We use frequency adverbs like sometimes or usually with the present tense explain how often things happen.
Actual frequency of adverbs can be seen below:
|Always||Usually / Normally||Often / Frequently||Sometimes||Occasionally||Seldom||Hardly ever / Rarely||Never|
When we use frequency adverbs with the present simple, the adverb comes before the main verb in the sentence:
- I always eat a lot of vegetables.
- We usually visit my parents every weekend.
- I sometimes go to the gym. (also: Sometimes I go to the gym).
- I seldom finish work before 6 pm.
- I rarely read newspapers any more.
- I never
BUT in some cases with the verb to be, they come after the verb:
- I am usually late for school.
- You are never on time.
If you put them at the beginning or end of a sentence, this adds emphasis:
- Usually I am late for school.
- I am late for school usually.
