　　Parasites of Big Cities
　　Nowadays there are many beggars in big cities, who are called “parasites of big cities”. Some are begging something to eat for survival, while most of them are professional beggars according to the survey. In addition to plain beggars in rags, there are many disabled beggars and begging families with the children as the leading character. Besides, in recent years, student beggars have appeared.
　　No doubt, these “parasites of big cities” have brought great bad effects. On the one hand, their asking a reward without labor is a burden on the society and influences the city image. On the other hand, many pretended beggars cheat people’s sympathy by fake stories and experiences, which is very harmful to society.
　　Considering the bad effects of “parasites of big cities”, it is high time for us to take effective measures to solve the problem. Firstly, the government should pay more attention to these beggars and resettle them in a reasonable way. Secondly, education and training should be given to these beggars to help them learn how to support themselves. Besides, people should be more cautious in providing helps to the beggars and leave no chance to those cheaters.
