听力原文： Human beings enjoy challenges. Many of them like physical challenges. They ask themselves questions like these: How fast can I run ？ How high can I climb？ How deep can I dive？ How far can I swim？ How long can I hold my breath？ How much can I lift？ How high can I jump？ Because people enjoy challenges, they like to play sports and watch other people play sports. They like climbing, running, diving, lifting, jumping, and so on. Every four years millions of people all over the world enjoy the international sports competitions called the Olympics.
There are challenges that are not physical challenges. There are social and intellectual challenges, too. Leonardo Da Vinci, who lived in Italy during the fifteenth century, enjoyed every possible challenge. He was an artist and painted the well-known picture, the Mona Lisa. He was an inventor who invented a device to let people breathe under water. He was a scientist, and he learned a great deal about human anatomy.
Another kind of challenge faced the Egyptians between 4,000 and 5,000 years ago when they decided to build the first pyramid. They used six million tons of rock. That is enough to build a ten-foot wall around all of France. Four hundred thousand men worked for twenty years to build it.
So, for thousands of years, people accept challenges. Today we still have many challenges before us. Medical science faces the challenges of conquering the many diseases which still attack human beings. Engineers and planners must build new cities and new kinds of transportation. Scientists must develop new forms of energy. And many of us are interested in the challenge of space. We live in an age of challenge.

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？
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.

听力原文： During a state of deep relaxation, several physiological changes take place in the body: the body's oxygen consumption is reduced; the heart beat decreases; muscle tension and sweating ease, and there is decreased sympathetic nervous system activity. (32) This restful state not only allows the body to repair and restore itself but it has a calming effect on the consciousness. How to achieve this state of relaxation, however, is a matter of opinion. (33) A recent report by Dr. David Holmes of the University of Kansas in the journal American Psychologist said that simple sitting in an armchair has just as many beneficial characteristics for the body as meditation does. Researchers of other relaxation techniques disagree . (34) These experts believe that more structured techniques, such as meditation, lead to a condition of deep relaxation. The debate goes on, but one thing appears to be clear: the relaxation response can be reached by a number of methods, and the methods themselves are not as important as getting there. One day, one method may work best; on another day, an alternative method may be more appropriate. (35) Once you are aware of all the methods, you can find the one that works best for you. Some of the relaxation techniques are meditation, self-analysis and progressive muscle relaxation. Although these techniques may not, in the end, produce more of a relaxation response than just sitting quietly in a chair, (35) they have the added benefit of structure and discipline, and for these reasons appear to be more effective for most individuals.
