Before the Tangshan Earthquake, Strange things    1    (happen) in the countryside. For several days, the water in the village wells     2       ( rise) and fell. There were deep cracks     3       appeared in the well walls. At least one well had some     4     (smell) gas coming out of it. Chickens and even pigs were too nervous     5     (eat), and dogs refused to go inside buildings.    6     (mouse)ran out of the fields looking for places to hide, and fish jumped out of the water. At about 3:00 a.m.,    7    28 July 1976, bright lights     8     (see) in the sky outside the city of Tangshan and loud noises were heard.       9       the city’s one million people were asleep as usual that night.     10       (fortunately), it led to a lot of people losing their lives.
