A random pairing component and English tense teaching device

Abstract

The present invention relates to an English teaching device, in particular to a random pairing component and an English tense teaching device, comprising a plurality of paired turntables arranged at intervals before and after, the front panel of the paired turntables is clamped with a writing board for identification through the slot of the writing board, There are multiple signal output points on the writing front panel, and multiple signal identification points for receiving signal output point signals on the back panel of the paired turntable. On the contrary, a braking mechanism that restricts the rotation of the paired turntable is provided in the arc cavity, and a control box is provided at the center of the paired turntable; the present invention can set phrases or words that produce tense changes on multiple paired turntables for the sentence structure , The pairing turntable can randomly match various tense sentences through the corresponding matching signal source, and display the different tense forms of multiple sentence patterns, which greatly improves the interactivity and intuition of English tense teaching and improves students' interest in learning.
