Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels. However, if you think paying a little more for organic food gets you a more nutritious and safer product, then you'd better save your money. A study led by researchers at Stanford University says that organic products aren't necessarily more nutritious, and they're no less likely to suffer from disease-causing bacteria, either.
For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.
While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.
Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn't always translate into a more nutritious or healthier product. The U. S. Department of Agriculture(USDA) states that “whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

There are four main food groups altogether. The dairy group has food like milk, cheese and sour milk. The other three groups are the meat and fish group, the fruit and vegetable group, and the bread and rice group. Each meal should have at least one food from all four main groups. With all these food together, you will be given enough energy during the day.
It is easy to get into bad eating habits. You may eat your breakfast in a hurry to get to school on time. Or you may not have time for a good lunch. It may seem easy to finish your supper with fish and chips all the time. But you will find yourself tired in these days and you can not think quickly.
Watching what you eat will help keep your body healthy and strong. It is also good to take some exercise. It will help you eat more if you take a walk or play games in the open air. Having a good eating habit with some exercise is the key to your health.

【推荐2】Easy Habits That Help You Live Longer
♦ Go for a jog
Among all the things you can do to achieve longevity, one of the most critical is to exercise. Aerobic activity, like running, is important for getting your blood pumping and your heart working. A recent study showed that a one-hour run adds seven hours to your life, up to four hours per week. People who run have a 25 to 40 percent reduced risk of early death, and live about three years longer.
♦Get more sun—but not too much
The “Sunshine vitamin” -vitamin D, that is-has been shown to fight disease, improve bone health, and avoid depression. One study even found it to extend lifespan by 33 percent. But because vitamin D comes from the sun, and our modem lives don't let us spend much time outside, we might not be getting enough. Getting 15 to 30 minutes of sun exposure a day should be enough for vitamin D production.
♦ Eat more plant protein
A recent study from Harvard found that people who ate a diet high in processed meats like ham, were at a higher risk of death—but those who got their protein from plants had a lower risk, especially of heart disease-related deaths. The study said that for every three percent increase in calories from plant protein there was a reduction in risk of death by 10 percent.
♦Eat nuts
Although you may think nuts are unhealthy because they are calorically high, the exact opposite is true—they can actually extend your life. A study from Harvard found that daily nut-eaters were 20 percent less likely to die during the study. Specifically, the rates of death from heart and breathing disease were reduced. Other research has shown walnuts have a huge role in heart health because of the amount of antioxidants (抗氧剂)they contain.

【推荐3】It’s one of the ultimate tests of willpower: you’ve been wandering around the market for hours and you’re tired and hungry. Then you catch a smell of something fragrant (香的) and delicious, probably fried and almost certainly fattening. Junk food companies are well aware that the smell of their product sets off a desire in your brain and that you’ll pay for that later. It is a response that has been researched, and you’d better believe your favorite fast-food chains have marketing teams that are using that research to their advantage.
Let’s take a closer look at this process. Have you ever noticed that whatever indulgent food (放纵型食品) catches your attention tends to be most appealing just after you first smell it? A couple of minutes later you are standing in line, and it isn’t quite inviting as it was just moments ago, but now you’ve invested time, so you trust your first feeling to treat yourself.
But a recent statement says that this is actually the right moment to walk away. Dipayan Biswas, a marketing professor, found there is a direct connection between how long a person is exposed to indulgent food smells and choosing healthier foods. “The results of a series of experiments show that extended exposure of more than two minutes to junk food smells leads to fewer purchases of unhealthy foods compared with no smell or a non-junk-food-related smell,” reads the summary of his study.
What appears to be going on here is that the brain doesn’t necessarily distinguish between a pleasurable smell and a pleasant taste. “Extended exposure to an indulgent food smell brings pleasure in the mind, which in turn reduces the desire for actual consumption of indulgent foods,” he explains. So next time you feel you don’t have the willpower to resist cookies, smell all that sweetness for just a minute or two. To your brain it’s the same as actually eating cookies, and the purchase desire would decrease.
1. What can we learn about junk food smells from the first paragraph?A.They can make a difference in marketing. |
B.They hardly affect people’s food choices. |
C.They are unlikely to fool wise customers. |
D.They finally decrease people’s purchase desire. |

A.The brain can’t tell where sensory pleasure is from. |
B.The senses of taste and smell are closely linked. |
C.The influence of food smells changes over time. |
D.The behavior of smelling food doesn’t equal eating it. |
A.Train Your Brain to Resist Junk Food |
B.Watch Out for Tricky Marketing Tools |

【推荐1】Thousands of years have passed since humans discovered silk, but scientists are still finding new uses for this remarkable material. Now researchers say it could help tackle a growing environmental and health concern: Micro-plastics.
Micro-plastics that are now found worldwide are increasingly recognized as a serious pollution threat, and have been found in the bloodstream of animals and people. Some of these micro plastics are intentionally added to a variety of products to generally protect some specific active components from being degraded by exposure to air. For example, vitamins are often delivered in the form of micro capsules packed into a pill or capsule,and herbicides(除草剂)are similarly enveloped. But the materials used today for such micro-encapsulation are plastics that stay in the environment for a long time. To date, there has been no practical, economical alternative available that would biodegrade naturally.
Researchers at the Massachusetts Institute of Technology and chemical company BASF developed a silk-based biodegradable alternative to these capsules.
Silk is recognized as safe for food or medical use, as it degrades naturally in the body. The silk protein used in the new alternative material is widely available and inexpensive and the silk fibers can simply be dissolved(溶解), lead researcher Benedetto Marelli says. Besides, the processing is so simple and tun-able that the resulting material can be adapted to work on existing manufacturing equipment.
Replacing non-biodegradable micro-capsules with silk might not work in every case,but given the current and future challenges related to food insecurity, agricultural production, and a changing climate, the silk-based material is of great importance. Products using silk-based micro-capsules are expected to be commercially available in a few years. And the researchers will next try encapsulating active components that could require a different manufacturing approach, such as those that must remain in liquid or gas forms.

【推荐2】Darrell Blatchley,a marine biologist and environmentalist based in the Philippine city of Davao,received a call from the Philippine,Bureau of Fisheries and Aquatic Resources(渔业与水产资源局) early Friday morning reporting a death of a young whale.
When the necropsy(尸检) was performed,Blatchley told NPR,he was not prepared for the amount of plastic they found in the whale’s stomach.“It was full of plastic nothing but nonstop plastic,” he said.“It was filled to the point that its stomach was as hard as a baseball.That means that this animal has been suffering not for days or weeks but for months or even a year or more,” Blatchley added.
Blatchley is the founder and owner of the D’Bone Collector Museum,a natural history museum in Davao.In the coming days,the museum will display all the items found in the whale’s system.Blatchley and his team work with the Bureau of Fisheries and Aquatic Resources and other organizations to assist in rescue and recovery of marine animals.
“Within the last 10 years,we have recovered 61 whales and dolphins just within the Davao Gulf,” he said.“Of them,57 have died due to man whether they took plastic or fishing nets or other waste,or gotten caught in pollution—and four were pregnant.”
Blatchley said he hoped that the latest incident would launch the issue of plastic pollution in the Philippines and across the globe.“If we keep going this way,it will be more uncommon to see an animal die of natural causes than it is to see an animal die of plastic,” he said.

【推荐3】As both a parent and a college professor, I have witnessed the destructive effects of test anxiety. Students with it can say quickly the material and explain complex content in a relaxed environment but fail in an exam. When it matters the most, students with test anxiety can convey the least.
Some students turn to drugs. With any medicine, there is a concern for safety, particularly when it is with the brain, the body’s most complicated and important organ. A new study suggests there may be a choice to these drugs for students: an open-label placebo (安慰剂).
Placebos have long been known to effectively reduce symptoms for different illnesses. Traditionally, service of a placebo treatment requires some tricks, in that people believe they are receiving an active, effective treatment, but in reality, they are taking a sugar pill or an activity that has no medical help. An open-label placebo is different: people are told from the start that they are receiving a placebo that contains no medication. And yet Schaefer’s findings indicate that people may still benefit from it.
Why did the placebo work? At this point, scientists are not entirely sure. Human mental processes can be changed by environment. Taking the pills each day may have encouraged participants to think about test anxiety and may have also provided a sense that they were doing something to deal with it.
Finally, although participants taking the placebos did show improvement on a number of self-report measures, they had no benefit over the control group with respect to scores on their final exams. They may have felt better about taking their exams, but those feelings did not change into improved test scores.
Despite these limits, the present findings are appealing and suggest a low-cost, low-risk way for reducing an all-too common problem among students.

【推荐1】Nao, the first robot able to show feelings, has been created by a European research team. When Nao is sad, he lowers his head and looks down. When he’s happy, he raises his arms for a hug. Nothing is out of the ordinary, except that Nao is a robot.
“We’re modeling the first years of life,” says Lola Canamero, a computer scientist at the University of Hertforshire. “The feelings are shown through physical gestures and body movements rather than facial or verbal (言语的) expressions.”
In the future, says the scientist, robots are likely to act as companions, provide support for old people, and help people shop online. In such uses, the display of feeling will be important in making the interactions (交往) more natural and comfortable.
Nao has been programmed to copy the emotional skills of a one-year-old child. It can memorize faces, and knows the basic rules of good and bad. Based on these it can decide how to react to what is going on. The actions going with each feeling are pre-programmed, but Nao decides for itself when to display them.
Nao is also programmed to have different personalities. A more independent robot is less likely to call for help when exploring a room, while a more fearful robot will show distress if it finds something in the room that may be harmful.
Canamero’s team will take its emotional programming forward into medical applications. Part of the project will look at ways to use robots in hospitals to support the roles of doctors, nurses and parents. Children might find that a small, friendly-looking robot that can understand their emotional states makes them less anxious. “We want to explore different roles—the robots will help the children to understand their treatment and explain what they have to do. We want to help the children to control their anxiety.” she says.

【推荐2】The public nowadays has a misunderstanding of forest fires, believing that fires should be kept out of every type of forest. Many of us can recall Smoky the Bear's famous warning: “Remember, only YOU can prevent forest fires”. However, that's not always the case. Under the right conditions, and when conducted safely, fire can create many environmental benefits as well as help prevent larger, uncontrollable wildfires.
After a forest fire, many wildlife species will move into recently burned areas to feed on these newly available foods. Some reptiles and amphibians such as the pine (松树) snake prefer forests frequently burned by fire. As Herbert Stoddard put it, “One of the most harmful things modern man has done to birds has been his attempt to exclude fire from fire-type pine forests. Within a few years most forests choke up with bushes, lose their prairie-like vegetation (草原般植被) and can no longer support birds dependent on periodic burning for their food supply and proper cover.”
If you are asked to picture the forest floor, what do you see? Pine needles, cones, leaves, branches might come to mind-all sources of fuel. If these fuel sources build up without any type of removal, the 'fuel load' can lead to fires catastrophic to forests and people alike. In contrast, prescribed fire can be used by forest professionals every couple of years to keep forest fuels at an appropriate and manageable level. They can also minimize the spread of pest insects and disease and remove unwanted tree and plant species. Plus, they can create and maintain important wildlife habitats rich in grasses and promote the growth of trees, wildflowers and other various plants.
Many organizations and agencies work to promote fire on the landscape when and where appropriate. Smokey Bear even has an updated warning: “Only You can Prevent Wildfires,” as the Forest Service has over the last few decades developed policies and procedures to include prescribed fire as a management tool, as well as continuing their work to prevent and fight wildfires.

【推荐1】I was shocked at the news that Daisy-May Demetre, 9, became the first child double amputee(截肢)to walk on the runway at New York Fashion Week in September on the top of the Eiffel Tower.
Daisy-May, of Birmingham, was born with fibular hemimelia (腓骨半肢畸形).The condition is rare, occurring in 1 in 50,000 births. When she was 18 months old, Daisy-May's parents chose to have both of the young girl's legs amputated-the right above the knee and the left below the knee-in the hopes of giving her a better quality of life with prosthetics(假肢).Later on, she used prosthetic legs to help her walk and move.
“We had the choice for her to live like that or to go for the operation,” Alex, Daisy- May's father, said. “We didn't know at the time that Daisy-May would be as good as she is now. Instead of being discouraged by prosthetic legs, she is inspiring everyone by showing them who she is.”
She is, in many ways, just like any fifth-grader.、In school, she prefers English over math, and loves gymnastics. She is a gymnast as well as a model. But it's her moves on the runway that shed the most confidence.
She's been modeling for 18 months and has already dominated London Fashion Week, having worked. for Nike, River Island and several other high street brands in the UK. She was even named Child of Courage in the Pride of Birmingham Awards for inspiring other children to dream big in the face of immense challenges.
In the opinion of Daisy-May's father, modeling doesn't define Daisy-May. Rather, it's a small part of who she is. She just does Daisy. It is the way she goes about life with a smile on her face. Whether it's dancing, singing-she is a very special little girl.

【推荐2】I’m May. high school seniors all around the U. S. scramble (争抢) to get ready for prom. Prom. short for promenade, is a formal dance held by a high school before graduation. It's an important aspect of American school culture because it's the last high-school dance seniors will ever attend.
Prom entails (牵涉) countless traditions. First a guy must ask a girl to go to prom with him. Most guys choose to do special prom proposals in hopes of winning the girl's heart with their creativity. Then he will rent a tuxedo (燕尾服), and the girl will often get their hair, nails and makeup done professionally. That night couples will take pictures, and then they will often take a limousine (豪华轿车) to dinner and to the dance. Several reports state that parents can spend upward of $ 2,000 to give their kids the perfect prom experience.
The history of prom can be traced back to the last half of the 1800s. At that time, American universities and colleges organized dances each year for their graduating students. The purpose was not only to entertain the students but also to prepare them for the wider world by teaching them proper manners for men and women.
Later, high schools took over the prom tradition. In the 1950s, high schools began moving the dance from their gyms to beautiful hotels or country clubs to make the event even more special. Perhaps the most amazing prom took place in 1975, when Susan Ford, the daughter of the country's president, received permission to hold her high school's prom at the White House. So far, no other prom has managed to top that.

Rick is disabled and during Ironman Triathlons (铁人三项赛)Dick pulls Rick in a special boat as they swim, carries him in a special seat in the front of a bicycle as they ride, and pushes him in a special wheelchair as they run.
This love story began when Rick was small. Doctors told the Hoyts the boy would be a vegetable for the rest of his life, but the Hoyts weren't accepting it. They noticed the way Rick's eyes followed them around the room. Years later, the Hoyts took Rick to Tufts University and asked if there was anything to help the boy communicate. "No way." Dick was told, "There's nothing going on in his brain.” "Tell him a joke. " Dick replied. They did. Rick laughed. It turned out a lot was going on in his brain. With the help of a special computer, Rick was finally able to communicate.
Rick told his father through the computer that he wanted to join a charity run. Dick didn't want to disappoint Rick, so he tried to push his son five miles. That day changed Rick's life. "Dad," he typed, “when we were crazy running, it felt as I wasn't disabled anymore !" And that sentence touched Dick so much that he became crazy for giving Rick that feeling as often as he could.
