四、下面是根据一个饼状图(pie chart)写的范文

Road Accidents in China

It is evident from the pie chart that there are three major sources of road accidents in China. Motor vehicle accidents are the most common as they account for 48.8% of all accidents. Bicycle accidents are also common amounting to 36%. The third type of accidents，which makes up only 10%，is related to pedestrians.

Some possible causes of road accidents are as follows. Most of the road accidents caused by motor vehicles usually result from drunk driving and speeding. Cyclists who run a red light are also likely to be injured or killed by motor vehicles. With no traffic rules to obey，quite a few pedestrians rush across a street whenever and wherever they want. Poor road conditions and bad weather can trigger some road accidents，too.

To minimize traffic accidents，we must devise some effective measures. For example，any violators of traffic regulations，such as drunk drivers and speeders，should be severely punished with heavy fines，revocation(吊销) of driver's license for good，and even imprisonment. Meanwhile，cyclists should use hand signals to warn other road users of their intentions and pedestrians should be encouraged to cross a street via an overpass or an underpass. To sum up，if we all contribute to traffic safety，the number of traffic accidents will be greatly reduced.
