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.選M)。此處應填名詞，作介詞of的賓語，作為后置定語修飾earthquake，說明該名詞是“地震”的自然屬性。選項中的名詞有changes，safety，intensity和security，只有intensity可以表示地震的強度，故選M)。
2.選G)。此處應填副詞，用來修飾形容詞less。選項中的副詞有relatively“相對的”和accordingly“相應的”，第一段說這次地震和1998年的那次地震程度一樣，但造成的損失卻小很多，再從后句中“高速路上的車輛不是很多”可以推斷：這次的地震造成的“死傷人數”與1998年比少很多，即少是相對的，故選G)relatively。
3.選A)?？崭裰幸畹脑~是本句話中的主語，應為名詞。這句話的主干是have strengthened the city’s buildings and highways,從第三段的內容和注釋3的解析可知：建筑結構發(fā)生了變化，故應選擇A)changes。
4.選I)。此處應填形容詞，和其前面的more構成形容詞的比較級，描述新型建筑與地震有關的性能。them = the city’s buildings and highways, have strengthened "被加固"說明他們更有抵御風險的能力了。選項中的四個形容詞只有resistant符合這個意思，故選I)。
5.選B)。此處應填形容詞，修飾名詞materials。從后面的...bent without breaking "即使彎曲也不會折斷"，說明是有韌性的材料。選項中的四個形容詞只有flexible表示“柔韌的，可變形的”，故B)正確。
