| Herb was at home alone one night while his parents were out in the evening. He had often stayed alone before, so he wasn't 1 . As he waited for his parents to return home, he watched the latest films on TV. 2 became heavier and heavier as the time passed. Suddenly Herb's eyes opened wide. What was that 3 in the next room? Herb heard the window slowly being inched (一点一点地) open. For a minute Herb was so frightened that he could not 4 , and his body felt like ice. He knew that he mustn't lose his 5 and began to think of the things he could do. He couldn't 6 the telephone without passing the window where he had heard the noise. Again he heard the sound of someone trying to 7 into his room through the windows. Herb's drums were standing near the TV. "Wait, maybe there is something I can do." thought Herb. He picked up the drumsticks and beat on the drums as 8 as he could. The commotion (骚动) was so terrible that Herb surprised 9 himself. He also surprised the person 10 the window, who ran away as fast as possible. | ||||
