Detailed ways

Please refer to Fig. 1 to Fig. 3, a kind of English grammar basic sentence pattern teaching device, it is made of main board, ground wheel, card case, card, peg, button, indicator light, control box, microprocessor, card reader , Speaker components. A ground wheel 2 is connected below the main body plate 1 , and a card box 3 is connected in an opening 13 provided on the bottom of the main body plate 1 , and a card 4 is placed in the card box 3 . Four pegs 5 are symmetrically fixed on the front left and right above the main board 1, and a control box 8 is fixed symmetrically on the back of it. In the control box 8, a microprocessor 9, a card reader 10, and a speaker 11 are respectively fixed. The card holder 10 and the loudspeaker 11 are respectively connected with the microprocessor 9 . English grammar basic sentence pattern table 12 is drawn in the middle of main board 1 layout, and button 6 and indicator light 7 are respectively arranged successively in five horizontal grids of English grammar basic sentence pattern table 12, and button 6 and indicator light 7 are electrically connected . The back of the card 4 is left and right symmetrically provided with electronic tags storing different contents.

How to use: First, randomly select a card 4 with five basic sentence patterns written on it from the card box 3, hang it on the two pegs 5 on the upper left of the main board 1 through the two holes on the card 4, and the card 4 The electronic label provided on the left side back, after being hung up, the content stored in the electronic label is read and pronounced by the card reader 10, the microprocessor 9, and the loudspeaker 11 in the control box 8 on the upper left of the main board 1, according to the letters on the front of the card 4 and the pronunciation Judge it is which kind of basic sentence pattern, after judging that it is accurate, correspondingly press one of five buttons 6 in the back of English grammar basic sentence pattern table 12, then the corresponding indicator lamp 7 of this basic sentence pattern lights up. The right or wrong way of judging is to remove the card 4 from the upper left and hang it to the upper right. The electronic label provided on the right back of the card 4 passes through the card reader 10 and the microprocessor in the upper right control box 8 of the main board 1. 9. The speaker 11 reads the pronunciation to determine whether it is correct.
