Rob: Right, oh, lovely. That's better. I've had a nice cup of coffee and I'm ready to explain the meaning of today's Authentic Real English. Here you go. When you are on the ball it means you're alert³ and quick to react to things.

Li: 是的。To be on the ball 意思是机警，机灵，往往形容一个人对事物反应迅速。Ball 的单独意思是球。这个短语是不是从体育运动而来？It comes from sports, doesn't it?

Rob: Yes it does. And there is another phrase: 'to keep your eye on the ball' which has a very similar meaning.

Li: I guess we can use it for any situation which is changing quickly so that you need to be focused and sharp. 我们可以用这个短语来表示各种迅速变化的情况，看看你是否精神集中和思维敏捷。
