Learn about the past perfect continuous.
Practice 1: making the past perfect continuous
Complete these sentences with the word(s) in brackets using just the past perfect continuous. Remember to use contractions (I'd not I had) where possible.
Note: in questions 1-4 above, the past perfect simple is also possible. It makes a big difference in question 3 - he used the shampoo once, or many times!
Practice 2: differences in past perfect simple and continuous
Choose the best tense (past perfect simple or continuous) to complete the following sentences. Again, remember to use contractions. And remember that simple tenses are used for states or short, finished actions when we say how many. Continuous is used for long, unfinished or repeated actions. Finally, remember that sometimes both are possible (especially when it is both a long activity - continuous, which finished - simple).
