Yesterday, after school, Yuhai and Liufei were heading home by bikes, talking and laughing happily. An accident happens to the two students on their way home. Seen a passing bus, they started to chase one and thought it was great fun. Unfortunate, the bus stopped the moment the traffic light turned red. The two students were very close to the bus that they were not able to stop bikes in time. As result, they were knocking off the bikes, one with his left arm broken and the other with his leg hurting. Therefore, it’s important to keep in mind that although roads are countless, but safety is foremost.
