Today let's talk about the discussion of what makes a good public speaker. There are three key aspects that you should consider: preparation, delivery and interaction.
 
Preparation
 
　　Preparation is the key. You need to make sure that you have a good topic and material under your belt.
 
　　1.Choose a good topic. 
 
　　I think any topic can be a good one as long as it excites you and it is relevant to the audience. If you are enthusiastic about it, your audience will enjoy it more. Excitement makes you have more animation in the delivery of your presentation and thus a more effective presentation overall. 
 
　　2. Gather supporting materials. 
 
　　Look through magazines, newspapers and the internet for relevant materials. Ask your friends or colleagues for content ideas. This will help you decide on the right angle and structure of your speech.
 
　　3. Piece together your ideas. 
 
　　Think about what will go into the introduction, body, and conclusion of your presentation. 
 
　　A good introduction is very important. Think: how can you grab the audiences' attention? A startling statement, a quotation or a statistic? 
 
　　The body of the presentation should be well structured so it is easy to follow. You will want to have a few points with supporting pieces of evidence to fit each point. Make sure the evidence you choose relates to the point being made and is a strong support so that your audience will understand or be moved to action. 
 
　　The conclusion of a speech is just as important. This is like the grand final of a concert that will bring your speech to a climax. It could be a brief summary or a call for action. I always love a good rhetorical question that sets your audiences' minds thinking. You don't have to raise your voice but a good question is all you need.
 
　　4. Practice and rehearse. 
 
　　Begin by using parts of your speech in conversation with friends and colleagues.  Does your friend seem to be influenced by the evidence? Once you have tried it out, then start to put the ideas together in a coherent manner. 
 
Delivery

　　However, good content is nowhere near the end of the matter. A great speech requires a great delivery to make it truly memorable and inspiring. So how can you make sure that your well prepared speech is equally well delivered? 
 
　　1. Use your eyes 
 
　　Keeping your audience alert and interested is a key factor in your delivery. Ideally you want to make each member of the audience feel as though you're talking directly to them. They all want to feel connected. If you achieve this then you will have an audience whom you can then inspire with your words. 
 
　　2. Use your voice 
 
　　Vary the tone, pitch, speed and sentence length of your speech. Speak clearly and slowly, pausing after each important point. Remember don't rush.
 
　　You can use the pitch and tone of your voice to help emphasise descriptive sections of your speech, helping you create pictures in the minds of your audience. For instance a phrase such as "the train rushing through the station" would benefit immensely if you emphasis the word 'rushing' and imitate that rushing sound in your voice. 
 
　　3. Use your body 
 
　　Effective use of body language is advisable. However don't want to overdo it. When people are nervous they can be at one of two extremes. One is rigid, robotic appearance; the other is an ultra-high energy performance. You would want to strike a nice balance between the two and make yourself as natural and comfortable as possible.  
 
　　Last but not least, don't take it too seriously. I know this sounds a bit illogical but psychologically it works better that way, because you are less nervous and more confident.
 
　　Good luck and remember practise makes perfect.
