Hi Lilian & Tantine

Could one of you please do the evaluation of this one? It's my translation, so I can't do it.

Hi Kafetzou,

"I would appreciate it if you (would) shed some light on this matter for me"

I'd remove that second "would" and use just the past tense.

Why?

Oh, just for being a conditional sentence, I think it should read conditional +if+ past.
Either
"I would appreciate it if you shed some light on this matter for me." or
"I would appreciate it if you could shed some light on this matter for me."

I'm sorry if I misunderstood the line.
Also there are two "been" in the first line.

Actually, I was guessing you were following that rule, and to be honest, I don't know why this one doesn't follow that rule, but I think it's because the word "would" here has a somewhat different meaning: "be willing to".
