Several times my daughter had telephoned to say, “Mum, you must come and see the daffodils(水仙花)before they are over.” I wanted to go, but it was a two-hour drive from Lake Arrowhead. "I will go next Tuesday," I promised, a little unwillingly, on her third call.

    The next Tuesday dawned cold and rainy. Still, I had promised, and so I drove there. When I finally walked into Carolyn's house and hugged and greeted my grandchildren, I said, "Forget the daffodils, Carolyn! The road is invisible (看不见的) in the cloud and fog, and there is nothing in the world except you and these children that I want to see!"

    My daughter smiled calmly and said, "We drive in this weather all the time, Mum. You will never forgive yourself if you miss this experience."

    After about twenty minutes, we turned onto a small road and I saw a small church. On the far side of the church, I saw a hand-lettered sign that read "Daffodil Garden."

    We got out of the car and each took a child's hand, and I followed Carolyn down the path. Then, we turned a corner of the path, and I looked up amazed. Before me lay the most beautiful sight. Flows of flowers of different colors seemed poured down the peak and slopes. There were five acres of flowers! A sea of daffodil! It was like a fairyland all beyond description.

    "But who has done this?" I asked Carolyn. "It's just one woman." Carolyn answered. "That's her home." Carolyn pointed to a well-kept A-frame house that looked small and modest in the midst of all that glory. We walked up to the house. On the patio (露台), we saw a poster." Answers to the Questions I Know You Are Asking" was the headline.

    The first answer was a simple one. "50,000 bulbs (鳞茎)" it read. The second answer was, "One at a time, by one woman." The third answer was, "Began in 1958."

    I thought of this woman whom I had never met, who, more than fifty years before, had begun one bulb at a time to bring the beauty and joy to the mountain top. Just planting one bulb at a time, year after year, had changed the world where she lived and created something of magnificence, beauty, and inspiration.

    When we multiply tiny pieces of time with small amounts of daily effort, we too can accomplish great things. Everyone can do something to change the world.

    Did you know that sixty percent of your body weight is water? However, a loss of only two percent of this water through dehydration (脱水) during exercise can significantly affect your performance. The more you sweat, the more your exercise performance declines, unless you drink enough to replace your loss of fluids (液体).

    When you lose too much water, you can overheat quite easily, especially in a warm environment. But this is not the only problem you may face. Dehydration leads to your heart pumping much faster, which means exercise becomes more difficult and requires more effort. Despite these problems, however, many of us simply do not take enough fluids in when we head for the gym or set out on a run.

    So why is this? How do we manage to lose so much water without simply drinking more to replace it? Well, it's easier than you think. When we are at rest, we quickly become aware that we are thirsty and will put that right by having a drink. When we exercise, on the other hand, our thirst mechanism (结构) does not work as effectively, so we don't notice early enough that we are actually thirsty. In fact, we only start to fed thirsty when we have already lost around two percent of our body weight.

    Another problem is that, the more dehydration we become during exercise, the more difficult it is to prevent further dehydration-because our stomachs become intolerant (不能容忍的) to fluids and we do not absorb water properly, just when we need it most.

    The key thing about fluids and exercise is to manage your intake properly-regular small amounts are preferable, and some should be drunk before the period of exercise begins. You also need to match your intake to the sort of exercise you are doing. For example, for one hour of exercise, such as taking part in a 10 km run, you need to drink about two extra litres of water. For longer periods of exercise, sports drinks are recommended.

    It is widely known that any English conversation begins with The Weather. Such a fixation with the weather finds expression in Dr. Johnson's famous comment that “When two English meet, their first talk is of weather.” Though Johnson's observation is as accurate now as it was over two hundred years ago, most commentators fail to come up with a convincing explanation for this English weather-speak.

    Bill Bryson, for example, concludes that, as the English weather is not at all exciting, the obsession with it can hardly be understood. He argues that “To an outsider, the most striking thing about the English weather is that there is not very much of it.” Simply, the reason is that the unusual and unpredictable weather is almost unknown in the British Isles.

    Jeremy Paxman, however, disagrees with Bryson, arguing that the English weather is by nature attractive. Bryson is wrong, he says, because the English preference for the weather has nothing to do with the natural phenomena. “The interest is less in the phenomena themselves, but in uncertainty.” According to him, the weather in England is very changeable and uncertain and it attracts the English as well as the outsider.

    Bryson and Paxman stand for common misconceptions about the weather-speak among the English. Both commentators, somehow, are missing the point. The English weather conversation is not really about the weather at all. English weather-speak is a system of signs, which is developed to help the speakers overcome the natural reserve and actually talk to each other. Everyone knows conversations starting with weather-speak are not requests for weather data. Rather, they are routine greetings, conversation starters or the blank “fillers”. In other words, English weather-speak is a means of social bonding.

    When your child lies to you, it hurts. As parents, it makes us angry and we take it personally. We feel like we can never trust our child again. Why does lying cause such anger, pain and worry for parents?

    Parents are understandably very afraid of their children getting hurt and getting into trouble, but they have very little protection against these things as they send their kids out into the word. Kids learn from other kids and from external media, and this makes parents feel unsafe because they can't control the information and ideas that their children are exposed to.

    When your kid lies, you start to see him as “sneaky（卑鄙的）”, especially if he continues to lie to you. You feel that he's going behind your back. You begin to think that your kids are “bad”. Because, certainly, if lying is bad, liars are bad. It's just that simple. Parents need to make their kids responsible for lying. But the mistake parents make is that they start to blame the kid for lying. It's considered immoral to lie. But when you look at your kid like he's a sneak, it's a slippery slope （滑坡谬误）that starts with “You lie” and ends up at “You're a bad person”.

    Kids know lying is forbidden. But they don't see it as hurtful. So a kid will say, “I know it's wrong that l eat a sugar snack when I'm not supposed to. But who does it hurt?” “I know it's wrong that I trade my dried fruit for a Twinkie. But it doesn't really hurt anybody. I can handle it. What's the big deal?” That's what the kid sees.

    So I think that parents have to assume that kids are going to tell them lies, because they're immature and they don't understand how hurtful these things are. They're all drawn to excitement, and they'll all have a tendency to distort（歪曲）the truth because they're kids.

    China's cancer researcher Zhu Chen, together with two French researchers Anne Dejean and Hugues de Thé, received Sjoberg Prize 2018 in Stockholm Concert Hall, Sweden on Friday.

    “We used wisdom from both Chinese and Western medicine and offered a cure to one of the most deadly cancers,” Chen told Xinhua, “I feel that Chinese medicine has potential to contribute more to human health. It struggles for benefiting all mankind. It's a language of peace, and of development and progress.” Chen recalled the cooperation with the two French researchers for over 30 years.

    This year's Sjoberg winners have developed a new and targeted treatment for a specific form of blood cancer called acute promyelocytic leukaemia (急性早幼粒白血病). It was once one of the deadliest forms of cancer, but it is now possible to cure nine out of ten patients who receive the new treatment. The winners have made this revolutionary development possible by methodically mapping the molecular mechanisms responsible for the disease.

    The Prize is awarded by the Royal Swedish Academy of Sciences and is funded (资助)by the Sjoberg Foundation. The foundation, with a donation of 2.5 billion US dollars, was founded in 2016, and serves to promote scientific research that focuses on cancer, health and the environment.

    The Prize is an annual international prize in cancer research awarded to individual researchers or research groups. The prize amounts to one million US dollars, of which 100,000US dollars is the prize sum and 900,000US dollars is funding for future research.

    In the future those who are taking care of old people may get help from the house itself.

    Over the last few years, new technology, such as the Internet, Wi-Fi and flat TV screens, has changed our homes and the way that we live. Now, another technology revolution is happening. A new project at the University of Hertfordshire wants to create a home that monitors people living in it who are elderly.

    The researchers have developed a wristband device（装置）which helps us to watch the elderly person who is wearing it. The device collects information to see if the person has fallen or has wandered away from where he or she should be.

    The assisted-living project is part of the university's wider Interhome project, which is the development of a smart house. The house remembers the habits of the person who lives there and it uses very low amounts of energy. The Interhome team hope that offering this service will help take care of the elderly. They say, "It's very important that these technologies are there to help and support and not replace any of the existing services."

    The Interhome is not just a research method. It's also a way for students from different scientific backgrounds to learn and develop technology. The university uses the latest technology to help students get experience by developing new hardware and software themselves. The team includes design, engineering and computer science students working together.

    "We are working on a smart-home project in Watford with some companies at the moment," says the project leader. "We are looking at how a smart home can provide even more services." This could help millions of old people around the world have a better and safer life in the future.
