The word "author" often appears in academic papers, reportage and critical news reports. Its appearance gives a hint, which only represents my personal opinion. From the range of its appearance, we can also find that it usually takes a personal view. There are many self-proclaimed words, such as "Yu", "Wu", "A", "Yu", "fool", "I" and so on. The reason why such words are used instead of others is that they have a certain literary flavor on the one hand, but they are not very classical. Moreover, if you express your personal views too directly, you will appear conceited; If you are too modest, you will be unconvincing. The use of the word "author" can well show an appropriate euphemism. On the other hand, disyllabic words are more rhythmic than monosyllabic words. One of the characteristics of our Chinese is that there are a large number of disyllabic words. For example, when saying "I want to", "I" will usually delay a little, make up two beats, or at least make up one and a half beats; And just saying "I think" won't happen.
In fact, in some places, it is customary to use the word "author" instead of "I". Sometimes there is no way to fully prove why you use it like this. As for the argument that it will be confused with the protagonist, there is indeed some truth. But the word "author" rarely appears in novels, so I still beg to differ.
The author is the general name of the author of the article. The pen here means "write" The author is the person who wrote this article and agrees with the author. Generally, it will appear in articles introducing other people's works, such as the author's use in his own articles, so as not to be confused with the first person in the article. For example, at the beginning of A Dream of Red Mansions, Cao Xueqin expressed his thoughts in the poem "Dou Yun's author is crazy, who can understand the taste". The meaning of "author" and "author" is the same. If "I" is used here, Cao Xueqin will be confused with Jia Baoyu.
