清理赛场用英语怎么说

"Cleaning the playing field" is the English way to describe the action of cleaning the place where a sports game or event is being held.
The phrase "playing field" refers to the area where a sport is played. It is a metaphor, as the field is where the game is played, just as a battlefield is where a battle is fought.
Here are some example sentences using this phrase:
"The grounds crew is responsible for cleaning the playing field before and after every game."
"Make sure to sweep the playing field before the match starts."
"The playing field needs to be cleared of debris before the game can begin."
In Chinese, this phrase can be translated as "清理比赛场地" or "打扫比赛场地."
