Teachers' Day is, interestingly, not celebrated on the same day all over the world. In some countries it is marked by a holiday, in others it is a working day.

    International Teachers' Day is celebrated on October 5. Being held ever since 1994, it is in honor of teachers' organizations worldwide. Its aim is to encourage supports for teachers and to meet the needs of students.

    China    In 1939, Teachers' Day was set for August 27, Confucius' birthday. In1951, the celebration was stopped. However, it was founded again in 1985, and the day was changed to September 10.

    India     Teachers' Day is celebrated on September 5 in honour of Dr. Sarvepalli Radhakrishnan, the second president of India, whose birthday falls on that day.

    Russia    In Russia, Teachers' Day was celebrated on the first Sunday of October between 1965 and 1994. Since 1994, the day is observed on the October 5, just the same day as World Teachers Day.

    The US    In the US, Teachers' Day is non-official holiday. It is celebrated on the Tuesday of the first full week of May. A number of activities are organized in schools to honor teachers. The celebrations can continue for the whole week of May.

    Thailand     In Thailand, National Teachers' Day is celebrated every year on January 16. The first Teachers' Day was held in 1957. The day is a holiday in schools.

    Having experienced a shocking electrical accident, which caused him to become both blind and deaf, James Franco's world became completely dark and quiet for almost ten years. The loss of sight and hearing threw him into such sorrow that he tried a few times to put an end to his life. His family, especially his wife, did their best to tend and comfort him and finally he regained the will to live.

    One hot summer afternoon, he was taking a walk with a stick near his house when a thunderstorm started all at once. He stood under a large tree to avoid getting wet, but he was struck by lightning. Witnesses (目击者) thought he was dead but he woke up 20 minutes later, lying face down in muddy water. He was trembling badly, but when he opened his eyes, he could hardly believe what he saw: a tree and a muddy road. When Mrs. Franco came running up to him, shouting to their neighbors to call for help, he could see her and hear her voice for the first time in nearly ten years.

    The news of James regaining his sight and hearing quickly spread and many doctors came to examine him. Most of them said that he regained his sight and hearing from the shock he got from lightning. However, none of them could give a compelling answer as to why this should happen. The only reasonable explanation given by one doctor was that, since James lost his sight and hearing as a result of a sudden shock, perhaps, the only way for him to regain them was by another sudden shock.

    Windbreaks are barriers (屏障) formed by trees and other plants. Farmers plant these barriers around their fields, which help prevent the loss of soil, stop the wind from blowing soil away. They also keep the wind from damaging or destroying crops. Besides, extra trees and plants can be cut down and used or sold for wood.

    Windbreaks can be highly valuable for protecting grain crops. For example, in parts of West Africa grain harvests were as much as twenty percent higher in fields protected by windbreaks compared to fields without them.

    But here is something interesting about windbreaks. They seem to work best when they allow some wind to pass through the barrier of trees or plants around a field. If not, then the movement of air close to the ground will lift the soil. Then the soil will be blown away. For this reason, a windbreak works best if it contains only 60 to 80 percent of the trees and plants that would be needed to make a solid line. An easy rule to remember is that windbreaks can protect areas up to 10 times the height of the tallest trees in the windbreak.

    There should be at least two lines in each windbreak. One line should be large trees. The second line, right next to it, can be shorter trees or other plants with leaves. Locally grown trees and plants are considered the best choices for windbreaks. Trees reduce the damaging effects of wind and rain. Their roots help protect soil from being washed away. And trees can provide animals outdoors with shade from the sun.

Craziest Food Festivals sounds like a joke topic, but once you start looking into it, you'll realize they're everywhere—the crazier, the better.

    ⒈Bibimbap Festival

    In the South Korean town of Jeonjuloves, their “mixed rice” dish is a hearty serve of rice topped with raw beef, a rainbow of vegetables, a raw egg and gochujang sauce (韩国的辣椒酱) so much. They take four days out of October to celebrate it.

    Like any festival there's music, entertainment and magic, but making it that little bit different is the bibimbap that's whipped (搅拌) up in a big bowl by dozens of chefs and served to over 400 people.

    ⒉Waikiki Spam Jam (怀基基午餐肉节)

    Who knew this canned meat had so much love? Well, it turns out that a can of Spam is the go-to item in Hawaii, along with a grass skirt and garland (花环). The people of Hawaii love Spam so much that they even spend a day in May serving out the best Spam, a type of cheap canned meat made mainly from pork.

    ⒊Bessieres Easter Egg Festival

    At Easter time, for those in the French town of Bessieres it's all about an egg far less sweet.

    Here they celebrate the holiday by getting dozens of chefs to make one large omelette (煎蛋卷) - 15,000 eggs strong - for the townsfolk (市民).

    ⒋Potato Days Festival

    This festival actually takes place in Barnesville, Minnesota(明尼苏达州), the US. Over the last Friday and Saturday in August the town celebrates its potato-growing skills by hosting potato picking and peeling contests, as well as a Miss Tater Tot pageant (盛典) for five-and six-year-old girls.

    Author Avi, winner of a Newbery Award, a Scott O'Dell Historical Fiction Award, and several Boston Globe-Horn Book Awards, may have seen his first children's book published in 1970, but that doesn't mean he's lost his talent for connecting with young fans.

    The American writer, born in 1937, agrees that getting involved with his readers is one of the key reasons he keeps writing, and that he's been fortunate enough to hear directly from readers about the impact (影响) his books have had. “I have been touched many times by readers who find some special connection between their lives and something I have written: the Danish girl who read something of mine in Danish, and struggled to communicate that in her poor English; the autistic (自闭症的) boy who somehow found something meaningful about my books that reached his own inner life; the women who have told me how important The True Confessions of Charlotte Doyle was to them when growing up."

    Beyond his fans' questions about the characters he's created, the writer's most commonly heard question may be about his own use of the single name “Avi." “As a young adult, I was a reader of French literature, which has that one name tradition: Moliere, Racine, Anouilh, Gide, and so on," he explains. “Avi was given to me by my twin sister when we were very young children, and it stuck. Then my family discouraged me from taking up writing as a career because they considered my writing poor. By using Avi, I was showing my determination to them."

    Although he believes－and has the awards to show－that his writing skills have improved, writing still doesn't come easily to him, despite having over sixty books to his credit. “I never studied writing in any formal sense. I taught myself to write by reading, and by imitating what I was reading," he says.

    The writing task may be tough, but the payoff is big. “To create, share, and support the gift of reading and literature, is to give young people the gift of many worlds, within and without," Avi states.

    Each year there are at least five million people around the world who develop serious flu (流感), and almost half a million deaths. When someone we know gets the flu virus, we expect them to be very careful not to pass it on to others. Doctors and nurses working with flu patients also need to protect themselves from the virus. But what is the best way to do this? This is the question that flu expert Professor Jonathan

    Van-Tam at Nottingham University is trying to answer. He wants to find out how flu is transmitted, so that he can stop doctors and nurses getting sick.

    Van-Tam explains their method, "There are 41 volunteers in my experiment. Some healthy volunteers are made to get flu first. When they show symptoms (症状), other volunteers, usually called recipients(接受者), enter the house. Everyone lives together in the small space for four days. Some of the recipients wear face masks, and wash their hands every 15 minutes, but some have no protection. In this way we can study who catches the flu and which ways of transmitting flu are important. During the four days when they are in contact with the virus, and for the ten days after that, the flu recipients are checked regularly."

    The experiment is not simple and it is very expensive. It is difficult to design correctly, and it is also difficult to plan and carry out. Just one study like this takes about 18 months to organize and needs hundreds of people working on it. But Van-Tam believes it is worth because the results will help to decide what type of protection is needed for people working in hospitals with large numbers of flu patients around the world. And perhaps it could reduce the number of deaths from flu each year.
