    How do I book a place on Airbnb?

    When you book a place on Airbnb, you are making arrangements to stay in Someone's home. Each host has their own style of hospitality, starting with how. They like to get to know their guests. Some hosts want to approve reservations, while others are comfortable letting you book their place instantly without waiting for approval.

    ⒈Complete Your Personal Details

    In either case, it's important to know that Airbnb is a community that relies on trust. Complete your personal details before you request a reservation with a host, so they can know a little bit about you when they confirm. Your personal details should include photos and verifications (证明）, especially because some hosts require guests to have a profile photo and verified ID in order to book.

    ⒉Find the Right Place

    With over 800,000 unique listings around the world, you'll want to make sure the place you choose has everything you need for a comfortable and memorable trip. When searching for a place, make sure to include your dates and number of guests to get the most accurate pricing. Read reviews, descriptions, house rules, and facilities for each place to see if it's the right fit for your trip. You can always contact the host if you have any questions about their home.

    ⒊Book It!

    You've found the perfect place, and now it's time to make it official. This is where the host's preferred way of booking will determine how you'll confirm your reservation.

    Instant Book

    For hosts who don't want to approve each reservation, you'll see a button on their listing that says Instant Book. Like the name suggests, you can confirm a reservation at these places right away.

    Request to Book

    Many hosts prefer to approve reservations before they're final. In this case, you'll see a button on their listing that says Request to Book. To submit a reservation request, you'll need to enter your payment details.

    Hosts have 24 hours to accept your request, and your reservation is automatically confirmed once they do.

    Pre-approvals and Special Offers

    If you decide to contact the host to ask questions before attempting to book, the host may respond to your message by inviting you to make a reservation with either a Pre-approval or a Special Offer. A Pre-approval is an invitation to finish booking for the dates and number of guests you noted in your message. A Special Offer gives the host the opportunity to provide special pricing, dates, and other reservation details before you book.

    Whether you are entering the job market for the first time or you are already at work, you have to know the various fields where you can work and the types of jobs available per field. Now it is time that you gained basic knowledge about ten common fields of work and some types of jobs in that field. Here they are:

    Technology Jobs

    The technology field is always growing very fast, so job growth in the field is also constantly booming. Here, you are always in the cutting-edge. However, you always have to update your skills when you are working in technology. Engineering and IT graduates are people who primarily do work related to technology.

    Education Jobs

    Here is a field which allows you to share your knowledge with others. You need subject-matter knowledge and teaching skills to be in this field. Most of all, you need plenty of hearts. While the everyday life of teachers may be tiring, education is one of the most fulfilling (令人满意的) fields to enter. You may need some certifications, though.

    Healthcare Jobs

    Healthcare professions enable you to use a great knowledge base of the human body and of latest health advances so you can save lives, provide comfort, cure illness, and maintain people's health. Work here is often done in hospitals and private clinics.

    Science and Mathematics

    Discovering new knowledge is the primary task of scientists and mathematicians. Training here takes a long time and goes beyond getting a bachelor's degree. However, the work will be fulfilling, especially that you may be at the edges of revolutionary discoveries. You can also use any experience and research skills acquired in either field to work in regular employment settings.

    If you like texting and are trying to lose weight, a new study found that using texting to track(追踪) diet and exercise habits may help you lose weight.

    Previous research has shown that keeping food and exercise diaries improves the likelihood of success when you are trying to lose weight. Using a computer or a pen and paper to record information, however, can be a burden and cause some people to give up.

    Duke University researchers said using text messages to track eating and exercise habits can save time, and increase the chances that people will stick with their weight-loss rules.

    The study included 26 obese women with an average age of 38. The women used daily texting as part of their weight-loss program. The text messages focused on tracking personalized goals, such as avoiding sugary drinks or walking 10,000 steps a day. Messages also provided brief feedback (回复) and tips.

    Every morning, the women received a text from an automated(自动的)system that said, "Please text yesterday's personal information of steps you walked and how many sugary drinks you had." Based on the women's responses to the text message, the system sent another text with personalized feedback and tips.

    After six months, the women who used daily texting lost an average of nearly 3 pounds, while another group of women who used traditional methods to keep food and exercise diaries gained an average of 2.5 pounds, according to the study, which was published in the Journal of Medical Internet Research.

    "Text messaging has become popular and may be an effective method to simplify tracking of diet and exercise behavior," Dori Steinberg, who was responsible for this research, said.

    Steinberg said, "Text messaging offers several advantages compared to other self-monitoring methods. Unlike web-based diet and exercise diaries, data in a text message can be entered quickly on nearly all cellphone platforms so it is very convenient to receive feedback. Besides, because of the limited number of words used in text messages, it saves time."

New archaeological discovers suggest that trade between Europe and Asia along the Silk Road probably began in some form many centuries earlier than once thought. The findings, coupled with a widening range of scientific and historical research, could add a fascinating new page to the epic of the Silk Road.

The latest and most surprising discovery is pieces of silk found in the hair of an Egyptian mummy from about 1000 BC, long before regular traffic on the Silk Road and at least one thousand years before silk was previously thought to be used in Egypt. Other research may extend human activity along this route back even further, perhaps a million years to the migration of human ancestors into eastern Asia.

The official origin of East-West commerce along the road is usually placed in the late 2^nd century BC when an agent of the Chinese Emperor Wu-di returned from a dangerous secret mission across the western desert into the remote high country of Central Asia. The agent, Zhang Qian, travelled as far as Afghanistan and brought back knowledge of even more distant lands such as Persia, Syria and a place known as Lijien, perhaps Rome. Historians have called this one of the most important journeys in ancient times. His journey opened the way for what have been thought to be the first indirect contacts between the ancient world's two superpowers, China and Rome. Chinese silk, first traded to central Asian tribes for war horses and to the Parthians of old Persia in exchange for acrobats and ostrich eggs, was soon finding its way through a network of merchants to the luxury markets of Rome.

But the new discoveries show that Chinese silk was apparently present in the West long before the Han emperor started organized trade over the Silk Road. The research could change thinking about the early history of world trade and provide insights into the mystery of just how and when Europe and the Mediterranean lands first became aware of the glorious culture at the other end of Eurasia.

    The idea that computers have some amount of "intelligence" is not new, says Ralph Haupter, the president of Microsoft Asia, pointing as far back as 1950 when computer pioneer Alan Turing asked whether machines can think. "So it has taken nearly 70 years for the right combination of factors to come together to move AI from concept to reality," says Haupter.

    It is predicted that the development of artificial intelligence will be the story of the coming generations, not just the coming year, but as 2019 gets underway, you'll find AI will begin to touch your life in many ways according to some researchers.

"Personal assistant AIs will keep getting smarter. As our personal assistants learn more about our daily routines, I can imagine the day I need not to worry about preparing dinner. My AI knows what I like to eat, which days of the week I like to cook at home, and makes sure that when I get back from work all my groceries are waiting at my doorstep, ready for me to prepare that delicious meal I had been longing for." —Alecjandro Troccoli, senior research scientist, NVIDIA.

"Thanks to AI, the face will be the new credit card, the new driver's license and the new barcode (条形码). Facial recognition is already completely transforming security with biometric capabilities being adopted, and seeing how technology and business are connected, like Amazon is with Whole Foods, I can see a near future where people will no longer need to stand in line at the store." —Georges Nahon, president, Orange Institute, a global research laboratory.

"2019 will be the year AI becomes real for medicine. By the end of the year we're seeing solutions for population health, hospital operations and a broad set of clinical specialties quickly follow behind." —Mark Michalski, executive director, Massachusetts General Hospital.
