Dreams are expressions of thoughts, feelings and events that pass through our mind while we are sleeping. Everybody dreams. But only some people remember their dreams. Our dreams often include all the senses-smells, sounds, sights, tastes and things we touch. We dream in colour. Sometimes we dream the same dream over and over again. These repeated dreams are often unpleasant. They may even be nightmares-bad dreams that frighten us.
Early in the twentieth century, two famous scientists developed their personal ideas about dreams. Austrian psychiatrist Sigmund Freud published a book called "The Interpretation(诠释) of Dreams" in 1900. Freud believed people often dream about things they want but can't have. These dreams often have something to do with sex and aggression(侵犯). Swiss psychiatrist Carl Jung worked closely with Freud for several years, but he believed dreams could help people grow and understand themselves. He believed dreams provide solutions(解答) to problems we face when we are awake. He didn't believe dreams hide our feelings about sex or aggression. Today we know more about the science of dreaming because researchers can take pictures of people's brains while they are sleeping.
Other researchers are studying how dreaming helps our bodies work with problems and very sad emotions(感情). Robert Stickgold is a professor of psychiatry at Harvard University in Massachusetts. Doctor Stickgold says that when we dream, the brain is trying to make sense of the world. He does not agree with Sigmund Freud that dreaming is the way we express our hidden feelings and desires(愿望).
Scientists believe it is important to keep researching dreams. Doctor Stickgold says it has been more than one hundred years since Sigmund Freud published his important book about dreaming. Yet there is still no agreement on exactly how the brain works when we are dreaming or why we dream.

We live on the earth. We use the sea around us. What do we take from the ocean? And what do we give to it?
We take fishes from the ocean-millions of kilograms of fish, every year, to feed millions of people. We take minerals(矿物) from the ocean. We can get salt by evaporating(蒸发) seawater. Many other minerals, such as gold, can be also got from the sea, but not by simple evaporation. Seaweed(海草) becomes food of many kinds- even candy, and ice cream-as well as medicine. Believe it or not, fresh water is another gift from the sea. We can't drink ocean water. But ocean water becomes fresh water when the salts are removed. In the future, we will find ourselves depending more and more on fresh water from the sea.
The sea gives us food, fertilizer, minerals, water and other gifts. What do we give the sea? We pollute the ocean all the time. 　　Throwing waste into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts more than ever.
We are finally learning that if we destroy our sea, we might also destroy ourselves. Hopefully, it is not too late.
