【推荐2】A fully electric seaplane has made its first flight over the mouth of the Fraser River near Vancouver, Canada. The flight represents a milestone in the long process of reducing the aviation industry’s emissions and costs by electrifying short-to-medium distance commercial flying.

Several hundred people crowded the river bank on Tuesday morning to witness what they hoped would be a historic moment. They were not disappointed. Among cheers, the battery-powered Harbour Air seaplane lifted off into the sky. The plane flew a short round-trip downriver before landing five minutes later.

“It was magical. It was much quieter than I had expected it to be,” said Nicki Malcom, one witness from Auburn, Washington. “It’s definitely the future,” said Chip Jamison, who came from Portland to see the electric plane he produced parts for. “You can see it with automobiles. Planes are next. It's right in front of us.”

The test pilot was the only person on board the six-passenger DHC-2 de Havilland Beaver. He was the CEO and founder of Habour Air, Greg McDougall. McDougall’s seaplane airline teamed up with a Redmond, Washington-based electric motor maker named Magnix to transform the classic de Havilland Beaver plane. Magnix CEO Roei Ganzarski sees the seaplane's first flight as a milestone, similar to the first jet takeoff.

“Today you witnessed the first shot of the electric aviation revolution,” Ganzarski told the two companies' staff, contractors, media and other celebrators. “Let’s start the revolution.” Ganzarski laid out a case for how battery-powered flight offers lower noise, zero pollution and could reduce fuel and maintenance costs. “Lower operating costs for airlines like Harbour Air will mean lower ticket prices for all of you,” he said. “Lower operating costs mean they can now fly to more destinations that we couldn’t fly to before.”

It will be some time before regular folks can book a ticket on a clean, electric seaplane.

【推荐2】For a scholar focusing on Australia’s public diplomacy (外交活动), working as a recreational manager in China may never be part of his career path. But Bradley does have lots to say now about his special experience at a resort in the picturesque tropical coastal city of Sanya in South China’s Hainan province.

The 33-year-old Australian is actually a student in international relations completing his PhD through Griffith University. He came to Beijing for a cooperative research at Peking University less than two years ago. Such an academic life was just added color with a chance offered by the cultural exchanges project, “I’m in China”.

“What I liked most about the experience was it was something completely different that you would never be able to do as a regular tourist,” Bradley said in an interview. Bradley was chosen to work as a recreational manager for a Chinese wedding.

The film crew took them to many “amazing sites” and the staff at the resort taught them a lot about how to “incorporate modern Chinese features while still keeping traditional customs”, Bradley said.

“I would have to say two things stick out as the most memorable: the helicopter ride and talking with the staff at the hotel about how to organize weddings here in China,” he said.

That was Bradley’s first time to be in a helicopter, and he was too absorbed with the “stunning” view of the beautiful coastline.

“I think it is so important to show other Australians the different landscapes China has to offer. I think so many Australians, when they think about China, imagine the historical sites of Beijing and the exciting things to see in Shanghai but have no idea about other beautiful places, like Sanya or the many other places people have been taken to in this TV series,” Bradley said.

“I’m in China” is a project sponsored by China Intercontinental Communication Centre and other institutions under the guidance of China’s State Council Information Office. It invites foreign natives worldwide to experience unique jobs and participate in activities that one can find nowhere else except in China. More than 10,000 photos and articles were submitted from around the globe by over 6,00 applicants.

【推荐3】China is known as a state of manners and ceremony. Many proverbs have been passed down from generation to generation such as “polite behavior costs nothing” or “showing respect each other” and so on. For instance, there is an interesting short story. Once upon a time, a man went on a long tour to visit his friend with a swan as a gift. But it escaped from the cage on the way. Though he tried hard, he got hold of nothing but a feather. Instead of returning home, he continued his journey with the swan feather. When his friend received this unexpected gift, he was deeply moved. And the saying “The gift is nothing much, but it’s the thought that counts.” was spread far and wide.

Chinese used to cup one hand in the other before the chest as a greeting. This tradition has a history of more than 2, 000 years and nowadays it is seldom used except in the Spring Festival. And shaking hands is more popular. Bowing, as to show respect to the higher level, is often used by the lower like subordinates(下级), students, and attendants. But at present Chinese youngsters prefer to simply nod as a greeting.

When you start a talk with a stranger, the topics such as weather, food, or hobbies may be good choices to break the ice. For a man, a chat about sports, stock market or his job can usually go on smoothly. Similar to Western customs, you should be careful to ask a woman private questions. However, relaxing talks about her job or family life will never put you into danger. Though Chinese are said to be implicit(含蓄的), they are actually humorous enough to be pleased about the jokes of Americans.

【推荐1】Parents will do anything for their children. Whether it would be the food, clothes, or the place they live in, parents will always make sure their children have the best of everything. One of the biggest concerns that parents currently have is educating their children. They are faced with lots of difficulties when it comes to education for their young ones. Choices include private school, charter school, public school or home schooling.

Fortunately for parents, there are a variety of different strategies that they can take in order to increase their child’s overall intelligence. According to Ross A. Thompson, PhD, professor of psychology at the University of California at Davis, a child’s brain will actually reach 90% of its full size by the time they start kindergarten.

Researchers at Northwestern University in Chicago concluded that playing a musical instrument directly affected the brain stem, the lower section of the brain. Moreover, children that learn an instrument at an early age tend to continue it when they are older. And numerous studies show that a well balanced meal is essential for a child’s mental as well as physical health. Some other researchers recommended that a second language should be taught when children are in preschool. They state that three to four years of age is the perfect time and that any age under four would work perfectly fine for a child’s brain development.

The average child will learn how to read between kindergarten and second grade. Many parents can give their children a jump start by teaching them to read before they start school. Children could have an adequate background of the alphabet and sounds of words before attending school. This can be done by simply reading to them whenever you want. The more comfortable they get, the easier the process will be.

【推荐3】Can you still remember the things happening when you were a child? Grown­ups are often amazed by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins “Twinkle, twinkle, little star” or remember the story of Cinderella or Goldilocks and the Three Bears.

One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning trials (尝试) increase the length of time we will remember it.

In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as “Twinkle, twinkle, little star” and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

The multiplication tables (乘法口诀表) are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

The law of overlearning explains why cramming (突击学习) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one’s future development.
