Awarding wining film Ballad From Tibet(《天籁梦想》) by Chinese director Zhang Wei is scheduled to premiere in New York City on Saturday, March 10.

    The film, which tells the story of four visually impaired kids from China's Tibet autonomous region embarking on a journey for their dreams, will be presented at the Bronx Library Center on Saturday, at Mid-Manhattan Library on Sunday, at Lehman College and Marlene Meyerson JCC Manhattan on Tuesday, and at the Museum of Modern Art on Wednesday.

    Based on a true story, Ballad from Tibet is about the four 1ibetan kids—Thupten, Sonam, Kelsang and Droma—achieving their dreams against all odds.

    Thupten is a 10-year-old boy partially sighted in one eye and blind in the other. His doctor says that there is a chance he could completely lose his sight, but there is an operation that could offer a 50 percent chance of saving his vision.

    His teacher firmly suggests that he should have the operation right away, but Thupten is afraid and wants to see the world before his life is plunged into total darkness.

    Along with his three friends who also suffer from blindness, Thupten embarks on an exciting adventure. Together they decide to go to Shenzhen in South China's Guangdong province, a city more than 37,000 km away from Tibetan regional capital Lhasa.

    The reason for the children's decision to go to Shenzhen is their love of music. They are all talented and want to sing their hearts out in front of national audience by participating in a Shenzhen-based reality show.

    The foursome's trip is indeed fun, but also turns out to be dangerous as well. Luckily, help is on hand along the way in the form of a wandering family, a shepherd, a motorcycle club, and a TV producer's assistant.

    Ballad From Tibet has won the award for Best Children's Feature at the 13th China International Children's Film Festival in November 2017, and earned nominations at 17 different international children's film festivals in Germany, Canada, Japan, Greece, Australia and India.

    One of the questions surrounding climate change is how it might affect the food supply for a growing global population. A new study suggests that researchers have been overlooking how two key human responses to climate—how much land people choose to farm, and the number of crops they plant—will affect food production in the future. The new study focused on the Brazilian state of Mato Grosso, an emerging（新兴的）global breadbasket（产粮地区）that as of 2013 supplied 10 percent of the world's soybeans. The researchers used variations in temperature and precipitation（降水）across the state over an eight-year period to estimate the sensitivity of the region's agricultural production to climate change. Those historical comparisons can help in making predictions about the sensitivity of agriculture to future climate change.

    The study found that, if the patterns from 2002 to 2008 hold in the future, an increase in average temperature in Mato Grosso of just 1 degree will lead to a 9 to 13 percent reduction in overall production of soy and corn. “This is worrisome given that the temperature in the study region is predicted to rise by 2 degrees by 2050,” said Avery Cohn, who led the study.

    Most studies of this kind look only at the extent to which climate shocks affect crop output. But researchers can miss critical dynamics（动力）that can affect overall output, says Leah VanWey, one of the study's senior authors. “If you look at output alone, you're not looking at all of the information because there are economic and social changes going on as well,” said VanWey.

    If output decreases, farmers may put less land area into production because it's not profitable. Farmers may also vary the number of crops they plant in a growing season. Double cropping is common in Mato Grosso. But if the weather is bad, farmers may change their decision to plant a second crop.

    I'd like to share a little story with you about something that happened when I was four. I remember it clearly. Our loving family dog was nearing the end of his life. My father picked him up and put him in a little bed we had made for him. Our dog, my companion, whom we had cared for, bit my father when he attempted to help him. How could he? Why? I couldn't understand it. I didn't like him anymore.

    I hadn't thought about that story for a long time but something that happened last week brought it back to me. I went to speak with a friend. When I knocked on the door, I met in an instant an angry look and a few harsh(尖刻的)words. When the door was slammed(砰地关上)in my face, I stood there shocked, and in a rush, I was reminded of my dog bit my father 20 years ago or so. What brought that story back was that same feeling of betrayal.

    Both stories taught me something the next day. You see, when I got up in the morning and was told my dog had died, it became clear to me that he must have been in great pain. For him to have bitten a family member, he could not have been himself. Much the same for the other story when I learned that my friend's wife had just left him.

    We are all beings of our environments, our opinions and feelings. And all of those things can cause you to say and do things that can't be understood by those who are not in the same situation with you.

    If you meet someone either behaving out of character or acting in a way that doesn't seem to fit the situation, put out your hand and be patient when you think it is least possible for him to do so. You may turn around a story that has a sad ending simply by your actions.

    About twenty of us had been fortunate enough to receive invitations to a film­studio (影棚) to take part in a crowd­scene. Although our “act” would last only for a short time，we could see quite a number of interesting things.

    We all stood at the far end of the studio as workmen prepared the scene，setting up trees at the edge of a winding path. Very soon, bright lights were turned on and the big movie­camera was wheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in “snow”. Two more fans were turned on，and a “strong wind” blew through the trees. The picture looked so real that it made us feel cold.

    The next scene was a complete contrast (对比). The way it was filmed was quite unusual. Pictures taken on an island in the Pacific were shown on a glass screen (幕). An actor and actress stood in front of the scene so that they looked as if they were at the water's edge on an island. By a simple trick like this, palm trees, sandy beaches, and blue, clear skies had been brought into the studio!

    Since it was our turn next，we were left wondering what scene would be prepared for us. For a full three minutes in our lives we would be experiencing the excitement of being film “stars”！

    One of the first things that Jim discovered while living with the Greens was that there were different television channels(频道)in Britain, the BBC broadcasts on two channels: BBC1 and BBC2. There is a mixture of serious and light programmes on BBC1; there are mainly serious programmes on BBC2. ITV is an independent(独立的)channel which carries advertisements(广告). There are no advertisements on the BBC, so everyone must pay some money to the BBC each year. There are both serious and light programmes on ITV. Because of the different channels, it is not surprising that you often see each member in Mg. Green's house wants to choose his or her own favorite channel. This is the sort of thing you hear:

    "There's sports programme on ITV."

    "What's that, children?"

    "We were wondering if we could watch the sports programme on ITV."

    "But I was wondering whether to watch the other programme on BBC1." And so on. The children like ITV; mother prefers BBC1; father prefers BBC2. Jim hasn't made up his mind.

    Did you know that Albert Einstein could not speak until he was four years old, and did not read until he was seven? His parents and teachers worried about his rnental ability.

    Beethoven's music teacher said about him，"As a composer（作曲家）he is hopeless." What if this young boy believed it?

    When Thomas Edison was a young boy, his teachers said he was so stupid that he could never learn anything. He once said, I remember I used to never be able to get along at school. I was always at the foot of my class…My father thought I was stupid, and I almost decided that l was a stupid person. "What if young Thomas believed what may said about him?

    When the sculptor(雕刻家)Auguste Rodin was young; he had difficulty learning to read and write. Today, we may say he had a learning disability. His father said of him, "I have an idiot(白痴) for a son." His uncle agreed. "He's uneducable," he said. What if Rodin had doubted his ability?

    Walt Disney was once fired by a newspaper editor because he was thought to have no "good ideas". Enrico Caruso was told by one music teacher, "you can't sing. You have no voice at all." And an editor told Louisa May Alcott that she was unable to write anything that would have popular appeal.

    What if these people had listened and become discouraged? Where would our world be without the music of Beethoven, the art of Rodin or the ideas of Albert Einstein and Walt Disney? As Oscar Levant once said, "It's not what you are but what you don't become that hurts."

    You have great potential. When you believe in all you can be, rather than all you cannot become, you will find your place on earth.
