     I like collecting stamps.  When I was a baby,  my mother began to collect stamps for me.  Of course, 
she did not let me    l    the stamps until I was old enough not to spoil them.  I remember that it was   2 
my fifteenth birthday that she   3   put them into my hands.  They were in four thick books and    4    
then I have added three times more, so now I have a   5   collection than any of my friends.  How do
I get my stamps?I have  never bought even one stamp from a shop so my collection has cost me   6 . 
      My father works in a big office.  Sometimes he   7    me home stamps from many countries.  I have
friends both here and in other countries.  They    8   me a lot of wonderful stamps every year.  Since I
am   9   for my living,I do not have as much time as before to    10   my stamps.  But in the evening, I
sometimes bring out the books and   11  the stamps inthem.   12  stamp has a story to tell me   13  
far countries and strange people.  I see pictures of men and women,  birds and animals that I have never
seen.  Kings and famous, people   14    before my eyes,  and in this way I have a   15   at home. 
      Stamp collecting  is a better way to learn history, geography and languages.
