Do you love holidays but hate the increase weight that follows? You are not alone.

    Holidays are happy days with pleasure and delicious foods. Many people, however, are worried about the weight that comes along with these delicious foods.

    With proper planning, though, it is possible to control your weight. The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy. The following suggestions may be of some help to you.

    Do not miss meals. Before you leave home for a feast(宴会),have a small, low-fat snack(小吃). This may help to keep you from getting too excited before delicious foods. Begin with clear soup and fruit or vegetables. A large glass of water before you eat may help you feel full. Use a small plate; a large plate will encourage you to have more than enough.

    Better not have high-fat foods. Dishes that look oily or creamy have much fat in them.

    Choose lean meat(瘦肉 ).Fill your plate with salad and green vegetables.

    If you have a sweet tooth, try mints (薄荷) and fruits. They don't have fat content as cream and chocolate. Don't let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess(过多的) calories.

    The past two decades have seen astronomers' catalogue of planets expand over two hundred times, as new techniques and better telescopes have found more than 2,000 of them orbiting stars other than the sun. But in the solar system itself, the list of planets has actually shrunk, Pluto（冥王星）having been downgraded from that status in 2006. The number of the sun's planetary companions has thus fallen from nine to eight.

    Now, a pair of astronomers from the California Institute of Technology think they have evidence that will restore the sun's record to its previous value. Their analysis of objects orbiting in the Kuiper Belt（柯伊伯带）, a ring of frozen asteroids（小行星）that circle beyond the orbit of Neptune (and of which Pluto is now regarded as the largest member), suggests to them that something about ten times as massive as Earth has changed those orbits. If you knew where to look, this planet-sized object would be visible through a suitable telescope. And Konstanin Batygin and Michael Brown believe they do know.

As they write in the Astronomical journal, they have analyzed the orbits of Kuiper Belt objects and found six that behave in a peculiar way. As the diagram shows, the points of closest approach of these objects to the sun, known as their perihelia（近日点）, almost coincide. Moreover, these perihelia all lie near the ecliptic（黄道）—the plane of Earth's orbit and also, approximately, that of the other planets—while the objects' orbits are all angled at 30° below the ecliptic. The chance of all this being a coincidence, the two researchers estimate, is about seven in 100,000. If it is not a coincidence, it suggests the six objects have been guided into their orbits by the gravitational intervention of something much larger.

    A computer analysis Dr Batygin and Dr Brown performed suggests this something is a planet weighing 5-15 times as much as Earth, whose perihelion is on the opposite side of the sun from the cluster, and which thus orbits mainly on the other side of the solar system from the objects its orbit has affected. This planet's perihelion would be 200 times farther from the sun than Earth's, and the far end of its orbit might be as much as six times that distance away. This gives a search zone, and Dr Batygin and Dr Brown are using Subaru, a Japanese telescope, to perform that search.

    Given other demands on Subaru's time, it might take five years for this search to find (or not find) the hypothetical planet. But looking at some existing data from. The Widefield Infrared Survey Explore, a satellite, might also show it, if it is there to be seen.

    Ironically, it was Dr Brown as much as anyone who was responsible for Pluto's downgrading, for he discovered Eris, an object almost as big as Pluto, in 2005.

    That discovery did much to damage Pluto's planetary proof. By his own admission, he was skeptical that the anomalies he and Dr Batygin have investigated actually would point to the existence of a replacement ninth planet. He is a skeptic no longer. Whether he is actually right may soon become apparent.

    You may hear about some people who have walked on the moon. Of the outstanding astronauts listed below, who do you think was the most influential in human's history?

Pete Conrad (Apollo 12)

    Because of his dyslexia（阅读障碍）, Pete always failed in his study and had to leave school. Then his father sent him to Darrow School, where he performed so well that he won a Naval Reserve Officers Training Corps (NROTC) scholarship. He took the NASA's test, but his dyslexia ruined the opportunity.

    It was because of Alan Shepard's persuasion that Pete decided to apply again for NASA. He was chosen as the commander of Apollo 12. He landed on the moon on Nov 19, 1969 and spent 31 hours there.

Neil Armstrong (Apollo 11)

    Armstrong's biggest moment came in 1969, when he was chosen for NASA's first manned lunar mission (登月任务), along with Edwin Aldrin and Michael Collins. On July 21, 1969, he set foot on the surface of the moon. which made him the first human to do so. He stayed on the moon for 21 hours. After returning, Armstrong became an international star and was honored worldwide.

John Young (Apollo 16)

    Young was made the commander of Apollo 16, which landed on the moon on April 16, 1972. He spent two days and 23 hours on the moon. Young retired from NASA after serving for around 42 years, which made him the man ever to work for NASA for the longest time.

Edgar Mitchell(Apollo 14)

    Edgar was selected by NASA in 1966, and was later made the lunar pilot of Apollo 14. He followed his commander Alan Shepard onto the moon, staying there for 1 day and 9 hours. Edgar has expressed his firm belief that UFOS belong to other planets. He also firmly believes that American government is in possession of some “recovered alien bodies.”

    After finishing a meal at an American Chinese restaurant you probably expect to receive a handful of fortune cookies after you pay the bill. Fortune cookies are in Chinese restaurants throughout the United States. It's rather satisfying to crack open a cookie at the end of your meal and read your “lucky fortune” on the slip of paper inside.

    The exact origin of the fortune cookie is unknown. It is thought that the tasty snack was the first introduced into San Francisco in 1914, after an immigrant began distributing the cookie with “thank you” notes in them. These “thank you” notes were intended as symbols of appreciation for friends who stood with him through the economic hardship and discrimination of his early life in America.

    There is an alternate origin story. Los Angeles is regarded as the site of the fortune cookie's invention. In this version of the story, David Jung, a Chinese immigrant residing in L. A., is thought to have created the cookie in order to uplift the spirits of the poor and homeless. In 1918, Jung handed out the cookies for free to the poor outside his shop and each cookie contained a strip of paper with an inspirational sentence printed on it.

    Fortune cookies first began to gain popularity in mainstream American culture during WWII. Chinese restaurants would serve them in place of desserts, as desserts were not popular in traditional Chinese cuisine. Today fortune cookies are not tied to Chinese-American culture. In fact, the largest fortune cookie manufacturer is located in the United States and it produces 4.5 million fortune cookies a day —— an evidence to the modern-day popularity of the snack. However, an attempt to introduce the fortune cookie to China in 1992 was a failure, and the cookie was cited for being “too American.”

    So the next time you break open a fortune cookie and read a fortune about the many successes you should expect in your future, remember that the conclusion to your Chinese restaurant meal may not be as Chinese as you think.

    Leadership today is not about forcing others to do things. If this is even possible, it is short-term. If you order someone to do something against their will, they may do it because they feel they must, but the anger they feel will do more harm in the long-term. They will also experience fear.

    Fear causes the thinking brain to shut down, making the person unable to function at his or her best. If they connect you with this emotion of fear, they will become less functional around you, and you will have succeeded in not only shooting yourself in the foot, but possibly making a very good employee or partner unable to perform effectively. Fear has no place in leadership.

    The way we affect people in a lasting way is by our own character, and our understanding and use of emotion. We can order someone to do something, which may be part of the work day, or we can employ them at the emotional level, so they become fully devoted to the projects and provide some of their own motivation（积极性）.

    Today's work place is all about relationships. Anyone works harder in a positive environment in which they're recognized and valued as a human being as well as a worker. Everyone produces just a bit more for someone they like. Leaders understand the way things work. They know money is not the only most motivating factor in the work life of most people.

    The true strength of leadership is an inner strength that comes from the confidence of Emotional Intelligence-knowing your own emotions, and how to deal with them and those of others. Developing your emotional intelligence is the best thing you can do if you want to develop your relationships with people around you, which is the key to the leadership skills.

    How's your happiness quotient (指数)? Science tells us that if you want to increase your "happiness quotient" every day, it's important to take time and accept the present blessings (恩赐) in your life.

    I wanted to share a moment of feeling about some of my blessings and what's in my life to be grateful for as Thanksgiving approaches.

    One of our family traditions at our Thanksgiving meal is to go around the table and to let each one share something we're especially thankful for.

    I'm going to recite lots of things, including that I'm grateful for my health, my loving husband, and the wonderful relationship we share. My husband joins me for 3-mile walk to start our day. The exercise habit keeps our moods in check and the ups and downs of life easier to manage. We talk as we walk, sharing ideas, worries and good feelings too. Sometimes we argue a little until we figure out what to do. We always come up with something. What a blessing that is!

    It is so much to be grateful for. I feel I am the luckiest woman alive. It's my wish for you that you'll be able to spot something in your life. I hope yet you will savor (体味) and appreciate it.

    Many of us spend the holiday with our aging parents or other loved ones. In my work at AgthgParents.com, we just reminded everyone that you never know if there will be another Thanksgiving with these loved ones. We can't take the day for granted. Just be in the moment. We suggest that you verbally give thanks to your parents, no matter what conditions your aging parents may be in now. Do what you can to be tuned in to what you need as well as what your family needs.
