So，exam time is around the corner.Have you done the necessary work to get good marks？ （1）Sleeping with the textbook under the pillow （枕頭） doesn't work. Knowledge won't come into your brain magically when you sleep.The best way is to space your practice out，rather than fill it all together. （2）不要只是依靠你的記憶力。You can start by reading a textbook with your favourite pens and colors，and then write down the important ideas on small cards.While doing so，you actually try to test yourselves on these small cards.
   Good reviews will give you confidence，（3）but if you are still worried，it's not harmful to follow some special customs. In China，when the kid takes the big exam，mum will always wear a Qipao.Qi，means "flag".It's the first character in an idiom （成語） that means "to win victory upon raising the flag"，and which has been suitable to wish students sweeping success on their exams.
   In Japan，（4）對學生們而言，在考試前吃一種特別的安慰食物似乎是一種傳統(tǒng)。The comfort food is made up of a bowl of egg and pork pieces named Katsudon.The name of the dish makes people think of the word "katsu"，meaning "winning".（5）For some students is South Korea，the key to success is not washing their hair before an exam， because they believe they could wash all the knowledge out of their heads.And in different parts of the world，there are always those who believe in their "lucky numbers".
   The bottom line is that you need to study，eat a good meal，sleep well on the eve of the test，and believe that your efforts will pay off.
