问题     After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had news to report: The damage and death toll could have been much worse.
    More than 60 people died in this earthquake. 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 4:3I 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. 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.
The function of the computer mentioned in the passage is to________.

选项 A、counterbalance an earthquake’s action on the building
B、predict the coming of an earthquake with accuracy
C、help strengthen the foundation of the building
D、measure the impact of an earthquake’s vibrations

答案A

解析 本题问在文章中所提及的电脑的功能?去文章中寻找computer, 在倒数第二段的倒数第二行,the computer would force the building to shift in the opposite direction电脑会迫使大楼朝相反的方向变化,这与选项A. counterbalance(相互抵消)an earthquake’s action on a building(相互抵消地震对于一座大楼的活动)相符,故选A。
