序数词的用法 ①作主语 e.g. The third of the month was a holiday. ②作表语 e.g. Who was the third? ③作定语 e.g. We live on the fifth floor. ④作宾语 e.g. I was among the first to learn of this. ⑤作同位语 e.g. Who is that man, the first in the front row? ⑥作状语 e.g. When did you first meet him? 注:有时序数词并不指顺序,而是表示"再一,又一"的意思。此时序数词前要加不定冠词 e.g. I want to make a second try.
