During the years after the terrorist attack on the World Trade Center, structural engineers have been trying hard to solve a question that would otherwise have been completely unthinkable: Can building be designed to stand catastrophic blasts (攻击；爆破) by terrorists?
Soon after the terrorist attacks on the twin towers, structural engineers from the University at Buffalo and the Multidisciplinary Center for Earthquake Engineering Research (MCEER) traveled to ground zero as part of a project funded by the National Science Foundation. They spent two days beginning the task of formulating (构思) ideas about how to design such structures and to search for clues on how to do so in buildings that were damaged, but still are standing.
“Our objective in visiting ground zero was to go and look at the buildings surrounding the World Trade Center, those buildings that are still standing, but that sustained damage,” said Mr. Bruneau, Ph.D. “Our immediate hope is that we can develop a better understanding as to why those buildings remain standing, while our long-term goal is to see whether earthquake engineering technologies can be married to existing technologies to achieve enhanced performance of buildings in the event of terrorist attacks,” he added.
Photographs taken by the investigators demonstrate the monumental damage to the World Trade Center towers and buildings nearby. One building a block away from the towers remains standing, but was badly damaged. “This building is many meters away from the World Trade Center and yet we see a column (柱子) there that used to be part of that building,” explained A. Whittaker, Ph.D. “The column became a missile that shot across the road, through the window and through the floor.”
The visit to the area also brought some surprises, according to the engineers. For example, the floor framing (框架) system in one of the buildings was quite strong , allowing floors that were pierced by tons of falling debris (残砾) to survive. “Good framing systems may provide a simple, but reliable strategy for blast resistance,” he added. Other strategies may include providing alternate paths for gravity loads in the event that a load-bearing column fails. “We also need a better understanding of the mechanism of collapse,” said A. Whittaker. “We need to find out what causes a building to collapse and how you can predict it.”
A. Reinhorn, Ph.D. noted that “earthquake shaking has led to the collapse of buildings in the past. Solutions developed for earthquake-resistant design may apply to blast engineering and terrorist-resistant design. Part of our mission now is to transfer these solutions and to develop new ones where none exist at present.”

第二节 （共5小题；每小题2分，满分10分）

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有2项为多余项。

Sociologists(社会学家), working in western countries, have found that a large number of women wished they had been born men. ______51_______

   “Women often wish they had the same chances as men have, and think it is still men’s world,” said Dr. James Helen, one of the sociologists who did the study.

   ______52_______ A man has to make money to support his family and to make the important decision, so it is right for men to be paid more. Some are even against their wives working at all. ______53_______ If women take full-time jobs, they won’t be able to do what they are best at doing: Making a nice home and bringing up the children.

   Some women disagree. They say they want to get out of their homes, and to have freedom to choose between work and home life. ______54______

   Anne Harper has a very good job. She also believes in  “women’s liberation(妇女解放运动)”. I don’t wish I were a man,” she says, “and I don’t think many women do. But I do wish people would stop treating us like second-class people. At work, for example, we usually do the work that men do but get paid less. There are still a lot of jobs only to men---usually they are the best ones. _______55_______ How many women scientists are there… or engineers?”

A.Many men say that they have more duties than women.

B.Many women say that they have more duties than men.

C.The member is said to be as high as 60% in Germany.

D.Men have the right of equal pay and equal chances.

E.Women have the right of equal pay and equal chances.

F.If you are a man, you have a much better chance of living a wonderful life.

G.When wives go out to work, they say, the home and children can not be taken good care of.

Tom has two cousins, and ______ are engineers.

  Most of the factories under___________ have been designed by Chinese engineers.
