题文
阅读理解 The opinion of many engineers is that the architects that designed the New York World Trade CenterTwin Towers did a good job in designing the buildings. The buildings were safe from the hazards
envisioned (预想到的) 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
produced by the ignition (点燃) of aviation fuel carried by the aircraft.
Steel lightly covered with concrete is the main structural part of the towers and steel loses a lot of
structural strength when heated to 1100 degrees Centigrade and beyond, as it was. To protect the steel the towers beams were coated with a few centimeters of concrete. That insulation (隔离) was to provide
structural state of being complete for at least 1 hour of fire. The towers met that test. The south tower
lasted 62minutes. The north, 103 minutes. Tragedy followed when not all could escape before the
collapse.
Most experts agree that the Twin Towers were very well designed. Many also agree that the people
planning the attacks were very knowledgeable and aimed the aircraft at a height that would produce 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 remaining part of the building.
The mass of the falling top floors created such a falling load that some experts estimate it exceeded by 5 to 10 times normal bearing loads. The effect was like a giant hammer, each floor contributing more weight
to be born by the next floor down.
Were the Trade Towers well designed? Engineers say yes. But, the public holds to the belief that
architects will never again design a tall building without considering the effects of terrorist attacks of all
potential 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.1. Many engineers believe that the Twin Tower was well-designed after September 11 because _________________.A. it could withstand aircraft crashing into it at the moment
B. it could withstand any natural hazards such as earthquake or fire
C. it had an attracting and beautiful appearance until they were destroyed
D. they had the miserable honor of being selected as the target of terrorist attack2. According to the article, those who designed the tower could have done better if _______.A. the tower lasted longer after being attacked
B. the tower held stable until all of the people in there managed to escape
C. the tower can be immune to such attacks
D. they considered more about the effects of the very high temperatures and made duel(决定性的)
changes in the structure3. The part of the building below 90th floor _____________.A. remained where they were
B. cracked down because of the burning
C. was hammered down by the falling upper part
D. was safe after the attack4. The author believed that the Twin Towers ____________.A. were not well- designed
B. were well-designed
C. were good examples for engineers of our time
D. were out of consideration when we talk about engineering later 题型：未知难度：其他题型

考点
据考高分专家说，试题“阅读理解 The opinio.....”主要考查你对 [日常生活类阅读 ]考点的理解。日常生活类阅读
日常生活类阅读的概念：
日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作，生活以及学习情况。做这一类题时，最主要的是要把握好人物的活动内容，时间和地点。
日常生活类阅读题答题技巧：
【题型说明】
该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小，追根溯源，探索各项风俗的历史渊源，内容有趣。命题也以送分题为主，如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松，试题做起来比较顺手，但绝不能掉以轻心。因为稍不留神，就会丢分。
【备考提醒】
为了保证较高准确率，建议同学们做好以下几点：
1、保持正常的考试心态。笔者在教学中发现，越是容易的试题，同学们越是容易失分。为什么呢？因为在这种情况下，同学们极易产生麻痹思想，认为题目好做，就不引起高度重视，于是思维不发散、不周密。而命题人就是利用同学们的这一弱点，设计陷阱题。所以，无论试题难易与否，我们都要保持正常的考试心态。试题容易，不欣喜；试题难，不悲观。
2、根据前面讲到的方法，认认真真、细细心心做好事实细节题。
3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义，确定多义词或短语在文中的意思，确认文中的某个代词所指代的对象，或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子，切不可望文生义。
4、做好简单推理判断题。简单推理判断题要以表面文字为前提，以具体事实为依据进行推理，做出判断。这种推理方式比较直接，只要弄清事实，即可结合常识推断出合理的结论。
