both cultural barriers and national boundaries.

, in my opinion, these

games

have little value to them and produce a lot of harmful effects on their physical and mental development.

games

computer

a recent survey, the obesity rate among adolescents aged between 13 and 19 is soaring in industrialised nations

as well as

are indeed valueless and may exert negative impacts on the development of young offspring.

Therefore

, it is high time that parents and schools should be alert to the problem, and restrict children's access to those
