---------- Forwarded message ---------- From: lura dosa <luradsa@xxxxxxxxx> Subject: a grammar question Hello.. I have a question about the Present Perfect and I hope someone will help me. I know that when the time of the past action is specified, the Past Simple is used. But what about this: " On Tuesday, I _____________ (read) an article which I _____________ (think) would be suitable for my biology paper. I'm sure I _______________ (put) the article on my desk. I ______________ for it all over the house but ____________ it yet." Should 3 be Present Perfect or Past Simple? I know from the context that the putting happened on Tuesday, but also the effect "I'm sure" is present, so what to choose? Thanks for your help:)
