Re: Voice tone meaning
I'm not really sure what you're asking.
We use our voice to emphasize.
A: The dog sat on the mat?
B: No, the cat sat on the mat.
A: The cat sat on the couch?
B: No, the cat ast on the mat.
A: How is Jim?
B: Oh such good news! You know how badly he broke his leg. But when I saw him yesterday, he was walking.
In these examples, there is no misunderstanding the position of the cat or what Jim was doing. But how we use our voice tells the listener what part of the information is new or important.
Is that what you mean?
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
