earthquake scientists had good news to report: The damage and death toll
might have been much worse. More than 60 people died in this earthquake, 1.______
By comparison, an earthquake of similar intensity that shook America in 2,______
1998 claimed 25,000 victims.
    Injuries and deaths were relative less in Los Angeles because the 3.______
quake occurred at 4:31 a.m. in a holiday, when traffic was light on the 4.______
city’s highway. 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 resistible to quakes. 5. ______
    In the past, making structures quake-resistant meant firm yet flexible
materials, such as steel and wood, that bend without breaking. Later, people 6.______
tried to lift a building of its foundation, and insert rubber and steel between 7.______
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; the structures, so called smart buildings, respond like living 8.______
organisms to an earthquake’s vibrations. When ground shakes and the
building tips forward, the computer would force the building to shift in
the direction. The new designs should offer even greater security to cities 9.______
where earthquakes often take place.
    The new smart structures could be very expensive to build, although they 10.______
would save many lives and would be less likely to be damaged during earthquakes.  [br]
选项
答案 of—off
解析 本题为介词误用。根据下文“在建筑物和基座之间插入橡胶和钢铁”，可知上文是将建筑物从基座上提起来，表示分离的介词应当是off.
