The largest earthquake ( magnitude里氏 9.5) of the 20th century happened on May 22, 1960 off the coast of South Central Chile.

    It generated(生成) one of the most destructive Pacific-wide tsunamis(海啸). Near the generating area, both the earthquake and the tsunami were very much destructive, particularly in the coastal area from Concepcion to the south end of Isla（岛） Chiloe. The largest tsunami damage occurred at Isla Chiloe---the coastal area closest to the epicenter(震中). Huge tsunami waves measuring as high as 25 meters arrived within 10 to 15 minutes after the earthquake, killing at least two hundred people, sinking all the boats, and flooding half a kilometer inland.

    There was large damage and loss of life at Concepcion, Chile's top industrial city. Near the city of Valdivia, the earthquake and following aftershocks generated landslides which killed 18 people. At the port city of Valparaiso, a city of 200,000, many buildings collapsed. A total of 130,000 houses were destroyed --- one in every three in the earthquake zone and nearly 2,000,000 people were left homeless.

Total damage losses, including to agriculture and to industry, were estimated(估计) to be over a half billion dollars . The total number of death related with both the tsunami and the earthquake was never found accurately for the region. Estimates of deaths reached between 490 to 5,7002 with no distinction(差别) as to how many deaths were caused by the earthquake and how many were caused by the tsunami. However, it is believed that most of the deaths in Chile were caused by the tsunami.

   A. 2,000,000      B. between 490 to 57，002     

   C. 200,000        D. it was hard to know.

48．What does the underlined word “collapsed” probably mean ?

   A. was destroyed     B.. caught fire      C. was flooded       D. sank

                                  

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． 【小题1】  It’s not．The problem is what’s happening above ground, not underground, experts say．
【小题2】  They’re rapidly putting up buildings that can’t stand up to earth quakes, scientists believe．
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,  【小题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． 【小题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 【小题5】  “People are paying attention to the violent planet we’re always living on．Come back an another six months 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．
