English Grammar: Transforming Interrogative to Statement

The question asks us to convert a specific type of question, an interrogative sentence, into its corresponding statement form. The original sentence is: 'Is she not changing her dress?'

Understanding the Original Sentence

• Type: It's a question (interrogative).
• Form: It's negative (contains 'not').
• Tense: It's in the Present Continuous Tense. The structure for a negative interrogative in this tense is: 'Is/Am/Are + Subject + not + Verb-ing + ... ?'

Converting to a Statement

To change a negative interrogative sentence in the Present Continuous Tense into a statement, we rearrange the words:

1. Place the Subject first.
2. Follow with the auxiliary verb 'is' (since the subject is 'she').
3. Include the negative particle 'not'.
4. Add the main verb in its '-ing' form (present participle).
5. Complete the sentence with the rest of the object/complement.

The resulting structure for the statement is: Subject + is + not + Verb-ing + ...

Analyzing the Options

Let's examine the given options based on this structure:

• Option 1: 'She will not change her dress' - This is in the Future Simple Tense, not the Present Continuous Tense.
• Option 2: 'She was not changing her dress' - This is in the Past Continuous Tense, not the Present Continuous Tense.
• Option 3: 'She will change her dress' - This is in the Future Simple Tense and is affirmative, not negative.
• Option 4: 'She is not changing her dress' - This matches the required structure: Subject ('She') + auxiliary verb ('is') + negative ('not') + present participle ('changing') + object ('her dress'). It correctly reflects the original sentence's meaning and tense in statement form.

Conclusion

The sentence 'Is she not changing her dress?' is a negative interrogative in the Present Continuous Tense. The correct statement form follows the pattern: Subject + is + not + Verb-ing. Option 4, 'She is not changing her dress', perfectly fits this requirement.
