MODULE 5 A Trip Along the Three GorgesPart One: Teaching DesignPeriod One: Reading—A Trip Along the Three GorgesGoalsTo learn to read passages about the Three GorgesTo learn to read with strategiesProcedures▇Warming up by defining gorgeA canyon, or gorge, is a valley walled by cliffs. Most canyons originate by a process of long-time erosion from a plateau level, with a stream gradually carving out its valley. The cliffs form because harder rock strata that are resistant to erosion and weathering remain exposed on the valley walls. Canyons are much more common in arid areas than in wetter areas because weathering has a lesser effect in arid zones. Canyons' walls are often formed of resistant sandstones or granite. ...▇Before you readPlease go over the word list for this module, paying attention to the pronunciation of the word, the relationship between its pronunciation and its spelling.▇While you readCut/ the sentences into thought groups, blacken the predicates, underline the useful expressions▇After you read▇Closing down by drawing a diagram of the textYou are going to read the text again and draw a diagram of it.

The Three Gorges occupy approximately 120 km within this region. Although it is primarily famous for its scenery, the Three Gorges region is historically, andThe Three Gorges region is located along the Yangtze River between the cities of Fengjie (奉节) and Yichang in Chongqing municipality and Hubei province.Currently the Three Gorges region is most famous for the Three Gorges Dam. The Three Gorges Dam is under construction at a place called Sandouping (三斗坪) in the middle of the Xiling Gorge. The dam is not yet complete, but the construction has already cut off the flow of the river, and therefore the water level in the Qutang, Wuxia, and the western portion of the Xiling Gorges has already begun to rise. In addition to the impacts of the dam on the ecology and people (i.e. the mass relocation of towns and villages) of the region, the dam will also change the scenery of the Three Gorges. Because the water level will be higher, the gorges will be less narrow and the mountains will appear lower. Proponents of the dam point out that because the mountains reach several thousand feet above the river, the gorges are still likely to offer spectacular views of the surrounding cliffs, and it should be noted that most riverboat companies that operate in the Three Gorges intend to continue to offer tours of the region. The increase in width of the Gorges will also allow larger ships through the gorges and it is anticipated that river traffic of all kinds will increase.▇Talking about the Three GorgesPeriod Five: Writing—Describing a regionGoalsTo gather related information and write a short description of the region you live in Procedures▇Collecting and sharing related information about the region▇Writing a short description of the region you live inPeriod Six: CULTURAL CORNER—Postcards to MyselfGoalsTo read about travelingProcedures▇Before you readPlease go over the word list for this module, paying attention to the pronunciation of the word, the relationship between its pronunciation and its spelling.▇While you readCut/ the sentences into thought groups, blacken the predicates, underline the useful expressions▇After you readCopy all the useful expressions into your Expression Book. You may make sentences with these▇Talking about Postcards to MyselfPeriod Seven: TASK—Writing rules for travelers GoalsTo learn to write rules for travelersProcedures▇Gathering information about rules for travelersPart Two: Teaching Resources for MODULE 5 A Trip Along the Three Gorges Section One: Background readings1. plateauIn geology and earth science, a plateau is an area of highland, usually consisting of relatively flat open country if the uplift was recent in geologic history.2. tourismTourism is the act of travel for the purpose of recreation, and the provision of services for this act. A tourist is someone who travels at least eighty kilometers (fifty miles) from home for the purpose of recreation, as defined by the World Tourism Organization (a United Nations body). A more comprehensive definition would be that tourism is a service industry, comprising a number of tangible and intangible components. The tangible elements include transport systems - air, rail, road, water and now, space; hospitality services - accommodation, foods and beverages, tours, souvenirs; and related services such as banking, insurance and safety and security. The intangible elements include: rest and relaxation, culture, escape, adventure, new and different experiences.Many countries depend heavily upon travel expenditures by foreigners as a source of taxation and as a source of income for the enterprises that sell (export) services to these travelers. Consequently the development of tourism is often a strategy employed either by a Non-governmental organization (NGO) or a governmental agency to promote a particular region for the purpose of increasing commerce through exporting goods and services to non-locals.Sometimes Tourism and Travel are used interchangeably. In this context travel has a similar definition to tourism, but implies a more purposeful journey.The term tourism is sometimes used pejoratively, implying a shallow interest in the societies and places that the tourist visits.3. New ZealandNew Zealand is a country of two large islands and many much smaller islands in the south-western Pacific Ocean. Among South Pacific nations, New Zealand has the largest and most industrialized economy and is second only to Papua New Guinea in population.Section Two: Words and Expressions from MODULE 5 A Trip Along the Three Gorges1. plainn. extensive tract of level open land: They emerged from the woods onto a vast open plain.adj. 1. not elaborate or elaborated;

(2)could用于疑问句,表示的语气比can更为客气、委婉;could用 于肯定句可以表示没有多大把握的推测或表示过去曾有过的能力; could还可用于虚拟语气表示与现在情况相反的假设。 *Could I stay here tonight? 今晚我可以待在这儿吗?(比can更为客气的请求) *We wish we could fly in the sky like the two birds. 我们要是能像这两只鸟儿一样在空中飞翔该多好啊。(表示对现 在事实的虚拟) (3)was/were able to与could的区别是was/were able to 表示不但有 能力,而且曾经做过某件事情。当成功地完成某件事情时,通常不用 could,而用was/were able to来表示,此时was/were able to相当于 managed to,表示“(经过一番努力)终于完成某事”。 *The older child should be able to prepare a simple meal. 这个大点儿的孩子应该能做顿简单的饭菜。
4.need与dare。 (1)need可以作情态动词使用,也可作行为动词使用。作为情态动 词使用时,没有人称与时态的变化,并且多用在否定句、疑问句和条 件句中,含义为“需要,必须”。 *If you need repair your car, come to me. 如果你需要修车,就来找我。 【点津】 ①need作为情态动词,一般不在肯定句中使用。在肯 定句中通常用must, have to, ought to, should等。 —Need I tell Mr.Li about it? ——我是否需要把这件事情告诉李先生? —No,you needn't.(Yes, you must.) ——不,没有必要。(是的,你必须。) ②“Need I...?”与“Must I...?”在意义上差别不大,因此 回答也是一样的,肯定回答为must,否定回答用needn't。
(2)dare作为情态动词时,意为“敢于,敢做„„”,多用在否定 句、疑问句或条件状语从句中。 *Dare she risk staying where she was? 她敢冒险待在原地不动吗? *The little girl dare not answer questions in class. 这个小姑娘在课堂上不敢回答问题。 (3)dare和need都可以用作实义动词,有时态、人称和数的变化。 *You didn't need to tell him the news, it just made him sad. 你无需告诉他这一消息,那只会使他伤心。 【点津】 need作实义动词使用时,宾语可以是动名词或不定 式,动名词要用主动形式,而不定式一定要用被动形式。 Does this shirt need washing?(=Does this shirt need to be washed?)这件衬衣需要洗吗?
【点津】 must所构成的疑问句,其回答的否定形式通常为 needn't或don't have to,意为“不必要”,“不用”,而一般不用 mustn't。 —Must I hand the paper in before five? ——我必须在五点钟以前把论文交上去吗? —Yes,you must.(No,you needn't.) ——是的,必须交。(不,用不着。)
3.must与have to。 must强调个人的意志和主观的决心,意为“一定,必须”;have to侧重于客观上的必须,强调客观条件作用的结果,意为“务必,不 得不”。如果用于过去时或将来时,要用have to来代替,但must可用 于间接引语,表示过去的必要和义务。 *I must shut the door, or the rain will come in. 我必须把门关上,不然雨就进来了。(强调主观意志) *I have to stop the car and wait for the policeman. 我不得不停车等警察。(表示客观使然) *You have to keep after your son if he refuses to be housebroken. 如果你儿子不服管教的话,你必须整天跟在他法精讲
Ⅰ.基础点拨 1. 情态动词的基本用法:can,could与be able to。 (1)can表示能力,其疑问形式表示请求,其否定形式常表示推 测。can只有现在时和过去时两种时态形式,其他时态只能用be able to进行表达。 *Can I have a look at your new pen? 我可以看一看你的新钢笔吗?(此处can用在疑问句中表示“请 求”) *When I left school at 16, I couldn't read or write. 我16岁离开学校时不会读也不会写。(表示“能力”)*Have you been able to have any kind of contact? 你取得任何联系了吗?(完成时态用be able to来表示)
2.may与might。 (1)may用于陈述句表示“可以”,“允许”的意思,还可以表示 “可能”;may用于疑问句表示“请求”,用于否定句表示说话人 “不允许”,“不许可”。 *You may go out for a walk. 你可以出去散散步。(表示“允许”) *You may not speak loudly. 不允许高声说话。(否定形式表示“不允许”)
【点津】 may引导的疑问句,肯定回答用“Yes, you may.”;否 定回答用“No,you mustn't./No,you can't./No,you had better not.”,表示“千万不要”,“不可以”,“禁止”之意。 May I come in?我可以进来吗? Yes,please.(No,you mustn't.)请进。(不,不行。) (2)might (could)用于一般现在时,表示更为委婉和礼貌的语气。 *Might I use your pen? 我可以用你的钢笔吗?
