　　A scientist who developed a way to calculate(计算) how much water is used in the produciton of anything form a cup of coffee to a hamburger was awarded the 2008 Stockholm Water Prize.
　　Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of "virtual water(虚拟水)",a calculation method that has changed the nature of trade policy and research.
　　Allan has written seven books and published more than 100 papers.

阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。

　　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 envisioned(点燃) 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 ignition(点燃)of aviation fuel carried by the aircraft.

　　Steel lightly 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 shield the steel the towers beams were coated with a few centimeters of concrete. That insulation was to provide structural integrity for at least 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 said 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 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 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 refers 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 appealing and elegant appearance until they were destroyed

D．they had the miserable honor of being selected as the target of terrorist attack

2．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 hold stable until all of the people therein 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 make duel changes in the structure

3．As we know from the 3rd paragraph, many people believe that ________.

A. the attack was led by Bin Laden

B．those who directed the attack was better engineers than those who built the towers

C．those we directed the attack know quite a lot about the towers

D．the attack was made spontaneously

4．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 attack
