Above all know your audience and match what you say to their needs．Creating your presentation with your audience in mind will assure that your audience will follow you．If your presentation doesn't appeal to your audience-no matter how well you have developed your presentation--your presentation will fall on deaf ears．This leads us to the next rule:Know your material thoroughly．Your material needs to be second nature to you．Practice and rehearse your presentation with friends,in front of a mirror,and with colleagues．If you are speaking in a second language,make sure that you record yourself and listen to a number of times before going to practice with a native speaker(if possible). Remember that you are an actor when presenting．Make sure that not only your physical appearance is appropriate to the occasion,but also the tone you use is well chosen．If your topic is serious,be solemn．However,it's always a good idea to begin your presentation with an ice-breaker．Don't worry about making friends,rather lead the audience through your materials in a calm and relaxed manner．Speak slowly and clearly,and remember to address everyone in the audience-even the person the farthest away from you. To achieve the above goals follow these tips when giving your presentation: ●Speak with conviction．Believe what you are saying and you will persuade your audience． ●Do not read from notes．Referring to notes is fine,but do so only briefly. ●Maintain eye contact with your audience．Making direct eye contact with individuals will help them feel as if they are participating in your presentation. ●Bring handouts．Don't just use a PowerPoint presentation．Provide audience members with handouts of the most important materials so they can keep your most important takeaways in mind. ●Know when to stop．This cannot be underestimated．You need to make your case,but continuing for too long will only ensure that the audience forgets what you have said. Why should you know when to stop?
A、Because you need res
B、Because audience may fall aslee
C、Because you may be tired for talking too lon
D、Because it can make audience remember what you sai
【正确答案】：D
【题目解析】：在这段文本中，作者强调了在进行演讲或展示时需要注意的多个方面，包括了解观众、熟悉材料、注意个人表现、演讲技巧等。其中，在“To achieve the above goals follow these tips when giving your presentation:”部分，作者给出了一系列实用的建议。 对于问题“Why should you know when to stop?”，我们可以从提供的建议中找到答案。在“Know when to stop”这一建议中，作者指出：“This cannot be underestimated. You need to make your case, but continuing for too long will only ensure that the audience forgets what you have said.” 这句话明确指出，尽管你需要充分表达自己的观点，但演讲时间过长只会让观众忘记你之前所说的内容。 接下来，我们逐项分析选项： A. Because you need res（因为你需要休息） - 文中并未提及演讲者需要休息作为停止演讲的原因。 B. Because audience may fall asleep（因为观众可能会睡着） - 文中没有提到观众会因此睡着。 C. Because you may be tired for talking too long（因为你可能会因为说得太久而疲倦） - 同样，文中没有提到演讲者会因疲倦而需要停止。 D. Because it can make audience remember what you said（因为这可以让观众记住你说的话） - 这与文中的建议“continuing for too long will only ensure that the audience forgets what you have said”相呼应，即适时停止演讲有助于观众记住你所说的内容。 因此，正确答案是D：“Because it can make audience remember what you said”。
