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.

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。
