We often hear the phrase： “Youve a greater chance of being struck by lightning.” It is used to describe something that hasnt got much chance of happening. However， the common saying undermines （掩盖） the very real dangers of lightning. Last Friday， at least 5 people were killed by lightning in Nepal. Lightning strikes are the second most common cause of deaths during natural disasters in the US. The first is floods. Around 400 people nationwide are struck by lightning each year， and of those 73 people die. That means more people are killed by lightning than by tornadoes and hurricanes. Because lightning kills only one or two people at a time， its danger does not receive as much attention as other disasters.

So to raise awareness， the US has made June 22 to 28 National Lightning Safety Week. It aims to warn the public of the dangers of lightning and provide safety tips during thunderstorms. “If you hear thunder， you are in danger from lightning，” said Rocky Lopes， a disaster educator at the American Red Cross. “Thunder means that lightning is close enough to hit you at any minute， so you should move indoors immediately and stay there until after the storm has ended. The single most important thing to remember is to seek hiding place，” Lopes said.

Summer is the high time for lightning storms， so when lightning strikes across the sky， remember these safety tips：

Stop working， fishing， swimming or playing in open fields.

If you can count less than ten seconds between a thunder and a lightning flash， take cover inside the nearest building.

Do not stand under a tree.

Get off bicycles or motorcycles.

Crouch down （蹲下） if there is no hiding place.

Avoid open spaces， wire fences， metal objects and electrical objects such as hair driers.
