问题     Most of us know to stay low to the floor if we’re caught in a fire, or head to the basement if a storm’s coming, or board up the windows in a hurricane. But because relatively few of us live along fault lines, the massive earthquake that hit Haiti was a reminder that we’re far less experienced in what to do when the ground below us shakes. If we’re in a house or building, for example, our first impulse might be to run outside—but, counterintuitive(与直觉相反的)as it might sound, experts warn against that since people are too often killed by falling or fallen objects as they try to escape.
    Of course, just as the best way to survive car crashes is to make safer cars, the best way to reduce the risk of being killed in an earthquake is to enact stronger building codes. But given how many of us travel in quake-prone regions today—including, tragically, the four students and two professors from Lynn University in Florida who perished in the Haiti quake—even folks who don’t reside in California should know how to survive an earthquake. But there are two different, and at times competing, schools of thought on the matter—both of which are considered valid but perhaps not always in the same situations.
    The most conventional and widely accepted practice by the disaster-response community is the "drop, cover and hold on" approach, which urges people to take cover beneath something like a heavy table to avoid falling objects. The newer method—and less researched—is known as the "triangle of life." It rec-ommends lying down in a fetal position not under but next to furniture; as roofs and walls collapse on the top of those sofas and desks, buffer(缓冲)spaces are created that protect people from being crushed. Over the past decade, a consensus has been building that "drop, cover and hold on" is a more appropriate method for developed countries like the U.S., where improved construction has greatly reduced the likelihood of structures collapsing inwards. The triangle of life is thought to be more suitable in developing nations like Haiti, where inferior building codes make finding a "survivable void" inside collapsed buildings more important than shielding yourself from falling pieces. "You have to think about the hazard level of the area you’re in," says Gary Patterson, a geologist and director of education and outreach at the Center for Earthquake Research & Information at the University of Memphis in Tennessee. "If you’re going to play the odds, drop and cover may be the best way to go, but a lot of emergency responders might say triangle of life because they’re the ones who see the fatalities in buildings that do collapse."
As for which method to choose in an earthquake, Gary Patterson suggests basing the choice on_____.
选项 A、your whereabouts
B、the intensity of the earthquake
C、the "drop, cover and hold on" approach
D、the "triangle of life" approach
答案A
解析 该句表明Gary Patterson建议，地震时应选用哪种方法，应先考虑the hazard level of the area，即应先考虑身处的地方可能造成什么危险，再决定用“蹲下、掩护和抓牢”的办法还是“生命三角”的方法，由此可见，本题应选A。
