Adverbs of Frequency + Present Simple for habitual actions

The Position of the Adverb in a Sentence

An adverb of frequency goes before a main verb (except with To Be).

Subject + adverb + main verb
I always remember to do my homework.
He normally gets good marks in exams.

An adverb of frequency goes after the verb To Be.

Subject + to be + adverb
