As long as you've researched the topic you're speaking about, writing the body of your class-assigned speech probably will be the easiest part. The introduction of a speech often is the most difficult part because it comprises the general idea of your speech, your main points and any other relevant information. Unlike the body of the speech, you have to keep your introduction short and to the point. Being concise is a necessity.
Begin with a quirky fact, famous quotation, alliteration or rhetorical question about your topic. For example, if you were speaking about your summer vacation, you could open with an alliteration, such as "Sand, salt and scorching sun" and follow with where you spent your vacation.
Explain your topic as soon as possible so the audience will know what you will be speaking about. Fully explain the topic. For example, if you're talking about the dangers of air pollution, don't just say your topic is about air pollution, explain that it's about the harmful effects of air pollution and that it's an environmental and health danger.
Inform listeners why this topic is of interest and how it can relate to them. For example, if you're speaking about the need to find alternative fuels, explain that oil will run out eventually, and everyone's lives will be significantly impacted unless alternative fuels are found.
Talk about your main points. If your speech has three main points, then you need to highlight them in the introduction. Create a verbal outline and avoid detailing your points. For example, if you are speaking about saving money, you could say, "I'm going to tell you about saving money while buying groceries, paying your utilities and saving on gasoline."
Talk about any expertise you have on the topic. Keep your background information to one or two sentences. Forgo this step if you have no expertise in the subject.
Keep the length of your introduction in line with your speech. If your total speech is three minutes long, your introduction shouldn't be two minutes. The body of your speech should always take the most time.
