Some people surveyed tasted the sweet, salty and crunchy together with other tastes of food as they listen to different noises.It shows that louder noises reduced the reported sweetness or saltiness of food while incr eatasing the measure of crunchiness（松脆）.

    It may go some way to explain Why airline food is widely complained about by both the workers and paddengers.Andy Woods,a researcher,said,“It's a general opinion that plane foods aren't fantastic,but I'm sure airlines do their best,so we wondered if there were other reasons,One thought was that perhaps the background noise may have an effect.NASA gives their space explorers very strong -tassting foods,because for some reason,they can't taste food that Strongly-^again, it may have something ti do with the background noise.”

    In a study ,48 people were fed sweet foods or salty ones, while listening tonoting or noise through earphone. Meanwhile they rated(划分等级) the foods. In noisier settings,foods were rated less or sweet than they were when it was silent,but were rated crunchier.“The evidence shows that if the background noise is loud, your food, attention might be drawn to that, away from the food.” Dr. Woods said.

    “We ae still at an early stage of progressing and this is a rather small  study to really draw definitive(最完整可靠的）conclusions from,” Dr. Woods said,“but they suggest that restaurants could well their choice of food for a given environment.”

    Also in the group's findings there is the suggestion that the overall satisfaction with the food is also related to the degree to which people like what they are hearing .

    A young woman sits alone in café sipping tea and reading a book. She pauses briefly to write in a nearby notepad before showing her words to a passing café waiter: “Where are the toilets please?” This is a familiar scene in Tokyo's so-called “silent cafes”, where customers are not allowed to speak, and only communicate by writing in notepads.

    The concept rises by a desire to be alone among young Japanese, a situation brought by economic uncertainly, a shift in traditional family support structures and the growing social isolation. The phenomenon is not limited to coffee shops but covers everything from silent discos, where participants dance alone wearing wireless headphones connected to the DJ, to products such as small desk tents designed for conversation-free privacy in the office. One Kyoto company even offers single women the opportunity to have a “one woman wedding” – a full bridal affair, complete with white dress and ceremony, and the only thing missing is the groom. The trend has its own media expression – “botchi-zoku”, referring to individuals who consciously choose to do things completely on their own.

    One recent weekday afternoon, Chihiro Higashikokubaru, a 23-year-old nurse, travelled 90 minutes from her home, to Tokyo on her day off in order to enjoy some solo time. Speaking quietly at the entrance of the café, Miss Higashikokubaru said: “I heard about this place via Twitter and I like the idea of coming here. I work as a nurse and it's always very busy. There are very few quiet places in Tokyo, and it's a big busy city. I just want to come and sit somewhere quietly on my own. I'm going to drink a cup of tea and maybe do some drawings. I like the idea of a quiet, calm atmosphere.”

    The desire to be isolated is not a new concept in Japan, home to an estimated 3.6 million “hikikomori” – a more extreme example of social recluses（隐士）who withdraw completely from society.

    It's a classroom. Instead of being told to sit quietly and listen, you are encouraged to stand up, jump around, imagine and act out. It's a class full of laughter and applause (鼓掌), emotion and energy. Welcome to drama class, one of my favorite classes at high school.

    In drama class we used to play a lot of “drama games”. We would improvise (即兴表演), copy and above all use our imagination.

    My favorite game was called “Spotto”. One person stood in the front of the class and performed a scene, completely out of their imagination. When one audience member yelled “Spotto!”, the performer had to freeze. Then the person who had yelled Spotto had to get up and improvise a new scenario (剧情) based on the position the first performer froze in. This went on as more and more people were added to the scene. Eventually the entire class would have joined the scene. Then the performers would start to leave in reverse (颠倒的) order.

    It was a lot of fun, and a good test of everyone's imagination to see what they would come up with. Drama class at my school often involved a big performance at the end of the term as well. We would work on a production throughout the term and put on a show for our parents and the school community.

    It was a great experience to perform on stage in front of a large audience. Drama class can help shy children, like me, to come out of their shells. It helped them become more confident and developed their public speaking skills. Drama class is also a great place to express oneself, and a way for children to use up some of their energy.

    Now many young people are traveling around the world on their own，not because they have no one to travel with，but because they prefer to go alone.

Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

    In foreign countries，with no one to help you read a map，look after you if you get ill，or lend you money if your wallet is stolen，it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

    Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website，The Aussie Nomad，to document his adventures. He says he wished he had traveled alone earlier. “The people you meet，the places you visit，or the things you do，everything is up to you and it forces you to grow as a person，” said the 30-year-old man.

    Richardson describes traveling alone like "a shot in the arm"，which "makes you a more confident person that is ready to deal with anything". He said，"The feeling of having overcome something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

    The great 19th century explorer John Muir once said，"Only by going alone in silence can one truly get into the heart of the wilderness."

    The Shiants, remote, cliff-edged islands off the coast of Scotland are home to 350,000 seabirds. This is the starting point for National Geographic contributor Adam Nicolson's new book, The Seabirds Cry. Celebrating 10 species in detail, he describes the unbelievable recovery of seabirds and the many adaptations that have enabled them to survive and navigate the oceans, while sounding a loud call for their conservation among severely falling numbers.

    Speaking from his home in Sussex, England, Nicolson explains why guillemot (海雀) colonies are information exchange centers: how new research is showing that those long-distance travelers. The shearwaters, "smell" their way across the globe; and what we can do to support seabird populations.

    National Geographic has just kicked off Year of the Bird with a cover story by Jonathan Franzen titled "Why Birds Matter ". The beginning of Year of the Bird is beneficial to birds. Nicolson said, "I'll ask you the same question-why? For me, these seabirds are symbols of uniqueness. There is so much on the land where the rest of the living world seems to be controlled by us, but when you go to seabird colonies, there is this pumping, loud and raging uniqueness. It's a glance of the untouched world. "

    "The reason why it's untouched is that, until recently, we have not controlled the oceans that the seabirds depend on. More of them have survived in greater numbers than most other creatures in the developed world, where huge amounts of the animal kingdom have been removed by us. And so one reason these birds matter is that they are symbols of what the world might be if we hadn't done so much damage to it. "He added.

    "Seabirds also tend to disappear; they're not reliably of our world, due to their migration and habits of life. Very deep in our consciousness is a sense that they are ambassadors from another world. And witnessing and feeling that is, I think, one of the great enlargers of life." Nicolson explained.

    This year promises to be an exciting one for technology and science. There's a line-up of great products for you to look forward to.
