"She is eating."
C'est means she/he/it is + NOUN
Two rules for you:
- C’EST – CE SONT In French, "c'est" (sing.) and "ce sont" (plural) are used in a large variety of expressions, when a pronoun (it, she, he, they) is subject of verb "être" and followed by a nominal group, ie: article (+ adjective) + noun.
- it is + noun => c'est + article + noun
- she is + noun => c'est + article + noun
- he is + noun => c'est + article + noun
they are + noun => ce sont + article + noun
CONTINUOUS PRESENT In English, to mean that an action is in progress at the time you speak, you use the continuous verbal form, ie verb BE + action verb in the gerund form (-ing). o he is eating means he currently eats In French, this verbal form does not exist (directly translated “il est mangeant” is incorrect). Therefore, you can translate either “il mange” or “il est en train de manger”, where the construction verb être + en train de + infinitive correctly expresses the English continuous form.
