What do you think is being tested in this sentence in regard to learning English?
"Sally often...........her lunch in a restaurant. Use a. has got b. is having c. has and d.have.
Sally often...........her lunch in a restaurant.
a. has got
=> Reason: position Ex: has often + past participle
b. is having
=> Reason: tense; i.e., adverbs of frequency + simple present, simple past
=> Reason: tense and position
=> Reason: position
Learners assume the verb stays in its base form; e.g., have because of its position after the adverb. It doesn't make sense, I know, but that's what they believe at first.
Sally often has (her) lunch in a restaurant
Sally often eats (her) lunch in a restaurant
Whether you use HAVE or EAT, the position is the same as they are both ordinary verbs, not auxiliary verbs, and as such they must follow the frequency adverb. It's as simple as that!!
