Bob was only seven years old. One night Bob was at home  while his parents were out for a party. He had often stayed alone before, so he wasn't afraid. As he waited for his parents to  home, he watched a film on TV. His eyes became heavier and heavier as time  by.

      Suddenly Bob's eyes opened wide-what was the  in the next room? Bob heard the window being opened slowly. For a minute, Bob was so  that he could not move, and his body felt like ice. He knew that he couldn't lose his head (惊慌失措) and began to think of the things he could do. Again he heard the sound of someone trying to climb into his home  the window.

      Bob's drums were standing in the corner near the TV. "Wait,  there is something I can do," thought Bob. He  on his drums as hard as he could. The sound was so terrible that Bob  even himself. He also surprised the man in the window, who  away as fast as possible. How clever he was!
