She carefully wrote notes about the star. The next night , it looked as if the” star” had 4It also seemed to have a tail (尾巴)！Now , Mitchell was sure that she had found a comet , not a star.

    I try to be a good father. Give my kids love. Work nights to pay for their schooling. But1with Michael Hoyt, I am nothing.

    This love2began in Winchester, 43 years ago, when Rick was strangled (勒住) by the umbilical cord (脐带) during birth, leaving him brain-damaged and unable to3his limbs (四肢).

    "He'll be a vegetable the4of his life," Doctors told Michael and his wife, Judy, when Rick was nine months old.

    But the Hoyts weren't5it. Because they noticed that Rick's

6followed them around the room. When Rick was 11 they took him to the engineering department and asked if there was anything to help the boy communicate. But doctors told the parents that there was7going on in their son's brain.

    "Tell him a joke," Michael said to the doctors. They did and Rick8. Actually a lot was going on in his brain.

    Equipped(装备) with a computer that allowed him to control the cursor (光标)9the side of his head, Rick was10able to communicate. What is his first word? "Run!" And after a high school classmate was paralyzed (瘫痪) in a(n)11and the school organized a charity run (慈善跑) for him, Rick typed, "Dad, I want to do that."

    Yeah, right. How was Michael, a man who never ran more than a mile12going to push his son five miles?13he tried. Surprisingly, that day changed Rick's life. "Dad," he typed, "when we were running, it felt like I wasn't14anymore!"

    And that sentence also changed Michael 's life. He wanted to give Rick that feeling as15as he could. Eighty-five times he's pushed his disabled son, Rick, 26.2 miles in marathons. Eight times in triathlon (铁人三项).

    "No question about it," Rick types. "My dad is the Strongest Dad in the World."

    Nearly 7,000 medical workers in the team supporting Central China's Hubei province left the capital, Wuhan, the hardest-hit city in the novel coronavirus outbreak in China, and went back to their hometowns on Tuesday, March 31, marking the largest scale departure (离开) of medics (医学工作者)since the first group left on March 17. The Civil Aviation Administration of China has organized 51 planes to support the departure.

    More than 42,000 medics from other parts of the country have joined the battle with local medics to fight against COVID-19. The support teams came from 21 provinces, cities and autonomous regions(自治区) and some of them worked on several battlefields during the past months. The support team from the First Hospital of China Medical University in Shenyang, was among those in the group. Sixty members were in charge of treating COVID-19 patients in 100 beds in the Union Hospital and treated 174 patients who have been seriously ill since they arrived on Feb 10.

    Wang Zhenning, the leader of its support team, expressed his thanks to the Wuhan people who offered great help to them. "I am proud towitness and play a role in history. We've been here, seen it happen and become better. Wuhan is our second hometown. We will forever care about the city and the people fighting with us." he said.

    Wuhan city government showed great thanks to all medics in a letter, expressing their gratefulness of the medics' efforts to save lives in the battle. "Thanks to your arrival, Wuhan welcomes today's peace and stability. We will always remember your kindness!" the letter said. In it, the city government also invited the medics to visit Wuhan in the future for sightseeing. Local people volunteered to line up and see medics off as the medics left for home after finishing their mission(使命) in Wuhan. Wuhan traffic police led the way for medics to the airport.

At thirteen, I was diagnosed (诊断)with a kind of attention problems. It made school difficult for me. When everyone else in the class was focusing on tasks, I could not.

In my first literature class, Mrs. Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hand right away and said, "Mrs. Smith, you see, the doctor said I have attention problems. I might not be able to do it. "

She glanced down at me through her glasses, "You are no different from your classmates, young man. "

I tried, but I didn't finish the reading when the bell rang. I had to take it home.

In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn't get much education. But Louis didn't give up. Instead, he invented a reading system of raised dots (点) ,which opened up a whole new world of knowledge to the blind.

Wasn't I the "blind" in my class, being made to learn like the "sighted" students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others; I just needed a quieter place. If Louis could find his way out of his problems, why should I ever give up?

I didn't expect anything when I handed in my paper to Mrs. Smith, so it was quite a surprise when it came back to me the next day--with an "A"on it. At the bottom of the paper were these words: "See what you can do when you keep trying?"

In the town of Calan Five, everyone had wings (翅膀). Flynn 1 being the best flyer in town. However, he had to wait for the day he turned nine years old because his wings would be big enough to fly that day. 

When the day 2 came, Flynn ran to the open field, moved his wings, and flew off the ground. But soon he noticed something strange. He was slowly going down until his feet hit the grass. 

Flynn 3 what was wrong. He was at the right age and should have had the4 to fly. But somehow, he failed. 

From that day on, Flynn felt a sense of 5 because he was the only one who couldn't fly apart from (除了) the little ones. He 6 to get out of his room. 

One day, his mom came in and told him a story. 

"When I was about your age, there was a kid who couldn't fly. He was like you, but he didn't 7 himself in his room. He knew that if he wanted to fly, he must keep trying. Years later, the boy8 to become the best flyer in our town. And he's your father. "

Flynn was 9 . He had no idea that his dad had experienced the same thing. The next day, Flynn went to the field and tried to fly again and again. He didn't know how long the 10 would take, but he would never give up. 

Ye Lianping is a 96-year-old retired teacher from a village in Anhui Province. He has been teaching left-behind children there for free during the past 24 years.

Teaching has always been an important part of Ye's life. After he retired, he began offering free English-language classes to left-behind children. He first set up a classroom in his own house. Later, with the help of the government, he got another two classrooms. To provide education for more children, he also set up the Ye Lianping Scholarship Fund with almost all his money and the donations (捐赠物) from others. So far, it has helped hundreds of left-behind children.

Ye is quite generous to these children, but he spends very little money on himself. He lives a very simple life. He lives with his wife in a house built over 30 years ago. He never buys any drinks. And he has been wearing the same jacket for over 40 years.

Although he is getting older, Ye is never tired of teaching. In 2018, he got hurt while riding a bicycle to buy vegetables. Instead of resting in bed for recovery, he quickly returned to class with a walking stick.

Ye is racing against time to spend as much time as possible on left-behind children's education. People call him "the candlelight of the village". But he said, "I'm just a firefly (萤火虫), making little light, not as much light as a candlelight can give."
