    Supermarkets are trying out new computers that make shopping carts more intelligent(具备智能的). They will help shoppers find paper cups or toilet soap, and keep a record of the bill.

    The touch-screen devices(触摸屏装置) are on show at the Food Marketing Institute's exhibition here this week, "These devices are able to create value and get you around the store quicker," said Michael Alexander, manager of Springboard Retail Networks Inc., which makes a smart cart computer called the Concierge.

    Canadian stores will test the Concierge in July. A similar device, IBM's "Shopping Buddy", has recently been test-marketed at Stop & Shop stores in Massachusetts.

    Neither device tells you how many fat grams or calories are in your cart, but they will flash you with items on sale. The idea is to make it easier for people to buy, not to have second thoughts that maybe you should put something back on the shelf.

    "The whole model is driven by advertisers' need to get in front of shoppers," said Alexander. "They're not watching 30-second TV ads anymore."

    People can use a home computer to make their shopping lists. Once at the store, a shopper can use a preferred customer card to start a system(系统) that will organize the trip around the store. If you're looking for toothpicks, you type in the word or pick it from a list, and a map will appear on the screen showing where you are and where you can find them.

    The device also keeps a record of what you buy. When you're finished, the device figures out your bill. Then you go to the checker or place your card into a self-checkout stand and pay.

    The new computerized shopping assistants don't come cheap. The Buddy devices will cost the average store about $160,000, and the Concierge will cost stores about $500 for each device.

(1)、The underlined word "they" (paragraph 1) refers to ______.
A、supermarkets B、shop assistants C、shopping carts D、shop managers
(2)、Which of the following is the correct order of shopping with computerized shopping carts?

a. Start the system.       b. Make a shopping list.

c. Find the things you want.  d. Go to a self-checkout stand.

A、abdc B、bacd C、acbd D、bcad
(3)、We can learn from the last paragraph that ______.
A、intelligent shopping carts cost a large sum of money B、the Concierge is cheaper than the Buddy devices C、shop assistants with computer knowledge are well paid D、average stores prefer the Concierge to the Buddy devices
(4)、What might be the most suitable title for the text?
A、New age for supermarkets B、Concierge and Shopping Buddy C、New computers make shopping carts smarter D、Touch-screen devices make shopping enjoyable

         If you could have one superpower, what would it be?

          Dreaming about whether you would want to read minds, see through walls, or have superhuman strength may sound silly, but it actually gets to the heart of what really matters in your life.

         Every day in our work, we are inspired by the people we meet doing extraordinary things to improve the world.

         They have a different kind of superpower that all of us possess: the power to make a difference in the lives of others.

We're not saying that everyone needs to contribute their lives to the poor. Your lives are busy enough doing homework, playing sports, making friends, seeking after your dreams. But we do think that you can live a more powerful life when you devote some of your time and energy to something much larger than yourself. Find an issue you are interested in and learn more. Volunteer or, if you can, contribute a little money to a cause. Whatever you do, don't be a bystander. Get involved. You may have the opportunity to make your biggest difference when you're older. But why not start now?

        Our own experience working together on health, development, and energy the last twenty years has been one of the most rewarding parts of our lives. It has changed who we are and continues to fuel our optimism about how much the lives of the poorest people will improve in the years ahead.

         Before birth, babies can tell the difference between loud sounds and voices. They can even distinguish their mother's voice from that of a female stranger. But when it comes to embryonic learning(胎教), birds could rule the roost. As recently reported in The Auk: Ornithological Advances, some mother birds may teach their young to sing even before they hatch(孵化)。New-born chicks can then imitate their mom's call within a few days of entering the world.

    This educational method was first observed in 2012 by Sonia Kleindorfer, a biologist at Flinders University in South Australia, and her colleagues. Female Australian superb fairy wrens were found to repeat one sound over and over again while hatching their eggs, When the eggs were hatched, the baby birds made the similar chirp to their mothers—a sound that served as their regular “feed me!”call.

To find out if the special quality was more widespread in birds, the researchers sought the red-backed fairy wren, another species of Australian songbird. First they collected sound data from 67 nests in four sites in Queensland before and after hatching, Then they identified begging calls by analyzing the order and number of notes. A computer analysis blindly compared calls produced by mothers and chicks, ranking them by similarity.

    It turns out that baby red-backed fairy wrens also emerge chirping like their moms. And the more frequently mothers had called to their eggs, the more similar were the babies' begging calls. In addition, the team set up a separate experiment that suggested that the baby birds that most closely imitated their mom's voice were rewarded with the most food.

    This observation hints that effective embryonic learning could signal neurological(神经系统的) strengths of children to parents. An evolutionary inference can then be drawn.“As a parent, do you invest in quality children, or do you invest in children that are in need? ”Kleindorfer asks. “Our results suggest that they might be going for quality. ”

    The stories we share with one another are important. They show wisdom and provide inspiration. They are important to our development. But sometimes people choose not to tell.

    Considering the negative effects of not sharing a story in the news, people are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.

    There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, “The fact is, history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When they are finally uncorked(透漏), their power to destroy is set free."

    There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret—especially those that embarrass someone else.

    Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.

    Honesty and openness is important: It proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard work, we do not have to be restricted to our mistakes.

    Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in an appropriate manner.

    Many people trying to sell homes find that an increase in home prices has turned the market in their favor. But sellers can still get the short end of the deal if they aren't careful. Here are a few tips for you:

    Don't test your luck. Of course you think anyone who moves into your lovely home should be willing to pay top dollars, especially if you've recently invested in some improvements. But listing a home at a price that's too high above the market price could turn away some buyers.

    Buyers noticing that the home still hasn't sold may begin to assume there's something wrong with the house and use that as a reasonable excuse for offering a lower price. And if a home hasn't received any offers after two weeks, it might be time to reset the price.

    A price that's too low can bring about an undesired outcome. Listing your home at or slightly below the market price can have the effect of drawing in a large group of buyers and increase the chances that a home will receive multiple offers. But setting the price too low comes with several risks. One possibility is that buyers will get skeptical of the home that is listed for $ 15,000 to $ 20,000 less than similar homes in the area, especially if it's not properly marketed. Once again, people might assume there is something wrong with the home and may not bother to look at it.

    Spy on the competition. Going to other people's open houses can give you a better sense of how your home compares to others on the market. Check out the decoration in their kitchens, the size of their backyards and use the information to figure out where your home should fit in the range of the price. But don't set your pricing just on what you see elsewhere.

    A new study has found that social media could be affecting the sleep of young adults.

    The study is a project of researchers at the University of Pittsburgh's School of Medicine. They found that young people who often use social media are more likely to suffer from sleep disorders than those who use social media less. The researchers say doctors should ask young adults about their use of social media when treating sleep issues.

    "This is one of the first pieces of evidence that social media use really can influence your sleep." said Jessica C Levenson. She was the lead author of a report on the study.

    The researchers set out to examine the connection between social media use and sleep among young adults. Levenson noted that these young adults are possibly the first "generation to grow up with social media."

    The researchers wanted to find out how often young people used social media sites like Facebook, Twitter, Credit and Tumbler. For the study, they gave questionnaires to nearly 1,800 adults, aged 19 to 32. On average, members of the study group used social media sites one hour a day. They also "visited various social media 30 times per week."

    Thirty percent of the study's participants reported having serious problems with sleeping. Those people who used social media a lot were three times more likely to have a sleep disorder. And those who spent the most time on social media were two times as likely to suffer from sleep disturbances.

    Levenson said the number of times a person visits social media is a better predictor of sleep problems than overall time spent on social media. If this is true, she adds, then practices that stop such behaviors may be the most effective.
