After the violent earthquake that shook Los Angeles in 1904, 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 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 (蓝图) 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.
1. One reason why the loss of lives in the Los Angeles earthquake was comparatively low is that .
A. new computers had been installed in the buildings
B. it occurred in the residential areas rather than on the highways
C. large numbers of Los Angeles residents had gone for a holiday
D. improvements had been made in the construction of buildings and highways
2. The function of the computer mentioned in the passage is to .
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.
3. The smart buildings discussed in the passage .
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.
4. It can be inferred from the passage that in minimizing the damage caused by earthquakes attention
should be focused on .
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
5. The author's main purpose in writing the passage is to__________.
A. compare the consequences of the earthquakes that occurred in the U.S.
B. encourage civil engineers to make more extensive use of computers
C. outline the history of the development of quake-resistant building materials
D. report new developments in constructing quake-resistant buildings
