A few years ago, an elderly woman entered my video store, along with her daughter. The daughter was displaying a serious case of 1, 2 her watch every few seconds. If she had possessed a leash(绳子), her mother would have been 3 to it as a means of pulling her along to 4 the rush of other shoppers.

      I 5 and asked if I could help her find something. The woman smiled up at me and showed me a 6 on a piece of paper. 7 rushing off to find the DVD for the woman, I asked her to  walk with me 8 I could show her where she could find it and I want to enjoy her 9 for a moment. As we walked along the back of the store, I 10 its floor plan: old television shows, action movies, cartoons, science fiction. The woman seemed glad of the unrushed “trip” and 11 conversation.

      I said to her daughter, “ 12 some advice?” “Of course not,” said the daughter. “13 her ,” I said. “When she's gone, it's the little 14 that will come back to you. Times like this. I know.” It was 15 . I still missed my mom and remembered the times when I'd used my impatience to make her 16 .

     Together they made their way toward the store's resting area. They sat there for a moment, side by side, 17 the holiday crowds. Then the daughter 18 and immediately regarded her mother lovingly. And slowly she placed her arm with 19 unaccustomed affection around her mother's shoulders and 20 guided her back into the crowd.

    It's hard being an astronaut's son. I mean, everybody expects you to be special or 1. But I'm just a common student, and I' m common in all kinds of ball games, too.

    I often wonder 2 my father ever had a son like me. He' s so special and so good at 3. So I used to dream about doing something special to make him 4 me.

    In one class, my teacher 5 a Father's Day essay contest to us. He also told us the winners' essays would 6 in front of all the parents and students. After school I walked home, 7 my father, who I would write about in my essay.

    I still remember he stayed by my side in the 8 when I was a little kid and had an awful dream. He surprised me 9 a new puppy dog at my eighth birthday party. He sat and tried to explain the meaning of life to me when Grandpa Bob died. To me, he wasn't a world-famous astronaut, just my dad.

    I wrote about all these 10 in my essay. One of our classmates said, "I believe you'll win the contest, David. You're the only one in our school who 11 write about being the son of an astronaut. "I shrugged(耸肩). I hadn' t shown anyone the essay, but now I 12hoped I wouldn't win. I didn't want to win just because my father was an astronaut.

    I won the second prize. 13 I finished reading my essay, the whole school applauded(鼓掌). I saw my father blowing his nose. I went back to my seat. Dad nodded to 14, cleared his throat, and put his hand on my shoulder. "Son, this is the most 15 moment of my life," he said. It was the proudest moment of my life, too. Maybe I'll never be a great hero or win a Nobel Prize, but just then, it was enough just to be my father' s son.

    I don't know your name, and I'm guessing that you are about high school age. I 1 you in action yesterday as you saved a little boy from 2 at Lake Elmo beach.

    I was sitting on a bench with my friends3 their children played in the water. I remember4you taking off your shorts, grabbing your 5 device and heading into the water. My friends and I noticed at that moment the little boy's 6 moving up and down. He couldn't have been more than two years old and 7 to be alone in the water.

    You got to him, put your flotation device around him, and 8 him back to shore. We could see the boy was 9 as you carried him out of the water and laid him on the 10. You started doing compression（按压）on his chest, and that is when we knew it was a bad 11We reached you and knew you needed 12I picked up my phone and dialed 911.

    Soon, the ambulance13 and several doctors were there to assist you. You appeared 14 as you walked away, as anyone would be. I 15 if this is your first rescue — it doesn't matter. What you did was heroic, and I 16 you.

    Had you been a few seconds later, this 17 could have ended quite differently. You were alert and18 what was going on in the water, responsible for watching over a hundred kids at that time.19 your fear, you took action. Because of you, the little boy and his family are 20together today.

    In our discussion with people on how education can help them succeed in life, a woman remembered the first meeting of an introductory1 course about 20 years ago.

    The professor 2the lecture hall, placed upon his desk a large jar filled with dried beans, and invited the students to 3how many beans the jar contained. After 4 shouts of wildly wrong guesses the professor smiled a thin, dry smile, announced the 5 answer, and went on saying," You have just 6 an important lesson about science. That is: Never 7 your own senses."

    Twenty years later, the 8could guess what the professor had in mind. He 9himself, perhaps, as inviting his students to start an exciting 10 into an unknown world invisible to the 11,which can be discovered only through scientific 12.But the seventeen-year-old girl could not accept or even 13 the invitation. She was just 14 to understand the world. And she 15 that her firsthand experience could be the 16.The professor, however, said that it was 17.He was taking away her only18 for knowing and was providing her with no substitute." I remember feeling small and 19"The woman says," and I did the only thing I could do. I 20 the course that afternoon, and I haven't gone near science since."

    Until a few years ago, I had what most people would call a good life. I had a 1 job that paid the bills; I had a good family that I was close to, and I had a place to live and money in the bank for trips and 2, and there was nothing much wrong in my life. 3, I was bored.

    I wanted more. I wanted to live 4 and loudly and make sharp memories instead of the 5 ones of everyday life. But I was 6. I had never had any 7 in myself. As a child, even buying something in a shop caused me a great deal of 8, and even though I did get better as I got older, I never quite 9 that childhood shyness.

    And I tried everything, like reading books about confidence. I also took tiny steps leading to my goals. But none of them really 10.

    So I 11 that the small steps weren't enough. I signed up for an internship (实习期的工作) of teaching English in Vietnam, an 12 huge step, one that 13 me as much as it excited me. And then the day came and I left my home and my loved ones. I was alone in a country where the food was 14 and the streets were unfamiliar. I had no idea whether I would be able to 15 everything that this very strange environment would 16 at me.

    I spent five months in Vietnam, teaching, exploring and laughing, I'd learnt to 17 myself, my skills, my abilities and my decisions. I returned home 18, even to myself, let alone to others. The 19 that had controlled my life and the self-doubt were 20.

    That one big chance changed everything for me, and in me.

    For years, one teacher from a(n)1 village in Kenya(肯尼亚) has completely devoted his life to his job as a teacher and has made huge sacrifices (牺牲) for his 2. For the past 12 years, Tabichi has worked as a teacher in the hope that his lessons will give students a(n) 3 to improve their situations. 4 , working at the Keriko Mixed Day Secondary School hasn't been 5 .

    According to Tabichi, the school has no library or laboratory. What's worse, the teachers that work at the school have to 6 in crowded classrooms. Instead of 35-40 children per classroom, teachers are 7 to teach a group of 70-80 kids at one time. Therefore, the students aren't able to get the attention and guidance that they need. More 8, the school facilities (设施) are not the students' only 9. Most of the students in this school come from very poor families, so even 10 breakfast is hard for their parents. One of the other major 11 that Tabichi faces is keeping kids in school as long as possible. Many of the students in that area have difficulty completing their education because of poverty, 12 when Tabichi gets the feeling that a student is at risk of dropping out, he will work to 13 their families to put more value on education.

    14 his tireless work, his students have made lots of 15 in their studies. In recent years, his students have 16 many national and international science competitions. Tabichi is 17 that his students can be so excellent. In March of 2019, Tabichi was 18 by the Varkey Foundation and won a $1 million prize. He was 19 as "the best teacher in the world". The founder of the prize, Sunny Varkey, says he hopes that Tabichi's story will 20 more people to enter the teaching profession.
