Mark is always engaged in his work. But this time he felt that it was time for him to take part in his community, so he went to the neighborhood meeting after work. The area city council woman was leading a discussion about how the quality of life was on the decline. The neighborhood faced many problems. Mark looked at the charts taped to the walls. There were charts for parking problems, crime, and for problems in empty buildings. Mark read from the charts, “Police patrols cut back, illegal parking up 20%”. People were supposed to suggest solutions to the council woman. It was too much for Mark. “The problems are too big”, he thought. He turned to the man next to him and said, “I think this is a waste of my time. Nothing I can do would make a difference here.”

    As he neared the bus stop on his way home, Mark saw a woman carrying a grocery bag, and a baby. As Mark got closer, her other child, a little boy, suddenly ran into the street. The woman tried to reach for him, but as she moved, her bag shifted, and groceries started to fall out. Mark ran to take the boy's arm and led him back to his mother. “You gotta stay with mom,” he said. Then he picked up the stray groceries while and the woman smiled in relief. “Thanks,” she said, “You've got great timing.” “Just being neighborly,” Mark said. As he rode home, he glanced at the walls of bus. On one of them was “Small acts of kindness add up.” Mark smiled and thought, “Maybe that's a good place to start.”

    Electric devices can seem like a “third party” in some relationships because some partners spent more time on them than with each other.

    When Amanda Gao, a 26-year-old white collar worker in Beijing, went to a hotpot restaurant with her boyfriend on Friday night several weeks ago, she expected that they would have a good time together. To her disappointment, however, it did not turn out that later. As soon as they were led to their seats and she began to order dishes, he buried himself in his mobile phone.

    “It seemed that his phone was making its way between us. A date that should have belonged to us turned into one where my boyfriend dated a third party and I felt left out.” Gao said. Some people, like her, have found electronics have been sabotaging(破坏) their romantic relationships.

    A study, published in the journal Psychology of Popular Media Culture, in April, 2017, questioned nearly 200 college aged adults who were in committed(真诚的) relationships to report on their and their partner's smartphone dependency. The results showed people who were more dependent on their phones were less sure about their relationships, and people considered their partners excessively(过度地) dependent on their devices were less satisfied in their relationship.

    Lin Yuan, a relationship advisor in Beijing, noted that as more and more electronics come out and spice up people's lives, they are at the same time becoming a third party in relationships, especially for young people.

    Lin said she knew of some people who suggest that electronics should be kept out of bedrooms, which she considered challenging and hard to be put into practice for most couples. She recommended that if people are feeling neglected in their relationship, they need to respectfully let their partners know their feeling. “Communication is always the best and the most efficient way.” she said.

A Teenage Inventor

    The world could be one step closer to quick and inexpensive Ebola detection thanks to a teenager from Connecticut.

    Olivia Hallisey, a junior at Greenwich High School, was awarded $50,000 in the Google Science Fair for her new method that detects Ebola, a virus that causes bleeding from different parts of the body and usually causes death. Olivia's method is to ask patients to put their saliva (唾液) onto a testing card. The card changes color if the person is catching Ebloa. Present Ebloa tests take up to 12 hours and cost $1,000. Olivia's method, however, can be done just in 30 minutes for about $25. Besides, the sample (样本) doesn't have to be put in a refrigerator thanks to the silk material Olivia uses to produce the testing cards.

    Olivia was inspired to deal with this global problem after watching the news that more than 10,000 people died from Ebola in West Africa. She was particularly worried about the fact that, while the acts of involvement can improve survival rates, present detection methods are costly, time-consuming and require complex tools. Olivia got help from her science research teacher. She drew out directions from past research, and figured out detection systems that have proven to work with other diseases, including Lyme disease and yellow fever.

    "What affects one country affects everyone," Olivia told CNBC. "We have to work together to find answers to the huge challenges which cause harm to the global health." The Connecticut's teen, who hopes to become a doctor one day, was named the Google Science Fair winner in the competition of 20 competitors from across the globe. The fair is open to young people between the ages of 13 and 18 in most countries.

    Olivia hopes her success will inspire other girls interested in science and computers. "I would just encourage girls to try it in the beginning, and remind them that they don't have to feel naturally drawn or feel like they have a special talent for maths or science," she told CNBC, "but just really look at something they are interested in and then think how to improve something or make it more enjoyable or relate it to their interests."

    Beneath the water in the China's Qiandao Lake lies a hidden treasure. The ancient city of Shi Cheng (also known as Lion City), located in the province of Zhejiang, has been submerged underwater for 53 years. Shi Cheng was founded about 1,300 years ago in a valley surrounded by the Five Lion Mountains. When the Chinese government decided they needed a new hydroelectric power station (水力发电站)， a dam and man-made lake were constructed and the city was left at the bottom of this new body of water. Now, it sits at depths ranging from 85 feet to about 103 feet.

    Much like the Machu Picchu ruins in Peru, this underwater city remained forgotten until some renewed interests lead to its rediscovery. Qiu Feng, a local official in charge of tourism thought about utilizing Shi Cheng for entertainment on the lake and as a destination for diving clubs. On September 18, 2001, scuba divers made their first attempt underwater. "We were lucky. As soon as we dived into the lake, we found the outside wall of the town and even picked up a brick, "Qiu told Guangzhou Daily in an interview. More research was conducted, and it was discovered that the entire town was intact (1881), including wooden beams and stairs. After the initial findings, international archaeologists and a film crew then recorded the preservation of the lost ruins.

    Looking at surface of the lake, dotted with over 1,000 islands, you'd never know that an entire city was below.

    It's incredible to think that after all this time, the structure still remains intact and we could one day visit it. Until then, Shi Cheng will continue to remain inconspicuously submerged.

    Black Friday

    The day after Thanksgiving is the start of the holiday shopping season. Thanksgiving is always on a Thursday, so the day after is a Friday. This day has come to be known as Black Friday. It has been the busiest shopping day of the year since 2005.

    Most stores offer great deals on Black Friday. They open their doors in the small hours of the morning. They try to attract shoppers with big discounts. Some items like TVs are much cheaper than usual. Stores may even lose money on these items. They hope that shoppers will buy gifts for other people while they are in the store.

    Black Friday is a great time to get good deals. The problem is that there are not enough low-priced items to go around. Each store may only have a few. These items are in high demand. People stand in long lines to get such great deals. They may line up hours before a store opens. They may be hoping to get a low price on a TV or laptop, but not everyone who wants one will get one. Some people leave disappointed.

    The situation can be tense(紧张的). Some Black Friday events have been violent. Large, eager crowds have trampled(践踏) workers. Fights have broken out over toys or people cutting in line. People have shot one another over parking spots. But most Black Friday events are safe and fun. Still, if you plan on going, expect large crowds and a bit of pushing and shoving.

    So where does the name "Black Friday" come from? It was first used in Philadelphia in the 1950s. The police called this day Black Friday because of the heavy traffic it drew. In the 1960s, spread across the country. It seems that it is here to stay.

    Now people all over the country take part in the event known as Black Friday. It is even spreading to other parts of the world. Stores have held Black Friday events in the U.K., Australia, and Brazil since 2012. In Costa Rica Black Friday is known as "Viernes Negro." And in Mexico, stores offer an annual weekend of discounts. They call it "El Buen Fin," which means "the good weekend" in Spanish. I guess the language of savings is universal.

    Before uploading a photo of ourselves to social media, chances are that we'll use an app to smooth our skin, make our eyes look bigger, and lips fuller. With a couple of taps on our mobile phone, we can get a quick fix and present the "best" version of ourselves to the world. However, the problem is, when we simply edit our imperfections away, we're also changing the way we look at ourselves.

    Last month, researchers published the article Selfies – Living in the Era of Filtered(过滤的) Photographs. The article analyzed photo editing apps' bad influences on people's self-respect and their possibility to cause appearance anxieties. The researchers also warned that such apps make it difficult to tell the difference between reality and fantasy. "These apps allow one to change his or her appearance in minutes and follow an unrealistic standard of beauty," the article reads.

    In the past, people may have compared their looks to those of famous persons. But for today's young people, beauty standards are most likely set by what they see on social media. "From birth, they are born into an age of social platforms where their feelings of self-worth can be based purely on the number of likes and followers that they have, which is linked to how good they look." British cosmetic doctor Tijion Esho told The Independent. This is why many young people suffer an identity trouble when it comes to appearance.

    "Now you've got this daily comparison of your real self to this fake self that you present on social media." Renee Engeln, a professor of psychology, told the HuffPost website. Engeln further pointed out that when people spend too much time making such comparisons, they may become "beauty sick" and find it difficult to accept what they actually look like. "Because between you and the world is a mirror, it's a mirror that travels with you everywhere. You can't seem to put it down." she told The Washington Post. So when we look in a real mirror, we shouldn't think to ourselves, "Do I look as good as myself in the filtered photos?" Instead, we should think, "I feel good; I have my health."
