This Monday, the nation will start to celebrate Presidents' Day, just seven days before George Washington's birthday. Everyone agrees that day is a holiday. but is it just to celebrate George Washington's Birthday? What about Abraham Lincoln? Some government offices call it Presidents' Day. Others say the holiday is officially Washington's Birthday. Confused yet?

    George Washington was elected the country's first President on April 30,1789. Soon after, Americans began publicly celebrating his birthday. Presidential historians say the actual date of George Washington's birth is February 11,1732. But a change inthe calendar system 20 years later shifted all dates, making Washington's birthday February 22, which is now well accepted. In 1879. Congress made Washington's birthday an official federal holiday. It was the first federal holiday to celebrate an individual's birthday. In 1968, Congress passed the Monday Holidays Act, which moved the holiday to the third Monday in February. The new law did not change the holiday's name. It was still called Washington's Birthday, even though some law makers wanted to call it Presidents' Day to include Abraham Lincoln, whose actual birthday is February 12.

    Many people argue that the holiday should celebrate all past Presidents. They feel Lincoln should be honored for his role in preserving the nation during the Civil War and helping to free slaves. Others feelthe holiday should only honor Washington. the country's first President. They say shifting the focus away from Washington would mean future generations of kids would not know about the Father of Our Country.

    Laws have been introduced in Congress over the years to requireuse of the term “George Washington's Birthday.”but none of those laws have been passed. Meanwhile, many stategovernments and school districts now use the term “Presidents' Day．”Many stoles also use it to promote holiday sales.

    Cheating can happen in a lot of different ways. When people cheat, it's not fair to other people, like the kids who studied for the test or who were the true winners of a game.

Many people like the action of cheating. It makes difficult things seem easy, like getting all the right answers on the test. But it doesn't solve the problem of not knowing the material and it won't help on the next test — unless the person cheats again.

    Some people lose respect for cheaters and think less of them. The cheaters themselves may feel bad because they know they are not really earning that good grade. And, if they get caught cheating, they will be in trouble at school, and maybe at home, too.

    Some kids cheat because they're busy or lazy and they want to get good grades without spending the time studying. Other kids might feel like they can't pass the test without cheating. Even when there seems to be a “good reason” for cheating, cheating isn't a good idea.

    If you were sick or upset about something the night before and couldn't study, it would be better to talk with the teacher about this. And if you don't have enough time to study for a test because of swim practice, you need to talk with your parents about how to balance swimming and school.

    A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions together. Talking about these problems and working them out will feel better than cheating.

    When I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived on a farm, in the winter especially, we wear quite out off from the outside world. As soon as I left school, I packed my bags and moved to the capital.

    However, I soon discovered that one big disadvantage is money. It costs so much to go out, not to mention basics like food and housing. Another disadvantage is pollution. I suffer from asthma(哮喘), and the air is so bad that I am afraid to go outside. Then there is the problem of traveling round. Although I have a car, I seldom use it because of the traffic jams. One choice is to go by bicycle, but that can be quite dangerous.

    Of course there are advantages. First, there is so much to do in the city, whatever you tastes in culture or entertainment(娱乐活动). Besides, there are wonderful jobs and greater chances of moving to a more important job or position. Finally, if you like shopping, the variety of goods is very surprising — and, what is more, shops are often only a short walk away.

    Is life better then, in the city? Perhaps it is, when you are in your teens(十几岁) or twenties. However, as you get older, and especially if you have small children, the peace of the countryside may seem preferable. I certainly hope to move back there soon.

    A telescope, called Gaia, is being designed by astronomers in Europe, and it couldn't be more different from Pan-STARRS, which is another telescope being designed. While Pan-STARRS will be looking for asteroids (小行星) and comets headed for Earth, Gaia will be looking at our entire galaxy (银河系).

    Gaia is designed to draw a map of the Milky Way, our home galaxy. Just as a map of your town gives you a picture of where things are located, Gaia's map of the galaxy will tell astronomers where the stars are. Over five years, Gaia will observe (观察) about a billion stars and other objects in our galaxy. Each object will be observed about 70 times.

    Gaia will be sent into space connected to a rocket. It contains two telescopes, each focused at a different angle (角度). These two telescopes act like Gaia's “eyes”. The reason why humans can see things in 3D is that we have two eyes focused on the same object, at slightly different angles. By using two telescopes like eyes, Gaia can produce the first 3D map of the positions of the stars it views.

    Gaia, which is to be sent into space, will be a powerful telescope. If you were to use it on Earth, for example, you could stand 600 miles away from your best friends and still get a clear picture of their hair.

    Gaia is one of more than a dozen telescopes being designed by scientists right now. The next generation of telescopes will reveal new parts of our universe that will seem surprising. The universe, with all its planets, stars and other strange objects, is a puzzle with pieces that we can see by using powerful telescopes.

    Jim suffered heart problems. In conversation he expressed little joy and it seemed that his life was drawing to a close.

    When his heart problems led to operation, Jim went through it successfully, and a full recovery was expected. Within days, however, his heart was not beating properly. Jim was rushed back to operation, but nothing was found to explain the cause of his illness. He died on the operating table on the day before his 48th birthday.

    Dr. Bruce Smoller, a psychologist(心理学家), had had many conversations with him, and the more he learned, the stranger he realized Jim's case was. When Jim was a child, his father, a teacher, suffered a heart attack and stayed home to recover. One morning Jim asked his father to look over his homework, promising to come home from school at noon to pick it up. His father agreed, but when Jim returned his father had died. Jim's father was 48.

    "I think all his life Jim believed he killed his father," Dr. Smoller says. "He felt that if he had not asked him to look at his homework, his father would have lived. Jim had been troubled by the idea. The operation was the trial(判决) he had expected for forty years." Smoller believes that Jim willed himself not to live to the age of 48.

    Jim's case shows the powerful role that attitude(态度) plays in physical health, and that childhood experiences produce far-reaching effect on the health of grown-ups. Although most cases are less direct than Jim's, studies show that childhood events, besides genes, may well cause such midlife diseases as cancer, heart disease and mental illness.

    A few hours after my first mission, returning to Earth on the space shuttle Endeavour, I completed all of my medical tests after flight, met with NASA officials, and reunited with my family. Finally, I was alone in my office room in astronaut crew quarters at the Kennedy Space Center, exhausted and ready for bed. And I did what anyone does when they return to their hotel room on a business trip: I turned on the TV. The television news started up: Such and such had happened, people were shocked, blah blah blah. Sports scores. Silly commercials.

    It didn't take more than a minute before I had to turn it off. It felt like my body was rejecting all this input, just as it would reject an organ donation that had the wrong blood type. All of this noise was just completely foreign to who I was—or, more appropriately, who I had become. A few hours before, I had been orbiting Earth, seeing our planet from space, flying the most amazing machine ever built by human hands, working with a team that was the absolute success of human. And now here in my room watching what was being sold as news, and with my newfound perspective, I just could not stomach it. My worldview was changed forever in a profound (深刻的) way.

    The biggest change by far and the one for which I will always be most grateful is this big-picture perspective. That will stick with me for the rest of my life.

    Whenever I feel the pressure of modern life, the stress about work, or worry about the future, I remember my time in the space station. Back to seeing the sun set Or watching our galaxy rise on the horizon. Or seeing a sea of lightning flash a hundred times a second. Or simply back to floating weightlessly.

    When I'm there in my mind and realize how many billions of these beautiful sunsets there have been and will be in the future, the cares of the world just don't seem that pressing. It goes that, "Do not worry about tomorrow, for tomorrow will worry about itself." Living daily life down here on the planet is so much better with this attitude!
