Britons may like to complain a lot, but they rarely do so right now, explains BBC writer Ruth Margolis. They would rather grumble (发牢骚) afterward. This is because Britons hate to put someone out and cause any embarrassment. Margolis writes, “For instance, I'm much more comfortable just leaving that piece of raw chicken on my plate instead of complaining to restaurant staff. But beware: if this kind of thing happens when you're dining with an American, they will most likely speak up on your behalf and not understand why you find this ashamed.”

    In a BBC blog post comparing cultural differences between the UK and the US, Margolis mentions a few other things that Americans like to do that are offensive to Britons.

● Not making introductions

    Margolis says most Britons dislike this approach because “talking to strangers without being introduced gives them a stomachache”. Americans rarely introduce a new friend to their friends at parties. Strangers are supposed to introduce themselves.

● “Quite” good

    Using “quite” to mean “very” happens a lot in the US. But if you are invited to a dinner party in Britain, don't describe the meal as “quite good” if you want to express high praise. To Britons' ears, “quite” detracts from the “good”: the meal was OK but could have been better.

● Money Talk

    Americans can talk about money subjects for hours without feeling uncomfortable. For Britons, says Margolis, “Talking about how much we make is unthinkable — even 1ess so than discussing our feelings.”

● Over-politeness

    “It's not that I want shop assistants to be actively rude. But neither do I want to expend energy responding to someone who's been paid to ask: ‘How are you today?'” says Margolis. In the US, it is not unusual to be greeted by a perfect stranger as “honey” or “sweetie”. But Margolis says Britons find put-on friendliness, especially in stores, deeply irritating.

    When another old cave is discovered in the south of France, it is not usually news. Rather, it is an ordinary event. Such discoveries are so frequent these days that hardly anybody pays heed to them. However, when the Lascaux cave complex was discovered in 1940, the world was amazed. Painted directly on its walls were hundreds of scenes showing how people lived thousands of years ago. The scenes show people hunting animals, such as bison or wild cats. Other images depict birds and, most noticeably, horses, which appear in more than 300 wall images, by far outnumbering all other animals.

    Early artists drawing these animals achieved a monumental and difficult task. They did not limit themselves to the easily accessible walls but carried their painting materials to spaces that required climbing steep walls or going on hands and knees into narrow passages in the Lascaux complex.

    Unfortunately, the paintings have been exposed to the destructive action of water and temperature changes, which easily wear the images away. Because the Lascaux caves have many entrances, air movement has also damaged the images inside.

    Although they are not out in the open air, where natural light would have destroyed them long ago, many of the images have deteriorated and are hardly recognizable. To prevent further damage, the site was closed to tourists in 1963, 23 years after it was discovered.

    How many men do housework? Recently a European commission (委员会) tried to find out people's ideas and reactions to the women's movement. As part of their survey (调查), they asked many men and women the question: “Who does the housework?” The men answered very differently from the women!

    The housework they asked people about were: preparing meals, washing dishes, cleaning the house and babysitting. 48% of British husbands said they did these things. 37% of Danish men helped in the house. But only 15% of Italian men said they did the housework; many of them said they never helped at all.

    But there was an interesting point of view from the wives. According to British wives, only 35% of their husbands helped in the house. And Italian wives said that their husbands hardly ever helped. The Italian and British men did not tell the truth! The Commission found that Danish men were the most trustful husbands; their answers were the same as their wives' answers.

    Do the men you know help in the house? Do you think the survey gives a true picture in your experience?

    If someone asked you to quantify (衡量) the time you spend online, how would you answer? If you're like one-fifth of Americans, you'd likely say “almost constantly.” New research shows that 21 percent of Americans report that they're online more or less constantly.

    Andrew Perrin, a research assistant at Pew, did a survey about Internet use. During the survey, adults were asked how much they go online. 13 percent said they don't go online and 13 percent said they go online several times a week or less. Only 10 percent said they go online once a day and much larger quantities said they go online several times a day (42 percent) or “almost constantly” (21 percent).

    Interestingly, there wasn't a gender split (性别分化) when it came to near constant Internet use. Age seems to be the great divider: Only six percent of people over 65 said they were online that much. Those who reported that they were online all the time included 12 percent of 50- to 64-year-olds, 28 percent of 30- to 49-year-olds and 36 percent of 18- to 29-year-olds.

    Don't suppose that teenagers are online more than adults, however. In another survey, Pew found that while they did have a slight edge on adults in general when it came to “almost constant” Internet use, 24 percent said they were online pretty much all the time. They still fell greatly behind the 36 percent of adults between 18 and 29 years of age who were always online.

    Given that the United Nations considers unrestricted (无限制的) Internet access (接入) to be a human right, the number of Americans who report being online “almost constantly” could rise along with availability and affordability. But it remains to be seen whether being online all the time is actually something to long for, or how constant connectivity will affect American culture in the long term.

    NASA's (美国宇航局的) newly announced space tourism program is possibly the biggest mistake in the agency's history.

    Beginning as early as 2020, NASA will offer visits to the International Space Station for $35,000 per night, not including transportation, to pretty much anyone who can pass a physical.

    The reason this is a mistake, and a big one, is that NASA has worked for generations to create an image of astronauts as extraordinarily skilled, highly trained, courageous heroes. For example, NASA invites grade schools to participate in creating experiments that are carried on the space station. The astronauts talk to kids from space, sending a message that if you study, work hard and learn math and science, you may reach these heights, too.

    According to one report, Las Vegas-based Bigelow Aerospace is making plans to haul four tourists at a time to the space station on SpaceX rockets. U.S. taxpayers forked over a hundred billion dollars to build the International Space Station. It would be nice to try to preserve the image of it as an inspirational achievement, instead of turning it into a flying Howard Johnson's.

    NASA's press release about the space tourism program tries to cast it as a partnership with the private sector to "provide expanded opportunities" at the space station to "manufacture, market and promote commercial products and services." But it also states that one goal is "quantifying NASA's long-term demand for activities in low-Earth orbit."

    The space station has been costing U.S. taxpayers between $1.5 billion and $3 billion each year. If it's perceived as a private Disneyland for the top tax bracket, public support for the entire space program could be at risk.

    But worse, we will have degraded what once inspired us. Sometimes a nation needs stars in its eyes.

    Garbage sorting has become a hot issue around China, especially after Shanghai began carrying out a regulation on July 1.

    Beijing, as a forerunner in environmental protection, has thus been expected to follow suit. The capital of the country has long been campaigning for sorting and recycling household waste, as part of its environmental drive for sustainable growth, local media reported.

    The current regulation gives garbage sorting responsibilities to government departments, property management groups and other organizations. It also gives rules for companies, outlining how they're responsible for waste collection, transportation and treatment. Only individuals are not subject to responsibilities.

    The long-awaited revision will soon change the situation, "Taking out the trash without sorting it properly will be illegal," said Sun Xinjun, director of the Beijing Commission of Urban Management. In Shanghai, violators are now fined up to 200 yuan ($30)for trash-sorting violations. The maximum fine in Beijing will not be less than that, he said.

    The Beijing city government first set out to promote garbage sorting in 2009. Authorities have since called on citizens to sort their household waste into four types-recyclable waste, kitchen trash, dangerous waste and others-and leave it in a corresponding dustbin or trash can. Blue-colored dustbins signify items within are recyclable, green represents kitchen trash, red corresponds to dangerous materials and grey to other waste.

    To promote the awareness of garbage sorting and expand the base of participants, authorities have employed workers to help residents on the spot. With intelligent devices, those who throw in recyclable waste at given sites will be rewarded with bonus points, which can be used to buy daily goods. At some communities, there are no color-coded dustbins. Instead, a scheduled garbage collection service is offered to help improve the environment. In other communities, workers offer a door-to-door service to collect recyclables or kitchen waste.

    Beijing Environmental Sanitation Engineering Group has been promoting new garbage sorting facilities such as recycling cabinets and smart kitchen waste trash cans since 2016, Xinhua News Agency reported. Nearly 26,000 metric tons of household waste is generated across Beijing on a daily basis and 29 terminal garbage disposal facilities are working at full capacity. Nearly 9.3 million tons of household waste was processed in the city last year.
