英语六级完形填空答案和评析

　　f, humans get serious about avoiding disasters only after one has just smacked them across the face. Well, then, by that logic, 2006 should have been a breakthrough year for rational behavior. With the memory of 9/11, the worst terrorist attack in U.S. history, still fresh in their minds, Americans watched Katrina, the most expensive disaster in U.S. history, on live TV. Anyone who didnt know it before should have learned that bad things can happen. And they are made much worse by our own lack of ambition--our willful blindness to risk as much as our reluctance to work together before everything goes to hell.

　　Granted, some amount of delusion is probably part of the human condition. In A.D. 63, Pompeii was seriously damaged by an earthquake, and the locals immediately went to work rebuilding, in the same spot--until they were buried altogether by a volcano 16 years later. But a review of the past year in disaster history suggests that modern Americans are particularly, mysteriously bad at protecting themselves from guaranteed threats. We know more than we ever did about the dangers we face. But it turns out that in times of crisis, our greatest enemy is rarely the storm, the quake or the surge itself. More often, it is ourselves.
