Description

Adjustable reading device is used in chinese teaching

Technical Field

The invention relates to the field of Chinese teaching, in particular to an adjustable reading device for Chinese teaching.

Background

A Chinese is a multi-meaning word, usually used as a shorthand for language characters, language literature, and language culture. A chinese class is generally considered to be a comprehensive family of languages and cultures. The simple general names of languages and articles, language knowledge and cultural knowledge, etc. can not be separated from the text. It can also be said that the language is the sum of written or spoken language works formed by applying language rules and specific language words and the forming process, the language is a key teaching subject in the basic education course system, the teaching content is language culture, and the operation form is also language culture. The Chinese ability is the foundation for learning other disciplines and sciences, is also an important human and social science, and is a tool for people to mutually exchange ideas and the like. Has the unified characteristics of tool and humanity. The Chinese textbook generally teaches Chinese universal language characters (namely Chinese), and the linguistics is a generic term of the disciplines emphasizing the study of languages and characters from the aspect of documents, and generally comprises literary science, training, phonology, school and the like. Since ancient literatures are rich, characters are special, and languages are developed, the generalized languages should include linguistics, i.e., the general names of linguistics and literary works, but since linguistics in the international academic discipline are a large category, linguistics rather belong to linguistics, which becomes a branch of linguistics.
