As a Fulbright（富布莱特法案基金）scholar at Yale, I wanted very much to get some individual help from some famous professors, but their office-hours were only once a week and there were always students waiting outside. At first, I was too polite to get their help. Then I realized that Chinese politeness does not work in this society. I needed to be aggressive to get what I wanted. I also noticed that Chinese students or Asian students were very polite in class while American students often interrupted the professor, asking questions and dominating the discussion. The Chinese students were not as aggressive as American students.

    I was impressed by the role of the professor in the class. The professor didn't act as an authority, giving final conclusions, but as a researcher looking for answers to questions together with the students. One linguistic feature of his interacting with his students was that he used many modal verbs-far more than I did in Beiwai. When answering questions, he usually said: “this is my personal opinion and it could be wrong. It would be a good idea if you could read the book I mentioned the other day.” Or,“ You may find the book I recommended helpful.” Or,“You could be right, but you might find this point of view also interesting.” When making comments on students' performances, the professor usually said:” It might have been much clearer if you had taken in some of the ideas we discussed earlier this semester.”

    In China, authorities are always supposed to give wise decisions and correct directions. Therefore students always expect the professor to give an answer to the question. I still remember how annoyed they were when foreign teachers did not provide such an answer. Their expectations from authorities are much higher than those of American students. Once the Chinese students got the answer, they were sure about it. That is why they make far more certain statement than American students. That is why Chinese students find it difficult to use modal verbs because the function of modal verbs is to provide room for negotiation and different ideas.

    Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat.

    Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more.US researchers say that social excitement aids weight loss by turning white fat into brown fat. White fat stores calories and makes us fatter, while brown fat burns energy to produce heat. Turning white fat into brown fat is extremely difficult, normally requiring long-term stay in cold conditions or exciting part of the body's nervous system.

    However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown fat. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and they lost far more weight over the course of the study than their “couch potato” fellows.

    Study's author, Dr Mattew During whose team's findings appear in the journal Cell Metabolism, said,“I'm still amazed at the degree of fat loss that occurs.” Explaining how new technology had threatened face-to-face socializing, he added,“It's not just a sedentary (久坐的)lifestyle and high calorie foods, but an increasing lack of social activities.” Co-author Dr Lei Cao said,“Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.”

    It is made from grapes grown without pesticides (杀虫剂) and chemicals, is kind to the environment and rarely causes hangovers (宿醉). Sales of organic(有机的) wine are booming in the UK.

    According to the organic food and farming group Soil Association, sales of organic beers, wines and spirits rose by 14.3% last year to reach nearly ￡6 million, driven by the demand from consumers who are increasingly seeking “natural” food.

    “It seems that people are rediscovering their link with the environment through organic food. Organic wines also taste better, perhaps due to less use of man-made chemicals.” said Finn Cottle of Soil Association. As well as the benefits of producing grapes without using pesticides, organic wine also contains less sulphur dioxide (二氧化硫), which can contribute towards hangovers.

    Supermarkets are increasing supplies on their shelves to meet consumer demand, while the switch to online shopping has also helped, as people are more easily able to find what they are looking for. Vintage Roots is now one of the UK's biggest online shops of organic wine, while Ocado provides more than 100 different organic wines and Daylesford, best-known for its organic vegetable boxes, has branched out into organic wine and spirits.

    The discount supermarket Aldi is set to start its first collection of so-called “green” wines this week, offering eight wines with organic certificates. Aldi expects the wines to appeal to the young shoppers who are increasingly concerned about the environmental influence of the produce that they are buying and consuming.

    English organic wine producer Oxney Estate's Noir Rosé recently won the Waitrose prize for the most outstanding rosé wine at the competition. A spokeswoman for Waitrose said:“Organic wine is a growing trend globally and we have seen sales increase by 16% in the last year”.

    In a world full of Kates and Sarahs, you might think it'd be nice to have a unique name to help me stand out in a crowd. Being named Stacia (pronounced stay-sha) is not so lucky to me. I'll get the occasional "Your name is so pretty" after introducing myself, but eventually my name causes me more frustration than happiness. For example, Microsoft Word always tries to tell me my name isn't a real word. I couldn't even pronounce my own name correctly until I was five.

    I once had a professor who pronounced my name differently each class. After a while I stopped correcting him, and that's been my reaction to strangers ever since. In other cases, I'd rather tell the seller my name is Staci and save both of us, as well as the people standing behind me in line, valuable time.

    Meeting new people gives me anxiety, and I've realized it's easier just to lie about my name altogether in certain cases. Actually I did—so many times that Brittany is now my chosen "going out" name. It may have caused some confusion for my friends at first, who would let out a small laugh or have a confused look, but I've trained them to keep a straight face whenever I whip out this fake (假的) name. Now going out on weekends means I get to have a shift of identity.

    Frustrations aside, being the owner of a unique name has made me appreciate the little things in life. Someone pronouncing or spelling my name correctly on the first try brings me more joy than it probably should. I also love it when I meet another Stacia and we get to bond over our shared struggles.

    To any other Stacias reading this—I feel you, girl. P. S. I apologize to any real Brittanys out there. Thanks for letting me borrow your name.

    A hospital has been forced to ban Pokemon Go players from the site after a monster hub(妖怪枢纽站) was found in the A&E department. Royal Stoke University Hospital discovered that its casualty unit(急诊室) is on the same spot as a Pokemon Go 'gym' —— where players can train their newly caught Nintendo creatures.

    The University Hospitals of North Midlands Trust agreed last week that patients can play Pokemon Go on wards because walking around is healthy. But the Trust has been forced to post a warning on its website about public access to A&E. It said if Pokemon Go becomes a major annoyance it would ask Nintendo—— which decides on the locations of the virtual gyms according to GPS——to have it removed from the premises(道馆).

    Kevin Parker, associate chief nurse, said, "Members of the public who do not need to be at Royal Stoke should not attempt to enter A&E or any other part of the hospital building to play the game. The A&E department is incredibly busy this summer. We want the public to understand that anybody who visits the hospital solely to play the game will provide an unwanted distraction to the important work of the hospital. I'm also aware of various reports in the media of unsafe areas that the game has been played in."

    “Royal Stoke University Hospital is a safe area where gamers can enjoy Pokemon Go." Michelle Harris, the Trust's manager, said the game could still be played by those already in hospital. "We recognize that the Pokemon Go game encourages walking and exercise, which is something that the Trust is equally keen to promote," she said.

    There are a number of "walking routes" established throughout the Trust that can be used to combine walking and playing the game. "Walking just 30 minutes, five times a week, can help reduce the risk of preventable illnesses such as obesity, diabetes, and heart disease."

    There have been several warnings about the game since its UK release. Last week a group of teenagers in Wiltshire were left stranded almost 100ft underground after they got carried away searching for Pokemon Go characters. The four boys, aged 16 and 17, ended up getting lost and had to wait to get a phone signal before they could call for help. Eventually, they contacted Dorset and Wiltshire Fire and Rescue team, who took them to safety. Damien Bence, of the fire and rescue team, said: "Pokemon Go is obviously leading people into dangerous situations."
