As global temperatures continue to rise, more “extreme rain” events—intense, cats-and-dogs down pours—can be expected, said the study, published Monday in the journal Nature Climate Change. And that, scientists said, means an increased flood risk, particularly for the world's driest areas. The study challenges the idea that global warming is causing dry areas to become drier and wet areas wetter.

    “In both wet and dry regions, we see these great increases in heavy precipitation（冰雹）,” lead author Markus Donat, a climate scientist at the University of New South Wales, told Nature.

    Donat and his team collected data from 1951 to 2010 on extreme precipitation events from 11, 000 weather stations around the world, Nature reported.

     In that time, the number of days with“extreme precipitation” increased 1 percent to 2 percent per decade.

  “We found a strong relationship between global warming and an increase in rainfall, particularly in areas outside of the tropics,” Donat said in a statement.

  “Importantly, this research suggests we will see these extreme rainfall events increases at regional levels in dry areas, not just as an average across the globe,” Donat added.

    Peter Stott, a senior climate scientistat Met Office, told Climate Central that the study's findings are important, because more violent rainfall and flooding will “challenge our capability toadapt to a rapidly changing climate.”

    As Nature reported, the researchaligns（结盟）with a 2015 study that found global warming has led to a sharp increase in record-breaking precipitation events. Donat told Nature that his study should come as a warning to world governments.

    Given that many people 's moods(情绪)are regulated by the chemical action of chocolate, it was probably only a matter of time before somebody made the chocolate shop similar to a drugstore of Chinese medicine. Looking like a setting from the film Charlie& the Chocolate Factory, Singapore's Chocolate Research Facility (CRF) has over 100 varieties of chocolates. Its founder is Chris Lee who grew up at his parents' comer store with one hand almost always in the jar of sweets.

    If the CRF seems to be a smart idea, that's because Lee is not merely a seasoned salesperson but also head of a marketing department that has business relations with big names such as Levi's and Sony. That idea surely results in the imagination at work when it comes to making different flavored (味道)chocolates.

    The CRF's produce is “green” made within the country and divided into10 lines, with the Alcohol Series being the most popular. The Exotic Series—with Sichuan pepper, red bean (豆), cheese and other flavors also—does well and is fun to taste. And for chocolate snobs, who think that they have a better knowledge of chocolate than others, the Connoisseur Series uses cocoa beans from Togo, Cuba, Venezuela , and Ghana, among others.

    I travel a lot, and I find out different "styles" of directions every time I ask "How can I get to the post office?"

    Foreign tourists are often confused in Japan because most streets there don't have names; in Japan, people use landmarks in their directions instead of street names. For example, the Japanese will say to travelers, "Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop."

    In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat; in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, "Go north two miles. Turn east, and then go another mile."

    People in Los Angeles, California, have no idea of distance on the map; they measure distance in time, not miles. "How far away is the post office?" you ask. "Oh," they answer, "it's about five minutes from here." You say, "Yes, but how many miles away is it?" They don't know.

    It's true that a person doesn't know the answer to your question sometimes. What happens in such a situation? A New Yorker might say, 'Sorry, I have no idea." But in Yucatan, Mexico, no one answers "I don't know." People in Yucatan believe that "I don't know" is impolite, they usually give an answer, often a wrong one. A tourist can get very, very lost in Yucatan!

    The holidays are the best time to ask the elders in your family for advice. For most people, the approaching holiday season includes more time with the extended family, including the elder generation.

    Unfortunately, older adults are often unseen in the popular media. Yet there's a big body of evidence that shows the benefits of older adults' wisdom and the value of developing communication across generations.

    First, over the course of human history, older people have played very important roles as advice-givers. Anthropological (人类学) research shows that survival in pre-literate societies was dependent on the knowledge of the oldest members.

    In recent times, most of the researches about intergenerational communication occur within formal programs, such as ones including older adults in public schools or having youth visit assisted living facilities. Also, you can apply many of the lessons of the researches to your own family gatherings.

    There is clear evidence that it is good for young people to spend time with older adults. The youth who participated in intergenerational programs showed more respect toward older adults, less anxiety, and higher self-esteem. Research also shows that interacting with younger people is good for older adults. A systematic review found that older adults who participated in intergenerational programs were likely to experience more satisfaction with their lives, higher self-esteem and fewer symptoms of depression. Interactions during intergenerational programs can be positive even when an older adult is experiencing memory or cognitive problems.

    Having children teach computer or video games to the older generations can be a fun way to spend time together. A study found that intergenerational games can help family members to bond. Another idea is to encourage the youth to ask older family members for their advice about life.

    The youth can ask older adults specific questions about the lessons they learned from their life experiences.

    The take-home message is that time with older relatives is one of the true gifts of the holiday season. Make the most of it by spending time with the older generation!

    Maggie had never experienced an earthquake before, only prepared for it. As long as she could remember, preparing for an earthquake was routine (常规的) at school. Her family as well had made plans in the event of a natural disaster. Earthquakes are so much more common on the West Coast of the United States.

    Today Maggie was home alone. Maggie knew her mom would be driving home on the busy freeway, thinking about preparing supper for Maggie's dad. Maggie's dad would arrive at the airport. He was coming home from a two-week business trip.

    Maggie arrived home from school at the regular time. She was taking some biscuits from the kitchen cupboard, when she felt it. First just a tremor (微震), then the violent shaking. Maggie quickly ran under the large, wooden table in the dining room. The sounds of breaking glass and the crashing (坠落声) of many things were frightening. But the table remained undamaged, and Maggie hid herself in fear.

    After what seemed like a century the earthquake appeared to be over. Maggie could hear the sound of water rushing below her in the basement. The smell of natural gas was present in the air. Maggie knew where the main water valve (阀门) was located. Dad had shown her where it was and how to turn it off. Slowly and carefully she came out from under the table. The once tidy home was now almost unrecognizable. As Maggie reached the open basement door she could see the steps were still in good condition. She carefully made her way down into the dark basement. While still on the steps she felt the water rising and rising. Suddenly Maggie felt a lot of pain as a large ceiling beam (天花板梁) hit her head and shoulder. She fell onto some storage boxes…

    All the housewives who went to the new supermarket had one great ambition: to be the lucky customer who did not have to pay for her shopping. For this was what the notice just inside the entrance promised. It said: "Remember, once a week, one of our customers gets free goods. This May Be Your Lucky Day!"

    For several weeks, Mrs Edwards hoped, like many of her friends, to be the lucky customer. Unlike her friends, she never gave up hoping. The cupboards in kitchen were full of things which she did not need. Her husband tried to advise her against buying things but failed. She dreamed of the day when the manager of the supermarket would approach her and say:" Madam, this is Your Lucky Day. Everything in your basket is free."

    One Friday morning, after she had finished her shopping and had taken it to her car, she found that she had forgotten to buy any tea. She dashed back to the supermarket, got the tea and went towards the cash-desk. As she did so, she saw the manager of the supermarket approach her. "Madam," he said, holding out his hand, "I want to congratulate you! You're our lucky customer and everything you have in your basket is free!"
