Last week, we talked about the conflict(冲突) between sleepy teenagers and early morning classes. Many people commented(评论) on our website.

For example, Damla Ece in Turkey wrote: I agree with the idea of starting lessons later so teenagers can feel better in the morning. But sleeping more than seven hours can be wasting time for students.

    Tran in Vietnam disagreed: I think teenagers, on average, need eight to ten hours of sleep every day. It's useless to try to force them to concentrate while they can't concentrate.

    Afshin Heydari from Iran wrote: schools should start early to avoid heavy traffic later in the morning.

    And Suze from Jordan wrote: When I was a teenager, I enjoyed taking my courses as early as possible. That way I could find a long time in the day to do my own activities.

    But Azra from Kyrgyzstan said: the reason why schools start early here is a lack of classrooms.

    And Joruji in Japan wrote: When I was a teenager, I used to get up before six to go to school, which was far from home, and I don't remember having problems. I think nowadays the Internet, TV games and cell phones make teens go to sleep later.

    Thirty-year-old Kika in Spain said: In my opinion, young people are very lazy.

    But Dennis Jin disagreed: For high school students in China, we must reach the classroom at 6:20 in the morning and be back home usually at 10:00 in the evening. Then we'll have some extra schoolwork to do. Can you imagine how long we could sleep every day?

    Teenagers are not the only ones who suffer. Kathy in Canada wrote: My daughter likes complaining about everything in the morning, and I know that this is from lack of sleep. I wish schools should change their start time to 8:30 or 9:00 in the morning.

    And Naima Star in Libya wrote: Getting up so early in the morning and leaving the warm bed is so difficult, especially in the cold weather. It reminds me of that old song: "It's nice to get up in the morning, but it's nicer to stay in bed."

    John Blanchard stood up from the bench, straightened his Army uniform, and studied the crowd of people making their way through Grand Central Station. He looked for the girl whose heart he knew, but whose face he didn't, the girl with the rose.

    His interest in her had begun thirteen months before in a Florida library. Taking a book off the shelf he found himself intrigued, not with the words of the book, but with the notes penciled in the margin. The soft handwriting reflected a thoughtful soul and insightful mind. In the front of the book, he discovered the previous owner's name, Miss Hollis Maynell. With time and effort he located her address. She lived in New York City. He wrote her a letter introducing himself and inviting her to correspond. The next day he was shipped overseas for service in World War II.

    During the next year and one month the two grew to know each other through the mail. Each letter was a seed falling on a fertile heart. A romance was starting Blanchard requested a photograph, but she refused. She felt that if he really cared, it wouldn't matter what she looked like.

    When the day finally came for him to return from Europe, they scheduled their first meeting —7:00 PM at the Grand Central Station in New York. “You'll recognize me,” she wrote, “by the red rose I'll be wearing on my lapel.” So at 7:00 he was in the station looking for a girl whose heart he loved, but whose face he'd never seen.

    I'll let Mr. Blanchard tell you what happened: A young woman was coming toward me, her figure long and slim. Her blonde hair lay back in curls from her delicate ears; her eyes were blue as flowers. Her lips and chin had a gentle firmness, and in her pale green suit she was like springtime come alive. I stared at her, entirely forgetting to notice that she was not wearing a rose. As I moved, a small, attractive smile curved her lips. “Going my way sailor?” she murmured.

    Almost uncontrollably I made one step closer to her, and then I saw Hollis Maynell. She was standing almost directly behind the girl. A woman well past 40, she had graying hair tucked under a worn hat. She was more than plump, her thick-ankled feet thrust into low-heeled shoes. The girl in the green suit was walking quickly away. I felt as though I was split in two, so keen was my desire to follow her, and yet so deep was my longing for the woman whose spirit had truly companioned me and upheld my own.

    And there she stood. Her pale, plump face was gentle and sensible, her gray eyes had a warm and kindly twinkle. I did not hesitate. My fingers gripped the small worn blue leather copy of the book that was to identify(识别)me to her.

    This would not be love, but it would be something precious, something perhaps even better than love, a friendship for which I had been and must ever be grateful. I squared my shoulders and saluted and held out the book to the woman, even though while I spoke I felt choked（哽咽）by the bitterness （痛苦）of my disappointment. "I'm Lieutenant （中尉）John Blanchard, and you must be Miss Maynell. I am so glad you could meet me; may I take you to dinner?"

    The woman's face broadened into a tolerant smile. "I don't know what this is about, son," she answered, "but the young lady in the green suit who just went by, she begged me to wear this rose on my coat. And she said if you were to ask me out to dinner, I should go and tell you that she is waiting for you in the big restaurant across the street. She said it was some kind of test!"

    It's not difficult to understand and admire Miss Maynell's wisdom. The true nature of a heart is seen in its response to the unattractive. "Tell me whom you love," Houssaye wrote, "And I will tell you who you are."

    BEIJING, China —Pollution in China remains very serious as the country's rapid economic growth brings new environmental problems, a minister said Saturday.

    Vice Environment Minister Zhang Lijun said China has made progress on environmental protection, but admitted that its rapid economic growth over the past decade has had a negative effect on the environment.

    "Our rapid economic development has continuously brought our country new environmental problems, particularly dangerous chemicals, electronic waste and so on. These environmental pollutants (污染物) bring new problems and affect human health," Zhang told a news conference.

    He said that emissions(排放)of traditional pollutants remain high and some areas have failed to meet government standards.

China has pledged to continue reducing emissions this year of three key air pollutants— ammonia nitrogen, sulfur dioxide and nitrogen oxide. The government has also promised to bring down demand for chemical oxygen—a measure of water pollution by l.5 percent from the 2010 levels.

    In the last five years, there were 912 "environmental emergencies" involving heavy metal pollution, including several well-publicized instances of mass contamination, Zhang said. Thousands of children were affected by lead poisoning in several provinces in 2009 and 2010 because they lived near metal smelters or battery factories.

    The minister noted that rapid development in the next five years would increase the need for China to improve environmental protection and shift to a more sustainable(可持续的) model of economic development from its dependence on industries which consume huge quantities of energy.

    China is focusing on clean energy, including solar, wind and nuclear power, as one way to reduce its dependence on coal, which generates three-quarters of its electricity and is also used for winter heating in northern cities. China also hopes the strategy will reduce its demand for oil and gas and increase economic growth and jobs.

    Zhang told reporters there was no plan to adjust China's overall strategy for nuclear development but he said Beijing will learn lessons from Japan after a violent earthquake resulted in a radioactive leak(放射能泄露).

    "Some lessons we learn from Japan will be considered in the making of China's nuclear power plans," he said. "But China will not change its determination and plan for developing nuclear power."

    China is fondly remembering one of its most famous radio voices, a man whose vivid storytelling was a comfort to millions of people, from commuters stuck in traffic to restless teens struggling to sleep. Shan Tianfang, was a leading performer of the traditional Chinese art form pingshu, which translates as "storytelling".

    Pingshu dates from the Song Dynasty (AD960-1279) when performers would entertain villagers by telling stories in a particularly emotive style. It remains particularly popular in north-eastern China. Performers wear traditional dress and use very basic props - often a folded fan and a gavel. Pingshu is sometimes performed in tea houses and small theatres, but many Chinese associate the art form with radio. And in a country where sleeping problems are commonplace, pingshu is still popular as a way of helping people to wind down at bedtime.

    Shan Tianfang was born in 1934 in Yingkou, in north-eastern Liaoning province. His family introduced him to folk arts from a young age and he began learning pingshu when he was 19. He became known in Liaoning for his work on stage and in local teahouses during the 1950s and 1960s, and performed in an art troupe around the region. From 1966-1976, Shan, along with other pingshu performers like Yuan Kuocheng, was forced to stop work. During the 1980s.Shan made the transition (转型) to state-run radio, and his captivating storytelling became comfort listening for people across the country. By the 1990s, Shan had become a well-known face on state TV, even performing in the annual Spring Festival Gala show. He has died aged 84 following a long illness.

    Shan performed over 12,000 stories on TV and radio. His stories attracted people of all ages. One of his most acclaimed performances is of the Heroes in the Sui and Tang Dynasties. He gave countless performances of the “Four Classic Novels” (Romance of the Three Kingdoms, Journey to the West, Dream of the Red Chamber and Water Margin) and also helped to bring lesser-known classical Chinese literature to new audiences.

    He was able to use the medium to entrance his audience and in the process he helped to popularise classical Chinese literature. As film director Zhang Jizhong told the Global Times newspaper: “He could describe a scene and a character extremely vividly. He once had a long talk with me about adapting the heroic stories he told into films or television shows to help promote Chinese classics and traditional culture.”

    But in his later years, the growth of online and digital media exposed the challenges of keeping his art form alive. Shan turned his efforts towards writing books and opening performance schools to teach pingshu to young people. They included the Shan Tianfang Culture and Media Academy in Beijing, a Shan Tianfang teahouse and “storytelling base” in Anshan in Liaoning province. Meanwhile, modern productions of pingshu reference (引用，参照) contemporary  (现代的) culture to draw in new performers and audiences. Performers like Guo Heming have emerged, putting a modern spin on pingshu by adapting popular works, including the Harry Potter stories.

    Although he wasn't particularly active on social media, he amassed more than one million fans on the Sina Weibo platform.

A memorial was held for him on 15 September but millions of Chinese will miss his voice.

    Are people less happy or more happy the older they get? A study found that people generally become happier and experience less worry after age 50. In fact, it found that by the age of 85, people are happier with their life than they were at 18.

    The finding came from a Gallup survey of more than 340,000 adults between the age of 18 and 85 in the United States.

    Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of 22 and 25. Stress levels dropped sharply after people reached their fifties.

    Happiness was highest among the youngest adults and those in their early seventies. But the people least likely to report feeling negative emotions were those in their seventies and eighties. The survey also found that men and women had similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men did.

    The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.

    So why would happiness increase with age? One theory is that, as people get older, they become more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.

    The original goal of the study was to confirm the popular belief that aging is connected with increased sleep problems. The survey did find an increase during middle age, especially in women. But except for that, people reported that they felt their sleep quality improved as they got older.
