People may have many different types of hobbies during the lifetime. When we are very young, we spend most of the time playing with toy cars. We may enjoy playing a sandbox or building with wooden blocks(积木).
When we get older, we start our first real hobbies. Some kids go out for a sport like football or skating. These new interests can be quite time-consuming and most children spend a lot of time on them. Some children might get interested in some quiet activities like reading, painting or stamp collecting. Others might enjoy playing an instrument like the piano or the violin.
As we get older, our hobbies might change or go on. Some people might spend their whole life on stamp collecting. Other people might change their interests every year. Some people are lucky because they have found jobs that are similar to their hobbies, like a person who loves teaching and becomes a teacher.
