A month ago, my friend Nick and I experienced a(n) 1 event. It was the evening of the fourth day on our hitchhiking(搭便车) trip to Morocco. We were 2 on the side of a main road in the cold 3. It was nearly dark. To our 4, there wasn't a single bit of grass where we could put up our tent. Finally, we reached a small town after 5 for about an hour and a half.

    We found a bar where we thought we might be able to 6 ourselves first. Then we would 7 where we are going. We each bought a coffee, but the barman, José， brought over some bread 8. Full of thankfulness for his generosity(慷慨), we explained to him what we were doing. He showed much interest in our 9.

    Then, we asked José if we could 10 on his floor. We were very worried he would refuse. 11, he said yes! Thinking he lived upstairs, we waited for him to lock us in 12 he could be sure we didn't 13 anything. To our surprise, he gave us the keys! He showed us how the 14 worked, said goodnight and was off.

    We all stood in 15. In only a few hours we had gone from standing in the cold rain to owning a 16 bar. All the fridges were 17 and there was a fair amount of money on the sideboard. We were amazed at how much he 18 us. Then it was a good night's sleep. The next morning, he 19 and we let him into his own bar. 20, he gave us a free meal, and then we were on our way.

    There are many kinds of friends. Some are always 1 you, but don't understand you. Some say only a few words to you, but understand you. Many people will step in your life, but only 2 friends leave footprints.

    I shall always recall the autumn and the girl with the 3. She will always bring back the friendship between us, I know she will always be my best friend.

    It was the golden season. I could see the yellow leaves 4on the cool 5. In such a season, I liked walking alone in the leaves, 6to the sound of them.

    Autumn is a 7season and life is uninteresting. The free days always get me8. But one day, the sound of a violin 9 into my ears like a stream （小溪） flowing in the mountains. I was so surprised that I jumped to see what it was. A young girl, standing in the wind, was 10 in playing her violin.

    I had 11seen her before. The music was so nice that I listened quietly. Lost in the music, I didn't know that I had been 12there for so long but my existence did not seem to disturb her.

    Leaves were still falling. Every day she played the violin in the corner of the building 13 I went downstairs to watch her performance. I was the only listener. The autumn seemed no longer lonely and life became 14. 15we didn't know each other, I thought we were already good friends. I believe she also loved me.

    Autumn was nearly over. One day, when I was listening carefully, the sound suddenly16. To my astonishment, the girl came over to me.

    “You must like violin. ” she said.

    “Yes. And you play very well. Why did you stop?” I asked.

    Suddenly, a 17expression appeared on her face and I could feel something unusual.

    “I came here to see my grandmother, but now I must leave. I once played very badly. It was your listening every day that 18me. ” she said.

    “In fact, it was your playing 19gave me a meaningful autumn,” I answered, “Let's be friends.”

    The girl smiled, and so did I.

    I never heard her play again in my life. I no longer went downstairs to listen like before. Only thick leaves were left behind. But I will always remember the fine figure of the girl. She is like a 20 — so short, so bright, like a shooting star giving off so much light that it makes the autumn beautiful.

    One evening, Catherine was at home as usual. As her1swung between what she was going to do with her life and their dinner plans for the evening, she was unexpectedly2by an urgent call from her sister “Get over here! Turn on NBC and check these guys out. They are just like you…” One Facebook message and a phone interview later, Catherine3herself on a bus with 8 strangers in the middle of the sweltering desert heat of Utah, picking up trash and4awareness about zero-waste and climate change.

    With a deep5of the environment and a desire to make a6, Catherine, Davey, and a group of self7“environmental pick-up artists” went on a coast to coast road side trash pick-up. As they walked, sometimes only80.9 miles in an entire day, they 9 and steadily made their way across the United States for three years, picking up a total of 201,678 pounds of trash.

    Catherine and Davey10with us wonderful stories of hope and inspiration that fueled their11to continue their journey. After spending weeks silently12how she would have enough13to fly home for their two-week spring break, Catherine found a blank, unidentified envelope14with $850 cash in the desert. Just enough to get her home and back. After their bus15outside of Denver, they unexpectedly got16and arrived in Yosemite National Park three weeks later, just in time for the “Yosemite Facelift” where17from all over the state came together with a18of cleaning up trash all over the park.

    Being at the right place at the right time became almost normal, and they realized that much of what they 19was more than just a coincidence. Together, their team learned to simply 20themselves to their task, and surrender to the journey.

    I was at a crowded grocery store not long ago. It was a weekday evening, cold and tense. People were carelessly 1 aisles(过道) and at one point, two women 2 for several minutes after running into each other.

    Things got 3 at the checkout line. The cashier scanned a man's discount card, but he misread the savings on her screen as an additional 4. He decided she was acting 5 and began to argue. The cashier tried in vain to reason with him. She 6 a manager, who accompanied him to customer service and moved to the next 7 in line.

    We've all witnessed 8 scenes like this in public places. My reaction when I see them is both personal and 9. I am a sociologist who studies how and why people communicate with one another — or why they 10 not to. To me, the grocery scene was another example of how our 11 in others has declined. But it was also a teachable 12 on how we can rebuild our faith — 13 with just one person.

    I 14 the nervous cashier. I got a bottle of water from a nearby cooler and handed it to her. "I felt 15 about how that man treated you and wanted to buy this for you," I said. Her face lit up, and we 16 as she scanned our items. She told me she had been 17 that evening through severe foot pain and would be having an operation later that week. I wished her well in her 18, and she thanked me as I left.

    Those are the balancing 19 that will add up to restore (重建)trust between people. You can start that pattern in someone else's life, even in a 20 as ordinary as the neighbourhood grocery store.

An associate professor at Beijing Normal University has {#blank#}1{#/blank#}(expect) gone viral on the popular Chinese video platform Bilibili. The certified account has now amassed nearly 1.5 million followers in {#blank#}2{#/blank#} matter of days after {#blank#}3{#/blank#}(upload)the "Introduction to Social Sciences" course.

The unlikely rise {#blank#}4{#/blank#} fame began when a student shared a simple invitation flyer {#blank#}5{#/blank#}(hand) out by Chen. The flyer advertised the online course as "free, with no grades, homework, Q&A sessions or exams — just come {#blank#}6{#/blank#} you want to learn."

Chen's sincere {#blank#}7{#/blank#} fuss-free approach seemed to resonate. By March 28, over 5,000 people were simultaneously viewing his lectures at peak hours. The most popular video {#blank#}8{#/blank#}(surpass) 4.2 million views so far.

"My ability is limited, {#blank#}9{#/blank#} I try to be down-to-earth. Perhaps students are drawn to that," Chen reflected. He revealed spending over 5-6 years preparing the course content before finally recording {#blank#}10{#/blank#} over 3 months starting on New Year's Day.

Last year I moved to a new city with my husband and daughter. So during the first months we were busy getting 1 . This place is very different from where I lived before and we had a lot of 2 .

Then things were running 3 due to our efforts. So we decided to conduct a small ceremony at home in 4 of our success in adjusting to the new life. After the simple ceremony, we still had some food 5 . Our daughter suggested that she go with her father and look for someone who 6 all these food.

Hearing the 7 of my daughter, my husband offered to take her in his car to the nearby areas. But after a long time, they 8 to find a suitable one. They were about to return home suddenly when my daughter 9 an old man sitting under a tree. He looked 10 , tired and anxious.

My husband stopped the car and my daughter 11 the man and handed him the food packets. The surprised person looked at my daughter and asked if those item s were for him. When he listened to the 12 answer, he smiled, thanked my daughter a lot and started eating. After a short chat with the man, they went back home happily. The 13 on my daughter's face made me feel 14 a hungry human was a correct thing. It added to our happiness — I had the 15 to conduct an act of kindness.
