听力原文： Today we are going to talk about copyrighting works of art. A copyright is a proof of authorship. It protects artists against someone else using their work without their permission. It's important to remember that United States Copyright Law protects artistic expressions such as paintings, but does not protect any ideas, concept, procedure' or technique. Under the United States Copyright Law, artists need to take several steps to obtain copyright protection. The law was changed in 1978 and again in 1989. For artists the current law means everything they create is automatically and immediately copyrighted. They don't have to file any documents and under the protection of the Copyright Law, any recreations of their original work such as prints are also covered by the artists' copyright. Furthermore, any changes artists made to their original works are covered. The law also makes it clear that when someone buys the work of art, they are not allowed to destroy or change that work of art. Artists keep the copyright even after selling the work of art. The purchaser may buy the physical work, but the right to make prints or copies is still the artists' and buyers does not automatically have any right to make and sell prints or copies of the work. Although works are automatically copyrighted, artists are encouraged to register their work with the United States Copyright Office. Registering art provides additional legal protection and also gives people around the world the ability to approach the owner about licensing and purchasing rights.

听力原文： Some of the most practical lessons coming out of research in psychology are in the area of memory. People ask, why can't I remember that term from the physics chapter or that the library books are due？
For many people, memory may be weak, because they don't use it enough. It's like a muscle. If you don't exercise it, it won't get strong. That's why it's important to keep our mind active, to keep on learning throughout our life. We can do this by reading, playing memory games and seeking out new experiences. It's my guess, though, that the lack of stimulation isn't a problem for students like you. More likely, the lives you live are so busy and stimulating that this in itself may sometimes interfere with learning. Later on I will discuss how information is recalled from memory. But, first, the information needs to be recorded, in other words, learned. And for busy people like you and me, that is where the real problem often lies. If we are distracted, or we are trying to think what we are going to do next, the incoming message just might not be getting recorded effectively. And that leads to the first tip for students who want to improve their memories. Give your full attention to the information you hope to retain. Research clearly shows the advantages of this, and also of active learning, of consciously trying to visualize a new fact, perhaps to make a mental picture, even a wild ridiculous one, so the new fact will stick in our memory. Let me illustrate that for you here a little more concretely this evening.
