One day, Mr. Smith went to a dinner party. He was wearing very old clothes. He came into the room.But people in the room didn't look at him. They didn't ask him to sit at the table. He wasn't happy. But he said nothing.Mr. Smith went home quickly and put on his best clothes. He went back to the party. Everyone in the room stood up and looked at him. They gave him good food to eat.Mr. Smith took off his coat, and put it on the food and said, "Eat, coat!" The other people were surprised and asked, "What are you doing? Why do you do that?" Mr. Smith answered, "I am asking my coat to eat food. When I wore old clothes, you didn't look at me. You didn't ask me to sit down. Now I am wearing these nice clothes. And you give me good food. Now I see, you give the food to my coat, not to me."

    As Simon Kindleysides, 34, took his first step in the London Marathon in April, he felt as if magic was in the air.

    "As we were walking toward the first mile, we actually started joining all the runners," he said. "Everyone was on the streets, cheering, and that was a magical moment." As time went on, the crowds and other racers spread around. Kindleysides and his team of eight supporters continued walking.

    Kindleysides, who is paralyzed(瘫痪的)from the waist down and typically uses a wheelchair, was equipped with an exoskeleton(体外骨骼)to help him walk. His supporters walked with him to change the batteries in his exoskeleton so he could keep moving.

    In 2013, Kindleysides was diagnosed with a brain tumor (肿瘤) that was growing in a way that pressed on certain nerves, leading to him losing feeling in his legs. He was told he would never walk again. Before his paralysis, the London-based singer and dancer had "always wanted to run a marathon," he said, but he never made the plan to do so--until this year.

    During the London Marathon, the last two miles were the hardest. "At that point, I was exhausted. It was freezing cold, and I was hurting emotionally," Kindleysides said. But he kept going. "I didn't want to let people down. I had a team of eight, and I was raising money for The Brain Tumour Charity," he said. "I didn't want to let them down, myself down, and I thought if I would get this far, I would have to continue."So he continued and made history as the first paralyzed man to complete the London Marathon on foot.

    Then, recovering at home, he shared his accomplishment with his three children. "They used to say I'm the only dad in their whole school who's in a wheelchair, and now they say I'm their dad, the only one who has walked a marathon," he said.

    Kindleysides is training to complete three more marathons next year, including the London Marathon again.

    Unlike most other holidays, the history of April Fools' Day, sometimes called All Fools' Day, is not totally clear. The only point in time that can be agreed on as the beginning of this tradition was 1582, in France. Before that year, the New Year was celebrated for eight days, beginning on March 25th. The celebration reached the highest point on April 1st. With the reform of the calendar under Charles IX，the Gregorian calendar(公历，阳历) was introduced, and New Year's Day was moved to January 1st.

    However, because in those days communications were not as developed as they are today, many people did not receive the news for several years. Some people refused to accept the new calendar and continued to celebrate the New Year on April 1st. These backward people were considered "fools" by other people. They  were often sent on "fools" errands(徒劳无益的工作)  or were made the targets of jokes.

    This developed, over time, into a tradition of playing a trick on someone on the first day of April. The tradition eventually spread to England and Scotland in the eighteenth century. It was later introduced to the American colonies of both the Britain and France. April Fools' Day thus developed into an international fun feast, so to speak, with different nationalities specializing in their own kind of humor at the expense of their friends and families.

Powerisers

    The ability to jump two meters in the air may not be something you have thought too much about. And most people have never considered running at 30 kilometers an hour. But just stop for a moment and think about how our new product could change your life.

    Your daily journey to your place of work is probably a mad dash for the bus. There is no point in taking your car because there are traffic jams, and anyway the car parks are probably very expensive or, worse still, full. Here is where Powerisers can help. It takes just a couple of minutes to put them on and then you are away, going past others or even jumping over the object which blocks your way.

    That is the practical use for our product, but then there is sport and exercise. Powerisers are set to be the next extreme sport and the deep-fit tools. You can imagine the 100 meters, the high jump or basketball performed by athletes wearing Powerisers. And what better way to build your muscles and keep fit?

    Our product is very simple. It is powered by a superlight spring, which uses the gravitational(重力的) pull from your body weight and pushes you with superhuman strength. There have been no records of serious injury related to the use of Powerisers, but extreme caution is recommended. We strongly advise the wearing of protective clothing, including at least a helmet(头盔).

    Powerisers make you feel as if you were walking on the moon. Now we make two different models: Basic and Professional. The Basic model is designed for the occasional users and costs around $ 500. The Professional model, which is designed for the competitive use, has a strongly-made structure and different springs, though that comes at the increased price of $800. Our Powerisers are guaranteed for two years and will be replaced without question if they fail during that period. That is how confident we are.

A kind of blue dye (颜料) called folium had been widely used to paint pictures on the pages of manuscripts (手稿) created in the Middle Ages. But long ago, this watercolor fell out of use.

"Manuscripts are an important part of the cultural works of art in the Middle Ages," said scientist Maria in an email to CNN. "Color is a basic feature of these manuscripts. To let ancient manuscripts. keep a good condition for future generations, we sometimes need to repaint their inside pictures through the ancient dye — like folium — that was once used in these manuscripts. But everyone who knew how to prepare folium had died long ago. So 'I led a team to study this dye."

Her team turned to books from the 1400s and found one that described the plant that was its source. It is a tiny plant with silvery-green leaves. Days later, the scientists reached a village in south Portugal, where nobody knew this little plant. However, after carefully going through a plenty of different plants growing there, the scientists finally raked out the plant they wanted and brought some back to their laboratory.

Back in the lab, the scientists produced the dye with the help of an ancient text on colors. The text has clearly described the ways to make it. "It's cool to have done that work of looking in the historical records and traveling back in time," says Casadio, who was not part of this study. It recreates an ancient process. By making the dye, the scientists could study its chemistry without experimenting on priceless delicate (易损的)  works of art, she points out.

Now, the researchers don't know the dye's stability(稳定性)and its ability against the environment that may wear and break it down over time. "To know such information is necessary if we desire to make these colors last long enough," Maria said. "So our study will continue."
