完形填空 When I was young, I liked to play jokes on people I knew, especially on my parents and friends. One day my mother was 1 and I was playing with my younger brother Tony. Suddenly I ran to my mother and said, “Tony fell from the open window!” She was very 2 and ran out of the kitchen. Then I said, “Don’t worry. I’m just 3 .” And my mother shouted at me, “If you do it 4 , I’ll hit you.” One day I went swimming with my 5 in the sea. I wanted to play a joke on them. In the beginning, I went swimming 6 , and I called out, “Help!” All my friends came to help me, only to 7 that I was joking. But the next time I wasn’t joking. I was so 8 that I swam in deep water. I tried my best to call my friends for help, but this time nobody came to help me. 9 , they found I was telling the truth. They came and saved my life. They took me to the hospital. This is the best 10 in my life. From then on, I haven’t joked on anyone.
