People often said Thomas Edison was the greatest genius(天才) of his age. There are only a few men in all of history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be pleased only because someone said he was a genius. “There is no such a thing as genius,” Edison said. He thought what people called genius was mostly hard work.

     But Edison was a thinker as well as a worker. From his earliest days as a child he wondered about the secrets of nature. He tried to understand them, and then he tried to learn what he could usefully do with them.

     Edison enjoyed thinking. He knew that most people would do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking could give men enjoyment and pleasure.

     Edison could not understand why anyone could not be interested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what idea he had about life. “Work,” he answered, “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.

    In the ancient Arabic story called Ali Baba and the Forty Thieves, the young hero Ali Baba said "Open Sesame" and a door to hidden treasures was opened to him. The old story had a special meaning for Ma Yun. He drew inspiration from it for Alibaba.com--Chinese largest ecommerce(电子商务) website.

    In 1995, Ma Yun was working for a US trading company when he was introduced to the Internet. "I know nothing about computers and has never touched a keyboard," he said. He searched the word "beer" and nothing came up about Chinese products.

    Ma Yun had an idea. Why not build a large Internet market to connect customers with companies from all over the world? They could do business online in that way. That was how Alibaba began. His company grew quickly. But that didn't mean everything went smoothly. In 2000, many Internet companies failed including Alibaba. But later, he was successful because he managed to attract investment(投资) into his company. "You should stick to your dream," he said. "Everyone thought I was daydreaming when I started. But the most important thing is that we believe in our dream from past to today and tomorrow. Of course we made many mistakes, but we never give up."

    Ma Yun is also smart. For him, success in business is like trying to catch a rabbit. "If there are nine rabbits, focus on catching one--don't try to catch them all," he said. "Change your ways if you need to, but don't change the rabbit. Get one first, put it in your pocket and then catch the others. "

    "Mom, I'm bored," said Jason. "There is nothing to do." "You can clean your room," said Mom. "That's not fun." It was only the second week of summer vacation. It was still too chilly to go to the pool, and Jason was tired of watching TV. His friends went on a trip, and even his dog, Riley, was being lazy.

    Mom was getting ready to go downtown to the food kitchen to help out. She volunteered three times a week serving lunch to people that weren't as lucky as Jason. "Why don't you come with me to the food kitchen and help out?" Mom asked. "I don't know anything about working at a food kitchen," said Jason. "You just watch me, and then you will see how to serve the food," said Mom.

    It was time to go, and Jason was excited to try working in the food kitchen. He watched his mom put some chicken on a plate and some mashed potatoes. She then passed the plate to the next lady, and she put some green beans and bread on the plate. "I can do that," thought Jason. One of the volunteers left early, so Jason took his place in the serving line. He was in charge of putting salad on the plates. He served twenty-five people that day. After the kitchen closed, Jason and his mom stayed to clean up. "That was great!" said Jason.

    Jason was so excited and really enjoyed his day at the food kitchen. He couldn't wait to get home and tell his dad about how much fun he had. "Not only did it give me something to do, but I felt so good doing it," Jason told his dad. "Jason, that was nice thing you did today," said Dad. "You helped many people who aren't as lucky as you to have a hot meal," Mom said. "I am so proud of you, Jason! You worked very hard.

    Jason went to bed that night thinking about the food kitchen. "I am going to help out again," he thought. Jason made some new friends, and he didn't even know they lived so close to him in town! The best part was how good Jason felt inside.

    My name is Jack. When my family moved to America in 2014 from a small village in Guangdong, China, we brought not only our luggage, but also our village rules, customs as well as culture. One of the rules is that young people always respect elders. This rule, unfortunately, led to my very first embarrassment in America.

    I had a part-time job as a waiter in a Chinese restaurant. One time, when I was serving food to a middle-aged couple, the wife asked me how the food could be served so quickly. I told her that I had made sure they got their food quickly because I always respect the elderly. As soon as I said that, her face showed great displeasure. My manager, who happened to hear what I said, took me aside and gave me a long lecture about how sensitive Americans are and how they dislike the description "old". I then walked back to the table and apologized to the wife. After the couple heard my reason, they understood that the problem was caused by cultural differences, so they laughed and were no longer angry.

    In my village, however, people are proud of being old. Not so many people live to be seventy or eighty, and people who reach such an age have the most knowledge and experience. Young people always respect older people because they know they can learn from their rich experience.

    However, in the United States, people think "growing old" is a problem since "old" shows that a person is going to retire or that the body is not working well. Here many people try to keep themselves away from growing old by doing exercises or jogging, and women put on makeup, hoping to look young. When I told the couple in the restaurant that I respect the elderly, they got angry because this caused them to feel they had failed to stay young. I had told them something they didn't want to hear.

    After that, I changed the way I had been with senior citizens. It is not that I don't respect them anymore; I still respect them, but now I don't show my feelings through words.
