the序数词后通常加 形容词最高级。例如：
1. She is the first one to arrive.
2. This is the second time I have visited this city.
3. They are the best team in the league.
需要注意的是，当序数词为first时，有时可以省略the，例如：He was the first one to come here.
此外，the序数词后也可以加名词、动名词或介词短语，例如：
1. The second question is the most difficult one.
2. The first coming of spring is always beautiful.
3. The second tallest person in our class is also very tall.
希望这些信息对你有所帮助。
