Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

    Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.

    Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.

    The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.

    Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and he does not.

    As the G20 Leaders Summit(峰会)kicked off on Sept 4, Hangzhou, the host city, took measures to promote its reputation for entrepreneurship(企业), as well as its many beauty sports, to those overseas people.

    Although many may have been surprised when Hangzhou was chosen to host the summit over bigger cities such as Beijing or Shanghai, economic statistics suggest that it's well deserving of the honor.

    When the national economy grew at 6.7 percent in the first half of this year, the lowest in more than two decades, Hangzhou steamed ahead with a huge 10.8 percent growth, becoming one of the only two cities in China, alongside Chongqing, with a double-digit growth rate.

Walking along the streets of Hangzhou, through centuries-old paths and along the Broadway—like Yan'an Avenue, a tourist can pick up whatever he or she wants with just a smartphone, via Alipay or WeChat Pay—no cash or credit cards needed.

    And starting this month, one can also rent public bikes simply by scanning the QR code(二维码)with a smartphone.

Meanwhile, a short video showing the beauty of Zhejiang Province and its capital, Hangzhou, was being aired on CNBC channels during prime time until Sept 12.

    The promotional video, created by CNBC's Catalyst Content Studio, highlighted some of Hangzhou's most charming attractions.

From eye-pleasing beauty spots like the Qiantang River and West Lake to the towering headquarters of leading Internet corporations, the promo(宣传片)showed how the city built its culture on a long history of commerce and developed into a vast modern center of technology, imports and exports.

    Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperatures（核心体温）in cold winters and warm summers. In addition, people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity（湿度）.

In very cold climates, there is a constant danger of developing hypothermia（低体温）, which is a life threatening drop in core body temperature to below normal levels. The normal temperature for humans is about 37.0℃. However, differences in persons and even the time of day can cause it to be as much as 6℃ higher or lower in healthy individuals. It is also normal for core body temperature to be lower in elderly people. Hypothermia begins to occur when the core body temperature drops to 34.4℃. Below 29.4℃, the body cools more rapidly because its natural temperature regulating system usually fails. The rapid decline in core body temperature is likely to result in death. However, there have been rare cases in which people have been saved after their temperatures had dropped to 13.9-15.6℃. This happened in 1999 to a Swedish woman who was trapped under an ice sheet in freezing water for 80 minutes. She was found unconscious, not breathing, and her heart had stopped beating, yet she was eventually saved despite the fact that her temperature had dropped to 13.7℃.

In extremely hot climates or as a result of uncontrollable infections, core body temperatures can rise to equally dangerous levels. This is hyperthermia. Life threatening hyperthermia typically starts in humans when their temperatures rise to 40.6-41.7℃. Only a few days at this extraordinarily high temperature level is likely to result in the worsening of internal organs and death.

    Why do people lie? Many psychologists agree that lying can start from childhood. There are various reasons why children make false statements. They usually tell untruthful stories to cover up the mistakes that they have done in the past. Lying is also a way to avoid receiving punishments from parents. If parents fail to reprimand their children for making up false stories, then there is a possibility that they will continue to lie during their teenage years.

    Teenagers lie because they want to be accepted by their friends. This is the main reason why they create stories that are not true just to become presentable and acceptable to other people. In some instances, teenagers tell untruthful statements to avoid criticisms from their families and friends.

    As teenagers grow, lying becomes one of their habits. Their knowledge on making up untruthful stories becomes more developed. People lie in workplaces if they fail to meet the deadlines and if they fail to accomplish and do their tasks efficiently. Some of the common lies made in workplaces are getting sick and having emergencies at home. The danger involved in frequent lying is when it becomes a character. Frequent lying causes the development of the condition known to doctors as pathological(病态的) lying.

    Pathological lying is a mental health condition, which is associated with individuals who have the urge to tell untruthful statements. Patients suffering from it make up stories about everything and anything. These individuals pretend to meet the standards of other people who they want to please. These patients cheat other people because it gives them an unexplained pleasure. One of the best ways of treating pathological liars is to help them tell true statements and stories at all times. This may be hard for them, but as they are accustomed to it, they will start to realize that they will be more accepted by their families and other people if they stop themselves from making up false stories.

    It is obvious that all of our childhood memories are not accidental. When you are a child, every scent, every sound, every move, every toy, the first day of school, the first kiss, the first step… Everything together makes what is the personality of a man. All these are pieces of one whole entity.

    I was about 6 years old. My mom's best friend left to another town and asked my mom to stay at her place with me for two days in order to look after her two sons. One was a little older than I was, and the second boy appeared to be super grown-up, for he was already fourteen. I always enjoyed staying at their place.

    I remember the second day we were supposed to have the come-back party for my mom's friend at her place. I woke up. Mom went to work and reminded me to be nice and clean by the time she came back. I stayed with Tony, the older of the boys and suddenly somebody called him and though he was not permitted to leave me alone-he left. He said it would not be long. But it took him forever. I realized that I was alone. I could not come out of the house, so I opened the window. I was so desperate. So lonely. So betrayed. At that moment I pulled the curtain so strongly that I fell on the floor. And there I was standing-one little criminal-desperate to escape and knowing that I would be punished for destroying the curtain that was not even ours.

But then something changed. I stopped weeping. I looked around and realized that I was in a safe place, and that mom would come back and kiss me no matter what I had done.

    This was a moment of pure happiness, not the happiness of getting a new toy or a dog, or going to the party of your best friend. It was the moment of clarity for me-the first time in my life when I realized that I was happy to have my mom and that I was safe. My eyes saw the world in different shades that moment. And by the way-I was not punished for the curtain. I fell asleep on my mom's knees.
