REMEMBER Statal Verbs
Past Continuous vs. Past Perfect Continuous USE 2 Cause of something in the past Using the Past Perfect Continuous before another action in the past is a good way to show cause and effect. Examples:
If we 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 because this can change the meaning of the sentence. Past Continuous emphasizes interrupted actions, whereas Past Perfect Continuous emphasizes a duration of time before something in the past. Study the examples below to understand the difference. Examples:
This sentence emphasizes that he was tired because he was exercising at that exact moment.
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. It is important to remember that Statal Verbs cannot be used in any continuous tenses. Instead of using Past Perfect Continuous with these verbs, you must use Past Perfect. Examples:
