---------- Forwarded message ---------- From: Alaa Nassar <alanassar59@xxxxxxxxx> Subject: I should have thanked you at once!(:) Hello Everyone.. I would like to thank all the teachers who answered my question about "at once". Now I have 3 other questions because grammar can be a puzzling thing sometimes. 1) I've come across the following sentence in an exercise about "Relative Clauses" in one of the grammmar books. What is the suitable Relative Pronoun here? : Give me an example of ________________ I can write "if" instead of "unless". 2) How would you change this sentence to reported speech? In this particular case, can we keep the tenses as they are in the "Direct Speech" sentence if the reporting verb is in the past? "We traveled to Italy when we had had enough money." : (He said they traveled to Italy when they had had enough money.) 3) Is "unless" used in the second and third conditionals? One book has examples of this in the different conditionals whereas many others don't. In advance, I truly appreciate your help and wish you a marvellous weekend:)
