Dear hankuri: Perhaps it would be helpful if you gave some examples of sentences illustrating your problem.

With regard to your second question, I have trouble grasping what you are trying to describe. It might be helpful if you re-phrased the question to make it more clear.
This is not intended as critcism, just confession of my own modest talent. Do post again, the Board welcomes new contributors, and has members better qualified to comment than I am.
