Our spiritual intelligence quotient(精神智商), or SQ, helps us understand ourselves, and live fuller, happier lives.

    Though we're all born with SQ, most of us don't even realize that we have it. Fortunately, you don't have to sign up for classes to learn how to improve your SQ. Here are some simple steps that can lead you to this new level of understanding.

    Sit Quietly. The process of developing spiritual intelligence begins with solitude(独处) and silence. To tune in to your spirit, you have to turn down the volume(强度) in your busy, noisy, complicated life and force yourself to do nothing at all. Start small by creating islands for silence in your day. In the car, instead of listening to the music, use the time to think. At work, shut the door to your office between meetings, take a few breaths and let them out very, very slowly. Enjoy the stillness in your home after the kids are finally in bed.

    Step Outside. For many people, nature sets their spirit free. Go outside to watch a beautiful sunset. If you are walking with the dog, take the time to admire flowers in bloom; follow the flight of a bird and watch clouds float overhead.

    Ask Questions of Yourself. Ask open-ended questions, such as ‘What am I Feeling? What are my choices? Where am I heading?'

    But don't expect an answer to arrive through some supernatural forms of e-mail. ‘Rarely do I get an immediate answer to my question,' says Reverend Joan Carter, a Presbyterian minister in Sausalito, California. ‘But later that day I suddenly find myself thinking about a problem in a perspective(角度) I never considered before.'

    Trust Your Spirit. While most of us rely on gut(本能的) feeling to realize danger, spiritual intelligence pushes us, not away from, but towards some action that will lead to a greater good.

    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 stomachaches.

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 (商业的)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.

    Amazon is breaking into physical retail(零售) in a new way. The online retail giant revealed a new kind of physical store concept in a video published on Monday.

    The store, called Amazon Go, doesn't work like a typical Walmart or supermarket. Instead, it's designed so that shoppers will use an app, also called Amazon Go, to automatically add the products that they plan to buy to a digital shopping cart by scanning a QR code. They can then walk out of the building without waiting in a checkout line because Amazon will charge their Amazon account and send them a receipt(收据).

    The first Amazon Go store is located in Seattle, where Amazon is headquartered. For years, there have been rumors the e­commerce company would expand its dominance(主导地位) from digital to physical shopping. Amazon began experimenting with physical bookstores a year ago, but Amazon Go may mark its boldest(大胆的) bet on physical ones yet. By removing much of the staff needed to operate a store, Amazon keeps costs lower than traditional competitors. It's also in a strong position to bring together data on its customers' shopping habits online and offline to make better suggestions in all situations.

    However, the company could be thought of as being a threat to some of the 3.4 million Americans who work as cashiers, according to the Bureau of Labor Statistics. And Donald Trump repeatedly criticized Amazon and its founder Jeff Bezos, “He's using the Washington Post for power so that the politicians in Washington don't tax Amazon like they should be taxed.”

    “Four years ago we asked ourselves: what if we could create a shopping experience with no lines and no checkout? Could we push the boundaries of computer vision and machine learning to create a store where customers could simply take what they want and go?” The company says on an informational page about Amazon Go. For now, Amazon is starting slow. The Amazon Go is only open to Amazon employees in our Beta program, and is scheduled to open to the public in 2017.

    A new app aims to help parents interpret what their baby wants based on the sound of their cry. The free app Chatter Baby, which was released last month, analyzes the acoustic (声学的) features of a baby's cry, to help parents understand whether their child might be hungry, fussy or in pain. While critics say caregivers should not rely too much on their smartphone, others say it's a helpful tool for new or tired parents.

    Ariana Anderson, a mother of four, developed the app. She originally designed the technology to help deaf parents better understand why their baby was upset, but soon realized it could be a helpful tool for all new parents.

    To build a database, Anderson and her team uploaded 2,000 audio samples of infant(婴儿) cries. She used cries recorded during ear piercings and vaccinations to distinguish pain cries. And to create a baseline for the other two categories, a group of moms had to agree on whether the cry was either hungry or fussy.

    Anderson's team continues to collect data and hopes to make the app more accurate by asking parents to get specific about what certain sounds mean.

    Pediatrician Eric Ball pointed out that evaluating cries can never be an exact science. “I think that all of the apps and technology that new parents are using now can be helpful but need to be taken seriously,” Ball said ,“ I do worry that some parents will get stuck in big data and turn their parenting into basically a spreadsheet(电子表格) which I think will take away the love and caring that parents are supposed to be providing for the children. ”

    But Anderson said the aim of the app is to have parents interpret the results, not to provide a yes or no answer. The Bells, a couple using this app, say it's a win-win. They believe they are not only helping their baby now but potentially others in the future.

    When her five daughters were young, Helene An always told them that there was strength in unity (团结). To show this, she held up one chopstick, representing one person. Then she easily broke it into two pieces. Next, she tied several chopsticks together, representing a family. She showed the girls it was hard to break the tied chopsticks. This lesson about family unity stayed with the daughters as they grew up.

    Helene An and her family own a large restaurant business in California. However, when Helene and her husband Danny left their home in Vietnam in 1975, they didn't have much money. They moved their family to San Francisco. There they joined Danny's mother, Diana, who owned a small Italian sandwich shop. Soon afterwards, Helene and Diana changed the sandwich shop into a small Vietnamese restaurant. The five daughters helped in the restaurant when they were young. However, Helene did not want her daughters to always work in the family business because she thought it was too hard.

    Eventually the girls all graduated from college and went away to work for themselves, but one by one, the daughters returned to work in the family business. They opened new restaurants in San Francisco and Los Angeles. Even though family members sometimes disagreed with each other, they worked together to make the business successful. Daughter Elisabeth explains, "Our mother taught us that to succeed we must have unity, and to have unity we must have peace. Without the strength of the family, there is no business."

    Their expanding business became a large corporation in 1996, with three generations of Ans working together. Now the Ans' corporation makes more than $20 million each year. Although they began with a small restaurant, they had big dreams, and they worked together. Now they are a big success.

    In the early hours of the morning, Gary Miller was in his truck, traveling down the road alone to deliver. Everything seemed calm. But with the sound of a fire siren (警笛) cutting through the wind, he became alarmed. Miller, a trucker by trade, has been a volunteer firefighter for 40 years. That loud, sharp siren assured him that help was on the way.

    Most people never realize that this help is often a crew of volunteer firefighters. They make up 70 percent of the country's nearly 1.2 million firefighters. "When I was a teenager there would be many who responded. About 20 people were coming into the voluntary fire station at one siren." Miller laughed. But now, at his 54, that memory is almost ironic (讽刺的)to him. When a call comes in, his station might get only three or four people responding. He said: "People don't want to, or rather, they don't have time to volunteer." Adults' burdens have become greater. There isn't as much time left for volunteering when most people rely on a two-income household now more than ever.

    Firefighters face far more than what we imagine. The emotional stress on a firefighter stands out. "We're asked to help someone at their most vulnerable (易受伤的) time. But we can't always save the day like we hope to." Miller reflected on the case years ago. "A mother's car was hit hard, and she had two children in the backseat." By the time he arrived on the scene, there wasn't much to be done. "One child died in my arms and I felt so defeated."

    Along with the emotional stress, the physical danger is just as great. Even with the progress of equipment and new training, that's still not always enough to save a firefighter's life. In 2016, 60 firefighters died in the line of the duty. "When you respond, you never know if it is to be your last," Miller said. "And that's just a risk we take." Miller continued. "It's dangerous. But it's also the most rewarding thing I've ever done."
