Recently, my family and I visited Kaikoura, a coastal town in New Zealand. The first evening it seemed a1 place, but the next day I remembered what I'd 2about it in a magazine. It was often 3 to see dolphins (海豚) and whales there!

    My family and I 4  on a grey, windy morning on a small boat. 5, the sky turned blue ten minutes later. Soon we  6 the place where we were supposed to go swimming. To my 7, this was more than 40 km from land. I was quite 8by this time, and wondered why we came all the way out there, when 9someone shouted “Dolphins!”

    All I could 10were fins (鱼鳍) everywhere — there were about one hundred dolphins, all 11towards our boat! Many of them were jumping around in the water12they were asking us to come and play. I 13my snorkel (潜水通气管) and jumped into the sea. Then I tried to make 14in the water to attract them. What made me 15was that they heard me and came to swim around me. Amazingly, a dolphin kept following me, but then changed his 16and swam in another direction. It really made me realize how 17these animals are.

    About an hour later, it was time for us to get back onto the 18. I really enjoyed myself, but I was a little cold and 19 to leave the water. I noticed that everyone on board was smiling and I realized what a very20moment we'd had.

    I have written a poem called Flying Kites, in which a man 1 his son to fly a kite. After a few minutes, the child2 drops the string and lets the kite soar(高飞). With joy in his eyes, he watches it climb until it disappears 3.The father realizes that 4 he'll have to loosen the string that ties him to his son. And he 5 ,“Will I release the tie as unselfishly as that?”

    Many years later my son, Gary,6 he wouldn't finish his college career. I tried to talk him out of it. But none of my reasoning made any 7 . At the end of the semester Gary moved back home.

    Gary managed to find a job at a nursery and went at it with 8enthusiasm. I,9, was deeply disappointed. What was a college professor's 10  doing at a job that any high school dropout could perform? Then I tried to11 him. “Look,” I said, “In a few years you'll be at your high school reunion with 12 classmates who became doctors, lawyers, and engineers. Do you think you'll be able to 13 that?”

    “Yes, Dad,” he replied without 14. Then he fixed his eyes on mine and said, “But the real question is: Can you?”

    Shame suddenly 15 me. I wasn't thinking about my son; I was thinking about myself and what my friends would think. The problem wasn't Gary's pride; it was mine. All at once I remembered my  16  and the question it asked “ Will I release the 17 as unselfishly as that?”. At that moment I knew I had to let go. Gary was  18 enough to make his own choices.

    Today Gary has a successful career working for the city. I am very 19 of who he has become.20I let go of my pride, I've been able to sit back and enjoy watching him soar.

    “He who 4 is the owner,” William said in the 5 remarks of the cleanup event in 2000.“The Great Wall 6China, and is also one of the greatest 7 in the world.Everyone has a 8 to protect it.Every day should be Earth Day,” he said.

    During the past three decades, he has spent most of his time 9 and exploring the Great Wall and has developed his own 10 to protect the cultural relic.

    “It's a 11 thing that people are going out to enjoy themselves and to 12 the great history and heritage, 13 it's also quite dangerous if they don't 14 how fragile (易损坏的) the historical sites are and how fragile the 15 is,” William said.

    At the age of 14, Harvey Bay teenager Mark Farrell took a dive into a swimming pool that would 1 his life forever.

    “I jumped into the pool and broke my 2,” he says. It's a very 3 story because I jumped into the deep end, not the shallow end where most spinal (脊柱的)4 occur.”

    Mark has been in a wheelchair ever since and now, at 27, is very matter of fact about any 5 life might throw at him. In fact, he finds it 6 to name any challenge at all. “I just live my life and 7 it day by day,” he says.

    For the past few years, Mark has 8 with the Spinal Education Awareness Team (SEAT), telling his 9to young people in the Harvey Bay region. He also works as a whale 10, taking photos for various publications and calendars. “If I can 11 one kid's life, it makes every single 12I do worthwhile,” he says.

    Mark discusses the importance of checking the 16 of water before diving in and being more 17 in general. He has told thousands of school students his story over the years and says that if his 18 can prevent one spinal injury in a young person, he's 19. Mark's contribution to preventing spinal injuries was 20 in 2017, when he was named Young Australian of the Year.

    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.

    Dealing with a disability can be a difficult task for anyone, but it's nothing for Roger. Having double disabilities all his life has made life a forever1. Roger was born prematurely (早产)and2in the hospital for nine months after birth. He was3of any other medical issues that he suffered at that time.

    Roger knew that he had poor4when he was a little boy. In school he couldn't see clearly what other5did, so the Library for Blind and Physically Handicapped provided him with large-print6and audio cassettes. He had barely graduated from high school due to the7of earlier assistance in high school. In 2008 he lost the remainder of usable sight8. The loss of vision was because of Graves' disease. He did not know he had it9he went to a specialist.

    As for his secondary10, his legs have given him difficulty all his life due to injuries. He severely broke his both11at 5 years old owing to falling on the ice. At that time he was too12to receive special surgeries (外科手术). As Roger gets older, he has had four surgeries on his knees. Even though the surgeries are all successful, Roger cannot13as common people do.

    To this day, it is a daily battle and he continues to14. Roger won't sit around and says if he only lives in this way, this is a15of his time. He never16, because he always believes that disability does not17incompetence. Roger always tries his best to enjoy every day and realizes his18or goals. By teaching Braille (盲文)and working at his local community, now he is famous in the US. Whoever you are, you can always try to do19good for other people, which makes your life more20.
