Chopsticks

    Right now, millions of people are digging into their food with two sticks that have school the test of time as a utensil(烹调用具)for humans. But what's so special about them? {#blank#}1{#/blank#} Personally, I think they teach us the importance of:

    If you're ever tried using them, you know that you can't get what you want by just randomly stabbing at the plate. To be able to get what you want, you have to aim for it. There's no way you can pick up everything in one go. Know what you want, and just do it. {#blank#}3{#/blank#} 

    Practice

    Using chopsticks doesn't come naturally. You can't learn to use them by just reading about them. {#blank#}4{#/blank#} It is the same with the real life. You can read as much as you like about all the things you want to do, but it will just amount to dreams and theory if you don't try actually doing it.

    Slowing Down

    {#blank#}5{#/blank#} Why? Because it allows your stomach to tell your brain you're full before you overeat. Eating with chopsticks is a slower process, but that is not necessarily a bad thing. Sometimes we need to slow down and take things one step at a time, so that we have time to think and realize that we don't have to keep charging full speed through life.

A. Aim

B. Motivation

C. What can we learn from them?

D. You have to practice using them

E. Those who eat too fast were less successful at losing weight

F. Sometimes, a little bit of focus makes the difference between failure and success

G. A common health tip is to try to eat with chopsticks when you can

    China is the biggest market in the world, and many countries such as Germany, the USA, the UK and Russia do a lot of business in China. Let's have a look at some important tips to help you be successful when dealing with these nationalities.

    First, you must be punctual (准时的) with Germans. Even 5 minutes late makes a bad impression. Being punctual is also very important in the USA. In the UK, it's important to be punctual for business meetings, but nobody expects you to be on time for a social event. Half past seven really means a quarter to eight, or even eight o'clock! With Russians, you should always be on time, though it is not unusual for them to be one or even two hours late!

    It is best to dress formally and wear dark colours when you meet people from all the four countries. In Russia, designer clothes are very common. Don't be surpri if you go to an office in the UK on a Friday and find everyone wearing jeans. Many companies have “dress down Friday”, when people wear casual (随便的) clothes.

    In Germany, first names are only used by family members and close friends, so be prepared to use titles and last names. In the USA you will usually be invited to use first names almost immediately. The British are quite informal and using first names in business is more and more common, especially among younger people. In Russia, however, nobody uses first names, so use titles and last names.

    In conversation, the British and the Americans value humour, and both like to talk about sport. The weather is also a good topic of conversation with the British and the Americans, but avoid talking about politics. In Russia, say positive（肯定的） things about their country, but avoid making complaints. The Germans, however, prefer to get straight down to business!

    So, use these tips, and you will be on your way to a successful international business career!

    Half a century ago, Japan built the world's first high-speed rail network—a network that remains the gold standard in train travel today. Currently the country is now helping Texas build its own bullet train, a potential game-changer for transportation in the state.

    When it launched on October 1, 1964, the world's first high-speed rail network was known as the “super-express of dreams.” The first line in Japan's now world-famous shinkansen network was built against all odds, in the face of fierce public opposition, technical difficulties and astronomical costs.

    Half a century ago, the system was far humbler. In 1964, the first track was a 320-mile-long link between Tokyo and Osaka that reduced the trip from six-and-a-half hours (on conventional trains) to three hours and 10 minutes, traveling at a maximum speed of 200 miles per hour. For the first time, workers could get to meetings in one city during the day and be back home drinking a beer in the local pub that night.

    Not only did the train expand mobility profoundly, but also businesses appeared around the major stops as a growing emphasis on productivity swept across Japan. Today, the shinkansen network has 1,487 miles of track, with more set to open in the coming years. It seems that everything the shinkansen touches turns to city, and regions that are off the beaten track, so to speak, benefit greatly from the economic jumpstart brought by the train. New shinkansen lines are often proceeded by aggressive marketing campaigns promoting tourism in those areas, a strategy that seems to work.

    Despite its astronomical costs, it actually has saved more. Today, over 350,000 annual trips transport tens of millions of passengers all over Japan with efficiency—the average delay time is less than a minute. A research report titled 30 Years of High-Speed Railways: Features and Economic and Social Effects of The Shinkansen by Hiroshi Okada, estimates that the economic impact from the shinkansen train network, based on the time saved from faster travel, is approximately ¥500 billion ($4.8 billion USD) per year. Okada stresses that the cultural impact is also significant, a shinkansen offers people living far from urban centers “easy access to concerts, exhibitions, theaters, etc., enabling them to lead fuller lives.”

    Japan has a plan, known as the One-Day Travel Initiative. Its goal: regardless of where you are in Japan, it should only take you three hours to get to the nearest major regional city (Tokyo, Osaka, Nagoya, Sapporo or Fukuoka). The planned impact of this hyper-mobility is to discourage the tide of migration toward urban centers, like Tokyo, and encourage decentralization.

    US scientists say they have poured cold water on the theory that washing hands with hot water kills more germs (细菌) than unheated water. The small study of 20 people found using water at 15C (59F) left hands as clean as water heated to 38C (100F).

    National Health Service (NHS) recommends that people wash their hands in either cold or warm water. In this study, scientists at Rutgers University-New Brunswick wanted to find out if popular assumptions about the benefits of warm or hot water and official guidance on hot water —given to the food industry in the US - held true. They asked 20 people to wash their hands 20 times each with water that was 15C (59F), 26C (79F) or 38 degrees (100F). Volunteers were also asked to experiment with varying amounts of soap. Before they started the tests, their hands were covered in harmless bugs. Researchers say there was no difference in the amount of bugs removed as the temperature of the water or the amount of soap changed.

    Prof Donald Schaffner said: “People need to feel comfortable when they are washing their hands but as far as effectiveness goes, this study shows us that the temperature of the water used did not matter.”

    However, the researchers accept their study is small and say more extensive work is needed to determine the best ways to remove harmful bacteria.

    In the UK, NHS experts say people can use cold or hot water to wash their hands. They say hands should be washed for at least 20 seconds and stress the importance of using enough soap to cover the whole surface of the hands. Their guidance focuses on rubbing hands together in various .ways to make sure each surface of each hand is clean.

    “At almost any given age, most of us are getting better at some things and worse at others, ”Joshua Hartshorne, an MIT cognitive(认知的)science researcher and the lead author of a study looking at how intelligence changes as we age, told Business Insider. His team quizzed thousands of people aged 10—90 on their ability to do things like remembering lists of words, recognizing faces, learning names, and doing math. Their results suggest that no matter your age, there's almost always a new peak on the horizon.

    The human brain has a remarkable capacity to recognize and identify faces, and scientists are just beginning to learn why. On average, we know that our ability to learn and remember new faces appears to peak shortly after our 30th birthday.

Having trouble focusing? The study suggests that our ability to maintain attention improves with age, reaching its peak around age 43.While younger adults may excel in the speed and flexibility of information processing, adults approaching their mid-years may have the greatest capacity to remain focused.

    Dating is tough. One of the reasons could be that we're generally bad at reading other people's emotions until we reach our late 40s.That's according to one component of Hartshorne's study, which involved showing thousands of people images of faces cropped tightly around the eye area. Participants were asked to describe the emotion the person in the photo was feeling. Performance peaked for people aged around 48.

    Many people believe that their math skills decline after they leave school and stop practicing arithmetic. But the next time you try to split up a check, keep this in mind: your ability to do basic subtraction and division doesn't reach its apex until your 50th birthday.

    Ever wonder why you always lose at Scrabble? Good news: Your best days may be ahead. According to people's scores on multiple—choice vocabulary tests, most of us don't reach our peak wordsmithing abilities until we're in our late 60s or early 70s.

    City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes, then, urban trees will likely absorb less CO₂ from the air thah forest trees.

    As we all know, the earth would be freezing or burning hot without CO₂. However, CO₂ is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe.

    Studies had shown forests readily absorb CO₂, but there hadn't been much data on whether city trees grow, die and absorb CO₂ at the same rate as forest trees do. So some researchers decided to find out.

    To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree's diameter increases as it grows, just as a person's waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years' tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO₂.

    City trees grew faster because they had less competition for light from their neighbors. In a forest, trees tend to grow close together, shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮)in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak.
