Amazon is breaking into physical retail(零售) in a new way. The online retail giant revealed a new kind of physical store concept in a video published on Monday.

    The store, called Amazon Go, doesn't work like a typical Walmart or supermarket. Instead, it's designed so that shoppers will use an app, also called Amazon Go, to automatically add the products that they plan to buy to a digital shopping cart by scanning a QR code. They can then walk out of the building without waiting in a checkout line because Amazon will charge their Amazon account and send them a receipt(收据).

    The first Amazon Go store is located in Seattle, where Amazon is headquartered. For years, there have been rumors the e­commerce company would expand its dominance(主导地位) from digital to physical shopping. Amazon began experimenting with physical bookstores a year ago, but Amazon Go may mark its boldest(大胆的) bet on physical ones yet. By removing much of the staff needed to operate a store, Amazon keeps costs lower than traditional competitors. It's also in a strong position to bring together data on its customers' shopping habits online and offline to make better suggestions in all situations.

    However, the company could be thought of as being a threat to some of the 3.4 million Americans who work as cashiers, according to the Bureau of Labor Statistics. And Donald Trump repeatedly criticized Amazon and its founder Jeff Bezos, “He's using the Washington Post for power so that the politicians in Washington don't tax Amazon like they should be taxed.”

    “Four years ago we asked ourselves: what if we could create a shopping experience with no lines and no checkout? Could we push the boundaries of computer vision and machine learning to create a store where customers could simply take what they want and go?” The company says on an informational page about Amazon Go. For now, Amazon is starting slow. The Amazon Go is only open to Amazon employees in our Beta program, and is scheduled to open to the public in 2017.

    Years ago, when I started looking for my first job, wise advisers urged, "Barbara, be enthusiastic! Enthusiasm will take you further than any amount of experience."

    How right they were. Enthusiastic people can turn a boring drive into an adventure, extra work into opportunity and strangers into friends.

    ''Nothing great was ever achieved without enthusiasm, wrote Ralph Waldo Emerson. It is the paste that helps you hang in there when the going gets tough. It is the inner voice that whispers, I can do it! " when others shout, "No, you can't."

    It took years and years for the early work of Barbara McClintock, a geneticist（遗传学家） who won the 1983 Nobel Prize in medicine, to be generally accepted． Yet she didn't let up on her experiments. Work was such a deep pleasure for her that she never thought of stopping.

    Author and poet Samuel Ullman once wrote, "Years wrinkle the skin, but to give up enthusiasm wrinkles the soul".

    Enthusiastic people also love what they do, regardless of money or title or power. If we cannot do what we love as a full-time career, we can treat it as a part-time interest, like the head of state who paints, the nun(修女) who runs marathons, the official who handcrafts（手工制作）furniture.

    We can't afford to waste tears on "might- have-beens". We need to turn the tears into sweat as we go after ''what-can-be".

    We need to live each moment wholeheartedly, with all our senses—finding pleasure in the fragrance of a back-yard garden, the crayoned（蜡笔的）picture of a six-year-old, the enchanting beauty of a rainbow. It is such enthusiastic love of life that puts a sparkle in our eyes, a lilt in our steps and smooths the wrinkles from our souls.

    On Monday, my classmates and I heard that our astronomy teacher's mother had died. We were surprised that he was still teaching in school. My best friend was telling me that the teacher was trying to forget the pain of losing his mother and trying to be strong in the middle of teaching.

    The teacher was such a warm-hearted person and we figured that we should give him a lot of love and good cheer. That night after school, my best friend and I thought about our teacher as well as his beloved mother and then we came up with an idea.

    When we went back to school yesterday, we gave him cheer-up cards which we had taken time to decorate with flowers, hearts and peace signs. As we handed the cards to him, we could both see the light in his eyes. The smiles on his face showed how much he appreciated what we did for him. The whole atmosphere was very warm and loving, and it's hard to express in words.

    This morning, when we both went to see the teacher again, he was so happy, and gave us both a hug. This made us feel that we just might have made his day, and that he was going to be okay.

    With that, I want to remind you to take the time to smile at the ones you love, be extra generous with hugs, kisses, things of that lovely nature! Life is so precious (宝贵的), so let us be happy and enjoy the gift of life.

    The world we live in gets more mechanized every year. Some countries which were mainly agricultural a hundred years ago have now become industrial. New factories and towns have been built on good agricultural land. There are now fewer farms to serve a much greater population, so these farms must be more efficient in order to produce as much food as possible. There is no place in the modern agricultural world for the inefficient farmer. Unfortunately, many of the picturesque aspects of farming are disappearing in the search for efficiency. The more tractors are used, the fewer horses are needed. Everyone agrees that horses are far more pleasant to look at than tractors. But they are less efficient. Cows are usually milked by machinery nowadays, and even pigs are fed automatically. There is not much art or poetry on the modern farm, and the old traditional idea of a farm as a slow, peaceful, romantic place is totally wrong nowadays.

    The modern farmer has to be a mechanic, a scientist, an accountant and a gambler. The more mechanized farming becomes, the more expert the farmer has to be. He must understand what machinery is necessary for his kind of farm, and he must know how to use it efficiently. He must also understand the new technical advances in agriculture, and how to use chemical and synthetic products to improve his crops. The more workers a farmer employs, the more he must know about the problems of wages and taxes. As in any other industry, most modern farmers find it necessary to employ office staff to deal with these. But although he has more modern equipments and far more scientific aids than his grandfather had, the farmer is still dependent upon the weather. As he can never be sure what the weather will do, he must be prepared to take risks, and face the possibility of losing everything.

    Age has never been a problem for 16­year­old Thessalonika Arzu­Embry. After all, she's already got her master's degree.

    The North Chicago­area teen started homeschooling at the age of 4. She began having an influence on others soon after. When she was 6 years old, she was an inspirational speaker at an organization called Tabitha House Community Service, a shelter for people who were forced to leave their homes due to the situations such as earthquake, flood and other natural disasters.

    At the age of 11, she graduated from high school and then earned her bachelor's degree in psychology in 2013. She completed those classes online as she was traveling for church events and leadership meetings.

    She doesn't stop there, though. The teen plans to focus on aviation psychology(航空心理学) for her further study, a decision inspired by her father who is a pilot. She grew up around airplanes and took fights all the time. Her goal is to use it to determine whether pilots are dealing with problems that could have deadly results once the plane takes off­a topic that has been in the news lately. For her, it's a mix of two of her interests.

    In her free time, Thessalonika enjoys playing tennis, swimming and being active in her youth group at church. She also has three self­published books, which are on her site. Jump the Education Barrier is written to help students finish college, and in the future aims to help business owners with trends. Her third book The Genius Race, has a wider appeal. It is designed to help people to be geniuses in various areas of life.

    Rock climbing is not just for grown-ups. Your children can also enjoy this fun-filled activity as well as getting its advantages. Aside from its heart-health benefit, it is also known to increase their self-confidence and esteem(尊重). While it may not be an impromptu(即兴的) activity like running or biking, there are many climbing walls that are now available, especially with the development of fitness centers and camps.

    The great thing about having your kids join these activities is that it follows up on their natural quality. As you know, children are natural climbers. You can see them going up on trees or climbing tall ladders. With rock climbing, you can satisfy their urges to be a climber.

    What's more, it is fairly easy for the kids compared with adults. With a high strength-to-weight rate, they have less body weight to pull up, and they are more flexible(灵活的).

    It is also a low-impact workout that tests your children's endurance(耐性). It's easy on their joints(关节) as they burn energy during their ascent. In addition, climbing walls are like giant puzzles begging to be solved. Not only does it test the physical aspects of your children's development, but it also wakes their mental abilities.

    This exercise also helps develop your children's essential strength and flexibility. Kids are challenged physically as they pull, lift, stretch, and twist their way up. This activity also develops their eye-hand coordination(协调) as they perform their climb.

    Almost anyone can do it although it may vary in skill level, namely beginner, intermediate, or advanced. But despite its reputation as an extreme sport, children can do this. One does not need to be super-fit to join a rock climbing class. However, good technique is more necessary than strength when doing this sport.
