The summer is coming, and the storms are often. Though they happen often, some people don’t take them seriously. 1) In fact, it’s very ______ for people and it even can ______ people die at once.

So how do we keep safe during a lightning storm?

If you are indoors, stay away from windows and doors during a lightning storm. Don’t take a shower or do some dishes, because lightning can travel through water. Turn off the TV and computer. I learnt the hard way, and my computer was broken. Never use the phone. Lightning could travel through the phone line and hit you.

If you are outdoors during a lightning storm, never take shelter under a tree, because the lightning could hit the tree and travel through the trees to hit you. Stay away from anything that is metal. Try to get in your car and close all the windows or go into a nearby building right away.2) If there is no building around, try to find a low place to stay in. Squat(蹲) down near the ground and put your hands over your ears. Never use a cell phone.
