The first part (1 paragraph) directly puts forward the central argument of the article: "human talent mainly comes from diligent study", which denies the theories of "natural knowledge" and "genius".

The second part (paragraph 2) emphasizes the importance of learning by explaining the relationship between learning and talent.

This passage can be summarized into three meanings.

The first level (sentence 1) clarifies the relationship between learning and talent.

The second layer (the second sentence) further points out that the key problem of learning is "willing to learn, dare to learn" and emphasizes the attitude of learning. "Willing to learn" means "diligence" and "daring to learn" means "courageously marching forward despite difficulties".

The third layer (sentences 3 to 6) clearly points out that the talents of "genius" and "prodigy" come from acquired efforts and "diligent study".

The third part (paragraphs 3 to 5) starts from many angles and proves with sufficient examples that "talent comes from diligent study".

The fourth part (paragraph 6) ends with some questions. The author once again quotes famous sayings and touching deeds of Marx, emphasizing and highlighting the central argument: "Genius comes from hard work".

The ending can be divided into three levels.

The first level (sentence 1) is a connecting link. "In short, people's talents are mainly acquired through hard work." The previous paragraphs are highly summarized and summarized, and directly summarized into a central argument, which is very clear and prominent.

The second layer (2-6 sentences) quotes Newton, Edison, Mendeleev, Gorky and China respectively, proving that "genius" comes from diligence.

The third layer (the last three sentences) takes Marx's practice as a shining example, profoundly explaining that "genius comes from diligent study" and encouraging everyone to study hard and work hard.
