Hi Rosario,
I can't offer a resource,but here's a small comment.
I am writing a paper for a scientific journal and I would like to give a more formal style to my composition...
I have read many articles, but still most of them are written by non-native english-speakers, so they might not be good to use as a reference..
What I'm looking for is a resource that would give me hints on which prepositions, conjunctions, and expressions to use to sound more formal......
like... if I wanted to say "we should go"......I know that I would sound more formal if I said "it's high time we went"... No, 'high time' is an idiomatic expression that is less formal.
Any book or link containing this kind of suggestions?
Best wishes, Clive
