What would it be like to walk on Mars? If you could build the highest building in the world，what would it look like? Do you dream of being the next J. K. Rowling? This summer, you can experience all of these things, and more. All you need is an Internet connection and your imagination.

    A recent study by the Kaiser Family Foundation found that kids spend an average of 1 hour and 29 minutes online each day. Many kids like to use that time to chat with friends, play games or check e­mails. But the next time you get on the Web, try exploring the world instead. “With the Internet，you can go back 11,000 years in time，or go 11,000 kilometers across the planet.” said Russell, Web search expert of Google. “The whole scope of history and the world is open to you.”

    There is a wealth of information to be found online. For example, if your family is going on vacation somewhere, do a quick online search on the area before you even get in the car. “What's the background of the place; what's the history？” says Russell. “I like to tell my kids, ‘Whenever you have a question, whenever you have a doubt, search it out.'”

    Ready to launch a virtual journey of your own? Here are a few starting points to get you thinking and to help you on your way. You can invite your parents along for the ride, too. Always ask for permission before downloading programs and software onto your computer. And check with a parent or an adult before visiting any new Web site.

    Navigate the world in 3­D with Google Earth. Begin in outer space and zoom (快速移动) into the streets of any city, from Hong Kong to San Francisco. Or visit ancient monuments, watch the changing rainforests over time, and dive underwater to explore tropical reef.

    With the Moon in Google Earth tool, you can walk in Neil Armstrong's famous footsteps. Take a guided tour of the moon's surface with Armstrong's fellow shuttle mate astronaut Buzz Aldrin.

    When you're exploring that part of the solar system, hop on over to the Red Planet with Google Mars. There, you can move very quickly around the surface and see images from the Mars Rovers.

    Going green seems to be fad(时尚)for a lot of people these days.Whether that is good or bad，we can't really say, but for the two of us，going green is not a fad but a lifestyle．

    On April22nd，2011，We decided to go green every single day for an entire year．This meant doing 365 different green things，and it also meant challenging ourselves to go green beyond easy things．Rather than recycle and reduce our energy, we had to think of 365 different green  things to do and this was no easy task．

    With the idea of going green every single day for a year .Our Green Year started．My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment．We wanted to push the message that every little bit helps．

    Over the course of our Green Year, we completely changed our lifestyle．We now shop at organic(有机的) stores．We consume less meat, choosing green food．We have greatly reduced our buying we don't need．We have away half of what we owned through websites．Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made flesh bread .In our home office anyone caught doing something ungreen might be punished．

    Our minds have been changed by Our Green Year．We are grateful for the chance to have been able to go green and educate others .We believe that we do have the power to change things and help our planet．

    Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.

    How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.

    “More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers' bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.

    Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.

    Black Friday-the day after Thanksgiving Day in the United States-signals the beginning of the holiday shopping season. Although it's not an official holiday, millions of employers give their employees the day off, and many people use that day to get a jump start on their holiday shopping. A similar day in Canada and the Great Britain is called "Boxing Day".

    Black Friday has become a marketing sensation in recent years. Since 2005, it has been the busiest shopping day of the year. To lure shoppers, retailers（零售商）routinely open their doors as early as 4 am and offer special sales and promotions to the shoppers that arrive early. Some of the special deals offered by stores are only available in limited quantities. That is why some shoppers intend on getting the best deals often camp out in front of stores overnight so that they will be the first in line when the doors open.

    But why Black Friday? Historians believe the name started in Philadelphia in the mid 1960s. Bus drivers and police used "Black Friday" name. In the early 1980s, a more positive explanation of the name began to ciculate. According to this alternative explanation, Black Friday is the day when retailers finally begin to turn a profit for the year. In accounting terms, operating at a loss is called being "in the red" because accountants traditionally used red ink to show negative amounts. Positive amounts were usuallay shown "in black ink". Thus, being in the black is a good thing because it means stores are operating at a profit.

    Recently, for those who are too busy to stop on Black Friday, or who just don't want to fight the crowds, the Monday following Black Friday has become known as Cyber Monday for shoppers can take advantage of the comfort of getting many online deals from their homes.

    Ninety years ago a man named Howard Carter made a great find. But he didn't discover an unknown people group or a new plant. He found the resting place of a king.

    People had seen signs of King Tutankhamun's tomb (坟墓) but had never found it. Finally, Carter's team discovered a set of steps that led down to some underground rooms. There Carter found the king's body and many of his treasures.

    Carter recorded his first impression in his popular book, The Tomb of Tut-Ankh-Amen：

At first I could see nothing, the hot air coming from the room causing the candle light to flicker (闪烁), but later, as my eyes grew used to the light, details of the room within appeared slowly and clearly, strange animals and gold—everywhere the light of gold... I was struck speechless with amazement, and when Lord Carnarvon, unable to stand the silence any longer, asked anxiously,  “Can you see anything?” it was all I could do to get out the words, “Yes, wonderful things.”

    The discovery has made King Tutankhamun, Tut for short, one of the best-remembered kings of Egypt. Tut became king when he was only 9 years old and ruled ancient Egypt from 1332 to 1323 B.C. No one is sure why, but he died suddenly before he turned 20. Because he died so young, there wasn't time to prepare a great tomb for him. So he ended up with a smaller tomb. Its small size was actually the reason why it stayed hidden for so long. And, Tut's tomb was not like other Egyptian kings'—it was not as damaged by time or robbers as other tombs. King Tut's tomb remains the best-kept royal (皇室的) tomb ever discovered. The discovery of this little tomb has helped people learn a great deal about ancient Egypt.
