【导语】高二是承上启下的一年，是成绩分化的分水岭，成绩往往形成两极分化：行则扶摇直上，不行则每况愈下。在这一年里学生必须完成学习方式的转变。为了让你更好的学习逍遥右脑为你整理了《高二英语必修五教案《Unit 3 Life in the future》》希望你喜欢！
教案【一】 本教学设计在新课程教学理念的指导下，力求在培养学生的语言知识、知识技能、情感态度、学习策略和文化意识等素养的基础上发展学生综合运用语言的能力，使学生通过观察、体验、探究等主动学习的方法优化英语学习方法，充分发挥自己的学习潜能，形成有效的学习策略。
1. 开展学生活动，发挥主体作用
新课程强调要充分发挥学生在教学过程中的主体作用。本课设计遵循以学生为主体，教师为主导这一教学原则，创设角色扮演情景、激烈讨论提出建议，让学生限度地参与教学过程，尊重学生的主体地位，充分发挥学生在学习过程中的主动性、积极性、创造性，使课堂充满活力。
2. 实施情景教学，统合三维目标
本课设计从教学需要出发，创设情景，进行情景设问、讨论，激起学生的情感体验，激活学生思维，帮助学生迅速、正确地理解和接受知识，并在学习过程中培养其积极进取的科学的人生观及价值观，较好地落实了三维目标。而三维目标是相辅相成、相互渗透的，所以在情景教学的过程中，知识的落实、能力的培养、情感态度价值观的渗透交融在一起，实现了三维目标的和谐与统一。
3. 转变学习方式，增强教学效果
新课程要求提倡自主、合作、探究的学习方式，发挥学生的主体性、能动性和独立性，本课设计通过自学课本，小组讨论，综合分析，角色扮演等活动， 为学生自主学习、合作学习、探究学习提供了空间，使学生体验了自主之乐，合作之趣，探究之悦，促进了学生知识的构建与运用，能力的培养和提高，情感体验和态度、价值观的形成，增强了教学效果。
4. 运用问题教学，启发学生思维
本课设计按照诱思探究理论要求，遵循学生的认知规律，引导学生去发现问题、分析问题和解决问题，从而掌握知识，形成能力，培养品质。通过对文章分析的由浅入深，由易到难，循序渐进，引导学生结合历史现状和教材信息，发挥想象，活化语言，从而达到综合运用英语进行交际的目的。有利于培养学生的思维能力，激发学生的创新精神。
本教学设计贯穿了新的教学理念，体现了课程改革的鲜明特色，在教学内容的重新调整、教材的合理处理、教学思路的设计等方面作了尝试性的突破与创新，具有较强的实践性和操作性。
【教材分析】
本单元教学内容为人教版新课标Module 5 Unit 3 Life in the future。本单元的中心话题是“未来生活”，教材内容为学生提供了想象的空间，旨在培养学生预测未来的能力，通过对现实生活与未来生活的对比，唤醒学生把握现在，珍惜现在，爱护环境，保护自然的意识。
第一篇Reading文章主要讲述主人公Li Qiang在时空旅行前、时空旅行中及时空旅行后的所见所想。第二篇则主要记叙了Li Qiang在太空站认识的两个非常特别的太空生物，并将两个生物的特征进行了对比。两篇阅读文章都是科幻型阅读，旨在唤起学生的想象力，培养学生对未来生活的预测。语法部分则延续了课文内容，通过作者对未来生活态度的讨论引出过去分词做状语及定语的用法，并以短文填空的形式来巩固文章生词的用法。听力部分则描绘了一个拥有高新科技的wonderland,表明了人类对美好生活的追求与幻想，并最终通过口语情景设置锻炼学生综合运用英语的能力与技巧，从而对未来生活进行更细致的预测。
考虑到各部分内容的内在联系，笔者结合教学实际将同一话题不同内容与形式的材料进行了重组，对教材内容、编排顺序等进行了调整、删减和补充，将整个单元设计成四个课时，丰富了教学内容和语言活动形式。

sedan chair ? carriage ? bicycle ? motorcycle ? car ? train ? aeroplane ? space craft
4.Q3: What will the future means of transportation be like? (Time travel)
Well, today we are going to learn a text about time travel.
【设计说明】
由日常问候开启话题，通过提问学生家乡情况导入城镇生活，引出不同的建筑材料及交通工具中的生词;然后总结交通工具的发展历史，预测未来的交通方式，引出跨时空旅行，从而进入阅读文章的处理与学习。(由于考虑到Warming-up中的Transport与Houses, Villages,Towns, 以及Location of settlement的联系不大，可单独提出，因此将Transport的发展变化应用于课文的导入中，这样比较科学自然。)

Q4: What did Li Qiang suffer from?
Q5: How did Li Qiang feel? What makes him feel better?
Q6: Where did they arrive?
【设计说明】
通过几个特殊疑问词，提出以下问题，处理文章第一段。因本篇课文是一篇叙事故事，而记叙文时一般都包括事件发生的人物、时间、地点、事件、原因等关键要素，因此让学生通过阅读寻找上述要素，不仅让学生的阅读具有目的性，而且降低了阅读的难度。
2.During the journey
1) In the capsule:
Climb through the round opening -- comfortable seats -- calming drink -- lay relaxed -- we rose slowly from the ground -- complete the journey -- 1000 years later -- ?

【设计说明】
通过精读课文，了解文章细致内容，按照“时空旅行前，时空旅行中及时空旅行后”的时间线索来处理文章细节。“时空旅行中”又可按照“在太空仓内与在太空仓外”分析文章信息。在此过程中锻炼学生精读的阅读技巧，处理文章生词，并适当地引入几个过去分词做状语及定语的句子，为语法部分的讲解作个铺垫。

【设计说明】
通过设置讨论作者对未来生活持乐观还是悲观态度来复习并提升Reading内容，巩固学生对Reading全文线索的了解与掌握，并通过讨论找出含有过去分词用法的句子来支持各自的观点。(由于Reading中Comprehending部分中关于作者对未来生活所持有的态度的讨论跟语法部分联系紧密，故将其从Reading中剪切，转至语法中作为回顾阅读课，导入新课)完成语法练习后，学生对过去分词作状语和定语的用法有了一定的了解，然后教师将过去分词作状语和作定语的用法系统归纳如下：
过去分词作状语可以表示时间、条件、原因、让步、方式或伴随，有时在其前还可以带上连词，以示明确。
1. 作时间状语。 Once discovered, the enemies were completely wiped out.
2. 作原因状语 Moved by his words, I accepted his present.
3. 作条件状语 United we stand, divided we fail.
4. 作让步状语 Although tired, they continued to work.
5. 作方式或伴随状语 The teacher stood there, surrounded by many students.
注意：
1) 作状语的过去分词通常与句子的主语存在着被动关系，她所表示的动作通常和谓语动词属于同一时间范畴，也可表示先于谓语动词发生的动作。有时为了强调先发生的动作，也可用having been done.
e.g. Having been told many times, he can’t still remember it.
2). 过去分词的逻辑主语要跟主句的主语一致,否则不能用过去分词作状语,应用状语从句。
(误)Checked carefully, some spelling mistakes can be avoided.
(正)If the composition is checked carefully, some spelling mistakes can be avoided.
过去分词作定语或状语时，该分词及修饰成分相当一句定语或状语从句，变为定语从句或状语从句中，该从句应该具备两个特征：1)从句的主语和主句中的先行词一致;2)谓语动词为被动语态形式。

2 Ask the Ss a few random questions to revise future time and introduce the topic of the unit. For example: What lessons do you have this afternoon / tomorrow? Are you going to do anything special this evening? What do you think the weather will be like tomorrow? What are you going to do on Saturday evening? Are you planning to do anything on Sunday?
Step 2 Presentation
SB Page 25, Part 1. Ask questions about the picture, and get Ss to tell you what they think is happening. Teach the new words majority, goods, industry. Read the introduction aloud.
Step 3 Reading
Say Now read the dialogue silently and find out this information: What is being planned at this company? Allow the Ss a few moments to carry out the task. Check the answer. (A new factory may be built.) See if the Ss can guess the meaning of out of work.
Step 4 Dialogue
Speech Cassette Lesson 65. Play the tape of the dialogue for the Ss to listen and follow. Go through the dialogue briefly and make sure the Ss understand it. Ask questions like these: What are people at the company talking about? Who is going to make the decision? Why does the company need to build a new factory? What is the difficulty? Why do some people want the new factory to be built? Why are some people against the new factory? Explain that may have plans expresses uncertainty about the future. Play the tape again. This time the Ss listen and repeat. Then let the Ss practise the dialogue in pairs. You may wish to ask one pair to act the scene in front of the class.
Notes:
a People have been talking of it a lot recently.:
Note the Present Perfect Continuous Tense to express an activity which started in the past and is still continuing.
b I simply don‘t know. =I honestly don’t know.
c Right now =At this moment
d The problem is … it. =Finding land for building the new factory is a problem ( i.e. difficult).
e The majority of people =Most people
f a number of people =quite a lot of people
g out of work =do not have jobs
h But some people … built on. =Some people do not want them to build a factory on good farm land. Note the structure not want something to be done.
i I can see the problem. =I understand the problem.
j is likely to happen =will probably happen
k It‘s quite likely: Quite emphasizes likely and increases the possibility.
Step 5 Practice
SB Page 25, Part 2. Demonstrate how to make sentences from the table, then get a few Ss to make example sentences. Then let the Ss do this exercise in pairs. At the end get Ss to write down 5 sentences from this table in their exercise books.
Step 6 Workbook
Wb Lesson 65, Exx. 1 - 4.
After Ex. 1 is done orally, get the Ss to write the answers in their exercise books.
Both Exx. 2 and 3 should be done in pairs first. Then check the answers with the class. Get Ss to translate the sentences into Chinese and ask them to think if they will be able to put them back into English. Pay attention to the sentence structures.
When doing Ex. 4, warn the Ss not to do word for word translation. Special attention should be paid to the sentence patterns and word order.
Step 7 Consolidation
With a good class you can give the Ss the following phrases and get them to make up a dialogue. Write these phrases on the Bb.
I believe you’re right.
What are the problems then?
What do you think is likely to happen?
Write them up on the Bb and demonstrate with a good S how it is possible to make up a dialogue.
A: I think the company will buy more land.
B: I believe you‘re right.
A: But it isn’t likely that the manager will make a decision soon.
B: What are the problems then?
With an ordinary class, just practise the dialogue in Part 1 again.

（1）大气对太阳辐射的削弱作用：①吸收作用：具有选择性，臭氧吸收紫外线，水汽和二氧化碳吸收红外线。对可见光吸收的很少。②反射作用：云层和颗粒较大的尘埃。云层的反射作用最显著。③散射作用：空气分子或微小尘埃，使一部分太阳辐射不能到达地面。
（2）大气对地面的保温作用：大气吸收地面辐射并产生大气逆辐射（射向地面的大气辐射），把部分热量归还给地面，云层越厚大气逆辐射越强。
5、全球近地面有7个气压带（高低压相间分布），6个风带。
（1）低纬度环流：
①赤道低压带：因为热力作用形成，气流辐合上升，易成云致雨，形成多雨带。常年受其控制形成热带雨林气候（亚马孙平原、刚果盆地、东南亚的马来群岛）
②副热带高压带：因为动力作用而形成，气流在30度纬度上空聚积而下沉，形成少雨带（东亚季风区除外），常年受其控制的地区形成热带沙漠气候（北非的撒哈拉水沙漠、西亚的沙漠、北美美国西部的沙漠、南美智利、秘鲁西部的沙漠、澳大利亚大沙漠）
③信风带：由副高吹向赤道低压的气流，在北半球右偏成东北信风，在南半球左偏成东南信风。
（2）中纬度环流：
④副极地低压带：由来自低纬的暖气流与来自高纬的冷气流相遇运动上升而形成。形成温带多雨带。
⑤中纬西风带：由副高吹向副极地低压带的气流，在北半球右偏成西南风，在南半球左偏成西北风，习惯上叫西风，受其常年控制的地区，在大陆西岸形成温带海洋性气候。（欧洲西部、北美西部如加拿大的温哥华附近、南美南端的安第斯山西侧、澳大利亚南端及塔斯马尼亚岛、新西兰等）
（3）高纬环流：
⑥极地高压带：因为热力作用而形成，冷空气下沉，形成少雨带。不过极地因为气温低，蒸发更少，所以极地属于降水量大于蒸发量的地区，为湿润地区。
⑦极地东风带：由极地高压带吹向副极地低压带的气流，在地转偏向力作用下，北半球右偏成东北风，南半球左偏成东南风。
（4）气压带和风带的移动：△移动的原因：随太阳直射点的移动而动。△移动方向：就北半球而言，大致是夏季北移，冬季南移。
（5）单一气压带或风带作用形成的气候类型：热带雨林气候（赤道低气压带）、热带沙漠气候（副热带高气压带）、温带海洋性气候（中纬西风带）。
（6）气压带、风带移动形成的气候类型：热带草原气候（夏季受赤道低气压带控制，冬季受低纬信风带控制）、地中海气候（夏季受副热带高气压带控制，冬季受中纬西风带控制）。
