College english is read and is used books strutting arrangement

Technical Field

The application relates to a book supporting device, in particular to a book supporting device for college English reading.

Background

English is the official language (as the native language) specified internationally and is the most widely used language in the world, and english contains about 49 ten thousand words, plus about 30 ten thousand technical nouns, is the language with the most vocabulary, and is also the official language of the european union and many international organizations and the state of the english federal, and has the third highest number of native language users in the world, next to the number of native language users in chinese and spanish. English evolved from ancient languages spoken by ozu, saxon and witter in scandinavia peninsula, denmark, the netherlands and the surrounding migrants to british isles, and was spread throughout the world by the colonists in the united kingdom. Since the Chinese language was historically exposed to various national languages, its vocabulary was changed from unary to multiple, and the grammar was changed from "more inflected" to "less inflected", and the speech was changed regularly. The world's leading position in the uk and the united states of culture, economy, military, politics and science in the 19 to 20 th century has made english an international language. Today, many international occasions use english as a communication medium.
