Today we talk about a time when half the world is waking from the dark, cold winter months. Spring! We often describe “spring” as a time of rebirth, renewal and awakening. Many trees are blossoming and early flowers are pushing through the earth. Things are coming to life!

    But the word “spring” is not just a season. It is also a verb that means something going on or coming out quickly. When you put “spring” and “life” together, you will get “spring to life”. This expression means something suddenly becomes very active or perhaps seems more alive! You may “spring to life” after hearing that a distant friend will be visiting you. Or maybe your favorite soccer team finally “sprang to life” in the second half, played well and won the match.

    Now, besides being a season and a verb the noun “spring” refers to a metal coil (线圈) that is wound tightly. When the coil unwinds, it often jumps. So, we often say a person “has a spring in his step” if he is lively and active. He might even appear to jump, or bounce a little when he walks.

    There is another way we use “spring” as a description. In the case of a “spring chicken”, “spring” means young. However, “spring chicken” is also an informal, humorous way to refer to someone who isn't young at all. So, we use this expression in the negative form, as in “no spring chicken”. For example, let's say you know an 85-year-old man who decides to run a marathon, even though he has never exercised before. You could say, “That's amazing! After all, he's no spring chicken.”

    But be careful when using this expression. It could be a little disrespectful. Let's say your boss shows you a picture of his wife, and you say, “Wow, she's no spring chicken.” That response would be disrespectful and a bad career move.

    Summer holidays are coming. Here are two posters for members of English Club in the  schoolyard：

    An analysis of almost 50 years of competitions—including Eurovision Song Contests and world skating championships—has found that contestants are more likely to win if they are among the last to appear before the judges.

    The study by an American university appears to provide scientific proof that the best man, or woman, does not always win. It found that, on average, the last competitor to appear in the Eurovision Song Contest was more than twice as likely to win as the one who went on first.

    The first rounds of figure—skating championships, for which the running order is selected at random, showed more dramatic results. The final skater had a 14 percent chance of victory, making him or her more than four times as likely to win as the first skater.

    The study showed a gradual worsening of chances for competitors who appeared earlier in the running order. A contestant who appears first in a contest is two percent less likely to win than one who appears second. A contestant who appears second is two percent less likely to win than one who appears third, and so on.

    The findings are published in the March issue of Acta Psychologica, a scientific journal. Robert Hardman, a senior lecturer in psychology at London Metropolitan University who specializes in the science of decision-making, said that the results were interesting. He suggested that the effect was caused by the limitations of the human memory.

    "When people make comparison, they aren't really able to make a lot of fine-grade discrimination. When contestants appear at the beginning of a contest, judges have little to compare them to and are perhaps cautious about the scores they give." he said.

    "Later on, when judges are able to compare the contestants to those that have gone before, they might give more extreme marks because they feel more confident about their judgments."

    On a Friday night, a poor young artist stood at the gate of the New York railway station, playing his violin. The music was so great that many people stopped to put some money into the hat of the young man.

    The next day, the young artist came to the same place, and put his hat on the ground gracefully. Different from the day before, he took out a large piece of paper and laid it under his hat. Then he began to play the violin. It sounded more pleasant than ever.

    Soon he was surrounded with people who were attracted by the words on that paper. It said, “Last night, a gentleman named George Sang put an important thing into my hat by mistake. Please come to claim(认领) it soon.”

    After about half an hour, a middle-aged man rushed through the crowd to the violinist and said, “Yes, it's you. I knew that you were an honest man and would certainly come here.” The young violinist asked calmly, “Are you Mr. George Sang?” The man nodded. The violinist asked, “Did you lose something?” “It's a lottery ticket(彩票),” said the man. The violinist took out a lottery ticket on which George Sang's name was seen. “Is it?” he asked. George nodded and took the lottery ticket and kissed it, then danced with the violinist.

    The violinist was a student at an arts college and had planned to attend advanced studies in Vienna. Later his classmate asked the violinist, “At that time you needed money to pay the tuition(学费) and you had to play the violin in the railway station every day to make money. Why didn't you keep the lottery ticket for yourself?” The violinist said, “Although I don't have much money, I live happily. But if I lose honesty I won't be happy forever.”

    Through our lives, we can gain a lot and lose so much. But being honest should always be with us.

    A recent university study found that current electric cars could be used for 87% of daily car journeys in the US. That figure could rise to 98% by 2020.

One hurdle to the widespread adoption of electric cars has been “range anxiety” —drivers' concerns about running out of petrol on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. In fact, charging points are becoming increasingly common throughout the USA.

    Attitudes towards electric vehicles have changed quite considerably over the last few years. Not that long ago, electric cars met with doubt, and their high price drove customers away. Thanks to improvements in battery capacity(电池容量), recharging times, performance and price, the current generation of electric cars is starting to persuade critics.

    As well as progress on the road, electric vehicles are taking to the sea and sky. Electric boats are among the oldest electric vehicles, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric planes are also being made, with Airbus and NASA among the organizations developing and testing battery-powered planes. The experiments could soon make electric flight a reality.

    Electric vehicles do not produce any emissions(排放物). Were the US to act on the study's findings and replace 87 percent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 per cent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim to be completely emission-free. Even so, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.

    The UNESCO has recognized the Chinese art of paper cutting on its Intangible Cultural Heritage List. But paper cutting is at the risk of disappearing.

    Voyo Woo, a Chinese immigrant, who loves paper cutting, worked hard to celebrate the ancient art form. With a keen interest in paper cutting, Ms Woo held a paper cutting exhibition at a shopping center near Washington. "I really love it. I get so much fun by doing it. So I'm just kind of hoping that more people will learn about this art which is about to disappear. I think it's time to take action. So I held it."

    Voyo Woo began to study paper cutting when she was a 14-year-old girl in southeastern China. Voyo Woo's teacher gave her extra training after class because Voyo Woo discovered a special love for it. Later, her beautiful paper cuttings won second prize in a national painting competition. "Paper is the easiest material that you can find. You can just turn it into beautiful art. I think it is like magic to me."

    Ms Woo came to the US after she finished college in 2008. She has been invited to show the art at a wide collection of events. She also has shown her skill and works at famous museums like the Smithsonian Institution's Freer and Sackler art galleries in Washington.

    "I saw so many people coming to me and asking me. They were amazed. I think it's important to introduce the art form to American people or anyone who is interested."

    Ms Woo placed examples of her art around her as she displayed paper cutting at the shopping center. Ann Russ, a shopper, was attracted by the nature of the work. She said it put her at ease. "I like to know about Chinese art, specifically because it's almost relaxing to put that much effort into it," Russ said.
