Unit 3 Australia
（一）教材分析：
本单元的中心话题是“澳大利亚”，主要内容涉及澳大利亚的地理、历史、主要城市、自然风光、野生动植物、风俗习惯等内容。语言技能和语言知识都是围绕这一中心设计的。
热身（Warming-up）部分用几幅关于澳洲的大城市和著名的风景点的图画，过渡到这个单元的课题，并引出与下面阅读课文相关的词汇和背景知识。
读前部分旨在训练学生的阅读技巧，要求学生快速浏览五篇短文后，回答前面的这个部分设计的三个问题。
阅读部分包含五篇主题相同却风格各异的短文，百科全书选段、新闻报道、广告、明信片、旅游手册文章，从多角度概叙了澳大利亚的国家全貌。理解部分由三项练习组成，练习1和“读前”部分相呼应，也是要求学会快速阅读课文，旨在训练略读技巧。练习2要求学生仔细回答仔细细读课文，同时标出自己以前不了解的一些关于澳大利亚的信息，列出其中最有意思的五项，并与同伴交流讨论。这个练习从形式上看比较简单，但他能使学生对文中信息进行主动加工，从认知层面提升到思维层面，从而书本上的知识纳入了自己的知识体系。练习3是对课文内容的拓展，训练学生的逻辑思维能力和表达能力。由于五篇短文大多是陈述性和描叙性的语言，而没有表达个人的观点的语句，因此，该练习借用文中提到的一些事实发问，以激发学生对文章内容的深沉思考。问题的答案不能从文中直接找到，要求学生有理有据地说出自己的观点。
“语言学习”部分由词汇和语法两部分组成。词汇部分练习1匙一个含11个空的语篇，要求学生用课文中出现的生词填空。练习2也是个语篇题，内容是关于澳大利亚早期移民的艰苦生活。这个练习要求学生首先阅读短文，看看其中画线单词是否认识，不要着急查词典，先试试猜一猜的它的意思，并写在“你的释义”一栏中。最后，再查英英词典，将你不认识的单词的定义写在“定义”一栏中。这项练习包含了两种重要的词汇策略：1）根据上下文猜测生词的意思；2）。用英语给英语单词下定义。练习3也包含了两种重要的词汇学习策略。即“学一个记一串”，以一个单词为中心，衍生出与之相关的派生词和合成词。这个练习给予学生充分的联想空间，既巩固了课文生词，又复习了旧词，还通过同伴之间相互交流认识了更多的生词，一举多得。语法部分复习的重点是“表语”。三个练习所用的语篇虽然不同，但任务是一样的，都是要求学生
辨认表语的各种形式。
语言的运用分为“听说”和“阅读讨论” 两部分。听力材料为魏平和他的好友之间的一段对话---鲍勃劝说魏平去野营，但魏平有所顾忌。练习1介绍听力内容发生的背景，并让学生预测魏平为什么对露营敢到紧张，他有可能害怕什么。“阅读讨论”部分的主要内容是关于澳大利亚的几种危险动物展开。
辩论部分提供的题目是：澳大利亚是一个危险的旅游地点。
写作是读写结合的任务型活动。而这一任务又是前面“阅读”和“辩论”的延续。学生通过前面部分获得的有关澳大利亚危险野生动物信息和“辩论”部分的总结，自己对“露营是否安全”这一问题给予回答。

Ⅳ. Teaching methods:
Inductive and deductive methods, task-based learning and cooperative learning
Ⅴ. Teaching aids:
A computer, a blackboard
Ⅵ. Teaching procedures:
(Pre-class)
1.Get the Ss to collect some pictures of Australia and describe them respectively
Step Ⅱ Revision and lead in
1.Ask the students to recall what they’ve learned in the previous reading passage(five
short texts in the Reading part)
2.Ask them a group of questions:
Where is Australia?
How do you like Australia? Use several Adjectives to describe it.
Do you think Australia is a wonderful tourist destination?
How would you feel if you offered a chance to tour around Australia?
Then write down Ss’ answers, of course each answer contains a predicative, so underline them, thus lead in today’s main focus---grammar point the predicative.
Step Ⅲ Discovering the rules
1. Ask the Ss to turn to page 26 and underline all the predicatives in Exercise 1 &
Exercise 2. In Exercise 2, have a pair of Ss to act out the dialogue.
2. Then check answers.
3. Ask them to summarize what can function as predicatives in sentences.
So, together with the Ss we work out that adj, noun, pronoun, numeral, adv, prepositional phrases，infinitives, -ing, -ed, clauses can function as predicatives. Step Ⅳ Further Explaining
1.表语Predicative
表语是由系动词引导的主语补足语，补充说明主语。常见的系动词有：be become feel grow prove smell taste appear get go remain sound seem stay keep
２．充当表语的成分有形容词、名词、代词、数词、副词、介词短语、词组、不定式、－ing 形式、过去分词、从句等。
3．形容词作表语，用来修饰说明主语, 例如:
You don’t feel well today. Are you sick?
4．形容词只能作表语，不能作定语，如：
afraid asleep ready unable alive
aware glad sorry well alone sure
可以说“She felt glad.” 但不能说“a glad woman”.
5. 名词或名词词组作表语，一般用来确定主语的性质，或者表达主语的看法，例
如：
He became a doctor.
Boys are boys.
He’s not the right man for the job.
She seemed an ideal wife for him.
6. 可以接不定式的系动词有：
be appear prove seem
例如：
They only aim was to get success.
She appears to have many beautiful dresses.
It proved to be much easier than we have thought.
Step Ⅴ Consolidating and Applying the rule
Exercise to be shown on the PPT and one student at a time to do the exercise orally.
(Judging whether the sentences contain predicatives, using sentence pattern “S+V+P” to rewrite sentences, correspondent practices in workbooks.
Step Ⅵ Summary and Assignment
1.Make a summary of today’s task.
2.Assign Ss to surf the write a short article to introduce an object or an
experience, using as many predicatives as possible in the article.

Australia. Thus lead to today’s topic.
StepⅡ Listening
1.Pre-listening (Ask Ss to turn to page 26 and to predict what Wei Ping might be
nervous about.)
2.Listening task(Exercise 2--- answer the questions)
3.Listening task(Exercise 3 – filling the blanks)
4.Listening again and having a discussion
Keys to tasks 2
1. He is worried about snakes.
2. No. Because he does not believe they are likely to see any and he knows what
precautions to take against being bitten.
3. He probably has talked him around because he assured Wei Ping that there was very
little danger. Also the fact that Wei Ping summarized the advice Bob gave him suggests that he has accepted bob’s assurances.
Keys to task2
snake boots and long trousers a noise do not move avoid walking
Keys to task 3
1.Because Wei Ping may think the bush means wild and dangerous land, but
Australians use it to mean the countryside where there aren’t any houses or farms or other signs of humans.
2.Because snakes don’t have legs (this is where the humor lies)
Step Ⅲ Extensive Reading
1.Pre-reading ( Ask Ss just read the title and look at the picture to predict what they
expect to read in the text)
2.Ask Ss to read the whole text and check whether what their predictions are right and
tell the main idea of the text
3.Ask Ss to read the whole text for specific information, that is, to answer questions
listed in Exercise 2.
Keys of Exercise 2:
1. 115 different kinds of snakes and 2,000 different kinds of spiders. Only a few kinds of
spiders and snakes are capable of killing humans.
2. Most jellyfish can cause severe pain to anyone who touches them but only the box
jellyfish can kill a human
3. It was cheaper to hire a car with other people because they could share the cost. Also
he probably enjoyed being in the company of other tourists.
4. The saltwater crocodile.

Supplement materials of debate
Introduction
A debate round has two teams with two debaters each and a Speaker. The Speaker serves as both the judge and arbiter of the rules during the round. Note here that "Speaker" always refers to the judge from this point forward. One team represents the Government, while the other represents the Opposition. The Government team is composed of a Prime Minister, who speaks twice, and a Member of Government, who speaks once. The Opposition team is composed of a Leader of the Opposition, who speaks twice, and a Member of the Opposition, who speaks once. The Government proposes a specific case statement, which the government team must demonstrate to be correct. The Opposition does not have to propose anything, but must demonstrate that the case statement is not correct. The Speaker decides at the end of the round, based on the arguments made in the round, whether the Government has proved its case or whether the Opposition has disproved it. The team which met its burden more convincingly wins.
Rules of Debate Rules of Debate
(condensed from Competitive Debate: Rules and Techniques,
by George McCoy Musgrave. New York: H.W. Wilson, 1957)
1. There are two teams, each consisting of two or three speakers.
2. Each team has two or three constructive speeches, and two to three rebuttal speeches. The affirmative gives the first constructive speech, and the rebuttals alternate: negative, affirmative, negative, affirmative. The affirmative has both the first and last speeches of the debate.
3. When worded as a proposition of policy, the topic requires the affirmative to
support some specified action by some particular individual or group. The affirmative has the right to make any reasonable definition of each of the terms of the proposition. If the negative challenges the reasonableness of a definition by the affirmative, the judge must accept the definition of the team that shows better grounds for its interpretation of the term.
4. The affirmative must advocate everything required by the topic itself. No revision of position of a team is permitted during the debate.
5. He who asserts must prove. In order to establish an assertion, the team must support it with enough evidence and logic to convince an intelligent but previously uninformed person that it is more reasonable to believe the assertion than to disbelieve it. Facts must be accurate. Visual materials are permissible, and once introduced, they become available for the opponents' use if desired.
6. In the questioning period, the questioner may ask any fair, clear question that has a direct bearing on the debate. The questioner may use the period to build up any part of his own case, to tear down any part of his opposition's case, or to ascertain facts, such as the opposition's position on a certain issue, that can be used later in the debate. The questioner must confine himself to questions and not make statements, comments, or ask rhetorical questions.
7. Each speaker is questioned as soon as he concludes his constructive speech. The witness must answer the questions without consulting his colleagues.
8. No new constructive arguments may be introduced in the rebuttal period. The affirmative must, if possible, reply to the major negative arguments before the last rebuttal.
9. The judge must base his decision entirely on the material presented, without regard for other material which he may happen to possess.
10. Any gains made outside of the established procedure are disallowed.

Unit 2 King Lear 教学内容分析 本单元的中心话题是“莎士比亚与他的戏剧《李尔王》。语言技能和语言知识都是根据这一中心话题设计的。 Warming Up 部分由两组问题组成，第一组问题以“子女对父母的尊敬和爱戴”这一话题为中心，要求学生联系自身实际谈一谈如果尊重和爱戴父母，引起学生对这一话题的重视和深层思考。第二组问题是关于我国古代君臣关系和皇室混一等话题，要求学生谈谈中国古代帝王如果对待自己的子女和臣仆。这两个问题都与阅读课文《李尔王》密切相关，“热身”部分的讨论可以帮组学生更好的理解居中任务之间的关系及剧情的发展。 Pre-reading部分简要介绍了关于课文的一些基本情况（如作者---William Shakespeare; 剧名—King Lear; 特点—shortened, simplified, modernized 以及主要出场人物---main characters等）。由于莎翁戏剧往往情节生动而曲折，内容丰富有深刻的教育意义，因此教师可以鼓励学生在“热身”讨论的基础上，结合练习提示的单词，根据课文插图等线索大胆预测故事内容。允许学生编出与课文内容完全不同的内容，只要情节合理，有现实意义，都应当给予肯定。学生也在编故事和讲故事的过程中哦你更体会到学习的乐趣。 Reading部分取自莎士比亚四大悲剧之一---《李尔王》。该剧首演于1606年。统治英国的李尔王想把国土分给三个女儿。他试探三个女儿的孝心，大女和次女极尽阿谀奉承之词骗得了李尔王的信任，各得到二分之一的领土。而又女阴直言不讳而惹怒父亲，一无所有，幸被法兰西国王娶为皇后。李尔退位后遭到两个女儿的冷眼和遗弃，她们甚至密谋要除掉他。幸亏忠臣相救，李尔才幸免于难。后来小女儿挂帅领兵为父复国。这时，另两个女儿之间已出现矛盾，她们尔虞我诈要除去对方，但面对法军，她们又联合起来。此战英军获胜，两个女儿囚禁了李尔与其小女儿，但却招来朝野上下一直不满。结果李尔的小女儿被害死，两个大女儿也没有得到好下场，最后李尔抱住小女儿的尸体痛哭，自己也伤心而死。“阅读”部分节取该剧的第一幕，其中李尔王与女儿的对白堪称莎翁作品中最为经典的篇章之一。 Comprehending部分的三个练习都是帮助学生更好的理解课文的内容，对理解层次的要求也是逐步加深。练习 1 要求学生根据课文回答问题，这些问题都是事实性问题，学生很容易从文中找到答案。练习2在难度上有所提高，要求学生分析剧中人物之间的关系以及各个人物的性格特点，这既要求学生找到课文中与此相关的文字，也要求学生从课文中人物的言行举止的描述判断出他们的性格特点。练习3的开饭度和难度最高，这个练习设计的是面对面的访谈形式，旨在帮助学生从居中跳到剧外，从而以更加理性的思维来体会剧中人物的内心活动。这类练习没有唯一答案，仁者见仁，智者见智，学生可以根据自己的理解给出不同的答案，而要想给出合情合理的回答，学生必须深入而细致地分析人物的每一句的字面含义和真实含义。 Learning about Language 部分突出了本单元的一些重点词汇和语法。词汇部分练习1考察学生在新的语境中运用短语的能力。练习2 和练习3着重练习的焦点是复合式形容词。这类词在本课中出现较多，在这里做了一个比较全面的归纳。练习4开篇就告诉学生活用同义词以避免重复，使学生明白：学习同义词的目的不单纯是为了扩大词汇量，如果能善用同义词，则可使上下文在形式上避免过于单调，而同时在意义上得以相互辉映。语法部分的练习1是语篇题，联系要求学生辨认短文中的状语。短语简要介绍了莎士比亚的生平，对课文的内容害死一个有益的补充。这个练习考察的是学生对状语形式的辨认，属于低层次的要求。

2012高二英语教学设计Unit 4 Sharing：Period1Warming Up and Listening （新人教版选修7） 设计者周萍 教材分析 本单元的话题是Sharing，主要涉及帮助弱者、志愿服务、合作分享等。通过听、说、读、写等各种活动学习相关的语言知识，使学生了解世界上很多地方依然很落后，从而懂得同情，学会分享。了解一些志愿者工作的信息，培养学生互助合作的精神和社会责任感。结合针对短文话题的探讨激发学生的国际意识，通过各种渠道力所能及地为贫困地区的孩子作出自己的贡献。 Warming Up部分是一个调查，分成三项任务：首先回顾自己曾经做过的助人为乐的好事，并采访三位同学；然后，根据调查内容列举班级同学所做的好事；最后讨论volunteer 的内涵。通过这些任务，让学生懂得什么是“帮助”，反思自己是否乐于助人，以及怎样做才是“志愿者”，由此为后面的短文学习做好铺垫。 Pre－reading是Reading的热身活动。交代了阅读文章的文体(letter)和作者(a young Australian woman，Jo)，还根据她在PNG拍的10张照片提出了5个问题，回答这些问题有助于学生加深理解“志愿者活动”的意义。 Reading是一篇Jo写给Rosemary的信。其中介绍Jo在PNG(Papua New Guinea)的一个小山村教书。在她写给Rosemary的信中，作者描述了该村学校的情况和去一个学生家做客的经历，使学生感受到PNG的儿童生活处境的艰难，更加珍惜自己的学习机会。 Comprehending是根据短文设计的阅读理解试题。第一个练习要求学生读懂书信的内容，用表格的形式帮助学生整理书信中提到的关于巴布亚新几内亚村落生活及风俗习惯的信息，属于细节题。第二个练习要求学生对文中提到的五个现象进行分析，说明原因，属于细节推理题。第三个练习要求学生通过阅读分析生活在小山村中的积极面和消极面，这个练习进一步地开阔学生的思维，使学生对艰苦的生活有更深的理解。第四个练习要求学生小组活动，讨论四个问题，进一步巩固学生对于课文内容的理解，并且让学生联系自己的实际情况，通过比较校舍、教学条件、生活状况等方面的问题，引发学生的深层思考，谈谈自己是否愿意参加志愿者活动。第三、四两个练习都属于深层思考的问题。 Learning about Language分词汇和语法两部分。其中，第一部分是有关此篇短文中的重点单词和短语。设置了三个练习，一是根据所给解释从所学词汇中选择相应的单词；二是用恰当的词汇完成一篇短文；三是根据解释组成词组，并用词组编对话。第二部分是有关限制性定语从句的复习。首先从课文中找出含有限制性定语从句的句子；然后用定语从句完成句子，对定语从句加以运用；再用含有定语从句的句子回答问题；最后是两人结对活动，进一步练习使用定语从句。 Using Language是对Reading的延伸。通过阅读，参与“Give an unusual gift”的活动。这个部分由三个部分组成，综合训练学生听说读写四个方面的能力。“读与说”通过图文结合的方式，介绍了一些特殊的礼品——为穷人和真正需要它们的人选购礼品。阅读之后，完成两个练习：回答问题和把礼物名称和详细介绍配对。“听与说”部分是采访默里大夫的经历，以听力训练为核心设置了四个活动。1.讲述一个人的生平，用到了时间表达法；2.通过列表

人教版选修10课文译文 一次成功的失败经历 如果起初不成功，就要一次又一次地尝试。——W·C·菲尔兹 1914 年 8 月，珀斯·布莱克鲍罗参加了欧内斯特·沙克尔顿爵士的“持久号”轮船南极探险。沙克尔顿是他那个时代最负盛名的探险家，加入他的探险活动被认为是一种巨大的荣耀。现在请看读帕斯所讲故事的第一部分。 1916 年 8 月 29 日慢慢地，我把头探出睡袋，向四周看了看。一切都是灰色的：小屋里面看上去是灰色的，晨曦看上去是灰色的，燃油炉上噗噗作响的罐子也是灰色的。同往常一样，气味中混合着汗液、海豹油脂和脏内衣的味道，几乎让人难以忍受。我尝试着想一些快乐的事情：温暖和干爽的衣服、舒适的卧室、阳光灿烂的日子、妈妈的脸庞，以及返家后得到的庆贺，因为我是试图横穿南极大陆的一次失败探险活动的成员之一，这种事以前还没有人做过。正想到这儿，一条黑毛毯掉下来把我盖住，几乎把美好时光的记忆封闭住了。 一想到由于冻伤变黑而必须截去的腐烂的脚趾头，我就感到喘不过气来。我们的境况让人绝望，谁也不清楚会不会活着回去。也许好些年后，我们的尸体会被其他探险队所辨认并搜集起来。 正当我快要变得自我怜惜起来时，我们营棚的门开了，一股冷空气穿过营棚。“把门关上!”我用一种自己都快辨认不出来的沙哑的嗓音嚷嚷道。“坚持下去，珀斯。不要变成另一个汤姆。”一个声音在应答。“我们又逮住了一只企鹅，今晚有企鹅汤喝了!”保佑弗兰克一吓尔德，他可是我们的头儿欧内斯特·沙克尔顿之外最好的人啦。我怎么能像汤姆·奥德·利兹那样自私自利和脾气暴躁呢!我挣扎着下床，新的一天开始了。 当初宣布探险活动时，我才 20 岁，老梦想着要去冒险。所以在 1914 年 7 月的一个早晨，我是怀着无比激动的心情读以下这则广告的： 为危险之旅招募人手：工资低廉、寒冷无比、数月不见天日、无法确保安全返回。如果成功，荣耀和报酬将会接踵而至。欧内斯特·沙克尔顿爵士。 同伟大的欧内斯特·沙克尔顿爵士去南极探险——我被深深地迷住了!我是探险的门外汉，但我年轻，身体健康而且精力充沛。我偷偷地上了“持久号”轮船，藏在一个小橱里。直到轮船已开始航行了，我才被人发现，而且晕船晕得很厉害。不管怎么说，沙克尔顿似乎对我傻乎乎的行为感兴趣，并且接受了这种局面。他让我当一名伙计，协助做 28 个人一天三顿的饭菜。 1915 年 1 月 18 日，正当我们接近南极时，“持久号”被海上的浮冰(有的坚固无比，有的破裂成若干巨大的冰块浮在水上)卡住了。周围的冰都冻结了，我们千真万确地被困住了!轮船在我们的眼前慢慢地被挤坏。我相信沙克尔顿肯定会对这次探险意想不到的结局而痛心，但他并没有把时间浪费在遗憾和悔恨中。他镇静地把大家召集在一起，然后紧急宣布我们必须在船沉下去之前，只抢出基本给养，尤其是小船、食物、炊具、蜡烛、卧具和衣服。为了显示自己的决心，沙克尔顿把一些金币和他的金表扔到冰上。然而，让我感到惊讶的是，他竟鼓励赫西带上班卓琴。他把班卓琴描述成让我们保持精神振奋的关键。 他的顽强精神赢得了我们对他的完全信赖。他对我们也总是坦诚相待(就像广告中那样)，他从不灰心丧气，从不放弃，甚至当轮船沉下去时也是如此。1916 年 4 月 9 日，我们搬到了大象岛上现在的宿营地。不久沙克尔顿给我们这里的生活列出了规矩：取消级别和社会地位上的差异，每个人都得忙起来；公平分配食物和卧具；关心每一个人。这种团队精神鼓舞了船员们的士气，并挽救了我们的生命。 我们在大象岛上一安顿好，沙克尔顿就马上向大家解释了他的营救计划：22 人留在这里，他挑选其他五个人去南乔治亚求援。由于谁也不知道我们身处何地，所以不能指望任何外部救援。我永远也不会忘记眼看着小船从哗哗作响的波浪中消失在波涛汹涌的大洋里的情景。留在大象岛上的人发誓要按他所主张的那样做：在他返回来救我们之前要保持乐观、恢复健康。
