Lightning(闪电)is shocking, and it happens all ...

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.

1.Lightning strikes ________.

A. happen three billion times each day

B. will start when there are big fires

C. can reach very high temperatures

D. kill all those who work in a park

2.What does “surviving” in paragraph 2 mean in Chinese?

A.目睹　　　　 B.幸存　　　 C.制造　　　　 D. 遇难

3.We can infer(推断)from paragraph 3 that ________.

A. lightning strikes are caused whenever ice and water meet

B. lightning between two clouds is the most dangerous for humans

C. lightning strikes create static charge

D. about one tenth of the people struck by lightning die every year in America

4.Which expression means “to toy with” in the last paragraph?

A. to play with　 　 　　 B. to take seriously

C. to show off　　 　　　 D. to take it easy

5.Where’s the best place to be when lightning strikes?

A. On top of a hill.　　 B. In a swimming pool.
