More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment. Maybe that's why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

    Get on a bicycle and ride around your neighbourhood. You may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your car.

    You can bike to work and benefit (受益) from the enjoyable exercise without polluting  the environment. You don't even have to ride all the way. Folding (折叠) bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take a common bike with you when you fly. But be sure to look for information by getting on airline websites. Not all airlines are bicycle-friendly to travellers.

Health Benefits of Bicycling:

    It helps to prevent heart diseases.

    Bicycling helps to control your weight.

    A 15-minute bike ride to and from work three times a week burns off five kilos of fat in a year.

    Bicycling can improve your mood (心情).

    Exercise like bicycling has been shown to make people feel better, more relaxed and self-confident.

    Bicycling is healthier than driving.

    The Things Successful People Do Differently

    Why have you been so successful in reaching some of your goals, but not others? If you aren't sure, you are far from alone in your confusion. It turns out that even brilliant, highly accomplished people are pretty lousy when it comes to understanding why they succeed or fail. The intuitive(直觉的) answer--that you are born with certain talents and lacking in others--is really just one small piece of the puzzle. In fact, decades of research on achievement suggests that successful people reach their goals not simply because of who they are, but more often because of what they do.

    1）Get specific.

    When you set yourself a goal, try to be as specific as possible. “Lose 5 pounds” is a better goal than “lose some weight,” because it gives you a clear idea of what success looks like. Knowing exactly what you want to achieve keeps you motivated until you get there. Also, think about the specific actions that need to be taken to reach your goal. Just promising you'll “eat less” or “sleep more” is too vague--be clear and precise. “I'll be in bed by 10pm on weeknights” leaves no room for doubt about what you need to do, and whether or not you've actually done it.

    2）Seize the moment to act on your goals.

    To seize the moment, decide in advance when and where you will take each action you want to take. Again, be as specific as possible (e.g., “If it's Monday, Wednesday, or Friday, I'll work out for 30 minutes before work.”) Studies show that this kind of planning will help your brain to detect and seize the opportunity when it arises, increasing your chances of success by roughly 300%.

    3）Know exactly how far you have left to go.

     Achieving any goal also requires honest and regular monitoring of your progress--if not by others, then by you yourself. If you don't know how well you are doing, you can't adjust your behavior or your strategies accordingly. Check your progress frequently--weekly, or even daily, depending on the goal.

    Back in 1969, it was the Apollo 11 crew who flew to the moon in a spaceship. When U.S. astronauts Neil Armstrong and Edwin “Buzz” Aldrin stepped foot on the moon, they were the first. Meanwhile, their fellow astronaut Michael Coilins circled the moon in their spaceship, named Columbia.

    When Armstrong and Aldrin were done with their walk，they returned to the command module, and back to Earth. That part of the spaceship is on view at the Smithsonian's Air and Space Museum in Washington, D.C. But, if you cannot get to Washington，soon you will be able to see Columbia on your computer or your smartphone.

    Digital scientists are scanning the inside of the spaceship. They are creating an online model, in three dimensions, or“3 D”. By looking at these photographs, you will be able to see outer space，the way the astronauts did. It will be like sitting in their seats.

    Want your very own Columbia spaceship? You will be able to print a 3D copy of Columbia. Experts say anyone can make a life-sized model. But they expect most people to make smaller models of the 320×400 cm(11'X 13')command module.

    Scientists are using special 3D technology to scan the inside. They use cameras on long arms to take the photographs. The thousands of photographs taken will be combined with 50 laser scans.

    What would it be like to sit inside Columbia and take a look around? All the images will be loaded into software that allows you to look around the module on a computer screen. The user will be able to see the Columbia both inside and out. The Smithsonian says that the 3D technology gives the user ways to see things they cannot see at the museum. And it will give information that even the museum curators(馆长)have not seen before.

    “With the Command Module, no one has been inside since it came into the collection,” says Adam Metallo. Smithsonian 3D imaging specialist. “Now the information we capture can give anyone in the world a view of what it looks like inside this incredible piece of history.”

    She was returning from teaching out in a small community. It was a black, moonless night, and a heavy snow was falling.

    She thought back to the time when she had first started teaching out in small communities. During those days she had always picked up hitchhikers (搭便车者), until the day her sister told her that one of her friends had been shot in the head by a hitchhiker, all because she had stopped out of kindness to help him during a storm.

    Her family didn't stop worrying about her safety over the hitchhikers until the family heard the promise: “No more hitchhikers!” The snow that night was making her think back to this.

    Then she saw a man waving. She slowed down for him, but as he ran toward the car in the dark, she shook with fear. Yet she thought that if he was truly in need, she couldn't leave him here in this storm.

    The stranger explained that his car was dead, and she told him to get in. They drove for an hour into the next city and she took him to a convenience store. She waited until he had made a call. When he reported back to her that a family member would soon come to pick him up, she wished him well and then left.

    Tears fell on her cheeks as she drove away. It felt as though she had been holding her breath for an hour.

    “I hope they'll understand why I had to break my promise,” she thought.

    It takes a special person to travel with kids—a parent. Children have their own needs. Their idea of a vacation is more “adventurous” than a parent's. They need constant inspiration and they can get as tired as they are tiring.

    Make sure you have plenty of room while traveling

    If you are driving, get a mini-van. Sure, you might be more of a “car” type, and you might have resisted buying a mini—van so far. But pick up a rental van for the vacation just to give the kids a little more room for fighting.

    Accommodations along the way can be tricky. Usually it involves a crowded motel for just long enough to sleep, then back in the crowded car. This is not anybody's idea of a home away from home. An accommodation alternative is to camp, but not everyone enjoys a good early morning wake-up wrestle with a bear as much as I do, so a motel might be required.

    Make sure you have plenty of room when you “get there”

    Assuming you are actually heading for a destination, make sure to have lots of room when you get there. This part is easy. But it requires thinking outside the box. Forget hotels, motels, and inns. Look for private rental homes.

    Probably the biggest destination for families is Walt Disney World in Florida. Good news—Orlando, Kissimmee and the surrounding area is full of private vacation homes for rent. In Florida they call them vacation villas, and they offer all the space of home.

    Be prepared for “children being children” events

    Sometimes, stress hits you from behind when the unexpected happens. Like a cut or a scrape…or a child getting sick. Sharon Baillie told me that is why she tells all her villa rental guests where the first-aid case can be found, and exactly where to go for medical attention. This is particularly helpful for her many guests from abroad, who are unfamiliar with the US healthcare system.

    Booking tickets to theme parks and making reservations for just about everything in advance makes the trip less stressful. Try having your children baby-sat. Hire a local baby-sitter once or twice. Vacation Home owners can set this up for you, and some hotels might be willing to, too.

Cruz Genet,11, and Anthony Skopick, 10, couldn't agree. Were the birds out on the ice ducks or geese? So on a 1 January evening last year, the two friends ventured onto the 2 pond near their homes, to get a better look. First they tossed a rock onto the ice to3 it. Then they stepped on it. 4 the ice would hold their weight, Anthony took a few steps, then…FOOMP. He crashed through the 5 frozen surface." There was no sound, no crack," he recalled,"I just fell through instantly". Cruz 6 to help his panicked friend. FOOMP— the pond 7 him too.

 The boys were up to their necks in icy water and quickly losing feeling in their limbs. Any chance of their 8 themselves was slipping away. Cruz was sure he was going to die. Anthony's older sister was nearby and started screaming for help.

 John Lavin, a9 driving nearby on his way home, heard her. He quickly 10 . Seeing the boys, he grabbed a nearby buoy (救生圈), 11 off his shoes, and ran into the cold water, chopping(劈) his way through the ice with his free 12 .

 Lavin made his way to Cruz and Anthony and pulled them back to land. When in hospital, doctors discovered that their five- minute 13 in the water had lowered their body 14 nearly ten degrees.

 Fortunately, the boys have fully recovered, though they are still a little awestruck by their 15 neighbor." Just to think," says Cruz," If he weren't there, we could have died."
