Lightning is one of the most powerful weather forces to hit Earth. These huge electricity that strike (撞击;击打) during storms can cause destruction and death. Lightning can heat the air around it to temperatures five times hotter than the surface of the sun.

Lightning is very common. It is estimated (估计) that every second, about 100 lightning strikes hit the surface of the Earth.

Lightning can be deadly. It is difficult to keep exact records on how many people die from lightning each year throughout the world. Some experts estimate that about 2, 000 people die each year from lightning. Others say the number could be as high as 24, 000.

So how to stay safe during a lightning storm is important. Experts at the weather gov (政府) website, give tips on staying safe if lightning comes your way.

Outdoor lightning storm

If you are outside, you should take cover, which means finding a safe shelter for protection. During a lightning storm, no place outside is safe. If you hear thunder, lightning is close enough to strike you. Most lightning victims (受害者) are in open areas or near a tree.

Nowhere to hide

If you are outside during a lightning storm and there is no safe shelter, these actions may reduce your risk:

●Immediately leave high land areas, such as hills or mountains.

●Never lie flat on the ground.

●Never shelter under a tree sitting in the open.

●Immediately get out of any bodies of water and stay away from those areas.

●Stay away from objects that can conduct electricity, such as wire fences, tall buildings, power lines or windmills.

Indoor lightning storm

Stay off wired phones, computers and other equipment that can put you in direct contact with electricity.

●Avoid any areas with running water.

●Remain indoors but stay away from windows and doors.

●Do not lie on concrete (混凝土) floors or touch concrete walls.

The past years have shown we need to prepare for the worst earthquakes. So an earthquake emergency kit (急救包) should be something we need to have. 【小题1】 Well, that may not be a problem because you can buy your own one online.

According to experts, around 275 earthquakes are felt every day around the world. 【小题2】 There is a 30% higher chance that you will survive (幸存) an earthquake if you have the kit.

Some people think they can go to a shelter after an earthquake. 【小题3】 There may be too many people in the shelter. You may not find food or water, either.   

【小题4】 But whether you are near the fault line (断层线) or far from it, owning one for your household is still a must. Studies show that some states that are near the fault line have earthquake magnitudes (震级) of above 4.5. 【小题5】

So if you don’t have an earthquake emergency kit at home, make one yourself or buy one online.

A.This only means that you never know how earthquakes hit until they hit you.
B.Some people say that they don’t have time and money to prepare emergency kits for earthquakes.
C.Some people don’t think they need an earthquake emergency kit because they don’t live near the fault line.
D.But shelters can’t solve all problems.
E.Half of these are large enough to require that families should own earthquake emergency kits.
F.However, instead of depending on your shelter, an earthquake emergency kit is your best choice when an earthquake happens.
