Teacher: the central idea (theme) of the article refers to the central meaning expressed by the author in the article (including the author's views and attitudes, etc.) The central idea of induction belongs to the ability and requirement of grasping the ideological content of the article, which requires students to understand and analyze the article as a whole. In different genres of articles, the expression of the central idea (theme) is different: in argumentative writing, the central argument is the concentrated expression of the central idea; In expository writing, the characteristics of introduced things or explained things are the theme of the article; In all kinds of narratives, some opinions, understandings or emotions (including pros and cons) expressed by the author through writing people, narratives and things are the central ideas of the article.

Summarize the central idea of the article, mainly in the following ways:

First of all, start with the analysis of the title of the article.

Generally speaking, the title of an article can be a window to understand the content of the article. Some narrative titles directly reveal the theme of the article, such as "You shake my heart" in the 2003 Fuzhou senior high school entrance examination paper;

Others use words with metaphorical or pun meanings as titles to point out the center, such as "angel" in the examination paper of Kunming senior high school entrance examination in 2004. The titles of explanatory articles often show the main contents to be explained, such as "air longevity factor-negative oxygen ions" in the 2004 Fuzhou senior high school entrance examination paper. Some argumentative topics directly illustrate the argument, such as "creativity is more important than knowledge" in the Harbin 2004 senior high school entrance examination paper.

Second, analyze the topic sentences and key sentences of the article.

. Lyric and argumentative sentences in narrative mainly play the role of clarifying the theme, revealing philosophy or expressing the author's thoughts and feelings. Therefore, it must not be ignored in the reading process. For example, in "Who is the cutest person", the author wrote when talking about his thoughts and feelings on the front line in North Korea, "It is more and more profound to feel who is our cutest person!" Then, it is clearly pointed out that "our troops, our soldiers, I think they are the most lovely people." Then praise the noble qualities of volunteer soldiers directly with discussion sentences, point out their loveliness and reveal the center of the article.

Third, start with the analysis of the beginning or end of the article.

. The central argument in argumentative writing often appears at the beginning and end of the article. For example, in the article "Talk about backbone", the author clearly stated his point of view from the beginning: We China people have backbone! This is the central argument of this paper.

In addition, we can grasp the central idea of the article by combining the expression of the article. Expression serves to express the content of the article, so analyzing the expression of the article is helpful to summarize the center. For example, in the article "Praise of Poplar", the author praised the poplars directly, but actually praised the farmers in the north. The author uses symbolic means to express his will to express his center.

In addition, it should be noted that some articles do not directly point out the center, nor do they write sentences related to the center, so it is necessary to link the main idea of each paragraph of the article and make a comprehensive analysis.
