I never forget the single act of kindness that changed my life over 25 years ago. During a vacation trip, I needed to find my 1 to the Greyhound bus station, some 30 miles away. Being a 2student, I had little money to get there.

    I3to call various taxis and shuttle（往返汽车） services but they were all to4or too far away to pick me up. Then, I got one person on the5who managed to make out that I needed a ride to the Greyhound station but only had limited financial 6 and he agreed to transport me! He came to pick me up about 45 minutes 7. The driver was older and I remember8why the shuttle didn't have a meter (计时器) but his ID was there and I could see this was his9. The driver was so kind. He knew I was10so he distracted me with stories and good11. He said I looked like his granddaughter.

    At one point, I asked him why he12so little to the others. Then, he patiently explained that he was13retired and hadn't removed his number from the phone book but when I called, clearly upset, he felt 14to help. This man drove an hour out of his way to help a person he didn't know for a fee that only15his gas, if that! Because of his 16, I knew things were going to be okay. This man's kindness warms my heart every time I think of him. 17 , I didn't get his name and his face has18gradually from my memory but he is on my mind often and I wish I could thank him19 "Thank you Mr. Angel Shuttle-Man! I hope your granddaughter knows what a(n)20grandfather she has!"

    As she walked round the large shop, Edith realized how difficult it was to choose a suitable Christmas 1for her father.

    She 2that he were as easy to please as her mother, who was 3satisfied with perfume(香水). 4, shopping at this time of the year was a most 5job. People 6on your feet, pushed you with their shoulders and almost 7 you over in their hurry in order to 8 something cheap ahead of you.

    Partly to have a rest, Edith paused in front of a counter, where some beautiful ties were on 9. "They are 10silk," the shop assistant told her with a smile trying to 11her to buy one. But Edith knew from past 12that her choice of ties hardly ever pleased her father.

    She moved on slowly and then, quite by chance, 13where a small crowd of men had gathered round a counter. She found some fine pipes on sale and the 14were very beautiful. Edith did not hesitate for long, although her father 15 smoked a pipe once in a while, she believed this was 16 to please him.

    When she got home, with her small but 17present hidden in her handbag, it was time for supper and her parents were already 18table. Her mother was in great 19. "Your father has at last decided to stop smoking," she told her daughter happily. Edith was so 20that she could not say a single word.

    On a recent trip to California, I was introduced to Smile Cards. I promised myself to 1 an act of kindness before I left California. I 2 thinking about it but I didn't know what to do.

    I reached the airport and the 3 was about to begin when I saw an ice-cream store. I went in and told the guy at the store that I 4 to do an act of kindness. The guy, named Jose, looked confused. 5 I explained I had just attended a conference, where I was told Smile Cards and 6 to do an act of kindness. Jose showed 7. I told Jose, “Whoever is your next 8 , treat them to some ice-cream and then give them this Smile Card.” Jose 9 read the card and agreed with a smile that was both grateful and 10 at the same time.

    Since this was my first time, I wanted to know the 11 of the receiver. “Jose, I have to catch a 12, but here is my cell phone number. Would you be 13 enough to call me and tell me the person's reaction?” He 14 .

    I went to my gate, and as I was about to board, Jose 15. “I did the act of kindness. The person was very 16, and asked me to express thanks to the person who paid for them!” I again thanked Jose and boarded the flight feeling 17.

    I really want to 18 this practice of kindness. I am a professor and I love my work 19 it makes a difference in the lives of others. And now, I realize that I can do that everywhere. The whole world is my 20.

    If we redouble our efforts, our dream will come true. Chen zuobin had1for 13 years already. Finally, he decided to become a2again. Born in a mountain village in Anhui province, Chen Zuobin walked out of the3 for study when he was 19. Though he had a4life as a creative director of an international agency in Shanghai, he couldn't5the anxiety appearing in his dreams. "I6about countless branch roads several times a year, I didn't know which one leads to7. It made me feel terrible." One day, Chen Zuobin woke up and said to his wife," I want to go home."8being surprised, his wife said, "9your heart. Don't worry about me. "

    The young couple returned to their hometown and10the Real Food Farm just to lead a real and simple life. Chen Zuobin shook off the11and tiredness from too much12in the city. Only in the mountains can they enjoy the13air. There isn't the smell of tail gas, but the smell of14when it shines over the woods. They live a life of "eating healthily and15well."

    In a time when eating 16 becomes a luxury (奢侈)in the 17 life, it's truly a right way to return to the 18. "Life is a journey of19the proper way. " said Chen Zuobin.

    Those dreams about branch roads have 20 because he has found his own path.

    As we all know, helping others is a great service, and it's easy to see how to help some people, but what about those people whose needs are not so obvious? This story may have happened a while back—It was a lesson which has1with me and helped me ever since.

    It was Thanksgiving and I was volunteering with my parents at a2for the needy. We stood behind the counter3out hot food to whoever came in. Most of our diners looked like they had been having4times: their clothes were old and dirty.5short, they looked needy!

    Then, a man came in, who looked anything6needy. He was well dressed; he wore a/an7suit. I wondered what he was doing there and my jaw dropped in amazement when he 8the line for food. The closer he came to my service station, the more I9. What was this man doing? I wanted to know. Surely he was not going to take food meant for those who were really in10!

    Then my11quietly took me to one side. She said, "You12that the needs of the people who come here must be purely13: hunger, inadequate shelter, clothing, etc. And this gentleman doesn't seem to have any of those problems.14what if he needs emotional help? What if he needs15, or just to be among other human beings?" Her words16me like a ton of bricks! I felt like I should apologize to the man—but I didn't.

    About a week later, the shelter17a large donation from an anonymous(匿名的)person. I can't help but18if it came from that man.

    Now, whenever I meet someone I remember my mother's19and try to send kindness and blessings their way, regardless of how they look. Needs aren't always20. But kindness always makes a difference.

    Do birds have a favorite color? It's probably not a question you've ever 1 but a project designed to answer that question led to two British schoolboys 2 the Young Scientist Award of the year after presenting their 3 to a group of judges.

    The boys' 4 to find out whether birds have a(n) 5 for a particular color came purely from scientific curiosity. Both of them are very 6 about nature and the power of colors in things, 7 they worked as a perfect combination and 8 a citizen science project that didn't require fancy equipment.

    The boys 9 bird feeders in their back gardens. Each garden had five feeders, colored blue, green, red, yellow and transparent. They made sure to change the position of the feeders regularly, 10 it affected the results and then placed a 11 for an hour each morning, afternoon and evening across all four seasons to 12 birds visiting each feeder. They collected 13 covering a total period of 400 hours.

    When the experiment finished, they had recorded the birds' 14 to the gardens added up to 3,205, with over a third being to the 15 feeders. It was a conclusive win for blue. The pair believe that blue is 16 to birds because of its familiarity, while red and yellow are often 17 of poison in nature.

    Later, the boys considered 18 for their findings, such as using the less popular colors of red and yellow to 19 bird strikes on planes. There seems to be quite a strong connection between the 20 of planes and the number of bird strikes.
