I got my first bike in 1943. It was an old, second-hand blue bike. Bikes of any kind were very1at that time. A new bike was rarely to be seen, as2was needed to produce weapons to3our brave men and women in the fighting overseas.

    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.

    I sat down at my desk and started writing a letter of thankfulness, but when it came to actually putting the letter into the mailbox... I 1 ...I couldn't do it. I suddenly felt a sense of 2and insecurity (不安).

    The letter was to an old teacher with whom I kept in 3 on Facebook. For months, I read about what she 4 on her Facebook page, which helped me to live my life differently. Her volunteer (志愿者) work wasn't huge. 5, she was doing small, local good deeds.6 , she changed my views on the world and for some reason, I felt I should let her know how her example7 influenced me.

    I could have easily sent her an email, but that seemed not enough for such an important thank-you. That's why I ended up8 the letter. But now here I was, standing before the mailbox, unable to put the envelope inside. What was stopping me? It suddenly hit me that I was 9 of being too nice. I guess I felt strange 10 it wasn't like she was my best friend or a relative. Maybe my 11 was too heartfelt. Thinking this over, I put the envelope in the mailbox 12.

    Weeks later I received a message from her. It turned out she was 13 a hard time and my note 14 a lot to her. She said she had no idea she was playing such a big 15in others' life.

    Not only did this letter make her happier, but her response to it brightened my world and 16my level of happiness as well. I was so 17 that it had such a great influence on her that I decided to write a(n) 18 letter to someone each month. Now it's easier for me to19 the goodness in others and be more20 for this beautiful life I'm living.

    I was nine when I arrived at the Children's Home in Nashua, New Hampshire. I failed third grade that year, and barely 1 it through a second time, and had squeaked through(侥幸通过) fourth grade by the time I reached Pauline Jambard's fifth-grade class at Charlotte Avenue Elementary School.

    I was 2 I wasn't as intelligent as the other kids. 3, Ms. Jambard took an instant liking to me. Of all the 4 in school, reading was my favorite. She would tell me, "Terry, you 5 reading. If you can understand what you're reading, you'll be 6 than most kids." After I read all the books in our program, I started reading the classroom's set of Encyclopedia Britannica(《不列颠百科全书》). And gradually I started to really 7 school life.

    That 8, our school threw a Christmas party for family and community members. My brother and I had no family to 9. I still remember looking up and seeing Ms. Jambard walk through the front door and 10 she was there to see me. I was deeply moved. That was the 11 Christmas of my life!

    After I graduated from Ms. Jambard's class, my brother and I 12, and I lost all touch with my teacher. Years later, I was on a business trip and had to drive through Nashua. I took a chance and 13 Charlotte Avenue Elementary School. I was walking toward her 14 when she came out into the hallway and said, "Terry!" It was as if I had 15 left! I was in seventh heaven on my flight home.

    We have stayed in 16, and I call Ms. Jambard at least once a year. Because of the 17 she instilled(灌输) in me, I went on to have a 18 career in engineering. I don't know if Ms. Jambard realizes how much she 19 me, but I'll never forget her 20 and faith in me.

The Fitting-in of Suzy Khan

    The first time I saw Suzy Khan, I knew I had to help her. She was really small for her age of 12. The boys in my class often 1 about her and laughed their heads off. She would open a book, pretending to read, with tears dropping on the open page.

    All I knew was that she was an orphan (孤儿) from Africa. She had just been adopted by a family in town who 2 that the best way for her to learn American ways of life was to be with American kids. I looked down at this 3 girl and promised myself that somehow I would help her.

    But how could I help her 4 in with us? There had to be a 5 .

    One day, when I went into the classroom, I saw that Suzy had 6 her geography book to a picture of a train, and in her notebook, she had made a(n)  7 copy.

    I was surprised and thought that she could do something in the coming 8 show. So, I took her to see the art teacher, Miss Parker, and showed her what Suzy had 9. “why, it's wonderful,” said Miss Parker, who then showed us a poster she had painted 10the talent show. “I need more of these, but I just don't have enough 11. Could you help me, Suzy?”

On the day of the talent show, Suzy's 12 were everywhere —- all over the hall and all over the school, each one different.

    “And finally,” said Mr Brown, the schoolmaster, at the end of the show, “we have a (n) 13 award. I'm sure you've all noticed the wonderful posters.” Everyone nodded. “One of our own students 14 them.”

    I could hear everyone whispering. “Who in our school could draw 15 well?”

Mr. Brown waited a while before saying, “16 this student worked so hard on the posters, she deserves a 17 , too. Our mystery(神秘) artist is our new student —- Suzy Khan!”

    Mr. Brown thanked her for all the wonderful posters and gave her a professional artist's set. “Thank you,” she cried.

    I 18, at that time when I was looking at her excited face, she'd probably never 19 anything in her whole life.

    Everyone started to 20their hands. Suzy Khan gave them a shy smile and the applause was deafening. I knew then Suzy was going to be all right.

    A few days after Christmas, my friend Zachary came over with his snowboard. Zachary was very good at snowboarding, but I could 1 do it at all. I wondered if maybe my new board wasn't the right size for me, so I tried 2 Zachary's board, but I still didn't get very 3.

    While I 4 with Zachary's board, he was making run after run down the hill. He asked me if we could go to his favourite hill to do more runs, and not wanting to 5 his fun, I 6 said I would go.

    While out on the new hill, I still struggled to stay 7. I had fallen a few times when a teenager that I had never 8 before noticed that I was getting 9, and called me over to give me some advice. I don't talk to strangers as a 10, but my mom was with me, so I felt 11. So I listened to what he had to 12, and then I made another 13. He watched, and then came over to give me more 14. I did what he told me, and I was able to get all the way down the hill without 15. It seemed much easier with the instructions he gave me.

    This guy was so nice and helpful about 16 me. He could have chosen to make a few more runs for the day, 17 taking the time to help me. As 18 preteens, sometimes when we think of teenagers, we think of those who are troublemakers, or those who scare us. But this teenager made me feel 19 around him and was really helpful and kind to me.

    I'm a much better snowboarder now, thanks to the very 20 teenage stranger.
