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 accompli shment 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.

    The year was 1932. Amelia Earhart was flying alone from North America to England in a small single-engined aeroplane. At midnight, several hours after she had left Newfoundland, she ran into bad weather. To make things worse, her altimeter (高度表) failed and she didn't know how high she was flying. At night, and in a storm, a pilot is in great difficulty without an altimeter. At times, her plane nearly plunged (冲) into the sea.

    Just before dawn, there was further trouble. Amelia noticed flames coming from the engine. Would she be able to reach land? There was nothing to do except to keep going and to hope.

    In the end, Amelia Earhart did reach Ireland, and for the courage she had shown, she was warmly welcomed in England and Europe. When she returned to the United States, she was honored by President Hoover at a special dinner in the White House. From that time on, Amelia Earhart was famous.

    What was so important about her flight? Amelia Earhart was the first woman to fly the Atlantic Ocean alone, and she had set a record of fourteen hours and fifty—six minutes.

    In the years that followed, Amelia Earhart made several flights across the United States, and on each occasion (时刻) she set a new record for flying time. Amelia Earhart made these flights to show that women had a place in aviation (航空) and that air travel was useful.

    The University of Tokyo has eight museums covering various fields such as medicine, agriculture and art. Click the names of the museums below to read brief introductions about their histories and exhibits.

    The University Museum

    Having accumulated over three million academic materials for its collection since the University of Tokyo was founded in 1877, the University Museum is the largest museum of its kind in Japan. From the time of its reorganization into an independent entity in May 1996, the Museum has held exhibitions over 60 times.

    The Museum of Health and Medicine

    The Museum of Health and Medicine seeks to provide information about health and medicine to the general public and advance education for students studying medicine. The Museum features both a permanent and a temporary exhibition space and a temporary exhibition space, with the latter focusing on topics related to medical care and the study of medicine.

    The Agricultural Museum

    The Agricultural Museum displays materials from the collection of the University's Graduate School of Agricultural and Life Science, Notable items on display include the documents and portraits of scientists affiliated (隶属的)with the University, internal organs of Japan's famous dog Hachiko, and drawings illustrating German agriculture and the varieties of Japanese cows.

    The Farm Museum

    The Farm Museum opened in 2007 within a renovated dairy bam. The bam was built in 1934 as part of the moving of the University of Tokyo's farm from Komaba to Tanashi, an area in Western Tokyo. The Museum features both permanent and temporary exhibitions. Permanent exhibitions include European farming equipment used on the Komaba Farm, tools for agricultural experiments, agricultural machinery, American tractors and drawings illustrating German agriculture.

    I must have always known reading was very important because the first memories I have as a child deal with books. There was not one night that I don't remember mom reading me a storybook by my bedside. I was extremely inspired by the elegant way the words sounded.

    I always wanted to know what my mom was reading. Hearing mom say," I can't believe what's printed in the newspaper this morning," made me want to grab it out of her hands and read it myself. I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.

    This is how everyone learned to read. We would start off with sentences, then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said," The C-A-N-D-Y is hidden on the top shelf," I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything. I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.

    Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A's on my tests. Occasionally, I would read a novel that was assigned, but I didn't enjoy this type of reading. I liked facts, things that are concrete. I thought anything abstract(抽象的) left too much room for argument.

    Yet, now that I'm growing and the world I once knew as being so simple is becoming more complex, I find myself needing a way to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new character. In these worlds I can become anyone. I don't have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.

    We're taught to read because it's necessary for much of human understanding. Reading is a vital part of my life. Reading satisfies my desire to keep learning. And I've found that the possibilities that lie within books are limitless.

    Nature calms our stressed-out soul. Nature is the best medicine, but new research is showing how little time we need to set aside to harvest the benefits.

    In one new study, researchers tried to find the most effective "dose" (药剂) of nature within the context of normal daily life. As more doctors prescribe (开药方) nature experiences for stress relief and other health benefits — sometimes referred to as a "nature pill"— the study's authors hoped to make the details of these treatments clear.

    "We know that spending time in nature reduces stress, but until now it is unclear how much is enough, how often to do it, or even what kind of nature experience will benefit us," says lead author MaryCarol Hunter in a statement. "Our study shows that for the greatest payoff, in terms of efficiently lowering levels of the stress hormone cortisone (压力荷尔蒙激素), you should spend 20 to 30 minutes sitting or walking in a place that provides you with a sense of nature."

    A nature pill can be a low-cost, low-risk way to curb the negative effects of urbanization and indoor lifestyle. To find the most efficient dosage, Hunter and her co-authors asked 36 city citizens to have nature experiences of at least 10 minutes three times per week over eight weeks.

    Every two weeks, the researchers collected saliva (唾液) samples to measure levels of the stress hormone cortisone, both before and after the participants took a nature pill. The data showed that just a 20-minute nature experience was enough to significantly reduce cortisone levels. The effect was more efficient between 20 and 30 minutes, after which benefits continued to increase but at a slower rate.

    That fits with the findings of another recent study, which found that spending 20 minutes in an urban park can make you happier, no matter whether you use that time to exercise.

    For this study, 94 adults visited 3 urban parks in Mountain Brook, Alabama, completing a questionnaire about their subjective well-being before and after their visit. An accelerometer (加速计) tracked their physical activity.

    A visit lasting 20 to 25 minutes showed the best results, with a roughly 64% increase in the participants' self-reported well-being, even if they didn't move a great deal in the park. That last point is particularly positive, since it means anyone can benefit from visiting a nearby park, whatever his or her age or physical ability.

    "There is increasing pressure on green space within urban settings," said a UAB professor Gavin Jenkins. "Planners and developers look to replace green space with residential (住宅的) and commercial property. The challenge facing cities is that there is increasing evidence about the value of city parks but we continue to see the disappearance of these spaces."

Dear Mr.ing,

    I'm Bob Watson, one of the customers in your grocery store. I'm writing to express my idea about your goods.

    Your Supermart is outstanding in many ways. First I enjoy the selection of produce and fresh bakery items. Second your low prices and excellent customer service keep me coming back to Supermart. I have found, however, that I must make a separate shopping trip to one of your competitors because there are many items your store does not carry. This becomes inconvenient for me, as my time is valuable, and I don't like to make two trips. I have been a long time Supermart shopper and hope to continue for many years. If I could find all the items I need in one place, I would be a more satisfied customer.

    Specifically, I have never been able to purchase nacho cheese soup at your store. I can find other flavors (味道) of soup, but your store does not carry nacho cheese soup, a common ingredient (原料) in many of my recipes. In addition, I can only find large wonton wrappers, while many other stores carry both large and small and offer a more varied selection for their customers. Another example is Regent Brand Chili Seasoning. Though it is not a leading brand, it is still common on the shelves of other grocery stores in this area and is superior in flavor to its competitors.

    I sincerely hope to continue a relationship with your store, and I hope that you will consider the possibility of expanding your goods to be more competitive.

Yours truly,

Bob Watson
