急迫的a. u_______

Time is dangerous.If you don’t control it，it will control you.If you don't make it work for you，it will work against you.You must become the master of time，not the servant.

Study hard and play hard is an old proverb，but it still makes sense.You have plenty of time for classes，study and play if you use your time properly.It is not how much time you allocate for study that counts but how much you learn when you do study.
