Charity shops are popular in the UK. The first charity shop  _ ( be) opened by Oxfam in 1947. Now there are over 7,000 charity shops in the UK. The shops sell different things from  old book to a famous brand handbag. Here are the reasons why I often go to charity shops.
First, things in charity shops are much  _ (cheap) than those in street stores. People give things to charity shops    free. Most of the things have been used _they are well cleaned and _(repair). So you can buy useful things with less money in charity shop.
Second, people give their own thing to charity shops instead of    (throw) them away. Then other people who need the things buy them. It's good for the environment.
Third,    is for charity work that charity shops are set up. The money earned in charity shops is for people in need,   (especial) for homeless and disabled people after the things in charity shops are sold, the owner will receive a letter telling him about that. That's the main reason why people like charity shops. So I hope there will be more and more charity shops in other__  (place)
