=====================
I am deeply moved by your spirit of helping others.As a chinese saying goes:"You are never tired of teaching others".
The first one,"There is no surgical patient I cannot treat competently , treat just as well or better than other surgeon."from a Chinese magazine.The second one,"it was time for her to come out, charge out, into what they called society."from J.D Salinger,a modern American writer.
According to your explain,you added "and " before the second "treat", for the first one,then for the second one , we can put "or" before "charge ".In my eyes, both and and or are conjunctions and the elements they join are alike,too .This shows the fact is common.So I think both of them , one without and , one without or ,are good Engish.Do you agree with me now?Or in short,is the first sentence ok?Is the second sentence ok?Please directly teach!I don't want you to correct them.Thanks a lot!
