Present Continuous

They  use the Present Continuous  to express the idea that something is happening now, at this very moment.

Examples:

• I am sitting.
• I am not standing.
• Is he sitting or standing?
• They are reading their books.
• They are not watching television.
• What are you doing?
• Why aren't you doing your homework?

 Sometimes, speakers use the Present Continuous to indicate that something will  happen in the near future. Fixed plan in the near future

Examples:

• I am meeting some friends after work.
• I am not going to the party tonight.
• Is he visiting his parents next weekend?
• Isn't he coming with us tonight?
•  She is going to Spain on Saturday.
