Like fine food, good writing is something we approach with pleasure and enjoy from the first taste to the last. And good writers, like good cooks, do not suddenly appear full-blown. Quite the opposite, just as the cook has to undergo a particular training, mastering the skills of his trade, the writer must sit at his desk and devote long hours to achieving a style in his writing, whatever its purpose is — schoolwork, matters of business, or purely social communication.
You may be sure that the more painstaking the effort, the more effective the writing, and the more rewarding.
There are still some faraway places in the world where you might find a public scribe to do your business or social writing for you, for money. There are a few managers who are lucky enough to have the service of that rare kind of secretary who can take care of all sorts of letter writing with no more than a quick note to work from. But for most of us, if there is any writing to be done, we have to do it ourselves.
We have to write school papers, business papers or home papers. We are constantly called on to put words to papers. It would be difficult to count the number of such words, messages, letters, and reports put into mails or delivered by hand, but the daily figures must be extremely large. What is more, everyone who writes expects, or at least hopes whatever he writes will be read, from first word to last, not just thrown into some “letters-to-be-read” files or into a wastepaper basket. This is the reason we bend our efforts toward learning and practicing the skills of interesting, effective writing.

【推荐2】In an ideal world, we usually get eight hours of sleep every night, and wake up with enough energy before work. But when we're struggling to balance the responsibilities of everyday life, cutting back on sleep seems to be the only solution. Many of us rely on coffee or energy drinks to get us through the day, instead of making sleep a priority. Sadly, as delicious as it can be, caffeine is not the solution. Being tired not only brings down our energy levels, but also makes us less productive and less motivated. There are concrete steps you can take right now to renew your energy.
Awareness comes first because you have to understand what's going on before you can do anything to change it. Most of us are too busy to notice how fatigue(疲劳) really affects our bodies and minds. What signs of trouble do you regularly display? The patterns of your signs of trouble can give you clues about the negative effects of your fatigue. In addition, it's wise to start thinking about whoever can feel the effects of your fatigue.
Reflecting on the choices you've made can provide clarity, which will help you figure out what needs to be changed. During this reflection, you will be able to understand more about yourself and why you do the things you do. You may decide to forgive yourself for the mistakes you've made. Thinking about the positive aspects of your life will make you feel refreshed and ready to move forward.
Conversing with others not only provides support, but also leads to new perspectives and feedback that can help with treatment and what you need to heal. To start with, have an open mind and an open heart. Limit complaining. Complaints may need to be aired in order to relieve pressure, but if they dominate(占上风), anger will win. Tell the truth. You do not need to tell people everything, but you do need to be honest. Listen carefully because it shows respect.
The fourth step is about renewal—getting rid of what is bringing you down and making a fresh start. It's helpful to break the process down. It is easier to make small adjustments than big ones. On occasion, the small steps alone can remove fatigue. For instance, you may not need to change your career but change emphasis. If you feel hopelessly dragged down by fatigue, selfcare may be the best prescription.

【推荐3】My six-year-old son, Stephen, was in front of the TV and smiled. His favorite show was about to begin---a Phoenix Suns basketball game.
“Ladies and gentlemen," the announcer’s voice was heard, “here is your starting lineup (首发阵容).” The arena (球场) darkened and the lights flashed when the players ran into the court to sing their team song. Stephen clapped and danced around. My wife Lorrie and I laughed. Stephen had been performing this for months. “One day I’m going to take you to a game, son,” I promised.
About a year later, the construction company where I worked finished a project for a Suns player. One afternoon my boss called me. “The player has two extra tickets for tonight’s game! Just pick them up at my office,” he said. I picked up the tickets, but felt a little disappointed when I looked at the clock. Even if I had had a helicopter, we would never have gone to the arena in time for the player introductions. Stephen would miss his favorite part! I grabbed my key, got Stephen in my car and hit the road. “Lord,” I prayed, “I’d love to see the joy on Stephen’s face. Help us make it on time.”
When I drove, it began to rain heavily. Suddenly, lightning flashed right near the arena! I turned on the radio to listen to the game. The announcer said there’d been a power failure at America West Arena. Everyone was fine, but there would be a delay until they got everything running. Finally, I parked the car and we walked in hurriedly to take our seats. I hoped that we hadn’t missed the introductions.
The very moment we entered the arena, the lights darkened. The music started. “Ladies and gentlemen, here’s your starting lineup!” Stephen’s eyes grew wide. There wasn’t enough space for him to dance around, but I could tell that his heart was leaping more than his body was able to. Thank heaven, he hadn’t missed a thing. And neither had I.

【推荐1】On November 18, 2020, state workers who were tracking sheep were flying over the Utah desert in a helicopter. They noticed an object that is called monolith later, and landed nearby to see what it was. It was a shiny, three-sided metal column about 3.7 meters tall and planted solidly in the middle of the desert.
Bret Hutchings, who flew the helicopter, said, “I have to admit, that’s been about the strangest thing that I’ve come across out there in all the years of flying.” The shape of the monolith and its strange appearance in the desert has reminded people of a black monolith in the science fiction movie 2001: A Space Odyssey. In that movie, the monolith was also unexplained, but it appeared to have been created by creatures from another world.
Some people say that the monolith appears to be similar to artwork created by some well-known artists. But one of the possible artists died in 2011. Two others have said that the work is not theirs.
Still, people working for the government believe that the monolith was most likely put there as an art project. But they note that it was quite a difficult task. The monolith is in a hard-to-reach spot somewhere in the 93,000 square kilometers of Utah land managed by the US Bureau of Land Management (BLM). Delivering the column that seems valuable to that location in the traditional way would have required moving very heavy materials. They must have thought of other ways.
One metal statue in the desert may not cause too many problems for the sheep, but what if lots of people decide to visit the site? That’s one reason the DLM hasn’t released where it is. The BLM is also afraid that the monolith might encourage other artists to plant other similar artworks in the desert. That’s something that the department doesn’t want to happen. Anyway, the government still hasn’t decided whether to remove the monolith or let it remain.
1. Why did the author mention the science fiction movie?| A．To explain the film was imaginary. |
| B．To show the monolith is strange. |
| C．To make the text more interesting. |

【推荐2】Before you make friends, you have to decide who you want to be your friends. Most people like to have friends who like to do the same kinds of things they do.
The quickest way to make a friend is to smile. When you smile, people think you are friendly and easy to talk to. It may not be easy at first to smile, but remember most people will stay away from a scared or angry looking face.
One easy way to start a conversation with someone is to say something nice about him. Think about how great you feel when someone says something nice to you. Doesn’t it make you want to keep talking to that person?
Ask your new friends questions about themselves. Who’s their favorite singer, where do they live, what do they do after school are all good questions to start a conversation. Make sure you have something to add to the conversation, too. When someone asks you a question, do have an answer for them. There’s nothing that will stop a conversation quicker than a shrug（耸肩）for an answer.
Kids who show an interest in other kids and who are kind and friendly make good friends. Remember, everyone wants to be around people who like to do similar things and people who are nice to them.

Government officials suggest that Chinese people will take to the air, roads and railways 3.62 billion times over a 40-day period around the nation's most important holiday this year as people push their way home for family gatherings or to satisfy their new-found passion for travel.
Getting tickets to all those would-be travelers is a discounting challenge that tries your patience annually. And the pressure for the railway system is always the greatest. Railways are the transport of choice for low-cost long-distance travel, and that's where the ticketing system regularly falls down.
Much of the criticism has focused on the railway's online purchasing system, which has been unable to keep pace with the huge demand and also failed to stop scalpers (票贩子) from easily getting many of the hard-to-find tickets.
Railway officials believed that online sales were the fairest way to get tickets for travelers, and told reporters that the public need to be patient. While by now the railway service is far from satisfying, efforts are being made to provide online identity checks that would reduce the ticket scalping problems, and the situation is expected to get better in a few years. Meanwhile, for those traveling by car, good news is that the country's extremely expensive highway tolls (通行费) will be removed for the period of the official holiday.
1. Which of the following words can replace the underlined word "discounting" in Paragraph 3?
| A．Pleasing. | B．Rewarding. |
| C．Promising. | D．Discouraging. |
| A．is convenient for travelers |

【推荐1】Tony Wang, who has been living in London since high school, says: “The weather is always the best topic to start a conversation with here, and complaining about wet shoes and a destroyed hairstyle can bring people closer.” “I spend most of my time thinking about two things: what to eat, except potato, and what to wear to handle another cold, windy, rainy day.”
As early as 1894, John Barbour had already noticed the trouble that came with changeable weather and also the need for waterproof clothing. So, he started by supplying oilskins to outdoor workers, such as fishermen and sailors. He soon opened his first store, named J. Barbour & Sons, in South Shields, a port on the River Tyne in the northeast of England. Now, 125 years later, Barbour is a family business that’s been passed down five generations.
The brand’s most iconic (标志性的) product, the jacket with a rugged weatherproof waxed cotton shell, corduroy collar, corrosion-proof brass buttons and pockets for storage and drainage eyelets, has been improved over the decades, but it is still manufactured by hand. The brand has now reached over 40 countries, including China. And it gathered three Royal Warrants as manufacturers of waterproof and protective clothing: 1974 from the Duke of Edinburgh; 1982 from the Queen and in 1987 from the Prince of Wales.
This year, the British brand Barbour marks its 125th anniversary. And besides improving the classic and professional jackets, Barbour has also been attracting more consumers with the artsy sense. For this, it has been collaborating with other brands and artists, including Engineered Garments, a fashion brand from Japan; and Alexa Chung, a British model and BBC presenter, who owns a namesake fashion brand. Most recently, Barbour made the paintings of Hayden Kays, a London-based artist, wearable.
At the end of June, Kays was invited to celebrate the launch of the collaboration at Galeries Lafayette Shopping Mall in Shanghai. Kays brought two paintings this time, presenting the importance of love. One is named Look Into My Love, a colorful circle like a bull’s-eye. “This work is hypnotic, because I think love can make me go crazy. Love is great, and everyone loves love,” he says.
“Barbour is an amazing partner, and the brand has got such a strong British identity and heritage, and at the same time, connects British brands and artists to Chinese consumers through collaboration, excited to see people wearing my artworks thousands of miles away from home,” Kays says. Lyu Yi, the general sales manager of China Outfitters Holdings Limited Company, who’s managing the development of Barbour in China, says: “Barbour is maintaining its British genes by combining its sense of fashion and art, to add extra artistic value to clothing.”

【推荐2】As a major travel destination, London has its fair share of hotels. Unfortunately, many are overpriced, dull or a combination of both. To enjoy London like a Londoner, consider a vacation in one of these trendy neighborhoods.
Oxford Street
Boasting more than 300 high-end shops, Oxford Street is one of the busiest shopping districts in all of Europe. This active street also has a highly dramatic history. In modern times, it has developed into a street where British chain stores hold their celebrity（名人）launches. This includes the century-old Selfridges, the second largest department store in the United Kingdom.
Jermyn Street
Mention Jermyn Street in London, and the first words that come to mind are “gentlemen’s shirts”. In fact, the shirt makers at the famous Turnbull & Asser store have produced shirts for celebrated gentlemen such as Prince Charles and George W Bush. Jermyn Street takes its name from Henry Jermyn, who developed the neighborhood in 1667. Its residents of distinction include Sir Isaac Newton, Colonel Churchill Duke, and the Duchess of Richmond and Lennox.
Dean Street
An interesting history inspired tourists to visit and stay near Dean Street. In 1756 a young musician named Wolfgang Amadeus Mozart performed a concert at 21 Dean Street. Karl Marx lived in Dean Street from 1851 to 1856. His house sat above what is now the first-rate restaurant called Quo Vadis. Before he became an author, Charles Dickens was a regular on Dean Street. He participated in amateur productions at Fanny Kelly’s Royalty Theatre, located at 73—74 Dean Street.

【推荐3】Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses （球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.

【推荐1】Gregory Talley used to sleep in a park or under a bridge. The 50-year-old has been homeless for more than 10 years.
“It is hard. It’s hard to live homeless. You filled every day trying to find cut where you are going to get something to eat. If I hadn’t found wonderful Fairfax County Kennedy Shelter, I wouldn’t know where I would be by now. I might be dead,” Talley said.
The Kennedy Shelter is one of the facilities New Hope Housing provides for homeless people.
Pam Micheli has devoted her life to making the lives of this vulnerable（易受伤的）population better as executive director of the non-profit organization.
“I went to Africa in 1985. And I saw a huge amount of poverty, but I saw so much hope. And I decided that I should try to do something that would bring hope to people,” Michell said.
When Michell began working with New Hope Housing 25 years ago, its three shelters had about 80 beds. Now, it has 350 beds and serves about 1,500 homeless people every year. She has expanded the program beyond just providing beds for the night.
“We do outreach（拓展）, we do prevention, we do permanent housing. We do transitional housing. We have an education program with all sorts of different things to move people to end their homelessness,” she said, “Our Out of Poverty program is not just about money. It’s about you could be spiritually poor, you could be relationship poor ... you could be educationally poor. So it is focusing on how you get out of this poverty that has brought you to being homeless. The program tries to teach the shelter residents self-reliance（自立）and work values, and includes courses on planning and personal responsibility.
“I learned I still have opportunities to change it and I can change it,” said shelter resident Lewis Webster. “It is just about going forth in doing necessary work to do it. I mean if you really want better, you would do better and that’s the frame of mind of me now.”

“Hey!” She shouted. "I'm driving around giving free haircuts. If I go grab my chair, do you want one right now?”
The man looked to be in his 60s. He laughed, saying, "Actually, I have a wedding to go this week. I am really hoping to get a haircut. "
"I'll be right back," Steller said.
She drove off, went to the salon (美发厅) she owns, and moved a red chair into her car. en she drove back. The man, named Edward, took a seat. She started to give him a haircut. He told her about his growing up in Mississippi and moving to Minnesota to be closer to adult children. After the haircut was done, Edward looked in a mirror and said gladly, "I look good!”
To date, Steller has given 30 or so such haircuts to people around the city. It's more than haircut. Steller wants it to be a gateway to express care, value and appreciation, but also to know more people.

【推荐3】Jo Cameron, a 71-year-old Scottish woman, has never needed to take painkillers after seeing the dentist and can eat spicy chilies without any discomfort.
She thought little of it until she sought treatment for an ankle problem at the age of 65. Doctors were astonished to find that she experienced no pain despite severe worsening in her ankle. A year later, she said she felt no pain after experiencing what's typically a very painful operation on her hand for osteoarthritis(关节炎). She doesn’t take any medication and is fit and active, with no medical conditions apart from arthritis.
Her doctors decided to analyze whether her lack of pain sensitivity was due to genetics and found it was caused by a mutation(突变) in a previously unidentified gene. Researchers found Cameron had two obvious mutations in her genetic makeup, one in the FAAH gene and the other in what the scientists dubbed (复制) FAAH-OUT, which has been little studied by scientists.
In a case study published Thursday, researchers explained the discovery could help guide new treatments for a range of conditions, from post-operative pain to anxiety. The study said that Cameron's mother and daughter appeared to perceive pain normally. However, her late father had little need for painkillers, and her son reported having some degree of pain insensitivity, but not to the same extent as her.
“Now that we are uncovering how this newly identified gene works, we hope to make further progress on new treatment targets,” Cox said. “We need to learn from people who are suffering from pain but also those who are less sensitive to pain,” said Keogh, who is also the director at the university's center for pain research.
“The implications of these findings are of great value,” said Dr. Devjit Srivastava, who diagnosed Cameron. “One out of two patients after surgery today still experiences severe pain, despite all advances in painkiller medications,” he added. “The findings point towards a novel painkiller discovery that could potentially offer post-surgical pain relief and also accelerate wound healing. We hope this could help the 330 million patients who have surgery globally every year.”
