Strange things were     1     (happen) in the countryside of northeast Hebei. For three days the water in the village wells     2     (rise) and fell. Farmers noticed that the well walls had deep cracks in     3     (they). A smelly gas came out of the cracks. In the farmyards, the chickens and even the pigs were too nervous     4     (eat). Mice ran out of the field     5     (look) for places to hide. Fish jumped out of their bowls and ponds.     6     about 3:00 am on July 28^th, 1976, some people saw     7     (brightly) lights in the sky. The sound of planes could     8     (hear) outside the city of Tangshan even when no planes were in the sky. In the city, the water pipes in some buildings cracked and burst.     9     the one million people of the city,     10     thought little of these events, were asleep as usual that night.
