在球上是什么意思呢？起源于什么领域 如何使用？
看一个对话例子：
A: My parents frequently urge me to get a stable job, like civil servant. I don't understand. I like free life, and I don't want to be fixed on one place.
B: With a job, if you aren't quite on the ball one day, you still get paid.
A: Money will never be problem for me .
