Using Modals and Auxiliary Verbs

  1. Modals and auxiliary verbs are always followed by the base form of the main verb (without "to").
  2. Modals do not change form based on the subject (e.g., "I can," "he can," "they can").
  3. Auxiliary verbs change form based on the subject and tense (e.g., "I am," "he is," "they were").
  4. Use modals to express degrees of certainty, ability, permission, or obligation.
  5. Use auxiliary verbs to form questions, negative statements, and different tenses or aspects.

Common Questions and Answers

What is the difference between "can" and "may"?

"Can" is used to express ability or informal permission, while "may" is used to express possibility or formal permission.

When should I use "shall" instead of "will"?

"Shall" is often used in formal contexts, such as legal documents or official statements, to express obligation or future certainty. In most other cases, "will" is more commonly used.

To form a question using an auxiliary verb, place the auxiliary verb before the subject and the main verb. For example: "Are you studying English?" or "Have they finished their homework?"
