The first day of the month of May is known as May Day. It is the time of year when warmer weather begins. People celebrate the coming of summer with customs that are expressions of joy and hope after a long winter. Today, May Day activities have been moved to the May Day holiday on the first Monday of the month. It is a public holiday when families take advantage of the time off to visit some of the UK's many attractions, including parks, zoos, historic buildings, ancient towns and villages and beautiful countryside.

    May Day celebrations have their origins in the Roman festival of Flora, the goddess of fruit and flowers, which marked the beginning of summer. People would decorate their houses and villages with leaves and flowers they picked at daybreak in the belief that the vegetation spirits would bring good luck. In the very early morning, young girls went into the fields and washed their faces with dew (露水). They believed this made them very beautiful for the following year.

    May Day was an important day in the Middle Ages and was a favorite holiday of many English villages. People of the time used to cut down young trees and stick them in the ground in the village to mark the arrival of summer. This is the origin of the maypole (五月柱). People danced around them in celebration of the end of winter. Maypoles were once common all over England and were kept from one year to the next. The tallest maypole is said to have been put up in London on the Strand in 1661. It stood more than 143 feet high and was cut down in 1717, when it was used by Newton to support a new reflecting telescope (反射式望远镜) invented by Dutch scientist Huygens.

    Publishers of books for beginning readers are in the business of doing whatever they can to make children develop a love of reading. At times, that means they'll produce books that are more colorful and more packed with pictures. But it turns out that when it comes to learning to read books, more pictures aren't always better.

    In fact, simply having more than one picture on a page can negatively(消极地) affect the ability of preschoolers to learn words from that page, according to a new study by researchers at the University of Sussex. “Storybook reading is a great activity to help children increase their vocabularies,” writes co-author Zoe M. Flack in the University's School of Psychology blog.

    But the illustrations(插图) can affect how well children will learn new words. “For example,” Flack writes, “We know that children learn words better if illustrations are realistic.” Also, studies have shown that adding bells and whistles(哨声) to storybooks may negatively affect learning, according to Jessica S. Horst, Flack's co-author for the study. “We also know that children look within illustrations for the things they hear in the story, so if the story mentions a girl dropping an ice cream, children will look at the ice cream in the illustration.”

    With that in mind, Dr. Horst and Ms. Flack began to wonder what would happen when picture books show many illustrations on a page and how young children who haven't yet learned to read know which illustration to look at while listening to a story. To find out, they read storybooks that displayed either one or two illustrations per page to 36 three-year-old children. As it turns out, children who listened to stories with only one illustration at a time learned twice as many words as children who listened with two or more illustrations.

    Nowadays it's believed that the largest contributors to air pollution are gasoline vehicles. They not only give off harmful gases but also dangerous and heavy metal particles（微粒） that can result in environmental dangers. We can't stop using vehicles and thus stop air pollution right away. However, at least we can look for better replacements so that air pollution can be reduced. According to studies, hydrogen （氢）cars prove to be a better replacement for traditional cars.

    A hydrogen car is a vehicle that uses hydrogen as fuel for its engine to work. There are two types of hydrogen cars. The first one is to use hydrogen as a fuel, and the second one is to use hydrogen fuel cells（电池） to provide power for the car. Hydrogen and oxygen react chemically with each other to produce electricity, thus starting the car.

    There are many advantages of hydrogen cars. For example, hydrogen is available in plenty. Therefore, you needn't worry about a lack of hydrogen. More importantly, no harmful gases are released as by-products .The only by-products are water and a little amount of heat so air pollution is prevented up to a large extent.

    However, there are also some problems with hydrogen cars. For instance, in case of damage, the cost of repairing and replacing fuel cells is high. Worse still, hydrogen is a material which can burn easily, so it can result in a huge explosion of the car.

    The concept of hydrogen cars is relatively new for most people. Research is still in progress to reduce disadvantages and increase advantages. Therefore, hydrogen cars are expected to contribute their bit towards making this planet better and healthier!

    A five-year-old dog named Kelsey has been praised as a hero for helping to save the life of her owner who slipped in the snow and broke his neck.

    The man, Bob, was alone when he left his Michigan farmhouse on New Year's Eve to collect firewood. Expecting a journey of only several meters, Bob was wearing just long johns (衬裤), a shirt and slippers when he went outside, although the temperature was around -4℃.

    After the accident, he was unable to move in the snow. Fortunately, Kelsey came to his assistance.

    "I was shouting for help, but my nearest neighbor is about 400 meters away, and it was 10:30 pm, Bob explained." But my Kelsey came. By the next morning, my voice was gone and I couldn't yell for help, but Kelsey didn't stop barking."

    Kelsey's companion kept him warm by lying on top of him. She licked his face and hands to keep him awake." Kelsey kept barking but never left my side," Bob recalled. "She kept me warm. I knew I couldn't give up and that it was my choice to stay alive."

    Bob spent 20 hours in the freezing cold. When he finally lost consciousness, his dog kept barking. Finally, hearing the barking, Bob's neighbor discovered him at 6:30 pm on New Year's Day and called the emergency services at once. When Bob arrived in hospital, his body temperature was below 21℃. However, doctors were surprised to find that he didn't have any frostbite (冻疮). They believed it was because of Kelsey's determination to keep him warm, Dr. Chaim Colen, the doctor who treated Bob, said, "Animals can help and his dog really saved him... He was very fortunate.”

    Bob said he was "enormously" grateful to both Dr. Colen and his Kelsey, "They saved my life. They are truly heroes!"

    Traditional Chinese Medicine (TCM) needs to prove its worth through rigorous clinical trials, according to the head of one of China's largest herbal remedy companies, as a contentious new law to boost the $40bn sector comes into effect.

    Traditional Chinese Medicine is estimated by analysts to account for a third of sales in China's $117bn pharmaceutical (药学) market, the world's second largest. But most of those sales are of relatively cheap over-the-counter drugs, with many Chinese hospital doctors unwilling to prescribe TCM remedies because of the lack of evidence for their effectiveness.

    China's first law promising equal status for TCM and western medicine in the country's state-dominated healthcare system comes into effect this weekend. Provisions include encouragement for hospitals to set up TCM centres, and a licensing system for practitioners (从业者). "This law is very important for securing the status of TCM," said Wu Yiling, chairman of Yiling Pharmaceutical, a company that makes herbal remedies based on traditional recipes in the northern province of Hebei.

    Listed in Shenzhen, Wu Yiling has a market capitalization of RMB 20.7bn ($3bn). Mr Wu, the son of a herbal practitioner, controls a family fortune of $1.6bn, according to the Hurun Rich List.

    Mr Wu is both a supporter of the nature of Qi—the mystical energy force that provides the basis for much of TCM theory—and the clinical trials vital to western pharmaceutical companies. "TCM needs to develop using modern research methods," he said.

    For instance, researchers from Peking and Cardiff Universities tested the health benefits of Yiling's herbal medicine Yangzheng Xiaoji, publishing papers in the International Journal of Oncology that showed the drug can slow the growth of cancer tumours. "The theory and recipe is TCM, but in practice the evaluation of our medicines is carried out according to western evidence-based methods," Mr Wu said.

    Analysts say such tests can help gain support from doubtful hospital doctors and boost prescriptions. "Doctors need strong evidence that drugs definitely work," said Serena Shao, healthcare analyst at brokerage CLSA. "Some of these companies are currently doing clinical trials, and getting proof that their drugs have the same efficacy (功效) as chemical drugs. That's the way to go." she added.

    The TCM law has been greeted with doubt from China's western-schooled medical establishment, which points to a lack of rigorous training for TCM doctors, and a recent series of shocking events involving herbal injections believed to have been harmful. "Officials will try and encourage TCM, but also will be very cautious about what kinds of TCM they use in hospitals," added Ms Shao.
