My parents were in a huge argument, and I was really upset about it. I didn't know who I should talk with about how I was feeling. So I asked Mom to allow me to stay the night at my best friend's house. Though I knew I wouldn't tell her about my parents' situation, I was looking forward to getting out of the house. I was in the middle of packing up my things when suddenly the power went out in the neighborhood. Mom came to tell me that I should stay with my grandpa until the power came back on.

    I was really disappointed because I felt that we did not have much to talk about. But I knew he would be frightened alone in the dark. I went to his room and told him that I'd stay with him until the power was restored. He was quite happy and said, “Great opportunity.”

    “What is it?” I asked.

    “To talk, you and I” he said. “To hold a private little meeting about what we're going to do with your mom and dad, and what we're going to do with ourselves now that we're in the situation we are in.”

    “But we can't do anything about it. Grandpa,” I said, surprised that here was someone with whom I could share my feelings and someone who was in the same “boat” as I was.

    And that's how the most unbelievable friendship between my grandfather and me started. Sitting in the dark, we talked about our feelings and fears of life — from how fast things change to how they sometimes don't change fast enough. That night, because the power went out, I found a new friend, with whom I could safely talk about all my fears and pains, whatever they may be. Suddenly, the lights all came back on. “Well,” he said, “I guess that means you'll want to go now. I really like our talk. I hope the power will go out every few nights!”

    As kids, my friends and I spent a lot of time out in the woods,"The woods" was our part-time address, destination,purpose,and excuse.If I went to a friend's house and found him not at home,his mother might say, "Oh,he's out in the woods,"with a tone of airy acceptance.It's similar to the tone people sometimes use nowadays to tell me that someone I'm looking for is on the golf course or at the gym,or even "away from his desk."For us ten-year-olds,"being out in the woods" was just an excuse to do whatever we feel like for a while.

    We sometimes told ourselves that what we were doing in the woods was exploring.Exploring was a more popular idea back then than it is today.History seemed to be mostly about explorers.Our explorations,though,seemed to have less system than the historic kind: something usually came up along the way.Say we stayed in the woods, throwing rocks,shooting frogs,picking blackberries,digging in what we were briefly persuaded was an Italian burial mound.

    Often we got "lost" and had to climb a tree to find out where we were.If you read a story in which someone does that successfully,be skeptical: the topmost branches are usually too skinny to hold weight,and we could never climb high enough to see anything except other trees.There were four or five trees that we visited regularly—tall beeches,easy to climb and comfortable to sit in.

    It was in a tree,too,that our days of fooling around in the woods came to an end.By then some of us had reached seventh grade and had begun the rough ride of adolescence.In March,the month when we usually took to the woods again after winter,two friends and I set out to go exploring.We climbed a tree,and all of a sudden it occurred to all three of us at the same time that we really were rather big to be up in a tree.Soon there would be the spring dances on Friday evenings in the high school cafeteria.

    In the home country, a common language gives you the ability to communicate easily with the people around you; and you learn something about your country's history, people's habits, likes and dislikes, customs and traditions. This understanding influences your own behavior, and what you expect of others.

    Living abroad, it doesn't take long to realize that many things don't "work" the same, especially when moving from "the West" to "the East". Besides a different language, each country has its own social system and laws and ways of solving problems. You will find some of them strange and alien. Sometimes you may feel uncomfortable because you realize that things are not the same as you think they are supposed to be. This is what has become known as "Culture Shock".

    Living in an environment with an unfamiliar(不熟悉的)culture can cause stress, anxiety or worse- mental or physical illness in some cases. Culture shock is the shock of experiencing an unknown or new culture. Cross-culture Adjustment is the period of anxiety, great pain and confusion suffered when entering a new culture. It can have effects on a person's emotions and behavior. You should learn to accept and try to be used to different situations. One thing is certain: it is far easier to accept the new order of things than to try to change it.

    Most Asian people can bear foreigners and accept their strange habits and behavior, not only because it might be to their benefit but out of natural politeness and restraint(克制)in front of others. Westerners should not make use of this. They must try to accept and obey local rules and rules of behavior.

    When my vision-challenged daughter was 3, and I was pregnant with my second child, we got her glasses. It was a long process involving many different opticians (配镜师)over the course of a year, because of my daughter's overwhelming desire to scream and fly into a temper any time we tried to have her eyes examined. The fourth optician was amazing while my daughter didn't cooperate, she performed various miracles and managed what she called a “best guess” at her prescription.

    “Start with this,” she said. “When she realizes she can see better, bring her back, and we can try for something more accurate.”

    I didn't want to pay $300 for glasses that might be replaced in a month's time, so I decided to bring her straight to a Walmart optical. Things were going on well, until the optician needed to take an additional measurement, which would involve holding a ruler up to her eyes and measuring the distance between the outer corner of one eye and the inner corner of the other.

    “Are you sure you need the measurement?” I asked. “She's really not cooperative when it comes to the eye-testing stuff.”

    “We definitely need to have it, we can't fill her prescription without it.” the optician said.

    But my daughter would not let the optician anywhere near her face with the small plastic ruler. She started yelling and crying, and we took her off to the side and promised we'd get ice cream afterward if she let the nice lady hold the ruler near her nose! The optician gave us the ruler, thinking we would have an easier time, but when my daughter knew we needed to hold the ruler near her face, which, in toddler logic, meant a life-or-death situation, she prevented us from getting anywhere near her.

    Finally, my husband and I agreed that one of us would have to hold her down and the other would take the measurement. I sat on the floor trying to hold her head still while my husband tried to get an accurate reading on that stupid ruler. Despite her struggle and scream, we finally got it. My daughter stopped crying three seconds later and went back to play as if nothing had happened.

    There is no version of this story where I feel comfortable us even if it was for her own good. I felt awful wondering, if magically know what to say to get her cooperation? The weeks spent with a special book about wearing glasses, telling her how great glasses were... I could feel tears welling up and I thought, “I can't cry. I'm sitting on the floor of a Walmart optical centre. I can't cry here.”

    And there it was the final thing I could not bear. It w already reduced me to sitting on the floor of a Walmart optical p toddler down to press a ruler against her face and do it for the packed Saturday audience of all the Walmart checkout counters. I cried. Big, shoulder-shaking sobs. Sitting right there on the floor of a Walmart, behind the optical counter.

    Five days later, the Walmart optical centre called. They said my daughter's glasses were ready for pickup and I should schedule an appointment with the optician so that we can have them properly fitted. I said I'd be picking up the glasses alone and we would do the fitting another day. She insisted that the fitting was crucial, to which I replied, “I don't know if you were working last Saturday, but my daughter is really not cooperating on this whole glasses thing. I'd prefer to just pick them up.” Silence. Then she said, “I was there last Saturday, I remember you. Absolutely, you can pick them up any time.”

    I drove a taxi for extra money east of Toronto thirty years ago. Each time a taxi drove up to the front of the Greenwood Racetrack, a group of local kids would run along the sidewalk angling for position by the passenger door. One lucky kid, or rather, the most aggressive one, would open the passenger door and say "Good luck, Mister!" The man getting out of the cab would vaguely say thanks and throw the kid a quarter. It was a routine everybody knew.

    Throughout the summer, one kid caught my eye. He was bigger than most of all the other kids but pushed away by even the smallest. He never made it but never gave up. One day, his chance arrived. As I was pulling up to the sidewalk, all the kids were pushing for a cab just ahead of mine. The boy saw me and walked toward my taxi. As I positioned the passenger door right beside him, he never paused and opened the passenger door, warmly saying, "Good luck, Mister!"

    But the man neither said thanks nor flipped him a quarter. He pushed him aside so hard that the boy fell on the sidewalk. I knew it hurt him badly. I got out in less than 10 seconds, but the man was gone in the crowd. So I looked for the kid. I decided to give him $20 for the effort. By the time I spotted him he was far up ahead, walking away in the opposite direction through the crowd and his head hanging down. When I got the cab turned around I lost sight of him. I never saw him again. I'd like to find him one day and tell him that if only he had stuck around a little longer I would have given him a whole $20.

    I learned from this kid that when things seem so hopeless that you are ready to give up, it's the time when things are most likely to turn around for you.

    According to a team of researchers, an animal's ability to perceive(感知)time is linked to their pace of life.

    "Our results lend support to the importance of time perception in animals where the ability to perceive time in a very short time may be the difference between life and death for fast moving creatures." commented lead author Kevin Healy from Trinity College Dublin.

    The study was done with a variety of animals using phenomenon based on the maximum speed of flashes of light an individual can see before the light source is seen as constant. Dogs, for example, have eyes with a refresh rate higher than humans.

    One example of this phenomenon at work, the authors say, is the housefly and its ability to avoid being hit. The research showed flies "observe motion in a shorter time than our own eyes can achieve, "which allows them to avoid being hit.

    Professor Graeme Ruxton of the University of St Andrews in Scotland, who worked jointly on the research project, said in a statement, "Having eyes that send updates to the brain at much higher frequencies than our eyes do is of no value if the brain cannot process that information equally quickly. Thus, this work highlights the impressive abilities of even the smallest animal brains. Flies might not be deep thinkers, but they can make good decisions very quickly."

    In comparison, the tiger beetle(虎甲虫)runs faster than its eyes can keep up, basically becoming blind, which requires it to stop periodically to re-evaluate its prey's(猎物)position.

    Our results suggest that time perception offers an as yet unstudied dimension along which animals can specialize and there is considerable range to study this system in more detail.
