Dear__classmates，
Good__afternoon!
Today__is__December__8th.__The__college__entrance__exams__are__really__around__the__corner__now．As time becomes limited and schoolwork begins to pile up，many students start to feel much stressed—some find themselves very unenergetic and not able to concentrate; some even fall asleep in class.What should we do to avoid those problems?
First of all，physical exercise is the best way to reduce stress and help people relax.Therefore it is highly advisable that we have some physical exercise after some hours of mental exercise.Second，having a proper study plan is of great importance too，since it can remind us what to do and is helpful for us to do our work more efficiently.Last but not least，we should pay special attention to our diet as well. Anyway，a balanced and nutritious diet can keep a busy mind smart and energetic.
Only if we can do these three things mentioned above will we make our time of study and preparation work enjoyable，efficient and fruitful.
Thank you.
