Hobbies
Different people like doing different things; different people have different hobbies. My brother is fond of collecting stamps. He has got a very good collection and he is proud of it. His stamps can tell you about different people and countries. My brother often says that his hobby is popular with people of all ages.
Collecting stamps is easy and interesting. It is real fun. You begin to learn many facts about history and famous people when you start to collect stamps. At first people collect every kind of stamps. But soon they begin to make special collections. Sometimes they specialize in stamps of one subject only, for example, birds, animals, flowers or sports. This kind of collecting is called thematic. My brother's collection is thematic. His theme is fish.
My best friend, Alice, is a collector too. She is fond of collecting badges. Her collection is thematic. Her theme is sports. She keeps her badges on the wall. When you come into her room you can see them all there.
My grandfather collected coins when he was a boy. Som people collect dolls. My aunt does. When she travels, she always brings home dolls from different countries. Some people collect pictures, cups, toy soldiers, books, pencils and many other things. But collecting things is not the only hobby people have. Some people are fond of travelling or gardening. Very many boys and girls are fond of sport and that is their hobby. My uncle's hobby is taking pictures, and my mother is fond of music. If you have one, what is your hobby. помогите перевести очень срочно нужно. пожалуйста.
