In my village a lot of children have left school for many different reason. Some families are so poor to send their children to school,but their kids have to earn money to support their families. There are also many parents which do not think it useful to send their children to school. They prefer to have their children do something else rather than to let them go to school．I feel worried this．I think every children should have the opportunity to receive education．And it is necessary of us to care about the children，because one day they will play a important part in the construction of our country．So ways must be found to stop children from leave off their studies．
