| 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. | ||||
