This happened several weeks ago. On my way to work, I accidentally got on the wrong bus because I was1the news on my phone. I had to2and walk several blocks to work, a path I had never taken.

    I met a man sitting on a bench looking very 3 so I asked him what was wrong. He said his4had been dragged away (拖走) from a public lot and that he had no5to get to the airport to meet his wife. I told him that I could help him out and let him6there.

    I went to the7one block away and got cash. When I returned, the man was standing there, watching me8him. When I gave him the cash, he hugged me, thanked me, and started9!I nearly cried, too. I wished him to get to the airport safely, explained10he could take public transport to get there, and then continued to go to my office.

    I11at my usual restaurant for a to go (带走的) breakfast and, at the door, I met another man who12said, “Excuse me, sir. I don't want your money,13could you please help me get some food?” I said, “Of course, please come with me. ” I 14my breakfast and paid for this man's order. I15him a wonderful day.

    As you may16I was so thankful for putting 17on the wrong bus at the right time. This let me18two people who needed help and19. During each meeting, I never felt afraid; I only felt20to help them.

    Even though I've lived most of my life in China, English has always been an important part of my life.

    When I was four years old, my family and I1 to the US, where we lived in Houston, Texas, for a year. I was too 2 then to fully understand what it was like to be in such a different environment, but 3 English started to make its way into my life.

    At first, I didn't really know how to 4 with my foreign classmates with proper English, but they were nice and 5 and very soon English became like a second language to me. I could 6myself in both Chinese and English. I had another useful 7.

    English is 8 a tool of communication for me; it has also brought a new world of 9 to me. When I was in fourth grade, my friends 10me a very popular book series called Percy Jackson & the Olympians, and I felt then that I had never read any story that 11 me as much. I began to 12 the world of English literature（文学）and found that all the 13 books and stories I came across opened my eyes to a different 14 from the one I had been familiar with. I loved the stories I would otherwise have 15 if I had not known English.

    All in all, English has given me another tool for communicating with others, 16to understand and accept things I would never have 17 and brought me much 18through reading. I think I am very 19 to have learned English because it has helped20 my view of the world, and it still does.

    Chinese volunteers have completed a one-year test living in a simulated（模拟的）space lab in Beijing. The total length of the test, which started on May 10th last year, 1 370 days, thus setting a new record for the 2 stay in a simulated space lab.

    The space lab, called the Yuegong-1, or Lunar Palace 1, measures around 150 square meters. It 3 four sleeping rooms, a bathroom, a waste-treatment room and a room for raising animals. The Yuegong-1 provides everything humans need to survive in an environment 4 to that of a space station in outer space. Oxygen, water and food are 5 within it.

    A total of eight 6, all of whom are students at Beihang University, took turns 7 in the space lab. They were divided into 8 groups. On May 10, 2017, two men and two women 9 the Yuegong-1 for an initial （最初的）stay of 60 days. On July 9, they were 10 by another group of four, who stayed 200 days. The second group of students 11 on January 26, 2018, and the initial group12 and spent 110 days inside it.

    13, the volunteers were expected to stay in the Yuegong-1 for 365 days. But the project ended up 14370 days —from May 10 last year until May 15. The 15 five days were designed as a way to simulate a（n）16, in which the spaceship might experience a 17 in returning to earth.

    The goal of the project “Yuegong 365” is to 18 the limits of humans' ability to live in a 19 ecosystem for China's manned moon landing ambition. The success of the project means that China goes one step closer to putting 20 on the moon.

    Last week, Nicole Shen received a package from Amazon containing goods she had requested. She also found keys and an employee ID that had mistakenly found their way into her 1. At the sight of them, she knew she needed to get the 2 items back to their owner.

    After a little 3on social media, Nicole found out that they4Amazon employee Kenneth Delerme, who5 placed them in the box of items sent to Shen's Richmond, Texas home, about 150 miles away. Without his6, Kenneth had his car towed(拖) and was forced to sleep at a friend's apartment. So when Shen7to him explaining she had found his lost possessions, he was understandably 8. Throughout the course of their9on social media, Kenneth noticed people suggesting that he “swab(抽取血液样本)” as a way to10 Nicole. It was at that time that he got to know that Shen's 3-year-old son Roman. was diagnosed with a rare disease and was11 a bone marrow match(匹配的骨髓).

    In Roman's12, it means he can't produce white blood cells on his own. That means even a cold could 13 him. Therefore, the Shen family has been 14 a bone marrow match for Roman.

    Eager to 15, Knneth agreed to get swabbed and16persuaded several family members and friends to help as well. “All my friends and family are 17to help Roman or other people that need bone marrow,” he said.

    For Shen, this proves that despite the serious illness, the community isn't18 to help. And despite some cheats of social media, this story serves as yet another 19of how it can be used to do good and even save lives. Anyway, one good turn20 another.

    Sometimes people around you can change your life. The change may not be sudden or 1, but little habits can produce big 2 that make you think about what is important in your life. The person who changed my life is Julia Masi. She has 3 me so many things that I will carry with me 4 my life.

    One thing I've learned from Julia is how to balance 5. Julia has shown me how to 6 ahead so that I can finish all my school work, enjoy sports and 7 have time for my friends. She has taught me that you can do anything if you are 8 and if you never give up. I've also learned that you can find anything fun or 9 if you connect it with something that you enjoy.

    Last year I hated studying vocabulary, but I loved playing on my computer. Julia 10 the two and showed me a website called "freerice.com" where you can 11 a word game that gives you 5 grains of rice to donate to the poor with every correct word. She 12 me to learn a hundred new 13 by filling up the rice bowl. I liked playing the game so much that I 14 about 1, 000 words in just one month.

    Julia has always 15 me to try new hobbies. She showed me that going to the theater could help me become a better writer. 16, she taught me that discussing a play can excite an interest in reading.

    17 it wasn't for Julia I probably wouldn't have 18 how easy it is to help the poor. There are so many ways that one person can 19. I've learned to be more appreciative of what I own. I am 20 for the opportunities that I have been given. I will continue to think of ways to help those less fortunate for the rest of my life.

    I was a single mother of four small children, working at a low-paid job. Money was always1, but we had a roof over our heads, food on the table, 2on our backs. It was Christmas time, we3 downtown to see the Christmas lights, and enjoyed a special dinner, 4 the big excitement for the kids was the fun of Christmas 5 at the market. They talked and planned for weeks ahead of time, 6 each other what they wanted for Christmas.

    The big day arrived and we started out early. I 7 each kid a twenty-dollar bill and asked them to8for presents. Then everyone scattered (散开).

    Back in the car driving home, everyone was9 about Christmas, laughing and asking each other about what they had10 . I found my younger daughter, Ginger, had only one small and flat bag with her. I could 11 enough through the plastic 12 to tell that she had bought candy bars— fifty-cents candy bars！What did she13 with that twenty-dollar bill I had given her? I was so14. After getting home, I called her into my bedroom and closed the door. This was15 she told me.

    "I was looking around and thinking of what to buy, and I 16 to read the little cards on one of the Salvation Army's 'Giving Trees'. One of the cards was 17a little girl, four years old, and all she 18 for Christmas was a doll with clothes and a hairbrush. So I took the card off the 19 and bought the doll for her. We have so much and she doesn't have anything."

    My anger 20 and I had never felt so rich as I did that day.
