问题    Flight attendants are stepping up pressure to close what some call a back door to airport terrorism: ground-crew security. Nearly eight months after the terrorist hijackings, thousands of airport mechanics, caterers and ramp workers still have access to airplanes and runways without passing through metal detectors or undergoing regular searches.
   Transportation Department spokesman Lenny Alcivar says ground-crew employees "must go through a thorough background and criminal records check as well as prescreening procedures." At most airports, however, those workers are not subject to regular searches or asked to pass through metal detectors as pilots and flight attendants are.
   The access continues, despite provisions in the new Aviation and Transportation Security Act that require tighter measures. The Transportation Security Act, passed by Congress after the hijackings, requires workers with access to a "secured area of an airport" to be screened in a manner "that will assure at least the same level of protection as will result from screening of passengers and their baggage." Those screening measures should be taken "as soon as practicable." "Whether background checks and random searches fulfill the provisions of the law is an open question, " says David Schaffer, counsel to the House subcommittee on aviation. He says the law requires "some sort of screening, " but it does not require ground-crew employees "to go through metal detectors."
   Deciding which steps to take will not be easy. Workers often leave and reenter secured areas. Making them pass through metal detectors or regularly searching them would be burdensome. Moreover, because the layout of each airport is different, developing uniform standards could prove difficult. Even so, reports from flight attendants around the nation indicate that few searches of ground crew are being conducted, and only a swipe card is needed to access secured areas at many airports. Results of tests from November through early February by the Transportation Department’s inspector general underscore the concerns. Memos obtained show that undercover agents secretly boarded aircraft or gained access to the runway in nearly half their tries. We are only creating the illusion of security where the traveling public can see. Meanwhile, the part that they cannot see, nothing is being done.
The word "underscore" in Paragraph 4 probably means______.
选项 A、ignore
B、emphasize
C、respect
D、estimate
答案B
解析 本题为词义分析题。underscore意为“强调”。这句话的意思是“交通部检查员在11月至2月初进行的测试结果突出了这一问题”。A项ignore意为“忽视，无视”；B项emphasize意为“强调”；C项respect意为“尊重”；D项estimate意为“估计”。因此B项正确。
