in words

2. Stressed words are:
the important words of the sentence, the words that comprise the contents of the dialog and help the listener and speaker focus on the same information
said with a slight pitch change, a little louder, or for more time than surrounding words
used to create the underlying rhythm of English.

7. Intonation
It gives us clues about the attitude of the speaker, how he feels about what he is saying.
We can get a good idea, for example, as to whether someone is interested, bored, being honest or lying and so on.

8. Two basic patterns of intonation created by David Brazil
Refering tones (r)
Proclaiming tones (p)
Fall-rise tone: The speaker is referring to information that he presumes to be shared between the speakers.
In questions we use referring tone to make sure what we are saying is correct,or to check information.
Falling tone: used to indicate that the speaker is expressing information that is presumed to be new, or is adding something to the discussion.
We also use it to give facts, express opinionswe believe to be true, or to ask fornew information.
