共用题干A Great Quake Coming?
Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area一and they
can be devastating. In 1906,for example,a major quake destroyed about 28,000 buildings and killed
hundreds,perhaps thousands of people.Residents now wonder when the next"Big One"will strike.It's
bound to happen someday. At least seven active fault(断层)lines run through the San Francisco area. Faults
are places where pieces of Earth ' s crust(地壳)slide past each other. When these pieces slip , the ground
shakes.
To prepare for that day,scientists are using new techniques to reanalyze the 1906 earthquake and pre-
dict how bad the damage might be when the next one happens.
One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists
had assumed at the time. During small earthquakes,faults rupture(断裂)at about 2.7 kilometers per second.
During bigger quakes,however,ruptures can happen at rates faster than 3.5 kilometers per second.
At such high speeds,massive amounts of pressure build up,generating underground waves that can
cause more damage than the quake itself. Lucky for San Francisco , these pressure pulses(脉冲)traveled
away from the city during the 1906 event.As bad as the damage was,it could have been far worse.
Looking ahead,scientists are trying to predict when the next major quake will occur. Records show that
earthquakes were common before 1906.Since then,the area has been relatively quiet.Patterns in the data,
however,suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62
percent.
New buildings in San Francisco are quite safe in case of future quakes.Still,more than 84 percent of the
city's buildings are old and weak.Analyses suggest that another massive earthquake would cause extensive
damage.
People who live there today tend to feel safe because San Francisco has remained pretty quiet for a
while.According to the new research,however,it's not a matter of"if" the Big One will hit.It's just a mat-
ter of when.
选项
The San Francisco area is located above several active fault lines.A:RightB:WrongC:Not mentioned
答案
A
解析
第一段提到:至少有7条活跃的断层线穿过旧金山。所以,此处讲“旧金山地区坐落在 数条活跃的断层线上”是正确的。 短文只提到1906年地震的破坏性大,并没说它是最严重的。 从第三段最后一句话可知答案。 第五段第二句提到:记录显示1906年前地震频发。 倒数第二段提到:城里超过84%的建筑是旧的、不坚固的。所以旧金山并未为地震做 好准备。 短文没有谈到这方面的信息。 短文末尾提到:问题已不再是“是否”将会发生大地震,而是“什么时候”会发生。所以, 这一地震是无法避免的。第3部分:概括大意与完成句子
