The Topic Sentence
Draw the reader into your topic with an interesting fact, observation or controversy. Depending on your format, include a graphic embedded to the left-hand corner of your introduction. This helps draw the reader's attention.
The Middle Sentences
The middle sentences of your introduction should highlight some of the specific issues you will explain in more detail later. Resist the urge to include 3 or 4 long sentences in a row. Short sentences have impact too. Try not to overload the reader with information.
Ending the Introduction
Wrap up the introduction by explaining what the reader will learn and how it will benefit them. This is where many readers decide whether it is worth their time to keep reading. Hook them with the last sentence of the introduction.
