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，設計) of a 3D computer maze(迷宮) 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(無意識的) 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(認為) 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(影響) my life?”
The scientists say there may be ways to use this phenomenon(現象) 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.

Happiness is for everyone. You don’t need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.
In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy, too. All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.
Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can’t be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge(向…挑戰)yourself. So you can not always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋轉)door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.
小題1:Those who have big houses may often feel .

A．happy

B．lonely

C．free

A．People who have cars would never like to walk in the open air

B．You can get help from others when you make mistakes

C．You can still be a happy person even if you have little money

Do you like to study in the living room? This is not a good place because it is usually too noisy.

A quiet place will help you only think about one thing, and you will learn better.
Before you begin to study, do not forget to clean your desk. A good desk light is important, too. You’ll feel tired easily if there is not enough light(光線). So you should have a clean and bright lamp. To tell you the truth, the most important is that you should put your heart into your study.

The world is not only hungry but also thirsty for water. This may seem strange to you, since nearly 70% of the earth’s surface is covered with water. But about 97% of that is sea water or salt water. Man can only drink and use the other 3% of fresh water from rivers, lakes, underground and so on. And we can not even use all of that because some of it has been made dirty.
Earth Day is April 22. But on all other days, we must also remember how important water is. The water that we use is the most important natural resource on the earth. Today we face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too.
How do cars and factories make our water dirty? First they pollute the air. Then when it rains, the rain water makes our drinking water dirty. Dirty rain, called acid rain is also bad for plants, animals and buildings. Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to stop wasting water. One of the first steps is to develop ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system (下水道). From there it returns to the sea or goes underground.
But even though every large city reused its water, we would still not have enough. So we should make use of sea water by removing the salt in it. If we can take these steps, fresh water won’t be used up.
小題1:The world is thirsty for water because _______.

A．we don’t have enough fresh water	B．a lot of water goes into sewer systems
C．only 70% of the earth’s surface is water	D．sea water is widely used rather than fresh water

小題2:From this passage, we know acid rain _______.

A．is only bad for living things	B．is not bad for buildings and factories
C．can be produced in factories	D．is bad for people, animals, plants and buildings

小題3:One difficult way we can solve the problem is to _______.

A．use the water with salt in it	B．remove the salt from sea water
C．get water from underground	D．reuse the water in cities

小題4:What is the best title for this passage?

A．Fresh water and sea water	B．A thirsty country
C．The importance of water	D．The world’s water problem
