The Queen's English is now sounding less upper-class, a scientific study of the Queen's Christmas broadcasts had found. Researchers have studied each of her messages to the Commonwealth countries since 1952 to find out the change in her pronunciation from the noble Upper Received to the Standard Received.

    Jonathan Harrington, a professor at Germany's University of Munich, wanted to discover whether accent  changes recorded over the past half century would take place within one person. “As far as I know, there just is nobody else for whom there is this sort of broadcast records,” he said.

    He said the noble way of pronouncing vowels (元音) had gradually lost ground as the noble upper-class accent over the past years. “Her accent sounds slightly less noble than it did 50 years ago. But these are very, very small and slow changes that we don't notice from year to year.”

    “We may be able to relate it to changes in the social classes,” he told The Daily Telegraph, a British newspaper. “In 1952 she would have been heard saying ‘thet men in the bleck het'. Now it would be ‘that man in the black hat'. Similarly, she would have spoken of ‘citay ' and  ‘dutay' , rather than ‘citee' and ‘dutee' and ‘hame' rather than ‘home'. In the 1950s she would have been ‘lorst', but by the 1970s ‘lost'.”

    The Queen's broadcast is a personal message to the Commonwealth countries. Each Christmas, the 10-minute broadcast is put on TV at 3 pm in Britain as many families are recovering from their traditional turkey lunch.

    The results were published in the Journal of Phonetics.

Uncivilized behavior by passengers unacceptable

    For the first time, airline passengers have been blacklisted for uncivilized behavior. Their names will remain on the blacklist for one or two years, according to an announcement by the China Air Transport Association on Saturday. The blacklisting means they will not be able to travel by air until their names are removed from the list.

    Blacklisting passengers who disobey the rules for traveling by air and so place their own interests before everything else, including safety, has long been overdue (迟到的，延迟的).

    There have been frequent reports of passengers making a scene when their flight was delayed or when they believed that they were not treated as they should be on a flight.

    Yet it is natural for some flights to be delayed because of reasons such as bad weather or mechanical problems that need to be solved. However, some passengers seem to take it for granted that their flight must take off at the time stated on their ticket, and they even assume that the members of the cabin crew are simply there to do their bidding(吩咐).

    They forget that they should behave themselves in the first place and that respect is reciprocal (互相给与的).There is no reason for them to be respected when they do not show enough respect for others.

    Observing rules can never be over-emphasized when it comes to flight safety. No one has the right to disregard the rules for any reason. Of course, airlines should provide quality services to meet the needs of passengers. Yet, even if passengers are not satisfied with the service provided, there is still no reason for them to flout the rules that are designed for the safety of all.

    The blacklisting of these three passengers should serve for others to know they have to toe the line (顺从集体).

    I had just moved to San Antonio, Texas. I worked for the tour bus service taking tourists on a short tour of the city's historic places and would end up at the Alamo.

    I was driving back from my last tour on a cool February day on my way back from the San Femando Catholic church with no one on my bus when I saw a man dressed in rags, thinking this person must be an actor or something walking around. I stopped and asked him, “Need a ride?” Without saying anything he just walked on broad and sat down in seat behind me.

    “Where are you heading?” I asked him. He looked up into the mirror at me and replied. “I've got to get to the fort(要塞)and report to Colonel(上校)Travis that the Mexicans are here!” I laughed to myself thinking that this man was a serious actor.

    “I'm guessing you mean the Alamo?” I said back to him. I looked up and saw he wasn't smiling nor laughing. All throughout the ride he was staring in amazement at all the towering skyscrapers and the buildings along the street.

    “I remember when this town was nothing more than a little trading village!” He finally said to me.

    “So what's your name?” I asked him.

    “Daniel Cloud, yours?”

    “David Zime.” I replied as I turned the corner of the street and laid eyes upon the Alamo.

    I pulled up to the sidewalk and opened the door. Cloud got out of his seat and came up to me.

    “Thanks for the ride.” He said extending his hand. I took his palm and it was freezing cold like he just stepped out of the freezer.

    “Not a problem, Mr. Cloud, and don't worry about the fee. It's on the house.” He nodded his head in gratitude like all us Texans do and walked away.

    It wasn't until then that I noticed that he was soaked(浸；泡)to the bone in dripping water and we had not a single drop of rain in a month or more. I just shook my head and closed the door behind him. When I turned around. Discovered amazingly how fast Cloud had gone away!

    A few days later I was reading a book about the Battle of the Alamo when I discovered the most shocking thing I had ever discovered. The names of the 183 defenders of the Alamo were listed on the roll of honor, including Daniel Cloud, who spotted the Mexicans before they took over the streets of San Antonio in February of 1836, and his post was on top of the San Femando Church where I had picked him up!

    The African elephant, which is the largest land animal remaining on earth, is of great importance to African ecosystem. Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the- forest-and-savanna (大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat.

    It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.

    Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.

    What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.

    Before we came to Canada in 1951, when I was three, my parents and I spent a year at refugee camp (难民营) in Austria. We had escaped from what was then called Czechoslovakia. My parents had already lost their livelihood once to the Nazi. Mummy was freed from the Nazi concentration camp Bergen-Belsen and spent the years after the war trying to find her family, only to discover she was the only survivor. She met my father in a small town outside Prague. They married and had me in 1948. When we arrived in Montreal, everything we owned was contained in an army trunk and a couple of army blankets. Mummy bought an old sewing machine and some inexpensive materials and using patterns in magazines, taught herself to sew. Her hands were always going, making something. She learned English by singing along to the hit song as she worked.

    For me, high school was a lonely time. My mother worried that I'd never come out of my shell so she signed me up for classes at the Montreal Children's Theatre. That's where I found my voice with her strong faith in me, Mummy had opened a door. Although she was an educated woman, I never heard my mother said “This is what I gave up for you.” She was always there for my younger brother and me. When I sat in the kitchen with her, I felt safe. When she made soup or sewed a ballet costume for me, it was all a gift, a labor of love. She wanted to make us happy. For a long time, I had a picture hanging in the kitchen saying “Put your heart into it.” I grew up with that phrase. Mummy taught that lesson by example, and it has become my own work ethic(职业道德).

    Who can think of the race between the tortoise and the rabbit when it comes to the greatest races? Sure, that race only took place in ancient Aesop's mind, but while the great modern races can teach us a lot about commitment, perseverance (毅力) and the virtues of having a rather large engine, "The Tortoise and the Rabbit" may tell us everything about animals and even vehicles on this planet.

    In a study published this week, Adrian Bejan, a professor of mechanical engineering, concludes that no one should be surprised that the tortoise wins over the seemingly speedier rabbit. In fact, after analyzing the reported speeds of land-air-and-water-based animals, Bejan concludes that the world's well-known speedsters are actually among the slowest when their movements are averaged out over the course of a lifetime.

    The study builds on Bejan's previous research showing that an animals speed increases with mass regardless of species. And that principle can also be extended to non-living things, like aircraft.

    After studying data from historical airplane models, Bajan noted the speed of each model increased with its size, too. That doesn't sound right. What about the modern jet fighter? How is that relatively small craft not faster than a clumsy large transport plane?

    Again, Bejan harks back to the tortoise. That transport plane spends lots of time in the air, moving regularly across long distances. The fighter jet, on the other hand, may fly across the sky occasionally, but-like the rabbit-it's often found resting on the ground.

    The slow and steady transport plane wins the marathon of life.

    But like so many good stories, Aesop's tale offers even more than a lesson in perseverance.

    At one point, the rabbit asks the tortoise how he expects to win a race at such a slow pace.

    The tortoise—ever focused—doesn't respond But it's the rabbits own words that provide the moment to reflect on, especially in modem times.

    "There is plenty of time to relax," Until there isn't.
