1 . Two years ago, my son said he wanted to learn how to play the piano. I     1    (buy) him a piano and employed a tutor to teach him.     2    ,half a year later, he lost his interest in the piano and no longer wanted to play it. My husband and I really didn't want him to give up, we insisted that he     3    (practice) it every night. However, he didn't like that idea and often played the piano     4    (unwilling). We couldn't think of a good way to persuade him.

One night, an old man     5    lives downstairs came to us,     6    a box of candies in his hand. To our surprise, he said he wanted to thank my son. He went to my son and handed him     7    gift, saying, “I really want to thank you. Because of you, my wife and I can hear beautiful music every night. It     8     (bring) us a lot of fun.” My son looked     9    (surprise) at first, and then he became very happy.

    10     (know) some people are enjoying his music made him want to play the piano well. From then on, he sat in front of the piano and practiced hard every night.
