听力原文：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.

听力原文：Today most astronomers accept the notion that groups of stars that make up the universe are all moving farther and farther away from each other. but until very recently this idea of an expanding universe was not a theory most European scholars believed in since ancient times and up to about the17th century most of these scholars thought the size of the universe have remained unchanged since the moment of its creation or perhaps forever, with all the stars remaining more or less in place in relation to each other. but that was challenged in the late 17th century by Izic Newton's idea of gravity as a force of attraction, which contradicted the idea of a university that is static, unchanging. If gravity causes all the stars out there in space to attract each other as Newton said, then they could remain motionless. Sooner or later all the stars will fall in absorb each other. well, scientists then propose a new model, taking Newton's theory into account, they didn't want to abandon the idea of motionless stars, but for this model to work, so the stars won't fall in each other, they had to modify Newton's law of gravity, so they theorize that for distance as large as those between stars, the gravitation force repels rather attracts. As you might guess, this other contradictions. But this is prettily resolved in the past centuries by currently accepted theory, which says the universe is continuously expanding. You'll be reading all about that as your homework tonight.
