到了比赛那天的英语怎么说

如果您要描述比赛那天的情况，可以说 "It's the day of the competition" 或 "It's competition day"。
"It's the day of the competition" 的来源是比赛那天是指比赛预定举行的日子。可以用一些例句来说明：
"I can't wait for the competition day. I've been training for this for months."
"Are you ready for the competition day? I heard it's going to be a tough one."
"It's finally here! The competition day is finally upon us."
这些句子的中文翻译分别是：
"我迫不及待地想要等到比赛那天。我已经为这场比赛训练了好几个月了。"
"你准备好了吗？我听说那天比赛会很难。"
"终于到了！比赛那天终于来临了。"
