I and many other people in Britain love charity (慈善) shops because we can find them on every street. The charity shops sell all kinds of things and they are very cheap.

The first charity shop was opened by Oxfam in 1947. Now there are over 7,000 charity shops in the UK. My favourite charity shop in my hometown is the Red Cross Shop. There I always find children's books, all 10 to 20 pence each. They are really cheap.

Most of the shop workers in charity shops are volunteers (志愿者), ________ each shop has a manager and he gets some money. Every morning you see bags of things outside the shops. Some people bring and put them there without waiting for thanks. In fact, over 90% of the things in charity shops are from kind people.

All the money the shops get goes to charity work. Charity shops raise more than 110 million pounds every year. The money is for sick and poor children, homeless and disabled people, and many others. In a charity shop you can get cheap but nice things. You might even feel special while shopping.
