Final answer:
The question seeks the title of a book where the protagonist desires to learn his native language but does not know it; however, no specific book is identified from the excerpts provided. The themes mentioned suggest an exploration of language and identity.
Step-by-step explanation:
It appears that the student is asking about a narrative in which the main character desires to learn his native language but does not know it. While the provided excerpts do not clearly point to a specific book, they do cover themes related to language, identity, and communication. For instance, one excerpt refers to a boy learning Chinese works on astronomy, which might suggest a desire to connect to his cultural roots. Another excerpt mentions a student who only knows what's written in books, hindering his understanding of a Nightingale's song, implying a gap between book knowledge and practical understanding. Additionally, the reference to the loss of native languages suggests the theme of language and cultural identity. It appears the student's question might be explorative in nature, perhaps related to themes of language and self-identity rather than querying about a specific book.
