If you had a strange sound in your ear, what would you do? One man in Wales who thought he had a fly in his ear called 999, the emergency services number in Britain. And so did a woman who was worried about her green potatoes. Could she make chips with them? Were they poisonous? She didn't hesitate about calling the local ambulance service to ask. According to a recent report, more than 31,000 non-urgent calls were made to the Welsh Ambulance Service in the last year.

    Inappropriate calls are a headache for health professionals everywhere. In the US, prank calls to 911 happen on a daily basis. Many callers use apps which hide their identity. But those who try to be funny shouldn't be surprised if the police have the last laugh. One man from Colorado was arrested for making more than 1,200 prank calls, according to a report on the US television station KOAA—TV.

    People who take these calls are trained to stay calm and keep a straight face, no matter how strange the call sounds. “There's no way for us to know whether the call is real, accidental or a prank call,” said a public safety worker interviewed by the American TV channel.

    The Head of Clinical Services at the Welsh Ambulance Service, Richard Lee, has a warning for prank callers. He says:“ When people misuse the service it means our precious time is being taken away from someone who really does need our help.” Indeed, these hotlines are supposed to help the seriously ill or those with a life-threatening injury. You never know, one day, the person who needs assistance could be you or someone in your family.

    Culture can affect not just language and customs, but also how people experience the world on surprisingly basic levels.

    Researchers, with the help of brain scans, have a shocking differences in perception (感知) between Westerners and Asians, what they see when they look at a city street, for example, or even how they perceive a simple line in a square, according to findings published in a leading science journal.

    In Western countries, culture makes people think of themselves as highly independent individuals. When looking at scenes, Westerners tend to focus more on central objects than on their surroundings. East Asian cultures, however, emphasize inter-dependence. When Easterners look at a scene, they tend to focus on the surroundings as well as the object.

    Using an experiment involving two tasks, Dr. Hedden asked subjects to look at a line simply to estimate its length, a task that played to American's strengths. In another, they estimated the line's length relative to the size of a square, an easier task for the Asians.

    The level of brain activity, by tracking blood flow, was then measured by Brain Scanners. The experiment found that although there was no difference in performance, and the tasks were very easy, the levels of activity in the subjects' brain were different. For the Americans, areas linked to attention were more, when they worked on the task they tended to find more difficult — estimating the line's size relative to the square. For the Asians, the attention areas lit up more during the harder task also—estimating the line's length without comparing it to the square. The findings are a reflection of more than ten years of previous experimental research into East-West differences.

    In one study, for instance researchers offered people a choice among five pens; four red and one green. Easterners were more likely to choose a red pen while Westerners were more likely to choose the green one.

    Culture is not affecting how you see the world, but how you choose to understand and internalize(使内化) it.

    But such habits can be changed. Some psychological studies suggest that when an Easterner goes to the West or vice versa, habits of thought and perception also begin to change. Such research gives us clues to how our brain works and is hopeful for us to develop programs to improve our memory, memory techniques and enhance and accelerate our learning skills.

    In Britain, many theatres put on shows for children at Christmas and many theatres have a theatre­in­education team working there. This team, made up of actors and teachers, writes plays for children, usually performing them in schools. They do different plays for different age groups and the children often take part in the play in some way.

    Pantomime is a special kind of Christmas show for children. It is loved by people and also allows the audience (观众) to join in.＂Pantomime＂ was the name of the Roman actor who performed shows without speaking — this is where the English word ＂mime＂ comes from.

    A pantomime is always based on a well­known children's story. But there are always certain types of characters in the show and certain situations and events. For example, a pantomime must always include a hero, known as the ＂principal boy＂ and this principal boy is always played by a pretty girl wearing a short costume (服装). Then there is the comic older woman, known as the ＂dame＂ who is played by a man. There is always a group of men and women who sing and dance and often there is a pantomime horse. The horse is played by two men who form the ＂front＂ and ＂back＂ ends inside a ＂horse＂ costume. It is funny and it usually kicks the dame when she isn't looking.

    Members of the audience have to shout a warning to one of the characters and argue (争论) with the character (usually the dame) when she does not believe them. When she shouts, ＂Oh no, it isn't, ＂ the audience always responds with ＂Oh yes, it is!＂ The audience also learns and sings a simple song and a few children are sometimes invited to help one of the characters during the show.

    To fight for the conservation of forest ecosystem, several ecologists including Daniel Janzen convinced Del Oro, an orange juice producer, to donate part of their forestland to a national park. In return, Del Oro was allowed to throw large amounts of waste in the form of orange peels (皮) on a 3-hectare piece of land within the national park at no cost. Dealing with tons of leftover peels usually involved burning them or paying to have them poured into a landfill, so the proposal was very attractive.

    But a year later, another juice company challenged the deal in court, arguing that their competitor was “polluting a national park”. They ended up winning, and the deal between Del Oro and the national park fell through.

    Then in 2013, while discussing possible research avenues with Timothy Treuer, Daniel Janzen mentioned the orange story. Feeling interested, Treuer decided to stop by that piece of land that had been covered with fruit waste 15 years earlier. What he found shocked him.

    “While I would walk over exposed rock and dead grass in the nearby fields, I'd have to climb through undergrowth and cut paths through walls of vines (藤) in the orange peel site itself.” said Timothy Treuer.

    Treuer and his team spent months picking up samples (样品), analyzing and comparing them. They found great differences between the areas covered with orange peels and those that were not. The area with orange waste had richer soil.

    The effect that the orange peels had on the land is probably not that surprising to people familiar with composting (施肥), but what is really shocking is that a judge actually thought the waste of orange “mined” a national park and stopped it from going forward. Now that Timothy Treuer's study has received worldwide attention, this type of “ruining” is being seriously considered as a way of bringing forests back to life.

    You may think there are no differences between British and American people. After all, they speak the same language, don't they? If you ask a British or an American person, he will probably tell you that there are differences. And the differences are quite great.

    What do British people think American people are like? The British think American people are very strange. They make a lot of noise and they laugh too loudly. They are rich, and they only think about money. But the British do say that American people are kind friendly people. They're happy to help you if you are in trouble.

    What do Americans think of the British? Well, they think the British are cold and very unfriendly. They are not interested in success or in making lots of money. They think British is the best country in the world. They look down on other countries. But Americans say that the British are quite hard workers. They are brave and honest. And in time of trouble they face difficulties happily.

    You can see that these ideas can cause misunderstanding between the British and Americans. But when American and British people become friends, they usually find things are not as bad as they expected.

    A new officer with the Huntington Park Police patrols (巡逻) local parks 24 hours a day seven days a week. He doesn't need rest, coffee breaks, a salary or medical insurance, and that is because it is a Robocop.

    The main function of the Robocop is to scan and film the surroundings. Besides cameras with night vision that report 360 degrees, it also has a distress button which is located here, so if somebody is to need assistance or they want to contact the communication center, they can do it by way of that distress button. There are people that are monitoring on the other end.

    This newest police employee is self-charging. It's easy to program it and make changes to the software if necessary. Its maintenance (维护) costs are roughly 75 thousand dollars a year. It travels the entire park. It is a programmed path, but the police are able to change the path and adapt it.

    The Robocop can record the license plates (车牌) of passing cars and check them against an online database of stolen cars. It can also help locate a lost iPhone because it is able to determine a smartphone's MAC address. The police can see from the robot if something wrong happens and then come and figure it out.

    The Robocop can't replace its human handlers. The whole goal is to give police more time to do things machines can't do. The police have been having some concerns about safety of the parks and want an extra set of eyes that will help patrol a 24/7.Robocop's creators believe this model known as K5 is best used for providing security at public places like hospitals, parking lots, parks and airports. So far, it seems to be working out just fine.
