如果你见过我的朋友大卫,那你从他说话时的那副淘气相、平易的微笑、半吞半吐的谈笑中,绝对想象不到他一度曾染上可卡因毒瘾,曾经每天静脉注射多达20次,由于吸毒过量,曾经每天都要心脏病发作,由于经常咬舌头,使其只剩下原来的3/4大小。我认识大卫是在1991年,他从澳大利亚来美国学医,我是他四年级时的教授,而他教我打网球。我们交往一年半之后,有一个周末,他的女朋友离他而去,他便买了可卡因。注射后,又旋即出去买了更多的回来。他当时做实习医生,每天要工作好长时间。 If you’ve seen my friend David, the naughty, easy smiles and half-swallowed joke you talked to him never imagined that he had been infected with cocaine once, Intravenous injection up to 20 times, due to drug overdose, had a heart attack every day, due to often tongue, leaving only the original 3/4 size. I know David in 1991, he came to the United States to study medicine from Australia, I was his fourth grade professor, and he taught me to play tennis. One and a half years after our meeting, one weekend, his girlfriend left him and he bought cocaine. After injection, and immediately went out and bought more back. He was an intern at the time, working long hours every day.
