Pronoun case exercise 1

Grammar review Use a subject pronoun (I, he, she, we) when it's doing the action, and an object pronoun (me, him, her, us) when the action is happening to it. The confusion usually shows up in pairs, like "him and I" or "we girls."

Quick test: take the other person out and see which pronoun still sounds right on its own.
"Help him and I" → drop "him and": "Help I"? No. It should be "Help him and me."
"We girls have been working hard" → drop "girls": "We have been working hard" still sounds right, so we is correct here.
