    Terrafugia Inc .said Monday that its new flying car has completed its first flight,bringing the company closer to its goal of selling the flying car within the next year.The vehicle-named the Transition – has two seats，four wheels and wings that fold up so it can be driven like a car.The Transition,which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the flies using a 23-gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.

    Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don't  expect it to show up in too many driveways. It's expected to cost $279,000.And it won't  help if you're stuck in traffic. The car needs a runway.

    Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The govemment has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition  is now going through crash tests to make sure it meets federal safety standards.

    Mann said Terrafugia was helped by the Federal Aviation Administration's decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition,a requirement pilots would find relatively easy to meet.

    Modern fathers spend an average of six and a half hours a week playing with their children. A study said this equals 338 hours a year, or just over 14 days, three whole days more fun time than their own fathers spent with them.

    The report said modern parents are ''adventurous”, as many encourage their children to play outside. A third of parents also prefer family trips which encourage children to learn new skills, and most say that having fun together improves family ties. The study said the lack of time that today's parents shared with their own dads encouraged them to be more active with their children.

    Dr. Amanda Gummer, psychologist and founder of Fundamentally Children, a company which provides advice on child development, said being adventurous helps children. She said, “Being adventurous from an early age helps children develop important skills that will last throughout childhood and set them up for a healthy and successful adulthood.”

    Outdoor activities are a popular choice for dads and their children, with 40 percent choosing nature trails and 26 percent looking for wildlife, while 13 percent say their top outdoor activity is climbing trees. The simple things are the most popular, with 46 percent going to the park and 41 percent choosing to kick a ball around their children.

    Dr Gummer said, “Children are able to challenge themselves by being more adventurous, and they can be safe in the knowledge that their dad will be there to help if things start getting out of control. Parents can help encourage their children's adventurous, outdoor spirit with wildlife treasure hunts and adventure playgrounds. They can even do more exciting things, like going on camping trips.

    Last week, my granddaughter started kindergarten, and I wished her every success. But part of me didn't. I actually wanted her to fail in some ways because I believe that failure can be good for our learning process. Success is proving that you can do something that you already know you can do, or doing something correctly the first time, which can often be a problematic victory. First-time success is usually a luck. First-time failure, however, is supposed to be the natural order of things. Failure is how we learn.

    In Africa they describe a good cook as “she who has broken many pots”. If you've spent enough time in the kitchen to have broken a lot of pots, probably you know a fair amount about cooking. I once had dinner with a group of cooks, and they spent time comparing knife wounds and bum scars. They knew how much their failures gave them.

    I earn my living by writing a daily newspaper column. Each week I know that one column I write is going to be the worst column. I try my best every day. I have learned to love that column. A successful column usually means that I am discussing my familiar topic, writing in a style I am used to or saying the same things as anyone else but in a better way.

    My younger daughter is a trapeze artist（荡秋千演员）. She spent three years practicing a show, and she did it successfully for years. There was no reason for her to change it but she did anyway. She said she was no longer learning anything new and she was bored. She risked failure and great public embarrassment in order to feed her soul.

    My granddaughter is a perfectionist. She will feel her failures, and I will want to comfort her. But I will also, I hope, remind her of what she learned, and how she can do better next time.

    Hobbies in general are becoming something of the past. Our lives are already filled with classes, homework, working, relationships and sleeping. When we do have a spare moment, it is all too easy to spend it on the endless entertainment and media that are right at our fingertips.

    I do not doubt that there are some people who could become a great writer or musician. I only fear that so many people are busy pursuing their education and their careers, but they never even see the potential (潜能) they have. The next great photographer or singer could be going to college right now. But they might not even know they have a gift for photographing or singing if they've never picked up a camera or a guitar.

    Of course, the final goal of pursuing a new hobby shouldn't be to become rich and famous. For most people, a hobby is just something they enjoy doing for the purpose of the thing itself. Such hobbies are still very useful. Studies have shown that people who have a hobby are less likely to have stress and more likely to have more meaningful lives.

    Most importantly, a hobby is just something you do to make you happy. I hate to break it to you, but we all have a long lifetime of work and stress ahead of us. It will make things much easier if we can practice the piano or make some collections after work.

    Sure, it's not easy to start a new hobby while going to school, but it will likely never get easier than it is right now. So think about the thing that you have always wanted to try but were too embarrassed or busy or whatever. You never know, you might become the world's next great people. If not, you'll at least be a little more well-rounded, more interesting and less stressed.

    Fish have different personalities which change as they experience life's highs and lows, according to British biologists.

    Researchers identified different "personalities" in their fish by observing the boldness(大胆) or shyness of individuals, according to The Nature. Like people, some fish are very confident in the face of novelty or conflict, while others are silent and fearful.

    The scientists selected particularly bold and shy rainbow trout(虹鳟鱼), and tested whether they changed their outlook depending on what life threw at them. They arranged some fish to fight and others to watch to see how both the participants and observers responded to victories and defeats. Winning or losing a fight, or even watching fellow fish overcome the difficulties influenced the future behavior of the creatures studied in the lab.

    The researchers made fish compete with much larger or smaller opponents(对手), to ensure that they would win or lose their fights. These bold fish that won their fights tended to be even bolder when later presented with a novel food item; losing their fight caused them to be much more cautious.

    Fish also learn by watching others. Bold fish watching a shy fish exploring a mystery object were much more nervous when later given a novel item for themselves.

    Predictably, shy fish that won a fight also gained more confidence, but surprisingly, shy fish that lost their fights also grew bolder when exploring strange new food, Sneddon said, adding that this could be due to what she calls a "desperado effect"(亡命徒效应).

    The new research suggests that animals can gradually adapt(使适应) their personalities. The results agree with the effects that life experience can have on humans.
