An effective topic sentence—
- clearly supports the thesis statement.
- is usually at the beginning of a body paragraph (1st or second sentence).
- controls the content of all of the supporting sentences in its paragraph.
- is a complete sentence.
- does not announce the topic (e.g., “I’m going to talk about exercise.”)
- should not be too general (e.g., “Exercise is good.”).
- should not be too specific (e.g., “Exercise decreases the chance of developing
diabetes, heart disease, asthma, osteoporosis, depression, and anxiety.”).
