Every day cars kill or hurt many people on roads. Sometimes the drivers drive too fast or do not drive carefully enough .Some of them       traffic rules and cause accidents.
According to some researchers, it is usually the pedestrians(行人) who cause the accidents. A lot of road users are very     . They walk or run across the roads      the cars. They walk in the roads but not on the walkways. Some do not take the time to        the green lights and simply cross the roads against the red lights.
Many people think accidents often happen in        roads in large cities, but this is not always true.       , Tokyo is one of the world’s largest cities and probably one of the busiest cities. However, there are       accidents to pedestrians. The reason is that the police there are very        and the pedestrians are very careful . Pedestrians never cross the roads against a red light and they     follow the traffic rules.
Do you know alcohol(酒精) is another main cause of traffic accidents? It delays(延缓) people’s response(反应). Those who have drunk alcohol are        in making decision. They need a few more seconds to react. Alcohol drinking is especially dangerous for motor car drivers. It is not only drivers who may have accidents after drinking, drunk pedestrians may put their lives in danger as well.
