The past simple, past simple progressive, past perfect and the present perfect have been giving me the worst of all headaches recently. Can anyone correct me on this, please?
Let's say that I decided to set aside 2 hours yesterday to study, would it be correct to say: I was studying for 2 hours yesterday? Is it wrong to use the past continuous to emphasize the duration of something that was taking place at a certain point in the past?
Would it also be correct if I say: I was working for 2 hours yesterday, when something else interrupted me?
why is it correct or incorrect?
Can you also suggest a book that may help me with this?
