Now,the health of students worries many people.It is very common that what the students eat is good,but they cannot run fast and jump high.And About two-third students become short sighted.For this problem,the Ministry of Education calls on students to take an active part in the national student sports program,which requires students to take exercise one hour per day,to live a healthy life for 50 years and to live happily for all life.In my opinion ,this activity will benefit both students and society.You know,students are the future of our nation.They should have a strong body.On the other hand,taking exercise will do good th students health and help them to raise the studying efficiency
