　　大学英语四级阅读理解文章精练-7

　　After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report: The damage and death toll could have been much worse. More than 60 people died in this earthquake. By comparison, and earthquake of similar __1__ that shook America in 1998 claimed 25,000 victims.

　　Injuries and deaths were __2__ 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, __3__ made to the construction codes in Los Angeles during the last 20 years have strengthened the city s buildings and highways, making them more __4__ to quakes.

　　In the past, making structures quake-resist-ant meant firm yet __5__ 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 __6__ the impact of ground vibrations. The most __7__ 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 __8__ the building to shift in the opposite direction. The new designs should offer even greater __9__ to cities where earthquakes ofen take place.

　　The new smart structures could be very __10__ to build. However, they would save many lives and would be less likely to be damaged during earthquakes.

　　[A]changes

　　[B]flexible

　　[C]decrease

　　[D]recent

　　[E]push

　　[F]reduce

　　[G]relatively

　　[H]safety

　　[I]resistant

　　[J]expensive

　　[K]force

　　[L]accordingly

　　[M]intensity

　　[N]security

　　[O]opposed

　　Answers：

　　1.选M)。此处应填名词，作介词of的宾语，作为后置定语修饰earthquake，说明该名词是地震的自然属性。选项中的名词有changes，safety，intensity和security，只有intensity可以表示地震的强度，故选M)。

　　2. 选G)。此处应填副词，用来修饰形容词less。选项中的副词有relatively 相对的和accordingly 相应的，第一段说这次地震和1998年的那次地震程度一样，但造成的损失却小很多，再从后句中高速路上的车辆不是很多可以推断：这次的地震造成的死伤人数与1998年比少很多，即少是相对的，故选G)relatively。

　　3.选A)。空格中要填的词是本句话中的主语，应为名词。这句话的主干是have strengthened the city s buildings and highways,从第三段的内容和注释3的解析可知：建筑结构发生了变化，故应选择A)changes。

　　4. 选I)。此处应填形容词，和其前面的more构成形容词的比较级，描述新型建筑与地震有关的性能。them = the city s buildings and highways, have strengthened 被加固说明他们更有抵御风险的能力了。选项中的四个形容词只有resistant符合这个意思，故选I)。

　　5.选B)。此处应填形容词，修饰名词materials。从后面的...bent without breaking 即使弯曲也不会折断，说明是有韧性的材料。选项中的四个形容词只有flexible表示柔韧的，可变形的，故B)正确。

　　6. 选F)。此处应填名词。根据上下文insert rubber and steel between the building and its foundation 在建筑物和地基之间填充橡胶和钢材是为了减少the impact of ground vibrations地面震动对建筑物的影响。选项中decrease和reduce都可以表示减少的意思，前者指稳定的逐步地减少，后者强调在大小、程度或强度方面下降或减少。故F)reduce更符合题意。

　　7.选D)。根据注释3，可以推知，这里要填的词是和前面的In the past, Laer相对应的，选项中的形容词中只有recent可表示时间，the most recent desighs 最近的设计，在原文中可以对应过去，后来，故D)为正确答案。

　　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?？拐鹦徒ㄖ鞘刑峁┑挠Ω檬堑陌踩Ｕ?，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。
