    LONDON－Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets (彗星) in the direction of Earth, and its orbit will be changed too. Our world will then be sent spinning into a safer, colder part of the solar system.

    This idea for improving our climate comes from a group of U. S. National Aeronautics and Space Administration (NASA) engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet－effectively doubling its working life.

    The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.

    “Earth's orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.

    Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.

    In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The Sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere (生物圈) －by cooking us.

    That's why the group decided to try to save Earth.

    The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation (误算) in orbit could fire it straight at Earth--with deadly consequences.

    There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is “most likely the Moon would be stripped away from Earth”. This would greatly change our planet's climate.

    Last year I was put into a lower­level math class at school. The reason I was in this class had nothing to do with my intellect (智力) or maths skills. I am blind.

The only problem with being in this class was that I was surrounded by “at­risk” students. These were kids who did not do well in school and they were constantly in trouble with the school and the law.

    One Tuesday morning, I went to a Christian Student Union meeting before school. There was a guest speaker there that day talking to us about praying (祈祷) for our enemies. I began to think about this. As I considered the idea, I prayed and asked God how I could pray for the kids in my class. I had forgotten that they weren't bad kids; they were just lost.

    At first, the prayers were mechanical. When I would hear their voices in class, I would pray, “Dear God, please bless so­and­so...” But as I continued, I began to think of the kids more often, and in my quiet time at home I would ask God to bless (保佑) the rest of my classmates.

    As time went on, my classmates became more than just annoying kids to me. There was something growing inside my heart for them, something that wasn't there before. They began to feel like family, and I was learning to love them in a way I never thought possible.

    I now see that praying is such a powerful act. Prayer is the most powerful tool a Christian has. When I pray for those around me, it also blesses my life, and it changes my opinion of others. I realized I needed God's blessings to see the world through loving eyes. The prayers I said for others turned out to help me the most.

    So many of us hold on to little complaints that may have come from an argument, a misunderstanding, the way we were raised, or some other painful events. Stubbornly, we wait for someone else to reach out to us—believing this is the only way we can forgive or rekindle a friendship or family relationship.

    A friend of mine, recently told me that she hadn't spoken to her son in almost three years. She said that she and her son had had a disagreement about his wife and that she wouldn't speak to him again unless he called first. When I suggested that she be the one to reach out, she said, “I can't do that. He's the one who should apologize.” After a little gentle encouragement, however, she did decide to be the first one to reach out. To her amazement, her son was grateful for her willingness to call and offered an apology of his own. As is usually the case when someone takes the chance and reaches out, everyone wins.

    Whenever we hold on to our anger, we turn “small stuff(问题)” into really “big stuff” in our minds. We start to believe that our positions are more important than our happiness. They are not. If you want to be a more peaceful person you must understand that being right is almost never more important than allowing yourself to be happy. The way to be happy is to let go, and reach out. Let other people be right. This doesn't mean that you're wrong. Everything will be fine. You'll experience the peace of letting go, as well as the joy of letting others be right.

    You'll also notice that, as you reach out and let others be “right” they will become less defensive and more loving toward you. They might even reach back. But, if for some reason they don't, that's okay too. You'll have the inner satisfaction of knowing that you have done your part to create a more loving world, and certainly you'll be more peaceful yourself.

    At first glance Esther Okade seems like a normal 10-year-old. She loves dressing up, playing with Barbie dolls and going to the park or shopping. But what makes the British-Nigerian youngster stand out is the fact that she's also a university undergraduate.

    Esther, from Walsall, an industrial town in the UK's West Midlands region, is one of the country's youngest college freshmen. The talented 10-year-old enrolled at the Open University, a UK-based distance learning college, in January and is already top of the class, having recently scored 100% in a recent exam.

    "It's so interesting. It has the type of maths I love. It's real maths-theories, complex numbers, all that type of stuff," she smiles. "I want to finish the course in two years. Then I'm going to do my PhD in financial maths when I'm 13. I want to have my own bank by the time I'm 15 because I like numbers and I like people and banking is a great way to help people." she adds.

    Esther has always jumped ahead of her peers. She sat her first Math GSCE exam, a British high school qualification, at Ounsdale High School in Wolverhampton at just six, where she received a C-grade. A year later, she got the A-grade she wanted. Then last year she scored a B-grade when she sat the Math A-level exam.

    Not content with breaking barriers to attend college at just 10 years old, Esther is also writing a series of math workbooks for children called "Yummy Yummy Algebra."

    "It starts at a beginner level-that's volume one. But then there will be volume two, and volume three, and then volume four. As long as you can add or subtract, you'll be able to do it. I want to show other children they are special." she says.

    Aruba is one of the most well-known Caribbean destinations for tourists around the world.

    You're probably wondering what to include as well as what to wear while you're in Aruba.

    Clothes

    The main reason why you're heading there is to relax on the country's fresh beaches and joy in warm waters of the Caribbean Sea. During most of the day, you'll likely be wearing your swimsuit. When you're finished at the beach or pool area, it is advisable to bring along a shirt or cover as well as shorts to wear.

    It is not recommended to wear beach clothes when you go out for dinner – regardless of the time of day. Shorts and T-shirts are enough in many restaurants, although more formal clothes are advised for the fanciest eating establishments.

    What else to bring?

    The Caribbean sun is very strong and if you're planning on spending lots of time in the sun, there are several precautions you must take. Include suncream, sunglasses, a wide hat, a couple of bathing suits, as well as a beach bag and a cooler in your luggage.

    What NOT to bring?

    While drinking water is questionable or not safe in many Caribbean nations, Aruba is an exception. Aruba is known for having the cleanest water in the world. There is no need to bring water, simply bring along an empty bottle.

    Several items are prohibited in Aruba for carrying. These include firearms, e-cigarettes, as well as sharp objects and tools.

    William Butler Yeats, a most famous Irish writer, was born in Dublin on June 13, 1865. His childhood lacked the harmony that was typical of a happy family. Later, Yeats shocked his family by saying that he remembered "little of childhood but its pain". In fact, he inherited (继承) excellent taste in art from his family — both his father and his brother were painters. But he finally settled on literature, particularly drama and poetry.

    Yeats had strong faith in the coming of new artistic movements. He set himself the fresh task in founding an Irish national theatre in the late 1890s. His early theatrical experiments, however, were not received favorably at the beginning. He didn't lose heart, and finally enjoyed success in his poetical drama.

    Compared with his dramatic works, Yeats's poems attract much admiring notice. The subject matter includes love, nature, history, time and aging. Though Yeats generally relied on very traditional forms, he brought modern sensibility to them. As his literary life progressed, his poetry grew finer and richer, which led him to worldwide recognition.

    He had not enjoyed a major public life since winning the Nobel Prize in 1923. Yet, he continued writing almost to the end of his life. Had Yeats stopped writing at age 40, he would probably now be valued as a minor poet, for there is no other example in literary history of a poet who produces his greatest works between the ages of 50 and 75. After Yeats's Death in 1939, W. H. Auden wrote, among others, the following lines:

    Earth, receive an honoured guest:

    William Yeats is laid to rest.

    Let the Irish vessel (船) lie

    Emptied of its poetry.
