would "lots of cats" be correct here? (just "......cats are eating" (no THE) was marked wrong.)
Is "At the moment" a preposition?
Is there a rule for placement of prepositions? Is it always (something like): Prep + Obj + Verb ?
or could I say: "nhũng con mèo đang ăn vào lúc này" ?
yes you can say "những con mèo đang ăn vào lúc này".
