     I love charity(慈善)  shops and so do lots of other people in Britain because you find quite a few of

them on every high street.The charity shop is a British institution, selling everything from

clothes to electric goods , all  at very good  prices. You  can  get things you won't find in the shops any

more. The thing I like best about them is that your money is going to a good cause and not into the

pockets of profit-driven companies, and you are not damaging the planet , but finding a new home for

unwanted goods.

     The first charity shop was opened in 1947 by Oxfam. The famous charity's appeal to aid postwar

Greece had been so successful it had been flooded with donations (捐赠物). They decided to set up

a shop to sell some of these donations to raise money for that appeal. Now there are over 7, 000 charity

shops in the UK. My favourite charity shop in my hometown is the Red Cross shop, where I always find

children's books, all 10 or 20 pence each.

      Most of the people working in the charity shops are volunteers , although there is often a manager

who gets paid. Over 90% of the goods in the charity shops are donated by the public. Every moming you

see bags of unwanted items outside the front of shops, although they don't encourage this, rather ask

people to bring things in when the shop is open.

      The shops have very low running costs :  all profits go to charity work .  Charity  shops  raise  more

than ￡110  million  a year ,funding (资助) medical research, overseas aid, supporting sick and poor

children , homeless and disabled people , and much more. What better

place to spend your money? You get something special for a very good price and a good moral sense.

You provide funds to a good cause and tread lightly on the environment.
