Most drinks stating that they are fruit­flavored (水果味道的) 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 (标签) 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 colors, flavors, or sweeteners, but it contained absolutely 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. The products which contain real fruit are popular with people.

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

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

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

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

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

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

    Airbags, now found in almost every vehicle, have saved countless lives and largely reduced the severity of injuries in crashes. Similar technology could greatly reduce broken hips (髋部) resulting from a fall, something most seniors fear.

    Dr. Robert Buckman and his start-up company, Active Protective in Allentown, Pennsylvania, has developed a promising solution, a wearable airbag that can protect hip bones in the event of a fall. The idea was the result of Dr. Buckman's years as a doctor at Temple University. He noticed how many elderly people were being brought into hospitals with broken hip due to falls, and how they often never completely recovered from the injuries. He started to ask what he could do for these people, and that was when he started trying to figure out whether there was a way of helping people who were at the highest risk of falling and suffering these kinds of injuries.

    The device is worn much like a regular belt, but on the outside of the clothing, and it includes sensors that monitor the movement of hips. If the device detects that the person, is falling, an airbag opens before the person hits the ground, cushioning the fall. When the wearer hits the ground, the bag reduces the force to the hip bones by 90 percent, enough to avoid the majority of hip injuries.

    With one out of every three people aged 65 and older suffering serious falls each year, Active Protective has a big market for its wearable device. It also has the potential to sizably reduce hip - related health care expenses: Hip injuries among the elderly cost the US health care system in 2012 $30 billion, which doesn't include the long-term care expenses associated with the high percentage of patients that can no longer live independently.

We are interested in the preservation of the biodiversity on Earth. What I've been working on is rats. Just looking at rats, you can understand continental drift and climate change. We've actually rediscovered rats that were thought to be extinct. Darwin was the last one to document them on the Galapagos Islands. People have gone there for hundreds of years and not seen one. In 1997, I went there with my mentor(导师) and another graduate student. Everyone thought I was crazy, why look for something that doesn't exist? They wouldn't even give us permits. Our plan was to stop on a beach for a day and then hike up to the top of an extinct volcano where very few people had been: We were on a picturesque, isolated beach. We set out the traps just to see what we might find. The next morning, I checked my traps! I immediately ran back to my mentor. When he looked in the mental trap—I will never forget his face— It looked like he'd seen a ghost.

I certainly understand the argument: "Who cares about an extinct rat?" but you have no idea what role that rat plays in that functioning ecosystem. People can appreciate beauty, so that's why people love pandas and want to keep them around. You never hear, "What good is panda?" Ecologically, these rats are much more important to their ecosystem than those pandas— not that I don't love pandas but we have to look beyond the big and beautiful.

    I teach conservation biology and evolution. In both you have to appeal to people asking "Why is this important to me?" Some scientists refuse to do that. That's my entire approach. I'll ask "How many of you had a family member who was in a tornado, hurricane or flood?" .And almost every hand goes up. Climate change is suddenly very personal, and now they want to hear what you are saying. You are not looking for sympathy for the rats but for a greater understanding of the system.

    Although his 1-year-old smart-phone still works perfectly, Li Jijia already feels the need to replace it.

    "There are many better ones available now. It's time to upgrade(更新）my phone."

    Li's impatience is shared by many. Shortly after the season when new products are released（发布，发售）, many consumers feel the urge to upgrade their electronic equipment, even though the ones they have still work just fine.

    As consumers' minds are occupied by Apple's newly released products and debate whether the Google tablet is better than the new Amazon Kindle, it might be time to take a step back and ask: "Do we really need the latest upgrades?"

    According to Donald Norman, an American author, "planned obsolescence (淘汰）" is the trick behind the upgrading culture of today's consumer electronics industry.

    Electronics producers strategically release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version.

"This is an old-time trick—they're not inventing anything new," Norman said. "This is a wasteful system through which companies--many of them producing personal electronics—— release poor-quality products simply because they know that, in six months or a year, they'll put out a new one."

    But the new psychology of consumers is part of this system, as Norman admitted, "We now want something new, something pretty, the next shiny thing." In its most recent year, Apple's profit margin(利润) was more than 21 percent. At Hewlett-Packard, the world's biggest PC maker, it was only 7 percent.

    Apple's annual upgrades of its products create sales of millions of units as owners of one year's MacBook or iPhone line up to buy the newest version, even when the changes are slight.

    As to Li Jijia, the need for upgrading his smart-phone comes mainly from friends and classmates. When they are switching to the latest equipment, he worries about feeling left out.

    "Some games require better hardware to run," said Li. "If you don't join in, you lose part of the connection to your friends."

    Women in northern European nations are closest to equality with men on wages, education, health and education. That is the finding of a report by the World Economic Forum. The United States ranked 28th. On Friday, President Barack Obama announced the government will require large businesses to report how much they pay men and women. The data will be used to target companies that pay women less to do the same jobs.

    According to the World Economic Forum report, women worldwide continue to lag behind men on wages. Based on current trends, they will need 126 years to catch up, according to the report. Women are making progress. But they still only earn what men did 10 years ago, say the report's authors. The report measures the gender gap for women in 145 nations for health, education, economic opportunity, and political power. Women have not achieved equality in any of the 145 nations included in the survey, says the report.

    Women came closest to equality in four Northern European nations – Iceland, Norway, Finland and Sweden. Ireland ranks No. 5. At the bottom of the women's gender ratings are Yemen, Pakistan, Syria, Chad, Iran and Jordan.

    More women than men are attending colleges in 97 nations. But women make up a majority of skilled workers in only 68 nations. Women control the majority of government and political positions in only four.

    At last week's World Economic Forum in Davos, Switzerland, Sheryl Sandberg, chief operating officer at Facebook, spoke about gender equality. “The reason to work towards equality – whether woman or man – is that it is better for you,” Sandberg said. “We should be doing this not because it's the right thing, but because it's the smart thing. Do it because it will help you.” The World Economic Forum completed its worldwide 2015 gender gap survey in November.

Daphne Soares, a biologist, makes an amazing discovery about alligators. The first time she got really close to an alligator (短吻鳄) was when she was helping to bold down an eight-foot American alligator. It was then that she noticed is face was covered with little black spots. This led to the discovery of the little black dots.

She started her study of the black dots. When she read the books and scientific journals, she learned that people had noticed the dots, but no one really knew what the dots were for.

To find out the secret she placed electrodes (电极) on nerves coming from some of the dots. When the nerves fired, they sent a message to the brain and created a tiny electric current. Just then she heard a small sound over a loudspeaker. She tired to see if the dots acted like eyes and temperature sensors, but nothing worked.

One day she was careless with dropping a tool into an alligator's tank. When she put her hand in the tank to get the tool out, she made small waves in the water. When they reached the alligator's face, she heard a noise over the speaker. She then realized that the dots must be sensitive to the changes in pressure when hit by waves of water.

After that, she is now studying blind cavefish. She is trying to learn whether they are blind from birth or lose their sight as they grow up. She is also doing more research on crocodilians (鳄目). She wants to find out how the genes of alligators with pressure sensors only on their faces differ from the genes of crocodilians that have pressure sensors all over their body.
