     根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项

为多余选项。

     A 7.0 magnitude (级) earthquake killed more than 230,000 people in Haiti. Then an 8.8 magnitude

quake killed more than 900 people in Chile. And few weeks later, a 6.0 magnitude quake struck rural

eastern Turkey, killing at least 57 people.

     The earthquakes kept coming hard and fast.   1  It's not. The problem is what's happening above

ground, not underground, experts say.

       2  They're rapidly putting up buildings that can't stand up to earth quakes, scientists believer.

     And news reports and better earthquake monitoring make it seem as if earth quakes are increasing all

the time.

     On average, there are 134 earthquakes a year that have a magnitude between 6.0 and 6.9. So far this

year there have been 40 earthquakes-more than in most years for that time period. But that's because the 8.8 quake in Chile caused a large number of strong aftershocks.

     Also, it's not the number of quakes, but their destructive effects that gain attention. The death is largely due to building standards,   3   Paul Earle, a US seismologist, called for better building standards in the

world's big cities.

     Of the 130 cities worldwide with populations of more than I million, more than half are likely to be hit

by earthquakes.   4  "If you have a problem feeding yourself, you're not really going to worry about

earthquakes," said Paul.

     The earthquakes made everyone start to think   5   "People are paying attention to the violent planet

we're always lived on. Come back an another six moths if there has been no earthquakes, most people

will have forgotten it again," said US disaster researcher Dennis Mileti.

A. But it won't last.

B. More people are moving into big cities.

C. Earthquakes don't kill people, buildings do.

D. There have been more deaths overt the past decade from earthquakes.

E. Many people began to wonder if something terrible is happening underground.

F. While it seems as if the are more earthquakes occurring, there really aren't.

G. But developing nations with growing populations don't pay attention to earthquake  preparedness.
