What are adverbs of frequency?
Adverbs of frequency explain how often something happens. The adverbs can be used when talking about the past, the present, or the future. But they are most often used to talk about the present tense, especially for beginners. Here are three example sentences: Sam always wakes up before the sun rises. They sometimes walk to school. I never got sick last winter. What is the sentence structure? Adverbs of frequency usually follow this structure: subject | adverb | main verb | object/complement She | never | drinks | coffee with breakfast. My teacher | always | knows | the answers. But when the sentence uses “to be,” the structure changes to: subject | main verb “to be” | adverb | object/complement Bill | is | usually | tired in the mornings. They | are | rarely | on time. The adverb can sometimes come at the beginning or end of the sentence. This gives more emphasis to the adverb, and so should only rarely be used. However, never, usually, and always never appear at the beginning or end
