序数词的应用
序数词应注意的几点事项:
1. 多位数的基数词变成序数词时,只需将末位基数词变成序数词,前边的基数词不变。如:
forty-two 42 forty-second第42
nine-hundred 900 nine-hundredth第900
2. 当序数词用阿拉伯数字表示时,必须在数字后加上序数词的最后两个字母。如:
21st第21
32nd第32
3. 序数词前一般要用定冠词the,如果序数词前用a或an时,则表示"又一;再一"(没有具体范围的限制)。如:
Though he had failed twice, he wanted to try a third time.
尽管他已失败了两次,他还想再试一次。
The little monkey had had three apples, and he wanted to eat a fourth one.
那只小猴子已经吃了3个苹果,他还想再吃一个。
