第二节：书面表达(满分25分)

Recently I have learned from the Internet that traffic accidents happened frequently, which mainly resulted from drunk driving.

　　 Many drivers think they have the luck to avoid accidents. As a matter of fact, no one can afford to risk their lives driving after drinking. Drunk driving will not only threaten the lives of the drivers as well as other people, but also make their family suffer from anxiety caused by it. In addition, drunk driving is against the law and more and more people are punished for it.

　　 In a word, for the sake of the safety of all people and the happiness of your family, please don’t drive after drinking.
