1 . I was with my mom one day as we took a walk while window shopping. We both knew we wouldn't be buying much. I remember I was looking up at the people we passed as we walked. Ladies wore 5-inch heels and bright clothes. Men wore expensive perfumes and creams that wiped away the wrinkles on their faces. An uneasy feeling started to settle in my chest. I could deny it no longer and I was ashamed of my mom.
We were in a high-class neighborhood. We lived in a small, expensive apartment building at the edge of our county. Mom chose to move there because she knew the schools were good. I realized for the first time that we didn't belong there.
I could see the heavy lines around my mom's eyes and mouth. She wore cheap clothes and worm-out shoes. Her eyes were tired from working long hours to make ends meet, and her hair was too gray for her age. She was nothing extraordinary, yet at that moment, she stood out because she was just so plain. I didn't want to be seen with her although there was no one important around to see me anyway. I felt embarrassed about being at her side. We were standing in the middle of a high-end store, and she was holding a sweater.
Mom said, “Anna, this will look good on you. Do you want it?” It Was much too expensive, but I almost thoughtlessly answered “Yes”. Then I took a closer look at the small, tired woman with a big smile and a sweater in her hands, happy to be giving me something so nice. My words died in my throat. Her clothes were worn and old because she spent her money buying me new ones. She looked so tired because she was busy working to provide for me. She didn't wear jewelry or perfumes because she was content with spending what little money she had on me. Suddenly, my mom was beautiful and extraordinarily wonderful in my eyes. I was no longer ashamed of her, but of myself.
“Do you want it?” Mom repeated.
“No, thanks,” I replied.

2 . It’s time for bed, the lights are out, and yet you’re wide awake. You do eventually manage to fall asleep, but even then, it’s a very shallow, restless sort of sleep.
Now more research suggests you needn’t look further than outside your window and at the moon for the cause of this sleeplessness. However, in a surprising twist, the findings weren’t entirely what the researchers expected. While we know that humans are a species ruled by light, the “lunar phase effect” (月相效应) affects sleep even when artificial sources of light are accounted for.
Rather than people staying up later and sleeping less during the full moon, it was just before the full moon that sleep was shorter and lighter. “It turns out that the nights before the full moon are the ones that have most of the moonlight during the first half of the night,” said Horacio Iglesia, a professor of biology at the University of Washington in The Guardian. The opposite was true just before the new moon — people tended to sleep more and go to bed earlier.
Ninety-eight participants across three Indigenous communities in Argentina wore wrist monitors tracking sleep patterns over the course of one to two months. While one community had no access to electricity, the second community had limited access, and the third community was located in an urban setting with full access to electricity.
The study also found that this lunar phase effect on sleep also appeared to have greater impact on people who had more limited access to electricity. In every community, participants’ peak (高峰) sleepless period occurred in the three to five days leading up to the full moon night, while the opposite was true for the new moon, the study authors found.
Wanting further insight, the researchers compared their data to the results of a similar study of 464 Seattle-based students at the University of Washington. The findings proved consistent.
This research supports the view that try as we may, we can’t ever fully get away from some forces of nature.

3 . Happiness is not a warm phone, according to a new study exploring the link between young life satisfaction and screen time. The study was led by professor of psychology Jean M. Twenge at San Diego State University (SDSU).
To research this link, Twenge, along with colleagues Gabrielle Martin at SDSU and W. Keith Campbell at the University of Georgia, dealt with data from the Monitoring the Future (MtF) study, a nationally representative survey of more than a million U. S. 8th-, 10th-, and 12th-graders. The survey asked students questions about how often they spent time on their Phones, tablets and computers, as well as questions about their face-to-face social interactions and their overall happiness.
On average found that teens who spent more time in front of screen devices — playing computer games, using social media, texting and video chatting — were less happy than those who invested more time in non-screen activities like sports, reading newspapers and magazines, and face-to-face social interactions.
"The key to digital media use and happiness is limited use," Twenge said. "Aim to spend no more than two hours a day on digital media, and try to increase the amount of time you spend seeing friends face-to-face and exercising — two activities reliably linked to greater happiness."
Looking at historical trends from the same age groups since the 1990s, it's easy to find that the increase of screen devices over time happened at the same time as a general drop-off in reported happiness in U. S. teens. Specifically, young peopled life satisfaction and happiness declined sharply after 2012. That's the year when the percentage of Americans who owned a smartphone rose above 50 percent. By far the largest change in teens' lives between 2012 and 2016 was the increase in the amount of time they spent on digital media, and the following decline in in-person social activities and sleep.

4 . I'm always surprised when I hear the stats (统计数据) about how little time kids spend outside. One study found children are spending less than half the amount of time outdoors than they did just 20 years ago. Meanwhile, the Kaiser Family Foundation found that kids spend an average of seven hours a day using electronic media.
My own childhood was filled with outdoor time. I built forts in the woods, rode my bike with friends, went ice skating in the winter, climbed trees and rocks, and read books on a platform in a tree on hot days.
But my nature time wasn't limited to after-school and weekend activities. I attended a public school in New York's Hudson Valley, and we spent almost all our gym outside. We spent science classes on the acres that surrounded our school, collecting samples from trees and learning about everything from chemistry to physics.
All that outside time isn't just about health and getting kids to exercise more. Several studies also have linked outside time to higher test scores, lower anxiety and aggression, more creativity and improved attention spans.
A public school in Vermont, is taking these results seriously. Eliza Minnucci’s kindergarten class there engages in Forest Mondays, during which the students spend the whole day in the woods, rain or shine.
Minnucci said that playing outdoors involves plenty of learning. It’s fairly easy to weave lessons into nature play. Kids wanted to know the names of birds, plants, rocks and clouds. We followed streams into larger streams into larger streams into a pond and created bridges with logs and stones. We even made up stories about ants and butterfly. For the older kids, we had more defined lesson plans, but we were still outside the whole time, and we would often go off on a tangent(转向)if something interesting was happening, so the learning experience was always fresh and engaging. Besides learning and moving around freely instead of sitting at desks, the kids were having fun while they learned, which made them excited for the next lesson.

5 . If you're British or live in a Commonwealth nation, Christmas doesn't end on December 25.The day after Christmas is known as Boxing Day, and the relaxing holiday is a chance to allow the celebration for one more restful day.
But its name has nothing to do with the sport of boxing, and unlike the popular idea, did not appear from a need to return unwanted gifts or clean up trash produced by Christmas gifting.
There are several theories as to how that charitable tradition became known as "boxing".Some historians link the use of the term to boxes of donations that were laid in churches during the pre-Christmas season of Advent in the early days of Christianity during the second and third centuries A.D.The day after Christmas, the boxes were opened and the money was given away to the poor.
Another possible story for Boxing Day has to do with a tradition that formed in 19th century Victorian England, where servants sacrificed（牺牲）time with their own families to cater to their employers on Christmas.On the day after Christmas, employers would give the servants a rare day off and send them home with leftovers from the family's Christmas feast for their service.
Though the reasons are lost to history, Boxing Day charity eventually fell out of tradition---and was replaced with physical and material pleasures.Today, the holiday is linked with sports, with major football rugby, and cricket matches and horse races taking place on December 26.
December 26 is also a big shopping day throughout the UK and the Commonwealth.The holiday kicks off what is known as " Boxing Week" , during which retailers（零售商）try to move old stock and shoppers compete for one last bargain of the year.In recent years, though, the American tradition of Black Friday---massive sales that take place the day after Thanksgiving each November---has become popular in the United Kingdom and has largely overshadowed Boxing Week.

6 . Have you wondered how dogs became man's best friends? On October 30, a study published in the online journal Science revealed more information about the history between dogs and humans, dating back thousands of years.
From previous studies, it was known that sometime between 15,000 to 40,000 years ago, humans first encountered a friendly gray wolf, and that forever changed the relationship. The dogs of today are descendants of and were domesticated from gray wolves.
Greger Larson from the University of Oxford, along with an international team, examined the genomes (genetic makeup) of 27 ancient dog species from remains dating back 800 to11,000 years ago. The team discovered that 11,000 years ago, there were five distinct species of dogs from Northern Europe, the Near East, Siberia, New Guinea, and the Americas. It turned out that today's dog species can trace their ancestry to one of these five ancient species. For example, the chihuahuas are descendants of ancient dogs from the Americas, while the huskies are descendants of the Siberian breed. The team also found that most of the modern European dog breeds come from two breeds - Northern Europe and the Near East. And finally, the five species trace their origin to one ancient species of wolf.
The scientists found remains of dog species in Europe are originally from the Near East. This led them to conclude that humans traveled with their dogs as they migrated from one area to another. These dogs were brought as companions or to act as guard dogs or hunting dogs.
Finally, with dogs and humans living together, the two also developed similar characteristics such as the ability to digest high-starch diets. When two species adapt to an environment in similar ways, it is known as “convergent evolution”.
As you can see, this study is already changing what we know about our favorite companion. We cannot wait to hear what else scientists unearth!

7 . While flatmates can bring about stress and difficulty, they can also be great company and develop into wonderful, lifelong friends. Before making the decision to live with a flatmate or to live alone, consider carefully all the accompanying advantages and disadvantages.
Most people join forces with a flatmate primarily due to financial problem. A shared living space also means you're responsible for only half of the rent or shared bills. Additionally, when you're splitting costs, you can afford a better apartment than you could alone. However, money can become a point of argument for flatmates as well. If your flatmate gets laid off or quits his job, you may have to pick up his bill until he's back on his feet. Your flatmate may also insist he owe less because he doesn't use the shower too often.
In addition to bills and the rent, flatmates also typically share responsibility for unpleasant tasks, such as cleaning or doing the dishes. Without a flatmate, cleaning and tidying responsibilities are yours alone. However, flatmates also frequently end up sharing plenty of other things many people would rather not: use of the TV, the bathroom, food and even clothing, for example. You may have to wake up earlier than you'd like to get a hot shower before work or give up watching your favorite show because your flatmate beat you to it.
When you live alone, you get to determine the terms of your social life, and you go home to an empty house or apartment at the end of the day. That can be preferable if you're a serious student or professional, someone who needs to work and rest in the quiet of an apartment. With a flatmate, there are unexpected guests and your social options can expand sharply. Keep in mind, however, that having a flatmate means that he may feel social when you do not, and you may have to deal with wanted house guests.

8 . A new study on the link between chili and dementia(老年痴呆) may bring bad news for spicy food addicts. Researchers have found that eating lots of chili may cause an increased risk of dementia.
The study, led by Zumin Shi, analyzed 4,582 Chinese adults aged 55 and above between 1991 and 2006 and found evidence of faster cognitive decline in those who consistently ate more than 50 grams of chili a day. “Chili consumption was found to be beneficial to body weight and blood pressure in our previous studies. However, in this study, we found negative effects on cognition among older adults,” Shi said in a press release published Tuesday.
“Chili is one of the most commonly used spices in the world and particularly popular in Asia compared to European countries,” Ming Li from the University of Southern Australia said in the press release. “In certain regions of China, such as Sichuan and Hunan, almost one in three adults consumes spicy food every day.”
The researchers said people of normal body weight may be more sensitive to chili intake and hence their memory and weight suffer a bigger impact. Worldwide, around 50 million people have dementia, and Alzheimer’s disease is the most common form that may contribute to 60 percent to 70 percent of the cases, according to the World Health Organization. At present, no treatment can cure dementia or change its progressive course.
1. According to the text, what aspect is chili consumption harmful to?| A．Body shape. | B．Body weight | C．Blood pressure. | D．Cognitive abilities. |

9 . Facebook's recent acknowledgment that social media may be making its users feel bad in some cases is a significant milestone. So far, the technology industry hardly has talked about the downsides of their products.
Academic research in a Facebook blog post in December documented that when people spend a lot of time passively consuming information, they feel worse. For example, clicking or liking too many links and posts can have a negative effect on mental health. Some researchers also believe that reading rosy stones about others leads to negative comparisons about one's life and that being online too much reduces in-person socializing. Social media may well be making many of us unhappy, jealous and anti-social. Although Facebook said that, as a result of the assessments, it would make some changes to its platform. It also highlighted some of the benefits of using the social network. It explained that “sharing messages, posts and comments with close friends and recalling about past interactions” can make people feel better. “The research and other academic literature suggest that it’s how you use social media that matters when it comes to your well-being,” Facebook said.
But that approach doesn’t seem to be an effective solution for those who can’t pull themselves away from such platforms. The Pew Research Center estimates that 24 percent of teens go online “almost constantly”. It is becoming a matter of addiction.
We need to be aware of what we are up against. Remember when we would just pick up the phone and call someone rather than email them and create greater misunderstandings. This may be an old-fashioned choice, but the right one. And maybe we should just turn away from our screens sometimes and meet our friends and family in person.
