The kids in this village wear dirty, ragged clothes. They sleep beside cows and sheep in huts made of sticks and mud. They have no school. Yet they all can chant the English alphabet, and some can make words.

    The key to their success: 20 tablet computers(平板电脑) dropped off in their Ethiopian village in February by a U.S. group called One Laptop Per Child.

    The goal is to find out whether kids using today's new technology can teach themselves to read in places where no schools or teachers exist. The Massachusetts Institute of Technology researchers analyzing the project data say they're already amazed. “What I think has already happened is that the kids have already learned more than they would have in one year of kindergarten,” said Matt Keller, who runs the Ethiopia program.

    The fastest learner—and the first to turn on one of the tablets—is 8-year-old Kelbesa Negusse. The device's camera was disabled to save memory, yet within weeks Kelbesa had figured out its workings and made the camera work. He called himself a lion, a marker of accomplishment in Ethiopia.

    With his tablet, Kelbasa rearranged the letters HSROE into one of the many English animal names he knows. Then he spelled words on his own. “Seven months ago he didn't know any English. That's unbelievable,” said Keller.

    The project aims to get kids to a stage called “deep reading,” where they can read to learn. It won't be in Amharic, Ethiopia's first language, but in English, which is widely seen as the ticket to higher paying jobs.

    Most of us have quite good memories, but our memories are limited. For example, we cannot remember everyone we have ever met or what we did on every single day of our lives. However, there are some people who do have prodigious memories. These people have a rare condition known as savant syndrome（学者症候群）. Savants suffer from a developmental disorder, but they also exhibit great talents that contrast（显出差异）sharply with their physical and mental disabilities.

    Kim Peek (1951-2009) was a savant who lived in Salt Lake City, Utah, in the United States. He was born with damage to parts of his brain, but it seemed that other parts of his brain, particularly those relating to memory, became over-developed.

    Peek's unique abilities appeared at a very early age. When he was just 20 months old, he could already remember every book that was read to him. Peek could read two pages of a book at the same time-one page with the right eye and one with the left-in less than 10 seconds and remember everything he read. By the time he died, Peek had memorized more than 9,000 books. He could remember all the names and numbers in a variety of telephone books. He could remember thousands of facts about history, literature, geography and sports.

    Dr. David Treffert, an expert on savant syndrome, once described Peek as “a living Google” because of his astonishing ability to memorize and connect facts. However, at the same time, Peek was unable to carry out simple tasks, such as brushing his hair or getting dressed, and he needed others to help him. In 1989, the movie Rain Man won the Oscar for best Picture. The main character in the movie, played by Dustin Hoffman, was based on Kim Peek's life. He started to appear on television, where he would amaze audiences by correctly answering difficult questions on different topics. Peek-became world famous, and he and his father began touring widely to talk about overcoming disabilities. He inspired a great many people with his words. “Recognizing and respecting differences in others, and treating everyone in the way you want them to treat you, will make our world a better place for everyone. Everyone is different.”

    Do you worry about entering senior high school? Everything, from study to environment, has changed. Can you adapt yourself to it?

    You're not alone. Remember that everybody else in your year is in the same boat. You may not notice it, but they're just as nervous as you are.

    Moving to senior high school is a chance, not a problem. Things are different, and all you need to do is to be polite and learn the new rules.

    The teachers will help. If you don't know what to do or are worried about something, then ask for help. Teachers are probably the best people to turn to, because they have experience in helping new students. Pay attention to what your teachers say.

    Everything changes. There are lots of differences between junior high school and senior high school. You will have your lessons with different teachers in different rooms. You will have homework for different subjects on different days, so make sure you get organized. Make sure you know which rooms your classes are in and which days you have your different subjects on.

Other points:

    If you've got an older brother or sister at the school, then ask them for advice.

    Be yourself! It sounds simple, but things will become better if you just act naturally.

    Having early nights makes a difference. You'll also find it easier to get up in the morning!

    You may probably meet most of the powerful graduation speakers, here who are well-known people in their fields. I think the schools couldn't have picked better speakers than them, because they set good examples, deeply inspiring us in our daily life.

    1) Steve Jobs, Stanford University:

    "Remembering you're going to die, and the best way I know is to avoid the trap of thinking that you have something to lose. There is no reason not to follow your heart. Your time is limited, so don't waste it living someone else's life. Don't let the noise of others' opinions drown out your own inner voice... "

    2) Oprah Winfrey, Stanford University:

    "I consider the world, this Earth, to be like a school... And the secret I've learned to get ahead is being open to the lessons from the grandest universe of all. Don't react against a bad situation. And the solution will arise from the challenge. So don't give up easily, acting with responsibility... "

    3) Bono, University of Pennsylvania:

    "For four years you've been buying, trading, and selling everything you've got in this market-place of ideas. Your pockets are full, even if your parents' are empty, and now you've got to figure out what to spend it on... The world is more flexible than you think and it's waiting for you to hammer it into shape... "

    4) Michael Dell, University of Texas at Austin:

    "Now it's time for you to move on to what's next and obtain your desire. But you must not let anything prevent you from taking those first steps. Don't spend so much time trying to choose the perfect opportunity, or sometimes you'll miss the right opportunity. Recognize that there will be failures and obstacles. But you will learn from your mistakes and the mistakes of others."

    Young mums shopping in the Copley Mall in downtown Boston-month found themselves being questioned about their use of soap by students from Harvard Business School usually known as HBS. The students were not doing odd jobs to earn beer money. They were preparing to help a firm in Brazil launch an antibacterial cleanser.

    The 900 students arriving in Boston this summer for their two-year course were told that they would be subjects. The new practical addition to HBS's curriculum is known as "FIELD" that stands for Field Immersion Experiences for Leadership Development. Fieldwork — ie, going out and talking to people — is a big change for HBS.

    Not all the staff and students were overjoyed to be experimented on. But the man responsible, Nitin Nohria, head of HBS, says that "If it works, the FIELD method could become an equal partner to the case method."

    What happens in the second year of the new course is still being worked out. But the first year has three elements. First, team-building exercises. Students take turns to lead a group engaged in a project. They learn to cooperate and to give and take feedback. Second, students will be sent to work for a week with one of more than 140 firms in 11 countries. In the third part of the course, students will be given eight weeks, and seed money of ＄3,000 each, to launch a small company. The most successful, as voted by their fellow students, will get more funding. The experiment does not come cheap, adding 5-10% to the course's cost, which HBS will bear while it figures out what works.

    A new study suggests that patients with breast cancer who take additional vitamins during chemotherapy(化疗) treatment may face increased risks.

    Researchers said the use of dietary supplements(补充剂) that increase levels of antioxidants, iron, vitamin B12 and omega-3 fatty acids appeared to lower the effectiveness of chemotherapy. Researchers reported their findings in the Journal of Clinical Oncology.

    Christine Ambrosone is the head of cancer prevention and control at the Roswell Park Comprehensive Cancer Center in Buffalo, New York. She said, "From this study and others in the literature, it seems that it may not be wise to take supplements during chemotherapy."

    "It's thought that antioxidants might interfere with the ability of chemotherapy to kill cancer cells," Ambrosone said.

    Some doctors have been advising patients for a number of years not to take antioxidants during chemotherapy. "But there was no strong empirical data for that recommendation," Ambrosone said.

    So, Ambrosone and other researchers decided to study whether supplement use might affect chemotherapy's effectiveness. They looked for evidence in an earlier study on diet, exercise, lifestyle and cancer results.

    In the earlier research, people who took part were asked about their use of supplements at the beginning of and during treatment, and about their lifestyle, diet and exercise. The researchers studied 1,134 patients who filled out the surveys and followed them for a median of six years.

    The researchers searched for possibilities that might increase the risk of the disease reappearing or of death. They found that patients who took any supplements at the beginning of and during chemotherapy were 41 percent more likely to have their breast cancer return than those who did not. In addition, the supplement takers were 40 percent more likely to die later on compared to patients using no supplements. The supplements included vitamin A, C and E. Those taking vitamin B12 and iron supplements were at greater risk of cancer returning, the researchers said.
