There was a doctor in our city who was famous for his skills. Once he received a little child who was badly ill. Thanks to his skill and care, his young patient got well and was soon able to get up and run about again.

    The child's mother was very much thankful to the doctor, and she visited him to thank him for what he had done for her child. “Doctor,” she said, “you have saved my little son. I don't know how to thank you enough. I feel that money alone cannot repay you, so I have made this little purse with my own hands, as a sign of my gratitude. I hope you will accept it.” The doctor stood up and said coldly, “Madam, a little present like that is very nice between friends, but a doctor needs to be paid properly for what he has done.” The lady was so surprised and hurt so much that she could not reply for a moment. Then she said quietly, “Perhaps you will tell me how much your fee is?”

    “Fifty pounds”, he answered.

    The lady opened the little purse and took out four fifty-pound bank notes. She handed one of them to the doctor, and put the other three back into the purse. She put the purse into her handbag and, saying good bye to the doctor, went out of the room.

    After a morning hike in the Saneum HealingForest, 46-year-old firefighter Kang Byoung-wook has tea made from the bark of an elm tree, practices yoga (瑜伽), and makes a picture with dried flowers. He is one of 40 firefighters taking part in a three-day program, the aim of which is to offer "forest healing" (森林治愈); the firefighters all have posttraumatic stress disorder (创伤后应激障碍).

    Saneum is one of three official healing forests in South Korea. Soon there will be 34 more. South Koreans-many of whom suffer from work stress, digital addiction, and great academic pressure have accepted the medicalization of nature with great enthusiasm.

    There is increasing evidence that being outside in a pleasant natural environment is good for us. But how many of us get to enjoy nature regularly? Fewer and fewer, it seems. According to Lisa Nisbet, a psychology professor at Canada s Trent University, evidence for the benefits of nature is pouring in at a time when we are most disconnected from it.

    "We don't think of being outdoors as a way to increase happiness," says Nisbet. "We think other things will, like shopping or TV." But South Korea is starting to challenge this opinion.

    So what are some of the benefits of nature that Nisbet refers to? Being surrounded by nature has one obvious effect: It calms us and reduces our stress levels. This has been shown to lower blood pressure and heart rates.

    Another experiment conducted by psychologist Stephen Kaplan found that people who took a 50-minute walk in a park had better attention and short-term memory than those who took a walk along a city street.

    Perhaps what's more surprising is that nature may also make us more creative. David Strayer, a psychologist at the University of Utah, showed as much with a group of participants, who performed 50 percent better on creative problem-solving tasks after three days of wilderness backpacking.

    In fact, we may never know exactly what nature does to the brain. Something mysterious will always remain, and maybe that's as it should be.

    Fantasy as a genre is often unfairly wronged. While there are plenty of authors who seem to be paid by the word and are only concerned with expanding volume, there are many authors producing fantastic works that are worthy of the word literature. While there were many worthy competitors, here are what we consider to be the great work of the greatest fantasy series of all time.

    ①The Dark Tower by Stephen King

    The Dark Tower actually shares some similarities with The Wheel of Time. In both series the first four books are the strongest, and you also get the sense with both Robert Jordan and Stephen King that they didn't quite know how to end their creation, which led to a very controversial ending in The Dark Tower's case along with some questionable decisions by King like his self-insertion in the story.

    King has created one of the most iconic fantasy characters of all time in the Gunslinger Roland and the world he creates, with all of its similarities to our reality, is a prosperous one. It's too bad that Stephen King doesn't dabble(涉猎) more in fantasy, because he clearly has a talent for world building. Not to mention everything he writes seems to be phone book sized, which would fit right in with the fantasy genre.

    ②Harry Potter by J.K. Rowling

    When considering a ranking of the greatest fantasy series of all time, the question of Harry Potter is a tricky one. There's inevitably opposition when something is as popular as Rowling's work, and add to that the fact that the series is seemingly meant for children and you have a case that naturally inspires a lot of debate. I'm not sure I believe Rowling did anything particularly new with Harry Potter, but a work doesn't necessarily have to be innovative for it to be great. Nearly every fantasy series owes a debt to Tolkien for instance, but that doesn't mean Tolkien has written the only work of fantasy that matters. Rowling didn't really come up with anything new, but the connection she made with tens of millions of readers is praiseworthy. People will be reading Harry Potter for decades to come, and I'm not sure a better introduction to fantasy could be found.

    "Dad," I say one day, "Let's take a trip. Why don't you fly and meet me?"

    As a manager from IBM, my father's job filled his day, his thought, his life. While he woke up and took a warm shower, I had fun under the Eiffel Tower. While he tied a tie and put on the same Swiss watch, I rowed a boat across Lake of the Ozarks.

    My father sees me travelling without a purpose, nothing to show for my 33 years but a passport full of funny stamps. He wants me to settle down (安定下来), but now I want him to explore the world.

    He agrees and we meet four weeks later in Rapid City.

    "What is our first stop?" asks my father.

    "What time is it?"

    "Still don't have a watch?"

    Less than an hour away is Mount Rushmore. As he looks up at sculptures of the four Presidents in granite(花岗岩), his mouth and eyes open slowly, like those of little boy.

    "Amazing," he says, "How was this done?"

    A film in the information center shows sculptor(雕塑家) Gutzon Borglum devoted 14 years to the sculptures.

    We look up and I ask myself, "Can I devote my life to anything?"

    No directions, no purpose. I always used to hear those words in my father's voice. Now I hear them in my own.

    The next day we're at Yellowstone National Park, where we have a picnic.

"Did you ever travel with your dad?" I ask.

    "Only once," he says. "I never spoke much with my father. We loved each other—but never said it. Whatever he could give me, he gave."

    The last sentence—it's probably the same thing I will say about my father. And what I want my child to say about me.

    In Glacier National Park, my father says, "I've never seen water so blue." I have, in several places of the world. I can keep traveling. I realize— and maybe a fixed job won't be as boring as I think.

    Weeks after our trip, I call my father. "The photos from the trip are wonderful," he says. "We have got to take another trip like that sometime." I tell him I've decided to settle down and find a fixed job, and I'm wearing a watch.

    Nasr Majid started hunting this fall at Blackwater National Wildlife Refuge (保护区)on the Eastern Shore of Maryland in USA, He's one of the relatively few new hunters who officials hope will help stop a nearly four-decade decline nationally in what has become a hobby for fewer than 5 percent of Americans.

    Natural resources and wildlife, officials in Maryland are encouraging hunting of deer, turkeys and some other wild animals, which is believed to be good for the environment. Without hunting, they say, sika deer will overpopulate the wildlife refuge and they'll overeat the bushes and other plants that provide important habitat for birds. On the western shore of the Chesapeake Bay, hunting is also important to prevent the spread of diseases such as Lyme.

    In many families, the hunting tradition has been handed down for generations^ But as longtime sportsmen age and children lose interest, the number of hunters in the United States fell by 2 million, from 2011 to 2018, to about 11 million.

    "Everything is changing. Kids are growing up in front of video games and computers instead of going hunting." said Chris Markin, a hunting specialist for the state natural resources department. "Adults usually focus on working and providing for their families. Those pressures are preventing many other potential hunters from going out, and from raising the next generation of hunters."

    To avoid such a decline, a new approach is needed. Government agencies and nonprofit groups are now launching mentoring (指导) programs to train more hunters, which not only helps preserve an industry and a culture but also means more protection for wildlife and their habitats through deer population control and investment.

    Luckily, there are those still eager to learn, like Majid. He was just looking for an outdoor hobby he could share with his children when he came across the mentors-hip program. Now, he feels capable of hunting on his own, but also has someone he can text with questions that pop up. His new pastime has already paid off for him—on his second hunt with his mentor, in the last minutes of daylight, he bagged his first deer.

On Monday, a scientist and doctor Robert Winston is to formally ask a question in congress about what assessments the government has made "for requiring adults riding bicycles in city centres to heave a licence and third-party insurance". The letter below is the entirely imagined response I would like the government to make to him.

Dear Robert,

You ask what assessments we've made for your proposal about obliging cyclists to have licences and insurance. The brief answer is: none. Nor do we have any plans to do so.

Why? Again, the short answer is this: it's a silly and pointless thing to suggest, as evidenced by the fact that practically no countries or territories anywhere in the world require cyclists to be licensed, or to have compulsory insurance.

I suppose it's only fair if I explain why I think it is such a non-issue. It's pretty simple: such a plan would achieve pretty much nothing, while causing significant problems. More widely, any sensible governments will do everything in their power to get more people cycling, not to put pointless obstacles in their way.

Let's just take one example. As I'm sure you know as a doctor, one of the problems facing our nation is that the National Health System is likely to collapse under the caring for an increasingly overweight population. Inactive living is central to this. Even a fairly brief daily bike trip can have miraculous benefits for people's health.

Next, how would such rules even work? Would the licensing and insurance be just for adults, or also children? How would the system even be enforced-would it also require all bikes to be registered with number plates?

Finally, what would you hope to achieve by this? If you believe licensing transport users stops wrongdoing, can I point to you the data showing how a third of drivers admit to using handheld phones while driving, despite the law forbidding it.

So, to summarize：your plan would be to introduce a hugely new administrative scheme that would most likely have limited effect on the behaviour of averagely law-abiding (守法的) transport users who rarely harm others, while putting people off from this beneficial type of transport.

I'm afraid I just don't get it.
