    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.

How to remember your passwords

    Remembering and then forgetting your passwords can be a frustrating business, and one that contributes to more than half of calls made to helplines. {#blank#}1{#/blank#} Once you have reset your password, you're going to need to remember that one too. Follow our tips on breaking the password-frustration cycle.

    We often create so many user IDs but there are only a small number of passwords that you really need to remember. It's important for you to remember your banking and email passwords, but do you really need to worry about your occasional eBay visit? If you can commit(交付) just a few to memory, you can hand the rest over to a password keeper to do the remembering for you.

Sign up for a password keeping service.

    {#blank#}3{#/blank#} You just need to encrypt(加密) your data and keep it in a safe server. Many password keepers require you to remember just one master password, which will give you access to the accounts you have chosen.

Write them down

    “Just keep them in a safe place, such as a locked box,” says Internet security blogger Bruce Schneider. {#blank#}4{#/blank#} Thus, it isn' t entirely discouraged and can be an efficient back-up plan when all else fails.

Work on your memory

    {#blank#}5{#/blank#} Practicing memory techniques or making certain lifestyle changes, including reducing stress, might just prevent you from having to make that frustrating password phone call ever again.

    The first week of my summer campaign has been quite an experience! I'm learning the ups and downs of guiding this new journey,and I'm soon finding my footing in the wonderful world of support raising.

    Some may ask: Why do you choose a job where support raising is necessary? Why not just find a ministry that will support you without having to do any extra work?

    I had a wonderful support meeting this week where I was able to have some very good conversations with the lady I was sharing with.It blessed my soul to see her eyes light up with the same passion（热情）I felt in my heart about the ministry I was sharing with her.I kept thinking in my head "I've shared my passions with her,and she gets it."At the end of our meeting she decided to become a donor,but she gave me something extra that I haven't received from anyone else.She gave me a handmade wooden cross,small enough to carry with me.

    As soon as she handed it to me,I knew it was a gift sent from God,through an act of friendship.It's a symbol of a partnership that is developing through this journey,a symbol of how God can send us messages and a symbol of new friendships to come throughout the summer and my time in the middle east.Finally,it's a symbol of the example of what it looks like to build relationships with people who will join you in sharing with the world.It's something I'll treasure through the rest of my summer campaign,through my service in the middle east,and the rest of my life.

    It was the day after Halloween when my grandmother was admitted to the hospital with the worst headache she'd ever had. While posing in our costumes the night before, we knew something was wrong, just not how wrong.

    Grandma's house was the central gathering place of my family. Sunday lunches, birthday dinners, Easter, Thanksgiving, and Christmas — all were our traditions, with her as hostess. While my parents were busy running their small business, there were many nights when Grandma fed me and put me to bed in her spare room, until they came to get me. I spent my summers at Grandma's and I went everywhere with her. I couldn't imagine a time when she wouldn't be around me.

    Then November 1,1991 began her month-long stay in the hospital—she suffered from a rare infection (感染)called nocardia asteroides. After being born in the year of the Great Depression, living through World War II, raising three kids, and being widowed at the age of 48, Grandma never expected to live into her seventies. The infection in her brain seemed to confirm that she wasn't long for this world. But that's not the end of her story. A team of doctors successfully removed the abscess(脓肿), and Grandma even made it into a local medical journal. Her doctor called her “the brain lady”.

    Grandma celebrated her 85th birthday in March this year. In the almost 23 years since her recovery, she's seen two of her four grandchildren get married and welcomed three great-grandsons. Although they damage something in her house, she loves it when my two boys come over. And while I know they make her day, seeing her love blossom for another generation makes my day too. Happy Grandparents' Day to my amazing grandmother!

    I study English literature at university and have always been proud of Britain's literary heritage（文学遗产）. Some British authors that you may have heard of are Charles Dickens and Jane Austen. These writers are famous all over the world because their books have been translated into many different languages. In the UK, their novels are celebrated as some of the best that have ever been written. We say that these novels are “classic” because they are still read and enjoyed years after their publication.

    I read classic novels because they are part of my university lessons but also because I enjoy them. They can teach you a lot about how people used to live and what society was like in the past. Novels like Hard Times by Charles Dickens remind us of the poverty in London during the Industrial Revolution while Jane Austen's fiction shows us what family life was like in the 18th century.

    Classic novels usually have memorable stories land interesting characters. One of my favourite books is Charles Dickens Great Expectations. It is about a boy called Pip who suddenly receives a lot of money from a mysterious supporter. As he grows up, his character changes: he becomes quite selfish and mean. Another important character is Miss Havisham. When she was young, her fiancé ran away on their wedding day. She lives in a dark house and still wears her wedding dress. She is a fascinating character, both sad and scary.

    Reading classic novels enriches my knowledge and life experience. And it has become part of life.
