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 .

    India has many festivals, with some celebrations that last for weeks. However, none of them come even close to Holi, India's most colorful and fun festival. Celebrated on the day following the full moon, this year's festival happens to be on March 19th.

    As with most Indian festivals, this one also has many different folk stories. Most of them center around the success of good over evil. The most popular one is about a king, who hates his son Prahlada for loving the creator of the Universe－Lord Vishnu. When every attempt to stop him fails, his sister, Holika believed to be immune (免疫的) to fire, joins in the effort by inviting the young boy to sit with her inside a huge fire. Helped by the power of Lord Vishnu, Prahlada escapes safely, while the evil Holika is burned to death. To remember this event, huge outdoor fires are lit in the night before Holi in order to clean the air of evil spirits and to celebrate the death of the evil.

    So what's so great about this day? While there are some fun parades (游行) and folk songs and dance performances, the most fun of all is walking to the streets and splashing (泼洒) people with water guns and dry colors and even covering them with entire buckets of colored water. On this day, everybody is fair game, no matter how old or how young.

    At about midday, the splashing comes to an end and people living close to oceans or rivers usually take a bath in the water to clean themselves before going home to a delicious home­made big dinner and a well­deserved short sleep, following this full day of fun and activities.

    Cultural rules determine every aspect of food consumption. Who eats together defines social units. For example, in some societies, the nuclear family is the unit that regularly eats together. The anthropologist Mary Douglas has pointed out that, for the English, the kind of meal and the kind of food that is served relate to the kinds of social links between people who are eating together. She distinguishes between regular meals, Sunday meals when relatives may come, and cocktail parties for relatives and friends. The food served symbolizes the occasion and reflects who is present. For example, only snacks are served at a cocktail party. It would be inappropriate to serve a steak or hamburgers. The distinctions among cocktails, regular meals, and special dinners mark the social boundaries between those guests who are invited for drinks, those who are invited to dinner, and those who come to a family meal. In this example, the type of food symbolizes the category of guest and with whom it is eaten.

    In some New Guinea societies, the nuclear family is not the unit that eats together. The men take their meals in a men's house, separately from their wives and children. Women prepare and eat their food in their own houses and take the husband's portion to the men's house. The women eat with their children in their own houses. This pattern is also widespread among Near Eastern societies.

    Eating is a metaphor that is sometimes used to signify marriage. In many New Guinea societies, like that of the Lesu on the island of New Ireland in the Pacific and that of the Trobriand Islanders, marriage is symbolized by the couple's eating together for the first time. Eating symbolizes their new status as a married couple. In U.S. society, it is just the reverse. A couple may go out to dinner on a first date.

    Other cultural rules have to do with taboos against eating certain things. In some societies, members of a family group, are not allowed to eat the animal or bird that is their totemic ancestor. Since they believe themselves to be descended from that ancestor, it would be like eating that ancestor or eating themselves.

    There is also an association between food prohibitions and rank, which is found in its most extreme form in the caste system of India. A caste system consists of ranked groups, each with a different economic specialization. In India, there is an association between caste and the idea of pollution. Members of highly ranked groups can be polluted by coming into contact with the bodily secretions, particularly saliva(唾液),of individuals of lower-ranked castes. Because of the fear of pollution, Brahmans and other high-ranked individuals will not share food with, not eat from the same plate as, not even accept food from an individual or from a low-ranking class.

    Can you understand this sentence? If you can't, don't feel too bad: neither could the middle school teacher in England who received this as homework. This is Netspeak: the language of computerized communication found on the Internet or cellphones. To newcomers, it can look like a completely foreign language.

    School teachers and parents say this new form of writing is harming (破坏) the English language. Increasing spelling and grammatical mistakes can be seen in students' writing. They fear the language could become corrupted (面目全非的).

    Everyone should just relax, say linguists (语言学家). They believe Netspeak is in fact more of a good thing. David Crystal, from the University of Wales, argues that Netspeak and Internet create a new language use and the almost lost art of diary writing has been picked up again. Geoffrey Nurnberg, from Stanford University, agrees. “People get better at writing by writing,” he says. “Kids who are now doing text messaging, e-mail, and instant messages will write at least as well as, and possibly better than, their parents.”

    Linguist James Milroy says, for centuries, it is believed without exception that young people are harming the language. And when today's teenagers become tomorrow's parents, they too will think this way. Milroy argues that languages do not and cannot become “corrupted”; they simply change to meet the new needs.

    However, Netspeakers do agree that it is important to teach young people how to speak and write Standard English. Cynthia McVey says, “I can understand Netspeak worries teachers and it's important that they tell their pupils that text messaging is for fun, but that learning to write proper English is a must for their future.”

    Pablo Picasso was an amazing painter who experimented with colour and shape. Picasso wanted to find ways to paint emotions. His paintings opened people's minds and showed there were many ways to express ideas.

    Born in Spain in 1881, Picasso learned to paint at an early age because his father was a painter. At fourteen, Picasso began attending the Academy of Fine Arts in Barcelnoa. Although Picasso did well, his teacher wouldn't let him develop his own style. So he change schools. Though his new teachers praised his work, they still criticized it as being too different. Picasso made up his mind to express himself in his own way.

    Disappointed with his career in Spain, nineteen-year-old Picasso moved to Pairs, where he learned about abstract art. He started copying famous paintings so he could paint in any style. However, an important development in his own style came along when his best friend committed suicide（自杀）. Picasso was so upset that he painted only in blue and gray. He painted the poor and the disabled. This is known as his "Blue Period".

    In 1904, his painting style changed again when he fall in love with an artist's model. He began painting everything with colors of rose, red and pink. He mainly painted artists during this time, called his "Rose Period."

    Picasso's style went through style change as he began to learn African art and geometry（几何学）. Instead of painting with different colors, he used different shapes. His paintings made people surprise because they looked like they had been broken and put back together incorrectly. Everything was geometric and abstract. Picasso's new style became known as "Cubism." Cubism was so unique it became very popular.

Pablo Picasso in most remembered for his Blue, Rose, and Cubist periods. But Picasso never stopped experimenting with painting. His painting styles kept changing until his death at the age of ninety-two.

Video calls are a common occurrence, but have you imagined being able to touch the person on the other end of the line? Scientists are making this a reality.

Researchers at the University of New South Wales, Australia, have invented a soft skin stretch device (SSD), a haptic device that can recreate the sense of touch. Haptic technology can mimic the experience of touch by stimulating localized areas of the skin in ways that are similar to what is felt in the real world, through force, vibration or motion.

Vibration is the most common haptic technology today and has been built into many electronic devices, such as one attached to the back of a trackpad in laptops. However, haptic feedback with vibration becomes less sensitive when used continuously. The existing technology also has great difficulty recreating the sense of touch with objects in virtual environments or located remotely.

The new technology overcomes issues with existing haptic devices. The research team introduced a novel method to recreate the sense of touch through soft, artificial "muscles".

It works like this: imagine you call a friend in Australia. You wear a haptic glove with the SSDs and your friend also wears a glove with 3D force sensors. If your friend picks up an object, it will physically press against your friend's fingers. And the glove with 3D force sensors will measure these interactions. The force signals can be sent to your glove so your device will generate the same 3D forces, making you experience the same sense of touch as your friend.

The haptic devices could be used in various fields, allowing users to feel objects inside a virtual world or at a distance. This could be especially beneficial during such times like the COVID-19 pandemic when people rely on video calls to stay connected with loved ones. Or it could be used in medical practices. Doctors can feel a patient's organ tissues without touching them.
