New research shows that the healthy brain may hold memories which we don't even remember. In The Journal of Neuroscience, experts report that the brain might hold more memories than people realize, but that restoring those memories can be tricky. Memory Check First, participants saw a list of 120 real words mixed with 80 nonsense words. Next, they saw another word list and tried to remember which words had been on the first list. Meanwhile, their brains were scanned with functional magnetic resonance imaging. While participants reviewed the second word list, their brain scans showed more activity in a certain brain area -- the posterior median temporal lobe -- when they saw words that had been on the first word list. But participants didn't always remember that they'd seen those words before. Sometimes, they _ and said they hadn't seen those words before. In other words, the posterior median temporal lobe was more sensitive to memory than participants' consciousness, the researchers note. "Album"of Memories Another part of the median temporal lobe also attracted the scientists' attention. The anterior median temporal lobe showed more activity when participants thought they were seeing a new word, the study shows. So, why did participants sometimes mess up their memory recall? It might be that two parts of their brain -- the posterior and anterior median temporal lobes -- might be dueling for the upper hand in deciding what actually happened in the past, the study notes. In other words, memories might have a photo album in the brain, but sometimes we forget what's on all of the photo album's pages. What did the experts discover when the participants saw the words on the first word list appear on the second word list? A) The instrument worked faster. B) The participants were more conscious. C) The posterior median temporal lobe was more active. D) The anterior median temporal lobe was more active.

For Canadians, backpacking Europe is a special ceremony signifying a new life stage. Unlike package tours, backpacking is a struggle, full of discovery and chance connections. It is about focusing on something different from our own lives and losing ourselves in a new world, if only for a moment. Well, that's what backpacking Europe is supposed to do. That's what it used to do before modern communications, social media, and commercial hostelling . Older Canadians would not recognize the Europe that they backpacked in the 1960s, 1970s and even the 1980s. Far from a rough adventure into foreign cultures, the European experience has been _ in part by today's technology. A few years ago, I took my then 60-year-old father on a backpacking trip across part of Europe and Turkey. As he is an experienced traveler and someone who possesses a strong sense of adventure, I decided that we'd travel on a budget, staying in hostel dorms. For him, backpacking through Europe in 1969 was about independence and struggle. But two things surprised him at the end of our journey. First was how technology-based backpacking had become: Young people were so directly connected to home that they were hardly away in any meaningful sense. Second, the lack of connections we made with locals. Instead of making us feel closer to a place, he found commercial hostelling actually made us more alienated . But there was some room for hope. While technology takes our attention away from the beauty and history before us, there were also ways in which it helped us to connect with our surroundings. Websites like Airbnb have made it easier to stay with enthusiastic locals. Couch Surfing helps organize meet-ups between locals and travelers. The online marketplace Dopios offers a chance to meet locals through enjoyable experiences like a personalized city tour. Backpacking can never be the way it was for our parents' generation. But doing a little study of history and culture before leaving, and bravely getting rid of any electronic devices while... What's the author's attitude towards technology? A) Negative. B) Objective. C) Uncertain. D) Uninterested.

Q: Loma just had to get in touch with someone:"I had to tell my best friend something important. I tried calling her but I couldn't get through. So I sent her an e-mail and then I spoke to her on MSN. Without technology I would not have been able to tell her. " Staying connected with friends and family is important for us.

Almost 30%said they'd be completely out of their friends without their cell-phones and other methods of communication. What do they do when they've got news they need to share now? Most teens say they try to reach their friends by phone. But if they don't reach them, they use QQ, e-mails, and text messaging to _ Lots of people use one way of communication--like text messaging--to get a friend's attention and then use another where they can talk more. "My friends and I always tell each other everything that happens. So I send them text messages to tell them to come online so we can talk about it," said Sabeiha. "When planning to get together with friends", Julian said, "the easiest and fastest way I know is to send a text message to my contact group." Jocelyn said. "If I want to go to see a movie with a few friends, I usually send text message to them. By telephone, you have to call every single friend one by one.
