第三课 Lesson Three 1.地震是地球上的自然现象，让我们准备下列材料来研究地震的成因。 are natural phenomena on the earth. Let's prepare the following materials to study the causes of earthquakes. 2.交流搜集到的地震的资料。 Exchange of seismic data collected. 3.1976年7月28日凌晨3时42分，河北省唐山市的地下传来类似打雷的轰鸣声，大地突然剧烈摇晃，地震爆发了。 At 3:42 a.m. on July 28, 1976, a thunder like roar came from the underground of Tangshan City, Hebei Province. The earth suddenly shook violently and the earthquake broke out. 4.唐山犹如狂风巨浪中的一只小船，这次地震共造成24.2万人死亡。 Tangshan is like a small boat in the strong wind and waves. The earthquake killed a total of 242000 people. 5.2008年5月12日14时28分，四川省发生里氏8.0级强烈地震，全国大半地区有明显震感。 At 14:28 on May 12, 2008, a strong earthquake with a magnitude of 8.0 occurred in Sichuan Province, which was obviously felt in most parts of the country. 6.震中位于阿坝州汶川县，地震造成了严重的生命和财产损失。 The epicenter of the earthquake is located in Wenchuan County, Aba Prefecture, which caused serious loss of life and property. 7.研究地震的成因。 Study the cause of earthquake. 8.实验中的竹片和毛巾相当于什么？ What is the equivalent of bamboo and towel in the experiment? 9.实验告诉我们什么？ What does the experiment tell us? 10.地下岩层在压力的作用下会发生变形。 The underground strata will deform under the action of pressure. 11.当受到的力大到不能承受时，岩层就会发生突然的、快速的断裂。 When the force is too large to bear, the rock will break suddenly and quickly. 12.岩层断裂所产生的地震波传到地表就会引起地表的震动，这就是地震。 The seismic wave generated by rock fracture will cause the surface vibration when it reaches the surface, which is called earthquake. 13.地震来了，我们怎么办？ The earthquake is coming. What shall we do? 14.避震小常识 Common sense of shock absorption 15.地震发生前，常会出现一些异常现象，如地下水位突然改变动物惊慌不安等。 Before the earthquake, some abnormal phenomena often appear, such as the sudden change of groundwater level, animal panic and so on. 16.地震发生时，应立即切断电源、可燃气源，打开选生出口。 When an earthquake occurs, the power supply and combustible gas source should be cut off immediately, and the selective generator outlet should be opened. 17.来不及逃出时，应选择到重心低、结实坚固的家具下躲避，在没有坚固家具可供藏身时，可用坐垫等物品保护好头部。 When there is no time to escape, you should choose to escape under the solid furniture with low center of gravity. When there is no solid furniture to hide, you can use cushions to protect your head. 18.了解地震与人类生活的关系。 Understand the relationship between earthquake and human life. |
