Manners nowadays in big cities like London are particularly non-existent. It's nothing for a big, strong schoolboy to push an elderly woman aside in the dash for the last remaining seat on a bus, much less stand up and offer his seat to her, as he ought to. In fact, it is saddening to note that if a man does offer his seat to an older woman, it is nearly always one from the older generation.

    This question of giving up seats in public transport is much argued by young men, who say that, since women have claimed equality, they no longer deserve to be treated with courtesy and that those who go out to work should take their turn in the rat race like anyone else. Women have never claimed to be physically as strong as men. Even if it's not agreed, however, that young men should stand up for older women, the fact remains that courtesy should be shown to the old, the sick and the burdened. Are we really so lost to all ideals of unselfishness that we can sit there indifferently reading the paper or a book, saying to ourselves "First come, first served", while a gray-haired woman, a mother with a young child or a cripple stands? Yet this is too often seen.

    Older people, tired and easy annoyed from a day's work, aren't angels, either-far from it. Many an argument or an insulting quarrel breaks out as they feel tired of pushes in the queue and shove(猛推) each other to get on buses.

    If cities are to remain pleasant places to live in at all, however, it seems necessary, not only that communication in transport should be improved, but also that communication between human beings should be kept smooth and polite. Shop assistant won't bother to assist, taxi drivers shout at each other as they dash dangerously round comers, bus conductors pull the bell before their desperate passengers have had time to get on or off the bus, and so on. It seems to us that it's up to the young and strong to do their small part to stop such deterioration(恶化).

    A qualified doctor who rarely practiced but instead devoted his life to writing．He once said: “Medicine is my lawful wife, and literature is my lover．” Russian writer Anton Pavlovich Chekhov, was a great playwright and one of the masters of the modern short story．

    When Chekhov entered the Moscow University Medical School in 1879, he started to publish hundreds of comic short stories to support his family．After he graduated, he wrote regularly for a local daily newspaper．

    As a writer he was extremely fast, often producing a short story in an hour or less．Chekhov's medical and science experience can be seen through the indifference (冷漠) many of his characters show to tragic events．In 1892, he became a full time writer and published some of his most memorable stories．

    Chekhov often wrote about the sufferings of life in small town Russia．Tragic events control his characters who are filled with feelings of hopelessness and despair．

    It is often said that nothing happens in Chekhov's stories and plays．He made up for this with his exciting technique for developing drama within his characters．Chekhov's work combined the calm attitude of a scientist and doctor with the sensitivity(敏感) of an artist．

    Some of Chekhov's works were translated into Chinese as early as the 1940s．One of his famous stories, The Man in a Shell, about a school teacher's extraordinarily orderly life, was selected as a text for Chinese senior students．

    A long time ago people thought that the sun went round the earth. In some countries people even said that the sun was a god(神). They thought the god drove across the sky each day on a golden horse. Now we know the earth goes round the sun. It takes the earth a year to go a circle(圈) round the sun. Today men even know how far it is for the earth to go round the sun. They tell us that the earth travels over a thousand miles a minute on its journey round the sun.

    The sun is really a star. It is much bigger than the earth and it is very hot. Some people have been to the moon but we know that no one can ever go to the sun. It is far too hot for people to live anywhere near it. The sun is three hundred thousand times heavier than the earth and more than million times larger.

    Laughter Yoga(瑜伽) is one form of yoga. Madan Kataria, a doctor in Mumbai, India invented it. He believed that people had forgotten how to really laugh. Through his research he made an interesting discovery. The human mind does not know the difference between forced laughter and real laughter. Forced laughter can also lead to a feeling of happiness.

    And then Kataria had the idea for a group of people who would laugh together. He gathered a few of his friends together. They met in a public park in Mumbai. That small group grew and grew! And this is how people began to do Laughter Yoga. People doing Laughter Yoga usually meet together in a Laughter Club. Kataria's friends formed the first Laughter Club in 1995.

    Today, there're over 5,000 Laughter Clubs in 53 countries. But what exactly do people do in a Laughter Club? People in Laughter Yoga meetings usually do a series of exercises. The exercises include body movement, correct breathing, and of course, laughter! At the beginning of the meeting, people may have to force themselves to laugh. But by the end, everyone is usually laughing in a real way! Each meeting is a little different. But there are common exercises groups may do.

    Experts say that the exercises help blood move around the body faster. They also say that Laughter Yoga helps people deal with the bad things in their lives. They say that a person may go into a Laughter Club meeting feeling sad, angry, or worried. But then, people act happy. After a time, forced laughter becomes real laughter. This is one reason why people may enjoy laughter Yoga so much

    "Acting is the least mysterious of all crafts," Marion Brando once said. But for scientists, working out what is going on in an actor's head has always been something of a puzzle.

    Now, researchers have said actors show different patterns of brain activity depending on whether they are in character or not.

    Dr Steven Brown, from McMaster University in Canada, said, "It looks like when you are acting, you are suppressing (压制) yourself; almost like the character is possessing you."

    Brown and colleagues report how 15 actors, mainly theatre students, were trained to take on a Shakespeare role — either Romeo or Juliet — in a theatre workshop. They were then invited into the laboratory, where their brains were scanned in a series of experiments.

    Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party? And would they tell their parents that they had fallen in love?

    Each actor was asked to respond to different questions, based on two different premises (前提). In one, they were asked for their own perspective, while in the other, they were asked to respond as though they were either Romeo or Juliet.

    The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some third-person knowledge or inferences about their character.

    The team said they also found additional reduction in activity in two regions of the prefrontal cortex (前额皮质) linked to the sense of self, compared with when the actors were responding as themselves.

    However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than "pretending" to be someone — it involves embodying (体现) the text and language.
