When 'become' means 'suit', can it be used in the progressive tense like
"His behavior was not becoming a governor."? I thought it's not possible, but the sentence sounds okay. What do you think? Thanks for your help!
"His behavior was not becoming a governor."? This is not incorrect, but might be better His behavior was not becoming of a governor. This doesn't sound quite right to me, though. Wait for further comments.
Then, "His behavior did not become a governor." -Does this have the same meaning with "His behavior was becoming of a governor."? I mean if "become" is used as a verb, the continuous tense is not okay, right?
Correct, except that you got your negatives mixed up.
I suppose because of the possible confusion (become has other meanings), "his behaviour did not become a govenor" is not a common way of putting it. "His behaviour was not becoming of a govenor" is not ambiguous and would be more likely to be heard.
You do hear, "that hat becomes you," though, since any possible confusion is promptly eliminated by the realisation that a hat cannot change into "you."
