When I was 8 years old, I decided to run away from home after a quarrel with my mother. With my suitcase packed and some sandwiches in a bag, I started for the front door.

     My mom asked where I was going. “I'm leaving home,” I said.

     “What's that you're carrying?” she asked.

     “Some clothes and food,” I replied.

     “If you want to run away, that's all right,” she said. “But you came into this home without anything and you can leave the same way.”

     I threw my suitcase and sandwiches on the floor and started for the door again.

     “Wait a minute,” Mom said. “You didn't have any clothes on when you arrived, and I want them back.”

 This infuriated me. I tore my clothes off — shoes, socks, underwear and all — and shouted, “Can I go now?”

     “Yes,” my mom answered, “but once you close that door, don't expect to come back.”

     I was so angry that I shut the door forcefully and stepped out of my home. Then I noticed down the street two neighbor girls walking toward our house. I was so shy that I saw the big spruce (云杉) tree in our yard and jumped under the low-hanging branches. A pile of dried-up brown needles were beneath the tree, and you can't imagine the pain those sharp needles caused to my body.

     After I was sure the girls had passed by, I ran to the front door and knocked at it loudly.

     “It's Billy! Let me in!”

     The voice behind the door answered, “Billy doesn't live here anymore. He ran away from home.”

     Looking behind me to see if anyone else was coming down the street, I said, “Mom! I'm sorry. I'm still your son. Let me in!”

     The door opened and Mom's smiling face appeared. “Did you change your mind about running away?” she asked.

     “What's for supper?” I smiled back.

    A European Union program is letting blind people experience famous paintings for the first time. It uses three dimensional(3-D) printing to re-create famous paintings so they can be touched.

    One painting printed with the new technology is Gustav Klimt's “The Kiss.” It is a popular attraction at the Belvedere Museum in Vienna, Austria. The painting shows a man and a woman standing in a field filled with flowers. They are wearing gold robes and have their arms around each other. The man leans down to kiss the woman.

    Klimt finished the painting in 1908. Until now, people who had trouble seeing could not appreciate the artwork. But thanks to the reproduction they can touch the piece and feel the ridges and depressions. Andreas Reichinger started making 3-D versions of artwork in 2010. He said this reproduction was his most difficult project because the couple's robes are so detailed.

    Dominika Raditsch is a blind museum visitor. She touched the reproduction. As she moved her hands around it she said, “Exactly, can you see these? There are so many details.” Raditsch said she can imagine what the original painting looks like when she touches the reproduction. “It's somehow round. You can feel it. You can feel it. It comes with it. And in many places it's so smooth. And then I think to myself: it probably shines too!” Raditsch said.

    The Belvedere is not the only museum to have 3-D versions of its artwork. Some of the pieces at the Prado, in Madrid, Spain, have reproductions that can be touched. But the piece in Vienna has one special part: It is made with widely available 3-D printing technology. That means one day, blind art fans anywhere in the world could download the source files and print the reproductions themselves.

    Some of us friends are making big decisions in their life: Which universities should they apply to? I also noticed that many high school students in China are thinking of studying at universities abroad. Unluckily, from what I've seen, the information given by some websites and other media about studying abroad is very limited and sometimes even wrong.

    There are once a Chinese girl who hoped that she could go to Columbia University in the US because she wanted to major in (主修)journalism. Columbia has a very famous graduate(研究生)program in journalism. However, they have no journalism program at the undergraduate(本科生)level! What's more in both Canada and the US, it's not suggested that students throw themselves into journalism right after high school. School say that students should take in more knowledge about the world and writing before entering that field.

    The University of Waterloo, a Canada university famous for its engineering program, is another example. The emphasis(重视)of engineering in this school may go beyond your expectations. According to our teachers, this university spent millions of dollars building a library just for engineering students. The school's computer science, mathematics and accounting are also great programs for students.

    But, to be honest, according to my friends who have visited this university, the campus and the food are not very nice. Maybe this is because the school stresses its academic(学术的)strengths too much, thereby paying little attention to personal comforts.

    Now you see, choosing a university is really not that easy. We need to do good research and consult as many people as possible before making a decision.

    How does a sunset work? We love to look at one, but Jolanda Blackwell wanted her eighth-graders to really think about it and question.

    So Blackwell had her students watch a video of a sunset as part of a physics lesson on motion. "I asked them: ' So what's moving And why' " Blackwell says. Some thought the sun was moving; others knew that a sunset is the result of the Earth spinning around on its axis. "Usually, my biggest challenge is trying to keep them patient," she says. "They just have so many burning questions."

    "Every day, we meet new information," says Charan Ranganath, a psychologist. Ranganath was curious to know why we keep some information and forget other things. So he got 19 volunteers and asked them to review more than 100 questions. When the participants' curiosity was aroused, the parts of' their brains that regulate pleasure and reward lit up. Curious minds also showed increased activity in the brain, which is involved in greater memories.

    "Curious brains are better at learning not only about the subject at hand but also dull information. This is a phenomenon teachers can use in the classroom," says Evie Malaia, a professor. "Say a kid wants to be an astronaut," she says. NL Well, how do you link that goal with learning multiplication tables(乘法表)" "A teacher may choose to ask her class an interesting word problem that involves space exploration," Malaia says. Students may remember the answer to the word problem, but they'll also remember how they found the answer through multiplication.

    What Ranganath wants to know most is why some people seem naturally more curious than others. Lots of factors, including stress, aging and certain drugs  affect dopamine(多巴胺) processing in the brain. "If we could figure these things out, we could help those who may just seem bored," Ranganath says.

    Blackwell says she doesn't have to deal with that problem too often. She says her students love exploring the mysterious unknowns in science: What happens when a car crashes. How do rainbows work "I tell my kids there's no dumb questions," Blackwell says. "That's science: asking questions and seeking answers."

    Do you know of anyone who uses the truth to deceive(欺骗)?When someone tells you something that is true, but leaves out important information that should be included, he can give you a false picture.

    For example, someone might say,“I just won a hundred dollars on the lottery(彩票).It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!”

    This guy's a winner, right? Maybe, maybe not. We then discover that he bought $200 worth of tickets, and only one was a winner. He's really a big loser!

    He didn't say anything that was false, but he left out important information on purpose. That's called a half-truth. Half-truths are not technically lies, but they are just as dishonest.

    Some politicians often use this trick. Let's say that during Governor Smith's last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents(对手) says,“During Governor Smith's term, the state lost one million jobs!”That's true. However, an honest statement would have been,“During Governor Smith's term ,the state had a net gain of two million jobs.”

    Advertisers will sometimes use half-truths. It's against the law to make false statements so they try to mislead you with the truth. An advertisement might say,“Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache.”It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.

    This kind of deception happens too often. It's a sad fact of life: Lies are lies, and sometimes the truth can lie as well.

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

    "Nervioso，"he said in Spanish.

    We first met Joemar in mid­October 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 16­year­old 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 a new uniform (校服)," Levitz said. "You look great. Are you ready for a good first day？"

    Then he met a 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 a little worried," Guillermo said as we left. "But, at the same time, he's looking forward to it."
