Semester A Unit 3 Lesson 3

Introduction and Objective
Every text is written for a reason. Along with the purpose of the text comes the central idea, or what the text is about. Think about the different types of texts you have read in all your different classes. What was the idea behind some of them?

We see this with the use of nothing, slipped away, dying and an hour goes by on the same straight line…nothing is there.

Example 2:
Key West is an extraordinary habitat off the coast of the United States. A long sandy beach runs into the Atlantic Ocean. Barren dunes are home to many animals and creatures. This is a place families go on vacation year after year.
