阅读下面的短文,然后按照要求写一篇150词左右的英语短文。

On May 7, nineteen-year-old Hu Bin, after drinking, knocked a man to death when he was driving his sports car at an extremely fast pace between 84.1 k/h to 101.2 k/h. Hu was sentenced into prison for three years, according to the final judgment. Out of a hope for better traffic regulation and more drivers with loving hearts, Hangzhou City has since set up several special zebra crossings, which are wider, color-changed, and feature loving hearts wrapped up in the middle.

On August 4, a sixteen-year-old girl was crashed into by a black Porsche Cayenne and dead while crossing the street in Hangzhou City. The driver, 29-year-old Wei Zhigang, and his fiancé, who was also in the car when the accident took place, were both found drunk. According to witnesses, the Porsche Cayenne was speeding at more than 80 kilometers per hour at the time. The victim, Ma Fangfang, is a waitress in a restaurant in Hangzhou. She was walking on the zebra crossing when the Porsche Cayenne violently charged toward her and knocked her away. Wei Zhigang, the driver of the Porsche Cayenne, together with his fiancé, was detained and investigated by the Public Security Organ in Hanghzhou. Ironically, the zebra crossing where the accident took place is titled the “Zebra crossing of Living Hearts” in memory of the May 7 car accident in Hangzhou.
