Do you know what makes lightning(闪电)?Why does lightning strike(击打)?
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).Lightning can strike inside the cloud, between two clouds or between a cloud and Earth. It’s the last kind of strike that is the most dangerous for humans.
Lightning can be very dangerous. Every year, lightning kills people because it can start big fires or because it reaches a temperature of 28, 000 ℃. About 1, 000 people are hit by lightning every year in the United States, and about 100 of them die as a result.
Lightning makes people shocked, and it happens all over the world! Scientists think that there are more than three million lightning strikes every day in the world—that’s thirty strikes every second(秒). An American man Roy Sullivan, who worked in a park, survived from the most lightning strikes. Between 1942 and 1983, he was hit seven times! And he keeps the highest world record.
Lightning is sure not something to play 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. Also, do not lie down on the ground, or the electricity may go through you and cause a heart problem.

3 . Earthquakes usually come without warning. What should you do if this happens to you? An earthquake is dangerous, but there are still things you can do to protect yourself.
Stay calm as the earth begins to shake. Your chances of survival in an earthquake go up if you can keep calm. Staying calm is not easy, but it can save your life.
If you are inside when the earthquake starts, get under a table or a bed. You need to have something strong around you to protect you from falling objects. Do not stand near walls and windows and stay out of the kitchen. The kitchen is dangerous because of many glass objects.
If you are outside, get to an open area as fast as you can. Stay away from buildings and trees. If you are in a car, pull over to a place where there are no trees or tall buildings and stay in the car. If you are close to the sea, try to get as far away from the water as possible. Earthquakes can cause huge waves(浪) that can really harm the people nearby.
When the earthquake is over, there is still plenty of danger. For example, gas fire often comes with an earthquake. If you see a fire, quickly move outdoors to an open area.
Always remember to hope for the best but prepare for the worst.

5 . Oct 29, 2012 was a dark day for the American people. A huge hurricane (飓风) named Sandy hit the US, along with thunderstorms, heavy snow and flooding. It caused great damage in many places. Cities like New York were left with flooded streets and no electricity.
A hurricane is a kind of tropical cyclone (热带气旋) that is found in the northeastern Pacific Ocean, South Pacific, or North Atlantic Ocean. When it appears in the northwestern Pacific, it is called a typhoon. Southern China has the longest record of experiencing typhoons in the area.
So hurricanes and typhoons are the same thing; the only difference is where they happen. They form on the sea and are caused by temperature differences.
There is another kind of cyclone called a tornado. A tornado forms from the twisting (扭曲) of rising air. It's a violently rotating (旋转的) column of air that connects with clouds above it and the land below.
Tornados form on the land and often begin with thunderstorms. The US has the most tornados of any country. This is because of some of the special features of the North American continent. The continent spreads from the tropical north to the arctic (北极的). There are no large mountains from east to west, so it is easy for warm and cold air to meet. When this happens, thunderstorms soon follow.
As for Hurricane Sandy, scientists believe that it began due to unusually warm water. Then it joined with a large Arctic weather system, which increased its size and changed it into a winter storm with far more power.

C.It came with thunderstorms and rain. | D.It caused little damage to New York. |

7 . Last Friday a storm swept through two villages in the New Territories, destroying (摧毁) fourteen homes. Seven others were so badly damaged (破坏) that their owners had to leave them, and fifteen others had broken windows or broken roofs(屋顶). One person was killed, several were badly hurt and taken to hospital, and a number of other people received smaller hurt. Altogether (总共) over two hundred people were homeless(无家可归) after the storm.
A farmer, Mr. Tan, said that the storm began early in the morning and lasted for over an hour.
“I was eating with my wife and children,” he said, “when we heard a loud noise. A few minutes later our house fell down on top of us. We tried our best to climb out but then I found that one of my children was missing. I went back inside and found him safe but very scared.”
Mrs. Wu Meifeng said that her husband had just left for work when she felt that her house was moving. She ran outside at once with her children.
“There was no time to take anything,” she said. “A few minutes later, the roof came down.”
Soldiers(战士)helped to take people out of the flooded (水淹的) area and the welfare department (福利机构) brought them food, clothes and something to stay at.

9 . Tornadoes(龙卷风) are one of the worst weather events on earth. Each year, tornadoes kill many people. The storms often carry homes, cars and trees from one place to another. And they can alsodestroyanything when they pass by.
A tornado comes from a thunderstorm(雷雨) in the sky down to the ground. It is big at the top and small at the bottom.
A tornado appears when winds in different directions meet in the cloud and begin to turn in circles. People can see tornadoes almost everywhere in the world. But most happen from late winter to middle summer. There is a second high season in November. During spring, warm air moves north and mixes with the cold air left from winter. In November, the opposite happens. Cold air moves south and mixes with the warm air left from summer.
Tornadoes always come suddenly. Weather scientists have done something to predict(预测) tornadoes. But the storms often move too fast for people to protect themselves. Last year, tornadoes killed more than one hundred people in United States.
Scientists say the best place to be in is a small room, without windows, in the middle the lowest part of a building when tornadoes come.

10 . Hello, my name is Sabrina. I was around lightning while taking a hike in the Grand Canyon, but I was safe because I knew the following tips.
Outdoors If there is a thunderstorm (雷雨), try to find a low place to stay in until the storm is over. You can also go into a nearby building or a car. Make sure that the windows of it are closed. Do not stand under a tree or use the umbrella with metal things. If the lightning is around you, do a “lightning couch”! Squat down (蹲下) with your heels (脚后跟) together and put your hands over your ears. Remember not to lie down. |
Indoors During a thunderstorm, stay away from anything that is made of metal such as TVs, refrigerators because lightning can come into the house through wires (电线). When there is a thunderstorm outside, don’t stand near the windows. And don’t take a bath when there is a thunderstorm. Never use the phone during a thunderstorm, because lightning can hit the phone line and travel through the line and hit you. |
