Tornadoes are nature's most violent storms, which can cause deaths and destroy a neighborhood in seconds. A tornado appears as a funnel-shaped (漏斗状) cloud from a thunderstorm to the ground with whirling (飞快移动) winds that can reach 300 miles per hour. Damage paths can be over one mile wide and 50 miles long. Every state is at some risk from this disaster.

    Some tornadoes can be seen clearly, while rain or nearby low-hanging clouds obscure others. At many times, tornadoes develop so rapidly that little, if any, advance warning is possible.

    Before a tornado hits, the air may become very still. A cloud of debris (散片) can mark the location of a tornado even if a funnel can not be seen. Tornadoes generally occur near the edge of a thunderstorm, when the strong wind may die down. It is not uncommon to see clear, sunlit skies behind a tornado.

The following are facts about tornadoes:

    The average forward speed of a tornado is 30 MPH, but may also vary from still to 70 MPH. Debris is picked up or a cloud forms in the funnel.

    The average tornado moves from southwest to northeast, but tornadoes have been known to move in any direction. Tornadoes are most often reported east of the Rocky Mountains during spring and summer months.

    Tornadoes can happen together with tropical storms and hurricanes as they move onto land. Waterspouts are tornadoes that form over water.

    The tornado season in the southern states of America is March through May; in the northern states, it is late spring through early summer. Tornadoes are most likely to occur between 3 p.m. and 9 p.m., but can occur at any time.

    Did you know that badminton is also a fast-paced competitive sport? Badminton has been a Summer Olympic sport since 1992. Para-badminton will be included in the 2020 Summer Olympic Games in Tokyo. Here's what you need to know if your child is interested in badminton.

    What's the meaning of "dark horse"? It's someone who wins when no one expects it.Han Xiaopeng took China's first gold on snow. He became an Olympic "dark horse" by winning the gold medal in men's freestyle aerial skiing(自由式滑雪空中技巧) at Turin in Italy. He made two almost perfect jumps for the highest score. Han had never won a world gold medal before, let alone(更不用说) in the Olympics!

    "I never thought this would happen," said the 23-year-old. "I feel like I'm in a dream." It's China's second gold medal at the Turin Olympics. But more important, Han's gold was the country's first ever in a snow sport. In 2002, China's Yang Yang won the gold for speed skating at the winter Olympics in Salt Lake City, US.

    That Han's win was unexpected doesn't mean that he didn't work hard.

    Han grew up in Jiangsu Province. Before he started his training on snow, he used to be an acrobat(杂技演员) at a circus. In 1995, a coach found his talent(才能). The coach, Yang Er'qi, said Han had the agility(灵活性) and courage to be a ski jumper. When Yang first took the 12-year-old to northern China, the boy couldn't swim, skate or ski. But he wasn't afraid of the high platform(跳台) and kept on training.

    Han almost left the sport after hurting his knee months before the Salt Lake Games. In that Olympics he only got 24th. "I was hopeless at that time, but my family and the coach stood firmly(坚强地) behind me, helping me through," he recalled.

    Han Xiaopeng worked so hard that he won the gold medal in the Olympics at last. Because of his success, more and more people in China are becoming interested in skiing. We are proud of him and we hope he will have another big success in the next winter Olympics.

    A strange object was found in a small city called Carlos Spegazzini, just a short drive from the capital city of Buenos Aires.

    When farmer Jose first found an odd scene in his farmland, he began to dig at the object. However, he quickly found himself running to tell his wife. Jose needed more support if he was going to investigate this strange thing.

    Even the dog was hesitant to investigate. Unfamiliar with the object, man's best friend was not about to jump at it with little concern. Therefore, they chose to call in somebody who has a better idea of what to do.

    When the police first showed up, they were just as stumped as Jose. They knew this object was something out of the ordinary. It might even be something extraordinary, so more questions appeared.

    It quickly became apparent, it was time to call in the big guys. That's right; when you find something that appears to be out-of-this-world, it's time to call in those who study the mysteries of the old world.

    Authorities called in archaeologists who jumped at the chance to study the object. They quickly determined one thing was for certain: the ancient big one that left this behind was absolutely massive! The group was unable to move the shell, as it weighed nearly two tons!

    Clearly, this massive beast was not the only of its kind existing in the modem-day world. Similar fossils had been found in the surrounding areas and had even made their way to museums. But what was the ancient beast?

    NAIROBI­Tin Tin, a Chinese restaurant located in central Nairobi, has been serving local Kenyans for nearly four decades with its delicious dishes and unique cultural background.

   "This is a restaurant definitely worth a try," said Steven, a local resident in his 30s. "It has provided Chinese food since my grandfather's time."

    According to Henry Tin, the restaurant owner, Tin Tin was established in 1978 at the heart of the Nairobi Central Business District, upholding Chinese cuisines while adapting to Kenyan preferences.

    For years, it has become a defining part of the city's landmark­Kenya International Conference Center­attracting lots of office workers nearby and even presidential customers.

   "The former president of Kenya, Moi, was a very good customer for us. He came almost always in cash. Then former president Mwai Kibaki and now president Uhuru. They all like to enjoy our food," Tin said.

    Danis, an office worker of an insurance company near the KICC says he is a frequenter of the restaurant.

   "It is the only Chinese restaurant in the highly competitive downtown area. Besides, its food has been adapted to our taste," Danis said, "My favorite dishes are fried shrimp and fried pork, which you can also find in a Kenyan restaurant."

   "High­quality food consistently served over the decades has helped maintain loyal customers," Enoch Kivunaga said, at Tin Tin.

   "My experience depends on the customers. If I cook good food, they always come back, whether they are presidents or ministers," he said.

    Tin said he speaks Swahili well and perfectly pronounces local names, which shows the Chinese culture and its Kenyan counterpart are quickly combining. "I am a Kenyan Chinese. I love both great countries."
