“Did you hear what happened to Adam Last Friday?” Lindsey whispers to Tori.

       With her eyes shining,tori brags，“You bet I did, Sean told me two days ago.”

Who are Lindsey and Tori talking about? It just happened to be yours truly, Adam Freedom, I can tell you that what that what they are saying is (a) not nice and (b) not even true. Still, Lindsey and Tori aren't very different from most students here at Linton High School, including me. Many of our conversations are gossip(闲话)。I have noticed three effects of gossip: it can hurt people, it can give gossipers a strange kind of satisfaction, and it can cause social pressures in a group.

An important negative effect of gossip is that it can hurt the person being talked about. Usually, gossip spreads information about a topic-breakups, trouble at home, even dropping out-that a person would rather keep secret. The more embarrassing or shameful the secret is, the juicier the gossip it makes. Probably the worst type of gossip is the absolute lie. People often think of gossipers as harmless, but cruel lies can cause pain.

If we know that gossip can be harmful, then why do so many of us do it? That answer lies in another effect of gossip: the satisfaction it gives us. Sharing the latest rumor(传言)can make a person feel important because he or she knows something that others don't. Similarly, hearing the latest rumor can make a person feel like part of the “in group.” In other words, gossip is satisfying because it gives people a sense of belonging or even superiority(优越感).

Gossip also can have a third effect: it strengthens unwritten, unspoken rules about how people should act. Professor David Wilson explains that gossip is important in policing behaviors in a group. Translated into high school terms, this means that if everybody you hang around with is laughing at what John wore or what Jane said, then you can bet that wearing or saying something similar will get you the same kind of negative attention. The do's and don'ts conveyed through gossip will never show up in any student handbook.

   The effects of gossip vary depending on the situation. The next time you feel the urge to spread the latest news, thing about why you want to gossip and what effects your “juicy story” might have.

    The stories we share with one another are important. They show wisdom and provide inspiration. They are important to our development. But sometimes people choose not to tell.

    Consider the negative effects of not sharing a story in the news: People are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.

    There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, “The fact is that history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When they are finally uncorked, their power to destroy is set free.”

    There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret—especially those that embarrass someone else.

    Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.

    Honesty and openness is important: It proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard work, we do not have to be limited to our mistakes.

    Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in an appropriate manner.

    A few weeks ago, I called an Uber to take me to the Boston airport for a flight home for the holidays. As I slid into the back seat of the car, the warm intonations（语调）of the driver's accent washed over me in a familiar way.

    I learned that he was a recent West African immigrant with a few young children, working hard to provide for his family. I could relate: I am the daughter of two Ethiopian immigrants who made their share of sacrifices to ensure my success. I told him I was on a college break and headed home to visit my parents. That's how he found out I go to Harvard. An approving eye glinted（闪烁）at me in the rearview window, and quickly, we crossed the boundaries of rider and driver. I became his daughter, all grown up – the product of his sacrifice.

And then came the fateful question: "What do you study?" I answered "history and literature" and the pride in his voice faded, as I knew it might. I didn't even get to add "and African-American studies" before he cut in, his voice thick with disappointment. "All that work to get into Harvard, and you study history?"

    Here I was, his daughter, squandering the biggest opportunity of her life. He went on to deliver the age-old lecture that all immigrant kids know. We are to become doctors (or lawyers, if our parents are being generous) – to make money and send money back home. The unspoken demand, made across generations, which my Uber driver laid out plainly, is simple: Fulfill your role in the narrative（故事）of upward mobility so your children can do the same.

I used to feel anxious and backed into a corner by the questioning, but now as a junior in college, I'm grateful for their support more than anything. This holiday season, I've promised myself I won't get annoyed at their inquiries. I won't defensively respond with "but I plan to go to law school!" when I get unrequested advice. I'll just smile and nod, and enjoy the warmth of the occasion.

    The Board Meeting had come to an end. Bob started to stand up and pushed the table, spilling his coffee over his notes. “How embarrassing! I am getting so clumsy in my old age.”

    Everyone had a good laugh, and soon we were all telling stories of our most embarrassing moments. It came around to Frank who sat quietly listening to the others.

    Frank began,“My Dad was a fisherman. He worked hard and would stay out until he caught enough to feed the family. Not just enough for our family, but also for his Mom and Dad and the other kids that were still at home.”

    Frank's voice dropped a bit. “When the weather was bad he would drive me to school. He would pull right up in front, and it seemed like everybody would be standing around and watching. Then he would lean over and give me a big kiss on the cheek and tell me to be a good boy. It was so embarrassing for me. Here I was twelve years old, and my Dad would lean over and kiss me good-bye!”

    He paused and then went on, “I remember the day I thought I was too old for a good-bye kiss. When we got to the school, he had his usual big smile. He started to lean toward me, but I put my hand up and said, 'No, Dad.' It was the first time I had ever talked to him that way, and he had this surprised look on his face. I said, 'Dad, I'm too old for a good-bye kiss. I'm too old for any kind of kiss.' My Dad looked at me for the longest time, and his eyes started to tear. I had never seen him cry. He turned. 'You're right,' he said. 'You are a big boy ... a man. I won't kiss you anymore.'”

    For the moment, the tears began to well up in Frank's eyes. “It wasn't long after that when my Dad went to sea and never came back.”

    I looked at Frank and saw that tears were running down his cheeks. Frank spoke again.“Guys, you don't know what I would give to have my dad give me just one more kiss on the cheek.”

    A six-wheeled robot travels underground in Hefei to discover warning signs of faults inside the pipeline network, "It looks like a toy car at first, but it's much more complicated than that," said Xu Mao, the robot's operator.

    The pipeline robot, developed by Wuhan Easy-Sight Technology, is made up of four parts — crawler, camera, cable reel, and controller. A full charge can enable the robot to work for four to five hours, covering a distance between 800 and 1,000 meters in the underground p ipeline.

    The robot made its appearance last month in Shushan District. It will carry out inspections of the underground pipeline network stretching 150 kilometers." Whether the pipe is leaking, damaged or blocked, we can clearly see its situation through high-definition(高清晰度的)cameras fixed into the robot, " said Qi Chuanshuai from the provincial construction engineering and testing institute.

    The real-time data including video images of the pipe will be up loaded and displayed on a computer. "If we find any problems, we stop the robot and record the flaws," Xu said. "We report the faults to local government, who will arrange the repair as soon as possible."

    With the rapid develop merit of cities, it is becoming increasingly difficult to manage underground pipelines. Among all the difficulties, discovering faults in the sewage (污水)and rainwater pipelines comes first. Many other cities such as Wuhan, Nanjing, Shenzhen, and Shanghai are using the robots to inspect their pipelines, the robot's developer said.

    Equipped with environmental detection sensors, the robots can monitor temperature and damp, poisonous gases, oxygen levels and smoke density, while providing color diagram in real time. "Compared with human workers, robots are able to enter smaller pipes and are immune (有免疫力的)to poisonous gases in sewage pipes," said Ge Shengli from Shushan District' s city management company." No digging is required and there is no need to interrupt traffic," Ge added.
