After a plane crashed in South China on March 21st, rescued workers managed to find two black boxes. The black boxes may provide the key to understand why the plane crashed. When black boxes are recovered in well condition, investigators (调查员) can analyze and produce a report on their content for about three months, but it can take much longer when they are damaged, said Li Xiaojin, a professor from the Civil Aviation University of China. One of the black box from the crashed Flight MU5735 was found on March 23rd. The second black box is recovered on March 27th. The black boxes are not black. Therefore, they are painted bright orange to aid in their recovery after accidents. They are usually placed in the tail of a plane, which they are more likely to survive a crash. It can work for 30 days without any electricity.

On my way to home yesterday afternoon, I happened to witness a traffic accident. When an old woman was crossed the road, she was knocked down by a boy riding bike. The boy was such frightened that he stood still at the scene but didn’t know what to do. I quickly went up and saw the old woman lie on the ground, making crying because of pain. I stopped a taxi and told the driver that had happened. The driver drove them to the nearest hospital at once. To our relieve, we were told that the old woman wasn’t injured seriously after she was examined carefully. The boy was deep grateful for our help.
Last Saturday our class went hiking in a countryside. We meet at our school gate and set off at 8:00 am. On the way, we were singing and laughing happily while a girl suddenly fell into a deep hole.She felt so frightening and even burst into tears. One of my classmate found a long rope and we got him out. Fortunately, she didn’t suffer seriously injuries, but it seemed that her ankle slightly twisted. We managed to sending her to the nearest hospital. It is an experience we’ll never forget it, though we didn’t enjoy ourselves very much that day.
