READINGPassage 1Read the passage carefully and choose the best parts to fill in the blanks What exactly is a tornado? The general picture is familiar enough. The phenomenon usually occurs on ahot, sticky day with south wind and an ominous sky. From the base of a thunderhead, a funnel-shapedcloud extends a violently twisting spout toward the Earth. As it sucks in matter in its path, the twister mayturn black, brown or even white. The moving cloud shows an almost continuous display of sheetlightning . It lurches along in a meandering path, usually northeast ward, at 25 to 40 miles per hour.Sometimes it picks up its finger from the earth for a short distance and then plants it down again. Thefunnel is very slender; its wake of violence averages about 400 yards wide. As the tornado approaches, itis heralded by a roar as a hundreds of jet planes or thousands of railroad cars. Its path is a path of totaldestruction. Buildings explode as they are sucked in by the tornado’s low-pressure vortex ( where thepressure drop is as much as 10 percent ) and by its powerful whirling winds ( estimated at up to 500 milesper hour ). The tornado’s lifetime is as brief as it is violent. Within a few tens of miles ( average about 16miles), it spends its force and suddenly disappears.
