序数词的功能:序数词在句中可作主语、宾语、定语和表语。

1、The second is what I really need. 第二个是我真正需要的。(作主语)

2、He chooses the second. 他挑选了第二个。(作宾语)

3、We are to carry out the first plan. 我们将执行第一个计划。(作定语)

4、She is the second in our class.在我们班她是第二名。(作表语)

注:序数词在使用时,通常前面要加定冠词the;但是如果序数词前出现不定冠词a或an时,则表示“再......”,“又......”。

5、We'll go over it a second time. 我们再念第二遍。

6、We've tried it three times.Must we try it a fourth time? 我们已经试过三遍了,还必须再试一次(第四次)吗?
