Cleft sentences consists of a be-verb, right?
However, can the be-verb be be-verb forms other than "is" or "was"?
Are both examples correct?
Example 1
What he did could have been make fun of others.
I mean here, "Maybe he made fun of others."
Example 2
What he did should have been finish the work quickly.
I mean here, "he was supposed to finish the work quickly."
