I think that children nowadays are playing less and less sport because they are busy with their studies.For many parents,the desire for their children to get in the groove is quite common.They may hope that their children can achieve success in a competitive society,driven by their concern and love for their children's future,which leads them to place great importance on academic performance.They may arrange various tutoring classes for their children due to placing great importance on their academic performance.The heavy workload of homework from school and different tutoring classes has taken up most of the students' time and spirit so they have to forgive the leisure time in order to finish the unreasonable workload.Then,students are playing less and less sport.Actually parents can focus more on the emotional and physical health of their children,encouraging them to play more sport.
