Have a look at the sentence:
“He stroded on, his face red, his fist clenched”
I wonder if there should be an "and" between the last 2 sentences or not? Like:
“He stroded on, his face red, and his fist clenched”
btw, what's the underlined structure called in grammar book? Independent structure? ( I learned this in Chinese and don't know its English name)
It would be fine with "and" but it's also fine without. It's a literary technique. Some writers will use the "and" there and some won't. Sometimes an author will use it and sometimes they won't. The main problem with the sentence is the word "stroded". It's incorrect. The past simple of "to stride" is "strode".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
