a 第47 至50 題為題組 After Thomas Hicks, an American marathon runner, collapsed right after he won the race in the 1904 Summer Olympics, people found that he didn't rumple because of exhaustion but because of the mixture of egg whites, brandy, and Strychnine, which is now used as an ingredient of Pesticide . This strange incident isállegedly the regson why the 1908 London Olympics forbade athletes to use drugs during the games. T. Doping, however, is nothing new in Olympics .

(More than a hundred Russian athletes are reported to be barred from the 2016 Rio Games as Russians allegedly bribed anti-doping officials to swap their athletes’ urine samples. Though it's difficult to give exact numbers of athletes who use drugs to enhance their performance, according to a study in 2015) about one third of outstanding athletes are involved in doping to some degree. Performance-boosting drugs are not exclusive to Olympians. Any 30-something young man who is into working out in the gym could be taking inabolic steroids from time to time. Though each year, athletes and their trainers find new plans to consume or administer drugs, there is not much change in the types of drugs.
