Venice This iconic city is sinking rapidly.The canals that make up the streets of Venice rise 2mm every year，making relics of history go under the surface of water and destroying architecture.Experts warn that without intervention (干预)，this city will disappear back into the water at an even faster rate，consumed by rising sea level from melting polar ice caps. Machu Picchu These Incan ruins have drawn adventurous tourists into the mountains of South America.The forces of natural erosion have been accelerated by tourism and this landmark faces severe influence from increasing foot traffic.The Peruvian government recently suggested a cable car that would cut out the intense hike up to the ruins，making the site instantly accessible to millions，but the future of Machu Picchu remains uncertain. Glacier National Park Perhaps you've heard that the ice caps are melting.But nowhere is more apparent in the United States than in Glacier National Park.Estimates indicate that the glaciers that are part of the beauty of this national landmark will disappear entirely in the next two decades. The Great Barrier Reef Hidden from view beneath the waves，the Great Barrier Reef has been rapidly dying off.Nearly fifty percent of coral which once occupied a large area is gone，destroyed by pollution and disease. 【语篇解读】本文是应用文，文章主要介绍了世界上濒临消失的几个旅游胜地。

And when the British can't watch the lives of real people，they have another source of entertainment to fall back on－the soap opera.British soap operas are very different to US TV dramas.For one，they are normally longer running.The two most popular，Coronation Street and East-enders，have been running for 48 and 24 years respectively.Both are broadcast several times a week，so remarkably there have been more than 7，000 episodes of Coronation Street. The most obvious difference is that，unlike US dramas，the British soap operas focus on the real world.There is little glamour(魅力)，the stars are rarely rich，and they normally have boring jobs.Perhaps the appeal is that the lives of the characters often mirror the lives of the audience－but with some drama added.This means the viewer can relate to the characters and feel the pain and happiness they go through on the show. Because these soap operas last for decades，the cast is ever changing.The shows rarely focus on one or two main characters.Like the real world，people come and go all the time.However，there are exceptions.Coronation Street's William Roach，76，has played the role of Ken Barlow since the very first episode of the show in 1960，and he is still a regular. The choice of which soap opera you follow is often cultural：people from the north of Britain tend to watch Coronation Street as it is set in Manchester.People from the south generally prefer East-enders，which is set in the east of London.The show is generally considered grittier and is aimed at a younger audience. Unit 3 Look at me 第一课时 教学目标： 1. 能听懂、会说How are you? I'm fine./Fine, thank you等问候语和Let’s go to school邀请别人的句子，掌握Let's talk部分对话内容。 2. 通过创设实际情景，让学生能在相应的情景中准确运用以上句型。 3. 培养学生正确、自然的模仿语音、语调的能力。 4. 培养学生英语学习的良好习惯，激发学生学英语的兴趣。 教学重点：How are you? I’m fine, thank you. 等问候语的学习。 教学难点：1、How are you? 的得体运用。 2、I’m Fine, thank you.中fine 一词字母i 的发音不容易到位。 教具准备： 1、本课Let’s talk/A 的挂图 2、本课时教学配套的录音带，以及歌曲“Hello” “Head, shoulders, knees and toes” 的录音带。 4、Mr. Black, Miss White, Miss Green 的图片。 教学过程： 1 热身、复习(Warm-up/Revision) （1）师播放歌曲“Head, shoulders, knees and toes”，集中学生注意力，调动学生学习兴趣。 （2）游戏Do a game. “SIMON SAYS” 指令可以是一二单元Let’s do (A/B) 的内容。 （3）师生同唱歌曲“Hello”。教师可以边唱边用手势示意学生，将歌曲中的人名改为同班同学的名字。 （4）教师用头饰介绍人物。例如：教师举起Mr. Black的图片说：This is Mr. Black. 然后说：Good morning, I’m Mr. Black. Nice to meet you. 让学生回答：Nice to meet you, too. 用同样的方法介绍Miss White, Miss Green，并要求学生和这些人物打招呼。 2 呈现新课(Presentation) （1）师播放Let’s talk/A的录音，教师边用手势表达对话的内容，既了解了句型的含义，又了解句型运用的情景。 （2）再次播放录音，教师提问：T: What are they doing? 他们在干什么？S: 在打招呼。 （3）教师演示Let’s talk/A的内容，使学生进一步理解对话。方法为：教师左手举起Mike 的图片，右手举起Chen Jie 的图片时，用不同声调引出对话内容。 （4）教师提问：Mike 和Chen Jie 是怎样用英语打招呼的。能力强的学生或学过英语的学生尝试性的说How are you? I’m fine, thank you. （5）听本课时Let’s talk/A教学配套的录音带，学生跟读并模仿发音。 教师注意带读不易掌握的读音，如：I’m fine, thank you. 一句中fine 中的元音字“i” 的读音是[ai] ，提示学生口型要略大些。而thank 一词中的th 在发音时，要让舌尖处于上下齿之间，教师可以夸大口型，让学生了解发音方法。教师要适当纠正，切不可一味的纠正发 水的组成教学设计 一、学情分析 1．水是生命中最重要的物质，是学生非常熟悉的物质。不过，怎样以化学的眼光认识水，学生是陌生和不习惯的。因此，贴近学生的生活实际，从学生身边的一些现象出发，缩小学生对化学学科的距离感，激发学生的学习兴趣，便成了本课题教学设计的核心理念。 2．在本课时的学习中学生存在的困惑也是很突出的，那就是：水通电产生的气体是不是水蒸汽；收集在小试管中的气体接近酒精灯火焰时为什么会发出声音？ 二、教材分析 1．水的组成内容的呈现是模拟史实的研究过程，分水的生成和水的分解两步展开。在此之前首先简要介绍了氢气及其相关的性质，这既是后续学习的必要基础知识，也是模拟水组成研究的开端。水生成的部分由氢气燃烧实验和相关讨论组成，是探究水组成的开始，水分解部分是一个水电解的实验探究。 2．经过水生成和水分解两部分的实验与分析，认识水的组成已经是水到渠成，整个过程将知识的获取、科学过程的体验和科学思想方法的学习融为一体，教育内容丰富，学习情景生动，有利于激发学生的学习积极性。 三、教学目标 1. 知识与技能 （1）了解氢气的性质及验纯的方法。 （2）通过电解水的实验了解水是由氢、氧两种元素组成的。 （3）能从组成上识别氧化物，区别单质和化合物。 2. 过程与方法 通过水的电解实验的观察，了解并体验人类认识水的组成的过程和方法，初步了解利用分解反应的产物来研究纯净物组成的方法。 3. 情感态度与价值观 了解人类认识物质世界的过程和方法，通过学习，保持和增强学生对生活中化学现象的好奇心和探究欲，发展学生学习化学的兴趣。 四、教学重难点 重点：电解水的实验，确定水的组成。 难点：通过电解水实验归纳、分析确定水的组成；对单质、化合物和氧化物概念的理解。 五、学习目标 1．通过本节课的学习,我会知道氢气的一些重要的性质。 2．认识到水是由氢元素和氧元素组成的。 3．在探究性学习的过程中，能主动与同学交流、讨论，清晰的表达自己的观点。 六、教学准备 PPT课件、多媒体设备、集气瓶（两个）、玻璃片（两片）、试管、水电解器、直流电源、小木条等等。 七、教学流程 课时分层作业(十)Section Ⅰ [高考题型练习提能力] Ⅰ.阅读理解 A The evolution(进化) of animals depends upon the environmental conditions on Earth.Here are the top four oldest animal species on Earth. Horseshoe Crab—445 million years old Horseshoe crabs appeared on Earth 445 million years ago.They live in shallow ocean waters across the world.Horseshoe crabs have a long tail.They have nine eyes in total，found throughout the body.Out of the nine，two large eyes are mainly used by horseshoe crabs and the others are used to control their movements. Nautilus—500 million years old The nautilus is a kind of shellfish living in the sea that existed 500 million years ago.That is long before dinosaurs appeared on Earth.It is said to be the only surviving member of a large group of shellfish.Nautiluses live at a depth of 2，200 feet in the ocean. Jellyfish (水母)—550 million years old Jellyfish with an umbrella-like head can be found in every ocean in the world.They have no brain or nervous system.Jellyfish are found in different shapes and colors.The 90 percent of their body weight is water.They are also known to eat other jellyfish.The box jellyfish is the most dangerous species of jellyfish on Earth.

Section A (1a—2c) 三、教材分析 本单元教学以“不明飞行物到达时你在做什么？”导入，围绕“谈论过去发生的事情”这个这个话题展开教学，引导学生通过学习本单元的语言素材看图说话、句型操练、实际描述、对话表演，使学生学会用英语讲故事。这个话题贴近学生的生活，让他们有话可说。本单元的教材特点是话题集中，但句型不多。主要语法内容为when 引导的时间状语从句及过去进行时。 我选取的是本单元的第一个课时，本课出现了大量的地点名词（短语）；一些实意动词；学习过去进行时及when和while 的用法。 四、教学方法 用计算机辅助教学，以任务型教学法为主体，以小组活动，两人协作为依托。以游戏、听力、口头练习和笔头练习为载体开展教学。根据材料的信息,课后完成小短文来检查巩固这节课的知识。 五、教学内容及过程 教学目标：1. Master the key words and phrases . 2. Learn to talk about the past events. 3. Learn to tell a story using the past and past progressive tense. 教学重难点：1.Learn to talk about the past events,using the target language. 2.Master the same and differences between when and while. 3.Can talk about things and tell stories by using the past and past .progressive tense. 课时分层作业(八)Section Ⅱ (建议用时：35分钟) [语言知识练习固基础] Ⅰ.语境填词 A)根据汉语提示，写出下列语句中所缺单词的正确形式 1．He is so stubborn(顽固的)that no one can persuade him to change his mind. 2．What's your attitude(态度)towards his behaviour? 3．How much is the train fare(票价)from Beijing to Shanghai? 4．All these goods will be transported(运输)abroad by ship. 5．I like the way you organize(组织)the information in the report. B)在空白处填入1个适当的单词或括号内单词的正确形式 6．He has enough courage to face the bad situation，which he will never gave in to．7．After a long delay the play finally (final)started. 8．—Is Peter coming? —No，he changed(change)his mind after a phone call at the last minute. 9．It makes me feel good that you care about us. 10．I like getting up early in summer because the morning air is so good to breathe (breathe)． Ⅱ.完成句子 1．我坚持要求他和我们一起参加会议。(insist) I insist that he(should)attend the meeting with us. 2．我昨晚是八点钟去睡觉的。(强调句型) It was at 8 p．m. that I went to bed last night. (教师用书独具) 该题值得关注的是强调句型和when引导的时间状语从句的区别。强调句型结构为“It is/was...that/who...”，把句子中的It is/was和that/who去掉后，如果剩余部分成分完整，则该句子为强调句型。而像“It was 8 p．m. when I went to bed yesterday.”则为时间状语从句，该句可以译为“昨天我去睡觉时已是晚上八点钟了”。2019-2020同步人教英语新课标必修二课时分层作业14 Section+Ⅱ和答案
