1 . Experts are warning about the risks of extremely picky(挑剔的)eating after a teenager living on a diet of chips and crisps developed lasting sight loss. Eye doctors in Bristol cared for the 17-year-old after his sight had gone to the point of blindness. Tests showed he had serious vitamin deficiency(缺乏). Dr. Denize Atan, who treated him at the hospital, said, “His diet was basically a portion of chips from the local fish and chip shop every day. He also used to snack on crisps and sometimes white bread and ham, and not really any fruit and vegetables.”
The teenager saw his doctor at the age of 14 because he had been feeling tired and unwell. At that time he suffered from vitamin B12 deficiency, but he did not stick with the treatment or improve his poor diet. Three years later, he was taken to the Bristol Eye Hospital because of progressive sight loss.
He was not overweight or underweight, but he had lost minerals from his bones, which was really quite shocking for a boy of his age. In terms of his sight loss, he met the standards of being blind. “He had blind spots right in the middle of his sight,” said Dr Denize Atan, “That means he can’t drive and would find it really arduous to read, watch TV or recognize faces.”
Dr Denize Atan said that parents should learn about the harm that can be caused by picky eating, and turn to experts for help. For those who are concerned , she advised, “It’s best not to be anxious about picky eating , and instead calmly introduce one or two new foods with every meal.” She said multivitamin tablets can supplement(补充) a diet, but cannot take the place of eating healthily. “It’s much better to take in vitamins through a varied and balanced diet,” she said, adding that too many certain vitamins , including vitamin A, can be harmful ,“so you don’t want to overdo it.”

Recently, your mother and I were searching for an answer on Google. Halfway through entering the question, Google returned a list of the most popular searches in the world. At the top of the list was “How to keep him interested.”
It surprised me a lot. I scanned several of the countless articles about how to be sexy and sexual, when to bring him a beer versus a sandwich, and the ways to make him feel smart and superior.
And I got angry.
Little One, it is not, has never been, and never will be your job to “keep him interested.”
Little One, your only task is to know deeply in your soul — in that unshakeable place that isn’t upset by rejection and loss - that you are worthy of interest.
If you can trust your worth in this way, you will be attractive in the most important sense of the world: you will attract a boy who is both capable of interest and who wants to spend his one life investing all of his interest in you.
Little One, I want to tell you about the boy who doesn’t need to be kept interested, because he knows you are interesting.
I don’t care if he can’t play a bit of golf with me — as long as he can play with the children you give him and revel in all the glorious and frustrating ways they are just like you. I don’t care if he doesn’t follow his wallet — as long as he follows his heart and it always leads him back to you. I don’t care if he is strong — as long as he gives you the space to exercise the strength that is in your heart. I couldn’t care less how he votes — as long as he wakes up every morning and daily elects you to a place of honor in your home and a place of respect in his heart. I don't care about the color of his skin. I don’t care if he was raised in this religion or that religion or no religion
Little One, if you come across a man like that and he and I have nothing else in common, we will have the most important thing in common: You.
Because in the end, Little One, the only thing you should have to do to “keep him interested” is to be you.
Your eternally interested guy,
Daddy

3 . Children born in the past four decades had the luxury of being the center of their parents’ attention. The entire family’s resources were poured into their education and well-being.
However，when the same resources are split between two children，the amount distributed to each one is going to shrink.
According to the Hangzhou Daily，when there are two children in the family，parents tend to choose public schools instead of private schools，which are usually more expensive. Each child is enrolled in fewer after-school training classes.
But having a second child may cure some deep-rooted problems in China’s traditional family education.
Having two children in the family can help to prevent one child being spoiled by too much attention，according to People’s Daily. It also spares the only child from the pressure of shouldering parental expectations all alone. Taking care of a sibling also enables children to gain a sense of responsibility，cooperation，obedience and caring.
China’s public education system is also expected to shift. Currently，there are not enough vacancies in kindergarten and schools to accommodate the potential increase in children.
“It’s not only the enrollment capacity of educational institutions that will feel the pressure. People are also placing more emphasis on the quality of education，”Peng Xizhe， director of the Population and Development Research Policy Center at Fudan University，told China Education Daily.
He predicts the government may have to invest more to support the educational system as a result of the new family planning measure.

4 . At first, the scientists wondered whether it was a mistake. Just 21 days after leaving the Norwegian island of Spitsbergen, an arctic fox had arrived in Greenland. And in less than three months, it made it to Canada.
The fox averaged nearly 30 miles a day- some days, though, it walked almost 100 miles. “When it started happening, we thought 'is this really true?” said Arnaud Tarroux, one of the researchers who tracked the female fox “Was there an deviation in the data?” The scientists found the data was real as the fox kept going. The creature's travels last year, recorded in a recent paper, surprised Tarroux and his fellow Norwegian researcher Eva Fuglei, even though the animal is known for its endurance and ability to survive in extreme polar areas.
Scientists already knew that some of the foxes, native to Arctic areas all around the Northern Hemisphere, made long journeys, but the fox these researchers followed stood out for just how fast it covered more than 2,700 miles. “We didn't really know how they would do that and how long it would take for an individual to do this kind of trip,” Tarroux said.
The coastal fox the researchers tracked, also known as a blue fox, landed in Ellesmere Island in Canada on 1 July 2018. Of the 50 or 60 animals the scientists put trackers on for a study, it was the only one that dared to go outside of Norway. The researchers found the fox set off because of a food shortage. The tracker stopped working in February, so researchers no longer know the fox's location, but it was last discovered on the same Canadian island in the area of Nunavut.

| A．The fox travelled exactly 2,700 miles. | B．50 or so foxes are outside Norway. |
| C．The fox landed in Canada last year. | D．The fox traveled because of food. |
5 . One day while trying to print all the class worksheets we needed for the day, I found myself shouting at my printer in front of my son. “Why won’t this stupid thing print?” I shouted. My son came up to me quietly, saying, “Calm down, Mommy. Maybe if you don’t shout at the printer, it will work. You need to have patience.”
He was right. I needed patience-patience with this whole situation. I stopped myself, realizing this was not the behavior I wanted my son to see. He was also right that I needed to calm down. Just like what I told him to do, I took a few deep breaths and walked away from the collapsed printer. Later that day when we were outside, I tried to keep the sense of calm I had slightly achieved. Once I blocked out all the anxiety over the virus, school, and my work-I found the afternoon peaceful and pleasant. I played flying disc with my son, simply enjoying each other’s company while the birds sang. It was an everyday moment I’ll never take for granted again.
From then on, things got a little easier. I started to give myself, and everyone else, some favour. I stopped holding myself to my perfectionism standards with every little thing because they were truly impossible to keep to.
With that favour, I changed my focus. Getting every school worksheet done correctly is not important. Neither is cleaning the house. And, apart from getting fired, neither is my work. Spending time with my family, and staying healthy emotionally and physically, became my main concerns. We took walks. We danced our hearts out during the Disney Family Sing-Along. We got up early and walked secretly into our backyard with telescopes to bird watch. Who knows, birding may be the new hobby we’re never giving up.

6 . Elizabeth Spelke, a cognitive (认知的) psychologist at Harvard, has spent her career testing the world's most complex learning system-the mind of a baby. Babies might seem like no match for artificial intelligence (AI). They are terrible at labeling images, hopeless at mining text, and awful at video games. Then again, babies can do things beyond the reach of any AI. By just a few months old, they’ve begun to grasp the foundations of language, such as grammar. They’ve started to understand how to adapt to unfamiliar situations.
Yet even experts like Spelke don’t understand precisely how babies — or adults, for that matter — learn. That gap points to a puzzle at the heart of modern artificial intelligence: We're not sure what to aim for.
Consider one of the most impressive examples of AI, Alpha Zero, a programme that plays board games with superhuman skill. After playing thousands of games against itself at a super speed, and learning from winning positions, Alpha Zero independently discovered several famous chess strategies and even invented new ones. It certainly seems like a machine eclipsing human cognitive abilities. But Alpha Zero needs to play millions more games than a person during practice to learn a game. Most importantly, it cannot take what it has learned from the game and apply it to another area.
To some AI experts, that calls for a new approach. In a November research paper, Francois Chollet, a well-known AI engineer, argued that it’s misguided to measure machine intelligence just according to its skills at specific tasks. “Humans don’t start out with skills; they start out with a broad ability to acquire new skills,” he says. “What a strong human chess player is demonstrating is not only the ability to play chess, but the potential to fulfill any task of a similar difficulty.” Chollet posed a set of problems, each of which requires an AI programme to arrange colored squares on a grid (格栅) based on just a few prior examples. It’s not hard for a person. But modern machine-learning programmes-trained on huge amounts of data — cannot learn from so few examples.
Josh Tenenbaum, a professor in MIT's Center for Brains, Minds & Machines, works closely with Spelke and uses insights from cognitive science as inspiration for his programmes. He says much of modern AI misses the bigger picture, comparing it to a cartoon about a two-dimensional world populated by simple geometrical (几何形的) people. AI programmes will need to learn in new ways — for example, by drawing causal inferences rather than simply finding patterns. “At some point — you know, if you’re intelligent — you realize maybe there's something else out there,” he says.
1. Compared to an advanced AI programme, a baby might be better at _______________.| A．labeling images | B．identifying locations |

7 . Michael is a guy who is always optimistic about life whatever happens.
One day I went up to Michael and asked him, “I don’t understand it. You can’t be positive all the time. How do you do it?”
Michael replied, “Each morning I wake up and say to myself, ‘Mike, you have two choices today. You can choose to be in a good mood or choose to be in a bad mood.’ I choose to be in a good mood. Each time something bad happens, I can choose to be a victim or choose to learn from it. I choose to learn from it. Life is all about choices. You choose how you react to situations. You choose how people will affect your mood. The bottom line is: It’s your choice how you live life.”
Soon, I left the big company that I had worked in for years to start my own business. We lost touch, but I often thought about him when I made a choice about life.
Several years later, I heard Michael had a serious accident, falling off 60 feet from a tower. After l8 hours of operation and weeks of intensive care, Michael was released from the hospital. I saw Michael about six months after the accident. When I asked him what had gone through his mind as the accident took place.
“The first thing that went through my mind was the well being of my soon-to-born daughter,” Michael replied. “Then, lying on the ground, I remembered I had two choices: I could choose to live or I could choose to die. I chose to live.”
“Weren’t you afraid?” I asked.
Michael smiled, “The doctors and nurses kept telling me I was going to be fine. But when they wheeled me into the operation room and I saw the expressions on their faces, I got really scared. In their eyes, l read ‘He’s a dead man.’ I knew I needed to take action.”
“What did you do?” I asked.
“Well, there was a nurse shouting questions at me,” said Michael. “She asked me if I was allergic(过敏) to anything. ‘Yes,’ I said. The doctors and nurses stopped working as they waited for my reply. I took a deep breath and yelled, ‘Gravity(重力)!’ Over their laughter, I told them, ‘I’m choosing to live. Operate on me as if I am alive, not dead’.”
Michael lived, thanks to the skill of his doctors, but also because of his amazing attitude.

8 . A new study shows that the increased heat from Arctic (北极的)rivers is making sea ice in the Arctic Ocean gradually disappear. The study published this week in Science Advance was led by the Japan Agency for Marine-Earth Science and Technology, together with other scientists in the United States, United Arab Emi rates , Finland and Canada.
According to the research, the main Arctic rivers bring more heat to the Arctic Ocean than they did in 1980. River heat is one of the reasons that cause sea ice loss of the Arctic Ocean. That loss is equal to about 120,000 square miles of 1-mcter thick ice. "If Alaska were covered by 1-meter thick icc. 20% of Alaska would be gone," explained Igor Polyakov, a re- searcher at the University of Alaska Fairbanks' International Arctic Research Center.
Rivers have the greatest influence during spring. The wanning water pours into the ice covered Arctic Ocean and spreads below the ice， slowly destroying it. Once the sea ice melts(融化), the warm water makes the temperature go up. The research found that much more river heat energy entered the air. Since air is mobile, this means river heat can influence areas of the Arctic far from river deltas (三角洲).
The influence was the most prominent in the Siberian Arctic, where several large rivers go into the Arctic Ocean. Canada's Mackenzie River is the only river large enough to contribute to sea ice meh near Alaska, but the state's smaller rivers are also a source of heat.
Polyakov says that rising global air temperatures will continue to warm Arctic rivers in the future. As rivers heat up, more warm water will flow into the Arctic Ocean, melting more sea ice,

9 . Recently whenever I turned on my computer or my mobile phone, news about the great effect of Hurricane Harvey（哈维飓风）on thousands of people caught my eye. I saw many unfortunate events. However, there was also lots of bright news that showed the goodness of mankind. As a reporter, I reported many human-interest stories when doing my job, That’s why the story about the guys in the bakery（面包店）caught my eye.
When the workers at a Mexican bakery chain in Houston were trapped inside the building for two days, they didn't sit there feeling sorry for themselves. They used their time wisely after flooding caused by Hurricane Harvey. While waiting for the eventual rescue that came on Monday morning, the four workers decided to make as many loaves of bread as possible for people around the neighborhood. They talked to their manager about their plan over the phone and the manager agreed.
The flood water rose in the street outside. They took advantage of their emergency power supply to bake bread. They used more than 4,200 pounds of flour（面粉）to create hundreds of loaves and sheets of sweet bread. Although the water kept rising, they continued baking to help more people. By the time the manager managed to get to them, they had made so much bread that they took the loaves to lots of emergency centers across the city for people affected by the floods.
The store manager, Brian Alvarado, told The Independent, “They've done more than they should have done. And what they had done has lit a light for people. I feel lucky to have them work in the bakery.”
Whenever a disaster occurs, nobody should feelforlorn. Instead, we should stay hopeful and take positive action to save ourselves and help others. Our acts of kindness will make a big difference to the people in the world as well as the world itself.

10 . Johnny Cash was born in 1932 in the southern state of Arkansas. His parents were poor cotton farmers. As a school boy, he began writing songs and he performed on radio programs. After high school, he joined the United States Air Force and served as a radio operator in Germany.
He returned to the United States in 1954 and formed a band with two friends and performed at local events. They began recording for Sun Records in Memphis. One of the songs Cash wrote became the first country music hit record for the company. It was “Cry, Cry, Cry.”
Johnny Cash performed all across the United States and Canada. By 1958, Johnny Cash was a successful recording artist, songwriter and singer. He was invited to perform at the Grand Ole Opry in Nashville, Tennessee.
Johnny Cash won many awards, including eleven Grammy Awards and the Kennedy Center Honors. He was elected to both the Country Music Hall of Fame and the Rock and Roll Hall of Fame. He also received a Grammy Lifetime Achievement Award.
He died on September 12, 2003, in Nashville at the age of seventy-one.
Fans say that Johnny Cash's music was important because it told simple stories about life and death. They say he cared about social issues and continued to express support for those who are poor and without political power. One of the last songs he recorded was one made popular by the rock and roll group Nine Inch Nails. It is called “Hurt.”
