Pre-reading & Reading课文学习A NIGHT THE EARTH DIDN’T SLEEP地球不眠之夜Strange things were happening in the countryside of northeast Hebei. For three days the water in the village wells rose and fell, rose and fell. Farmers noticed that the well walls had deep cracks in them. A smelly gas came out of the cracks. In the farmyards, the chickens and even the pigs were too nervous to eat. Mice ran out of the fields looking for places to hide. Fish jumped out of their bowls and ponds. At about 3:00 am on July 28, 1976, some people saw bright lights in the sky. The sound of planes could be heard 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. But the one million people of the city, who thought little of these events, were asleep as usual that night.河北省东北部的农村在发生奇怪的事情。

但是这个一百万人口的城市，很少有人想到这些事件，那天晚上跟往常一样睡着了。
At 3:42 am everything began to shake. It seemed as if the world was at an end! Eleven kilometres directly below the city the greatest earthquake of the 20th century had begun. It was felt in Beijing, which is more than two hundred kilometres away. One-third of the nation felt it. A huge crack that was eight kilometres long and thirty metres wide cut across houses, roads and canals. Steam burst from holes in the ground. Hard hills of rock became rivers of dirt. In fifteen terrible seconds a large city lay in ruins. The suffering of the people was extreme. Two-thirds of them died or were injured during the earthquake. Thousands of families were killed and many children were left without parents. The number of people who were killed or injured reached more than 400,000.3点42分是一切开始摇晃。

But how could the survivors believe it was natural? Everywhere they looked nearly everything was destroyed. All of the city's hospitals, 75% of its factories and buildings and 90% of its homes were gone. Bricks covered the ground like red autumn leaves. No wind, however, could blow them away. Two dams fell and most of the bridges also fell or were not safe for travelling. The railway tracks were now useless pieces of steel. Tens of thousands of cows would never give milk again. Half a million pigs and millions of chickens were dead. Sand now filled the wells instead of water. People were shocked. Then, later that afternoon, another big quake which was almost as strong as the first one shook Tangshan. Some of the rescue workers and doctors were trapped under the ruins. More buildings fell down. Water, food, and electricity were hard to get. People began to wonder how long the disaster would last.但幸存者怎么可能相信这是自然现象呢？他们看到的地方几乎一切都被摧毁了。

All hope was not lost. Soon after the quakes the army sent 150,000 soldiers to Tangshan to help the rescue workers. Hundreds of thousands of people were helped. The army organized teams to dig out those who were trapped and to bury the dead. To the north of the city, most of the 10, 000 miners were rescued from the coal mines there. Workers built shelters for survivors whose homes had been destroyed. Fresh water was taken to the city by train, truck and plane. Slowly, the city began to breathe again.不是所有的希望都破灭了。
