　　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 earthquakes 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.

　　【答案及詳解】

　　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 citys buildings and highways,從第三段的內容和注釋3的解析可知：建筑結構發生了變化，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 citys 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。

　　6.選F)。此處應填名詞。根據上下文insert rubber and steel between the building and its foundation在建筑物和地基之間填充橡膠和鋼材是為了減少the impact of ground vibrations地面震動對建筑物的影響。選項中decrease和reduce都可以表示減少的意思，前者指穩定的逐步地減少，后者強調在大小、程度或強度方面下降或減少。故F)reduce更符合題意。

　　7.選D)。根據注釋3，可以推知，這里要填的詞是和前面的In the past, Laer相對應的，選項中的形容詞中只有recent可表示時間，the most recent desighs最近的設計，在原文中可以對應過去，后來，故D)為正確答案。

　　8.選K)。前面提到了智能建筑，這里說明當地震使這樣的建筑向前倒的時候，電腦會怎樣它，使它相反方向移動。在動詞push和force之間懸著。push強調的是外加的力量，而這里的拖力者是與智能建筑一體的計算機系統，故這里force符合文意。

　　9.選N)。此后應填名詞，做動詞offer的賓語。本句前面一直在描述新型建筑采取的抗震措施，本句是這些措施的結果。抗震型建筑為城市提供的應該是更多的安全保障，選項中表示安全的詞有safety和security，前者是處于安全狀態，不受傷害，沒有危險，多用于人身，貨物。后者常指國家社會的免遭戰爭，災難而安然無恙，故N)security更符合文意。

　　10.選J)。此處應填形容詞。從后面的However后的一句說明智能建筑的優點而得知，However前所說的是智能建筑的缺點。既然智能建筑很聰明，又是新事物，那么建造起來肯定會耗費很多資金的，所以選J)expensive。
