When do I need past perfect instead of past simple?

Use past perfect when you have two past actions and you want to make clear which happened first: 'When I arrived, she had already left' (she left first). If the order is obvious or doesn't matter, past simple is enough: 'I arrived and she left'.

Do I use past perfect with both clauses?

No. Use past perfect only for the earlier event; past simple for the later one. Say 'After he had finished, he left' — not 'After he had finished, he had left'. Only the action that happened first gets the past perfect.

Which time expressions go with past perfect?

'By the time', 'before', 'after', 'already', 'just', 'never', 'when', and 'until' often appear with past perfect: 'By the time we arrived, the show had started', 'I had never seen anything like it'. These signal a sequence of past events.

Can I always use past perfect when something happened earlier?

Not always. If the order is already clear from words like 'before' or 'after', past simple often works fine: 'Before I arrived, she left' is acceptable. Past perfect is most useful when the sequence isn't otherwise obvious or when you want to emphasise that one action ended before another began.

How does past perfect work in reported speech?

Present perfect and past simple in direct speech often shift to past perfect in reported speech. 'I have finished' → 'He said he had finished'. 'I saw him yesterday' → 'She said she had seen him the day before'. The 'one step back' rule applies.
