　　選詞填空練習(xí)題答案解析：

　　1.選M)。此處應(yīng)填名詞，作介詞of的賓語(yǔ)，作為后置定語(yǔ)修飾earthquake，說(shuō)明該名詞是“地震”的自然屬性。選項(xiàng)中的名詞有changes，safety，intensity和security，只有intensity可以表示地震的強(qiáng)度，故選M)。

　　2.選G)。此處應(yīng)填副詞，用來(lái)修飾形容詞less。選項(xiàng)中的副詞有relatively“相對(duì)的”和accordingly“相應(yīng)的”，第一段說(shuō)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?gòu)暮缶渲?ldquo;高速路上的車(chē)輛不是很多”可以推斷：這次的地震造成的“死傷人數(shù)”與1998年比少很多，即少是相對(duì)的，故選G)relatively。

　　3.選A)。空格中要填的詞是本句話中的主語(yǔ)，應(yīng)為名詞。這句話的主干是have strengthened the city’s buildings and highways,從第三段的內(nèi)容和注釋3的解析可知：建筑結(jié)構(gòu)發(fā)生了變化，故應(yīng)選擇A)changes。

　　4.選I)。此處應(yīng)填形容詞，和其前面的more構(gòu)成形容詞的比較級(jí)，描述新型建筑與地震有關(guān)的性能。them = the city’s buildings and highways, have strengthened "被加固"說(shuō)明他們更有抵御風(fēng)險(xiǎn)的能力了。選項(xiàng)中的四個(gè)形容詞只有resistant符合這個(gè)意思，故選I)。

　　5.選B)。此處應(yīng)填形容詞，修飾名詞materials。從后面的...bent without breaking "即使彎曲也不會(huì)折斷"，說(shuō)明是有韌性的材料。選項(xiàng)中的四個(gè)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(yīng)填名詞。根據(jù)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(dòng)對(duì)建筑物的影響"。選項(xiàng)中decrease和reduce都可以表示“減少”的意思，前者指穩(wěn)定的逐步地減少，后者強(qiáng)調(diào)在大小、程度或強(qiáng)度方面下降或減少。故F)reduce更符合題意。

　　7.選D)。根據(jù)注釋3，可以推知，這里要填的詞是和前面的In the past, Laer相對(duì)應(yīng)的，選項(xiàng)中的形容詞中只有recent可表示時(shí)間，the mostrecent desighs“最近的設(shè)計(jì)”，在原文中可以對(duì)應(yīng)“過(guò)去，后來(lái)”，故D)為正確答案。

　　18.選K)。前面提到了智能建筑，這里說(shuō)明當(dāng)?shù)卣鹗惯@樣的建筑向前倒的時(shí)候，電腦會(huì)怎樣它，使它相反方向移動(dòng)。在動(dòng)詞push和force之間懸著。push強(qiáng)調(diào)的是外加的力量，而這里的拖力者是與智能建筑一體的計(jì)算機(jī)系統(tǒng)，故這里force符合文意。

　　9.選N)。此后應(yīng)填名詞，做動(dòng)詞offer的賓語(yǔ)。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(jié)果。抗震型建筑為城市提供的應(yīng)該是更多的安全保障，選項(xiàng)中表示“安全”的詞有safety和security，前者是處于安全狀態(tài)，不受傷害，沒(méi)有危險(xiǎn)，多用于人身，貨物。后者常指國(guó)家社會(huì)的免遭戰(zhàn)爭(zhēng)，災(zāi)難而安然無(wú)恙，故N)security更符合文意。

　　10.選J)。此處應(yīng)填形容詞。從后面的However后的一句說(shuō)明智能建筑的優(yōu)點(diǎn)而得知，However前所說(shuō)的是智能建筑的缺點(diǎn)。既然智能建筑很聰明，又是新事物，那么建造起來(lái)肯定會(huì)耗費(fèi)很多資金的，所以選J)expensive。
