Look, this is the first plane in the world to be created using the new technology of “3D printing”. The airplane was built using only a computer-but it can fly at a speed of 100mph and has a two-meter wingspan.
It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a “snap fit”（搭扣） technique so the aircraft could be put together without tools in minutes.
No fasteners(扣件) at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as “laser sintering(激光烧结) “and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost.
Professor Jim Scanlon, who led the team, said, “The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing.” He added, “This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense.”
The new printed plane is known as the Southampton University Laser Sintered Aircraft-or SULSA for short-and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s.

Does a 600-year-old Chinese map prove that Christopher Columbus was not the first international explorer to navigate(航行) the New World?
In his book “Who Discovered America?”, published on Tuesday, author Gavin Menzies says the settling of North America by nonnative peoples is more complex than previously thought.
“The traditional story of Columbus discovering the New World is absolute fantasy. It’s fairy tales,” Menzies, 76, said in an interview with the Daily Mail.
However, not everyone is sold on the theory. It has been described as “Unreal” by critics, who say Menzies’ claims are impractical and not based in historical fact.
Menzies has primarily focused his studies on when and how North America was first explored. He also has enthusiastic supporters—his previous books have been best-sellers, and supporters of his theories have donated millions to his efforts, allowing him to hire a number of experts to join in his investigatons.
Menzies says that the Chinese map, found in a bookstore, was drew by Chinese navigator Zheng He and shows a detailed map of America dating back to 1418. That would place Zheng He’s efforts some 70 years ahead of Columbus. In fact, Menzies says Columbus used a copy of Zheng He’s map to plot his own voyage.
The map itself has been authenticated(鉴定), but there is currently no way of proving the map was based on images drafted in the 1400s. However, Menzies says that certain observations on the map, including descriptions of communities and other cultural landmarks in Peru, coincide with known data from that period. In addition, Menzies makes an even broader claim in his book, saying that Chinese sailors were the first to cross the Pacific Ocean 40,000 years ago. Menzies says there is DNA evidence to support his claim.
So how does Menzies believe the Chinese pulled off such a giant historical accomplishment thousands of years before anyone else?
“If you just go out in a plastic bathtub, the currents will just carry you there,” Menzies told the Mail. “They just came with the current; it’s as simple as that.”
Critics of Menzies point out that he holds no degrees or professional training as a historian. But the Daily Mail says he “can no longer be called an amateur” after his most recent efforts.

A Tale of Two Cities was written by the famous English writer Charles Dickens. The tale is mainly about the French Revolution in 1789, where the poor rose up against the king and the nobles. Dickens showed deep sympathy for the poor and deep hatred for the cruelty of the upper class, though he wrote quite a lot about the love triangle between Lucie, Charles and Sydney.
In this novel, Dickens wrote some lively characters like Sydney and those crazy revolutionaries. In this tale, we can’t see any absolute roles. Charles, though he’s a brave and good man, obviously he hasn’t as much ability as Sydney. Sydney, a typical tragic(悲剧的) man, a man like him, usually has great ability. But he has some weak points on characters and the worst is that he always loves a woman he shouldn’t love and 99.99% die for her at last in an extremely heroic or tragic way. The revolutionaries are not as full of justice as usual. They get mad when they can get revenge(报复) for their unfair treatment. The fire of hatred burns everything. When they’re at the bottom of the society, they’re calling for justice, for fair treatment, for freedom, but when they’re in charge of the society, their world is up-side-down. They hate everything that is connected to the very people against them, even including Charles’ wife, Dr. Manette’s daughter. So these men have no difference from those former governors at heart.
Though Dickens told us how the authority is recycling over and over again in some way, the novel is about something good. Love from Sydney to Lucie is one of the only few bright points in the novel and it’s really great. A man can sacrifice his life to save his lover’s husband. He doesn’t have any personal purpose and just for his lover’s happiness. So Dickens may imply us, only love can solve the problems between people, between the poor and the rich, love is everything.

My grandmother was from a town in Michigan. Summer after summer, I enjoyed staying with my grandparents as a young child. I was from the city and loved the small town they lived in. People knew everyone, their kids, their pets, their ancestors. The bond with them continued to grow as I grew and they got older. Grandma was always using her hands for something exciting. She would make little sandwiches and we’d have tea parties. She’d make beautiful quilts for each one. I remember the small thimble(顶针) she would use while doing her needle work.
A few years ago, when Grandma left this earth, I bid farewell to a loving grandmother. How quickly our lives can change. We had just had tea together a couple of months earlier, on her 91st birthday.
On one particular birthday, when I was feeling a little low, something happened to make me feel like she was sharing that special day with me. I was arranging some colorful pillows that she had made, and suddenly I felt something inside one pillow. It was small and hard. I moved the object to a seam(接缝) that I carefully opened, and to my delight out came a tiny silver thimble! How happy I was to find something that had been a part of her. I carefully laid the thimble alongside the others I’ve collected over the years, where I could continue to see the gift God chose to reveal(启示)to me. What a precious memory of a very special lady who somehow, I knew, was laughing in delight at sewing her thimble inside my pillow.
I made some tea, using my best china, as Grandma always did, and enjoyed my tea and Grandma’s thimble. What a wonderful birthday that was!

The Soul Knights have a noble , which is to advocate civilized travel by taking photos of graffiti(涂鸦) by tourists.
“When we heard that a Chinese tourist wrote his name on an Egyptian temple, it made think a lot. We wanted to use photos to everyone how important it is to protect historic relics,” says Zhang Zhihao, 22, the team’s captain.
