Progressive tenses are verb forms that express an ongoing action or state. They are formed by combining the auxiliary verb "be" (in the appropriate present, past, or future tense) with the present participle of the main verb (which usually ends in "-ing").
Here's a breakdown of progressive tenses:
* Present Progressive: Describes an action happening now. (e.g., "I am walking," "They are playing")
* Past Progressive: Describes an action that was happening in the past at a specific time. (e.g., "I was sleeping," "They were eating")
* Future Progressive: Describes an action that will be happening in the future at a specific time. (e.g., "I will be working," "They will be traveling")
Example:
* Simple Present: "She works at the library." (This is a general statement about her job.)
* Present Progressive: "She is working at the library right now." (This indicates that she is currently working at the library.)
