5 . A recent story on TikTok showed how two neighbors found companionship (陪伴) and a new spirit in life during COVID-19, thanks to a shared love of the piano.

The heartbreaking story started when Giorgio Lo Porto heard his neighbor playing the piano through their dividing wall. Lo Porto is an Italian living in London. He reached out to his neighbor and left a note, saying if he or she could play My Heart Will Go On. The mystery neighbor agreed, suggesting they play together. Over time the music between two complete strangers became a regular weekend engagement(约会).

A week later, the pair finally met and “it was better than expected,” shared Lo Porto. The mystery pianist happened to be a78-year-old Polish man named Emil. “He lost his wife in December due to COVID-19 and all he has been left is the piano. And he plays at 2 p.m. every weekend because his wife loved it,” shared Lo Porto.

While Emil didn’t want to appear on any of the videos, he did share his thankfulness to Lo Porto for keeping him motivated during a most emotional and lonely time.When the pair offered each other company, Emil also inspired Lo Porto to continue writing his own song. And Emil reported being happier after playing music with Lo Porto and was thankful to those who watched their performance.

The bittersweet story shows the unbelievable influence two complete strangers can have on each other. Emil moved out at the end of February. Lo Porto wrote, “Dear Emil, you changed my life. You gave me back my passion (激情)，and we shared that with the world. You’ll be in my heart. I’ll keep playing, thinking of how powerful music can be. You said I was your light, but you’ve been mine too. Bye, Emil.”

When I was in primary school, I disliked doing exercise. I felt tired when I did any kind of exercise. My parents were really     1     (worry) about my health. One day, after having supper, my father     2    (come) and asked me to have a walk with him in the park. I agreed and we went     3     together. It was hard for me to walk for half an hour. I wanted to give up,     4     my father encouraged me to keep on walking. From then on. I was often asked to walk with my parents. To my surprise, I could walk for an hour in the     5    (five) month. How     6    (pride) I felt! I loved taking exercise gradually. Now I am     7     excellent runner in my school. I take part in the school sports meeting every year.

During all our life, we may face a lot of     8    (difficulty). Don’t be afraid of     9    (they). Please try to face them     10    (brave). After you overcome what you used to be afraid of, you may find how great you are!

7 . Jacky Hunt-Broers ma, who lost one leg to cancer, is seeking to break a world record by completing 102 marathon runs. She set her goal in mid-January. And since then, she has been running the distance of a marathon. Most of the time, she averages just over five hours to complete a run. If she keeps successfully completing marathon runs every day, she will reach her goal by April 28.

Until five years ago, she was not very active. But then she looked into running and decided to give it a try. The sport ended up being quite costly. Currently, she runs on an artificial leg made of a strong, light material known as carbon fiber. The material, which is designed specially for running, costs about $10, 000.

But Jacky says her investment has been well worth it. The biggest struggle used to be that she had to admit part of her body was gone. “Running really changed my life,” she said. “It helped me accept myself as an amputee (截肢者). It gave me a sense of freedom. I fell in love with the process of pushing my body further just to see what I could do.”

However, she has faced both physical and mental difficulties during her record-breaking attempt. On one recent day, Jacky said she felt like giving up at 24 kilometers and began to cry. “I had a total emotional breakdown. I was like, ‘I just can’t do this.’” she said.

Jacky is documenting her progress online and has also gained a large social media following. As she nears the end of her goal, Jacky is hoping to inspire a single thought in others. She tells people, “You’re stronger than you think and you’re able to do so much more.”

8 . Astronauts drink their own pee (尿)—after it's been cleaned.     1     Many experts, though, argue that recycling pee and other waste is an excellent and safe solution when there isn't enough fresh water to go around.

    2     All of the water that astronauts use to drink, brush their teeth, or make coffee comes out of one limited container that has to be resupplied—from Earth. To help conserve water, the waste from sinks, toilets, and even the pee from lab animals on board flows into a recycling system. First, the water goes through a series of filters(过滤器) to get rid of large particles(微粒) and impurities. Then, chemical reactions remove poisonous chemicals and kill any bacteria or viruses.     3    

Chris Hadfield, who lived on the space station for five months, says, "Before you feel uncomfortable with the thought of drinking your leftover wash water and your leftover pee, keep in mind that the water that we end up with is purer than most of the water that you drink on a daily basis at home."

Astronauts, however, tend to be more adventurous than the average person. On Earth, cities in very dry parts of the world have attempted to introduce wastewater purification systems.     4     Citizens recoiled(退缩) in disgust. Despite scientific evidence that the water is clean, many people just can't get over the fact that it once flowed through a toilet. In the 1990s, activists in San Diego and Los Angeles campaigned against "toilet to tap" water.     5     In a survey of 2,000 Americans, 26 percent agreed with the statement: "It is impossible for recycled water to be treated to a high enough quality that I would want to use it."

10 . Who is a genius? This question has greatly interested humankind for centuries.

Let’s state clearly: Einstein was a genius. His face is almost the international symbol for genius. But we want to go beyond one man and explore the nature of genius itself. Why is it that some people are so much more intelligent or creative than the rest of us? And who are they?

In the sciences and arts, those praised as geniuses were most often white men, of European origin. Perhaps this is not a surprise. It’s said that history is written by the victors, and those victors set the standards for admission to the genius club. When contributions were made by geniuses outside the club—women, or people of a different color or belief—they were unacknowledged and rejected by others.

A study recently published by Science found that as young as age six, girls are less likely than boys to say that members of their gender(性别)are “really, really smart.” Even worse, the study found that girls act on that belief: Around age six they start to avoid activities said to be for children who are “really, really smart.” Can our planet afford to have any great thinkers become discouraged and give up? It doesn’t take a genius to know the answer: absolutely not.

Here’s the good news. In a wired world with constant global communication, we’re all positioned to see flashes of genius wherever they appear. And the more we look, the more we will see that social factors(因素)like gender, race, and class do not determine the appearance of genius. As a writer says, future geniuses come from those with “intelligence, creativity, perseverance(毅力), and simple good fortune, who are able to change the world.”
