Electrical devices (仪器) could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.

    The device connects to a person's knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.

    There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers (起搏器). It could even be used to assist in the movement of robotic arms and legs.

    The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version should be ready in one year.

    The developers hope the device will one day help developing countries. Nearly twenty-five percent of people around the world live without electric power.

    A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person's back that also produces power from walking. The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms.

    For 80 years, Macy's Thanksgiving Day Parade has kicked off the holiday season with glorious bands, balloons and floats (花车)，and for one day, it has transformed New York City into a living comic book.

    The Macy's Thanksgiving Day Parade is an annual parade presented by Macy's Department Store. It was first held in 1924. It was organized by Macy's employees, most of whom were first­ generation immigrants(移民)，who wanted to celebrate holidays like they did in Europe. The employees dressed in costumes(盛装)and marched on the streets with floats, bands and live animals borrowed from a zoo.

    With an audience of over a quarter of a million people, the parade was such a success that Macy's declared it would become an annual event.

    In 1927 Felix, the Cat became the first parade balloon to float over the city. Large animal­ shaped balloons replaced the live animals from then on. These giant signature(特有的)balloons are by far the biggest attraction of the parade. Each year sees parade balloons adding new characters from comic strip characters to timeless toys.

    One tradition long gone is the releasing of the balloons after the parade. They would float for days and the lucky finder or finders could claim a cash reward if he or she returned the balloon or its remains to Macy's.

    The parade has gone on every year except during World War Ⅱ when, aside from not having much to cheer about, the helium(氦气)air and rubber used for the balloons were needed for the war effort.

    When the parade returned in 1945，it was televised in New York for the first time and also traveled its current route for the first time.

    Nowadays, more than 10,000 people participate in the parade and the National Broadcasting Company(NBC) will nationwide broadcast it live from 9 a.m. to noon. The NBC has even earned several Emmy Awards for this program.

    As always, the parade will end with a visit from Santa Claus. The joyful old man will get settled in Macy's Department Store after the parade to start a­month­long search for who's been naughty and who's been nice.

    Sure, it's good to get along with your teacher because it makes the time you spend in the classroom more pleasant.

    And yes, it's good to get along with your teacher because, in general, it's smart to learn how to understand the different types of people you'll meet throughout your life

    "But really, there's one super-important reason why you should get along with your teacher. When you do, learning bursts right open," says Evelyn Vuko, a longtime teacher who writes an education column (专栏) called "Teacher Says" for the Washington Post newspaper.

    In fact, kids who get along with their teachers not only learn more, but they're more comfortable asking questions and getting extra help. This makes it easier to understand new material and do your best on tests. When you have this kind of relationship with a teacher, he or she can be someone to turn to with problems, such as problems with learning or school life like bullying.

    As a kid in a primary or middle school, you're at a wonderful stage in your life. You're like a sponge(海绵), able to absorb lots of new and exciting information. On top of that, you're able to think about all this information in new ways. Your teacher knows that, and, in most cases, is very excited to be the person who's giving you all that material and helping you make it. Remember, teachers are people, too, and they feel great if you're open to what they're teaching you. That's why they wanted to be teachers in the first place—to teach!

    Some kids may be able to learn in any situation, whether they like the teacher or not. But most kids are sensitive to the way they get along with the teacher, and if things aren't going well, they won't learn as well and won't enjoy being in class.

    Police Officer Tidwell left the station just after 8 a.m. on Sunday June 4. He had spent a boring night on duty and was looking forward to his day of rest. By habit he took a short-cut down the path behind Dugby Hall road and after a minute or two he saw a man climbing down a drainpipe (雨水管)from an open bedroom window of Number 29. In silence, Tidwell crept into the garden. The man reached the ground and was dusting himself down when he felt his arm caught.

    "It's 8:15 on a Sunday morning," said the officer, "and this sort of thing seems an unlikely adventure at such a time. Would you mind explaining?"

The man was obviously scared but tried to keep calm. He said, "I know what you are thinking, officer, but it isn't true. This is a funny mistake."

    "It's part of my job to take an interest in unusual events. I think you've just left this house in a manner other than the customary one. That may be quite innocent, but I'd like to make sure." Tidwell took out his notebook and a pen. "Name, address and occupation and then, please, tell me your story..."

    "Charlie Crane, lorry driver, from Nottingham, 51 Breton Street. My story..."

    "Yes. What were you doing like a fly on that wall, Mr. Crane?"

    "Well, I had a breakdown yesterday and had to stay the night here. Bed and breakfast. The land-lady's name is Mrs. Fern. She gave me breakfast at seven, and I was out of he: mthe right way and down at the lorry by half past seven. Only when I felt around for a cigarette did I realize I'd left $80 in my envelope under the pillow here at number 29. I always put it under my pillow at night. It's a habit I've got into. I even do it at home...

    "I see. Why didn't you miss it when you went to pay Mrs.... What's her name?"

    "I'd paid her last night. You've got to pay when you take the room, see? So I came rushing back, but it's Sunday, and she'd gone back to bed, and could I wake her? I rang the bell and banged on the front door for ten minutes before I came round here to the back and spotted my bedroom window still open. Up I went, then, up this pipe. It's a trick I learned in the army. She didn't make the bed、and money was still there. You know the rest, I hope you believe it because... "

    "Mr. Crane, whatever are you doing here? I thought you'd gone an hour ago." It was Mrs.  Fem, speaking from the kitchen at the corner of the house.

    Only about 30 percent of people in the US know how to perform CPR (心肺复苏术). Recently, a 9-year-old boy showed a Georgia woman how to perform CPR on her newborn baby.

    Susanna Rohm said she had experienced a parent's worst nightmare (噩梦) — her 2-month-old son, Isiah, was not breathing. "I noticed he looked pale. I looked at his arms and his legs and they were limp (无力的)," Rohm told a local newspaper. "Then I noticed that he looked like he wasn't alive." Indismay, she dropped and broke her cellphone. Rohm had to run into the street, screaming for help.

    "I had him in my arms and screamed over and over. Then I ran outside. I saw two boys playing across the street, and I yelled, 'Go and ask your parents to call 911,'" Rohm said. But the two boys were able to do more than that. Nine-year-old Ethan Wilson took action, showing Rohm how to perform CPR on little Isiah while ten-year-old Rocky Hurt helped as well.

    Rocky said he had learned the CPR technique from a poster in a health class at their school, Sedalia Park Elementary. "I was thinking we'd better give her a helping hand instead of getting scared," Ethan said. "I told her to push on the baby's chest five to ten times a minute with only two fingers, tilt back the baby's head, plug the baby's nose and breathe into the baby's mouth," Ethan said in an interview.

    At last, Isiah began crying and was breathing again. He spent two nights in a local hospital. "If the little boy hadn't shown me what to do right there, my baby would probably not be alive right now," Rohm said.
