Here is some must-know information from a handbook on how people behave in doing business in some countries.

In Brazil

    Brazilians are warm and friendly. They often stand close when talking and it is common for them to touch the person on the shoulder. People often greet each other (particularly women) with light cheek kisses. Schedules tend to be flexible, with business meetings sometimes starting later than planned. But to be safe, be on time. Meals can stretch for hours—there's no such thing as rushing a meal in Brazil. Lunches also can start in the mid to late afternoon. Brazilians are social, preferring face-to-face communication over mails or phone calls.

    In Singapore

    Singaporeans shake hands when they meet and often also greet each other with a small, polite bow. Business cards should be offered and received with two hands. Arriving late is considered disrespectful. So be on time. Efficiency(效率) is the goal, so meetings and dealings often are fast-paced. Singaporeans are direct in their discussions, even when the subject is about money. Rank is important and authority is respected. This determines both people interact in meetings. For example, people avoid disagreeing outright with someone with a higher rank.

    In the United Arab Emirates

    In the UAE, status is important, so the most senior or oldest should be greeted first with their titles. The handshake seems to be longer than elsewhere. So, do not pull away the handshake. Women should cover themselves when it comes to dress. Men also tend to be covered from neck to elbows(肘部) and down to the knees. People do not avoid entertaining in their homes, but they also hold business meals at restaurants. Touching or passing food or eating with your left hand is to be avoided. When meetings are one-to-one, if your host offers you coffee, you should refuse. It might seem odd, but it is a cultural tradition. Coffee should only be accepted if it is always set out or presented.

    In Switzerland

    The Swiss tend to be formal and address each other by last name. They also are respectful of private lives. You should be careful not to ask about personal topics. Punctuality (守时) is vital, something that comes from a deep respect for others' time. Arrive at any meeting or event a few minutes early to be safe. They also have clear structure in their companies. Higher-ups make the final decisions, even if others might disagree. Neat, clean dress is expected. The Swiss follow formal table manners. They also keep their hands visible at the table and their elbows off the table. It is polite to finish the food on your plate.

    Most people, when they travel to space, would like to stay in orbit (轨道) for a few days or more. And this stands to reason, if you're paying $ 20,000 for your trip to orbit! So in order for tourism to reach its full potential there's going to be a need for space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel—private rooms, meals, bars. But they'll also offer two unique experiences: impressive views—of Earth and space—and the endless entertainment of living in zero gravity—including sports and other activities that make use of this.

    The hotels themselves will vary greatly—from being quite simple in the early days to huge luxury (奢侈的) structures at a later date. It's actually surprising that as later as 1997, very few designs for space hotels were published. This is mainly because those who might be expected to design them haven't expected the costs to come down far enough to make them possible.

    Lots of people who've been to space have described vividly what it's like to live in zero gravity. There are obviously all sorts of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don't need to sleep much living in zero gravity, so you'll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below.

    Of course all good things have come to an end, unfortunately. And so after a few days you'll find yourself heading back to the earth. You'll be thinking how soon you can save up enough to get back up again-or maybe you should change jobs to get to work in an orbiting hotel!

    With her pretty face and soulful voice, Zhang Bichen was thought a possible champion when she first set foot on the stage of the TV show The Voice of China.

    On Oct 7, 2014, the 25-year-old girl won the fierce competition and received the title of the “Voice of the Year”. Zhang's dream of being a singer star came true as last. What impressed people was not only Zhang's singing skills, but her willingness to make an effort. “I gained the opportunity to sing on The Voice of China,” she said.

    In fact, being a singer has always been her dream. She wanted to apply to a college for singing, but her parents insisted that she should have an easy job after graduation because she did very well at school. So Zhang gave in to her parents and learned French at university. However, in the first year of her college, she was discovered by a South Korean company when she entered a singing competition. To realize her dream, Zhang signed a contract（合同）with the company, started her career in South Korea, and became a member of a band.

    “My company had rules that did not allow us to use cell phones. During the first few months after I arrived in South Korea, a totally unfamiliar country, I felt terribly homesick. But I could only phone my parents in the restroom when nobody noticed.” Zhang said. “When I did not have much income, I had to eat noodles every day for months.”

    It was her positive attitude and outgoing character that helped her through. “When I feel down, I tell myself it is not winning or losing that matters. The most important things are standing on the stage and singing for people.” she said.

    Internet slang refers to a variety of slang languages used by different people on the Internet. It is difficult to provide a standardized definition of Internet slang due to the constant changes made to its nature. However, it can be understood to be a type of slang that Internet users have popularized, and in many cases, have coined. Such terms often begin with the purpose of saving keystrokes or to compensate(补偿)for small character limits. Internet slang consists of a number of different ways of speaking, sub-languages, expressions, spelling techniques and idioms that have obtained most of their meaning on the Internet.

    Love it or hate it, there is no escape from Internet slang. It has become popular among the teenagers. Just like US teenagers use “LOL”(laugh out loud) when commenting on a funny video, China's post-00s generation, a group born between 2000 and 2009, like to use “XSWL” (laughing my head off). Acronyms(首字母缩略词) and shortened expressions may be popular as they offer shorter ways of communicating. For teenagers, they could also allow them to communicate in their own way.

    Understanding the most common acronyms and texting symbols can help to decode and decipher any text message, email or instant message online. Here are some of the most popular symbols, abbreviations, and acronyms you are likely to stumble upon when texting or receiving messages and chatting on line. OMG: Oh my God; BRT: Be right there; TTYL: Talk to you later; JK: Just kidding; G2G: Got to go; NMU: Not much, you? RBAY: Right back at you; IDC: I don't care.

    Some people think that Internet slang affects the language negatively. However, Melbourne University linguist Rosey Billington doesn't agree.

    “When you are able to use language in a creative way, you show you are linguistically knowledgeable because you know the language rules well enough to use words in a different way.”Billington told News.com. Au .Her view is supported by two linguists, Lauren Spradlin and Taylor Jones.

    It's undeniable that spending time outdoors and in nature lifts our spirits and makes us feel more centered and at peace. When we breathe in fresh air, and enjoy the beauty of trees, streams and oceans, we naturally tend to feel more connected to ourselves and others.

Over the past decade, scientists have been exploring why nature — and dirt specifically — is such a powerful tool in improving our mood. According to researchers, the secret may lie in the microbes (微生物)of the soil. One bacterium specifically—-Mycobacterium Vaccae (M. Vaccae) —has been identified as having the power to affect our moods and cognitive function as well.

    Experiments conducted at Sage Colleges in New York found that contact with M. Vaccae can increase serotonin levels in the brain — a chemical that is associated with higher levels of happiness, increased focus, and reduced anxiety. In order to explore how the bacteria can improve learning, researchers Dory Mathews and Susan Jenks experimented with mice in a maze. Mice that ingested the bacteria navigated the maze twice as fast as the control group and proved less anxious as well.

    Humans can absorb M. Vaccae just by playing in the dirt. We take in it when we breathe, we consume it in organic vegetables, and it can also enter our bloodstream through skin contact, especially where we have open cuts. This may explain why children in school perform better after break.

    Neuroscientist Christopher Lowry at the University of Bristol in England believes that he has identified why this incredible bacterium works. "What we think happens is that the bacteria activate immune cells, which release chemicals called cytokines that then act on receptors on the sensory nerves to increase their activity.”

    Beyond the power of M. Vaceae, scientists have been proving for decades that exposure to dirt, and the huge number of microbes found in dirt, can strengthen our immune system. When our body comes into contact with bacteria, it stores die information in a type of library and can then use that information to fight sickness and infection more effectively.

    Happiness, focus, less anxiety… I'll take a double dose of dirt; please!

    China will soon issue licenses for the commercialization(商业化) of 5G, as the country has already established(建立)a competitive advantage in the superfast wireless technology.

    The Ministry of Industry and Information Technology said 5G is entering a critical period of commercial deployment(部署)globally and China's 5G industry has established a competitive advantage through a combination of innovation(创新) and open cooperation.

    Many foreign companies, including Nokia and Intel, have participated in China's technical 5G tests. These foreign companies have already participated in three phases of tests organized by China to get their 5G products and solutions ready for commercial use in the country.

    "With joint efforts of all parties, China has built a foundation for commercialization of 5G," the ministry said, adding it will issue commercial 5G licenses in the near future, a clear sign China will soon officially enter the first year of 5G.

    China's big three telecom carriers are forecast to spend 900 billion to 1.5 trillion yuan ($134 billion to $223 billion) in total on 5G network construction from 2020 to 2025, according to a report from the China Academy of Information and Communications Technology. In comparison, Chinese telecom operators spent 720 billion yuan on 4G network construction from 2014 to 2018.

    In 2019, China Mobile plans to build 30,000 to 50,000 5G base stations this year, while China Telecom is looking to have 20,000.
