      By late Thurday, 4,900 people were declared homeless after the quake destroyed their homes in a mountainous area lying on the border between Yunnan and Sichuan provinces.

      More dead and injured are expected “as rescuers have yet to reach many faraway areas”.It is very hard for rescue workers because most houses are scattered around the mountains, which are inhabited by Yi and other ethnic minority groups (少数民族)
      The quake hit the area at 5:10 a.m. Beijing time (2,110 Wednesday GMT ). Earthquake regularly affect the two counties, with two quakes measuring 5.0 and 6.2 on the Richter scale killing at least three people and injuring more than 1,500 in Ninglang in November 1998.
      The area is about 100 kilometers from the historic Yunnan town of Lijiang, which was struck in 1996 by an earthquake that killed more than 250 people anf injured 14,000.
      ( Reports from China Daily, May 25, 2001 )

      B. warn the people in mountainous areas in Yunnan to take care of earthquake
      C.call on more help from the people all over the country
      D. analyze why the earthquake took place in this area
      9. After reading the passage we know __________ .
