A hobby is something you like doing in your free time, such as reading, listening to music, making something, growing, collecting different things, etc. Different people like doing different things, so we can say that people have different hobbies. “Tastes differ,” says the proverb.

My friends are fond of collecting different things: dolls, postcards, coins and stamps. My friend Ann started collecting dolls when her aunt gave her a china doll. It’s the oldest one she has in her collection. It was made in France a hundred years ago. Her other dolls are modern. She has twenty-one in her collection.

They are different: they are made of plastic, wood and cloth. The smallest one is 1 cm tall. The most beautiful are from Germany and Britain, and they are dressed in regional costumes. She also has a lovely wooden one from Russia. My friend is proud of her collection. She likes to show all her dolls to her friends and to tell interesting things about them.

My other friend Mike has hundreds of postcards and they are all fascinating. At first he started collecting all sorts, from all over the world. That was too complicated, so now he collects local ones. They describe the history of our city during the last hundred years. One of my classmates collects coins because he likes the history they record. He has a special catalogue where he writes everything he knows about his coins. It’s a very interesting hobby.

My brother is fond of collecting stamps. And I think they’re the best things to collect. Collectors usually have a theme: stamps from one country, stamps about space, animals, ships, etc. My brother’s theme is famous people. He has a special notebook where he writes down everything he knows about famous people from his collection. Of course, collecting can cost you a lot of money if you buy an old thing. But my friends swap with one another.

Write true, false, doesn’t say:

1. Ann started collecting dolls when her mum gave her a china doll.



2. One of the writer’s classmates collects coins because he likes the history they record.



3. The writer’s brother lives in London.
