核心句型：
If you hope to keep your job, you'd better get on the ball.
如果你不想丟工作，就最好用點心。
get on the ball直譯過來就是：“把球搶到手”，這個短語的正確意思是：“工作出色，用心工作”。因此，當美國人說"If you hope to keep your job, you'd better get on the ball."時，他/她要表達的意思就是"If you want to have this job, you must try your best to do it."、"If you don't want to lose your job, you have to work hard."。
