问题 After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report; the damage and death toll (死亡人数) 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 4:31 am. 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 (蓝图) f°r 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 (振动,摆动). 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. [br] The smart buildings discussed in the passage______.

选项 A、would cause serious financial problems
B、would be worthwhile though costly
C、would increase the complexity of architectural design
D、can reduce the ground vibrations caused by earthquakes

答案 B

解析本题仍是一道具体细节题。问文章中提到的智能型建筑如何。此题考查对本文最后一句话的理解。对于安装了电脑的房子，文章的评论主要是造价很高，但防震效果比较好。所以，本题的正确答案应是B“虽然造价高但是值得修建”。
