Used to describe something that will happen very soon, almost immediately.
“The waitress is about to drop the plates because the tray is too heavy.”
“The cyclist is about to hit the pothole if he doesn't swerve.”
In Task 4, you often need to describe the very next moment after the picture, and 'is about to' is perfect for that immediate, split-second prediction. Use it right at the start of your response to set up the scene, e.g., 'The boy is about to jump into the lake.' This phrase helps you sound natural because it matches exactly what a person would say when watching an event unfold in real time.
Synonyms: is on the verge of, is going to, is just about to
