The opinion of many engineers is that the architects that designed the New York World Trade Center Twin Towers did a good job in designing the buildings. The buildings were safe from the hazards 【S1】at the time. Indeed, they were designed to withstand the force of aircraft that might crash into them. They were not however, designed to withstand the effects of the very high temperatures generated by the 【S2】 of tons of aviation fuel carried by the aircraft.
Steel 【S3】 covered with concrete is the main structural component of the towers and steel loses a lot of structural strength when heated to 1100 degrees Centigrade and beyond, as it was. To 【S4】 the steel the towers beams were coated with a few centimeters of concrete. That insulation was to provide structural 【S5】 for at lease 1 hour of fire. The towers met that test. The south tower lasted 62 minutes. The north; 103 minutes. Tragedy followed when not all could escape prior to the collapse.
Most experts agree that the Twin Towers were very well designed. Many also agree that the people planning the attacks were very 【S6】 and aimed the aircraft at a height that would effect the most damage. The aircraft crash and the resulting fuel fed fires were aimed at about the 90th floor. That was just high enough to insure that the upper floors would weaken with the heat and crack down, dropping into the 【S7】 part of the building.
The mass of the falling top floors created such a falling load that some experts estimates it 【S8】 by 5 to 10 times normal bearing loads. The effect was like a giant hammer, each floor 【S9】 more weight to be born by the next floor down.
Were the Trade Towers well designed? Engineers say yes. But the public refers to the belief that architects will never again design a tall building without considering the effects of terrorist attacks of all 【S10】 kinds. That not only includes the ability of the structure to withstand attack but the means to allow the buildings’ occupants to escape in time to survive.
[A] exceeded [F] shield [K] lightly
[B] ignition [G] remaining [L] knowledgeable
[C] strictly [H] envisioned [M] replace
[D] practical [I] collision [N] potential
[E] integrity [J] contributing [O] happened
选项
答案
H
解析
从句子结构考虑,本空应填一副词或一过去分词作后置定语。选项中的副词有[C]strictly“严格地”和[K]lightly“轻轻地,愉快地”,二者均与句子的语义不符。选项中的过去分词有[A]exceeded,[H] envisioned和[O] happened。exceed意为“超过,胜过”,此处不涉及两者之间的比较,因此排除[A];空前的 hazard指可能导致危险的因察或危险隐患,含有将半时的意味,因此不能用happened作后置定语;envision意为“想象,预想”,能与hazard构成合理的动宾搭配,the hazards envisioned at the time 指“当时能预见到的危险”,因此[H]为答案。
