   Gao Xiaosong, who is a famous musician, movie director and the writer of the famous song My Deskmate,

has been sent to jail (监狱) and will stay there for six months for drunk driving.

   "I've nothing to say for myself and I'm willing to be punished (惩罚)," he said when he was standing in the

court. "What I want to say is that I feel sorry for what I've done. I thought alcohol (酒精) could bring me

freedom but never realized drunk driving could take away others' freedom. And now I've lost my own freedom

because of drinking. I'll obey the new road safety rules and I want to be a life-long volunteer in persuading

(劝说) others not to drive after drinking."

   Anyone who drives after drinking doesn't think much of human life. If Gao had cared, he would have left his

car parked outside the restaurant and took a taxi home, and he would have thought about a road killer he would

become. It's fair to say that his behavior can not be excused in modern society. Gao may not have killed anyone, but by choosing to drive a car while under the influence of alcohol, he and the large number of others who do

the same have made the dangerous decision that may possibly hurt other people.
