A child who has once been pleased with a tale likes, as a rule, to have it retold in almost the same words, but this should not lead parents to treat printed fairy stories as formal texts. It is always much better to tell a story than read it out of a book, and, if a parent can produce what, in the actual situation of the time and the child, is an improvement on the printed text, so much the better.

    A charge made against fairy tales is that they harm the child by frightening him or making him sad thinking. To prove the latter, one would have to show in a controlled experiment that children who have read fairy stories were more often sorry for cruelty than those who had not. As to fears, there are, I think, some cases of children being dangerously terrified by some fairy story. Often, however, this arises from the child having heard the story once. Familiarity with the story by repetition turns the pain of fear into the pleasure of a fear faced and mastered.

    There are also people who object to fairy stories on the grounds that they are not objectively true, that giants, witches, two - headed dragons, magic carpets, etc. do not exist; and that, instead of being fond of the strange side in fairy tales, the child should be taught to learn the reality by studying hi story. I find such people, I must say so peculiar that I do not know how to argue with them. If their case were sound, the world should be full of mad men attempting to fly from New York to Philadelphia on a stick or covering a telephone with kisses in the belief that it was their beloved girlfriend.

    No fairy story ever declared to be a description of the real world and no clever child has ever believed that it was.

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple — eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

    The reason is thought to be so-called similarity attraction theory — where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

    In a test, participants were told to watch TV — where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble (咬), while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too.

    The researchers added, “Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions (交易) from the start.”

    Harley Street psychologist Dr. Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, “This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful.”

    Most people know that Marie Curie(居里夫人) was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.

    Born in September, 1887, Irene Curie was the first of the Curies' two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris. Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities（设备） to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium. Her services were recognized in the form of a Military's Medal by the French government.

    In 1918, Irene became her mother's assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.

    Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity（辐射能）. Irene Joliot-Curie died from leukemia on March 17, 1956.

    The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures (生物) from the earth. This idea may sound like something from a science fiction (科幻小说), but it is actually being taken seriously by many researchers.

    This suggested future for the "red planet" will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week. Leading researchers as well as science fiction writers will attend the event. It comes as NASA is preparing a multi billion dollar Mars research programme. "Turning Mars into a little earth has long been a topic in science fiction," said Dr Michael Meyer, NASA's senior scientist for astrobiology (太空生物学). "Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars."

    Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.

    But many experts are shocked by the idea. "We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet," said Paul Murdin, of the Institute of Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident they will find Martian life forms. Europe and America's robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.

    In addition, two different groups of scientists announced on March 28 that they had found signs of methane (甲烷) in the Martian atmosphere (大气). The gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planet's soil.

    But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project. "Before we have even discovered if there is life on Mars, we are talking about carrying out projects that would destroy all these native life forms, all the strange microbes that we hope to find buried in the soil," said Dr Pratt. This view is shared by Monica Grady, a planetary scientist at the Natural History Museum, London. "We cannot risk starting a global experiment that would wipe out the precious information we are looking for." she said, "This is just wrong."

    At first, Michael Surrell didn't see the black smoke or flames shooting from the windows of his neighbors' home. He and his wife had just parked around the corner from their own house in Allentown, Pennsylvania, when they got a call from one of his daughters, "The house next door is on fire!" He went to investigate. That's when he saw two women and a girl hysterical (歇斯底里的)on their porch.

    "The baby's in there!" one of the women cried. Though the fire department had been called, Surrell, then 64, instinctively ran inside. "The baby" was 8-year-old Tiara Roberts, the woman's granddaughter and a playmate of Surrell's three youngest kids, then 8, 10, and 12. The other two on the porch were Tiara's aunt and cousin.

Entering the burning house was like "running into a bucket of black paint," Surrell says. The thick smoke caused him to stumble blindly around, burned his eyes, and made it impossible to breathe. The conditions would have been hazardous for anyone, but for Surrell, who has chronic obstructive pulmonary disease (慢性阻塞性肺疾病), they were life-threatening. He was the last person who should have run into a burning building— he has lung disease. But that didn't stop him.

    After a few minutes in the smoke filled house, he retreated outside to catch his breath. "Where is Tiara?" he asked desperately." The second floor." her aunt shouted back.

    Surrell knew he couldn't hold his breath for long. So he uttered a little prayer, "Well, Lord, this is it. You gotta help me, because I'm not coming out without that little girl." Taking a deep breath, he went in a second time.

    The darkness was overwhelming. Yet because the house had a similar layout to his, he found the stairs and made it to the second floor. He turned to the right and was met by intense heat. He was already out of breath.

    "Baby girl, where are you?" His throat and lungs burned as if he'd inhaled fire instead of the smoke and soot in the air. Every blink stung his eyes. All he could hear was the crackling and popping of burning wood. ①.Still unable to see, Surrell fell to his knees on the hot wood floor. He crawled toward the sound, feeling around for any sign of the girl. An ominous thought crossed his mind: I'm probably gonna die up here.

    Finally he touched something. A shoe, then an ankle. He pulled Tiara toward him. ②Her body was limp and she wasn't breathing. He scooped her into his arms and stood. He felt the heat of the flames on his cheeks. Turning, he fought through the smoke and ran blindly into the blackness. The next thing he knew, he was at the front door, then outside. Surrell put Tiara down on the porch.

    ③. A voice told him, "You have to breathe for her." He started CPR -the first time he'd ever done so. The women stood behind him, praying silently. Soon a soot-filled cough came from Tiara's throat. Surrell gave five more breaths. She coughed again. Her eyes flickered. He gave one final breath. She opened her eyes and took a breath on her own.

    ④.Their eyes met. Surrell hugged her tight and said, "Uncle's got you.^" Soon after, his throat closed off.

    Surrell woke up in the hospital a couple of days later, having suffered severe burns to his windpipe and the upper portion of his lungs. He spent over a week in the hospital. Tiara was released from the hospital after a few days. The fire exacerbated Surrell's pulmonary condition, and he feels the effects even two years later. As a result, he takes extra medication that helps open his airways. "It's a small price to pay," he says. "I'd do it again in a heartbeat. Wouldn't give it a second thought."

A new study says that more than half the world's ocean area is "becoming greener," and the trend is connected to human-caused global warming.

It's not clear what is driving the greening. In some places, it could indicate changes in the amount of plankton or other organic material floating in the water. Plankton are a cornerstone of the ocean food chain, and these kinds of shifts could have ripple effects throughout the entire marine ecosystem.

The study, published on Wednesday in the journal Nature, examines 20 years of satellite data measuring light reflected at the surface of the water all across the globe, subtle changes that aren't necessarily visible to the naked eye. The research finds that 56 percent of the world's oceans are shifting in color — and on the whole, they're growing greener. The trend is especially strong in the lower latitudes, including the subtropics and tropics.

The researchers then used a computer model to find out whether climate change was playing a part. They conducted one set of simulations representing the oceans under a strong climate change scenario, and then compared them with a second set of simulations imagining a world in which climate change didn't exist. The model suggests that rising global temperatures are to blame.

The exact reasons still require some scientific digging. While climate change seems to be the culprit, the study also indicates that rising ocean temperatures in and of themselves aren't driving the greening.

There are plenty of other ways global warming is affecting the world's oceans, by changing the structure and flow of certain currents, for instance. These kinds of changes can affect the growth of phytoplankton and other factors that might be contributing to the greening.

The findings weren't a surprise to the researchers. They're consistent with the way researchers expect the global oceans to change as the world keeps on warming.

"I've been running simulations that have been telling me for years that these changes in ocean color are going to happen," study co-author Stephanie Dutkiewicz, a senior research scientist at the Massachusetts Institute of Technology, said in a statement. "To actually see it happening for real is no unexpected, but frightening."
