Interpretation and analysis: double negation needs to be denied twice to express its positive significance. The tone of double negation is stronger than that of affirmative sentences, which plays an unquestionable role in further affirmation and strengthens the effect of affirmation. Generally speaking, double negation is divided into two discontinuous actions and a negative adverb without words.
According to the above principles and the original sentence "Everyone has a lot of unpleasant experiences in his life", double negation is carried out, and the keyword "impossible, no" is added, which is revised as: Everyone is impossible in his life, and there are not many unpleasant things.
Extended data:
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.
