Syllabus topic 4: Past Simple / Past Continuous / Past Perfect
Past Simple / Past Continuous / Past Perfect. Use past simple for the main sequence, past continuous for background in progress, and past perfect for an earlier event.
The idea
Use had + past participle for an action completed before another past event.
Structure & examples
By the time we arrived, the film had started.
I had eaten before I left home.
Notice the pattern
Had is the same for every subject. Use the past perfect when the order of past events needs emphasis or clarification. Once the sequence is clear, it is often unnecessary to put every verb in the past perfect. Already and never can appear after had.
The rain had stopped before dawn.
I had already packed my bag.
Important notes & common mistakes
Had takes a past participle, not a base verb.
Before you practice
First choose a form from the options. Then produce it yourself using the word or structure in the instruction. Finally, build complete sentences. Check the explanation after each answer and revisit any mistakes in your review list.
