Things similar continuously happened in Haiti and Chile．Thousands of people were
buried in the earthquake and lost their fives．What if we could have warned them? People are always trying hard to find a way of preventing building collapsing(坍塌)．Better materials and technology help，but are not a solution．Just like humans，a building has its own life circle from “birth” to “death”．If we know when a building is going to collapse，we can repair it in advance or get out before it falls．
Now, scientists at the University of Illinois ha、，e developed a material that turns red before it breaks．The invention could be used in things like climbing ropes，or bridge supports．The secret behind the color-changing material is a type of molecule(分子)．A molecule is a group of atoms held together by chemical bonds(化学键)．Imagine you and your friends standing in a circle，holding hands．Each person stands for one atom，your hands represent the bonds，and the entire circle represents a molecule．If one person lets go of his or her hands，the molecule changes color．The research team put the molecule into a soft material．When the researchers stretched(拉长) the material：it turned bright red a few seconds before it broke into two pieces．
When they repeatedly stretched and relaxed the material，without breaking it，it only turned a little red．
The major problem is，light can get rid of the red color．When the team shone a bright light on the molecule，the broken bond was fixed，and the color disappeared．If bright fight keeps the red color from appearing，the material’s warning system will be useless．Scientists still have a lot of work to do before the color-changing molecule can be used outside the lab．

Every day we experiencc one of the wonders of the world around us without even realizing it It is not the amszing complexity of television. Nor the impressive tcchnology of transport The universal wonder we share and
Experience is our ability to make noises with our mouths, and so transmit ideas and thoughts to each other’s minds. This ability comes so naturally that tend to forget what a miracle（奇迹）it is.
Obviously, the ability to talk is something that marks humans off from animals. Of course, some animals have powers just as amazing. Birds can fly thousands of miles by observing positions of the stars in the sky in relation to the time of day and year. In Nature’s went show, humans are a species of animal that have deve pod their own special act. If we reduce it to basie ferms, it’s a ability for communicating information to ther by varying sounds we make as we breathe out.
Not the to don’t have other powers of communication. Our facia. expressions convey our emotions, such as anger, or jout or disappointment. The way we hold our beads can indicate to others whether we are happy or sad. This is so-called “body language”. Bristling(直立的)fur is an unmistakable warning of attack among many animals. Similarly, the bowed bead or drooping tail shows a readiness to take second place in any animal gathering.
Such a means of communication is a basic mechanism that animals, including human beings, instinctively acquire and display. Is the ability to speak just another sort of instinct? If so, how did human beings acquire this amazing skill? Biologists can readily indicate that particular area of our brain where speech mechanisms function, but this doesn’t tell us how that part of our bodies originated in our biological history.

Modcm inventions have speeded up people’s lives amazingly. Motor-cars cover a bundred miles in little more than an hour. Aireraft cross the world a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every ycar motor-cars are produced which go even faster each new computer boasts（吹嘘）of saving preeious seconds in handling tasks.
All this saves timc, but at a prick.When we lose or gain half a day in speeding aeross the world in an airplane, our bodies tell us so. We get the uncomfoerable feeling known as jet-lag; our bodies feel tlru they have been left bebind in anot ar nine zoors Again pending too long at compulers resul’s in painti ninrts and fingers. Mobile phones also to dange according to some seientists; too much uss may thesmit h bul radiation into our brains, a we do not like to think about.
Howave, what do we do with the time we have saved?Certainly not or so it seems. We are so accustomed to constant activity that we find it difficult to sit and do nothing, or even just one thing at a time. Pcrhaps the days are long gone when we might listen quietly to a story on the radio, letting imavination take us into another world.
There was a time when some people’s lives were devotcd simply to the cultivation of the land or the eare of eattle. No multi-tasking there; their lives wenl on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so ,we must think of the hard tasks our ancestors faeed;:they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modem machinery has freed peope fre that primitive existcnee.

Andy rode slowly on his way to school, day-dreaming about the fishing trip that his father had promised him. He was so busy dreaming about all the fish he would catch that he was unaware of everything else around him.
He rode along until a strange around drew him to the present. He came to a stop and looked curiously up to the heavens. What he saw shocked him. A huge swarm of bees filled the sky like clack cloud and the buzzing mass towards him.
With no time to waste. Andy sped off in the opposite direction, riding furiously without knowing how to escape the swarm. With a rapidly beating heart and his legs pumping furiously, he sped down the rough road. As the bees came closer, his panic increased. Andy knew that he was sensitive to bee stings(蜇). The last sting had landed him in hospital-and that was only one bee sting! He had been forced to stay in bead for two whole days. Suddenly, his father's words came to him. "When you are in a tight situation, don't panic. Use your brain and think your ways out of it. "
On a nearby hill, he could see smoke waving slowly skywards form the chimney of the Nelson family home. "Bees don't like smoke," he thought. "They couldn't get into the house."Andy raced towards the Nelson house, but the bees were gaining ground. Andy knew be could not reach the house in time. He estimated that the bees would catch up with him soon.
Suddenly, out of the corner of his eyes, he spotted a small dam used by Mr. Nelson to irrigate his vegetable garden. Off his bike and into the cool water he dived, disappearing below the surface and away from the savage insects. After holding his breath for as long as he could, Andy came up for air and noticed the bees have gone. Dragging himself out of the date, he struggled up the hilly slope and rang the doorbell. Mr Nelson took his inside and rang his mother.
"You'll really need that fishing break to help you recover,"laughed his mother with relief. "Thank goodness you didn't panic! But Andy did not hear her. He was dreaming once again of the fish he would catch tomorrow. "

Kong Zi. called Confucius(551-479 B. C. ). and Socrates (469-399 B. C. )lived only a hundred years apart, and during their lifetimes there was no contact between China and Greece, but it is interesting on look at how the world that each of there great philosophers came from shaped their ideas, and how these in turn, shaped their societies.
Neither philosopher lived in times of peace, though there were more wars in Greece than in China. The Chinese states were very large and feudal, while the Greek city-states were small and urban. The urban environment in which Socrates lived allowed him to be more radical(激进的)than Confucius. Unlike Confucius, Socrates was not asked by rulers how to govern effectively. Thus Socrates was able to be more idealistic, focusing on issues like freedom and knowledge for its own sake, on the other hand, advised those in government service, and many of his students went on to government service.
Confucius suggested Rule as a principle for the conduct of "Do not do to others what you would not want others to you. "He assumed that all men were equal at birth, though some potential than others, are that it was knowledge that set men apart. Socrates focused on individual, and thought that the greatest purpose of man was to seek wisdom. He believed that some had more potential to develop their reason than others did. Like Confucius, he believed that the superior class should rule the inferior(下层的)classes.
For Socrates, the family was of no importance, and the community of little concern. For Confucius, however, the family was the centre of society, with family relations considered much more important than political relations.
Both men are respected much more today than they were in their lifetimes.
