To change an assertive sentence that does not contain a helping verb into an interrogative sentence, you use forms of the verb "Do" (Do, Does, Did).
The Transformation Method
Based on the provided reference, the method for transforming an assertive sentence that lacks a helping verb into an interrogative sentence involves introducing the appropriate form of "Do":
- Rule: If an assertive sentence does not have a helping verb (like is, am, are, was, were, has, have, had, will, would, shall, should, can, could, may, might, must), you construct the interrogative sentence using "Do," "Does," or "Did."
- Selection of "Do/Does/Did": The correct form ("Do," "Does," or "Did") is chosen based on the subject of the sentence and the tense of the original assertive verb.
- "Do" is used with plural subjects and the pronoun "I" in the present tense.
- "Does" is used with singular subjects (he, she, it) in the present tense.
- "Did" is used with all subjects in the past tense.
- After inserting "Do," "Does," or "Did" at the beginning, the main verb from the assertive sentence usually reverts to its base form.
Examples
Here is an example illustrating this transformation, as provided in the reference:
| Assertive Sentence | Interrogative Sentence |
|---|---|
| They play cricket. | Do they not play cricket? |
The reference also provides another assertive sentence: "Manaj reads English newspaper.", but its corresponding interrogative form is not included in the provided text. However, following the rule demonstrated, the interrogative would be formed using "Does" because "Manaj" is a singular subject in the present tense.
This specific method applies when the assertive sentence lacks a helping verb, utilizing "Do," "Does," or "Did" to form the question.
