Answer 2

We understood the lesson after the teacher had explained it to us.

• Both the simple past and the past perfect, sometimes known as the past perfect simple, indicate accomplished activities that occurred in the past.
• We use the simple past to describe what happened in the past, usually in chronological order.
• The past perfect indicates occurrences and acts that occurred before another action in the past (usually expressed in the simple past).
• Simple past tense examples:

1. Monica took a flight to London yesterday.
2. She checked in first, then proceeded to the gate.
3. Monica boarded the plane when it was finally ready for takeoff.

• Past perfect tense examples:

1. She was a bit concerned because she had never flown before.
2. When the flight attendants conducted the safety demonstration, she had already secured her seatbelt.
3. The plane took off once the flight attendants finished the safety presentation.
