1 . What is a hero? We may think of the fictional characters with supernatural powers or great people who can influence world events. Now, as the nation continues its all-out efforts to fight against the novel coronavirus pneumonia(COVID-19), medical staff have become heroes in the eyes of the public.
As of Feb 19, a total of 32,000 medical staff outside Hubei province have been working to treat patients around the center of the outbreak.
Zhang Dingyu, the president of Wuhan Jinyintan Hospital, is one of these heroes. Since the hospital received the first seven patients in December, Zhang has been so busy that he barely gets any sleep. Even suffering from amyotrophic lateral sclerosis (肌萎缩侧索硬化), the 56-year-old doctor is doing his best to quicken his pace to save precious time for infected patients. “I have to run, racing against time to save more patients from the deadly disease, because I don’t have much time left in my life,” Zhang told Xinhua News Agency.
With the duty of saving lives, many medical professionals like Zhang have been working long hours for days, despite their fear and worries.
Lu Jingjing from Wuhan Children’s Hospital also works at a temporary mobile hospital. She does not let her parents know that she is now working with novel coronavirus-infected patients.
When her parents ask for a video chat, Lu says she is working and lets her husband and children chat with them instead.
“It’s dangerous but we should win the battle with the virus as soon as possible, so that medical staff and patients can go back home,” she told China Daily.
US writer Khalil Gibran (1883-1931) once wrote, “Tenderness and kindness are not signs of weakness and despair, but the manifestations of strength and resolution.” It’s true for the medical workers.
Everyone has fear, especially when it comes to deadly diseases. But for medical staff, saving lives comes first and is enough for them to be brave and stay on the front. They may look like ordinary people in daily life, but in these extraordinary times, they are heroes.

2 . History tells us that footwear was one of the first things ancient people learned to make. Footwear helped them across rocky paths or hot sands without injuring themselves. The earliest footwear we know of was simply a piece of plaited (编织的) grass or leather tied to the feet.
The ancient Egyptians seem to have invented the first footwear with a firm sole (鞋底) — sandals. Egyptian royalty usually wore sandals that had a different style from those with lower status (身份), while slaves were not allowed to wear anything on their feet. The sandal is still the basic form of footwear in many countries, particularly those with a hot climate, whereas in cold climates, an entirely different type of shoe appeared — the moccasin — a slipper-shaped shoe made of soft but strong leather.
The Greeks were the first to develop shoes with heels (鞋跟). Then, in the Middle Ages, shoes with long points at the toe became very chic for the nobility. These shoes were often very difficult to wear. Other trends followed, with square-toed shoes, wide shoes, and even shoes that could make a woman stand two feet taller. Not surprisingly, these sometimes led to accidents. Even today, fashion rather than comfort often leads to the kind of shoes women wear.
Mechanical shoemaking appeared in the 1800s in North America. Until then, shoes had been made with the same kinds of hand tools used by the ancient Egyptians. And in 1858, a machine was invented that could stitch (缝合) the sole of a shoe to the upper part. Now it was possible to make shoes that were shaped to fit either the left or right foot. Toward the end of the 1800s came a new type of shoe that was specifically designed for sports — the sneaker — and it soon become an all-time favorite.

3 . Pangolins (穿山甲) are the most trafficked (非法交易) mammals in the world and are facing extinction. To draw attention to these scaly (有鳞片的), anteater-like animals, a new wildlife documentary, Eye of the Pangolin, is attempting a unique way to inspire action and conservation. Partnering with the non-profit organization Pangolin. Africa, the documentary was made available on YouTube in May 2019. The intention is to reach communities wherever the Internet is available, especially African communities, who live near the animal’s habitats.
Over two years, the documentary crew traveled to South Africa, Ghana, Central African Republic and Gabon in search of the four unique species of pangolin, which has never been achieved before. Filmmakers Bruce Young and Johan Vermeulen say that they went into the shoot knowing relatively little about pangolins, but grew to respect and appreciate the animals. Getting close to the creatures over two years was a crash course in these secretive creatures. Johan Vermeulen said, "One thing however that might seem unimportant is that they are actually quite fussy eaters. You would think they would eat any type of ant, but they all prefer a specific type ant."
Pangolins are hunted illegally across Africa for their scales, which are used for traditional medicine, and their meat. In April 2019, Singaporean customs officials conducted two separate seizures of 24 tons of pangolin scales, which equals to the death of 69,000 pangolins.
Though the documentary focuses less on the trafficking of pangolins, and more on the animals in their natural habitat, the aim of the documentary is to inspire viewers around the world to call for action to end trafficking and protecting these unique creatures.
Filmed on location in South Africa, Ghana, Central African Republic, and Gabon, this powerful documentary is the story of two men on a mission to get all four species of African pangolin on camera for the very first time.

4 . A study of 27,000 men showed those skipping (不吃) breakfast were at a greater risk of heart problems. The British Heart Foundation said breakfast helped people resist (抵制) sugary snacks before lunch.
The men, aged 45-82, were studied for 16 years. During that time there were more than 1,500 heart attacks or cases of deadly heart failure. However, people who skipped breakfast were 27% more likely to have heart problems than those who started the day with a meal. The researchers took into consideration other lifestyle risk factors (因素) such as smoking and exercise.
Researcher Dr Leah Cahill told the BBC: “The take-home message is to eat in the morning when you wake up, preferably within an hour. The results show that something is better than nothing, but it’s always better to have something healthy and balanced.”
She said the timing of the meal seemed to be key and waiting until lunch rather than “having breakfast” may be straining (损伤) the body over time. This could be increasing the risk of high blood pressure and fatness which could in turn damage the heart. “Don’t skip breakfast,” Dr Cahill suggested.
Victoria Taylor, an expert with the British Heart Foundation, said: “These researchers only looked at men aged over 45, so we would need to see further research to prove that breakfast has the same effect on the heart health of other groups of people. What we do know is that a healthy breakfast can make that mid-morning biscuit less tempting, as well as giving you another opportunity to widen the variety of foods in your diet. Cereals (谷类食品) with low fat milk are a good way to start the day. Try a banana or dried fruit on top and you’ll be on your way to a fine day before you’ve even left the house.”

5 . Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates（灵长类）to be cloned. Another one named Tetra was produced in the late 1990s by embryo（胚胎）splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus（原子核）with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transfer（SCNT）, can create more clones and allows researchers greater control over the edits they make to the DNA.
Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn’t been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers’ pouring water on the idea that the team’s results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.
But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.

6 . A new study has shown how computers and robots powered by artificial intelligence can read human eye movements to “read” human personalities.
The eyes, they say, are the windows to the soul. And if that is true, computers and robots powered by sophisticated(复杂的) artificial intelligence algorithms(算法) may soon have the ability to peer into your soul. That is the result of a new study on the connection between eye movements and personality, conducted by neuroscience researchers based at the University of South Australia and Published in the scientific Journal Frontiers in Neuroscience.
“Eye movements during an everyday task predict aspects of our personality,” wrote the researchers, led by University of South Australia neuroscientist Tobias Loetscher, whose team follows 42 study subjects around the university campus recording their eye movements, then determines their personality traits(特点) with “well-established questionnaires” for determining personality type, according to a summary of the study published by the site Science Daily.
The researchers fed the data into their AI algorithms and found that computers running the algorithms were able to record human eye movements and immediately determine a person’s major personality traits, such as “neuroticism, extraversion(外向), agreeableness, conscientiousness, as well as perceptual(感知的) curiosity”, the scientists wrote.
“The new findings could improve the way human beings interact with their computers and other high-tech devices, even robots, allowing for more natural and realistic social interactions with machines,” Loetscher said.
“People are always looking for improved, personalized services. Today’s robots and computers are not socially aware so they cannot adapt to non-verbal information,” Loetscher said in a statement quoted by Indian Express. “This research provides opportunities to develop robots and computers so that they can become more natural, and better at interpreting human social signals.”
The study revealed previously undiscovered relations between specific personality characteristics and specific eye movement tendencies, according to a summary in Britain’s Daily Mail newspaper.

7 . Macdonald paused a moment in front of the burning car. Flames six feet tall poured from the engine, the smell of melting rubber heavy in the air. For a few seconds, Macdonald thought about whether the car would explode, killing them both. He thought about how lucky he was to have already just survived a head-on collision between his truck and the red Chevy Cobalt now in flames. Was he ready to risk his life to save the man that he believed could have ended his?
The two-vehicle collision happened at 3:44 p.m. on Monday south of New market. Macdonald was heading to work when he says another car swerved into his lane, hitting him head-on. Soon after the collision, the other driver’s car burst into flames with him trapped inside. Macdonald, 25, came to a decision. He would try to save the man’s life. He ran to the car. The driver’s side door was blocked but the passenger’s door was pushed open by the driver, a 64-year-old man now barely conscious. Hardly noticing the heat, Macdonald opened the door and grabbed the shoulder of the driver’s jacket. He dragged the man about 15 feet before two bystanders came to help him pull the man to a safe distance. Moments later the entire car was on fire.
The police confirmed the other driver was charged with careless driving. Macdonald escaped the crash with whiplash, sore muscles and wrists from the airbag release, and a headache. The other driver received serious but non-life threatening injuries, said the police.
Macdonald is just grateful that both of them came out alive. “I’m just glad I stood up when I was needed,” said Macdonald. “You only get a couple of chances in your life to prove what you are made of.”

8 . Whenever something looks interesting or beautiful, there is a natural desire of us to capture (捕捉) and preserve it — which means, in this day and age, that we are likely to reach for our phones to take a picture.
Though this would seem to be an ideal solution, there are two big problems associated with taking pictures. Firstly, we are likely to be so busy taking pictures that we forget to look at the world whose beauty and interest encourage us to take a photograph in the first place. And secondly, because we feel the pictures are safely stored on our phones, we never get around to looking at them, so sure are we that we’ll get around to them one day.
The first person to notice the problems was the English art critic (评论家), John Ruskin. He was a keen traveler who realized that most tourists make a poor job of noticing or remembering the beautiful things they see. He argued that humans have a natural tendency to respond to beauty and desire to have it, but there are better and worse expressions of this desire. At worse, we get into buying souvenirs or taking photographs. But, in Ruskin’s eyes, there’s just one thing we should do — attempting to draw the interesting things we see, regardless of whether we happen to have any talent for doing so.
Ruskin said, “Drawing can teach us to see: to notice properly rather than gaze absent-mindedly. In the process of recreating with our own hand what lies before our eyes, we naturally move from a position of observing beauty in a loose way to one where we acquire a deep understanding of its parts.”
Ruskin deplored the blindness and hurry of modern tourists, especially those who prided themselves on travelling around the whole Europe in a week by train, “No changing of places at a hundred miles an hour will make us stronger, happier, or wiser. There was always more in the world than men could see, if they ever walked slowly; they will see it no better for going fast. The really precious things are thoughts and sights, not pace.”

9 . English nowadays is widely used in science, business, the media and popular culture. Every time we turn on the news to see what’s going on in East Asia, or Africa, or South America, or elsewhere, local people are being interviewed and telling us about it in English.
Indeed, if one looks at the facts about the amazing reach of the English language, he or she would be surprised. English is used in over 90 countries as an official or semi-official language. English is the working language of many international colleges as well as of most international research scientists. It is believed that over one billion people worldwide are learning English now.
One of the most remarkable sides of the spread of English around the world has been the extent (程度) to which Europeans are accepting it as their language. English is spreading from northern Europe to the south and is now firmly set up as a second language in countries such as Sweden, Norway, Netherlands and Denmark. If one visits any of them, it would seem that almost everyone there can communicate with ease in English.
Recently, a special survey of Europeans’ use of languages has just been published. The report said that English is the most widely known foreign language now, with 43% of Europeans saying they speak it and that Sweden now holds the most of English speakers, with over 89% of the population. What’s more, English is the language rated as the most useful language to know, with over 77% of Europeans who do not speak English as their first language considering it useful.
English has without doubt become the global language.

The turning point came in 2007, after Graham was arrested yet again for possession. Wendy got a call from the Montana Drugs Project, which works with local law enforcement（强制执行） to keep track of youth-related crimes so it can help families in trouble. Following a counselor’s advice, Wendy hired two men to come to her home in the middle of the night, tie Graham and take him to a treatment program in Thompson Falls, Montana. “I was high when they came and really angry with my mom,” he said, “But if she hadn’t done that, drugs would have killed me.” After six months of treatment, Graham, now 19, came back to Kalispell, where he’s grown close to Wendy once again. “I still have the desires every day and attend support meetings every night,” he said, “But life is worth living again. My mom thinks that’s a miracle. I guess she is right.”
