如果第一遍没听清,可以说I'm sorry,could you please repeat that question?或I'm sorry I think I missed the point,could you please...
或者是其他委婉的请他重复一下
如果只是个别词的话,你可以说I'm sorry I missed the word"..."请他解释词语
没关系,评委都会很友好的
如果实在不懂而且解释了也不清楚,那就只好I'm sorry I don't understand.
或者是Would you please speak in another way?
不过好像用pardon问不是很好
加油哦,祝你比赛成功!
