presentation: the introduction, the body, and the conclusion. The function of the introduction is to greet the audience and introduce the topic. Before the presentation, you need to prepare carefully. Firstly, you should create an outline, write down the content, and practice many times. Secondly, you need to check the equipment and turn off your phone. During the presentation, you should use clear body language, make eye contact, and explain the points clearly.

Besides, you shouldn't just read from the paper or look at the floor. After the presentation, you should summarize the main ideas, thank the audience, and try to answer their questions. These steps will help you impress the audience and give an effective presentation.
