Earthquakes are 1 ; thousands of them happen each day. But most are too weak to feel. During a 2 earthquake, there is often a great noise first. Then the earth 3 terribly; many houses 4 down. Railway tracks break and trains go 5 lines; a great many factories are 6 ; thousands of deaths are caused, and many more lose homes... 7 the great damage and deaths caused by the earthquake 8 , other disasters such as fires often 9 . More buildings are destroyed and more 10 are caused. It is well known of the 11 of a possible earthquake, and for centuries man has been making researches on earthquakes. More than 2,000 years ago, 12 , a Chinese scientist named Zhang Heng 13 a machine which could find out from which 14 the seismic (地震的) waves had come, and this machine is still 15 by scientists today. Now we know much more about earthquakes and 16 they happen, but we still cannot 17 exactly when and where an earthquake will happen, and cannot 18 it from happening. So earthquakes are among the 19 disasters in the world. No one can stop natural earthquakes. 20 , scientists can help stop earthquakes from destroying whole cities and causing too many deaths. |

More and more, professors say, they are coming across 3 students in their classrooms. Many of today"s young scholars (学者) arrive late, leave 4 , talk loud or take care of personal 5 such as paying bills during class. Why are the students behaving badly? "Because they can," said a student of University of North Texas. "A lot of the time, the professors let them get 6 with it." Some educators say it is time to bring politeness back to their classrooms-and even 17 taking some of the blame for bad behavior.

But he was not a good artist. So he invented a very simple camera. He put it in a window of his house and took a picture of his yard. That was the first photograph. The next important date in the history of photography was 1837. That year, Daguerre, another French, took a picture of his studio. He used a new kind of camera and a different process. In his pictures, you could see everything very clearly, even the smallest details. This kind of photograph was called a daguerreotype. Soon, other people began to use Daguerre"s process. Travelers brought back daguerreotypes from all around the world. People photographed famous buildings, cities and mountains. In about 1840, the process was improved. Then photographers could take pictures of people and moving things. The process was not simple. The photographers had to carry lots of films and processing equipment. But this did not stop the photographers, especially in the United States. After 1840s daguerreotype artists were popular in most cities. Mathew Brady was a well-known American photographer. He took many pictures of famous people. The pictures were unusual because they were very life-like and full of personality (个性). Brady was also the first person to take pictures of war. His 1862 Civil War pictures showed dead soldiers and ruined cities. They made the war seem more real and more terrible. In the 1880s, new inventions began to change photography. Photographers could buy films readymade in rolls (卷). So they did not have to make the film themselves. Also, they did not have to process the film immediately. They could bring it back to their studios and develop it later meaning that they did not have to carry lots of equipment. And finally, the invention of the small handheld camera made photography less expensive. With the small camera, anyone could be a photographer. People began to use cameras just for fun. They took pictures of their families, friends and favorite places. They called these pictures "snapshot". Photographs became very popular in newspapers in the 1890s. Soon magazines and books also used documentary photographs. These pictures showed true events and people. They were much more real than drawing. Photography also turned into a form of art by the end of the 19th century. Some photographs were not just copies of the real world. They showed ideas and feelings, like other art forms. | 1.

By trying out ideas and solving problems one by one, they are now getting closer to one answer. One funny idea is that animals might have a built-in compass (指南针). Our earth itself is a big magnet (磁体). So a little magnetic needle that swings freely lines itself with the big earth magnet to point north and south. When people discovered that idea about a thousand years ago and invented the compass, it allowed sailors to navigate (航海) on ocean voyages, even under cloudy skies. Actually the idea of the living compass came just from observing animals in nature. Many birds migrate twice a year between their summer homes and winter homes. Some of them fly for thousands of kilometers and mostly at night. Experiments have shown that some birds can recognize star patterns. But they can keep on course even under cloudy skies. How can they do that? A common bird that does not migrate but is great at finding its way home is the homing pigeon. Not all pigeons can find their way home. Those that can are very good at it, and they have been widely studied. One interesting experiment was to attach little magnets to the birds" heads to block their magnetic sense-just as a loud radio can keep you from hearing a call to dinner. On sunny days, that did not fool the pigeons. Evidently they can use the sun to tell which way they are going. But on cloudy days, the pigeons with magnets could not find their way. It was as if the magnets had blocked their magnetic sense. Similar experiments with the same kind of results were done with honeybees. These insects also seem to have a special sense of direction. In spite of the experiments, the idea of an animal compass seemed pretty extraordinary. How would an animal get the magnetic stuff for a compass? An answer came from an unexpected source. A scientist was studying bacteria that lived in the mud of ponds and marshes. He found accidentally little rod-like bacteria that all swam together in one direction-north. Further study showed that each little bacterium had a chain of dense particles inside, which proved magnetic. The bacteria had made themselves into little magnets that could line up with the earth"s magnet. The big news was that a living thing, even a simple bacterium, can make magnetite. That led to a search to see whether animals might have it. By using a special instrument called magnetometer, scientists were able to find magnetite in bees and birds, and even in fish. In each animal, except for the bee, the magnetic stuff was always in or close to the brain. Thus, the idea of a built-in animal compass began to seem reasonable. | The Magnetic Sense-The Living Compass | 用方框中词或短语的适当形式完成短文。 | communicate with, base, make use of, bring about, latter, such as, identity, number, over time, at present |
