Past Continuous VS Past Perfect Continuous
Compare was -ing (past continuous) and had been -ing:
• It wasn’t raining when we went out. The sun was shining. But it had
been raining, so the ground was wet.
• Katherine was lying on the sofa. She was tired because she’d been
working hard.
Past Continuous VS Past Perfect Continuous
If you do not include a duration such as for five minutes, for two weeks, or since
Friday, many English speakers choose to use the past continuous rather than
the past perfect continuous.
!!!Be careful!!! Past continuous emphasizes interrupted actions, whereas
past perfect continuous emphasizes a duration of time before something in
the past.
Examples:
• He was tired because he was exercising so hard.
This sentence emphasizes that he was tired because he was exercising at that
exact moment.
• He was tired because he had been exercising so hard.
This sentence emphasizes that he was tired because he had been exercising
over a period of time. It is possible that he was still exercising at that moment
OR that he had just finished.
