He never imagined that a 12-year-old child had such ambition and mind to change negative sentences.

Negative sentence: He can think of a 12-year-old child with such ambition and mind.

He didn't expect a child of 12 years old to have such ambition and mind. The key point of the sentence is "he didn't expect it", so when it is changed into a negative sentence, it should be denied. Instead of the following "I have such ambition and mind", this sentence is only an elaboration of what I didn't expect, not a negation of the subject.

The rewriting of negative sentences often uses negative words, such as adverbs "bu", "fu", "wu", "bie", "wei", "bu" and "wu".
