Arriving in Sydney on his own from India, my husband, Rashid, stayed in a hotel for a short time while looking for a house for me and our children.

    During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.

    He reported the case to the police and then sat there, lost and lonely in the strange city, thinking of the terrible troubles of getting all the paperwork organized again from a faraway country while trying to settle down in a new one.

    Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband's name and was asking him a lot of questions. Then he said they had found a pile(堆) of papers in their trash can(垃圾桶) that had been left out on the footpath.

    My husband rushed to their home to find a kind family holding all his papers and documents(文件). Their young daughter had gone to the trash can and found a pile of unfamiliar(不熟悉的) papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half-written letter in the pile in which my husband had given his new telephone number to a friend.

    That family not only restored the important documents to us that day but also restored our faith and trust in people. We still remember their kindness and often send a warm wish their way.

    The kids in a village in Ethiopia 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 there are no schools or teachers. 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.

    Have you ever noticed how Americans fill up their entire glass with ice and then pour their beverage(饮品) in, but Europeans take their drinks at room temperature? In the U. S., we've created fridges that give you cold ice at the press of a button, but in Britain they typically serve their tap water warm.

    This tradition—if that's what you want to call it-dates back to the 19th century. During that time, it was already commonplace for most American homes to have an ice box. Ice would be harvested in northern America or Canada and shipped across the Atlantic and sold at a high price in British department stores. Can you imagine heading to Macy's to treat yourself to a block of ice?

    Putting ice in your drink started to become somewhat of a fashion(时尚) trend for the wealthy in Britain. Some would put a few cubes in their champagne and sip on their chilled drinks at high-class parties. But, like with any fashion trend, it eventually faded, mainly because the ice was just too expensive. And even once ice boxes began appearing in homes in Britain as well, Brits never took a liking to ice in their drinks.

    So, next time you travel overseas, don't feel offended(冒犯) when your server gives you an eye roll when you ask for ice water.

    I have never forgotten the firm belief I had in the arrival through the chimney (烟囱) of the little Santa Claus (圣诞老人), the kind, white-bearded old man who at midnight left in my tiny shoe a present I found the next morning.

    Midnight! It's the perfect hour children don't know. What great efforts I made not to go to sleep before the little old man appeared!

    I had both a great desire and great fear of seeing him, but could never stay awake until then, and the next day my first look was for my shoe. He never failed to carefully wrap (包装) every present for me. I would run barefoot to get my treasure. It never was a very expensive present, for we were not rich. It was a cookie, an orange, or very simply a fine red apple. But it felt so precious that I barely dared to eat it. What a great role imagination plays in a child's life!

    I do not at all agree with the idea that the lies about Santa Claus should be stopped. Doubts and truth come all too soon on their own. I very well remember the first year, when I was five or six, I doubted that it was not Santa Claus who put the cookie in my shoe. Since then, it has never tasted as good as the first few years of my life.

    I noted that my son believed in him longer; boys are more naïve (天真的) than little girls. Like me, he made great efforts to stay awake until midnight. Like me, he loved the cookie baked in Heaven's kitchens. And like me, the first year of his doubts was the last year of the visit of the good old man.

    Once an old man rose early to read each morning. His grandson wanted to be just like his grandfather, so tried to emulate him every way he could.

    One day the grandson asked, “Grandpa, I try to read just like you do, but I don't understand most of it, and I forget whatever I do understand immediately I close the book. So what good is it for me to read?”

    The grandfather, who was putting coal on the fire, said, “Take this coal basket down to the river and bring me back a basket of water.”

    The boy did as told to, but the water leaked out before he could get the basket home.

    The grandfather laughed, saying, “You'll have to move a little faster.” This time he ran faster, but again the basket emptied. Out of breath, he decided it was impossible to carry water in a basket, and he went to get a bucket（桶）. But the grandfather said, “I want a basket of water instead of a bucket of water. You're just not trying hard enough.”

    The boy knew what he was trying to accomplish was impossible. However, he decided to show his grandfather a third time.

    The boy dipped the basket into the river and ran as hard as he could. With the empty basket, he gasped（喘气说）, “See Grandpa? It's useless!”

    “So you think it useless?” the old man asked. “Then look at the basket.” To his surprise, the boy found it washed clean of the dirty coal stains and now clean inside and out.

    “My child, that's what happens when you read the book. You might not understand or remember everything, but the words will change you inside and out. That is the work of reading in our lives.”

    Vinegar is great. It makes salad, fries and dumplings taste better, and you can even clean your windows with it. And now, according to scientists, it may even help the planet's population to ease hunger.

    Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) in Japan found that growing plants in vinegar makes them more resistant to droughts.

    This could mean that in the future, worries about climate change affecting the world's supply of food will be much lower.

    The discovery was made after the researchers studied the Arabidopsis, a plant known for its ability to survive in dry weather. It was found that when the plant was placed in drought-like conditions, it produced a chemical called acetate(醋酸盐) – the main component of vinegar.

    After discovering this, the scientists experimented further by adding acetate to the soil of other plants, before they stopped giving them water completely. After leaving the plants for 14 days, they found that the ones treated with acetate had survived, while the untreated plants had dried up and died. It's hoped that this simple method of survival could soon be used to help farmers in dry countries keep their crops alive.

    Jong Myong Kim, co-author of the study, told Popular Science magazine that he's already been in touch with people all over the world who are interested in trying this simple and cost-effective method out for themselves from flower growing companies to amateur gardeners.

    Although at this point keeping thirsty plants alive isn't as easy as just pouring vinegar over them, Kim said he and his team are working on making the process as simple as possible. "Now we are trying to cooperate with some farmers, and also some companies, to make a method to apply this system." he said.

    And for those of us who always forget to ask our neighbors to water our plants when we go away, hopefully this means the end of returning home from a trip to find our favorite flowers have died.
