2019-2020年高中英语 Unit 7 The sea教案 北师大版必修3【美文阅读】你对大海了解多少？阳光照耀下她妩媚多姿；狂风暴雨下她凶猛狂暴，除此以外还有什么呢？The first thing to remember is that the sea is very big.When you look at the map of the world you will find there is more water than land.The sea covers three quarters of the world.The sea is also very deep in some places.It is not deep everywhere.Some parts of the sea are very shallow.But in some places the depth of the sea is very great.There is one spot，near Japan，where the sea is nearly 11 kilometers deep！The highest mountain in the world is about 9 kilometers high.If that mountain were put into the sea at that place，there would be 2 kilometers of water above it！What a deep place!If you have swum in the sea，you know that it is salty.You can taste the salt.Rivers，which flow into the sea，carry salt from the land into the sea.Some parts of the sea are saltier than other parts.There is one sea，called the Dead Sea，which is very salty.It is so salty that swimmers cannot sink！Fish cannot live in the Dead Sea!In most parts of the sea，there are plenty of fishes and plants.Some live near the top of the sea.Others live deep down.There are also millions of tiny living things that float in the sea.These floating things are so small that it is hard to see them.Many fish live by eating these.The sea can be very cold.Divers who go deep down in the sea know this.On the top the water may be warm.When the diver goes downwards，the sea bees colder and colder.Another thing happens.When the diver goes deeper，the water above presses down on him.It squeezes (挤)him.Then the diver has to wear clothes made of metal.But he cannot go very deep.Some people who wanted to go very deep used a very strong diving ship！They went down to the deepest part of the sea in it.They went down to a depth of eleven kilometers!【诱思导学】1Why does the author mention the sea somewhere near Japan? 2Are there any fishes living in the Dead Sea? 3Why cant people go very deep in the sea? 【答案】1.To show that the sea in some places is very deep.2No ，there arent.3Because the pressure of the water at great depths is great.Period Previewing(教师用书独具)课标解读本课时主要是通过学生对学案所给内容的学习，了解下一课时即将出现的词汇，初步了解课文以及相关的背景知识，将对下一节课内容的全面理解起到了铺垫作用。教学地位此部分内容是是对下一课时的感悟和预习，合理利用本学案，能大大提升下一课时的课堂效率，有效提升学生学习英语的热情，促进课堂的积极活跃程度，并能在课上能与老师形成较为默契的配合。(教师用书独具)新课导入建议让学生讨论个人与大海的联系，直接导入新课。在设计这堂课时，要从激发学生的对大自然的热爱出发，介绍有关的背景知识，给学生布置具有一定挑战性的任务，让学生以大海人类共同的生存空间为题进行讨论或口头描述。教学流程设计导入新课。学生阅读“美文阅读”与“诱思导学”(见学案第1页)。学生就“美文阅读”进行讨论，统一答案。学生再次阅读课文(课本第8页)并完成“语篇理解”(见学案第2页)。师生共同讨论并统一答案。让学生快速阅读课文(见课本第8页)并完成“篇章结构”(见学案第2页)。学生共同讨论，并让学生发表各自见解，最后统一答案。学生再次仔细阅读课文(课本第89页)进行深度理解，并完成“课文缩写”(见学案第2页)。老师指导学生讨论，共同找出答案。让学生根据所给出的表格进行“自我评估”(见学案第3页)。学生讨论，并让学生代表发表他们讨论得出的答案，老师予以更正。让学生完成“知识初探”部分(见学案第23页)。老师布置作业：让学生看课本第89页并完成课本第89页第1、3题，预习学案Period(见学案第310页)。.篇章结构根据P8的Reading部分，在表格中填入恰当的单词或短语，每空不超过3个单词The Vikings were the first 1. to reach America.Between the 8th and 10th centuries ADThey controlled the seas and coasts of 2. .In 3.
