The world is becoming better and better.But there are still some problems.There are still many homeless people、child laborers and cruel wars.Many people die of hunger or diseases.Many children have to work when you are still very young.There are cruel wars between some countries.
So,we should try our best to provide warm houses for those homeless people,let them enjoy good community services,receive good education and live a happy life.
世界正变得越来越好.但还存在一些问题,还有很多人无家可归；还有很多童工,战争时而爆发.很多人因为饥饿或疾病而死去,很多儿童还很小就不得不去工作,一些国家间还有战争.
所以,我们要尽一切努力给那些无家可归的人们提供房子,让他们能享受到良好的社区服务,接受良好的教育,过上幸福的生活.
