When was the last time someone unexpectedly did something nice for you? Not someone you knew, but a total stranger? It's happened to me a few times, but two instances really stand out.

    A few years ago, I was dining in a restaurant with a friend who kept talking about himself, completely not aware of the fact that I was sitting there in misery. It wasn't my friend's talks that made me suffer. I was recovering from a broken heart, and just sitting down to dinner reminded me of my last relationship. I could have burst into tears right there at the table.

    When we picked up the check, the waitress said, ―Your meal was already paid for.  My friend and I didn't have a clue how it happened. Then I remembered a man coming in out of the corner of my eye. He was dressed in mostly white, sat down at the bar, had a beer, and stayed for maybe ten minutes. The waitress said, ―Yes, the gentleman in white paid for you.  It felt like an angel was saying ―I see you, honey. It's going to be okay.

    Just last year, I was running a half-marathon. With just 1 mile to go, I was out of gas. Runners call it ―hitting the wall . I thought I couldn't move another inch. Out of nowhere, a stranger came up to me and said, ―What's your name, sweetie? Jennifer? Okay, Jennifer, let's go! Come on! It's just around the corner! You can do it!  And he ran with me until I picked up my pace. I found him at the finish line to thank him for the encouragement only to learn he wasn't even supposed to be in the race that day.

    I still shake my head when I think of these momentary angels that came to me at my point of need.

    Do you have any experiences like these?

    At the end of last summer my parents' house in Tunstall went up in flames. Several months on, we're still trying to find out exactly what happened, but my parents John and Carole were out when more than half the house was burned to the ground. What was left behind needed to be pulled down and most of the things that were not actually destroyed were so smoke-damaged that they would have to be thrown away.

My parents were both teachers and not the kind of people to fill their house with expensive furniture, so most of their belongings were memories—--including photos and the tracksuit(运动服) that Dad was given when he carried the Olympic torch (火炬). But what really upset me was not the loss of these things.

    Dad had an album(唱片) for every occasion. Once his car got broken into and he was more upset that his cassettes had been nicked(划伤) than about all the rest of the damage. So when I was considering doing something to help after the fire, I immediately thought about his music. We couldn't get the old photos back, but we could replace his CDs and records. Then I started a little page about my dad on the blogging site Tumblr.

    Within a few days, news of what had happened spread by word of mouth, and I was getting messages from friends I hadn't spoken to for years. I also heard from Dad's mates and even from people neither of us had ever met. Soon packages arrived from all over the country. I expected 100CDs if we were lucky, but his new collection would now run into the thousands!

    On Christmas Day, all the records, tapes and CDs were packed into a beautiful box, which of course, was for my dad. A lot of them came from his previous students and he was touched to realize what an effect he had had on their lives. Eventually , he told me, “What could have been a bad Christmas has been a very good one.”

    Nowadays, a new method is used to decide who are the top students in school. The best students are those who not only get high marks, but also follow the rules and the behavior standards for middle school students. Here are some of the new rules and standards.

    Tell the truth. Have you ever copied someone else's work in an exam? If you have, then don't do it again! That's not something an honest student should do. If you have played computer games for two hours in your room, don't tell your parents you were doing your homework.

    Learn to be loving and caring. Good students love animals and care about other people.

    Learn to work together with others. It would be more fun when more people work together. Did you quarrel(争吵) with your teammates when your basketball team lost? Only working together can make your team stronger. Be friendly to the people you are with. Try to think of others, instead of only yourself.

    Be open to new ideas. Have you ever thought that people could live on the moon? Perhaps you'll discover Earth II some day. Don't look down upon new ideas. Everyone's ideas are important. You should welcome them, because new ideas make life better for everyone.

    Use the Internet carefully. The Internet can be very useful for your study. Some websites on the Internet are not for kids, so make sure to visit the web pages that are good for you. You can use the web for fun or homework. Can't you find any good websites for children?

    Why is pink or purple a color for girls and blue or brown for boys?

    The answer depends largely on cultural values as well as personal experiences. To the Egyptians, green was a color that represented the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. In China, children are given money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect themselves against evils(灾祸).

    People's choice of colors is also influenced by their bodies' reactions toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally and physically. People who work in green environments have been found to have fewer stomachaches.

    Red can cause a person's blood pressure to rise and increase people's appetites(食欲). Many decorators will include different shades of red in the restaurant. Similarly, many commercial websites will have a red “Buy Now” button because red is a color that easily catches a person's eye.

    Blue is another calming color. Unlike red, blue can cause people to lose appetite. So if you want to eat less, some suggest that eating from blue plates can help.

    The next time you are deciding on what to wear or what color to decorate your room, think about the color carefully.

    Lovell Camps Kids' Club in Switzerland

    Lovell Camps Kids' Club is an English language Montessori（蒙台梭利）style club. Children will enjoy a wonderful and safe learning experience which includes language activities, cooking, arts and crafts, singing, dancing, etc.

    Learning outside the classroom plays a necessary role at Lovell Camps, making children experience the outdoors.

    There is an English saying that says, "Let Sleeping Dogs Lie." It means not bringing up an old problem. Researchers in Hungary have found another reason to let dogs keep on sleeping. It seems the animals are learning while they sleep.

    The Hungarian researchers placed tools on the dogs' heads to know about electrical activity in the brain. The brain activity, called sleep spindles(梭状波), takes place in human begins, and has been connected with learning. The researchers hope to understand how the dogs' ability to learn and remember changes as they get older. The study may help them understand how human brains change as we age.

    The researchers found differences between male and female dogs. Iotchey, a researcher, says the females appeared much better at learning new things. Female dogs have about twice as many spindles per minute as male dogs, they also happen to be the better learners, and they memorize the task much better. But it was harder for all the older dogs to remember things, especially when several things were happening at the same time.

    DoraSzabo also studies sleep spindles. Szabo is a neuroscientist in a university in Budapest. She says the older dogs have fewer spindles and are easily cheated. "If you first hide the reward into one bowl, then in another and in another, they get lost after a while. So their performance is going down, and they are getting poor in solving new problems."

    Researchers hope the study will not only help understanding of learning ability and memory changes in dogs, but also the aging of humans. Senior Researcher EnikoKubinyi adds that the aging dogs suffer from the same problems as humans who are aging. “Among very old dogs, up to two thirds of them show signs of dementia(痴呆), and this dementia is really very similar to that of humans, so we could use dog as a natural model of human aging."
