1. Adjust the sentences that affect the structure of the paper. On the premise of keeping the overall situation unchanged, we should sort out the order of papers, merge the original paragraphs and adjust the order of arguments, paying special attention to the preceding foreshadowing sentences to be taken care of later. For example, before losing weight, there is a saying that "this problem will be explained in detail in the later argument", but when losing weight, the later "detailed explanation" has been deleted, so it is necessary to adjust the previous bedding to avoid carelessness.
2. Adjust the sentences that affect the style of the paper. Some papers are simple in style and "speak" with a large number of objective facts. After losing weight, some facts are simplified and more statements are needed for discussion or debate. Some papers are sharp in style, and some extreme paragraphs and sentences are subtracted when the weight is reduced. At this time, it is necessary to add some objectively discussed sentences to unify the style of the whole paper.
3. Adjust the sentences that affect the fluency of the paper. After losing weight, some sentences will be incomplete, some sentences can't express meaning, and some sentences need punctuation. In the repetitive part of the paper, we can change the wording and express the original intention in other ways. For example, the active sentence pattern in the original text can be changed into passive sentence pattern, and the attributive prepositional sentence pattern can be changed into adverbial postpositional sentence pattern. For another example, before the weight is reduced, question marks are used in interrogative sentences, and after the weight is reduced, they can be changed to periods or exclamation points as appropriate.
To sum up, after the paper loses weight, there will be many problems in sentences, which need to be comprehensively considered from the aspects of structure, style and fluency, and carefully revised to achieve the purpose of optimizing the paper.
