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.

Look at the center circles of Diagram (图) A and Diagram B.  Which of the centre circles looks larger? 

Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram B. In fact , they are exactly the same size.

Then look at the picture on the right. What do you see? A vase ? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time. 

"What's happening? Is something wrong with my eyes?" You may wonder at what you see. Don't worry. Here is how it goes:

When we look at things, our eyes send messages to our brains and then our brains interpret (解读) the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it "Visual illusion" (视觉错误). 

Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of illusions.

1.The centre circle in Diagram A looks smaller than that in Diagram B. That's because           .

A. something is wrong with our eyes

B. the two circles are not the same size

C. our brains interpret the information in a wrong way

D. the two pictures change quickly from one to the other

2.What's the right order according to the passage?

a. We look at things with our eyes.              b. Our brains interpret the messages.

c. Our brains tell us what we have seen.      d. Our eyes send messages to our brains.

A．adbc

B．cabd

C．acdb

D．bcad

3.Movie makers make use of visual illusions to            .

A．help the actors look better

B．make the actors much braver

C．help the actors become stronger

D．make the actors seem different in size

4.In the picture on the right, it seems that Line AB is shorter than Line CD, but in fact Line AB is as long as Line CD. Which paragraph can explain what has happened to our eyes?___________

   

A.The second one.

B.The third one.

C.The fifth one.

D.The sixth one.

5.The text is probably taken from            .

A．an advertisement
