1. Mike drives a car now. (Incorrect placement of 'now' for Present Simple, this would be better in Present Continuous. However, following the structure provided, it's likely intended as a statement about his general ability or profession rather than a current action.)
2. Lara always gets up at 7 o'clock. (Habit/repeated action)
3. I don't drink tea in the morning. (Negative form for a habit/routine)
4. Do they paint a hospital? (Question form for a current action/state, though 'Are they painting...' is more common for this context).
1. He is waving goodbye to the children. (Action happening now)
2. She is usually late for school. (This is a statement of fact/habit, typically Present Simple. 'She is usually being late' is grammatically awkward and not standard. If the intention was a temporary situation, 'She is being late today' might be used, but 'usually' points to Present Simple.)
3. Are you painting a hospital? (Question form for an action happening now)
4. Mike isn't driving a car now. (Negative form for an action happening now)
Present Simple: Used for habits, routines, general truths, facts. Typically uses base form of the verb (V) or V-s for he/she/it. Questions often use Do/Does. Negatives use don't/doesn't.
Present Continuous: Used for actions happening now, at the moment of speaking, or temporary situations. Uses 'am/is/are' + V-ing. Questions invert the subject and verb. Negatives use 'am not/isn't/aren't' + V-ing.
Adverbs: 'always/usually/sometimes/never' often signal Present Simple. 'now/at the moment' often signal Present Continuous.
