After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report: The damage and death toll could have been much worse.
More than 60 people died in this earthquake.(74)
By comparison, an earthquake of similar intensity that shook America in 1988 claimed 25 ,000 victims.
Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4: 31 a. m. on a holiday, when traffic was light on the city’ s highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city’ s buildings and highways, making them more resistant to quakes.
Despite the good news, civil engineers aren ’ t resting on their successes. Pinned to their drawing boards are blueprints for improved quake-resistant buildings.(75)
The new designs should offer even greater security to cities where earthquakes often take place.
In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations. The most recent designs give buildings brains as well as concrete and steel supports. Called smart buildings, the structures respond like living organisms to an earthquake’ s vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction.
The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.
It can be inferred from the passage that in minimizing the damage caused by earthquakes attention should be focused on______.
选项
A、the increasing use of rubber and steel in capital construction
B、the development of flexible building materials
C、the reduction of the impact of ground vibrations
D、early forecasts of earthquakes
答案
C
解析
推理判断题。通读全文可知,在所有方法中最为先进的方法是将计算机用于新型建筑中,而汁算机主要是用于减少摇摆的程度,即减少地面震动的影响。由此可推断C项正确。
