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.

    I had been following the yellowish-green markers for a “popular and easy” three-mile out-and-back hike. Immediately after the trailhead(山道的起点), the trail became very rocky and steep. But having read information about the hike, I knew within five minutes, I was supposed to reach the hike's first overlook.

    However, the overlook never arrived. Instead, I found myself lost in the woods. Pulling out my cellphone, I saw it read “no service”. I checked the last text message I'd sent to my mom. It read, “Conference ended…going for a small hike before my flight home this afternoon.” I put my phone away and kept moving and yelling, “Help! Is anybody out there?” Every so often, I'd stop to listen, but I never heard a reply.

    I got out my phone again. The battery was running out fast as it searched for a signal. I struggled to find a place where I could get service. When I did, I called my mom. It went through! In a shaky voice, I said, “Mom?” And then the call dropped. More than 1,500 miles away, my mom instantly knew something was wrong. She called the Denver Police Department and was directed to the US Forest Service.

    This was how I was introduced to John, an operator from the US Forest Service. Following John's instruction on the phone, I finally escaped from the woods. I breathed a sigh of relief. Then my phone rang, and it was John, making sure I was still going in the right direction. “By the way,” he said, “we've had your mother on hold this whole time. We know once you get down the mountain, you will absolutely want to give her a call.”

    On a recent afternoon, some 60 years after they graduated from grammar school, Kathleen Rys, 72, and her sister Lorraine O'Kelly, 70, sat down and had a meal with a classmate, Bruce Smit, 71 for the first time.

    In the 1950s, Lorraine and Kathleen Rys' family moved from Chicago to Monee. As new kids at Monee Elementary School, they soon found themselves on the outs with other students.

    "I would be with the other guys and see Kathleen walking down the hallway, her head down, holding her books, walking slowly. And all of us guys would be flat against the wall until she passed. Then we'd burst into laughter. How rude is that? It's just crazy." said Smit, a doctor whose wife, Tammy, organized the meeting.

    The women said none of the teachers cared about it. "We just kept it to ourselves. " Lorraine said.

    Over the years, Tammy Smit said, "Bruce would just start to cry at times. He'd wonder what happened to the sisters, if they landed OK." One day a few weeks ago, Tammy took to the internet and found Mary O'Kelly, Lorraine's daughter, and offered to set up a meeting. The idea of revisiting the pain was not well- received by Kathleen, who had never married, let alone gone on a date. It took some convincing, but Lorraine finally got Kathleen to agree to meet with Bruce.

    Bruce broke into tears. "I'm so ashamed, so embarrassed," he said. "But I'm so happy you're still here and that I can finally apologize. " He said he hopes his apology will encourage others to seek forgiveness for the pain they make on others. Lorraine said, "This is a beautiful thing. It's just wonderful that a person from 60 years ago can ask for forgiveness. It's like a miracle to us. It's a healing to us."

    What makes a person a giver or taker? The idea "give vs. take" takes shape in all interactions (互动) and relationships of our lives. We're either giving advice, making time for people, or we're on the receiving end. We keep changing between the two based on different situations on a daily basis, if not an hourly one.

    According to Adam Grant, a professor at the University of Pennsylvania, most people are matchers. They make careful observations on takers and make it a point for them to pay something back. They hate to see people who act so generously towards others not receive any rewards. Actually, most matchers will try hard to promote and support givers so that they can get the good they deserve.

    Is there a gender factor (性别因素) that plays a part in this?

    A study led by Hannah Riley Bowles, a professor at Harvard University, focused on this question. She asked 200 senior managers to sit down in pairs where one person would act as the boss and the other as an employee to discuss salary promotions. Male "employees" asked for an average salary of $146k while the females asked for only $141k. But why did they not bargain as hard as the men? Simply because they were more likely to be givers.

    As a woman, I do enjoy the act of giving up my time, my knowledge, and my care and my attention to others. I don't expect anything in return, but I do tend to pull myself away when I feel like I'm being taken for granted. I also tend to get upset when I see a loved one's continuous actions of kindness go unnoticed. So, it's safe to say I'm 50% giver, 35% matcher and 15% taker.

    I do know someone, however, who is 99% giver. They're constantly devoting their time, sharing valuable insights (洞察力) and going out of their way for everyone who crosses their path. Although they're changed the lives of many people, they rarely see any of it returned. But the universe is slowly repaying them; they're now extremely successful, well known for what they do.

    Humans are social animals. They live in groups all over the world. As these groups of people live apart from other groups, over the years and centuries they develop their own habits and ideas, which are different from other cultures. One important particular side of every culture is how its people deal with time.

    Time is not very important in nonindustrial societies. The Nuer people of East Africa, for example, do not even have a word TIME that is in agreement with the abstract thing we call time. The daily lives of the people of such nonindustrial societies are likely to be patterned around their physical needs and natural events rather than around a time schedule(时间表)based on the clock. They cook and eat when they are hungry and sleep when the sun goes down. They plant crops during the growing seasons and harvest them when the crops are ripe. They measure time not by a clock or calendar(日历), but by saying that an event takes place before or after some other event Frequently such a society measures days in terms of "sleeps" or longer periods in terms of "moons." Some cultures, such as the Eskimos of Greenland measure seasons according to the migration of certain animals.

    Some cultures which do not have a written language or keep written records have developed interesting ways of "telling time". For example, when several Australian aborigines want to plan an event for a future time, one of them places a stone on a cliff or in a tree. Each day the angle of the sun changes slightly. In a few days, the rays of the sun strike the stone in a certain way. When this happens, the people see that the agreed-upon time has arrived and the event can take place.

    In contrast(成对比), exactly correct measurement of time is very important in modern, industrialized societies. This is because industrialized societies require the helpful efforts of many people in order to work. For a factory to work efficiently(well, quickly and without waste), for example, all of the workers must work at the same time. Therefore, they must know what time to start work in the morning and what time they may go home in the afternoon. Passengers must know the exact time that an airplane will arrive or depart. Students and teachers need to know when a class starts and ends. Stores must open on time in order to serve their customers. Complicated(复杂的)societies need clocks and calendars. Thus, we can see that if each person worked according to his or her own schedule, a complicated society could hardly work at all.
