What is the past and present participle for mark?

Answer 1

"To mark" is a regular verb, which means it has a regular past tense (add an -ed). "The little boy marked the wall with a black pen." As for participles, they are also regular: For the present, you add -ing. "I am marking page 2 of this proposal; please look it over." And for the past, you use the helping verb "have" (or "has" for a 3rd person singular subject)-- "I have marked page 2, so please read my corrections carefully." "Maria has marked page 2, and she hopes you will look at it."
