When researchers come up with a new
treatment that makes us feel or work better, it’s usually not just the truly

[单项选择] Passage One
Researchers said it was clear that the
world’s oceans play a major role in queuing up rapid climate changes, but that
thus far the mechanics (机制,结构) of such changes were poorly under
stood. "It’s like being blindfolded and walking toward the edge
of a cliff," said Wallace Brocker, a professor of environmental sciences at
Columbia University. "We don’t understand (the factors) so we don’t really know
what to look for." Using ice cores drilled from glaciers and
other ice sheets, the researchers have developed a model showing world
temperatures’ rising and falling with unsettling frequency over the past110 000
years. While some of the changes have been slow and steady, such
as the end of the last Ice Age some 12 000 years ago, others have been swift and
unexpected, such as the rapid warming of the North Atlantic from 19 A. so far we are still almost ignorant of the mechanics of rapid climate changes B. now we are still causing serious damages to the environment C. we are still not sure whether ocean plays a role in causing rapid climate changes D. so far we are still unaware of the possibility of rapid climate changes
