In English Grammar, Subjects & Verbs in any sentence must agree. The Grammar rule here is that a Singular subject should have a corresponding verb that is singular.
The Subject-Verb Question Kit helps you practice this Grammar rule, through a series of Multiple Choice Questions. Practice how to identify the 'true' subject in a sentence, and how to handle special sentence structures, such as those with Compound Subjects.
You will also practice navigating the prepositional phrases and modifiers in longer sentences, so that you don't get confused on the 'true' subject.
In this Question Kit, I've included Verb Tense Agreement question sets, just to complement the 'Verb Vibe' and give you practice on Verb Tenses as well.
