Retell the strange things that happend before the earthquake. What did the people in the city react to the strange things? The city’s one million people were asleep as usual that night. At 3:42 a.m., everything began to shake. It seemed as if the world were coming to an end! Eleven kilometres directly below the city, one of the most deadly earthquakes of the 20th century had begun, a quake that even caused damage more than 150 kilometres away in Beijing. Nearly one third of the whole nation felt it! A huge crack, eight kilometres long and 30 metres wide, cut across houses, roads, and waterways. Hard hills of rock became rivers of dirt. In less than one minute, a large city lay in ruins. Two thirds of the people who lived there were dead or injured. Thousands of children were left without parents. The number of people who were killed or badly injured in the quake was more than 400,000. Para. 2 & 3 Damage (Numbers) At 3:42 a.m., everything began to shake.

The number of people who were killed or badly injured in the quake was more than 400,000. How did the numbers show the severe damage during the earthquake? Everywhere survivors looked, there was nothing but ruins. Nearly everything in the city was destroyed. About 75 percent of the city’s factories and buildings, 90 percent of its homes, and all of its hospitals were gone. Bricks covered the ground like red autumn leaves, but no wind could blow them away. Most bridges had fallen or were not safe to cross. The railway tracks were now useless pieces of metal. Tens of thousands of cows, hundreds of thousands of pigs, and millions of chickens were dead. Sand now filled the wells instead of water. People were in shock—and then, later that afternoon, another big quake shook Tangshan again. Even more buildings fell down. Water, food, and electricity were hard to get. People began to wonder how long the disaster would last. Para. 2 & 3 Damage (Numbers) Everywhere survivors looked, there was nothing but ruins. Nearly everything in the city was destroyed.
