Here's why:
* Announces the topic: The introductory paragraph introduces the main subject or idea that the entire essay or writing piece will focus on.
* States the topic: The introductory paragraph usually includes a clear and concise thesis statement, which is the main argument or point that the essay will explore and support.
Key features of an introductory paragraph:
* Hook: Starts with an attention-grabbing sentence or two (e.g., a question, surprising fact, anecdote, quote)
* Background information: Provides context to the topic, if necessary.
* Thesis statement: States the main argument or point of the essay.
Example:
"Have you ever wondered why cats are so popular as pets? Despite their reputation for independence and aloofness, felines have captured the hearts of humans for centuries. Their grace, intelligence, and playful nature make them endearing companions. This essay will explore the many reasons why cats have become such beloved pets around the world."
In this example, the first sentence is a hook, the second sentence provides background information, and the third sentence states the thesis statement, announcing the topic of the essay: the reasons for cats' popularity.
