A Great Quake Coming?
Everyone who lives in San Francisco knows that earthquakes are common in the bav area.Theyhad keen devastating in 1906，for example，a major quake destroyed about 28.000 buildings andkilled hundreds，perhaps thousands of people. Residents now wonder when the next"big one"willstrike.It's bound to happen someday.At least seven active fault(断层)lines run through the SanFrancisco area.Faults are places where pieces of earth's crust(地壳)slide past each other.Whenthese pieces slip，the ground shakes.
To prepare for that day。scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens. One new finding about the 1906 quake is that the San Andreas Fault split apart faster than scientists had assumed at the time.During small earthquakes，faults rupture at about 2.7 kilometersper second.During bigger quakes，however，ruptures can happen at rates faster than 3.5 kilometersper 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 Fancisco，these pressure pulses(脉冲) traveled alway from the city duffng the 1906 event.As bad as the damage was，it could have been farWorse.
Looking ahead，scientists are trying to predict when the next major quake will occur.Records show that earthquakes were common before 1906 event. Since then，the area has been relatively quiet.Pattems 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 qmet for a while.Accoeding to the new research，however，it's not a matter of whether the big one will hit. It's just a matter of when.

答案：
16.A[解析]文章第一段的倒数第三句就说到至少有七条地质断层穿越旧金山而过。
17.C[解析]文章虽然说旧金山大地震的破坏力非常之大，但是没有明确指出其程度是美国历史之最，所以是"not ment：ionecl"。
18.A[解析]文章中说到较大一点的地震其速度至少会超过3500米，而问题为旧金山大地震时断层滑动最快的速度可以到达多少，根据逻辑推断，应该是超过3500米，所以正确。
19.B [解析]文章第五段的第二句话就说到1906年前地震频繁，所以题干错误。
20.B [解析]虽然文章的五、六两段都阐述了科学家们做的积极准备，以及新建建筑物的牢固程度，但之后又话锋一转，说还有84%的老楼不够安全，而在最后一段，也提及人们的心态似乎比较放松，没有较多的忧患意识，因此来判断该题不正确。
