I'm a S. Korean so eager to learn English. My friends and I keep practicing English, and we often run into sentences native speakers might find awkward. Please take a look at this. This is what my friend wrote.
1) We all are aware of that we are short on time.
I believe the word 'of' is followed by 'nouns', not 'subjects and verbs', right? So I suppose this needs to be rewritten,
2a) We are aware of the fact that we are short on time. OR
2b) We are aware that we are short on time.
Would you please help me know which one sounds okay? If none of them looks natural, would you please show me a good one?
