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.

    Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time—about eight hours after you wake up—your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.

    In many parts of the world, people take naps (小睡) in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from problems such as heart disease. Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap—even ten minutes of sleep can be helpful.

Making Peace with Your Parents

    As a teen, you're going through big changes physically and mentally. Your interests are increasing.{#blank#}1{#/blank#}Here is the challenge: Kids need to explore the world in new ways, and parents need to protect them from the dangers that are all out in that world. These conflicts can easily set off fireworks in otherwise calm houses. Sometimes conflicts can't be avoided. But by paying attention to the building blocks of successful relationships, you can work towards making home a happy and healthy place for you and your parents.

    For example, try to find a time to talk when your parents are not angry, tired, distracted or hungry. A good time to talk is when you're all relaxed. Timing is everything if the conversation begins to turn into an argument, you'd better calmly and coolly ask to stop the conversation for now.{#blank#}2{#/blank#} Listen to what your parents are saying, and repeat it back to them. This shows them that you're listening. {#blank#}3{#/blank#} Respect is the building block of good communication. People who respect each other and care about each others' feelings can disagree without getting things ugly.{#blank#}4{#/blank#} How do you build trust? Trust comes by actually doing what you say you're going to do. Some teens find that doing fun activities with their parents can improve their relationships. Sometimes we forget that parents are more than rule-maker—they're interesting people who like to watch movies and go shopping—just like their teenagers!

    What do you do if you are trying your best, but your relationship with your parents continues to be rocky?{#blank#}5{#/blank#}You can find supportive adults, such as a teacher or a coach, who can lend an ear. Remember you can only change your own behavior. Your parents are the only ones who can change theirs.

A. You may consider seeking outside help.

B. And then you'll be able to accept what your parents say.

C. You can pick it up again when everyone's more relaxed.

D. Faced with the challenge, children don't know what to do.

E. And your desire to take control of your own life is growing.

F. It also gives them a chance to clear things up if you're not on the same page.

G. You are more likely to get along with your parents and have more independence if your parents believe in you.

    Nowadays it's believed that the largest contributors to air pollution are gasoline vehicles. They not only give off harmful gases but also dangerous and heavy metal particles（微粒） that can result in environmental dangers. We can't stop using vehicles and thus stop air pollution right away. However, at least we can look for better replacements so that air pollution can be reduced. According to studies, hydrogen （氢）cars prove to be a better replacement for traditional cars.

    A hydrogen car is a vehicle that uses hydrogen as fuel for its engine to work. There are two types of hydrogen cars. The first one is to use hydrogen as a fuel, and the second one is to use hydrogen fuel cells（电池） to provide power for the car. Hydrogen and oxygen react chemically with each other to produce electricity, thus starting the car.

    There are many advantages of hydrogen cars. For example, hydrogen is available in plenty. Therefore, you needn't worry about a lack of hydrogen. More importantly, no harmful gases are released as by-products .The only by-products are water and a little amount of heat so air pollution is prevented up to a large extent.

    However, there are also some problems with hydrogen cars. For instance, in case of damage, the cost of repairing and replacing fuel cells is high. Worse still, hydrogen is a material which can burn easily, so it can result in a huge explosion of the car.

    The concept of hydrogen cars is relatively new for most people. Research is still in progress to reduce disadvantages and increase advantages. Therefore, hydrogen cars are expected to contribute their bit towards making this planet better and healthier!

    The Intelligent Transport team at Newcastle University have turned an electric car into a mobile laboratory named "DriveLAB" in order to understand the challenges faced by older drivers and to discover where the key stress points are.

    Research shows that giving up driving is one of the key reasons for a fall in health and well-being among older people, leading to them becoming more isolated (隔绝) and inactive.

    Led by Professor Phil Blythe, the Newcastle team are developing in-vehicle technologies for older drivers which they hope could help them to continue driving into later life.

    These include custom-made navigation (导航) tools, night vision systems and intelligent speed adaptations. Phil Blythe explains: "For many older people, particularly those living alone or in the country, driving is important for preserving their independence, giving them the freedom to get out and about without having to rely on others.

    "But we all have to accept that as we get older our reactions slow down and this often results in people avoiding any potentially challenging driving conditions and losing confidence in their driving skills. The result is that people stop driving before they really need to."

    Dr Amy Guo, the leading researcher on the older driver study, explains:" The DriveLAB is helping us to understand what the key stress points and difficulties are for older drivers and how we might use technology to address these problems.

    "For example, most of us would expect older drivers always go slower than everyone else but surprisingly, we found that in 30mph zones they struggled to keep at a constant speed and so were more likely to break the speed limit and be at risk of getting fined. We're looking at the benefits of systems which control their speed as a way of preventing that.

    "We hope that our work will help with technological solutions (解决方案) to ensure that older drivers stay safer behind the wheel."
