The document discusses the use of "used to" and "would" when referring to past habitual actions or states. It explains that "used to" is used for repeated actions or states in the past that are no longer true, like "I used to play with dolls" or "We used to go out a lot in the summer." In contrast, "would" can also refer to past habits but does not imply they are no longer done. The document also discusses how verbs like "get," "grow," and "become" can be used before "used to" to talk about becoming accustomed to something.
