| Beggars are often seen sitting by the side of a street with heads bowed as people pass them by. Some ask people passing by for a small amount of money and some just sit and wait to be given money. A few use aggressive(侵略性的) behaviour to earn money. To solve the problem of aggressive begging, an "alternative giving" plan has been suggested. Ten blue money boxes will be placed in busy places such as the market and the railway station. It is aimed at encouraging people not to give money directly to beggars but instead to give money generously to local homeless causes. Supporters of this plan think it will be an effective way to solve the beggars' alcohol and drug problems. But the police are against the plan. They argue that beggars who do not receive cash may commit crimes to satisfy their own needs. The homeless. charity (慈善机构) says that the success of any plan will depend on its style. They think that in a certain degree imaginative and positive plans may help to create local understanding and sympathy (同情). Most of the beggars dislike the plan because they think they will not get enough money from the boxes for their showers, food and clothes. Begging is a big social problem both in developing and developed countries. Governments must play an active part in solving this problem. Training beggars to work and helping them to find appropriate jobs is one choice. This is especially true for developing countries where many low-skill jobs exist. The public should also be educated to see a beggar not as dirty and dangerous, but as people who need understanding and help. | |||||||||
