Wildfires are uncontrolled (不可控制的) fires. They usually happen in areas where few people live. They are most common in wooded areas in the US, Canada and Australia. They are also known as forest fires or grass fires, or as bushfires in Australia.

Lightning (闪电) strikes and volcanic eruptions (火山爆发) can cause wildfires. However, 90 percent of wildfires are caused by humans, according to the US National Park Service. Dry and hot weather, as well as wind, creates perfect wildfire conditions. They help wildfires spread quickly and last for weeks.

Wildfires can burn at over 900℃ and reach heights of more than 50 meters. Wildfires can move at speeds of up to 23 kilometers an hour, burning everything – trees, brush, homes, even people – in their path.

The fires are also dangerous to animals. In Australia, koalas can’t get enough water from tree leaves because of wildfires. They have to leave their trees and find water somewhere else.

But sometimes, fires can be good for some plants. People can find more of them in the wild after a fire.

Every year in the U. S, there are about 500 tornadoes, a natural disaster (灾害；灾难), from Texas through Oklahoma, Kansas, Nebraska, lowa and into South Dakota.     1    .

The “tornado season” is usually in spring, but the people in Tormado Alley are always ready for them and they always listen to the news. When the warnings come,     2    . They find somewhere safe to stay. At home, the best place is the basement—a room that is used to store things under the level of the ground. If there is no basement, a room without windows like the bathroom is also a safe place.

“    3     so that we can get ready and won’t feel afraid when there’s a tornado,” says Tiffany Taylor, a high school student from Texas. “There’s no basement at my school, so we usually go to the hallways on the lowest floors. Of course, we never sit near the windows.”

After the tornado, people first check to see if it is safe to go out and then they check the buildings and the area for damage (破坏).     4    !

In China, we are not so often troubled by tornadoes, but we do have disasters like earthquakes, or an unexpected fire. It is important to know how to keep us safe when a disaster happens. Remember: in order to stay safe in natural disasters,     5    . For example, we’d better keep disaster plans in mind and practice often.

Many animals do strange things before an earthquake. This news may be important. Earthquakes can kill people and knock down homes.     1    

Some animals make a lot of noise before an earthquake. Farmers have told about this.     2     Horses on farms run around in circles. Mice leave their holes and run away.     3    

In a town in Italy, cats raced down the street in a group. That happened only a few hours before an earthquake. In San Francisco, a man kept tiny pet frogs. One Sunday, the frogs jumped around more than ever.     4     That night, an earthquake struck the city.

People want to know when an earthquake is coming so they can get away safely.     5     Maybe the best idea is to watch the animals.

【推荐1】Although it’s said Van Gogh (梵高) (1853 — 1890) sold only one painting during his lifetime, different theories (理论) exist (存在).

It is true that The Red Vineyard is the only painting sold during Van Gogh’s lifetime, and that was officially (官方地) recorded and accepted by the art world. It’s recorded that Van Gogh started painting at 27, and died at 37. His famous paintings were produced after he went to France in 1888, only two years before he died. So it would be clear that he did not sell many.

However, others disagree. The leading Van Gogh scholar (学者), Mare, is one of them. Though the story that Van Gogh sold just one painting still goes around, he insists (坚持说) that Van Gogh sold at least two.

Also, according to the Van Gogh Museum website, Van Gogh actually sold a number of paintings for living during his lifetime. His first money came from his uncle, who was an art dealer (经销商). In order to help Van Gogh’s career (事业), he ordered 19 paintings. And Van Gogh himself would often trade his paintings for food or art supplies (美术用品) when he was younger.

Van Gogh died in July of 1890. His brother was a wise dealer and saved lots of paintings by Van Gogh. His greatest wish was to make the works more widely known and make much money. Sadly he himself died just six months later. He left a large collection of art to his wife, who “sold some of Van Gogh’s works, lent as many as she could to exhibitions, and published (出版) many of Van Gogh’s letters to his brother. Without her, Van Gogh would never have become as famous as he is today.” After her death, her son founded the Van Gogh Museum.

【推荐3】The opening ceremony of the 2022 Winter Olympics was held in Beijing on Friday night, February 4th. Social media users described it with these words: amazing, flashing and shining.

The main stage of the ceremony in the National Stadium, commonly known as the Bird’s Nest, is designed to be like a huge Chinese character “Zhong”, covering almost the whole stage. In fact, it is the world’s largest ground LED screen. The screen, with a size of 10,552 square meters, was actually made up of about 42,000 small LED units. The huge ground screen, together with a 10-meter-high vertical (竖的) screen, allowed the audience to have a wonderful experience.

To build such a big ground LED screen wasn’t an easy task. As the main stage, on which all performances and the Parade of Nations (入场式) took place, it had to be strong, water-proof (不透水) and able to support heavy weights. What was more challenging, as the stadium is open-air, the ground screen had to be able to support the winter freezing temperature, as well as weather like rain and snow. To solve all the challenges, technicians built a special protective covering for it.

With the help of AI, 5G, AR and naked-eye 3D technologies from the company CALA, which once offered them to the 2008 Beijing Summer Olympics opening ceremony, the ceremony presented many amazing moments. The most unforgettable moment is when the Olympic Rings were “carved (雕刻) out” of a 3D shaped like a block of ice on the screen. Another great point is that children sang and danced across the stage, when stars appeared on the screen under their feet.

Thanks to the screens, creative ideas and high technologies, the two-hour ceremony only needed around 3,000 excellent performers, compared with 15,000 during the 2008 Beijing Summer Olympics opening ceremony. It greatly meets the theme of energy saving.

Thomas Bach, the president of IOC believed that the 2022 Olympic Winter Games would be “in safe hands” when Beijing won the right to host the 2022 Olympic Winter Games in 2015. The amazing ceremony showed the world that China has kept its promise of hosting a fantastic event with strong determination (决心) and confidence.
