Napping(小睡) after learning something new could help improve your memory--- as long as you dream, scientists say.

   They found people who dream about a new task do it better on waking than those who do not sleep or do not dream.

Volunteers were asked to learn the layout(布局，设计) of a 3D computer maze(迷宫) so they could find their way several hours later. Those allowed to take a pap and who also remembered dreaming of the task, found their way to a landmark quicker.

   The researchers think the dreams are a sign that unconscious(无意识的) parts of the brain are working hard to process information about the task..

   Dr. Robert Stickgold of Harvard Medical School, said dreams may be a marker that the brain is working on the same problem at many levels.

   Study tips

   Co-author Dr. Erin Wamsley said the study suggests our non-conscious brain works on the things that it deem(认为) are the most important.

   “Every day we are gathering lots of information and new experiences,” she said. “It would seem that our dreams are asking the question, “How do I use this information to inform(影响) my life?”

   The scientists say there may be ways to use this phenomenon(现象) for improving learning and memory. For example, students might be better studying hard before bedtime, or taking a nap after a period of afternoon study.

Long ago ,there lived in Greece a learned man. He was so well known for his good knowledge of almost everything that lots of people from all over the country came to learn from him. The great man taught his students whole-heartedly and answered their questions with great patience.

One day a student asked him, “ My dear teacher, didn’t you say you yourself have many ,many more questions about things than we do? But I think we students have far more than you.”

With a smile on his face, the teacher drew two circles ,one as large as a big cake, the other smaller. Then he said , “Of course, I have learned much more. But it’s wrong to think that a teacher has fewer questions than his students. Now, look at these two circles. The inside of the bigger one is my knowledge of things, and the inside of the smaller one is yours. Out of the circles is what is still unknown to us. Since mine is larger, I have to use the longer line to draw the bigger circle. That means I have more opportunities to face what is still unknown. And that’s why I myself have more questions than you do. The more you learn , the more questions you have. You will never learn enough ,you know.”
