The Present Simple with adverbs of frequency
Adverbs of frequency are often used to indicate routine or repeated activities, so they are often used with the present simple tense.
If a sentence has only one verb, place the adverb of frequency in the middle of the sentence so that it is positioned after the subject but before the verb.
For example: Tom never flies.
*We make question by using (How often)
Form :
How often + do / does+ subject + v (base) + C?
How often do you read novels?
I often read novels . / I read novels twice a week.
