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.

“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?”

Nowadays, too much carbon dioxide makes the earth warmer and warmer and causes terrible effect to human beings. To save our planet and ourselves, a new lifestyle called low-carbon life becomes popular. Low carbon means low energy and no waste. It is necessary for everybody to learn to live a low-carbon life.
To live a low-carbon life, we’d better save energy as much as possible. Turn off the lights and TV whenever they are not needed. If possible, use cold water to wash clothes or dishes. Take a short shower and try to take a cold one when the weather gets warm. Don’t do the cooking with electricity.
To live a low-carbon life, we should eat less meat. Everybody knows eating too much meat makes people fat and easy to have heart disease, but maybe you don’t know keeping animals for food produces even more carbon dioxide than all the cars in the world, and being a vegetarian (素食主义者) can help reduce one and a half tons of carbon dioxide a year. Maybe it is a little difficult, but it’s really necessary.
To live a low-carbon life, we are supposed to do less shopping. When we go shopping, we may drive a car or take other transportations (交通工具). On one hand, these machines pollute the air and waste energy. On the other hand, most of us always buy some useless things because of some advertisements. It not only waste money but also causes trouble to the earth, because making everything will produce carbon dioxide more or less.
There are many other ways to live a low-carbon life, such as recycling things, planting trees and reusing textbooks. If we can keep it a habit in our daily life, the earth will become a safer planet for us to live on.

It is well known that everyone has his own dream as well as his own future. But do you know what future really is? I have to say that future is now. That is to say, we must treasure every minute now. If we want to have a bright future, we should know how important time is and use it well.
There is an old English saying, “Gain (得到) time, gain life.” Then what’s time? Time is something that we can’t see or touch, but we feel it passing by. Time is always with us. When we are at table, time passes; when we play, time goes by unnoticeable. We always say “Time is money”, but time is even more precious (珍贵的) than money, because when money is spent, we can make it back. But if time is gone away, it will never return. So, some of us even say time is priceless (无价的).
We should always remember: future is now. For us students, we should try our best to work hard in order to create a great future of our own. We should make the best use of every hour and be the master of today. We should do everything before us as well as possible. And never put off (推迟) what can be done today till tomorrow.
As we all know, “Time and tide wait for no man.” If you waste today, you will regret tomorrow. So from now on, work hard. Tomorrow will be better, and your future will be brighter. Remember: “No pains, no gains.” Today’s hard work is the cause of tomorrow’s harvest.
