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.

Live in Cave

    Kokopelli's Cave Bed &Breakfast, Farmington, New Mexico.

    The idea may seem very stone age, but this lone unit, which was carved into a 65-million-year-old sandstone rock, is filled with modern amenities(便利设施). The Travel Channel says these “cave comforts” include a comfortable bedroom, large fire circle, and rainfall shower. Plus, the views of the La Plata River and nearby mountains are breathtaking.

    As I was thinking about language learning the other day, the image of baking bread came into my mind. I compared some of the exercises and drills that we put ourselves through in order to learn a language to the various ingredients that go into baking a loaf of fresh bread.

    Real language learning takes place in human relationships. No one sits down and eats a cup of flour, even if he is hungry and in a hurry. You don't become bilingual（双语的）by learning lists of vocabulary. You don't become a speaker of a language by memorizing verb conjugations（动词的词形变化）and agreement rules. You become bilingual by entering a community that uses that other language as its primary means of communication.

    I am not suggesting that we can make bread without ingredients. Flour is necessary, as are yeast, salt, water and other ingredients. Vocabulary is part of any language and will have to be learned. Grammatical rules exist in every language and cannot be ignored. But merely combining the appropriate ingredients in the recommended proportions does not result in bread. At best, you only end up with a ball of dough（面团）.

    In order to get bread, you have to apply heat to the dough. And in language learning, that heat comes from the community. Anyone who has learned a second language has experienced that heat. It creeps up your neck when you ask the babysitter, “Have you already been eaten?” when you meant to say, “Have you already eaten?” When you try to say something quite innocent and the whole room bursts into laughter, you are experiencing the heat that turns raw dough into good bread.

    Remember the old saying, “If you can't stand the heat, get out of the kitchen”? This is where language learning often breaks down because we find the heat uncomfortable and we stop the baking process. In other words, we can't stand the heat, so we get out of the kitchen.

    However, the language learner who stays in the kitchen—in the heat—until the combined ingredients are thoroughly transformed will enjoy the richness of a quality loaf of bread. He said that he did not “get out of the kitchen” at the critical moment when the oven seemed too hot. The dedicated language learner knows that becoming bilingual cannot be achieved without the heat!

    Four books that will inspire you to travel the world

    There's truly nothing like travel when it comes to gaining perspectives and exposing yourself to other cultures. To get you in the adventuring mood, we asked Amazon Senior Editor Chris Schlep to help you come up with a list of books that transport readers to another time and place. Below, see his list of four books that will inspire you to travel the world.

    ITALY: Beautiful Ruins by Jess Walter

    This book by the popular author Jess Walter is a love story that begins on the Italian Coast in the early 60s and eventually concludes in contemporary Hollywood's screen. As the settings shift from Italy to Edinburgh and Los Angeles, you will find yourself longing to go as well. Buy it on Amazon. Price: $28.90

    SEATTLE: Where'd You Go, Bernadette by Maria Semple

    Maria Semple's first novel is not exactly a love story in Seattle, but if you read it, you just might want to come here to see if people are really as self­involved as the characters in her book. What really shines through is the strange storytelling and the laughs. Buy it on Amazon. Price: $26.60

    ENGLAND: Wolf Hall by Hilary Mantel

    You can't travel to Thomas Cromwell's England without a time machine, but reading Mantel's prize­winning novel is the next best thing. It will make you long to see the ancient buildings and green grass of the English countryside, most of which are still there. Buy it on Amazon. Price: $25.10

    NANTUCKET: Here's to Us by Elin Hilderbrand

    Elin Hilderbrand has built a writing career out of writing about her hometown island of Nantucket. Her latest book is Here's to Us, which, perhaps not surprisingly, is a great beach book. Buy it on Amazon. Price: $30.80

    We discuss the issue of when to help a patient die, which was not talked about openly and little was written about it.

    The best way to bring the problem into focus is to describe two patients whom I cared for. The first, formerly a nurse, had an automobile accident. And there she was: in coma, on a breathing machine. One day, her husband and son came to see me. They told me their wife and mother was obviously going to die; she was a nurse and had told her family that she never wanted this kind of terrible death, being maintained by machines. I told them that while I respected their view, there was nothing deadly about her situation. The kidney(肾) failure she had was just the kind for which the artificial (人造的) kidney was most effective. While possibly a bit reassured, they were disappointed. Here was the head surgeon seemingly determined to keep everybody alive, no matter what.

    Within a few days the patient awoke from her coma. About six months later, the door of my office opened and in walked a gloriously fit woman. After some cheery words of appreciation, the father and son asked to speak to me alone. As soon as the door closed, both men became quite tearful. All that came out was, "We want you to know how wrong we were."

    The second patient was an 85-year-old lady whose hair caught fire while she was smoking. She arrived with a deep burn; I knew it would surely be deadly. At the time, there was a class discussing medical ethics(道德). The instructor asked me if I had any sort of ethical problem I could bring up for discussion. I described the case and asked the students their opinion. After the discussion, I made a remark that was, when looking back, a serious mistake. I said, "I'll talk with the nurses before we decide." The instructor and the students were shocked: "You mean this is a real patient?" The teacher of ethics was not accustomed to being challenged by actuality.

    A day or two later, when the lady was making no progress and was suffering terribly, we began to back off in treatment. Soon she died quietly and not in pain. As a reasonable physician, you had better move ahead and do what you would want done for you. And don't discuss it with the world first. There is a lesson here for everybody. Assisting people to leave this life requires strong judgment and long experience to avoid its misuse.

How to Bring Our Community Together

Canada is a nation that prides itself on multiculturalism and the opportunity. {#blank#}1{#/blank#} Building social connections and a sense of belonging brings people together in ways that strengthen individual relationships as well as the whole community.

There are several things that we can do to develop strong social connections and a sense of belonging :

{#blank#}2{#/blank#} One of the simplest ways to bring a community together is through shared experiences. Events like an international food festival, a sports league featuring activities from around the world, and health and wellness programs drawing on different cultures, are excellent ways of bringing people together.

Think outside the box. {#blank#}3{#/blank#} Many of us get caught up in our own routines and practices and forget that there are other ways of doing things. Try talking to different community members, ranging from youths to seniors, to understand their opinions of the world. {#blank#}4{#/blank#} .

Try new things. Positively influencing our community can go beyond volunteering our time and resources.

Consider getting involved in our community by working for the 2017 Census(人口普查)as an enumerator (普查员) or a crew leader. Census enumerators are responsible for identifying dwellings on maps, conducting personal interviews, and following up respondents in person and by phone, while crew leaders are responsible for leading, training and supervising a team of enumerators. {#blank#}5{#/blank#}.

A strong feeling of unity in a community can make residents feel comfortable and at home.
 

A. Plan community events.

B. Encourage community members to do some community service work.

C. Social connections offer community members chances to know each other better.

D. Our multicultural tradition provides a welcoming environment for individuals and families.

E. Learning about different cultures and practices can open our mind to a whole new way of life.

F. Invite individuals of different cultures to participate in community planning to ensure that every voice is heard.

G. These positions provide an opportunity to meet new people and build relationships with members of our

community.
