Passage 8
Scientists in the United States have developed a computer program that say could provide an early warming of major earthquakes.The new system is designed to give a warming seconds before an earthquake strikes.
That may not sound like very long.However,it could give people time to get under a table.The flow of electric power or gas could be cut,air traffic controllers could warn away pilots.Even so-called “smart buildings” could be designed to get ready.
Richard Allen of the University of Wisconsin and Hiroo Kananmori of the California Institute of Technology developed the program.They call it the Earthquake Alarm System.A report published in Science magazine describes it.
The system uses a mathematical program to measure information collected by instruments placed across the Los Angeles area.Southern California already has more than 150 stations that measure movements within the ground.The information they collect is sent to a high-speed computer.

答案

1.应该选D吧 it could give people time to get under a table. The flow of electric power or gas could be cut,air traffic controllers could warn away pilots. Even so-called “smart buildings” could be designed to get ready,A说人们可以有时间藏到桌子底下,跟smart buildings没啥关系,B是air traffic controllers （空中交通管制员）该做的,C是后面说到的,再说人们知道这个也没用啊,D跟原文的意思一样The flow of electric power or gas could be cut,就是人有时间去关掉他们.
2.D Richard Allen of the University of Wisconsin and Hiroo Kananmori of the California Institute of Technology developed the program.文中没说这两人的关系,AB不选,从他们的大学所在地Wisconsin和California ,知道他们都在美国的大学.
3.B A不对,C我觉得不对是因为他说Areas directly above the center of the earthquake would have the least warning,least很小,可能没啥用吧.D也不太对.而B原文说another problem is the possibility of false alarms.就是还有问题没解决,所以应该还在发展当中.
4.A The system uses a mathematical program to measure information collected by instruments placed across the Los Angeles area.to measure information 是这个项目的目的,跟A的意思一样.
5.我觉得是C.A report published in Science magazine describes it.
希望能帮到你.
