i really don't know how i can explain this or what this is called so, here are some basic examples: 1- i shoved the food in my mouth as he walked beside me. 2- i grab his arm, taking him with me as he struggles to catch up. now that you know what i mean (i think), i have some questions! 1- is it grammatically correct to use "as" in this way? 2- does using "as" in this way portray that i know what I'm doing as a writer? 3- in what ways can i substitute this? please help! I'm a beginner at this sort of thing.
