Advice on Public Speaking Building confidence ( 信心)Faith in yourself, your topic and your healthy mind is a must if you are to be a better publicspeaker. Many speakers are not prepared and lose confidence because of that. But others lack confidencebecause they are afraid of being judged--and possibly made fun of--just like they were in high schoolspeech class. Build your confidence by using all your tools and knowing that you are excellent.Knowing what&39;s upYou have to know your topic inside and out. Nothing kills your speech like um and uh in every sentence. Research your subject to the point where you are an expert. And that&39;s half the battle.PracticingResearching and knowing your topic is one thing, but actually delivering that information isanother. Practicing your speech in advance is a must. You will find your beats and your direction,through hours in front of the mirror practicing. So when you climb up on stage, it will be like riding ahike,unless you don&39;t know how to ride a bike.Dressing properlyYou will want to dress properly for the occasion(场合)--which could be a suit or simply ajacket. Make sure it also has the comfort you need. If the clothes are not comfortable, you may notpay full attention to your speech.Making connectionsMake a personal connection with someone in the audience (听众). It might be someone youknow that you can call out to, or someone in the front row you can speak directly to. Maybe yourspeech leads you to ask them a question, which is an easy way for you to take yourself from the stageand place yourself as one of your audience. It also takes the pressure off. What does that’s half the battle mean in the text?A.You have already won the battleB.You are getting on the way to final successC.You need experts to guide you in public speakingD.You should write sentences without um and uhThe author compares delivering a speech to riding a bike because both of them needA.guidingB.practiceC.proper dressingD.self-confidenceWhich of the following ways is suggested in making connections with the audience?A.Looking at someone in the distanceB.Calling out to someone you don’t knowC.Asking someone in the audience a questionD.Shaking hands with someone in the front rowWhat is the main purpose of the text?A.To show you how to dress properlyB.To help you become a good speakerC.To teach you how to gain confidenceD.To help you get to know the audience请帮忙给出每个问题的正确答案和分析,谢谢!
