A child‘s education has never been about learning information and basic skills only. It has always included teaching the next generation how to become law-abiding citizens. While some people claim that those ex-prisoners are the best teachers to raise the awareness regarding laws， I believe that other measures are equally effective.

　　Obviously， ex-prisoners play a vital role in cutting youth crime. This is because those released prisoners have witnessed the horrors happened in the jail and they may also experience some of them. At the same time， they can share the tears and sorrows they suffered in the jails and the harm they have brought to the victims and their family members. This is more impressivethan the traditional lectures given by professors. By listening to a wide range of real cases in person， young generation will realise the consequence of the irresponsible behaviour deeply and discipline themselves strictly in the future.

　　Nevertheless， I believe other alternatives should be taken into consideration as well. It is common for people to have a fear towards criminals， especially those who have committed violent crimes and therefore face-to-face conversation between the young and people with a criminal record might be inappropriate in some cases. By contrast， policemen normally have a good impression among youngsters and they can become the active voice in reducing juvenile delinquency. Apart from them， parents can certainly be the first to help children learn the differences between right and wrong since they are the people who know their children best in the world.

　　In my opinion， it is the responsibility of every member of a society to help the young generation to become good citizens.
