On the morning of April 29, 2007, from 10:00 to 11:00, hundreds of millions of students from primary, middle schools and universities all over China joined in a national student sports program. Eleven million students in Jiangsu took an active part in this program.The Ministry of Education calls on students to exercise for an hour every day, in the hope that they will have good health to work fifty years and enjoy the whole life.Personally, I think it a good idea for us senior 3 students to have daily exercise. Although we take an hour a day for exercise, it is well worth it. Taking exercise helps us build up our body and keep a clear mind. Therefore, we can work more efficiently.Thank you!
