单选题 Passage 2 Every year, the American Lung Association (ALA) releases its annual report card on smog, and every year it gives an "F" to over half the nation's counties and cities. When ALA's "State of the Air 2002" recently came out, dozens of credulous local journalists once again took the bait, ominously reporting that their corner of the nation received a failing grade. The national coverage was no better, repeating as fact ALA's statement that it is "gravely concerned" about air quality, and neglecting to solicit the views of even one scientist with a differing view. Too bad, because this report card says a lot less about actual air quality than it does about the tactics and motives of the ALA. The very fact that 60 percent of counties were given an 'F' seems to be alarmist. This is particularly true given that smog levels have been trending downward for several decades. According to the Environmental Protection Agency (EPA) statistics, ozone, the primary constituent of smog, has declined by approximately 30 percent since the 1970s. And recent gains indicate that the progress will likely continue, even without the wave of new regulations ALA is now demanding. ALA is correct that some areas still occasionally exceed the federal standard for ozone, but such spikes are far less frequent than in the past. Even Los Angeles, the undisputed smog capital of America, has cleaned up its act considerably. Los Angeles, which exceeded federal smog standards for 154 days in 1989, has had 75 percent fewer such spikes in recent years. But an ALA-assigned "F" misleadingly implies that air quality has not improved at all. Most of the nation is currently in attainment with the current smog standard, and much of the rest is getting close. Nonetheless, ALA chose to assign an "F" to an entire county based on just a few readings above a strict new EPA standard enacted in 1997 but not yet in force. In effect, ALA demanded a standard even more stringent than the federal government's, which allows some leeway for a few anomalously high readings in otherwise clean areas. ALA further exaggerated the public-health hazard by grossly overstating the risks of these relatively minor and sporadic increases above the standard.

单选题{{B}}Passage Three{{/B}} Every Thursday evening, I counsel a group of teenagers with serious substance abuse problems. None of the youngsters elected to see me. Typically, they were caught using drugs, or worse, by their parents or a police officer and were then referred to my clinic. To be sure, all the usual intoxicants--alcohol, marijuana and cocaine-are involved. But a new type of addiction has crept into the mix, controlled prescription drugs, including painkillers. This is hardly unique to my clinic. Several studies report that since 1992, the number of 12-to 17-year-olds abusing controlled prescription drugs has tripled. One of my patients, Mary, illustrates this trend all too well. Mary at 16 is a "garbage head", meaning that she will ingest anything she thinks will give her a high. Last December, she was taken to the hospital for an overdose of alcohol, and ketamine, a chemical cousin of angel dust that doctors sometimes use to anesthetize patients and that, more commonly, veterinarians use to sedate large animals. So where does this physically energetic teenager obtain her pills? Weeks earlier, she had an operation, a minor though uncomfortable procedure by any standards. The surgeon wrote a prescription for 80 tablets. Mary spent the next week in the addiction of the drug until her mother confiscated the last 20 tablets. At medical conferences, I hear colleagues fault parents who abuse and obtain these controlled substances but leave them easily accessible in their unlocked medicine chests where teenagers can help themselves. Other experts fault the Internet, where al-most anyone can obtain controlled prescription drugs from offshore pharmacies with a few clicks on a home computer. None of these targets come close to the real root of the problem. Many doctors are too quick to write prescriptions for these powerful drugs. The National Center for Addiction and Substance Abuse recently reported that 43.3 percent of all American doctors did not even ask patients about prescription drug abuse when taking histories; 33 percent did not regularly call or obtain records from a patient's previous doctor or from other physicians before writing such prescriptions; 47.1 percent said their patients pressured them into prescribing these drugs; and only 39.1 percent had had any training in recognizing prescription drug abuse and addiction. No one in pain--physical or psychic--should suffer. But the fact remains that we doctors still do the bulk of prescribing of the substances. The search for root causes of the epidemic with controlled substance abuse has to include doctors as active participants. A big part of the solution depends on reserving prescriptions for those who need, rather than de-sire, them.
