질문 내용 :
어제 제 질문에 답해주신 nanumi0725님, 누들님, ENM DANTE님 감사드립니다^^
그런데 제가 전체 글을 올리지 않아, 문맥 파악하시는 데 감 잡기가 어려우셨던 것 같아서 - 그래서 제 의문도 완전히 해소되지 않은 듯하여ㅠ-전문 올려봅니다.
굳이 다 안 읽으셔도, 색 다르게 한 부분만 읽으셔도 될듯요ㅎ
The Bush administration kicked off a vital two-year investigation this week of the factors that caused the World Trade Center towers to collapse last Sept. 11. It is a necessary follow-up to the initial six-month inquiry into the structural collapse, which was hobbled by a lack of resources and legal authority. The only missing element now is subpoena power for the federal investigators so that they can compel testimony and the production of documents. The House has passed a bill granting that power, and the Senate needs to do likewise.
The initial investigation determined that neither the impact of the huge airliners nor the fireball of jet fuel was enough to bring the towers down. The crucial factor was the extremely hot fires that the jet fuel ignited in the flammable contents of the towers, which softened the structural steel and triggered the collapse. But just which parts of the buildings were critical in the failure has not been determined.
The new investigation, scheduled to last two years and cost some $23 million, will be headed by the National Institute of Standards and Technology, a federal agency with expertise in building performance and structural failures. It will examine such issues as the strength of the steel, how well fireproofing materials worked, why people were trapped on the upper floors and how well firefighters responded. That, in turn, could trigger revisions in building codes and performance standards to make all high-rise buildings safer. One disturbing finding of the initial investigation was that an extremely fierce fire alone could be sufficient to bring down a 47-story building that had not been hit by the planes.
It is unfortunate that the new study is starting so late, when memories have faded and some of the structural evidence has been lost. But the administration is to be commended for putting substantial resources into the inquiry, which could expand into a five-year effort costing more than $50 million for a series of related studies. The construction industry -- and the public -- need to understand the dynamics of these traumatic collapses.
보니까 첫문단에선 과거로, 셋째문단에선 또 미래로, 제 궁금증이었던 마지막 문단에선 현재진행이네요..대충 느낌상으론 물흐르듯이 알것두 같은데요.. 아무래도 여기서 왜 현재진행으로 쓰였는지가 정말 궁금합니다ㅠ도와주세요~!
