Henry Ford was born on a farm on July 30th, 1863. The farm was near the city of Detroit.

    Henry was always interested in machines. He enjoyed fixing clocks.And he helped repair farm equipment. When Henry was sixteen years old, he left the family farm and went to Detroit to learn more about machines. Henry used what he learned from work to develop engines. In 1903, he was ready to start building cars for the public. On July 15th, 1903, a man named Doctor Pfenning bought the first car from the Ford Motor Company.

    The sale to Doctor Pfenning was the beginning of a huge number of requests for Ford cars.By the end of March, 1904, almost 600 Ford cars had been sold. At the start of 1905, the Ford Motor Company was producing 25 cars each day.

    Henry Ford was sure the future of the automobile industry was in a low-priced car for the general public. He said then, and many times after,“I want to make a car that anybody can buy.”

    In 1907, Henry Ford said: "I will build a motor car for the great mass of people. 1t will be large enough for the family, but small enough for one person to operate and care for. It will be built of the best materials. It will be built by the best men to be employed. And it will be built with the simplest plans that modern engineering can produce. It will be so low in price that no man making good money will be unable to own one.”

    Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved.

    The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university's Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants' brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.

    Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.

    Contrary to popular belief, people who sleep six to seven hours a night live longer, and those who sleep eight hours or more die younger, according to the latest study ever conducted on the subject. The study, which has tracked the sleeping habits of 1.1 million Americans for six years, weakens the advice of many sleep doctors who have long recommended that people get eight or nine hours of sleep every night.

    “There's an old idea that people should sleep eight hours a night, which has no more scientific basis than the gold at the end of the rainbow,” said Daniel Kripke, professor of psychiatry（精神病学）at the University of California at San Diego who led the study published in a recent copy of JAMA Psychiatry.

    The study was not designed to answer why sleeping longer may be harmful or whether people could extend their lifespan by sleeping less.

    But Kripke said it was possible that people who slept longer tended to suffer from short-term absence of sleeping, a condition where weak breathing puts stress on the heart and brain. He also stressed that the need for sleep was similar to that for food, where getting less than people want may be better for them.

    The study quickly caused warnings and criticism（批评）, with some sleep experts saying that the main problem of America's sleep habits was deprivation（剥夺）, not sleeping too much.

    “None of this says sleep kills people,” said Daniel Buysse, a psychiatrist at the university of Pittsburgh Medical Center.

    “You should sleep as much as you need to feel awake, alert and attentive the next day,” Buysse added. “I'm much more concerned about people short-changing themselves on sleep than people sleeping too long.”

    “Sleeplessness produces a variety of health consequences that were not measured in the study,” critics said.

    The National Day holiday is a great opportunity to do something a little different. Many people use the National Day for a getaway, a short trip to leave the stress of their everyday lives behind and explore, learn, or relax.

    Hotel Romance

    Many hotels and resorts feature something special to start the getaway, such as champagne, flowers, or a fruit basket in the room on arrival. Getaway packages usually include a room with something special, a heart shaped bed, for example. Additional benefits could be room service meals or other private dining, plus tickets or discounts for local attractions.

    Visit a Spa

    Spa getaways can take place at a location that focuses only on spa services or at a hotel that offers a spa as one of its features. Some spas emphasize treatments fit for their geographic area or a local attraction. A spa in a grape growing region might provide grape juice masks, or a hotel near a hot spring could offer mineral baths. Most spas offer a range of massage, health and beauty treatments, so a spa getaway can be relaxing with other benefits.

    Learn a Skill

    The National Day holiday may not be enough time to become an expert at something new, but it provides a way for people to begin their explorations. Some organizations offer intensive courses that last five or six days. People with special interests can get away from their routines while learning such things as how to make beer, speak a new language, or take better photos.

    Help Others

    Some organizations cooperate with businesses to have accommodations and activities for short-term volunteers. Most volunteer vacations involve ecology friendly or charity activities. A volunteer getaway is a way to relieve stress and help others at the same time.

    Stay in a National Park

    For those who want to relax in a rural environment, a national park fits the bill. Most national parks provide camping areas for tents and trailers. Several have cabins within the parks available to rent. A getaway to a national park provides privacy, stress relief, and the time to get to know some important natural resources.
