2019年高中英语 Unit 5 The power of nature教案 新人教版选修6【美文阅读】基拉韦厄火山是世界上最大的活火山体，位于美国夏威夷岛东南部。这座活动力旺盛的活火山，至今仍经常喷发。Mount KilaueaMount Kilauea，the worlds most active volcano，is on the island of Hawaii.It is not far from Manua Loa，the largest volcano in the world.Mauna Loa and Mount Kilauea together form the Volcanoes National Park in Hawaii.Mount Kilauea has produced lava more than fifty times in the last one hundred years.Sometimes the lava moves slowly.At other times it pours out very fast as a huge amount of presure forces it from the volcano.During these times，it moves almost as quickly as water moving down the side of mountain.Sometimes Mount Kilauea produces a large amount of lava that seems like rivers of fire.When the lava from Mount Kilauea reaches the ocean，its fierce heat produces a great amount of steam that rises into the air.The lava is so hot that it continues to burn underwater for some time.The lava from Mount Kilauea continues to add land to the island as the volcanoes of Hawaii have always done.It was these volcanoes that formed the islands of Hawaii.Most of the time the lava of Mount Kilauea seems to move peacefully toward the ocean.Yet it is not as peaceful as it seems from a distance.In recent years the lava destroyed one small town on the island.The boiling rock slowly covered the town.It blocked roads and destroyed them.Nothing can stop the lava of Mount Kilauea.Experts say the volcanoes of Mauna Loa and Mount Kilauea are a serious threat to property(财产)on many parts of the island.They also say the volcanoes of the island of Hawaii are proof that the changing environment of the earth is and will always remain beyond human control.【诱思导学】1Do you think some of lava will keep burning for a while after it flows into the ocean，why?_2What can we infer from the last paragraph?_【答案】1.Yes，it is.Because it is much too hot.2The volcanoes of Mount Kilauea will go on erupting and threaten the island.PeriodPreviewing教学目标本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，对下一堂课课文的全面理解起到一个铺垫作用。教学地位本单元的中心话题是火山、飓风、地震和洪水等自然灾害。听说读写等语言知识和语言技能主要围绕“自然灾害”及如何预防和利用自然灾害这一主题设计的。本单元引导学生讨论这些问题，目的在于让他们了解自然界的威力，认识到人类只有保护自然，才能有效地预防自然灾害并改造和利用自然。新课导入建议通过教材第33页的示意图引导学生了解火山的形成过程和喷发状况，让学生们相互交流有关火山等自然灾害的知识，让学生认识到：尽管自然界有无穷的威力，但只要人类注意保护自然，就能有效地预防自然灾害并改造自然。 教学流程设计学生再次仔细阅读课文(课本第3435页)进行深度理解，并完成“课文缩写”(见学案第75页)。老师布置作业，让学生看课本第3435页并完成课本第35页1、2、3 题，预习学案Period (见学案第7682页), 写一篇关于预防自然灾害方面的习作。.篇章结构阅读P3435的Reading部分，完成下列表格The writers jobTravel to unusual places and work 1._ people from all over the world.Help protect ordinary people from the 2._.Collect information for a 3._ about Mount Kilauea.Help other scientists to 4._ where lava will flow next and how fast.The firstexperienceThe day of the 5._My bed began 6._ and I heard a strange sound.My bedroom became as 7._ as day.Red hot lava 8._ hundreds of metres into the air.The dayafter theeruptionTwo other scientists and I were driven up the mountain and dropped as close as possible to the 9._ that had been formed during the eruption.We slowly 10._to the edge of the crater and looked down into the red，boiling centre.【答案】1.alongside2.volcano3.database4.predict5.eruption6.shaking7.bright8.was fountaining9.crater10.made our way.语篇理解阅读P3435的Reading部分，选择最佳答案1Why did the writer put on special clothes to look at the crater?ABecause he wanted to take some special photos.BBecause he was concerned about his safety.CBecause the other two scientists asked him to.2What bad effect does lava cause?AIt burns the field.BIt buries everything in its path under the molten rock.CIt hardens the field.3How many years has the author worked as a volcanologist?A10 years.B20 years.C30 years.4Where is Mount Kilauea?AIn Alaska.BIn Ohio.

What shall we do when faced with one of these powerful natural forces? Now I want to ask to say something about his/her ways to protect himself/herself from them.(老师让同学谈谈他/她的在自然灾害面前保护自己的一些方法。)教学流程设计让学生就“互动探究”(见学案第7682页)进行讨论，让学生各自发表自己的见解，然后让各个讨论组派代表汇报各自讨论结果。老师针对难点和重点词汇进行讲解，并补充学案中所遗漏的重点词汇，补充一些必要的练习。布置作业。让学生完成课本第36页第1、2、3题，“课时作业”和预习“Period
