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. At 3:42 am everything began to shake. It seemed as if the world was at an end! Eleven kilometers directly below the city the greatest earthquake of the 20th century had begun. It was felt in Beijing, which is more than two hundred kilometers away. One-third of the nation felt it. A huge crack that was eight kilometers long and thirty meters 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. 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. All hope was not lost. Soon after the quakes, ... 文本解读思路： 1.文本特征 文本提供了标题A Night the Earth Didn’t Sleep，插图（救灾场景）和（4个自然段）的语篇。标题和插图可以帮助读者预测文本主要内容（main idea of the story）。 2.文本特点 1）从文本的内容和结构来看，文章共4段，侧重描写。第一段从时间、空间、事件三个维度呈现地震前的各种征兆和唐山人民的反应。第二段主要从唐山市以及人们两个方面说明了地震后的“一片废墟”的惨烈景象。第三段从建筑、交通、动物、日常生活供给等方面进一步描写地震的强大破坏力。第四段聚焦地震后的救援情况。这样的内容和结构给学生留下了充足的阅读思维空间。 2）从文本的语言来看，文章语言特别地道优美，但难度较大，不仅包含较多的地震相关词汇，比如water in the wells rose and fall, deep cracks, cracked and burst, suffering, in ruins等，而且多次出现各种交际修辞格和审美修辞格，比如标题和结尾最后一句是拟人，使读者能够身临其境，一前一后形成了强烈的对比。第一段sign的部分出现两处rose and fall（重复），形式上精致、工整，升调上富于韵律，能给读者或听话者深刻的印象，同时能以较经济的表达方式突出含义。第二段It seemed as if the world was at an end!是夸张，展现了作者对震后惨烈景象的“悲恸”，这样的语言给学生留下了丰富的写作模仿空间。 3.阅读策略 在文本阅读过程中，使用找读、详读、归纳总结、读前设问等方式对文本进行理解和学习。 课件分享（A）课件分享（B）
