The following sentences come from a dictionary compiled by a Chinese teacher of English：
1. No one of you could lift it. (Grammar books tell us to use 'none of...'.)
2. He can be ill at any time. (We say 'He can be very careless/ill', but
can we say 'He can be careless/ill at any time'?
Are they correct English? Or do you native speakers say such things?
Thank you in advance.
1. "None of... or Not one of..." either one is correct.
2. "He could be ill at any time." is better, but an unusual sentence.
