As I enter my 40s, I've noticed many of my parents' generation think social networking is something they are simply unable to understand. They fear that, should they try, they will somehow get it wrong; they will say the wrong thing, do the wrong thing or behave in a way that causes embarrassment(尴尬). But here's the first secret of social media: Everyone feels this way.

    I recently met a young actor who was complaining that her work demands that she join Microblog, but she always feels like she doesn't have anything smart to say. It's the same resistance (抵制)I hear from the older generation, who, however, have somehow believed that age is the barrier(障碍), rather than the differences of personal taste.

    Here's the second secret of social media: everybody uses it for more or less the same reasons. Older generations often sign up to stay in touch with children and relatives. We talk about this kind of communication like it's some old-fashioned activity, but it is exactly why younger people use social media. The truth is that most people use social media to gently keep an eye on one another, to see how those they care about are doing without needing to ring them up on the phone every night.

    And this is the last secret of social media: everyone gets to use them in their own way. Newcomers—younger and older—who worry about “getting it right” are thinking that there's a right way to get them. But actually there isn't. Personally, I talk a lot on Microblog. And some people post nothing and they use social media every day as readers. Social media companies would rather see people decorating their networks with pictures and posts, but there's no rule against being a fly on the wall. It's also a fine way to get involved.

    We're quick to forget that the web wasn't invented by 13-year-olds; it was created by today's seniors. I'd never try forcing those with no interest in social networks to use Microblog. But don't let the talk of age divides put you off. There's nothing to stop the older generation from joining in the network their own generation created.

Lisa: My best teacher is my geography teacher in 10th grade. Why? Because we did school projects! Back then I wrote about India and never forgot what I had learned. He brought the culture to life by letting me become part of it. He also listened to us and was always ready with a kind word.

David: My best teacher is my high school social studies and history teacher, Thomas Ladenburg. He respected us, though we were just teenagers. His class was never boring because he often asked us to discuss in class. He used his own materials which made the class very interesting.

Henry: My best ever teacher is my biology teacher in high school. I really liked her class. She explained everything very clearly. She also checked our notebooks to make sure we had written down what she said. Now, many years later, I can still remember a large part of the things she taught!

Susan: The best teacher I have ever had is my 10th grade social studies teacher. She was always in a good mood and kept us laughing. She was really young, so she acted like us teenagers, which made learning fun. If we needed to talk to an adult about a problem, we would always come to her because we knew she could help us.

Tom: My favourite teacher is Mr. Yelle. He taught us math, science and music. He spoke to us “at eye level”, and was very patient and kind. We did great projects for the science fairs. Forty years later, I still remember his lessons very well. By the way, though he was called Mr Yelle, he didn't yell(喊叫).

    Once an old man rose early to read each morning. His grandson wanted to be just like his grandfather, so tried to emulate him every way he could.

    One day the grandson asked, “Grandpa, I try to read just like you do, but I don't understand most of it, and I forget whatever I do understand immediately I close the book. So what good is it for me to read?”

    The grandfather, who was putting coal on the fire, said, “Take this coal basket down to the river and bring me back a basket of water.”

    The boy did as told to, but the water leaked out before he could get the basket home.

    The grandfather laughed, saying, “You'll have to move a little faster.” This time he ran faster, but again the basket emptied. Out of breath, he decided it was impossible to carry water in a basket, and he went to get a bucket（桶）. But the grandfather said, “I want a basket of water instead of a bucket of water. You're just not trying hard enough.”

    The boy knew what he was trying to accomplish was impossible. However, he decided to show his grandfather a third time.

    The boy dipped the basket into the river and ran as hard as he could. With the empty basket, he gasped（喘气说）, “See Grandpa? It's useless!”

    “So you think it useless?” the old man asked. “Then look at the basket.” To his surprise, the boy found it washed clean of the dirty coal stains and now clean inside and out.

    “My child, that's what happens when you read the book. You might not understand or remember everything, but the words will change you inside and out. That is the work of reading in our lives.”

    US people are overweight, eat lots of fast food and fill their homes with pets. At least that's what 21 European teenagers think.

    The students, 18 from Germany and 3 from France, are exchange students. They are studying in the US for a year. After a few days in the US, they said what they thought about the country.

    Most talked about the amount of fast food US people eat. It's not that the students don't eat fast food. They just don't eat as much.

    Laetitia Villeneuve from France said she eats fast food, usually McDonald's, only once or twice a year.

    "I like it," said Nora Koeberle from Germany. "But I couldn't eat it every day. I'd get fat. "

    Students are surprised at how big US people seem.

    "There are fat people in Germany," said Antonia Greimel from Germany. "But not as many as there are here."

    They also spoke about the animals. Silvana Wolfram from Germany said she had heard about how people had lots of pets in the US.

    Other ways of US high schools interested the students.

    For example, Koeberle said she wouldn't be able to play an instrument or sports as part of her classes in Germany. She can in the US.

    But the best thing about US high schools is something the European kids can't get back home. "I do wish we had parties," Koeberle said.

    It was hard to accept, but the sad day had finally arrived. I still remember the tears welling up in my six-year-old sister's eyes as she looked around the empty closet in wonder. The space once filled with her clothes now held only loneliness and sorrow. This little child had come to the realization that her father was gone. He had left us, and there was simply no way to change it.

    Being the oldest of four girls has never been easy, but with the departure of our father, our world and dreams were broken beyond repair. My mother, the most amazingly warm-hearted person in the world, has worked harder than anyone should simply to mend our broken household. However, long hours at work often prevented her from physically being there in our times of need. This is where I have stepped up as the temporary caretaker of my three small sisters.

    Many students write college essays about their leadership positions in school and the community but I feel that my greatest accomplishment is the role I have played within my own family.

    Senior year in high school is not simple for anyone, especially when it feels like the entire world is resting on your shoulders, but this is how I have felt for the past two years, I have continually tried to fulfill the dream my mother holds for my future. My mother was not able to complete her college education, and so this success is her top significance for her children.

    A leader is defined as one who has influence on others. I hope that my leadership affects the lives of my sisters and everyone around me. In dedicating myself to my family and school, I have set goals that I will do anything to accomplish. I am an extremely determined individual, and my university will help me take the next step in climbing the ladder of success.

    Like any new ninth-grader on the first day of school, Joemar Class had ninth-grader- emotion (情绪). He's not used to school in Hartford. He's used to going to school in his home town of Florida, used to seeing his friends, used to having class in Spanish.

    "Nervioso," he said in Spanish.

    We first met Joemar in mid-October in the San Juan Airport. His father, Guillermo Class, had sold his car to buy plane tickets to get his kids and fly them up from Puerto Rico. The island was almost destroyed (毁坏) by the deadly storm—Hurricane Maria.

    Now, they are settling into their new home in Hartford's South End. A week later, and, using his wife's car, Class drove 16-year-old Joemar to his first day at Bulkeley High School. After a short ride, he got out in front of his new school. Inside, he met Gretchen Levitz—the school's program director.

    "I see you have new uniform (校服)," Levitz said. "You look great. Are you ready for a good first day?"

    Then he met couple of teachers.

     "Hello," they each said in Spanish. They asked where he's from, and told him they were happy to see him. Then Levitz took him on a quick tour of the school before classes began—to her office the school store, the library, and the dining hall.

    A total of 19 languages are spoken in Bulkeley High School. "We have so many new students coming here from other countries every single day," Levitz said. "So it's not like he's the only one who has that feeling."

    "You could tell he's little worried," Guillermo said as we left." But, at the same time, he's looking forward to it."
