| It was Mother's Day. I was so busy with my work that I couldn't 1 back home. When I passed by a 2 shop, a(n) 3 came to my mind, "I'll send Mum some roses." While I was 4 my flowers, a young man went inside. "How many roses can I get 5 only five dollars, Madam?" he asked. The assistant was trying to tell him roses were as 6 as forty dollars a dozen - maybe he would be happy with carnations(康乃馨). "No, I 7 have red roses." he said, "my mum was 8 ill last year and I didn't spend much time with her. Now I want to get something special, roses, as rose is her ." After hearing it, I said I would pay 10 of the money for the young man. 11 by both of us, the assistant said, "Well, lovely young man, thirty dollars a dozen, only for you." Taking the roses, the young man almost jumped into the 12 and ran out of the shop. It was 13 worth twenty-five dollars I paid to see the exciting 15 . Then I paid for my dozen of roses and told the assistant to 14 them to my mother. As I walked out, I felt 16 . Suddenly I saw the young man crossing the street and going into a park. But soon I 17 it was not a park 18 a cemetery(公墓). Crying, the young man carefully 19 the roses, "Mum, why didn't I tell you how much I loved you? God, please help me find my mum and tell her I love her." Seeing this, I turned and quickly walked to the 20 . I would take the flowers home myself. | |||
