Choose simple or continuous from how the situation is viewed.
Use present simple for habits, repeated events, general truths, schedules, and states: I work from home on Fridays. This key belongs to Ana. It presents the situation without focusing on its internal progress.
Use am/is/are + -ing for activity around now, temporary situations, change, or repeated behaviour framed as temporary: I am working from home this week. Prices are rising. You are always losing your key.
I think the plan is risky. opinion/state
I am thinking about the plan. mental activity
The soup tastes salty. perception
The chef is tasting the soup. deliberate action
Keywords such as “now” help, but intended view decides the form. Cambridge Grammar Today distinguishes state, action, and event verbs and allows continuous forms when meaning becomes active.[1]
Write five pairs about work or daily life: stable vs temporary, habit vs activity now, state vs deliberate action, usual trend vs current change, neutral repetition vs annoyed repetition.
Ask “stable whole or unfolding view?” before searching for time words. Intended view usually decides aspect faster.
Use Cambridge verb types and British Council B1-B2 grammar for contrast exercises.
