Why do we go wrong about our friends--or our enemies？ Sometimes what people say hides their real meaning.And if we don't really listen, we miss the feeling behind the words.Suppose someone tells you, "you're a lucky dog".Is he really on your side？ If he says, "You're a lucky guy" or "You're a lucky gal", that's being friendly.But "lucky dog"？ There's a bit of envy in those words.Maybe he doesn't see it himself.But bringing in the "dog" bit puts you down a little.What he may be saying is that he doesn't think you deserve your luck.
How can you tell the real meaning behind someone's words？ One way is to take a good look at the person talking.Do his words fit the way he looks？ Does what he says square with the tone of voice？ His posture (体态)？ The look in his eyes？ Stop and think.The minute you spend thinking about the real meaning of what people say to you may save another mistake.

Fairy tales were not always intended for children.We know this because some of these stories have existed for hundreds of years and were passed down from generation to generation through songs and drama.They were considered entertainment for everyone, not only for young people.In these ancient stories, the heroes were extremely clever, fiercely independent, and never gave up.Over the years, some of the heroes’ qualities and story lines have been changed to fit the times. Psychologists think that fairy tales have a positive influence on children because they present the two sides of good and evil very clearly.When children hear the stories, they develop sympathetic feelings for the heroic characters.In each tale, they can see that there are many different kinds of people in the world and that we all have a choice about what kind of person we want to be.We can choose to do good actions, rather that bad ones, in our lives.
What kind of values can children learn from fairy tales？ In “The Princess and the Pea,” a poorly dressed girl who insists she is a princess is given a difficult test by the Queen.When she passes the test, we learn that she is rewarded because she stayed true to herself.In “The Little Mermaid,” the mermaid(美人鱼)who lives under the sea longs to be with the humans on land.Through her experiences, we learn about the importance of living with and accepting other cultures.In “Pinocchio,” a wooden puppet(木偶)turns into a boy when he finally learns how to tell the truth. Teaching values is the reason most often given for teaching literature and encouraging reading.These old stories can indeed teach us lessons about human relationships that are universal(普遍的) enough to survive throughout the centuries.This might be the reason why they have been around for so long and are unlikely to disappear any time soon.
