Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name —phubbers(低头族).

    Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

    Although the ending sounds overstated, the damage phubbing can bring is real.

    Your health is the first to bear the effect and result of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Dailyquoted doctors as saying, “the neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Beijing Evening News reported.

    It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

    People living in the country enjoy several advantages that people living in the city cannot enjoy. They are in close contact with nature. They make friends with trees and stones. They can own dogs. They breathe fresh air. They fight with strong winds. They listen to the songs of birds.

    This contact with nature is good for health. There are many diseases that are common in the city. but are not to be found in the country. For example, near-sightedness is almost unknown to country people.

    Because of the absence of cars, one can walk more freely in the country than in the city. There are no rules of the road, nor traffic signs to obey.

    People living in the country can easily get fresh vegetables, fresh fruit and fresh milk. And they get them at lower prices than in the city.

    Country life is economical in other ways, too. There are practically no temptations（诱惑）to waste money.

    Country people are mostly honest. They say what they mean, and make and keep promises with sincerity（诚意）. They do not put on air. They do not pretend to have those ridiculous（荒谬的）manners which are necessary in what we call polite society.

    If the crust (外壳) of the earth were not pretty solid (坚固的), it would be shaking about and moving up and down frequently. However, there are places in the rocks of the earth's crust where it isn't strongly held together—where faults exist. Along the faults, one rock might push against another with great force. The energy is changed to vibration in the rocks, so they begin to shake and we have an earthquake!

    The most famous one in North America was the San Francisco earthquake of 1906. Seven hundred people died and property (财产) damage amounted to about $425,000,000.The greatest destruction came from the fires that followed the quake.

    One of the most famous earthquakes in Europe took place in Lisbon, Portugal, in 1755. The city was destroyed and at least thirty thousand people were killed. In 1908, in Calabria and Sicily, a quake killed about seventy­five thousand people. In 1915, in central Italy, hundreds of towns and villages were damaged and thirty thousand people were killed.

    Two great earthquakes that caused great damage in Asia took place in Tokyo, Japan, and in Gansu Province in China. The Tokyo quake of 1923 killed more than one hundred thousand people and destroyed the city and the city of Yokohama, too. The Chinese quake in 1920 covered more than three hundred square miles and killed about two hundred thousand people.

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."

    Making employees feel happy and healthy at work is good for many businesses. But it isn't always an easy thing. A study suggests that only 33% of the U. S. employees consider themselves fully engaged （投身于）in work, while 16% are greatly disengaged, and 51% are just showing up.

    But there is an exception. When it comes to employee engagement, it seems that employees in small companies are doing better. According to the same research, the largest U. S. companies are at the lowest levels of engagement, while companies with fewer than 25 employees are at the highest. And in one recent report, 75% of small business workers surveyed said they were "very" or "extremely" satisfied with their role as a small company employee.

    Unlike big companies, small companies are often short of resources but the employees can get more surprises there. Small companies offer excellent career opportunities to their employees. The bosses often know their staff very well and understand their personal needs. Employees of small companies are more likely to receive free meals, paid leave, and they can even bring their pets to work.

    But of course, there are many other draws in small businesses. One of the top draws is flexible scheduling (弹性工时). Another is being able to really see the fruits of one's labor. Besides, non-cash award is also a big draw. This could be something small that reflects employees' interests and lifestyles.

    While a parental leave might lead to some financial problems, small companies may do something to improve it. "It may be impossible for a five-person team to be reduced to four for six months," writes Camillia Velasquez, head of HR management platform, Justworks. "But it could be possible to allow new parents to take on reduced hours in a work-from-home environment." This kind of method has been realized in some small companies.
