    Challenges of my Life

    Many high school students tend to follow the crowd and not to do what they believe to be the right thing. I was one of them. It took me two years of high school to realize that I was capable of standing on my own two feet and taking up the 1of wrestling, which has had a long history in my 2.

    The tipping point(临界点) for me was the constant urging of my family to 3  I can remember my grandpa telling me the story of 4he  won his championship match and the 5he had when they announced his name as New York State Champion. I never could have 6that feeling till the night I won my first match. The one thing that scared me away from this sport was the 7 which was a tight fitting singlet that exposed my entire body. I also never realized the 8demand that wrestling took—the long hours of learning new moves and lifting weights. And the mental 9for this sport is overwhelming, too. Also, I had to learn to10my time between school, home, work, family, and friends.

    Wrestling is more of an individual sport but it also 11the help and support of a team to be successful. The coaches taught us to 12ourselves and also the opponents that we face on the mat. 13a team at Christmas, we were able to bring toys to Upstate Hospital cancer unit for the 14children who were facing a major illness and could not be home for the holidays with their families. This taught me a valuable15not to be afraid of those things that frighten me. It also made me 16that I need to live each day to the fullest.

    Wrestling has 17me that I am capable of being my own individual. The  18 that I have gained has allowed me the possibility of furthering my wrestling 19later. From this sport, I now know that in order to be 20you must not be afraid to try something new.

    The Best Time to Visit These Pricey Destinations

    If you're going to shell out on a vacation, then you might as well do it right. With that in mind, we've asked a few experts for tips on when to visit some of the most expensive places across the globe. Here's what they had to say.

    Botswana

    Hotels in Botswana are second only to Dubai in terms of average cost per person, per night, at around $257. To make the most of your time there, consider an autumn visit, suggests Sarah Faith of Responsible Travel. “The heat peaks in October—this is the best time to go and see wild animals as they gather around in the Okavango Delta”, says Faith. While wildlife viewing is incredible in Botswana, there's much to enjoy away from the wilderness, too.”

    New York City

    New York is the second-most expensive holiday destination overall and the most expensive place to dine out, with an average meal for two costing around $67. Garrett, the CEO of Discover New York, suggests, “October and June have gorgeous weather, so outdoor activities are a good choice, with sailing, in-depth neighborhood walks and biking.” For great value, she advises traveling in January and February, when the city offers tons of indoor activities, from art galleries and Broadway shows to indoor sports events and thousands of dining options.

    Sydney

    With its incredible surfing beaches, dining scene and friendly locals, Sydney is always a favorite of travelers. It's also expensive. Generally, the shoulder seasons (fall and spring in the U.S.) have the most comfortable weather and fewer crowds than the December-to-February high season. But some months have particular appeal, according to Stuart Rigg, Australian travel specialist for Southern Crossings. April, for example, falls into the low season, which means you'll find hotel deals along with weather that's typically “very pleasant,” Rigg says. “Sydney also has some great events during this low season period,” he adds.

    London

    Petulia Melideo, who runs Context's London walking tours, advises booking well in advance for lower hotel rates, and suggests a wintry visit. “November is a great time for London. The weather is still tolerable—and if it gets too chilly, there are plenty of cozy pubs to pop into,” she says. Other good times to visit include June, which means fewer tourists.

A Blessed Teacher

    I remembered Ricky came back to see me ten years after he was in my class. He told me how I had inadvertently(不经意地) changed his life.

    Ricky often gazed out the window during one of my ninth-grade history classes early in my teaching career. He was quiet, and his good grades and mild manner were why I did not move him away from the seat by the window.

    One day, I leaned over his shoulder and quietly asked, “What are you looking at? You gaze out of this window during every class.”

    He said, “I am looking at the band.”

    According to Ricky, I said, “If you like the band so much that you have to look at them during this class every day, I want you to go down to Mr. Overby (the band teacher) and tell him that I sent you. Tell him that you want to be in the band. Now turn around and finish working before the bell rings.”

    The next day Ricky went to Mr. Overby and told him I had sent him and he wanted to be in the band. He added that he did not know how to play any instrument.

    When Ricky visited me ten years later, he thanked me for telling him to go to Mr. Over by because he fell in love with music and discovered his musical talent that had not been tapped. His musical talent resulted in him getting a scholarship to college and earning a degree that now allowed him to provide for his family. Most of all, music had brought great pleasure and satisfaction to his life.

    After Ricky thanked me, I pointed out that he did all of the hard work it took to become the wonderfully talented person that he was. I did not make him walk downstairs to join the band, practice his instrument, and get the good grades that led to his college scholarship.

    Ricky responded that I could have yelled at him for looking out the window. Instead, I gave him an alternative that changed his whole life.

    After he left, I thought about his words. I realized that I was teaching children with every word I said, every action I took, and with every decision I made. Ricky's story raised my teaching bar. Most of all, I have never forgotten the lesson Ricky taught me, a blessed teacher.

    Global GDP in 2030 will be 14% higher as a result of AI (Artificial Intelligence), thanks to improving labor productivity and increasing consumer demand, says a report.

    The report could increase the enthusiasm of economic policymakers and the public, and show the power of technology in changing not only people's daily lives, but also economic activities. However, history tells us that, while technological advancements have brought us benefits, they have also led to great social disorders, by changing the production and labor structures, and forcing many workers to either adapt to the changes or lose their jobs. In the 18th century, for instance, skilled workers rose up to resist the Industrial Revolution, destroying machinery in the early 19th century. We may not see similar protests today, but history should serve as a warning against the application of AI technology.

    While we may gain a lot of benefits from AI, we must work out plans to reduce its negative effect on society, especially for workers. AI can raise productivity and expand GDP, but it can also make non-adaptive workers jobless. In India, some technology personnel have already felt the negative effect of information technology. As technology industries across the world seek increasing support from automation（自动操作）, robotics and big data analysis, some technology workers have already lost their jobs.

    In their 2013 research study, Michael Osborne and Carl Frey from Oxford University estimated 47% of the jobs in the United States are “at risk” of being automated in the next 20 years. They said jobs in transportation and office and administrative support are at high risk of being automated. And Kaifu Lee recently said that robots could take away about 50% of all jobs from humans in the next decade.

    Those estimates may sound sensational and the impact of technological advancements may not be that serious, as they will also create jobs in new industries. However, policymakers should consider how to better embrace the technological wave to bring benefits while taking action to minimize its negative effects. The government therefore needs to work together with business leaders and social organizations, to promote training programs for potentially helpless workers, in order to make them more capable of adapting to the structural changes in industries and job markets in the future.

Read the following passage and then answer the questions.

    When thinking back to an experience that has affected me the most, I can't help but recall the first time I performed for a crowd with my band.

    As I stood in the dark, in front of 300 people, my head began to pound and my eyes began to hurt from straining to see the faces before me. No matter how many times I wiped off my hands, they were covered with sweat, making them fumble across the strings of my guitar. Then, in a flash, the spotlights were turned on and the crowd yelled. My heart raced and I knew that the night of my first concert would be exciting and memorable.

    The concert was held annually at Frank's school. Being the largest activity for the students in the spring, we were told to expect the whole school to come to see us play. That fact went over and over in my mind. True, I had played in the school band in concerts for many people, but that was with a large group and I had sat in the back. Here it was just the three of us, all up front. I had had different visions of what performing would be like, but what ended up happening was a pleasant surprise.

    During the first song, the crowd stood in a mixed state of confusion and excitement. I could see nothing but their dark shapes, some swaying to the beat of the bass drum, others standing still, examining our every move. The song ended with hesitant applause.

    Glancing at Frank, the guitarist and singer, I read a message in his eyes. "I don't think they like us." His look pierced through my heart and I almost left the stage, yet kept going anyway. The second and third songs went the same way with the crowd looking at us like monkeys in a zoo. But then the magic started.

    Our fourth song we had was written for the occasion and it was as if it were the beginning of a trip that we would take with the crowd of onlookers. The funk bass and driving drums seemed to pick these people up like puppets and do with them what they pleased. The crowd danced and jumped and clapped, in and out of beat. Our music was giving these people a reason to lose their inhibitions and for a short time, enjoy themselves. By the end of the second to last song the crowd was at our mercy. Finally creating a situation that I had only dreamed of, during the last song the crowd began to sing the words. But it was not just any song, it was a song we had written. This sent my heart racing and I couldn't help smiling and even laughing. The song ended and an echoing roar came over the crowd.

    The concert was to me part of a childhood dream. My friends and I were responsible for giving 300 people a good time for an evening. They sang my words and they hummed my tune, and all helped to make the dream come true. That night back in my room, I sat up all night. I saw the bodies dancing in front of me and heard their screams. Even though I may perform in college and in the future, this feeling is one I may never feel again.

    As a child, Wang Junyan never dreamed of becoming a famous person on TV. However, she is the presenter for Universe TV news programmes. She told me that, working hard and believing in what was true made her success. Her mother was a strong character. She worked extremely hardthrough school. Her attitude towards life will never stop influencing her thoughts and actions. After graduating from university, Junyan chose to be a journalist to help the people and the governmentand catch the guilty people. It wasn't easy but she never gave up. Thisbecause she won an award for her report. When asked about her secret to success,she told us, “Nothing that I learned from my mother has ever left me. Today when I'm looking for stories, I still feel like I am turning over stones to see what might be hiding beneath!”
