to say that someone is doing an action, you use the て form and います (formal)/いる (informal)
for example
彼女はりんごを食べる [かのじょはりんごをたべる] "she eats an apple", it can also mean "she is eating an apple"
but if you want to be explicit that she is eating the apple right now, you'd say
彼女はりんごを食べている [かのじょはりんごをたべている]
