议Presentation在大学英语口语教学中的应用
议Presentation在大学英语口语教学中的应用摘要：本文介绍了Presentation教学法的内容，优势及其操作程序，并通过这一方法在高校英语口语课堂中的实践证明，它对学生综合素质的提高有一定的积极作用。
关键词：展示英语口语课堂综合语言能力1 引言Presentation在中文中即演出、呈现的意思。
在现今的西方国家中，presentation 作为一种交流方式，即在一群人面前公开演讲，演讲的主题通常是项目的内容或任务的完成情况。
它在人们的日常工作和生活中都非常流行，如产品展示、学术交流等。
在本文语境中，presentation(口头展示)指课堂上学生个人或小组向全班讲解某一话题的一种教学实践活动。
它是西方课堂教学中普遍使用的一种教学手段。
而这项对于西方学生来说轻车熟路的教学活动令刚接触到它的中国学生，轻则无所适从，重则望而生畏。
然而经历了最初的困惑、窘迫，如今这种新型的教学活动已被广泛应用在各个学科领域之中，并且从中受益匪浅。

presentation 讲义1
IntroductionAll presentations have a common objective. People give presentations because they want to communicate in order to:∙inform∙train∙persuade∙sellA successful presentation is one of the most effective ways of communicating your message. And because English is so widely used in international business, a working knowledge of the vocabulary and techniques used in an English language presentation is a valuable asset.PreparationCan you name the 3 most important things when giving any presentation?Number 1 is . . .PreparationNumber 2 is . . .Preparation!Number 3 is . . .Preparation!!Preparation is everything!With good preparation and planning you will be totally confident and less nervous. And your audience will feel your confidence. Your audience, too, will be confident. They will be confident in you. And this will give you control. Control of your audience and of your presentation. With control, you will be 'in charge' and your audience will listen positively to your message. ObjectiveBefore you start to prepare a presentation, you should ask yourself: "Why am I making this presentation?" Do you need to inform, to persuade, to train or to sell? Your objective should be clear in your mind. If it is not clear in your mind, it cannot possibly be clear to your audience. Audience"Who am I making this presentation to?" Sometimes this will be obvious, but not always. You should try to inform yourself. How many people? Who are they? Business people? Professionalpeople? Political people? Experts or non-experts? Will it be a small, intimate group of 4 colleagues or a large gathering of 400 competitors? How much do they know already and what will they expect from you?Venue"Where am I making this presentation?" In a small hotel meeting-room or a large conference hall? What facilities and equipment are available? What are the seating arrangements?Time and length"When am I making this presentation and how long will it be?" Will it be 5 minutes or 1 hour? Just before lunch, when your audience will be hungry, or just after lunch, when your audience will be sleepy?MethodHow should I make this presentation?" What approach should you use? Formal or informal? Lots of visual aids or only a few? Will you include some anecdotes and humour for variety?Content"What should I say?" Now you must decide exactly what you want to say. First, you should brainstorm your ideas. You will no doubt discover many ideas that you want to include in your presentation. But you must be selective. You should include only information that is relevant to your audience and your objective. You should exclude all other ideas. You also need to create a title for your presentation (if you have not already been given a title). The title will help you to focus on the subject. And you will prepare your visual aids, if you have decided to use them. But remember, in general, less is better than more (a little is better than a lot). You can always give additional information during the questions after the presentation.StructureA well organised presentation with a clear structure is easier for the audience to follow. It is therefore more effective. You should organise the points you wish to make in a logical order. Most presentations are organised in three parts, followed by questions:NotesWhen you give your presentation, you should be - or appear to be - as spontaneous as possible. You should not read your presentation! You should be so familiar with your subject and with the information that you want to deliver that you do not need to read a text. Reading a text is boring! Reading a text will make your audience go to sleep! So if you don't have a text to read, how can you remember to say everything you need to say? With notes. You can create your own system of notes. Some people make notes on small, A6 cards. Some people write down just the title of each section of their talk. Some people write down keywords to remind them. The notes will give you confidence, but because you will have prepared your presentation fully, you may not even need them!RehearsalRehearsal is a vital part of preparation. You should leave time to practise your presentation two or three times. This will have the following benefits:∙you will become more familiar with what you want to say∙you will identify weaknesses in your presentation∙you will be able to practise difficult pronunciations∙you will be able to check the time that your presentation takes and make any necessary modificationsSo prepare, prepare, prepare! Prepare everything: words, visual aids, timing, equipment. Rehearse your presentation several times and time it. Is it the right length? Are you completely familiar with all your illustrations? Are they in the right order? Do you know who the audience is? How many people? How will you answer difficult questions? Do you know the room? Are you confident about the equipment? When you have answered all these questions, you will be a confident, enthusiastic presenter ready to communicate the subject of your presentation to an eager audience.EquipmentEasily your most important piece of equipment is...YOU! Make sure you're in full working order, and check your personal presentation carefully - ifyou don't, your audience will!The overhead projector (OHP) displays overheadtransparencies (OHTs or OHPTs). It has several advantages overthe 35mm slide projector:∙it can be used in daylight∙the user can face the audience∙the user can write or draw directly on the transparencywhile in useThe whiteboard (more rarely blackboard or greenboard) is a useful devicefor spontaneous writing - as in brainstorming, for example. For preparedmaterial, the OHP might be more suitable.The duster is used for cleaning the whiteboard. It is essential that the duster beclean to start with. You may consider carrying your own duster just in case.Markers are used for writing on the whiteboard (delible - you can remove theink) or flipchart (indelible - you cannot remove the ink). They are usuallyavailable in blue, red, black and green. Again, it's a good idea to carry a spare set of markers in case you are given some used ones which do not write well."A good workman never blames his tools."The flipchart consists of several leaves of paper that you 'flip' or turn over. Somepeople prefer the flipchart to the whiteboard, but its use is limited to smallerpresentations.The Slide projector - which must be used in a darkenedroom - adds a certain drama. Some slide projectors can besynchronised with audio for audio-visual (AV)presentations. These projectors are typically used forlarger presentations. The majority take 35mm slides ortransparencies (as seen here), but projectors for 6x6cm slides are also available.Transparencies are projected by an overhead projector or a slide projector onto ascreen - in this case a folding screen which can be packed up and transported.The notebook computer is increasingly being used to display graphics duringpresentations. It is often used in conjunction with an overhead projector, whichactually projects the image from the computer screen onto the wall screen.Handouts are any documents or samples that you 'hand out' or distribute to youraudience. Note that it is not usually a good idea to distribute handouts before yourpresentation. The audience will read the handouts instead of listening to you.Delivery'Delivery' refers to the way in which you actually deliver or perform or give your presentation. Delivery is a vital aspect of all presentations. Delivery is at least as important as content, especially in a multi-cultural context.NervesMost speakers are a little nervous at the beginning of a presentation. So it is normal if you are nervous. The answer is to pay special attention to the beginning of your presentation. First impressions count. This is the time when you establish a rapport with your audience. During this time, try to speak slowly and calmly. You should perhaps learn your introduction by heart. After a few moments, you will relax and gain confidence.Audience RapportYou need to build a warm and friendly relationship with your audience. Enthusiasm is contagious.If you are enthusiastic your audience will be enthusiastic too. And be careful to establish eye contact with each member of your audience. Each person should feel that you are speaking directly to him or her. This means that you must look at each person in turn - in as natural a way as possible. This will also give you the opportunity to detect signs of boredom, disinterest or even disagreement, allowing you to modify your presentation as appropriate.Your objective is to communicate!Body LanguageWhat you do not say is at least as important as what you do say. Your body is speaking to your audience even before you open your mouth. Your clothes, your walk, your glasses, your haircut, your expression - it is from these that your audience forms its first impression as you enter the room. Generally speaking, it is better to stand rather than sit when making a presentation. Be aware of and avoid any repetitive and irritating gestures. Be aware, too, that the movement of your body is one of your methods of control. When you move to or from the whiteboard, for example, you can move fast or slowly, raising or reducing the dynamism within the audience. You can stand very still while talking or you can stroll from side to side. What effect do you think these two different approaches would have on an audience?Cultural ConsiderationsBecause English is so widely used around the world, it is quite possible that many members of your audience will not be native English-speakers. In other words, they will not have an Anglo-Saxon culture. Even within the Anglo-Saxon world, there are many differences in culture. If we hypothetically imagine a German working for an Israeli company making a presentation in English to a Japanese audience in Korea, we can see that there are even more possibilities for cultural misunderstanding. You should try to learn about any particular cultural matters that may affect youraudience. This is one reason why preparation for your presentation is so important. Cultural differences can also be seen in body language, which we have just discussed. To a Latin from Southern France or Italy, a presenter who uses his hands and arms when speaking may seem dynamic and friendly. To an Englishman, the same presenter may seem unsure of his words and lacking in self-confidence.Voice qualityIt is, of course, important that your audience be able to hear you clearly throughout your presentation. Remember that if you turn away from your audience, for example towards the whiteboard, you need to speak a little more loudly. In general, you should try to vary your voice. Your voice will then be more interesting for your audience. You can vary your voice in at least three ways:∙speed: you can speak at normal speed, you can speak faster, you can speak more slowly - and you can stop completely! You can pause. This is a very good technique for gaining your audience's attention.∙intonation: you can change the pitch of your voice. You can speak in a high tone. You can speak in a low tone.∙volume: you can speak at normal volume, you can speak loudly and you can speak quietly.Lowering your voice and speaking quietly can again attract your audience's interest.The important point is not to speak in the same, flat, monotonous voice throughout your presentation - this is the voice that hypnotists use to put their patients' into trance!Visual aidsOf all the information that enters our brains, the vast majority of it enters through the eyes. 80% of what your audience learn during your presentation is learned visually (what they see) and only 20% is learned aurally (what they hear). The significance of this is obvious:∙visual aids are an extremely effective means of communication∙non-native English speakers need not worry so much about spoken English - they can rely more heavily on visual aidsIt is well worth spending time in the creation of good visual aids. But it is equally important not to overload your audience's brains. Keep the information on each visual aid to a minimum - and give your audience time to look at and absorb this information. Remember, your audience have never seen these visual aids before. They need time to study and to understand them. Without understanding there is no communication.Apart from photographs and drawings, some of the most useful visual aids are charts and graphs, like the 3-dimensional ones shown here:Piecharts are circular in shape (like a pie).Barcharts can be vertical (as here) or horizontal.Graphs can rise and fall.Audience ReactionRemain calm and polite if you receive difficult or even hostile questions during your presentation. If you receive particularly awkward questions, you might suggest that the questioners ask their questions after your presentation.LanguageSay what you are going to say,Simplicity and ClarityIf you want your audience to understand your message, your language must be simple and clear. Use short words and short sentences.Do not use jargon, unless you are certain that your audience understands it.In general, talk about concrete facts rather than abstract ideas.Use active verbs instead of passive verbs. Active verbs are much easier to understand. They are much more powerful. Consider these two sentences, which say the same thing:1.Toyota sold two million cars last year.2.Two million cars were sold by Toyota last year.Which is easier to understand? Which is more immediate? Which is more powerful? N°1 is active and N°2 is passive.SignpostingWhen you drive on the roads, you know where you are on those roads. Each road has a name or number. Each town has a name. And each house has a number. If you are at house N° 100, you can go back to N° 50 or forward to N° 150. You can look at the signposts for directions. And you can look at your atlas for the structure of the roads in detail. In other words, it is easy to navigate the roads. You cannot get lost. But when you give a presentation, how can your audience know where they are? How can they know the structure of your presentation? How can they know what is coming next? They know because you tell them. Because you put up signposts for them, at the beginning and all along the route. This technique is called 'signposting' (or 'signalling').During your introduction, you should tell your audience what the structure of your presentation will be. You might say something like this:"I'll start by describing the current position in Europe. Then I'll move on to some of the achievements we've made in Asia. After that I'll consider the opportunities we see for further expansion in Africa. Lastly, I'll quickly recap before concluding with some recommendations."A member of the audience can now visualize your presentation like this:He will keep this image in his head during the presentation. He may even write it down. And throughout your presentation, you will put up signposts telling him which point you have reached and where you are going now. When you finish Europe and want to start Asia, you might say:"That's all I have to say about Europe. Let's turn now to Asia."When you have finished Africa and want to sum up, you might say:"Well, we've looked at the three continents Europe, Asia and Africa. I'd like to sum up now."And when you finish summing up and want to give your recommendations, you might say: "What does all this mean for us? Well, firstly I recommend..."The table below lists useful expressions that you can use to signpost the various parts of your presentation.。
presentation案例+答案
1.某公司接到一份经B银行保兑的不可撤销信用证。
当该公司按信用证规定办完装运手续后，向B银行提交符合信用证各项要求的单据要求付款时，B银行却声称：该公司应先要求开证行付款，如果开证行无力偿付时，则由其保证行付款。
问题：B银行的要求对不对？分析：B银行的要求是毫无道理的。
理由如下：按照《跟单信用证统一惯例》的规定，对信用证加具保兑的银行，在遵守信用证一切条款的条件下，对受益人承担付款、承兑的责任。
保兑行在信用证业务中，承担第一付款人的责任。
因此就本案例来讲，B银行为信及证的保兑行，他也就承担了首先付款的责任，对受益人提交的符合信用证要求的单据承担付款责任，而不是俟开证行无力付款时他再保证付款。
他对受益人的要求，是混淆了“保兑”和“担保付款”两种概念，他的要求是不合理的。
2.2002年2月，我国A公司与英国B公司签订出口合同，支付方式为D/P 120 days aftersight。
中国C银行将单据寄出后，直到2002年8月尚未收到款项，遂应A公司要求指示英国D代收行退单，但到D代收行回电才知道单据已凭进口商B公司承兑放单，虽经多方努力，但进口商B公司以种种理由不付款，进出口商之间交涉无果。
后中国C 银行一再强调是英国D代收行错误放单造成出口商钱货损失，要求D代收行付款，D 代收行对中国C银行的催收拒不答复。
10月25日，D代收行告知中国C银行进口商已宣布破产，并随附法院破产通知书，致使出口商钱货两空。
问题：从本案例中，我们可以吸取什么教训？分析：采用D/P远期方式，对出口方来讲存在较大风险，实际是出口商给与进口商资金融通，让进口商不必见单即付款。
所以出口商应尽量避免使用D/P远期。
如果必须要选择D/P远期，那么应把握以下几点：（1）要有风险意识，先考虑客户资信。
（2）要注意那些不做远期付款交单业务，而将其按即期或承兑交单处理的国家和地区。
（3）为避免货物运回或再处理货物的损失，可让进口商预付相关款项，如有可能预付款中可包括出口商利润。
