　　你知道什么是龍卷風(fēng)，什么是颶風(fēng)嗎？你知道它們的威力有多大嗎？ The violence of nature What is a tornado? A tornado is a rotating(旋轉(zhuǎn)的)column of air from a thunderstorm to the ground.The most violent have winds of more than 400 kilometres per hour.Almost all of them occur in the US，in the area from Texas in the southeast to South Dakota in the north. Tornadoes can pick up cars，trains and even houses and put them down in the next street—or even in the next town.They can take the fur off the back of a cat and the feathers off a chicken.They can destroy houses，but leave the furniture inside exactly where it was.
