Rodney Smith, Jr. started mowing the lawns (割草坪) in Huntsville, Alabama last fall. He used his time between classes at Alabama A&M to reach a goal of mowing 100 yards before winter. Smith has been cutting grass for free to help single moms, the elderly, and the disabled, while teaching the local youth the values that can turn boys into men. “I'm doing something positive. I want boys to follow me and be better than me,” he wrote on his Facebook page.

    Rodney is from Bermuda. He says people there help each other and are always friendly. “That's what drives me to help people.”

    In May this year, he was getting ready to launch his mowing service for the summer when he heard about a 93-year-old woman trying to cut grass by herself. Smith and a friend showed up to do the job for her.

    In November, a local TV station gave him $300, calling it a special gift for his good work. After he received the money, he used it to create the non-profit(非盈利的) service group, Raising Men Lawn Care Service. He also started a page to collect money to buy lawn equipment and other things—including T-shirts with special logos.

    After I read about Rodney's story, I told my friends about him. We also planned to mow lawns for single moms, the elderly and disabled in our neighborhood. And I hope more and more young people will join Rodney's service group—Raising Men Lawn Care Service.

    It was close to midnight and it was unusual to see vehicles on the road. However, several trucks pulled over and workers silently unloaded camera equipment and cardboard boxes, and then carried them inside the Morgenson family home.

    What took place over the next eight weeks was inspired by a Hollywood movie called The Joneses about a family of marketers who move into a local neighborhood to sell their products secretly to their neighbors. The idea was to test the power of word-of-mouth marketing. By filming a 'rear' family in unscripted (无剧本的) situations, my team and I would document how the Morgensons' circle of friends responded to brands and products the Morgensons bought into their lives.

    With the help of 35 video cameras and 25 microphones hidden inside the furniture, the operation done secretly showed something shocking. The most powerful hidden persuader of all isn't in your TV or on the shelves of your supermarket. It's a far more important influence that's around you almost every waking moment: your very own friends and neighbors. There is nothing quite so persuasive as observing someone we respect or admire using a brand or product.

    Our analysis also found that the brands the Morgensons used went faster. About one third of the Morgensons' friends began promoting these same brands to their friends. We also found that the brands their friends were most likely to buy at the Morgensons' suggestion were the bigger and better-known ones. This proved my thoughts that traditional marketing and secret marketing work well together. The most persuasive advertising strategies are strengthened by word-of-mouth advertising.

    Whenever I meet with company managers, I tell them that the people who hold the real marketing power are mouse-clicking consumers and their wide circles of real-life friends. In other words, the people who hold the real power are us.

    Artificial intelligence keeps defeating human, it is making countless victories against human in different fields of life and trying to push human to the corner.

    Google's DeepMind has defeated the world's number one player Ke Jie. Human brain somehow has been replaced by a machine and scientists are working very hard on developing a human brain by implanting a chip and connecting it to the thick neuron that connects the two hemispheres of the brain. Well, who doesn't want to get his brain upgraded to be as smart as the brain of Albert Einstein or Charles Darwin?

    Humans will probably one day invent a brain that can be implanted in the human skull and reprogram all the human thoughts, but this invention doesn't seems to be happening in the foreseeable future since human brain took millions of years to evolve. Some scientists believe that human will defeat death in the next twenty hundred years but they can't really predict how long it's going to take to develop a human brain that can completely replace the natural brain.

    Despite of this accomplishment in the field of artificial intelligence, it couldn't crease people from believing that science can't stand alone. For instance, AI can imitate human brain and most of the time outperforms it, but there are still a lot of hidden secrets. AI outsmarted Ke Jie has consciousness unlike the AI, Ke Jie felt sad when he was defeated and buried his face in his hands but the AI didn't feel happy and celebrate his victory.

    The computer of 1960 is the same as the computer of 2017 in terms of consciousness, there is no signs so far telling us that there is an algorithm(运算)that can make a conscious computer and decipher (译解) its feelings. We can predict what the future will look like according to the past, especially from scientific point of view but the development of human brain seems unpredictable and unknown.

    There are many reasons why I encourage people to travel, and I know that the experience will make one a better person.

    I remember when I was travelling I began to know the world better. The world is not just about me, my small town and home. Although you will meet different people from all over the world, you will realize that people are similar in their dreams, hopes and feelings. Enjoy exploring the different cultures, and you will also find that people are different in some of the things they do and how they live. Once you understand their ways, it need not be strange or scary. Often we read stories about other cultures in books. Only when we visit their areas do we find that those stories are something wrong.

    One thing you may find out is that there are problems all over the world. We can't just get money to send to these areas and hope that will work them out. The world should get involved（干预）and help wherever there are problems. People everywhere should be given a chance. It is so easy to ignore this if one does not travel and explore. One can look around and see that so many people have many challenges worse than ours. One can realize that sometimes our biggest problems are not that big after all.

    On your journey you will meet lots of new friends. Talking to strangers and finding about their lives is a great way to spend your time. you will certainly be more confident after having to cope with problems and make many decisions along the way.

    When you travel, you have to be on your own in some situations. You will surprise yourself by how well you can do that. All your special experiences could make an interesting book to read. It would be filled with all your adventures and special memories.

    Traveling around and seeing so much happening in the world around us is a wonderful experience. If we could all just travel a little more and share our experiences, we would all be better people and the world would be a better place.

    She will face the challenges of riding a bike to school or not being able to climb the monkey bars during playtime. But little Ella Peggie, who was born without her left arm, will get an extraordinary opportunity to share a life-changing bond with her new beloved pet, three-legged puppy.

    When her mother, Brooke Hodgson, saw the one-year-old puppy named Snowy, she knew instantly it would be the perfect companion for her one-year-old daughter. “My heart skipped a beat when I saw Snowy online, ”Ms. Hodgson said. It took just three days for the puppy, who recently had surgery to remove a 1eg, to find a new home after she was sent to the animal shelter last week.

    “I knew she was going to be perfect for Ella—they share the same age so they both have a long life of friendship ahead of them. I just know that Snowy is going to increase her confidence when she is growing up. It's going to be great for Ella when she realizes she's different or when she's having a bad day, she will see the resemblance and know that she's not alone. ”

    Ms. Hodgson has been touched by the relationship between the pair since the lively puppy became the latest addition to the family. And she believes the caring puppy will be by Ella's side through the highs and lows of her life. Ms. Hodgson said, “Every morning Snowy looks for Ella first before she runs to anyone else. It's quite a unique link. I'm just thankful that I was able to give her this dog. I just can't wait for them to get even closer. Not many people are able to do this for their children so we're very lucky to have Snowy. I can't even explain how I feel fight now. ”The young mother said Snowy, who was welcomed into the family just a week ago, has been playing a very special part to Ella's life as well as her three-year-old brother Blake and her father, Stewart Peggie.
