The double negative sentence is:

1. Peanuts have many benefits, and no one dislikes them.

2. Peanuts have many benefits, and everyone likes them.

Double negative means negating it twice, which means it has a positive meaning, but it must have a negative meaning in it.

The negative form of Chinese can be found by subtracting the absolute proposition from the negative proposition. From this, it can be concluded that there are two negative forms in Chinese: one is negative words, which are composed of lexical means in a general sense. The negative form; the second is the rhetorical question mood, which is a negative form in a special sense formed by grammatical means.

Based on this, it is inferred that there are two types of negative sentence patterns in Chinese: one is the general double negative sentence pattern, which is caused by using two negative words together (such as: have to); the other is the special Double negative sentence pattern; this is caused by using a negative word with an ironic mood. Double negatives have functions such as expressing affirmation and strengthening the tone.

The structural form of double negation:

(1) Double negation in a single sentence.

1. "No (no, non) + verbal component + no". This form is composed of a negative word followed by a verbal component, and then combined with a negative word. The latter negative word can often only be "no", not "no". For example: No abnormality was found. It is not enough to bring peace to the world without killing.

2. "Not + negative word". In this type of double negative structure, the first negative word "no" followed by "yes" forms a negative judgment and is then combined with a negative form. "Yes" here is a judgment verb, which is a judgment on the negative content behind it. For example: Not without difficulty.

3. "Can't + willing verb + negative word". This type of double negation is also called a willing double negation. The middle component of the two negative words is a willing verb. For example: You won’t stop doing it. He had to go.

4. "No (nothing, not) + nominal component + negative word". In this type of double negation, the first negative word is followed by a noun component, and the negative component after the second negative word is not related to the first negative word. For example: There is no one who does not admire him.

5. "Use two negative words together." Two negative words appear consecutively without being interrupted by other elements. Two negative words can be "nothing", "no", "without". For example: It’s not without its difficulties. Not without its shortcomings.

(2) Double negation in complex sentences or contraction sentences.

Some scholars believe that double negation is limited to single sentences. Through analysis, we can easily see that there are also structures in which double negation expresses affirmation in some complex sentences or condensed sentences. For example: without agriculture, there would be no light industry. Never give up until you achieve your goal.

(3) Negative words + interrogative mood (words).

This type of sentence pattern is based on the structure of a rhetorical question, in which negative words are used to express a positive meaning. In this type of sentence, the interrogative mood is an indirect form of negation, so we can think of it as a special type of double negation. For example: Aren’t you that annoying person? Don’t I want to get married?
