1. Overview:
"Would do," "used to do," and "used to doing" are expressions that help us talk about habits, past actions, and preferences. They show how things were in the past or how we feel about things in the present.
2. Cases of Usage:
Case 1: "Used to do" is used to describe past habits or situations that are no longer true.
Example: I used to play soccer every Saturday.
Case 2: "Would do" is used to talk about repeated actions in the past, usually in storytelling.
Example: When I was a child, I would visit my grandparents every summer.
Case 3: "Used to doing" shows that someone is familiar or comfortable with something.
Example: She is used to studying late at night.
3. Exceptions or Things to Pay Attention To:
"Used to" is only used for past situations and cannot be used in the present. "Would" should not be used for past situations that are not habitual. For example, you cannot say, "When I was a child, I would break my leg." Instead, you say, "When I was a child, I broke my leg."
4. Additional Notes:
Common mistakes include confusing "used to do" with "would do." Remember that "used to do" refers specifically to past habits, while "would do" is more about actions repeated in the past. Additionally, "used to doing" is often misunderstood; it indicates comfort with a situation rather than a past action.
