If my dream could come true instantly ,I would like them to be as follows:
First of all .There are no wars and no conflicts in the world ,People of different national and race can coexist peacefully and be friends each other ,There is no such pharse as racial discrimination .
second ,human beings can conquer all diseases for good ,at least fatal ones ,Then people would not suffer from cancers ,ADIS or heart disease ,no family would be heart -broken for losing its dear ones ,every girl and boy can get marry with her /his best lover.
Third the welfare system is more mature ,I wish there were numerous spacious houses to shelter the homeless ,And what is more people do not have to worry about making a living ,bring up children and having them well-education and whom to depend on them when they are aged.
