When a child is told he is "uncool", it can be very painful. He may say he doesn't care, and even act in ways that are different from cool on purpose(故意地）. But these are simple ways to deal with sadness by pretending it's not there.

    Helping a child feel better in school had to be careful. If you say, "Why are you worried about what other children think about you? It doesn't matter!" Children know that it does matter. Instead, an active way may be best. You could say, "I'm going to do a couple of things for you to help you feel better in school."

    If a boy is having trouble making friends, the teacher can help him. The teacher can arrange things so that he has chances to use his abilities to contribute to class things. This is how the other children learn how to value his good qualities and to like him. A teacher can also raise a child's popularity in the group by showing that he values that child. It even helps to put him in a seat next to a very popular child, or let him be a partner with that child in activities, etc.

    There are things that parents can do at home, too. Be friendly when your child brings others home to play. Encourage him to invite friends to meals and then serve the dishes they consider "super" .When you plan trips, picnics, movies, and other shows, invite another child with whom your child wants to be friends.

    What you can do is to give him a chance to join a group that may be shutting him out. Then, if he has good qualities, he can start to build real friendship of his own.

    As computers become more popular in China, Chinese people are increasingly relying on computer keyboards to input (输入) Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes（笔画）of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.

    Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer.

    All the students interviewed say they usually use a computer.

    It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education.

    "When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it."

    "I'm not in the mood to write when faced with a pen and paper."

    Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?

    Many educators think differently. Shi Liwei, the headmaster of a famous primary school in the capital, said, "Chinese characters enjoy both practical and aesthetic（审美的）value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them."

    To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory（必修的）and in universities, some professors are asking students to turn in their homework and essays written by hand.

    No one is sure how the ancient Egyptians built the pyramids near Cairo. But a new study suggests they used a little rock 'n' roll. Long-ago builders could have attached wooden poles to the stones and rolled them across the sand, the scientists say.

    "Technically, I think what they're proposing is possible," physicist Daniel Bonn said.

    People have long puzzled over how the Egyptians moved such huge rocks. And there's no obvious answer. On average, each of the two million big stones weighed about as much as a large pickup truck. The Egyptians somehow moved the stone blocks to the pyramid site from about one kilometer away.

    The most popular view is that Egyptian workers slid the blocks along smooth paths. Many scientists suspect workers first would have put the blocks on sleds(滑板). Then they would have dragged them along paths. To make the work easier, workers may have lubricated the paths either with wet clay or with the fat from cattle. Bonn has now tested this idea by building small sleds and dragging heavy objects over sand.

    Evidence from the sand supports this idea. Researchers found small amounts of fat, as well as a large amount of stone and the remains of paths.

    However, physicist Joseph West thinks there might have been a simpler way, who led the new study. West said, "I was inspired while watching a television program showing how sleds might have helped with pyramid construction. I thought, 'Why don't they just try rolling the things?' "A square could be turned into a rough sort of wheel by attaching wooden poles to its sides, he realized. That, he notes, should make a block of stone "a lot easier to roll than a square".

    So he tried it.

    He and his students tied some poles to each of four sides of a 30-kilogram stone block. That action turned the block into somewhat a wheel. Then they placed the block on the ground.

    They wrapped one end of a rope around the block and pulled. The researchers found they could easily roll the block along different kinds of paths. They calculated that rolling the block required about as much force as moving it along a slippery(滑的)path.

    West hasn't tested his idea on larger blocks, but he thinks rolling has clear advantages over sliding. At least, workers wouldn't have needed to carry cattle fat or water to smooth the paths.

The Domestication （驯化）of Cats

    For centuries, the common view of how domestication had occurred was that prehistoric people, realizing how useful it would be to have animals kept for food, began catching wild animals and breeding （繁殖）them. Over time, by allowing only animals with "tame"（驯养）characteristics to produce their babies, human beings created animals that were less wild and more dependent upon people. Eventually this process led to the domestic farm animals and pets that we know today, having lost their ancient survival skills and natural abilities.

    Recent research suggests that this view of domestication is incomplete. Prehistoric human beings did catch and breed useful wild animals, but specialists in animal behavior now think that domestication was not simply something people did to animals—the animals played an active part in the process. Wolves and wild horses, for example, may have taken the first steps in their own domestication by hanging around human settlements, feeding on people's crops and getting used to human activity. The animals which were not too nervous or fearful to live near people produced their babies that also tolerated humans, making it easier for people to catch and breed them.

    In this version, people succeededin domesticating only animals that had already adapted easily to life around humans. Domestication required an animal that was willing to become domestic. The process was more like a dance with partners than a victory of humans over animals.

    At first glance, the laming of cats seems to fit nicely into this new story of domestication. A traditional theory says that after prehistoric people in Egypt invented agriculture and started farming, rats and mice gathered to feast on their stored grain. Wildcats, in tum, gathered at the same places to hunt and eat the rats and mice. Over time, cats got used to people and people got used to cats. Some studies of wildcats, however, seem to call this theory into question. Wildcats don't share hunting and feeding areas, and they don't live close to people. Experts do not know whether wildcats were partners in their own domestication. They do know that long after people had acquired domestic dogs, sheep and horses, they somehow acquired domestic cats. Gradually they produced animals with increasingly tame qualities.

Welcome to your future life!

    You get up in the morning and look into the mirror. Your face is firm and young­looking. In 2035, medical technology is better than ever. Many people at your age could live to 150, so at 40, you're not old at all. And your parents just had an anti­aging (抗衰老的) treatment. Now, all three of you look the same age!

    You say to your shirt, "Turn red." It changes from blue to red. In 2035, "smart clothes" contain particles (粒子) much smaller than the cells in your body. The particles can be programmed to change your clothes' color or pattern.

    You walk into the kitchen. You pick up the milk, but a voice says, "You shouldn't drink that!" Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.

    It's time to go to work. In 2035, cars drive themselves. Just tell your "smart car" where to go. On the way, you can call a friend using your jacket sleeve (袖子). Such "smart technology" is all around you.

    So will all these things come true? "For new technology to succeed," says scientist Andrew Zolli, "It has to be so much better that it replaces what we have already." The Internet is one example-what will be the next?

Tuesday, 1^st September

    I had mixed feelings today, nervous, worried, happy, excited… My heart went down when Miss Chan, our head teacher, said that Matthew and Beth, two students from England, would spend three months with us! I was worried that I had to speak English so much! But at the end of the school day, I was happier than I thought: the morning with them today was more enjoyable than I expected.

    Today is the most unforgettable first day I have had! Matthew is fantastic! His English is clearer and easier to listen to than I thought. The other English student, Beth, is the most helpful girl I've ever met. There were lots of things to do on the first day. Beth offered to help Miss Chan put up all the notices. Of course, some of the credit (功劳) should also go to ME because I translated some of the notices for her. Miss Chan praised us!

    We finished all the preparations 10 minutes earlier than expected, then Beth and I talked for a while, Matthew sang several English songs and did some stand-up comedy (单人喜剧表演) at the party. We all praised him. When the bell rang to end the first school day, none of us wanted to leave.

    When I went back home, I had a little headache. I have probably spoken more English today than the whole of last year.

    It was really a happy day! I hope our friendship can continue, even after they gone back to England!
