The document provides guidance on transforming affirmative sentences to negative sentences in Bangla. It outlines 10 different scenarios for how to make the transformation depending on the structure of the original affirmative sentence. Some key points covered include:
1. If the affirmative sentence contains "only" or "alone", it is replaced with "none but" or "nothing but".
2. Sentences containing "both...and" are changed to "not only...but also".
3. Sentences with "every", "a", or "all" are changed to include "there is/are no" followed by the verb.
4. Sentences with "too...to" are changed to "so...that"
