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.

Jane was a nurse. When she came to our house with some beautiful flowers in her hand, she smiled and said, “I’m here to help your mother to get well and to cook meals for you. I think we’re going to have a good time together.” 

She looked older to us though her age was about the same as our mother’s. She was not pretty. But she was kind and good. Then she gave us a good meal. After our mother became ill, we never ate such a good one. My brothers and I liked her before we finished the meal.

Our family moved to Australia not long ago. It was difficult for us to live a good life in the new place. Soon our mother became ill and she was in bed.

Every morning father went out to the forest, and worked all day hard as he could. Of course, we tried to help our parents. I cleaned the house and cooked our meals. My older brother learned to grow vegetables.

My two younger brothers were too young to work. Sometimes we went to school. When father came home on that day, he was surprised. Our mother was sleeping peacefully in the bed cleaned by Jane, and there were some beautiful flowers on the table. He said to Jane, “I have no money. I’m sorry I can’t pay you.” Jane said, “Don’t mind, I’m glad to help you. I don’t take money from people who are not happy.”
