Why is pink or purple a color for girls and blue or brown for boys?

    The answer depends largely on cultural values as well as personal experiences. To the Egyptians, green was a color that represented the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. In China, children are given money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect themselves against evils（灾祸）.

    People's choice of colors is also influenced by their bodies' reactions （反应）toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally and physically. People who work in green environment have been found to have fewer stomach aches.

    Red can cause a person's blood pressure to rise and increase people's appetites（食欲）. Many decorators will include different shades of red in the restaurant. Similarly, many commercial websites will have a red “Buy Now” button because red is a color that easily catches a person's eye.

    Blue is another calming color. Unlike red, blue can cause people to lose appetite. So if you want to eat less, some suggest that eating from blue plates can help.

    The next time you are deciding on what to wear or what color to decorate your room, think about the color carefully.

    The Loss of Innocence

    Innocence is such a precious gift. It's explained as freedom from guilt or wrong doing. Just imagine never having to worry about anything and having a guilt free mind. Some people wish to save this kind of innocence from being lost from childhood to adulthood.

    What would the world be like if innocence were never lost? One way it would benefit humanity is the lack of hatred （仇恨）among the world. During youth, there may be an occasional argument, even a little physical fight, but nothing like firing a handgun at a fellow human being. And children are blind towards the racial differences of others. A kid will hang out with any other kid. It is the lack of innocence and the ignorance we learn from adults that influence children otherwise. Another benefit is the constant desire for fun and adventure. With very little if any time at all for fun，the adventurous mind is lost in time with the responsibilities placed upon adults. If innocence were kept alive, these ambitions would never depart from our lives.

    However, other people actually hate the idea of innocence lasting forever. They feel that the lack of organization and mental power of those with innocence would cause extremely destructive consequences to society in general. A large number of individuals would never have the urge to learn, work, and act upon the necessary needs for humanity to survive. Without a proper education which is usually provided by those who no longer live in a world of innocence, people would not have the desire to succeed, get a good job in life, or provide income for their families, which would hurt the lives of children.

    The lack of a good education and career would also harm the economy. As long as innocence is kept alive, no one would be terribly angered at the lack of effort people put out in the workplace, resulting in a strong decline in production and quality of needed goods.

    Maybe it is wrong in wanting to save innocence. It sure is a nice thought, though. Perhaps innocence was meant to be lost. It was God's will to make things the way they are, and there is a good purpose for everything. All that remains to be said about innocence is to enjoy it while it lasts.

    I came to study in the United States a year ago .Yet I did not know the real American society until I was injured in a car accident because after the accident I had to see a doctor and go to court.

    After the accident, my roommate called a doctor for me. I was very grateful and determined to repay him one day. But the next day, he asked me to pay him $200 for what he had done. I was astonished. He had good reason to charge me, he said. And if I wanted to collect money from the person who was responsible for my injury, I'd have to have a good lawyer. And only a good doctor can help me get a good lawyer .Now that he had helped me find a good doctor, it was only fair that I should pay him.

    But every day I went to see the doctor, I had to wait about 50 minutes. He would see two or three patients at the same time, and often stop treating one so as to see another. Yet he charged me $115 each time .The final examination report consisted of ten lines, and it cost me $215.

    My lawyer was all smiles the first time we met. But after that he avoided seeing me at all. He knew very well the other party was responsible for the accident, yet he hardly did anything. He simply waited to collect his money. He was so irresponsible that I decided to dismiss him. And he made me pay him $770.

    Now I had to act as my own lawyer. Due to my inexperience, I told the insurance company the date I was leaving America. Knowing that, they played for time...and I left without getting a cent.

    I was raised in a house where my sisters and I weren't trusted by our mother to manage our own appearance. As a result, there were rules, and trends were largely ignored. A few years ago, I was home for a visit when my mom, now in her early 70s, called me into her bedroom. We were about ready to leave for dinner. “I don't know what to wear” she complained “You girls always look so good. ”

    I paused in the doorway and looked at her, wondering if I'd misheard. “What do you mean?” I asked her. “You know what to wear" No. ”she answered. “I don't. Can you pick something?” I was so surprised.

    This was the same woman who, in 1989, told my younger sister she wasn't allowed to leave the house wearing a pair of ripped(有破洞的)jeans；the same woman who, in high school, called me while l was out at a party to ask if my hair was up. “You look better with it down, ”she told me, before I could answer I realized, suddenly, that my mother—always so strong—not only wanted my opinion, but needed it. I pulled a pair of blue jeans from the closet and a light blue sweater from her drawer “Wear this with your black shoes, ”I told her. She did My mother certainly doesn't need anyone to take care of her. In fact, she still cares for my grandmother who lives with her. But with that one question, my mother and I started the role reversal(转变)that happens with all parents and all children, from caregiver to receiver.

    Now, if I'm visiting or we're together, it's rare for her to wear anything without checking with me first. But every so often, it seems like she asks me just to be able to disagree with my answer and pick out something on her own. And when she does, I just tell her what I think of the way she looks. Sometimes it's “great”. And sometimes it's "awful."

    If you want to disturb the car industry, you'd better have a few billion dollars: Mom-and-pop carmakers are unlikely to beat the biggest car companies. But in agriculture, small farmers can get the best of the major players. By connecting directly with customers, and by responding quickly to changes in the markets as well as in the ecosystems(生态系统), small farmers can keep one step ahead of the big guys. As the co-founder of the National Young Farmers Coalition (NYFC, 美国青年农会) and a family farmer myself, I have a front-row seat to the innovations among small farmers that are transforming the industry.

    For example, take the Quick Cut Greens Harvester, a tool developed just a couple of years ago by a young farmer, Jonathan Dysinger, in Tennessee, with a small loan from a local Slow Money group. It enables small-scale farmers to harvest 175 pounds of green vegetables per hour—a huge improvement over harvesting just a few dozen pounds by hand—suddenly making it possible for the little guys to compete with large farms of California. Before the tool came out, small farmers couldn't touch the price per pound offered by California farms. But now, with the combination of a better price point and a generally fresher product, they can stay in business.

    The sustainable success of small farmers, though, won't happen without fundamental changes to the industry. One crucial factor is secure access to land. Competition from investors, developers, and established large farmers makes owning one's own land unattainable for many new farmers. From 2004 to 2013, agricultural land values doubled, and they continue to rise in many regions.

    Another challenge for more than a million of the most qualified farm workers and managers is a non-existent path to citizenship — the greatest barrier to building a farm of their own. With farmers over the age of 65 outnumbering(多于) farmers younger than 35 by six to one, and with two-thirds of the nation's farmland in need of a new farmer, we must clear the path for talented people willing to grow the nation's food.

    There are solutions that could light a path toward a more sustainable and fair farm economy, but farmers can't clumsily put them together before us. We at the NYFC need broad support as we urge Congress to increase farmland conservation, as we push for immigration reform, and as we seek policies that will ensure the success of a diverse and ambitious next generation of farmers from all backgrounds. With a new farm bill to be debated in Congress, consumers must take a stand with young farmers.

Are You a Morning Person?

    Mornings are not for everyone. Knowing that our own bodies may be wired to prefer a certain time of day is certainly a relief. But many of us still have to wake up and function during those first daylight hours. So what can you do?

    We tapped a variety of experts—from sleep experts to nutritionists to life organizational pros—to share their tricks on how to make morning less stressful and more pleasant (for) even the most after-hours of night owls.

    ①Night waking

    Poor sleep quality can explain why we sometimes wake up from eight hours of snoozing and feel like we only clocked in at four. "It's normal to have one or two awakenings, but more than that leaves us feeling groggy in the morning because of the fragmented sleep," [explains Shelby Harris, director of the behavioral sleep medicine program at Montefiore Medical Center.]

    ②The Science of snoozing

    The snooze button does more harm than good. Nodding off again sends you into a light and fragmented sleep! Multiple snoozes can leave you feeling groggier than just getting out of bed the first time.

    Instead, be honest about the time you intend to get up and then enjoy every last minute of shuteye, so you can wake up alert and ready to go.

    ③Don't ease into your workday

    It can be tempting to plow through the easy things early on-checking e-mail, scanning the headlines—but it's wise to tackle the bigger stuff first. "Getting to work on the most important tasks not only ups the chances that they actually get done, but it also leaves you with a burst of accomplishment to take with you the rest of the day," says Jason Selk, coauthor of Organize Tomorrow Today.

    ④Save social media for later

    Schedule a social media block later in the afternoon to check in when you're likely to need a break anyway, and save the morning for the important stuff.
