3 NOTES: PHÂN BIỆT 2 THÌ PAST PERFECT SIMPLE - to indicate that a completed action happened earlier than something else. Ex: By the time I was 15, my father had taught me how to drive a car. The Past Perfect simple emphasizes completion (or the result of a completed action) Ex: By the time we arrived, he had left the house. PAST PERFECT CONTINUOUS - often creates a kind of background for the rest of the sentence. Xét ví dụ sau: - Jane had been browsing the Internet for about fifteen minutes when she suddenly noticed it was completely dark outside. - Nhận xét: We cannot use the Past Perfect in the above sentence because the action was not completed. (In other words, she did not stop browsing the Internet immediately after looking out of the window) The Past Perfect Continuous emphasizes the duration or activity of an action. Ex: By the time we arrived, he had been playing poker with his friends for 2 hours.
