8.选K）。前面提到了智能建筑，这里说明当地震使这样的建筑向前倒的时候，电脑会怎样它，使它相反方向移动。在动词push和force之间悬着。push强调的是外加的力量，而这里的拖力者是与智能建筑一体的计算机系统，故这里force符合文意。
9.选N）。此后应填名词，做动词offer的宾语。本句前面一直在描述新型建筑采取的抗震措施，本句是这些措施的结果。抗震型建筑为城市提供的应该是更多的安全保障，选项中表示“安全”的词有safety和security，前者是处于安全状态，不受伤害，没有危险，多用于人身，货物。后者常指国家社会的免遭战争，灾难而安然无恙，故N）security更符合文意。
10.选J）。此处应填形容词。从后面的However后的一句说明智能建筑的优点而得知，However前所说的是智能建筑的缺点。既然智能建筑很聪明，又是新事物，那么建造起来肯定会耗费很多资金的，所以选J）expensive。
导读：
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.(The damage and death toll could have been much worse.此句为虚拟语气，“地震所造成的伤亡和损失本来应该更大。”说明实际上这次地震的损失并不大。)By comparison, an earthquake of similar M)intensity that shook America in 1998 claimed 25,000 victims.（这句的主干是an earthquake...claimed...
25,000 victims。）
Injuries and deaths were G)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 highway. In addition, A)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 I)resistant to quakes.
In the past, making structures quake-resist-ant meant firm yet B)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 F)reduce the impact of ground vibrations. The most D)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 ground shakes and the building tips forward, the computer would K)force the building to shift in the opposite direction. The new designs should offer even greater N)security to cities where earthquakes ofen take place.（In the past...,Later...,The most...designs,这里是一个世间顺序上的描述，说明了从以前到现在，建筑物的结构一直在不断变化。）
The new smart structures could be very J)expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.
全文翻译：
1994年洛杉矶发生强烈大地震后，地震学家报告了一个好消息：地震所造成的伤亡和损害并不大。此次地震有60多人丧生。相较而言，美国1998年发生的相似强度的地震造成的伤亡多达25，000人。
洛杉矶地震伤亡人数相对较少，是因为地震发生在凌晨4：31，而当天是个假日。当时城市公路上的车辆稀少。此外，在过去的20年中洛杉矶市对建筑法规所做的修订使城市的建筑和道路系统更加坚固，增强了抗震能力。 |
