From Monday until Friday, most people are busy working or studying. But in the evening and on weekends they are free to relax and  1  themselves. Some watch television  2  go to the cinema, others take part in sports. It  3  on individual（个人的） interests. There are many different  4  to spend our  5  time.
  Almost everyone  6  some kind of hobby . It may be  7  from collecting stamps to  8  model airplanes. Some hobbies are very expensive. But others are valuable  9  to their owners.
  I know a man who has a  10  collection  11 several thousand dollars. A short time ago, he bought a  12  fifty cent piece worth 250! He was very  13 about his purchase（购买物）and thought the price was reasonable. On the other hand, My youngest brother  14  match boxes. He has almost 600 of them but I doubt if they are worth  15  money. However, to  16  they are extremely valuable . Nothing  17  him happier than to find a new match box for his collection.
  That's what a hobby  18  , I guess. It is something we like to do  19  our spare time simply for the  20  of it . The value in dollars is not important, but the pleasure it gives is.
