听力题This is our last meeting before the camps arrive tomorrow. I''ll give u the activity schedule later. But, now I want to answer a question one of u asked me yesterday about camps with asthma. Let me explain a little about the disease. First of all, it''s chronical and very common. 20 million people in the United States alone have it. It affects the bronchial tubes that are the airways of the lungs. During normal breathing, air is drawn in through the mouse and nose, and eventually makes its way into the bronchial tubes. The asthma patient''s bronchial tubes are very sensitive, and easily irritated by exercises or strength, exposure to allergy or pollution, or breathing in cold air, cigarettes smoke. When asthmatic suffers an attack, the airway path was constricted, making it difficult for the person from breathing normally. If a camp in your group has even a mild asthma, you would be informed and given further instruction about what to do in case of an attack. But don''t worry. Some of our camps might have a mild case, but they always bring their medicines with them and we never have a problem. Are there any other questions? Ok, let''s talk about the schedule for tomorrow.

听力题One important thing about art movements is that their popularity can be affected by social conditions, which are themselves often affected by historical events. As an example, look at what happened in the United States early in the 20th century, around the time of the great depression, the art movement known as the Regionalism had begun in the United States even before the depression occurred. But it really flourished in the 1930s, during the depression years. Why? Well, many artists who had been living in big cities were forced by the economic crisis to leave those big cities and move back to their small towns in rural America. Some of these artists came to truly embrace the life in small towns and to eject city life in so called “sophisticated society”. These artists or specifically certain painters really built regionalist movement. They created things in every day life in small towns or farming areas. And their style was not all-neutral, really big glorified or romanticized country life, showing it stable, wholesome, and embodying important American traditions. And this style became very popular, in part because of the economic conditions of the time. You see, the Depression had caused many Americans to begin to doubt their society. But regionalism artists painted scenes that glorified American values, scenes that many Americans could easily identify with. So the movement helped strengthen people’s faith in their country, faith that had weakened as the result of the depression. But in the 1940s, before and after the Second World War, American culture began to take on a much more international spirit, and Regionalism, with its focus on small town life, well, it lost a lot of popularity, as American society changed once again.
