When writing a paper, there are some language expressions that need attention. First of all, try to spell and grammar correctly. It is very important to ensure that there are no word errors and obvious grammatical errors in the full text. Academic writing is very rigorous, and spelling mistakes can easily make people feel that their level is not high. In addition, writing sentences as simple as possible, each sentence contains only one meaning, which is very different from Chinese papers. Remember to use simple sentences. Generally speaking, even if you count clauses, try not to exceed two sentences. Third, avoid using spoken English. I wanted to find a website called Xiaoke's graduation thesis, but it passed. Now I think it would be terrible if it didn't pass. How many heroes are stumped by a paper? Learn to express yourself. Many times, engineering students just know how to work, but they can't express it. The expression ability is very poor, and others don't know what you want to express after talking for a long time. I think there are two reasons why it is difficult to express: First, thinking is jumping. When we solve problems, we usually have a flash of light and a leap of thinking. It's hard for others to understand jump thinking who gave it directly to others. Secondly, the language is inaccurate. Because many self-created languages will be used in daily work, or a term will have other uses instead of following the commonly used nouns and concepts in academic circles, it is easy for others to understand.
