I am working on teaching an English grammar point to a group of students in an ESL course.
However, I am not aware of the grammar points that structure and allow this particular usage.
In the example sentences some of them read like Ann turned on the TV. + Ann sat down in her chair. -> Turning on the TV, Ann sat down in her chair.
or: I enter the bathroom. I see the water running. -> Entering the bathroom, I see the water running.
However, one specific example is tripping me up: Tomoki was born in America. Tomoki is good at English. -> Born in America, Tomoki is good at English.
However, the Tomoki answer seems confusing to me. Why is it not “Being born in America, Tomoki is good at English.” The specific reasoning I have for being confused is that Tomoki “was” is a different tense than Tomoki “is.” While in all the previous examples, the verb tenses and subjects were identical.
What makes Tomoki’s example work even though the verb tenses are different?
I appreciate any help in advance!
