Almost everyone has some kinds of hobbies : it may be something from collecting (邮票) to making (模型)planes. Some hobbies are very expensive, but the others don't cost anything at all. Some collections are worth much money and the others are (有价值的)only to their owners.
I know a man who has a (硬币) collection worth several thousand (美元). A short time ago, he bought a rare (罕见的) fifty-cent piece which cost him $ 250!He was very happy about this collection and thought the price was all right. On the other hand, my ten-year-old brother collects (扇子). He collected them at an early age. He has almost 600 of them and puts them on the (架子)in the bedroom, but l wonder if they are worth any money. However, to my brother they are quite important. Nothing else makes him happier than to find a new one for his collection.
That's what a hobby means, I think. It is (某事) we like to do in our free time (只是)for the fun of it. The (价值)in dollars is not important, but the pleasure it gives us.
