this is the first public performance of the play.
这是该剧的首次公演。
【注意】在谈到编号的东西时，通常用序数词。例如：
the first part第一部分
the twenty-third section第二十三章
也可以用基数词来表示(这时名词要放在基数词之前，名词和基数词都要大写)：
the first part第一部分→part one
the twenty-third section第二十三章→section twenty-third
如果数字较长，序数词总避免使用，例如：
第201号房间：room 201
第319面：page 319
第一拖拉机厂：the number i tractor works
第六号车厢：carriage no.6
第七路公共汽车：bus number seven
