Most drinks stating that they are fruit flavored contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.

    "Shoppers need to check the labels before buying drinks, though sometimes the actual content can be nonexistent," said Food Commission spokesperson Ian Tokelove. "Food production is highly competitive. {#blank#}1{#/blank#} It will increase profits, and consumers won't always realize they are being tricked."

    Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberryflavored products sold in stores.{#blank#}2{#/blank#} Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.

    {#blank#}3{#/blank#} Let's take jam as an example. Some strawberryflavored jam was labeled as containing no artificial color1 s, flavors, or sweeteners, but it contained ly no strawberries at all.

    {#blank#}4{#/blank#} Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. "Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading.{#blank#}5{#/blank#} Unfortunately, it is also legal and widespread," Tokelove said. "It's time to take measures to protect the consumers' rights."

A. They found that about 60 percent of them didn't contain any fruit at all.

B. Even products advertised as more natural often contained no fruit.

C. The products which contain real fruit are popular with people.

D. Actually the product contains just a tiny percentage of strawberry or even no fruit at all.

E. It is important and necessary to demand a small amount of flavoring in the products.

F. If companies can cut their costs by using flavoring, they are likely to do so.

G. The Food Commission suggested all flavors used in a product should be listed on the packaging.

    Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.

    “I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “I think by 2075 we will see it and that's a conservative estimate (保守的估计).”

    At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology (纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. “There is a great effort so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”

    However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.

    Scientists also differ on what kind of life the super aged might live. “It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Centre. “At present people who could get to that point are not in good health at all.”

    Dogs are wonderful companions all their own, but they can also help change your life so that you're more accepting of new friendships. A new study studied how dogs' brains responded to the human voice and found that “the human brain responds to dog emotions the same way it responds to human emotions” and that the dog's brain does the same.

    Dogs are pack animals, so in terms of pet ownership, your dog will prefer to stay with you rather than somewhere alone. Think about how this concept applies to friendship. People today are getting more and more used to spending time on social networking, email, and text. While all methods of communication are good, there is nothing like seeing your friends and hearing their voice. With good friends, sometimes a look explains everything, and you can only get this when you're together hanging out in person.

    Let's face it, dogs never hide their feeling. They let you know what they enjoy doing most, whether it is chasing a ball, going for a walk, or getting a treat. For people, it's harder to be open with your emotions. But in order to truly find a friend, you'll need to let go of your fears and put trust into your friends. The reality is that you'll never make everyone you meet happy one-hundred percent of the time, so if your friends and family think you're great, put aside the need to be liked by everyone.

    Dogs wait for you to come home and are so happy to see you again that they practically do a happy dance when you walk through the door. Friends, on the other hand, are sometimes so busy that even hearing from a friend becomes an unwelcome interruption. Rather than avoid calls or emails, make a point to talk to friends on a regular basis.

    Natural selection is the process by which one type of animal within a species thrives because of certain characteristics that make it more likely to live than others in its group. The history of the peppered moth（灰蛾）is an example of the natural selection process.

    In 19th century England, certain types of peppered moths were able to better blend（融合）into their surroundings. During that time period, great changes were happening in Great Britain. The Industrial Revolution was part of this change, and with it came air pollution. Natural selection often takes hundred or even thousands of years to occur. For the peppered moth, this process occurred comparatively quickly.

    At the beginning of the Industrial Age, most peppered moths in England were light-colored and covered with black markings, although a few moths had dark-colored wings. Because the light-colored moths blended into the light-colored bark on the trees, they could not be easily seen by birds that would eat them. As the air grew more polluted, however, tree trunks became covered with soot（烟煤）and became darker. The light-colored moths became easy for birds to see against the dark tree trunks. Since the dark-colored moths now had the advantage, their numbers grew. Within 50 years, the peppered moth went from being mostly light-colored to being mostly dark-colored.

    In the 20th century, the air cleared up, and the peppered moth population changed again. As tree trunks lighted due to less soot in the air, light-colored moths once again had an advantage. Their numbers increased as soot levels declined. Depending on their environment, the coloration of the moths helped them to be “naturally selected” to survive.

From an Alpine palace in Germany to some amazing English views, these dreamy destinations are so magical that it's hard to believe they're real.

    Gaudi's otherworldly imagination

    Designed by one of Spain's most famous architects, Antoni Gauldi, the Roman Catholic church Sagrada Familia is a legend in itself Construction began in 1882, but less than a quarter of the project was complete when Gaudi died in 1926. Since then, work has progressed slowly. How about the ending? Architects plan to complete the project in 2026, the centenary of Gaudi's death.

    As Barcelona's most popular tourist site, Sagrada Familia attracts three million visitors every year for one good reason: It's a masterpiece unlike anything else in the world which is largely responsible for the city's lively personality.

    A setting that could steal the spotlight from any storybook hero

    With its valleys surrounded by lakes, rivers, hills and peaks, the Lake District in England's northwest is quite literally taken out of fairy tales. This place was Beatrix Potter's inspiration for Peter Rabbit and the residence（居所）of the Lake Poets, including William Wordsworth, Samuel Taylor Coleridge and Robert Southey.

    One of nature's most magical illusions

    Once upon a time in the faraway land of the Faroe Islands, Lake Leitisvatn became known as the most striking of all the islands' lakes. At more than 6km long, it is the biggest in the Faroe Islands. In reality, Lake Leitisvatn is actually no more than about 30m above sea level. A steep cliff in front of the lake and a clever camera angle make the lake appear to be much higher than it really is.

    Whenever we see a button on a doorbell or on a remote, we may press it. This is true in most cases. But some buttons are actually fake(假的), like the "close" button on an elevator.

    Many people are in the habit of pressing the "close" button because they don't have the patience to wait for the elevator doors to shut. But according to experts, the buttons are a complete trick—the doors will not close any faster however hard you press.

    It started in the 1990s when the Americans with Disabilities Act was passed, making sure that all elevators stayed open long enough so that people with disabilities could enter. Only firefighters and maintenance workers(维修工) can use the buttons to speed up the door-closing process if they have a code or special keys. But to normal elevator riders, the buttons aren't completely useless.

    According to psychologists, fake buttons can actually make you feel better by offering you a sense of control. Experts have showed that a lot of buttons that don't do anything exist in our lives for this same purpose. For example, pedestrian crosswalk buttons don't live up to their names. Pressing them used to help make the traffic signals change faster, but that was before computer-controlled traffic signals were introduced.

    But psychologists found it interesting that even when people are aware of these little "white lies". They still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

    That habit is here to stay, John Kounios, a psychology professor at Drexel University in the US, told The New York Times. "After all, I've got nothing else to do while waiting. So why not try the chance?"
