 I think that covers most of the things that we want to say about how to give effective oral presentation. In our presentation, we focus three main areas, training your presentation, organizing your presentation, and delivering your presentation to conclude. I would like to sum up the points we've made in a way that I hope you will find easy to remember, and these are the key points that you need to consider during the presentation process. These are the principles of the presentation. Purpose. What is the objective of your presentation? People. Who will you be talking to? Preparation. What kinds of information and ideas will you include? Planning. How will you plan your material? And finally, performance. How can you communicate your ideas effectively? These are the principles of presentation. These are the principles that each and every one of you will need to consider if you want to give effective oral presentation here at PolyU. Thank you. That's the end of our presentation. You can see our full reference list on our final slide, and now we will be very happy to answer any question you have. Are there any questions?
