阅读理解。

     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 anymore. 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 morning 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.
