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.”

2 . My work started in 2003 at my local animal shelter’s Adoption Department. It seems like such a long time ago. In the 13 years that have passed, more than 50,000 animals have passed the doors of the shelter. Most of them, I do not remember. But occasionally there are animals who stand out. Tabby was one such animal.
Tabby was one of the many homeless dogs. What’s more, she was blind and deaf. Tabby’s chances at adoption seemed remote at best. But one day a woman named Loretta came to the shelter. Her son, Gary, who suffered from epilepsy (癫痫) had seen Tabby’s picture on the shelter’s website. They were interested in meeting her! Most boys would want a puppy, a dog who could grow with him and run through grassy fields on summer days. Tabby would never be able to do that. But as they say, "love is blind". After meeting her, they decided to adopt Tabby!
If Tabby’s story had simply ended with her successful adoption, it would still have been something very special indeed but it was what happened after her adoption that some might label as "magical" or perhaps even miraculous. As Gary and Tabby did everything together, they became so "in tune" with one another that Tabby began to telegraph Gary’s seizures (疾病发作) before they occurred, giving his family a warning that one was about to strike. What’s more, Gary seemed to be having fewer and fewer seizures since Tabby’s arrival.
How could it be? There are some things that happen in this world that challenge all logic and understanding. Sometimes, the best that we can do is to accept a miraculous thing, which we didn’t attempt to explain. Because when you try to explain it, you lose the beauty and wonder of it all.

| C．Love is Everywhere: a Poor Dog | D．Take Me Home: My Dear Boy |
3 . Technology is a double-edged sword(双刃剑)— while it brings convenience, it also brings new problems. The sword of “social media” even has its preference: It cuts deeper into girls than boys.
Jean Twenge, a professor at San Diego State University in the US, recently discovered an alarming trend: Since 2010, the number of teenage girls who suffer from major depression, showing signs like self-harm and suicide (自杀), has increased much faster than that of boys. It is social media again that is to blame.
Statistically, girls use social media more than boys. Boys tend to spend their screen time on games, where they talk to their teammates through headphones. Though not directly, this still counts as real human contact. Girls, however, simply type and browse through posts, which is a much more isolated (孤立的) experience. “They're not having a real-time conversation with someone most of the time,” Mary Fristad, psychologist at The Ohio State University, told NPR.
And when it comes to online shaming, girls are also more vulnerable than boys. “Girls face more pressure about their appearance, which could be exacerbated (加重) by social media,” wrote Twenge. Shannon McLaughlin, for example, is an 18-year-old from Blackburn College in the US. She shared with the Guardian how social media made her feel depressed.
But McLaughlin found a solution. She started volunteering with the National Citizen Service, where she made face-to-face contact with people. "It's so easy to forget the importance of real connections when we have hundreds of people that we' re trying to impress at our fingertips," she told the Guardian. And she hopes that others "look up from their phones and focus more on the world around them".

4 . Motion sickness is an uncomfortable feeling. The sickness it causes can strike people on an airplane, playing video games, or, commonly, when riding in a car. In a future where people may find themselves running around streets in self-driving vehicles, the problems could get worse.
We typically sense our physical position and movement in the world by relying on our eyes, the feeling we get in our body, and our inner ear. Motion sickness may develop when there's disagreement between what your eyes see and what your inner ear senses. If you're looking at your phone in a moving vehicle, your eyes see a stationary screen but your inner ear feels that you're moving. The result of that dissonance can cause sickness. The common-sense solution is to just stop looking at your phone, but some of the appeal of self-driving cars is that you could use the time to be productive or entertained by what's on a screen.
Researchers of a car-making company and a video game company have been studying ways to address these issues. And their solution uses an interesting medium: sound. The research had two goals: to explore if sound could help relieve motion sickness, and to help people trust self-driving cars more. They experimented with two different categories of sound: tips that tell passengers what's about to happen, and noises that alert passengers when the device has noticed something, like a pedestrian.
The most convincing experiment took place on a closed airport runway in Sweden, near Gothenburg, in August of last year. On that track, brave participants had to ride in the backseat of a car driven by a human and read from a tablet while the car navigated the course. With just 20 people, the study was small, but according to researchers, the presence of sound tips made people report that they felt less ill. Participants said the sounds helped prepare them physically, or adjust their bodies for what was about to happen.

5 . Traveling alone can be daunting. I have traveled by myself many times but, on every occasion, there was someone to meet me at the other end of the bus, train or plane journey. This time was different.
Last week I had a holiday, from work, but none of my friends had the same week off. I decided that I still wanted to do something, so I booked a train ride to Toronto and reserved a bed in a hostel for one week.
One week by myself. Would I be lonely? Would I be bored? Quite the opposite. In fact, there are many benefits that come from traveling alone. Firstly, I was able to do whatever I wanted. I spent hours in museums that would have seemed boring and dull to some of my friends. I walked all around the city, which' some people may have found too exhausting. Instead of relying on someone else to remember directions or to suggest activities to do, I discovered my' independence and developed map-reading skills that I didn’t know I had. I could get up and go to sleep when I wanted and I didn’t have to wait for anyone else to shower and get ready every morning. Being in the safe environment of a hostel with like-minded travelers also gives a great opportunity to meet new people from all over the world, which can help combat loneliness.
In spite of the benefits, I found that there were also some disadvantages of traveling alone. I missed having someone to talk to and to bounce ideas off. Experiences are often more enjoyable if they are shared, and part of the fun of traveling is the memories you have afterwards. Without a travel partner, I won’t be able to laugh about and remember my Toronto adventure with a friend or family member in years to come.
In addition, eating in a restaurant or cooking in the hostel was less fun on my own.
I am very proud of myself for traveling alone, and I had a fantastic time in Toronto. However, in the future, I think I will always prefer to travel with another person or in a small group. Though, maybe it depends on who you travel with I would rather be by myself than with someone who is lazy, difficult and argumentative.

6 . It would be easy to believe that Mother’s Day was created by a greeting card company. After all, the day is celebrated with special sales and brunches, lots of presents and massive advertising campaigns. But the day was actually conceived more than a century ago by Anna Jarvis of West Virginia as a way of honoring the sacrifices mothers made for their children.
Jarvis’s mother, Ann Reeves Jarvis, helped start “Mothers’ Day Work Clubs,” teaching women how to care for their children. During the Civil War, she organized “Mothers’ Friendship Day,” where mothers of Union and Confederate soldiers met to try to promote harmony. The younger Jarvis Was inspired by all the things her mother had accomplished with her social work.
When Jarvis was young, she overheard her mother praying, “I hope and pray that someone, sometime, will find a memorial mother’s day honoring her for the matchless service she offers to humanity in every field of life.” When her mom died in 1905, Jarvis looked through all the sympathy cards she received. She underlined all the kind words that praised her mother, reading them over and over. The outpouring of kindness for her mother inspired her to create a day to honor all mothers.
The white carnation was her mother’s favorite flower, so it became the symbol for the day. She said it symbolized the truth, purity and charity of a mother’s love. Her idea of celebrating Mother’s Day was wearing a carnation while visiting your mother or maybe going to church together. Children were also encouraged to write letters to their mothers, sharing the depths of their appreciation.
The first official Mother’s Day events were held on May 10. 1908, at the church where her mother taught Sunday School in Grafton, West Virginia, and at the Wanamaker’s department store auditorium（礼堂）in Philadelphia. Jarvis didn’t attend the event in Grafton, but she sent 500 white carnations.

7 . When you hear the word "birthmark", you probably think of one of those black or brown spots that you have on your body. For me, it's different -I have them on my lips and inside my mouth. I'm used to being asked, "What are those black marks on your lips?" When I tell people they're birthmarks, they usually say, "That's strange." I used to consider them ugly. However, my mom calls them beauty marks
In pictures, I used to hide my birthmarks by pursing（噘起）my lips so I wouldn't have to deal with people's questions. As I was growing up, people wore me out with them. Some people would ask me the same questions even before knowing my name. In society I feel like we judge people by their looks before their personality.
My birthmarks are caused by a genetic condition from my mom's side of the family. My mom's mom has birthmarks on her lips, and my mom's uncle and my uncle have some on their bodies. Every year I plan to have a procedure to remove them. But when imagining the process, I always get nervous and give up.
My cousin faces a similar challenge. She has a huge birthmark that takes up her whole arm. She's never tried to hide it or change her appearance. Once, her grandmother told her that the birthmark looked extremely prominent and suggested that she should wear long sleeves more often. If my cousin had actually taken that suggestion, she wouldn't be such a person as she is.
Inspired by my cousin, I am finally accepting who I am and now I don't hesitate when someone asks me about them either. I say, "They`re beauty marks" and smile without pursing my lips.

8 . Honeybees can’t swim, and when their wings are wet, they can’t fly, either. But Chris Roh and other researchers at the California Institute of Technology found that when bees drop into bodies of water, they can use their wings to produce little waves and slide toward land-like surfers who create and then ride their own waves.
As with many scientific advances-Isaac Newton’s apple or Benjamin Franklin’s lightning bolt-Dr. Roh’s experiment began with a walk. Passing Caltech’s Millikan Pond in 2016, he observed a bee on the water’s surface producing waves. He wondered how an insect known for flight could push itself through water.
Dr. Roh and his co-worker, Morteza Gharib, used butterfly nets to collect local Pasadena honeybees and observed their surf-like movements. The researchers used a wire to restrict each bee’s bodily movement, allowing close examination of their wings. They found that the bee bends its wings at a 30-degree angle, pulling up water and producing a forward force. Bees get trapped on the surface because water is roughly three times heavier than air. But that weight helps to push the bee forward when its wings move quickly up and down. It’s a tough exercise for the bees, which the researchers guess could handle about 10 minutes of the activity.
The researchers said the surf-like movement hasn’t been documented in other insects and most semiaquatic insects use their legs for propulsion, which is known as water-walking. It may have evolved in bees, they-predicted.
Dr. Roh and Dr. Gharib have imagined many practical applications for bees’ surfing. One plan is to use their observations to design robots able to travel across sky and sea. “This could be useful for search and rescues, or for getting samples of the surface of the ocean, if you can’t send a boat or helicopter,” Dr. Gharib said.

9 . I first began to wonder what was doing on a college campus when my parents drove off, leaving me alone in a parking lot, wanting nothing more than to find my way safely to my dorm room. The fact was that no matter how mature I liked to consider myself, I was feeling just a bit first-gradish. Adding to my distress was the impression that everyone on campus was watching me. My plan was to keep my ears open and my mouth shut and hope no one would notice I was a freshman.
With that thought in mind, I raised my head, squared my shoulders, and set out in the direction of my dorm, glancing at the campus map in my hand. And then I spent the afternoon seeking out each of my classrooms so that I could make perfectly timed entrance before each lecture without having to ask silly questions about its whereabouts.
The next morning, I found my first class and marched in. I chose a seat in the first row and to the side. I was in the front, but out of the professor's direct line of vision. Then I opened my anthology（选集）of American literature and looked at the date at the top of a page. "Welcome to Biology 101," the professor began. Cold sweat broke out on the back of my neck. I got out my schedule and checked the room number. I was in the right room. Just the wrong building!
So now what? Get up and leave in the middle of the lecture? Wouldn't the professor be angry? Wouldn't they all stare at me? Forget it, I settled into my chair.

| A．My college | B．A Mistake | C．Fresh Start | D．A Freshman |
10 . Nothing succeeds like success, as every parent of a straight-A student knows, but trying to stress academic excellence by telling your child, “You’re so smart!” may be counterproductive. Why? According to a 2017 study, children who think their intelligence is fixed are less likely to pay attention to and bounce back (重新振作) from mistakes than children who think intelligence can grow and change.
In the study, researchers looked at 123 children. The team assessed the children to determine whether they had a “growth mindset” (believing that you can work harder to get smarter), or a “fixed mindset” (believing that your intelligence is unable to change). They then asked the children to complete a fast-paced computer accuracy task while their brain activity was recorded. During the recording, researchers noted that brain activity stopped within a half-second after making a mistake, as children became aware of their mistake and paid closer attention to what went wrong. The larger the brain response was, the more the child focused on the mistake. Based on the data, they concluded that children with a “growth mindset” were much more likely to have a larger brain response after making a mistake. While children with a “fixed mindset” were able to "bounce back”, only if they gave their full attention to the mistake.
For parents, the lessons are clear: Don’t pay your children compliments that suggest that intelligence is fixed. If your child hands you an A⁺ score, don’t say, “You’re so smart!” Instead, say, “Wow, that studying really paid off!” or “You clearly mastered this material-way to go!” Note the effort, not the intelligence.
Besides, many parents shy away from addressing a child’s mistakes, telling them “It’s OK. You’ll get it the next time.” without offering them the chances to figure out what goes wrong. Instead, it’s better to reassure your children that mistakes happen, and work to figure out where and how they make the mistake.
