The conversion between affirmative sentences and negative sentences includes the conversion into single negative sentences and double negatives. After sentence exchange, the meaning will not change, but the meaning will change a little. Semantically, the single negative sentence is the lightest, the affirmative sentence is the heavier, and the double negative is the heaviest. Let's talk specifically about how positive sentences are transformed into negative sentences. First, the way to turn a positive sentence into a single negative sentence: first find out the antonym of the predicate and then deny the antonym. Through hard work, these problems can be easily solved. These problems are not difficult to solve through hard work. (negative sentence) 2. The positive sentence becomes a double negative 1. Methods: Double negation means affirmation, and the tone is stronger than the declarative sentence. Then rewriting just adds a double negative word before the predicate verb. 2. Common double negative words: no … no; ... uniformly ... no ... no ...; ... never ...; ... must ...; ... no, no, wait. 3. Double negative word substitution method: ① indicates judgment. "Yes" and "Le" use "No one can deny" ② to express great affirmation. "Must" and "must" use "must" and "have to" to express reluctance and necessity. "Only", "have to" and "have to" all mean everything with "have to". "All", "all" and "all" use "nothing, nothing" to indicate speculation. Yes, maybe, yes, should, no, no,no. He will come today. He can't come today. I want to work. I have to work. The patient needs to go to the hospital. The patient must go to the hospital. No payment will be made until the ordered goods arrive. Payment will not be made until the ordered goods arrive. (double negative) 5. Change affirmative sentences into multiple negative sentences, and when expressing negative meaning, make the number of negative components odd. We have to admit that the sun doesn't go around the earth. 6. Note: When an affirmative sentence becomes a double negative or negative rhetorical question, never say the meaning backwards. Note: Double negation means affirmation, and triple negation means negation (singular negation or explicit negation).
