[简答题]

Although hard statistics are difficult to come by, there is substantial anecdotal evidence that use of performance-enhancing drugs, or doping, is rampant in professional sports. Of perhaps greater significance to society are the estimated 1.5 million amateur athletes who use steroids, either to improve their appearance or to emulate the performance of their favorite professional athletes. This chemical epidemic is a pernicious threat to both the nation’s health and our collective sense of "fair play".
Nonprescription anabolic steroids(合成代谢类固醇) have been illegal in the United States since 1991, and most professional sports leagues have banned them since 1980s. These bans are party a matter of fairness—a talented athlete trained to the peak of her ability simply cannot compete with an equivalent athlete using steroids—but also based on issues of health.

[不定项选择题]共用题干 Chest Compressions:Most Important of CPR

Cardiopulmonary resuscitation or CPR,can save the life of someone whose heart has stopped.The

lifesaving measures,the brain starts to die within four to six minutes.CPR combines breathing into the
victim's mouth and repeated presses on the chest._________(46)
However,a new Japanese study questions the usefulness of mouth-to-mouth breathing. The study was
published in the British medical magazine,The Lancet. Doctors in Tokyo led the research.It examined more
than four thousand people who had suffered cardiac arrest.In all the cases,witnesses saw the event happen.
More than one thousand of the victims received some kind of medical assistance from witnesses.Seven
hundred and twelve received CPR. Four hundred and thirty-nine received chest presses only._______(47)

treated with only chest presses suffered less brain damage.Twenty-two percent survived with good brain
ability._________(48)
The American Heart Association changed its guidelines for CPR chest presses in 2005._________(49)
Gordon Ewy is a heart doctor at the University of Arizona College of Medicine in Tucson.He wrote a report
that appeared with the study.Doctor Ewy thinks the CPR guidelines should be changed again.He said the
heart association should remove rescue breaths from the guidelines.He argues that more witnesses to cardiac
arrests would provide treatment if rescue breaths are not a part of CPR.He says this would save lives,
