*Levels of stress: 
Primary stress: We put a high mark ' before the syllable
Secondary stress: We put a low mark , before the syllable
Secondary stress only appears when the primary stress falls on the third syllable to the end of the word
Secondary stress precedes primary stress one syllable
Ex: conventional	 consumer	 conservation	 container
Note: 
- We often have a weak vowel before the stress
 In American English, the vowel “I” often becomes “ә” so we should be careful when we design the pronunciation test :
Ex: 	difficult	resident	president	pesticide 
	priority 	 resident	president	pesticide
