Beggars are often seen sitting under blankets as people walk past them in Cambridge’s market center. Some ask passers-by(路人) for change and some just sit and wait to be given money．
To solve the problem of 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. The aim is to encourage people not to give money directly(直接地) to beggars but instead to give generously to the local people who are homeless．
Different people have different opinions. Supporters of this plan think it will be a good way to solve the beggars’ alcohol and drug problems(酗酒和吸毒). But the police don’t support it. They argue that beggars who do not receive cash（现金）may turn to criminality( 犯罪). The homeless charity “Crisis” said the success of any plan will depend on its style. They think that imaginative and positive(积极的) plans can help create local understanding and sympathy（同情心）. Most of the beggars don’t like 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 a big role in working out this problem. Training beggars to work and helping them to find jobs is a good way. This is true for developing countries where many simple jobs exist. People should also be educated to see beggars not as dirty and dangerous, but as people who need understanding and help.
