25、 1/BIts been a hundred years since the last big one in California, the 1906 San Francisco earthquake, which helped give birth to modem earthquake science. A century later, we have a highly successful theory, called plate tectonics, that explains why 1906-type earthquakes happen- along with why conti
26、nents drift, mountains rise, and volcanoes line the Pacific Rim. Plate tectonics may be one of the signature triumphs of the human mind, geologys answer to biologys theory of evolution.Theres the broader question: Are there clear patterns, rules, and regularities in earthquakes, or are they inherent
27、ly random and chaotic? Maybe, as Berkeley seismologist Robert Nadeau says, “A lot of the randomness is just lack of knowledge.“ But any look at a seismic map shows that faults dont follow neat and orderly lines across the landscape. There are places, such as southern California, where they look like
28、 a shattered windshield. All that cracked, unstable crust seethes with stress. When one fault lurches, it can dump stress on other faults. UCLA seismologist David Jackson, a leader of the chaos camp, says the field of earthquake science is “waking up to complexity.“This regular versus chaotic debate
29、 isnt some esoteric academic squabble. Earthquakes kill people. They level cities. The tsunami of December 26, 2004, spawned by a giant earthquake, annihilated more than 220,000 lives. One of the worlds largest economies, Japan, rests nervously atop a seismically rambunctious intersection of tectoni
30、c plates. A major earthquake on one of the faults hidden underneath Los Angeles could kill ten thousand people. A tsunami could smash the Pacific Northwest. Even New York City could be rocked by a temblor.Yet at the moment, earthquake prediction remains a matter of myth, of fabulations in which bird
31、s and snakes and fish and bunny rabbits somehow sniff out the coming calamity. What scientists can do right now is make good maps of fault zones and figure out which ones are probably due for a rupture. And they can make forecasts. A forecast might say that, over a certain number of years, theres a
32、certain likelihood of a certain magnitude earthquake in a given spot. And that you should bolt your house to its foundation and lash the water heater to the wall.Turning forecasts into predictions- “a magnitude 7 earthquake is expected here three days from now“ -may be impossible, but scientists are
33、 doing everything they can to solve the mysteries of earthquakes. They break rocks in laboratories, studying how stone behaves under stress. They hike through ghost forests where dead trees tell of long-ago tsunamis. They make maps of precarious, balanced rocks m see where the ground has shaken in t
34、he past, and how hard. They dig trenches across faults, searching for the active trace. They have wired up fault zones with so many sensors its as though the Earth is a patient in intensive care.Surely, we tell ourselves-trying hard to be persuasive-there must be some way to impose order and decorum
35、 on all that slippery ground.（分数：5.00）(1).Why did the 1906 San Francisco earthquake help give birth to modern earthquake science?（分数：1.00）A.People began to better understand the distribution of shaking and damage.B.Geological experts developed early wanting systems.C.The birth of a highly successful
36、 theory called plate tectonics.D.Geological experts can warn people in advance.(2).What is the significance of plate tectonics?（分数：1.00）A.It explains why 1906-type earth-quakes happen.B.It is a geology theory of evolution.C.It can warn people in advance.D.It marks the birth of modem earthquake scien
37、ce.(3).Why did scientists wire up fault zones with so many sensors?（分数：1.00）A.To stop faults dumping stress on other faults.B.To detect an earthquake.C.To warn people just before a quake.D.To send out electronic signals early to prepare people.(4).How to make the earthquake prediction reliable?（分数：1

39、s is just lack of knowledge.B.We understand earthquakes better than we did a century ago.C.Earthquake prediction remains a matter of myth.D.There must be some way to deal with earthquake.BTEXT 2/BWithin a month of moving to London from Los Angeles in September 2002, Jacob Sager Weinstein started sen
40、ding long e-mails to family and friends under the name “Jacobs London Diary .“I had a few goals,“ Weinstein said recently. “Keeping in touch with family and friends was a major one. But I also wanted to preserve the memories of our experiences in this new country and maintain my writing muscles.“The
41、n out of nowhere, Weinstein said, he began getting requests to be added to the distribution list from people he did not know-usually because someone had forwarded one of his entries.The requests made him start thinking about broadening his audience. So in February 2004 he created his own blog at Uww
42、w. yankeefog. com./U “I usually describe it as the adventures of a comedy writer in London,“ he said. Weinstein said the site attracted about 100 unique visitors a day.Short for Web logs, blogs are little more than Web pages with postings that can be read by anyone using the Internet. Blogs generall
43、y can be updated easily, even by people with no knowledge of HTML coding.Blogs also tend to be written in a more conversational tone than other Web sites and generally allow readers to post their own comments on the site.When blogging began in the early 1990s, they were typically little more than th
44、e authors personal diary. But today blogs can and often do include photos and video, and the subjects range from politics to religion, business to parenting.“In general I think blogging zeroes in on the human desire to be heard, to be seen and to be popular,“ said Shay Harting, chief executive of On
45、fugeO, a California company that helps create video blogs, which are based on uploads of personal videos to Web sites.“It feeds the ego for many people“, Harting said.Weinstein said that even a complete Internet novice could create a blog by using a site like Uwww. blogger. com/U, where a person can
46、 make a few choices from a manu and, voila, a free blog is created.He said that another popular free blogging site can be found at Uwww. livejournal. com/U.He said such sites generally put ads on the blogs that they help create, which is how they make money.Weinstein said that if an author wanted a
47、bit more control over a blog, it would take a little more know-how and money-but not much.“I just downloaded software called Moveable Type, which is free for noncommercial use,“ he said. “I then uploaded it to some computer space that I rent for about $10 a month from a company called Dreamhost. com, followed the instructions that come with Moveable Type to get it runni
