Lightning(闪电)is shocking, and it happens all over the world! Scientists think that there are more than three million lightning strikes(袭击)every day in the world-that’s thirty strikes every second.

Lightning can also be very dangerous. Every year, lightning kills people because it can start big fires or because it reaches temperatures up to 28,000 degrees centigrade. American Roy Sullivan, who worked in a park, holds the record for surviving the most lightning strikes. Between 1942 and 1983, he was hit seven times!

So, why does lightning strike? 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(静电电荷). Lightning can strike inside the cloud, between two clouds and between a cloud and Earth. It’s the last type of strike that is the most dangerous for humans. About 1,000 people get struck by lightning every year in the United States, and about 100 of them die as a result.

Lightning is certainly not something to toy with. When lightning strikes, it’s best to stay inside a large building. To stay safe, do not stand under trees, on hills or near water. Trees attract lightning. Also, do not lie down on the ground, otherwise the electricity may go through you and cause a heart disease.

When I was ten, my mother worked all day so I had to take care of my younger brother. At that time my little brother was about four years old and he missed mum all the time.

One day, after I had given him his dinner, he started crying for mum. He was so young and really needed mum. So I dressed him, put on his shoes, carried him on my back and walked out. Soon he fell asleep. About half an hour late, I found that he had lost a shoe while sleeping. I took him off my back and put him down. I knew we needed to find that shoe, for our mother couldn`t afford new shoes. We had to go back to find it, so I told my brother to Wait right here. A man heard it and stopped me just before I walked off. He asked me, ”You are leaving your brother here to find the shoe? What would you do if he is not here when you return?” I did not know how to answer that question. He continued,: It is OK if you can`t find the shoe, but it is not OK to lose your brother.” Then he sent us to mum`s workplace by taxi.

I have depended on the kindness of many strangers in my whole life. I feel regretful that I cannot find them and say thank you. I don’t even remember what the man`s face looked like, but he taught me a lesson—people are more important than things.
