Changing Affirmative Sentences to Negative Sentences

Turning positive sentences into negative ones is simple if you follow these steps:

1. Use "not":

   • Just add "not" after the helping verb (also called an auxiliary verb).
   • For example: "He plays football." becomes "He does not play football."

2. Matching the Subject and Verb:

   • Make sure the verb fits the subject.
   • For example: "She is happy." changes to "She is not happy."

3. Regular and Irregular Verbs:

   • For regular verbs, use "do," "does," or "did" with "not."
   • Irregular verbs work the same way.
   • For example: "They ate lunch." changes to "They did not eat lunch."

4. Different Tenses:

   • Present: "I am a student." turns into "I am not a student."
   • Past: "They visited the museum." changes to "They did not visit the museum."
   • Future: "She will help." becomes "She will not help."

Key Words:

• Helping Verbs: do, does, did, is
• Descriptive Words: happy, ready, sad

Practice these rules, and you'll get the hang of making negative sentences in no time!
