This worksheet is an explanation of the structures used to, get used to and be used to. It is a general overview of these three structures with general examples and cover the affirmative, negative and interrogative forms. I used it to support the textbook "On Target 1", an intermediate I high school ESL textbook, and the theme that I used was "From Rags to Riches". The discussion and any other material presented within the unit was focused on the changes that people experience when they go from poor to rich fast. However, this worksheet can also be adapted for other units/themes and can also be elaborated upon to suit an advanced class.
