There is a double negation in negative sentences. There are two negative adverbs in the sentence, such as "no … no", "no … no" and "no … no". The affirmation and negation of double negative meaning, the weight of tone, and the application of this sentence pattern and rhetorical question.
The function of double negation
Double negation not only strengthens the tone, but also weakens it. Whether the double negation strengthens or weakens the tone depends on the specific sentence pattern and context.
Generally speaking, the sentence pattern of negative adverbs (or verbs with negative meanings) plus rhetorical mood strengthens the mood; In the two sentence patterns of negative adverbs and verbs with negative adverbs and negative meanings, in addition to emphasizing mood, some of them, that is, suggesting speculation and situation, are more euphemistic and powerless than simple affirmative sentences. Therefore, the double negation cannot be generalized. When reading and using, it should be carefully distinguished according to the specific situation.
