Negative Sentences Answer Key

In this worksheet, students rewrite each positive sentence as a negative sentence by adding the correct helping verb and the word not. They must carefully determine which auxiliary verb fits the tense and meaning of the original sentence before converting it into its negative form. This activity reinforces understanding of how do, does, did, is, are, was, were, have, and modal verbs behave in negative constructions. Students practice accurate sentence transformation, building confidence in constructing grammatically correct negative forms. The exercise develops editing skills as learners focus on verb tense, subject-verb agreement, and appropriate placement of not. By working through a variety of real-life sentences, students strengthen everyday communication skills in writing and speaking.
