Unit Five Dreams

Teaching Aims:

In this unit students are required to :

1) get to know some useful information concerning the topic of the reading passages in this unit and to know more about English culture;

2) do some preparation activities such as discussion, group work, etc. to practice their spoken skill and communicative skills;

6) translate some typical sentences into Chinese or English by using some expressions learned in the reading passages to acquire some translating skills and better their translating abilities.

Useful Information

“Dreams surely are difficult, confusing, and not everything in them is brought to pass for mankind. For fleeting (飞逝的，短暂的) dreams have two gates; one is fashioned of horn (牛角) and one of ivory (象牙). Those which pass through the one of sawn (saw: 锯；用锯子切割)ivory are deceptive (欺骗性的), bringing tidings (消息，音讯) which come to nought (无，零), but those which issue from the one of polished horn bring true results when a mortal (凡人，人类) sees them.”

——Ho mer, a Greek writer

While our own understanding of dreams is certainly more complex than that of Homer, there are still many things about

dreams which we do not understand. We know when dreams occur, we know they can be either “good dreams” or “bad dreams”, but there is still much disagreement about what, if any, significance dreams have to our life while we are awake.

The interpretation of dreams has been a favorite activity of people for as long as we have had recorded history. Some of these dream interpreters have become famous, and some, like the European psychologist Sigmund Freud, felt that all dreams have meanings which relate to our personal relationships with family members and friends. Freud felt that many dreams have sexual meanings, but other dream experts reject this idea.

Part One Preparation

1. A Dream Poll

Read the following statements below. Put a tick in the space provided if you agree, and a zero if you don’t.

Dreams can

___ 1) predict the future;

___ 2) warn you of health dangers;

___ 3) seem more real than reality;

___ 4) provide an answer to a problem;

___ 5) present a work of art to a creative mind;

___6) stimulate powerful physical response in the body;

___7) point out personality flaws (缺陷);

___ 8) make you feel good;

___ 9) make you feel very tired;

___10) make you live longer.

Sample

1) I don’t think dreams can predict the future. I never take dreams seriously. To me, dreams are just nonsense. Some people claim that what they dreamed came true. If this is the case, it is only by accident.

2) Dreams can make me feel good. After a good night’s sleep and some sweet dreams, I feel happy and full of energy when I wake up in the morning. But of course, I don’t like terrible dreams which

make me very tired.

2. Talking About Your Dreams

Directions:Work in pairs and discuss your dreams. Base your discussion about dreams on the following questions.

1) Do you have recurring dreams, that is, dreams that you often have?

2) Have you ever wondered about the meanings of your dreams? Do you have any explanation for your dreams?

3) Why do you think people dream?

Sample

A: How often do you dream?

B: I dream almost every night.

A: What sort of dreams do you have? Are they connected to your daily life?

B: Yes, I always dream about things that are connected to daily life. For example, after I play computer games for a long time, I dream of playing computer games. Sometimes, I can’t find a book, but then I dream that I have found it.

A: Do you have recurring dreams?

B: Yes. I often dream of having to take an exam I haven’t prepared for.

A: Have you ever wondered about the meanings of your dreams?

Do you have any satisfactory explanations for your dreams?

B: I am curious about the meanings of my dreams, but I don’t have any explanations for them. Someone told me that if I dream of coffins or water, I will be rich. I did dream of water, but I am still very poor. I ask my parents for money every month.

A: Why do you think people dream?

B: It is hard to say. However, as a Chinese saying goes, we think of something too often and we dream of it during the night. I think when the body is at rest, the minor part of the brain continues to work. That may be the reason why we dream.

Part Three In-Class Reading

Are You a Dreamer?

General Reading

1. Background Information

A.Sigmund Freud (1856-1939)

An Austrian doctor who developed a new system for understanding the way that people’s minds work, and a new way of treating mental illness called psychoanalysis (心理分析). He believed that the bad experiences that people behave as children can affect their mental health as adults, and that by talking to mentally ill people about their past life and feelings, the hidden causes of their illness can be found. He wrote The Interpretation of Dreams and The Ego and the Id. His ideas, especially about the importance of sex, had a very great influence on the way that people thought in the 20th century.

B. Carl Jung (1875-1961)

A Swiss psychiatrist (精神病医师，精神病学家) who studied the importance of dreams and religion in problems of the mind, and divided people into two groups, introverts (格性内向的人) and extroverts (性格外向的人). Jung developed the idea of the collective unconscious (集体无意识：在荣格心理学里指一个社会、一个民族或整个人类共有的头脑中部分无意识状态，是精神遗传的产物，包含诸如科学观、宗教观、伦理观等), the belief that people’s feelings an d reactions are often based on deep memories of human experience in the past. He worked with Sigmund Freud until they had a serious disagreement.

Dream interpretation.

Part II Para.2-3 Scientific facts about dreams and sleep.

Comments：

the first occurring…这部分是分词独立主格结构，对主句起补充说明的作用。( an absolute construction that functions as the complementary part.)

独立主格的构成：

逻辑主语+形容词逻辑主语+副词逻辑主语+名词逻辑主语+介词短语逻辑主语+现在分词

逻辑主语+过去分词逻辑主语+不定式

例如：

1) The two boys gathered their gear and headed for home, stomachs crying for food, backs burning from too much sun, and legs stiff from sitting. (补充说明)

2) There being no taxis, we had to walk home. (原因状语)

3) Weather permitting, we could do the work much better. (条件状语)

1) Wages may well fall to very low levels over the next few decades.

2) Her life might well have been prolonged if she had been taken to hospital sooner.

4. Some people believe that dreams are total nonsense, merely the result of the misfiring of electrical impulses in the brain, while on the other hand, some read great importance into even the simplest of dreams.(Line 32)

Translation: 有些人认为梦纯粹是无稽之谈，仅仅是人脑中电脉冲无的放矢的结果。而另一方面，有些人甚至能从最简单的梦中推断出极为重要的寓意。

Comments:这是一个并列句。连词while 在句中表示对比关系。前一分句讲一些人认为梦什么都不是，只是脑电波的释放。其中merely the result of the misfiring of electrical impulses in the brain 与nonsense 并列作believe后面宾语从句的表语。后一分句讲另一部分人则相反，能从梦中推断出很重要的寓意。

r ead… into… “从······推断出······”

My partner is problematic. He always reads nonexistent meaning into other’s words.

我的搭档是个爱惹麻烦的人。他总是对别人的话无中生有。

5.According to these dictionaries, a dream about drinking wine meant a short life, whereas a dream about drinking water predicted a long life. (Line 41)

Translation:根据这些词典，梦到喝酒意味着短命，梦到喝水则预示着长寿。

Comments:此句中whereas 表示转折和对比。与其意和用法相近的词还有：while, however, but, although, yet, still, in fact, on the other hand, on the contrary。另外，法律文件常有whereas 开头的段落，意为“鉴于”。

例如：Modesty helps one go forward, whereas conceit makes one lag behind.

虚心使人进步，骄傲使人落后。

6. Psychoanalyst and author Kenneth Saunders explains, “Dreams are closely tied up with an individual’s mind and analysis is so open to mistakes or errors.(Line 50) Translation:心理分析家兼作家肯尼斯·桑德斯解释说：“梦与每个人的思维密切相关，分析往往会出错。

Comments: be open to : 容易受到（诱惑、批评、错误等）1) What you said is open to misunderstanding. 你说的话容易让人产生误解。

2) As a student, making noises in the process of lecture is definitely open to criticism.

作为学生，上课时不安静肯定会受到批评。

Exercise:

1)贪婪的人容易受骗。 A greedy man _is open to being cheated .

2)草率的决定往往会招致错误。Hasty decision is open to mistakes.

Summary

In the past few decades, scientific advances still didn’t offer any final answers to the many questions about dreams that continue to puzzle us.

Recordings of human brain waves show that we all go into dream mode when we fall asleep. The main purpose of sleeping may be to allow us to dream—to review our lives, our worries and hopes in a totally different way

The causes of dreams vary. Some dreams may have a simple physiological cause. And some dreams reflect inner fears

that are instantly recognizable. People have sought answers to the meanings of dreams. There are countless books offering dream interpretations. But psychoanalyst and author Kenneth Saunders explains, “Dreams are closely tied up with an individual’s mind.”

3 Describing a Dream

Directions:

Work in pairs and tell each other an interesting, strange or unusual dream that you had or heard of. Share your dreams with the rest of the class and analyze the possible reasons.

Sample

One night, I woke up from a dream to check my watch. It said 1:00 pm and it was very bright outside. I was very scared since that morning was my first day of school for the new semester, and I was supposed to wake up before 7:00 am. Oversleeping to 1:00 pm would have been terrible! I tried to get up and get out of bed. But I was unable to… instead, I went back to sleep again, and continued with my dream.

Finally, I woke up and checked my watch. It was only 5:00 am, two hours before the time for me to get up for class. It was still dark outside. Not until then did I realize that the earlier checking of my watch had happened in a dream.

After reading the text, I think this can be explained as the dreams which reflect inner fears. When one is very fear of being late

for special occasions, the person will be nervous subconsciously. Therefore, he/she dreamed of looking at the watch.

Part Four Writing and Translation

Translation Practice

Dreams Are Soul Talks

As a species, we have yet to unlock the key to our dream worlds. Despite the fact that so many of us see the value in dreaming and wish to be conscious of our activities in the dream dimensions, most of us still feel that we enter some sort of fantasy land when we sleep. While some believe our dream life is as real as waking life and actively seek ways of controlling what occurs while they sleep, few actually make the connection between what happens in waking life and what occurs in sleep.

In the 1990s, it was widely acknowledged by both psychologists and parapsychologists that our dreams contain the content of our daily lives. Therefore, learning to remember and to “mine” our dreams is a very useful process. Throughout history, native communities have deliberately traveled to their dream worlds as a group, to resolve issues, or set directions based on what the group has dreamt the future holds. Many important scientific discoveries can be rooted in events that occurred in the dream world.

梦是心灵的谈话

人类至今尚未开启通往梦的世界的大门。尽管我们很多人意识到做梦的价值，希望了解我们在梦中的活动，但大多数人在睡眠中仍觉得像进入梦幻世界一样。有些人认为梦中的生活跟醒着的生活一样真实，而且在积极寻找方法控制睡眠时的思维活动，然而很少有人会将清醒时发生的事情跟梦中发生的事情联系在一起。

心理学家和心理玄学家在20世纪90年代普遍认为，我们的梦境包含着日常生活的内容。因此，学习记住并“挖掘”梦境是非常有用的。纵观历史，土著居民们就曾特意集体漫游梦境以解决问题，或根据部落所梦见的未来生活设定方向。许多重要的科学发现就来源于梦境中发生的事件。

Writing

A Nightmare

I grew up in the country and life was hard at that time. I used to share a bed with my younger brother. We would often fight for space.

One night, I had a terrible dream. In the dream, our village was occupied by foreign invaders. The invaders were taking away property and children from households. They set houses on fire and killed anyone who did not obey them. I managed to hide in a pile of hay. I could hear my heart thumping when I saw some foreign soldiers coming toward our house.I couldn’t see them clearly because my eyes were covered with hay. I could hear them coming nearer and talking angrily. But I didn’t understand anything that they said. Just then, I realized that one of my arms was not fully covered.

I wanted to hide in it but I dared not move. Then one of the soldiers discovered me. I was almost scared to death. But still I didn’t move. Then I felt a severe pain on my left arm. I was wounded by a soldier with a sword.

I woke up and realized that I had just had a nightmare. But my left arm was hurting. My brother’s leg had been pressing on my arm.

高中英语必修二unit5 music说课稿

高中英语必修二unit5 music说课稿

高中英语必修二unit5 music说课稿 各位老师：大家好！ 作为一名新课标下的英语老师，让学生愉快地、充满自信地走进我的英语课堂，是我最大的愿望，让学生在我的英语课堂上享受快乐和成功是我孜孜以求的。多年来，我为实现自己的梦想和追求不懈地努力着。今天，借此平台，希望各位老师指导我的说课，是我更加自信的完成老师的使命。 一、说教材内容和学情 我说课的内容选自人教版普通高中课程标准实验教科书英语必修二第五单元。本单元的话题是Music，它是中学生日常生活中比较感兴趣的话题之一。它中心话题是“音乐”和“音乐类型”，单元的各项活动的设计都是围绕着以音乐类型和不同音乐对人的影响展开的。而对于音乐和音乐家，这种学生感兴趣的话题、与切身相关的情节，很容易就会引起学生们的极大兴趣，因此他们学习的参与性和积极性也会较高。在引导学生阅读前，让学生对不同种类的音乐的英文说法加以熟悉和理解，开阔的学生的视野。而在阅读后，结合现在学生中普遍存在的“选秀热”这一热点问题，引发学生的反思。 我的教学对象是高一学生。高中生思想逐渐成熟，对美的追求和对成功的渴望也越来越强烈，因此课堂中除了关注语言知识学习和语言技能训练外,更应该注重其内心的理解和个人对事物的看法。 二、三维教学目标 根据《新课程标准》关于总目标的具体描述，结合高一学生实际，我把教学目标设定为以下几个方面： （一）知识目标和能力目标 学习一些相关的单词、短语和句式,特别是关于音乐种类的词汇和表达对音乐感受的词。比如：动词prefer,feel,enjoy,appreciate,find.calm,形容词 relaxed,sleepy,cheerful,energetic,lively。能用英语表达建议、偏好和爱好。 学生熟悉掌握不同的音乐类型。学会灵活运用课文中的句式，自如的表达自己对音乐的理解和感受，并且从更深一层上去把握不同音乐所表达的不同意义。 （二）情感态度 1.熟悉各种音乐形式，了解音乐在人们生活中的重要性，提高音乐修养 2.从谈论“音乐人的成功”入手使学生了解到做什么事都需要付出艰辛的努力。所谓“台上一分钟，台下十年功”，深化学生的德育教育，进一步激发学生学习的动力。 3.通过开展小组活动，指导学生积极与人合作，相互学习，相互帮助，培养其团队精神。（三）学习策略 学生在一定程度上形成自主学习，利用所教句型和所学知识积极与同学进行真实交流，提高交际策略，培养学生的英语思维表达能力。 三、说教学目标和教学重难点 这一课的重点有两点： 1.新课标要求在语言教学的同时必须能够深化学生的德育教育。因此，如何调动学生的积极性，使学生理解成功来之不易本课的重点之一。在教学过程中教师利用多媒体视频介绍音乐人经过多年的准备和磨练终于取的成功的例子启发学生思考自己的人生：要想拥有美好的人

高中信息技术基础教案全集

教科版高中信息技术基础教案全集(必修) 1.1信息及其特征 一、教学内容分析和设计： “信息及其特征”是教育科学出版社的高一《信息技术基础》第一章第一节的内容。由于这个内容理论性较强，如果只是由教师来讲，学生可能会觉得枯燥，所以我准备在教师的引导下，举出现象，让学生进行探讨，然后归纳获得知识。有不足之处由教师或学生来补充。这样能让学生积极参与，活跃课堂气氛，既让学生学到知识，又培养了学生将学习与生活联系的习惯和自主学习的习惯。 二、教学对象分析： 知识的获取者是刚刚升入高中的学生，按照人的成长认知规律，学生对知识的获取开始由感性认识提升到理性认识。对于“信息”这一事物的认识，可以让他们从大量存在的现象中，发现并归纳出他们应该获得的知识。老师在此过程中起着引导的作用。 三、教学目标： 1、知识、技能目标：学生能够列举学习与生活中的各种信息，感受信息的丰富多彩性；举例说明信息的一般特征；培养学生分析问题、解决问题的能力。 2、过程、方法目标：培养学生从日常生活、学习中发现或归纳出新知识的能力。 3、情感态度与价值观目标：让学生理解信息技术对日常生活和学习的重要作用，激发对信息技术强烈的求知欲，养成积极主动地学习和使用信息技术、参与信息活动的态度。 四、教学重点： 1、信息特征的认识。 五、教学难点： 信息的含义。 六、教学方法 本节概念性强，实践性弱。采用讲授法，讨论法。 教学过程 谈话引入：同学们，信息技术这门课程，我们在初中阶段就已经学习。那么下面请同学们说一说，什么是信息？在我们日常生活中，你认为哪些属于信息？（举例） 生1：校园里铃声响，可以告诉我们信息：上课或下课。 生2：观看校运会，可以获得很多运动会赛场上的信息。 生3：从网上可以获得很多信息，如：学习资料、娱乐、新闻报导等。

重庆高中英语必修五 Unit3《Life in the future》全套教案

Unit 3 life in the future说课稿 尊敬的评委： 早上好。今天我说课的主题是必修五第三单元life in the future，第一篇课文First impressions。我准备从教材，学情，教学，学法，教学过程，板书设计六方面来说。 一．说教材 1. 未来生活在必修5中是一个重要话题。本课是一节泛读课，First impressions 讲述了李强如何安全到达“未来世界”以及在“未来”的第一印象。本课在提高学生的阅读能力上起着非常重要的作用。教材设计这样一个话题，不仅是为了提高学生的语言技能，也是为了拓宽学生的视野，激发学生的学习兴趣。 2. 新课标提出：英语课程的学习，既是学生通过英语学习和实践活动，逐步掌握英语知识和技能，提高语言实际运用能力的过程；又是他们陶冶情操、拓展视野、丰富社会经历、开发思维能力和提高人文素养的过程。学习英语是人的发展的一部分，体现更多的人文精神。 的情感，并有自己的见解。 二．说学情 高二的学生已掌握一定的词汇量，也有自己独立的思想，普遍对新鲜事物感兴趣。但大部分学生阅读能力差，对英语缺乏兴趣，也缺乏信心，所以本节课要以增强学习英语的兴趣和自信为出发点，以提高学生的阅读能力为目的。在教学设计上一定要由浅入深，层层递进。设计不同的教学活动让大部分学生参与进来，享受小组合作的快乐。 基于教材和学情分析本课教学目标: 知识目标：让学生理解课文中心大意，并在文中巩固一些重要的词，短语，句子。 能力目标：提高学生的预测，略读，查读，推断等阅读技巧。 情感目标：激发学生学习英语的兴趣，热爱生活，提高小组合作意识。 教学重难点：掌握未来生活与现在生活的不同，提高推断阅读技巧；理解作者对未来生活 三．说教法和学法 在教学中兴趣是最好的老师，在文中巩固词汇才具有生命力，高中提高学生各种阅读技能是重点。新课程还强调学生是学习的主人，教师只是引导者，要让学生积极主动参入。所以我采用了： 1. 多媒体的使用，采用视频情境导入。 2. 略读（借助图片，每段首尾句），（带着中心词）查读，推断（根据课文提供

1. 利用多媒体课件，展示图片，播放音乐，小组赛等形式最大限度地吸引学生的注意力，使学生对学习产生浓厚的学习兴趣。 2.教学环节层次清楚，衔接自然，环环相扣。The Band That Wasn’t是一篇以介绍美国知名乐队组合The Monkees的发展历程为主的文章。教学设计分成四个部分：热身—阅读前—阅读中—阅读后。热身部分学生通过听音乐、口头交流、看图片及游戏等多种形式来了解音乐的形式和风格，由组合SHE的歌曲Super Star导入阅读教学。阅读前呈现The Monkees组合的信息和欣赏其代表作品及学生谈自己对该乐队的初步认识这三个活动组成，为阅读提供背景知识。阅读过程主要通过快速阅读和仔细阅读完成阅读任务来达到阅读教学目标。然后完成课文内容填空，回顾The Monkees发展历程。阅读后展开讨论，引导学生总结本节课所学并谈自己的感受和想法，并复述课文和写一篇自己喜欢歌手和乐队的内容教学设计以阅读理解能力的提高为主要目标，兼顾听、说、写的训练。 3. 采用了新课标提倡的任务型教学途径。在教学设计中设计了多项学习任务，如；跟学英文儿歌谈感受，看图和听音乐配对音乐的形式，读文找主题句，查找细节信息，完成内容填空等，促使学生在整个教学过程中参与各种活动，自主探究，合作学习，真正获得学习成功的乐趣。 教学反思 这堂课基本做到了把课堂让给学生，让学生在自主、合作、探究的气氛中愉快度过，既顺利完成教学任务，又促进其情感教育。这堂课的完成使我感到欣慰，值得我深思。 首先，良好的导入是整个课堂成功的一半，它能够紧紧抓住学生的心理和兴趣，使课堂教学更具趣味性和艺术性。总体来说，这节课的导入是比较成功的，切入点是让学生欣赏音乐，激发了学生的学习兴趣。这不由得让我想起一句话“教有趣，必乐学”。学习兴趣的形成有利于激发学生的学习动机，促进学生智能的发展。 其次，教学内容设计符合本班学生的实际情况，难度适中，尽量满足不同类型和不同层次学生的要求。在任务的设置中应充分考虑学生是否能够完成。本堂课的细节理解部分难度合适，大多数学生都能顺利完成。 再次，只有师生处于平等地位，学生的主体性才能得到发挥；只有使课堂交际化，师生才能融合在智力与情感的交际过程中。在整个教学过程中，我始终坚持以学生为主体实施教学，创设了多种形式的交际活动。 但是，本堂课也还存在一些不足，需要加以改进： 1、由于本堂课任务多，容量大，导致完成任务时间较紧，今后应注意教学步骤间的紧密衔接，充分体现教师主导、学生主体作用。 2、在实现一个个任务的过程中，老师应该对学生加以引导，包括必要的简单示范，帮助学生完成学习任务。

1.1信息及其特征 一、教学内容分析和设计： “信息及其特征”是教育科学出版社的高一《信息技术基础》第一章第一节的内容。由于这个内容理论性较强，如果只是由教师来讲，学生可能会觉得枯燥，所以我准备在教师的引导下，举出现象，让学生进行探讨，然后归纳获得知识。有不足之处由教师或学生来补充。这样能让学生积极参与，活跃课堂气氛，既让学生学到知识，又培养了学生将学习与生活联系的习惯和自主学习的习惯。 二、教学对象分析： 知识的获取者是刚刚升入高中的学生，按照人的成长认知规律，学生对知识的获取开始由感性认识提升到理性认识。对于“信息”这一事物的认识，可以让他们从大量存在的现象中，发现并归纳出他们应该获得的知识。老师在此过程中起着引导的作用。 三、教学目标： 1、知识、技能目标：学生能够列举学习与生活中的各种信息，感受信息的丰富多彩性；举例说明信息的一般特征；培养学生分析问题、解决问题的能力。 2、过程、方法目标：培养学生从日常生活、学习中发现或归纳出新知识的能力。 3、情感态度与价值观目标：让学生理解信息技术对日常生活和学习的重要作用，激发对信息技术强烈的求知欲，养成积极主动地学习和使用信息技术、参与信息活动的态度。 四、教学重点： 1、信息特征的认识。 五、教学难点： 信息的含义。 六、教学方法 本节概念性强，实践性弱。采用讲授法，讨论法。 教学过程 谈话引入：同学们，信息技术这门课程，我们在初中阶段就已经学习。那么下面请同学们说一说，什么是信息？在我们日常生活中，你认为哪些属于信息？（举例）

生1：校园里铃声响，可以告诉我们信息：上课或下课。 生2：观看校运会，可以获得很多运动会赛场上的信息。 生3：从网上可以获得很多信息，如：学习资料、娱乐、新闻报导等。 生4：在报纸上可以了解国内外的信息。 ……师：同学们举的例子非常好。 其实信息在我们日常生活周围无时不在，无处不有，当然，信息不仅存在于我们的周围，同样可以在我们身体内部找到它的影子，如，医生通过听诊器来感知我们的身体内部的变化以确定病因，因此我们可以说信息是用文字、数字、符号、图像、图形、声音、情景、状态等方式传播的内容。 师：信息无处不在，无时不有。信息的存在多种多样，作为万物中的一种，它们同样有着其固有的特性，也就相同的本质。下面我们通过所获取到的信息，找出它们共同的特性。 师：在我们周围存在的信息中,书刊上的文字依附于纸张,颜色依附于物体的表面,老师讲课的声音依附于空气。还有很多的信息，同学们能举出其他的现象吗？ 生：（讨论）我们的体重依附于身体，CD音乐依附于光盘，…… 师：有没有信息是不依附于任何载体而存在呢？ 生：（讨论）找不到。 师：这说明了什么？ 生：（齐）信息必须依附于载体而存在，信息依附的物体多种多样。 师：通过前面的学习知道信息是必须依附某一媒体进行传播的，所以不能独立存在；文字既可以印刷在书本上，也可以存储到电脑中；信息可以转换成不同的载体形式而被存储下来和传播出去，供更多的人分享，而“分享”的同时也说明信息可传递、可存储。 师：（课件演示） 1、载体依附性 （1）信息不能独立存在，需要依附于一定的载体； （2）同一个信息可以依附于不同的媒体。 （3）载体的依附性具有可存储、可传递、可转换特点。
