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.

  1. He was bored because all day. (it, rain)
  2. Her English was good because it for years. (she, study)
  3. I knew that my shampoo without asking. (he, use)
  4. We didn't know what to do because to the teacher. (we, not, listen)
  5. Before the accident, ? (he, drink?)

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).
