The last two tornado seasons have been the deadliest in a
decade, with 206 deaths. Everyone from the insurance industry to
Al Gore worry that global warming may be causing more tornado【S1】______
activity. But there’s no baseline for comparison. That’s why we have【S2】______
no accurate record of tornadoes before the 1950s, back when it was
possible for these brief, freakish funnels of air to blow over the
unpopulated areas without a notice.【S3】______
Tornado warnings have improved over the years; forecasters
can now issue warnings about 18 minutes after touchdown for 75【S4】______
percent of twisters. As longer-term forecasts, the science isn’t there【S5】______
yet, despite that you hear on the nightly news. " Television【S6】______
forecasters cater with the public’s curiosity about extreme weather,"【S7】______
says Michael H. Glantz, a professor at the University of Colorado at
Boulder. Their goal, of course, is to be first with a forecast of
trouble ahead.
The number of deaths per tornado is greater in the South than
in Tornado Alley(the Great Plains and part of the Midwest)—a
disparity that can’t be explained for storm frequency or severity.【S8】______
Experts say things like terrain, population density, and the number
of mobile homes play a role. And the biggest factor might be timing:【S9】______
"In the Plains," explains Schaefer, "we have a many more clearly【S10】______
defined period of tornado activity, generally from March to late
June. In the Southeast, tornadoes can happen all year long, so
there may be less vigilance. " Research also shows that the South
may have a climatological propensity(倾向)for nighttime storms,
which catch people unawares—asleep in bed. Last year’s two killer
tornado outbreaks in North Carolina landed between 11: 30 p. m.
and 3: 30 a. m. [br] 【S4】
选项
答案
after—before
解析
语义错误。此句说“龙卷风预警已经得到改进,预报可以在龙卷风触地18分钟前发出”,因此用before,如果用after,不符合逻辑。
