A terrible storm took place in a Friday night. The wind was so strong that many trees were brought down. It is eleven o’clock. Li Ming, one of my best friend, was still not back and his parents were very anxious about them. Half an hour late, the wind stopped，but it was still rainning hardly. Li Ming’s parents were about to look for him then he came home. Li Ming explained that the storm pushed over big trees as well as electricity poles, blocked the roads and that the bridge had washed away by the floods. Therefore, Lei Ming and his classmates had to find another way back. What was even more worse, one of his classmates had a arm hurt. So they took him to the hospital.
