        Do you know what makes lightning (闪电)?

        Lightning strikes happen when ice and water in clouds rub (摩擦) together, and cause atmospheric (大气层的) changes. When this happens, it creates a static charge (静电). Lightning can strike inside the cloud, between two clouds or between a cloud and the earth.

        Lightning can be very dangerous. Every year, lightning kills people because it can start big fires or because it reaches a temperature of 28,000℃. About 1,000 people are hit by lightning every year in the United States, and about 100 of them die as a result.

        Scientists think that there are more than three million lightning strikes every day in the world. An American man, Roy Sullivan, who worked in a park, survived from the most lightning strikes. And he keeps the highest world record.

        Lightning is sure not something to play with. When lightning strikes, it's best to stay inside a large building. Also, do not lie down on the ground, or the electricity may go through you and cause a heart problem.
