The stress in the sentence

In spoken English, to emphasize a word from the sentence, we
use the rhythm. We pronounce the word strongly (with much
strength and with a tone more high). 

1. The stress in the sentence
As a word has a stress, a sentence has stresses too. The sentence
stress  is the stress on some specific words.
Examples:
You will come the next week. Won’t  you?
 Not this week.

To emphasize the subject, we stress it:
Frank did  it.

I paid.

Emphasizing an auxiliary express a contradiction with

What it said before:

You are not aware of the trip.

 I am.

He didn’t come, after all.

We add do or does or did to a base form to emphasize the verb:
You didn’t see!

I  did see.

Unstressed syllables very often have the sound /É™/.
/É™/  glas/É™/ s /É™/ f water
/É™/ pair /É™/ f books
/É™/  book /É™/  bout /É™/  meric/É™/  
She takes h/É™/  r brekf/É™/  st 
I want t/É™/   go t/É™/ Californi/É™/  

2. Rhythm 
 
Rhythm is also important in a speech. It refers to keep 
the same time between stressed words in a sentence.
Example:
Frank enjoys reading books. (Four syllables and four syllables stressed.)
As you might know, It will be a nice day tomorrow.
(Twelve syllables and four syllables stressed.)
We take the same time to say these two sentences.

3. Intonation: 
  
The intonation depends on the voice and the tone. Rinsing and
falling tones of the language give more than a meaning to the
sentence.
Examples:
Question:
Are you ready?
Didn’t he come yet?
Exclamation:
What a beautiful day!
That’s too bad!
Tag question:
It has a falling tone and provides a comment 
or gives an opinion. The speaker expects the other 
person to agree.
You didn’t call yesterday. Did you?
The street is crowded. Isn’t it?
Falling: sure
Increasing: with an exclamation mark: not sure
