More over smart phone, the intelligent watch is about to take your spot as the latest hi­tech current, allowing wearers to glance at messages and even take calls without touching their phones. The i'm Watch, available since 2011, is the flagship product of an Italian company—i'm. This smart watch is an assist to the smart phone, with which it can communicate by Bluetooth wireless technology. It means you can leave your phone in your pocket as you answer or reject a call, review e­mails or read updates from friends on Twitter or Facebook.

    The i'm Watch also has its own applications, such as i'm Sport, which links with a heart rate detector (检测器) to allow a runner to check his pulse. Such functions already exist in specialized sports watches but not on watches that are linked to smart phones.

    With a square shape, a 3.8­centimeter touch screen and various colors, the i'm Watch sells for a minimum of 300 Euros ($390) for the basic model and prices climb to 16 000 Euros for a luxury model in silver or decorated with diamonds.

    So far, the watch has already found 30 000 buyers, 80 percent of whom are men aged 25 to 50. “Seventy percent are iPhone users, 25 percent Samsung and the rest are other telephones using Google's Android operating system，” said Massimiliano Bertolini, a manager of the company, which aims to sell more than 200 000 watches this year. The company's target market is the person who is always glued to his smart phone, even in meetings or at the movies, or people who wish to keep an eye on their heartbeat during exercise. They will especially target women with advertisements emphasizing its design rather than its technology.

    New research has found that even if you give up smoking,the damage it has done to your genes（基因）will stay there for a much longer time.

    In the research,a team of US scientists studied the blood of 16,000 people.Among them,some were smokers,some used to smoke,and the rest were non-smokers.Scientists compared their genes and found that more than 7,000 genes of smokers had changed-a number that is one-third of known human genes.

    According to NBC News,both heart disease and cancer are caused by genetic changes.Some people may have had the changes when they were born,but most people get them in their day-to-day lives while doing things like  smoking.

When you stop smoking,a lot of these genes will return to normal within five years.This means your body is trying to heal（治愈）itself of the harmful effects of smoking.But the changes in some of the genes stay for longer.They can stay for as long as 30 years.It's almost like leaving a footprint on wet cement（水泥）一it will always be there, even when you've walked away and when the cement becomes dry.

    Although the study results may make people unhappy,there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer ricks.

    Ask any kid, and you'll likely hear that time spent with friends is the coolest and most important part of the school day. Educators, as well, acknowledge that making friends is one of the most valuable things children do as they learn and grow. But many parents are perplexed by their children's social lives, wondering how to help their kids cope with the challenges, heartbreaks, and the joys of making friends, losing them, and making friends again.

    “Friendships help children gradually learn to be independent, contributing members of a community and it's just as important as their academic growth” notes Diane Levin, Ph.D., author of “Remote Control Childhood.” However, it's a slow process. There are many social skills to learn, which advance with age and experience, trial and error, and experiencing the satisfaction that comes from contributing to an ongoing friendship.”

    “Friendship starts as soon as children can crawl off their parents' laps over to another child,” adds Michael Thompson, Ph.D., co-author of her life with you to her life with her friends. but who their friends are, how they interact with them, and how popular they are, is something parents have only limited control over.”

    Experts on children's behavior say that problems like jealousies, breakups, bullying and teasing account for a big part of what parents, kids and teachers talk about, and what parents worry about.

    Get insights into how children's friendships develop and how parents can help, if needed, and find ways to determine if your child is at risk for serious social problems or simply suffering from real (but common) social challenges.

    Jack threw some papers on my desk and looked at me angrily. “What's wrong?” I asked. “Next time you want to change anything, ask me first,” he shouted and left.

    “How dare he treat me like that?” I thought. I had just changed one long sentence, and correct grammar—something I thought I was paid to do. In fact I had been warned. On the first day one of  my workmates took me aside and reminded me of his temper. As the weeks went by, I came to look down on Jack.

    One day Jack's other papers left me in tears so I stormed into his office angrily. “What?” he asked.

    Suddenly I knew what I must do. After all, he earned it. “Jack, the way you've been treating me is wrong. I've never had anyone speak to me that way. As a professional, it's wrong for me to allow it to continue,” I said. Jack smiled nervously, “Susan, I make you a promise that I will be a friend. I will treat you as you should be treated, with respect and kindness,” he said. With these words, I left.

    Jack avoided me the rest of the week, and never questioned my work again. I brought cookies to the office one day and left some on his desk. Another day I left a note: “Hope your day is going great.” Over the next few weeks, Jack reappeared , but there were no more Jack's papers. One year later I discovered I had breast cancer, and was scared. The statistics (统计数字) were not great for my long-term survival.

    On the last day of my hospital stay, Jack came and silently handed me a bundle with several bulbs inside. “Tulips (郁金香) ,” he said. I smiled, not understanding. He cleared his throat. “If you plant them when you get home, they'll come up next spring. I think you will be there to see them when they come up.” Tears clouded my eyes and I whispered: “Thank you.”Jack held my hands firmly, saying, “You are welcome. You can't see it now, but next spring you will see the colors I picked out for you.”

    I have seen those red and white striped（有条纹的） tulips push through the soil every spring for over ten years now. This past September the doctor declared me cured. At a moment when I was praying for just the right word, a man with very few words said all the right things. After all, that's what friends do.

    Mr. White was born in a small village. His parents worked hard on their farm but they couldn't get enough food for the family. Of course, he couldn't be sent to school and his uncle who worked in a school taught him at home. And he learned a lot before he left there. When he was sixteen, he found work in a factory. As an abled worker, the boss liked him and seven years later the boss married his daughter to him and with his help, Mr White had his own factory after another seven years passed.

    Mrs. White liked her husband very much. So she was always afraid he loved the other women. She often asked him a lot of questions. He wouldn't make her angry and was more careful.

    One evening Mr. White was very busy and he told his secretary to help him. When they finished the work, it was ten in the evening. He had to see her home. That night his wife felt unwell and told him to take her to a hospital. He helped her to get on the car and started. But soon after that he found there was a shoe in the car. He had a look at his wife. The woman seemed to be asleep. He picked it up gently and threw it out of the window.

    Soon they got to the hospital. As he was going to help her to get off, suddenly the woman called out, “Where's my shoe?”

    Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity（长寿）? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

    The study shows that those living the longest are more outgoing, more active and less neurotic (神经质的) than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times. Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.

    Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.

    Unfortunately, another recent study shows that your mother's personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we're adults, which may mean that kids of depressed moms end up dying younger. Personality isn't destiny, and everyone knows that individuals can learn to change. But both studies show that long life isn't just a matter of your physical health but of your mental health.
