【考点】应用文；日常生活．

【答案】Exercising is important!  Recently，we have done a survey about students' exercising.According to the survey，32% of the students spend over one hour every day doing exercise，while 68% of them spend less than one hour.The reasons are as follows：Firstly，46% of them have too much homework，so they have no time to do exercise.Secondly，29% of them are not good at exercise.Thirdly，25% of them are not interested in it.
  As we all know，exercising is good for our health，which keeps our minds sharp and makes us confident and happy.
   In my opinion，we should keep a balance between our study and exercising.Besides，we should develop a good habit of doing exercise.
