2. "He is appears.."
"Have you talked to John ,he appears to have been crying bitterly."
The structure of the verb ( to be + verb in present simple tense ) doesn't exist and is grammatically wrong.
You could use:
He has appeared
He is appearing
but never : "He is appears"
It is correct to use the verb "appear" in the present simple tense here:
" he appears" ,because it is a present action.
