The hit movie Notting Hill（诺丁山）begins with a famous scene. Hugh Grant bumps into Julia Roberts and spills orange juice all over her. After the collision, Grant repeatedly says, “I'm so sorry. I'm so sorry.”

    His actions in this scene are very British. If Roberts' character were from the Britain, than she would probably apologize repeatedly as well – even if the crash were not her fault. But this doesn't happen in the movie, as Roberts is from the US.

    A report in The Telegraph once said that three quarters of British people apologize when they bump into someone in the street – regardless of whether they are responsible or not. In fact, Britons use “sorry” in many situations. For example, if they mishear someone, they say “Sorry?” The person they are talking to will also apologize by replying, “No, I am sorry!” This can go on for up to five minutes as they compete over who is the most sorry.

    Why are Britons so sorry? Mark Tyrell, a psychology writer in the UK, thinks that their apologetic tendencies are rooted in British class system. “We say sorry because historically the new middle class in Britain had to apologize for not being the working class, but also for really being the upper class.” Another theory is that they apologize to avoid conflicts. For example, if they bump into someone, he might get angry. To avoid this, they instantly say “Sorry!”

    True manners are about being considerate, and today's constant use of apologizing shows that we are perhaps not as thoughtful as we once were. The word “sorry” has lost some of its meaning.

    Do you see my point? Sorry, it might just be a British thing.

    I've been in the taxicab business for thirty-five years, and I know there is a lot about it that is not so good. Taxicab drivers have to be tough fellows to be able to work in New York. You've got to fight the New York traffic eight hours a day these days, so people get the wrong impression that they are bad.

    Actually, taxi drivers are just like other people. Most of them will behave as honest fellows. You read in the papers almost every week that a taxi driver turns in money or jewels that people leave in their cabs. If they weren't honest, you wouldn't be reading those stories in the papers.

    One time in Brooklyn, I found a diamond ring in my cab. I remembered helping a lady with a lot of packages that day, so I went back to where I had dropped her. It took me almost two days to trace her down in order to return her ring to her. I didn't get as much as “thank you”. Still I felt good because I had done what was right. I think I felt better than she did.

    I was born and raised in Ireland and lived there until I was nineteen years old. Then I came to this country where I had a family and bought my own cab. Life hasn't been too easy at times, but my wife takes care of our money and we have a good bit put away for a rainy day.

    When I started driving a cab, Park Avenue was mostly a bunch of coal yards. Hoofer's Brewery was right next to where the Waldorf-Astoria is now. I did pretty well, even in those days. In all my years of driving a taxicab, I have never had any trouble with the public, not even with drunks.

    I believe honesty is one of the greatest gifts. I know they call it a lot of fancy names these days, like integrity（正直）, etc. But it doesn't make any difference what they call it; it's still what makes a man a good citizen. This is my code, and I try to live by.

    If your dog looks pleased to see you—it is probably because it loves the particular way you smell.

    The scent (气味)of a familiar human apparently lingers like perfumein the animal's brain—where it causes an instinctive emotional response, research reveals.

    Our scent acts on a part of the canine (犬科的) brain associated with reward and the strongest reactions are produced by humans that pets know best, say scientists in America.

    Gregory Bern, of Emory University in Atlanta, said, “While we might expect that dogs should be highly tuned to the smell of other dogs, it seems that the 'reward response' is reserved for their humans. When humans smell the perfume of someone they love, they may have an immediate, emotional reaction that's not necessarily cognitive (认识的). So is it in dogs. But since dogs have a more sensitive smell than humans, their responses would likely be even more powerful than the ones we might have. In our experiment, however, the owners of the dog were not physically present. The canine brain responses were being caused by something distant in space and time. It shows that dogs' brains have these mental representations of us that persist when we're not there.”

    The experiment involved 12 dogs of various kinds by brain scans while five different scents were placed in front of them. The scent samples (样本)came from the subject (接受试险者) itself, a dog the subject had never met, a dog living in the subject's household. The familiar human scent samples were taken from someone else from the house other than the handlers during the experiment, so that none of the scent donors were physically present.

    The results showed all five scents gained a similar response in parts of the dogs brains involved in detecting smells. Responses were significantly stronger for the scent of familiar humans, followed by that of familiar dogs. The findings showed dogs reacted strongest to the scent of familiar humans even when they were not there. Pets trained as help or therapy dogs showed greater brain activity than the other dogs in the test.

    Researchers say the findings could improve the way to select animals helping wounded old soldiers or disabled people.

    Your local grocery store is a psychological minefield (布雷区), where even the bananas are ripe with mystery.

    ⒈Southpaws (左撇子) have an invisible advantage

    You've probably seen that stores keep go-to items produce, meats, dairy on the outer edge. But did you notice that most of them are set up to make you run counterclockwise (逆时针)? Ninety percent of us are right-handed, so we buy more when it's counterclockwise. You'll also often find the dairy section in the back-left corner: Because dairy is likely on your list, stores make sure you take the longest route to get there. In fairness, it's also a more convenient place to put a fridge.

    ⒉Everything is in its place

    It's safe to say that nothing you see on a shelf is there by chance. The cookies on sale at the end of a passage are likely the result of smart product placement. More expensive items are usually placed at an adult's eye level, while colorful treats and other products for kids are positioned lower to catch the attention of children.

    ⒊Time goes by so slowly

    Stores rarely have windows or clocks. With no reference to the outside world, customers can easily lose track of how long they've been there so that they can buy more. Grocery stores may use another trick to control your sense of time: small floor tiles (瓷砖).

The Museum of Science and Industry

    The Manchester Museum of Science and Industry will give us a more wonderful interpretation of the museum. The 2.8 hectare museum was rebuilt on the site of a huge Victorian warehouse and the world's oldest passenger train station. The number and type of collections are ranked first, and in the power exhibition hall, steam engines used during the Industrial Revolution can still be seen. The display of the railway here is rich and vivid in content. Understanding the history of the Industrial Revolution, the Manchester Museum of Science and Industry is a good choice.

    Power is the central theme of the museum, whether it is a bicycle or a steam engine, not to mention an old car. The history of mankind, as this museum shows, has been constantly running. All human inventions can't be separated from this idea. Life is also about exercise. All the exhibits in the museum are alive. The workers oil and wipe every day. Finally, steam is imported into the machinery to make them run as usual as they did a hundred years ago. Time is also reversed.

    In the power exhibition hall, the steam engine that had been used during the Industrial Revolution was still roaring, and the influence was not reduced. If you want to understand the Industrial Revolution and the role of Manchester in it, you must come and visit it, and you will find answers from the many wonderful exhibitions here.

    The Manchester Museum of Science and Industry completely reproduced the British Industrial Revolution, and ensured that the machines of its scientific and technological inventions operated daily, so that visitors and school children could experience the Industrial Revolution. Therefore, the museum has become an outstanding model for preserving industrial heritage.

    Manchester was known as Cotton Capital, Northern Capital, Second City, and Warehouse City for the Industrial Revolution. The Manchester Museum of Science and Industry is located in the center of Manchester City. It records the cradle (摇篮) of the Industrial Revolution with historical details. Manchester City's history, textiles, energy, communications, aviation, transportation and other industries have risen and fallen with the development of science and technology.

    Are you afraid of sharks? What about snakes or spiders? Put those fears aside: because in the U.S. you're far more likely to be killed or injured by a deer skipping across the road.

    Deer cause more than 200 humans deaths each year, plus some 29, 000 injuries, all because of 1.2 million collisions between vehicles and deer. Most incidents occur in the eastern U.S., where deer prosper without natural predators like wolves and mountain lions.

    "That's the region in the U.S. where deer-vehicle collisions are such a problem, and where it seems like an effective large carnivore reintroduction could make a really big difference." says wildlife biologist Laura Prugh from University of Washington. She thinks it would help to reintroduce predators like mountain lions, also known as cougars, pumas or panthers, to parts of their historic range from which they've been driven out.

    The researchers say that bringing the predators back to the eastern U.S. would mean 22 percent fewer collisions between cars and deer over three decades. Each year would see five fewer human deaths, 680 fewer injuries and a savings of some 550 million. Sophie L. Gilbert thinks there are great socioeconomic benefits of large predator restoration through reduced wildlife-vehicle collisions and she says, says, "Cougars have shown that they can coexist in short distance with people, with very few conflicts, in a lot of areas out west."

    Still, some folks might be understandably nervous about this kind of plan. After all, reintroducing predators doesn't come without risks to pets and to livestock, and very occasionally to people.

    "Our fear of large predators is so natural and intense that I don't think it's possible to just completely clear it with statistics… What I hope is that knowing that there actually can be some measurable benefits might make people a little more supportive and maybe balance that fear a little bit." says Laura.

    Indeed, the statistics show that cougars would prevent five times as many human deaths from deer-related accidents as they would cause by attacks. But it'll be a tough sell: the press will cover cougar attacks, but a statistically prevented death does not make the news. Nevertheless, "If people in the west can put up with having mountain lions around, I would hope that New Yorkers would be up for the challenge as well."
