ACT Grammar Review

Subject-verb agreement
A single subject needs a single verb and a plural subject needs a plural verb.

He (doesn’t, don’t) like it.
One of the boxes (is, are) open.
Each of these hot dogs (is, are) juicy.
The crew (is preparing, are preparing) to dock the ship.
Pronoun agreement, case, and clarity
Pronouns replace nouns (I, me, we, our, he, she, it, they, them, you)

Complete sentences vs. sentence fragments
A complete sentence has a subject and verb and is a complete thought.
So the battery would stay warm. (CS or SF)
Because the one I have now is not working well. (CS or SF)
Active vs. passive voice
Active = the subject of the sentence performs the action of the verb
Passive = the subject of the sentence does not perform an action
Active is more clear and concise. Shorter is better!
