It's a Saturday morning, and I am eager to fly away.My husband and I will meet up with our son on the other side of the country to learn and explore together.Sitting now at the airport gate,my husband wanders away to stretch his legs.Moments later,he returns and whispers in my ear.I rise and follow him around the comer toward a large window facing the landing area.

    On the road, Marines stand straight and the plane door is open.A white hearse(灵车）is parked nearby.A man and a soldier stand on either side of a woman,supporting her and waiting for what is to come.Airport personnel stand in reverent stillness.A few people place their hands over their hearts,as I have done.We're joined in witness,sending respect to an honorable soldier whose name we'll never know.

    The woman looks heartbroken. She cries, knowing she will never hear "Mom”from her son. She'll never feel his tender embrace or enjoy his sweet peck on her cheeks.Another man's face is twisted because of the grief.His son,the tiny boy he no doubt wrestled playfully,the teen he probably taught to drive,and the son he stood so proudly by,now lives only in his memory.

    Those behind the glass stay silent, reflecting on this loss, as the family and soldiers leave.Some of us women, with sorrowful expressions, move slowly away, sharing a mother's profound grief .Soon,each of us will fly off in planes and return to an ordinary life made extraordinary by this soldier's courage，by this family's sacrifice and by this love shared by all that look out of the window.

    Rent control, like all other government-mandated（强制执行的）PRICE CONTROL,is a law placing a maximum price, or a "rent ceiling," on what landlords may charge tenants（房客）.It is a program designed to stop rents from rising rapidly and is used mainly in large urban areas where there are more people than housing. In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in the apartments. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, almost all the critics conclude that rent control is destructive. They say after a long time, rent control may have negative effects.

    In a 1990 survey of 464 people published in the May 1992 issue of the American Economic Review,93% of US respondents agreed that a ceiling on rents reduces the quantity and quality of apartments available. Landlords are too cautious (perhaps too smart) to put their faith in rental apartments because they know that the rental-controlled apartments cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent-controlled. As a result, new apartments are not built. Many people who need apartments cannot find any.

    Some theorists argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low-paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. The price, which is the wage that employers must pay, increases. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim, an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.

    Supporters of the minimum wage say that it helps people keep their dignity, Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.But the supporters make a big error. They fail to realize that it is possible for such a law to increase wages beyond the value of what the workers contributes.

    Economic theories predict the results of economic decisions such as decisions about farm production, rent control, and the minimum wage. The predictions may be correct only if "other things are equal". Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.

    The next generation of artificial intelligence (AI) may be sitting right beneath you, at least if furniture maker Ikea has any say in the matter. The Swedish furniture company's “future-living” research lab in Copenhagen is conducting a survey to understand what people want when it comes to smart furniture.

    AI is now walking into more aspects of people's daily lives. Self-driving cars are just around the corner, and AI robots can play and beat the best players of strategy games. As smart home technologies have become more ubiquitous, products ranging from smart electrical outlets（插座）to smart smoke alarms are flooding the market. Therefore, it's not surprising that Ikea would be moving in the same direction.

    Exactly why people would want their sofa or bed frame to speak to then, track their daily movements or offer help is not yet clear. Though Ikea's the new survey doesn't directly answer that question, it does provide a hint of what people would feel comfortable with. Most participants wanted a more human0like form of virtual（虚拟的）assistants, as opposed to one that is more robotic. In terms of the ideal gender（性别）of the assistants, the most popular choice was neither male nor female. Few wanted a religious form of AI.

    Just as with human friends, most wanted AI friends that were like them, affirming their own worldview. They wanted an AI assistant that was reasonably intelligent-that could collect data to predict what a person wanted before he or she asked, and that could prevent someone from making mistakes.

    This is not the first time that Ikea has set foot in the field or futuristic technologies. In addition to wireless charging tables and chainless bikes that never rust（生锈）, the furniture giant has also pictured smart kitchens that can cook the best meal. To decide on how intelligent you want your next sofa or bookshelf to be, you can take Ikea's survey online.

    I owe my father a huge thank you! Sure, I need to thank him for all those years of paying my bills, fixing my bikes, and providing a shoulder to cry on. But this year I realized that his contributions to my childhood were much more than that.

    I grew up as Daddy's Little Girl. If I had a problem that needed fixing or a question that needed answering, he was the one I ran to. He helped me get through everything from math homework as a high school student to career choices as a young adult. He always expected that I do my best in whatever I did, and he believed I could succeed in anything I put my mind to. As a result, I learned to hold myself to those same standards. He always showed me unconditional love, which helped me learn to love myself. It was something I'd taken for granted until I realized from talking with my friends that they had no similar view of their self worth. Having fathers that didn't believe in them left them to grow up not believing in themselves.

    As I was growing up, my father also modeled how a woman should be lavished. He treated my mom with love and respect. As a result, I grew to expect nothing less than that from the men I dated and from the man I would eventually marry. Dad was a living picture of godliness (虔诚), honesty and responsibility. It was only recently that I realized what a deep effect fathers have on their daughters' lives. That is why I want to thank my dad for the godly example of love that he has been to me throughout my life.

    There are always stories in the life that can hardly be forgotten and will restore our hope for holidays every time we recollect.

    Johnny and I, along with our two young sons, Barry and Doyle, lived in a village in southern Alabama in 1979. We had bought the boys a bicycle for the New Year, and had hidden it in the garage ,where Johnny would assemble (组装)it on New Year⁵ s Eve after the kids fell asleep. But that day, Johnny had to go to Brookley Air Force Base in Mobile, an hour away, to repair a jet. I had my hands busy with baking, preparing for holiday dinner and caring for two energetic boys.

    Just as I was making the chocolate cake, a neighbor knocked on the door. It was Beatrice, who was the only person on our road with a telephone. The base had called to say that a heavy tool had come apart suddenly, hitting Johnny's arm and breaking the bone. My brother Otto took me to the base hospital while my mother stayed with the children.

    We got there to find Johnny with a cast (石膏)on his arm, anxious to get home regardless of the doctor's orders. It was New Year's Eve, Johnny argued, and he had the bike to assemble for his boys. The doctor said he'd consider dismissing him the next morning if Johnny could find someone to drive him home. On New Year's morning, Johnny called the base and was told everyone was off duty; there was no one to drive him home. Johnny kept making calls. At last, a big blue car with the Air Force sign rolled up.

    I was putting dinner on the table when hearing the car. We were thrilled to see Johnny assisted by a uniformed Air Force officer. With Otto's help, Johnny assembled the boy's gift, and they all had a good time that afternoon. Our hearts were full of gratitude to the people who had gone the extra mile to bring us together.

    A study examining the children of people evacuated(撤离) during the WWII showed the daughters of female evacuees were up to four times more likely to suffer from serious mental health conditions compared to those whose parents stayed at home.

    In the largest enquiry ever of its kind, researchers examined the health records of 3000 children of Finnish people evacuated to Sweden during the 1941-1945 conflict with Soviet Russia. The evacuees, many of whom were at a pre-school age, were placed with foster families in Sweden and were forced to learn Swedish, later returning to Finland. The study found that the female children of these girls had an increased risk of being hospitalized for conditions such as depression. However, this was not the case with children of boys evacuated during the war.

    The study could not determine why. One possibility is that the stress of the evacuees' experience affected their psychological development in ways that influenced their parenting style. Another possibility is that the evacuees' experience resulted in epigenetic changes—changed in the way genes are expressed. For example, the researchers mentioned an earlier finding that Holocaust survivors have higher levels of methyl groups bound to the FKBP5 gene and have passed his change on to their children. This higher level of methyl groups appears to change the production of cortisol, a hormone(荷尔蒙) that controls the stress response.

    "The Finnish evacuation was intended to protect children from the harm associated with the country's wars with the Soviet Union", said study co-author Dr Torsten Santavirta, from Uppsala University.

    "Our observation of the long-term psychiatric(精神病的) risk that reached into the next generation is concerning and stresses the need to weigh benefits as well as potential risks when designing policies for child protection".
