Scientists who try to predict earthquakes have gotten some new helpers recently—animals.
That’s right, animals. Scientists have begun to understand what farmers have known for thousands of years. Animals often seem to know in advance that an earthquake is coming, and they show their fear by acting in strange ways. Before a Chinese quake in 1975, snakes awoke from their winter sleep early only to freeze to death in the cold air. Cows broke their halters (缰绳) and tried to escape. Chickens refused to enter their cage. All of this unusual behavior, as well as physical changes in the earth, warned Chinese scientists of the coming quake. They moved people away from the danger zone and saved thousands of lives.
One task for scientists today is to learn exactly which types of animal behavior predict quakes. It’s not an easy job. First of all not every animal reacts to the danger of an earthquake. Just before a California quake in 1977, for example, an Arabian horse became very nervous and tried to break out of his enclosure. The Australian horse next to him, however, remained perfectly calm. It’s also difficult at times to tell the difference between normal animal restlessness and “earthquake nerves”. A zoo keeper once called earthquake researchers to say that his cougar had been acting strangely. It turned out that the cat had an upset stomach.
A second task for scientists is to find out exactly what kind of warnings the animals receive. They know that animals sense far more of the world than humans do. Many animals can see, hear, and smell things that people do not even notice. Some can sense tiny changes in air pressure, gravity, or the magnetism of Earth. This extra sense probably helps animals predict quakes.
A good example of this occurred with a group of dogs. They were shut in an area that was being shaken by a series of tiny earthquakes. (Several small quakes often come before or after a large one.) Before each quake a low booming sound was heard. Each boom caused the dogs to bark wildly. Then the dogs began to bark during a silent period. A scientist who was recording quakes looked at his machine. It was acting as though there were a loud noise too. The scientist realized that the dogs had reacted to a booming noise. They also sensed the tiny quake that followed it. The machine recorded both, though humans felt and heard nothing.
In this case there was a machine to monitor what the dogs were sensing. Many times, however, our machines record nothing extraordinary, even though animals know a quake is coming. The animals might be sensing something we measure but do not recognize as a warning. Discovering what animals sense, and learning how they know it is a danger signal, is a job for future scientists.

| D．find out what exact warnings animals sent |
Although Thomas Edison created the technologies behind three major 21st century industries electrical power，recorded music and movies—his greatest invention may have been the modern method of inventing．He basically came up with the modern system of research and development．Edison was not the only scientist doing research in his garage but someone who gathered around him a team of creative scientific minds．Edison’s 1aboratories were the forerunners（先驱）of Apple，Google and Microsoft．
Yet for a11 his scientific gifts，he was no Steve Jobs or Bill Gates．He once said，“Anything that won’ t sell，I don’ t want to invent．” But Edison，unlike Jobs or Gates，had no real sense of what the public wanted or how to change his discoveries into products that might sell．It took him years to understand that the phonograph（留声机）was not a business tool but an entertainment invention．He helped create movies but resisted the idea that people might want to go into a theater to watch one．
We chose Edison this year because we need his example now more than ever．Though we live in a time of great reformation，the U．S．is in danger of losing its advantage in science and technology．American investment（投资）in research and development has not increased as a percentage of GDP since the mid一1980s，while the government’ s share has been dropping．And this is at a time when China is rapidly increasing its money on research and development．The U．S．was once among the 1eading nations．Now it ranks near the bottom of the 23 nations that collect such data．We hope that Edison’ s story might not only encourage reformation but also inspire more
young Americans to study science and engineering．
