做一次。
Shall I ask him a third time? 还要再问他一次吗?
When Nash sat down, a fourth man rose to speak.
纳什坐下后,第四个人又起来发言。
(2) 序数词的主要作用
作主语。如:
The first day of May is International Labor
Day.五月一日是国际劳动节。
作表语。作表语时,序数词前的定冠词往往省去。如:
Lind was second last year. 林德去年是第二。
作宾语。如:
He was among the first to arrive. 他是首批到达的人员之一。
作定语。如:
May is the fifth month of the year. 五月是一年中的第五个月。
作同位语。如:
Who is the woman, the second in the second line?
在第二列第二个的那个妇女是谁?
但要注意:在很多情况下,我们可以用基数词代替序数词来表示顺序。如:
the second part = Part two (第二部分)
the first chapter = Chapter one (第一章)
the fourth section = Section four (第四节)
