Explanation:

- The present continuous tense is used to describe actions that are happening at the moment of speaking or around the time of speaking.
- The structure always includes the subject followed by the appropriate form of the verb "to be" (am, is, are) and the present participle form of the main verb (ending in -ing).
- If the verb is already in its present participle form (e.g., "sleeping"), no further changes are needed.
