Description

Technical Field

[0001] The present invention relates to the technical field of language learning equipment, and in particular to a foreign language grammar practice device. Background Art

[0002] Foreign language proficiency is a core skill in multinational corporations, foreign trade, science and technology and other fields. It allows one to directly participate in international project cooperation and negotiations and enhance career development opportunities. Therefore, mastering a foreign language can give one an advantage.

[0003] In the process of learning a foreign language, in addition to the factors of the language environment, most people improve their foreign language ability through memorization, recitation, reading and writing. This learning method is single and cannot form effective interactive learning. Long-term learning makes it difficult for learners to maintain sufficient interest and easily affects their enthusiasm for learning. Summary of the Invention

[0004] The purpose of the present invention is to overcome the problems in the prior art and provide a foreign language grammar training device that can eventually find phrases that can be combined into complete sentences through trial and error. This not only increases learners' learning interest, but also enables learners to quickly master grammar through real-time interaction, thereby increasing learners' learning enthusiasm and improving learning efficiency.

[0005] The present invention provides a foreign language grammar practice device, comprising a carrier, a plurality of entry sliders and an automatic prompt system; each entry slider corresponds to a phrase, and the phrases corresponding to the plurality of entry sliders can form a sentence; an arrangement area is provided on the carrier for sequentially arranging the plurality of entry sliders; the automatic prompt system is arranged in the carrier, cooperates with the entry sliders, and is used to automatically prompt whether the arrangement of the plurality of entry sliders is correct.

[0006] Through this design, the practitioner can choose from multiple entry sliders and arrange them in order according to their own learning understanding in the arrangement area; the automatic prompt system will automatically prompt based on the correctness of the entry sliders arranged by the practitioner.

[0007] Furthermore, opposite magnetic poles are provided at both ends of the entry slider; wherein, when the two entry sliders are arranged correctly, they attract each other head to tail, otherwise they repel each other; and the end wall of the arrangement area attracts the first arranged entry slider.

[0008] This design determines a correct arrangement of identification methods, whereby correctly arranged entry sliders can be attracted end to end, while incorrect entry sliders are held against their adjacent entry sliders. This allows the arrangement of the entry sliders to be preset.

[0009] Furthermore, the automatic prompt system includes a correct prompt mechanism and an error prompt mechanism, and both the correct prompt mechanism and the error prompt mechanism are arranged in conjunction with the entry slider.

[0010] Furthermore, the correct prompt mechanism includes a correct prompt plate, a connecting plate and multiple control components; the correct prompt plate is slidably arranged in the carrier; one side of the connecting plate is connected to the correct prompt plate, and the other side is elastically connected to the carrier; multiple control components correspond to multiple entry sliders, which are used to limit the connecting plate, and release the limit in turn when the multiple entry sliders are arranged correctly.

[0011] With this design, every time a correct entry slider is placed, the corresponding control component will release the limit on the connecting plate. When all control components are released, the connecting plate drives the correct prompt plate to pop out, achieving correct prompting.

[0012] Furthermore, the control component includes a first limit rod, a transmission gear and a driver; the first limit rod rotates and connects to the carrier, and is provided with a first limit tooth for limiting the connecting plate; the transmission gear is transmission-connected to the first limit rod; the driver is provided on the entry slider for driving the transmission gear.

[0013] With this design, after the correct entry slider is inserted and magnetically positioned, the driver on the entry slider is activated, driving the transmission gear to rotate, which in turn drives the first limit rod to rotate. After the first limit rod rotates, the corresponding first limit tooth releases the limit on the connecting plate. In some embodiments, the transmission gear and the first limit rod are connected by a belt drive.

[0014] Furthermore, the driver includes an elastic slider, a first rack, and a pushing block; the elastic slider is slidably arranged at the head of the entry slider and is elastically connected to the entry slider; the first rack is slidably connected to the entry slider; the pushing block is axially slidably connected to the entry slider, and one end of the pushing block abuts against the first rack, and the other end is slidably connected to the slide rail set in the elastic slider; wherein, the slide rail cooperates with the pushing block to push the first rack to engage with the drive gear.

[0015] With this design, after the correct entry slider is put in, due to the magnetic effect, the elastic slider is squeezed and slides toward the inside of the entry slider. Since the pushing block can only slide and displace along the axial direction of the entry slider, under the guidance of the slide rail, the pushing block slides outward, and the outer end of the pushing block pushes out the first rack; the specific slide rail is composed of an inclined area and a flat area. When the inner end of the pushing block finishes sliding in the inclined area, the first rack is just pushed out and engages with the drive gear. At this time, the elastic slider has not completely slid into the interior of the entry slider, and the flat area is used to maintain the pushing distance of the first rack when the elastic slider continues to be pushed in; when the entry slider is displaced due to magnetic attraction, causing the elastic slider to continue to slide toward the inside of the entry slider. At this time, since the first rack is already engaged with the drive gear, the displacement of the entry slider will cause the first rack to drive the drive gear to rotate, thereby realizing drive.

[0016] Furthermore, the error prompt mechanism includes an error prompt plate, a second limiting rod and a transmission assembly; the error prompt plate is rotationally connected to the carrier through a torsion spring; the second limiting rod is rotationally connected to the carrier and is provided with a second limiting tooth for limiting the error prompt plate; the transmission assembly is arranged in the carrier and is cooperated with the entry slider to release the limit of the error prompt plate.

[0017] With this design, when the entry slider is arranged incorrectly, the transmission assembly is activated, and the transmission assembly drives the second limit rod to rotate, so that the second limit tooth releases the limit on the error prompt plate, and the error prompt plate pops out under the action of the torsion spring.

[0018] Furthermore, the transmission assembly includes a contact piece, a rotating hook and a horizontal hook; the contact piece is elastically connected to the side of the entry slider; the rotating hook is rotatably connected to the carrier; the horizontal hook cooperates with the rotating hook to limit, one side is elastically connected to the carrier, and the other side is transmission-connected to the second limiting rod, which is used to rotate the second limiting rod to release the limit on the error prompt plate; wherein, a plurality of through holes are opened on the inner wall of the arrangement area, for the contact piece to pass through the through holes and abut the rotating hook to release the limit on the horizontal hook.

[0019] With this design, when the entry slider is arranged incorrectly, it is pushed out by the magnetic repulsion force, and the contact piece is always under the action of the spring. When it reaches the position of the through hole, the contact piece pops out, the entry slider stops moving, and the contact piece pushes the rotating hook through the through hole. The rotating hook releases the cooperation limit with the horizontal hook, and the horizontal hook moves under the action of the elastic force; in some embodiments, the horizontal hook is connected to the second limit rod through a first rack and gear structure. The displacement of the horizontal hook drives the displacement of the first rack, and then drives the gear on the second limit rod to rotate. After the second limit rod rotates, the limit on the error prompt plate is released.

[0020] Furthermore, the present invention also provides a method for using the aforementioned foreign language grammar training device, comprising the following steps: S1: Place the entry sliders into the arrangement area one by one; S2: The automatic prompt system automatically provides prompts based on the correctness of the arrangement of multiple entry sliders in the arrangement area.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention effectively helps learners understand foreign language grammatical structure and word order rules by loading phrase content into the entry slider and allowing learners to select and sort them in the arrangement area. Combined with an automatic prompt system that provides real-time feedback on the correctness of the arrangement, this helps learners improve their learning efficiency. It also enhances the interactivity and fun of the exercises.

[0022] 2. The present invention adopts a purely mechanical transmission design of a magnetic suction setting and an automatic prompt system. Without the need for electricity or electronic recognition, the arrangement order of the entry slider is used to automatically trigger the prompt mechanism, thereby achieving instant prompts for correct or incorrect sorting, reducing system complexity and maintenance costs, and having a wide range of applications and a low threshold for use.

[0023] 3. By setting up multiple control components, the correct prompt board will only pop up after all the entry sliders are correctly arranged and drive the internal transmission structure. This progressive feedback mechanism not only enhances the sense of achievement but also increases learners' sensitivity to word order accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by persons having ordinary skills in the field to which the invention belongs. “Include” or “comprising” and similar words mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. “Inside”, “outside”, “upper”, “lower”, “far”, “near”, “front”, “back”, etc. are only used to indicate relative position relationships. When the absolute position of the described object changes, the relative position relationship may also change accordingly.

[0028] The drawings in this invention are not drawn strictly according to the actual scale. The specific size and quantity of each structure can be determined according to actual needs. The drawings described in this invention are only schematic diagrams of the structure. Figure 1 -Attached Figure 16 .

[0029] Example 1 The present invention provides a foreign language grammar practice device, comprising a carrier 1, a plurality of entry sliders 2 and an automatic prompt system; each entry slider 2 corresponds to a phrase, and the phrases corresponding to the plurality of entry sliders 2 can form a sentence; an arrangement area is provided on the carrier 1 for arranging the plurality of entry sliders 2 in sequence; the automatic prompt system is provided in the carrier 1, and is provided in conjunction with the entry sliders 2, for automatically prompting whether the arrangement of the plurality of entry sliders 2 is correct or incorrect. The practitioner selects from the plurality of entry sliders 2 and arranges them in sequence in the arrangement area according to his or her own learning and understanding; the automatic prompt system determines whether the order of the entry sliders 2 arranged by the practitioner conforms to the grammatical rules, and thus automatically prompts, helping the practitioner to intuitively understand whether the phrase arrangement is correct. The word order judgment process in grammar learning is simplified, the interactivity and fun of the practice are enhanced, and it can be achieved by fully mechanical transmission, without the need for external energy, and has a wide range of usage scenarios. In addition, in this embodiment, the arrangement area is set as a track, and the entry sliders 2 are pre-placed in a drawer provided on the carrier 1. The phrases on different entry sliders 2 are correct and incorrect, as shown in the attached figure. Figure 17 shown.

[0030] Furthermore, opposite magnetic poles are provided at both ends of the entry slider 2; wherein, when the two entry sliders 2 are arranged correctly, they attract each other head to tail, otherwise they repel each other; and the end wall of the arrangement area attracts the first entry slider 2 arranged. A physical feedback mechanism for the correct arrangement of the entry sliders 2 is constructed through the physical properties of the magnetic poles. The correct word order arrangement causes the adjacent entry sliders 2 to form a magnetic adsorption connection; while the incorrect arrangement will cause repulsion due to the same magnetic poles, making it impossible for the entry sliders 2 to fully fit together, resulting in displacement. This structural design can achieve preliminary judgment through the magnetic attraction structure without the need for electronic identification, providing a physical basis for the judgment of the subsequent automatic prompt system. At the same time, the end wall of the arrangement area achieves the initial alignment of the entry slider 2 by magnetic attraction with the first section of the entry slider 2, further ensuring the stability of the entire arrangement process.

[0031] Furthermore, the automatic prompt system includes a correct prompt mechanism and an incorrect prompt mechanism, both of which are provided in conjunction with the entry slider 2. This allows the automatic prompt system to respond to correct and incorrect arrangement states respectively, and provide status feedback through corresponding mechanical mechanisms. By distinguishing the control logic corresponding to the correct and incorrect states, the device provides clearer prompt effects and enhances the interactive experience of the device.

[0032] Furthermore, the correct prompt mechanism includes a correct prompt plate 10, a connecting plate 13, and multiple control components; the correct prompt plate 10 is slidably arranged within the carrier 1; the connecting plate 13 is connected to the correct prompt plate 10 on one side and elastically connected to the carrier 1 on the other side; the multiple control components correspond to the multiple entry sliders 2, and are used to limit the connecting plate 13 and sequentially release the limits when the multiple entry sliders 2 are correctly arranged. Each time a correct entry slider 2 is inserted, the corresponding control component will release the limit on the connecting plate 13. When all the control components are released, the connecting plate 13, under the action of the elastic member (a spring in this embodiment), drives the correct prompt plate 10 to pop out, thereby providing visual correct signal feedback, prompting the learner that the arrangement is correct.

[0033] In this embodiment, the correct prompt board 10 is only used for prompting; in other embodiments, the correct prompt board 10 can also be pre-written with the Chinese meaning of the correctly ordered sentences using an erasable pen. Obviously, other conventional settings can also be made on the correct prompt board 10.

[0034] It's important to note that the number of control components is the same as the number of item sliders 2 that can be placed in the arrangement area. For example, in this embodiment, the arrangement area can accommodate a maximum of five item sliders 2, so there are five control components. If the grammar exercise only has three phrases (i.e., three item sliders 2) forming a sentence, then placing three item sliders 2 followed by two blank item sliders 2 will release all control components. It's important to note that the blank item sliders 2 are marked with the correct placement direction, so they won't repel adjacent item sliders 2.

[0035] In addition, in order to avoid incorrect judgment of different word orders, the corresponding types of entry sliders 2 should be marked with different colors, and the practitioner should sort them according to the corresponding color order. For example, the magnetism of the three entry sliders 2 of "He", "likes" and "you" is left N-right S. Then "He likes you" can be attracted to each other, but "He you likes" can still be attracted to each other. Therefore, the "he" category, "likes" category and "you" category should be marked with different colors in advance, and prompts can be given on the surface of the training device or next to the arrangement area that they should be arranged in a specific color order. Specifically, each category should include interference items, such as the "likes" category may include "like", the "he" category may include "him", etc.

[0036] Furthermore, the control assembly includes a first limiting rod 32, a transmission gear 24, and a driver; the first limiting rod 32 is rotatably connected to the carrier 1 and is provided with a first limiting tooth 15 for limiting the connection plate 13; the transmission gear 24 is transmission-connected to the first limiting rod 32; the driver is provided on the entry slider 2 for driving the transmission gear 24. After the correct entry slider 2 is placed and magnetically returned to its position, the driver on the entry slider 2 is activated, driving the transmission gear 24 to rotate, and then the transmission gear 24 drives the first limiting rod 32 to rotate; after the first limiting rod 32 rotates, the corresponding first limiting tooth 15 releases the limit on the connection plate 13. In this embodiment, the transmission gear 24 and the first limiting rod 32 are connected by a belt 31 to realize the transmission direction conversion or deceleration function, thereby further improving the transmission reliability and control accuracy. The action of the slider placement is fully utilized to achieve drive, avoiding additional operations.

[0037] Furthermore, the driver includes an elastic slider 9, a first rack 12 and a pushing block 11; the elastic slider 9 is slidably arranged at the head of the entry slider 2, and is connected to the entry slider 2 through a reset spring 29; the first rack 12 is slidably connected to the entry slider 2; the pushing block 11 is axially slidably connected to the entry slider 2, one end of the pushing block 11 abuts the first rack 12, and the other end is slidably connected to the slide rail 30 arranged in the elastic slider 9. Specifically in this embodiment, the pushing block 11 is located in the horizontal slide groove 28 opened in the entry slider 2; wherein, the slide rail 30 cooperates with the pushing block 11 to push the first rack 12 to engage with the drive gear 14. When the first rack 12 and the driving gear 14 are already engaged with each other, the displacement of the entry slider 2 will cause the first rack 12 to drive the driving gear 14 to rotate, thereby realizing driving. This driving mode can ensure the compactness of the mechanical structure while utilizing the operation action of the entry slider 2 itself to trigger the transmission behavior, thereby releasing the limit of the correct prompt plate 10.

[0038] Furthermore, the error prompt mechanism includes an error prompt plate 4, a second limiting rod 7, and a transmission assembly; the error prompt plate 4 is rotationally connected to the carrier 1 via a torsion spring. In this embodiment, the error prompt plate 4 is located in a placement slot 20 provided on the carrier 1; the second limiting rod 7 is rotationally connected to the carrier 1 and is provided with a second limiting tooth 27 for limiting the error prompt plate 4; the transmission assembly is provided in the carrier 1 and is provided in conjunction with the entry slider 2 to release the limit on the error prompt plate 4. When the entry slider 2 is arranged incorrectly, the transmission assembly is activated, and the transmission assembly drives the second limiting rod 7 to rotate, causing the second limiting tooth 27 to release the limit on the error prompt plate 4. The error prompt plate 4 pops out under the action of the torsion spring, providing an error prompt to the user. The linkage mechanism triggered by the incorrect arrangement realizes a prompt action without human intervention, thereby improving the interactivity between the device and the practitioner.

[0039] Furthermore, the transmission assembly includes a contact member 6, a rotating hook 3 and a horizontal hook 8; the contact member 6 is elastically connected to the side of the entry slider 2. In this embodiment, the contact member 6 includes a pressing ball 33, and a pressing spring 34 connecting the pressing ball 33 and the entry slider 2; the rotating hook 3 is rotatably connected to the carrier 1; the horizontal hook 8 cooperates with the rotating hook 3 to limit, one side is elastically connected to the carrier 1, and the other side is transmission-connected to the second limiting rod 7, which is used to rotate the second limiting rod 7 to release the limit on the error prompt plate 4. Specifically, a push plate 26 is provided on the rotating hook 3, and the contact member 6 presses the push plate 26, and the rotating hook 3 rotates to release the limit with the horizontal hook 8; wherein, a plurality of through holes 5 are opened on the inner wall of the arrangement area, for the contact member 6 to pass through the through hole 5 to abut the rotating hook 3 to release the limit on the horizontal hook 8. When the entry slider 2 is incorrectly arranged, it is pushed out by the magnetic repulsion force. The contact member 6 continues to be pushed outward under the action of the pressing spring 34 but is held against the inner wall of the arrangement area. When the entry slider 2 moves to the point where the contact member 6 corresponds to the through hole 5, the pressing spring 34 is no longer squeezed, the contact member 6 is ejected, and passes through the through hole 5 to push the rotating hook 3. The rotating hook 3 releases the matching limit with the horizontal hook 8, and the horizontal hook 8 is displaced under the action of the elastic force. In this embodiment, the horizontal hook 8 is connected to the second limiting rod 7 through the first rack 12 gear structure. The displacement of the horizontal hook 8 drives the displacement of the first rack 12, which in turn drives the gear on the second limiting rod 7 to rotate. After the second limiting rod 7 rotates, the limit on the error prompt plate 4 is released, completing the error prompt triggering. Specifically, in this embodiment, the main body of the second limiting rod 7 is a vertical shaft 21, and a transmission gear 24 is provided on the vertical shaft 21. The transmission gear 24 is engaged with the second rack 23. The second rack 23 is connected to the horizontal hook 8 through the sliding rod 22, and the horizontal hook 8 is connected to the carrier 1 through the compression spring 25.

[0040] Summary of working principle: When the practitioner begins practicing, they take out some entry sliders 2 and sort them in the arrangement area according to a specific color sequence until the number of arranged entry sliders 2 meets the pre-set number of sentence entries. Note that the color sequence must be correct. The automatic prompt system will provide prompts based on the correctness and incorrectness of the following: When the entry sliders 2 are arranged correctly in sequence, due to the magnetic effect, the elastic slider 9 is squeezed and slides toward the inside of the entry slider 2. Since the pushing block 11 can only slide along its own axial direction in the entry slider 2, under the guidance of the slide rail 30, the pushing block 11 slides outward, and the outer end of the pushing block 11 pushes out the first rack 12; specifically, the slide rail 30 is an inclined surface area and a flat surface area. When the inner end of the pushing block 11 slides in the inclined surface area, the first rack 12 is just pushed out and engages with the driving gear 14. At this time, the elastic slider 9 has not completely slid into the interior of the entry slider 2, and the flat surface area is used to maintain the pushing distance of the first rack 12 when the elastic slider 9 continues to push in; when due to magnetic attraction, the entry slider 2 is displaced, causing the elastic slider 9 to continue to slide toward the inside of the entry slider 2. At this time, since the first rack 12 is already engaged with the driving gear 14, the displacement of the entry slider 2 will cause the first rack 12 to drive the driving gear 14 to rotate. The transmission gear 24 then rotates the first limiting rod 32. Once the first limiting rod 32 rotates, the corresponding first limiting tooth 15 releases the limit on the connecting plate 13, allowing the arrangement of the entry sliders 2 to sequentially release the limit on the control components. After all control components are released, the connecting plate 13, under the action of the spring, causes the correct prompt plate 10 to pop out.

[0041] When the entry slider 2 is incorrectly arranged, it is pushed outward by magnetic repulsion. The spring forces contact member 6 to maintain its outward push, but it is held in place by the inner wall of the arrangement area. When the slider reaches through-hole 5, contact member 6 pushes through through-hole 5 to push rotating hook 3. Rotating hook 3 releases its restraint with horizontal hook 8, and horizontal hook 8 shifts under the action of the elastic force. Horizontal hook 8 is connected to second limiting rod 7 via a gear structure called first rack 12. The displacement of horizontal hook 8 drives the displacement of first rack 12, which in turn rotates the gear on second limiting rod 7. Rotating second limiting rod 7 releases its restraint on error prompt plate 4, which pops out under the action of the torsion spring, providing the user with an error prompt.

[0042] Example 2 On the basis of Example 1, in Example 2, in order to improve the versatility of the grammar practice device and increase the convenience of practicing handwriting exercises, a display board 16 and a writing board 17 parallel to each other are set on the carrier 1, the display board 16 is used to display the correct answer, and the writing board 17 is used for learners to write the answer. The display board 16 has a movable part 18 that moves along the length direction, and a roller curtain 19 is wound on the movable part 18, wherein the roller curtain 19 is wound on a reel, and the reel is rotated to connect the movable part 18, and a first torsion spring is sleeved on the reel, and the two ends of the first torsion spring are respectively connected to the movable part 18 and the reel, and the first torsion spring is used to make the roller curtain 19 rolled on the reel, and the end of the roller curtain 19 is connected to the end of the display board 16. After the movable part 18 moves, the roller curtain 19 can block or reveal the display board 16.

[0043] The initial position of the movable member 18 is on the right side. At this time, the movable member 18 pulls the rolling curtain 19 to unfold, and the rolling curtain 19 blocks the correct answer on the display board 16. When the learner gets the practice question, he writes the answer on the writing board 17 according to his own understanding. After writing is completed, the movable member 18 is moved to the left. At the same time, the rolling curtain 19 is rolled up on the scroll under the action of the first torsion spring, revealing the correct answer on the display board 16. The learner compares the written answer with the correct answer to judge whether his translation is correct, thereby practicing foreign language translation ability. The movable member 18 here is a movable frame.

[0044] Furthermore, the movable member 18 has an wiping member 38, which is used to erase the writing on the writing board 17. The end of the movable member 18 is fixedly connected to a T-shaped slider 35, which is slidably arranged in a T-shaped chute 36. The length direction of the T-shaped chute 36 is parallel to the length direction of the writing board 17. At the same time, there is sufficient friction between the T-shaped slider 35 and the T-shaped chute 36 to overcome the tension generated by the first torsion spring. The movable member 18 has a vertical The through groove 37 and the wiping member 38 are slidably connected in the vertical through groove 37. The wiping member 38 is located directly above the writing board 17. The wiping member 38 has an wiping layer or a wiping cloth on the side close to the writing board 17 for erasing the writing on the writing board 17. There is sufficient friction between the vertical through groove 37 and the wiping member 38, so that after the wiping member 38 is pressed downward or pulled upward, the vertical position of the wiping member 38 in the vertical through groove 37 remains stable during the movement of the moving member 18.

[0045] When the learner finishes practicing the first question and practices the second question, it is necessary to press the wiping member 38 downward so that the wiping layer or the wiping cloth contacts the writing board 17. When the movable member 18 is moved to the right, the wiping layer or the wiping cloth erases the written answer on the writing board 17, and the movable member 18 unfolds the roller shutter 19 to block the display board 16. The display board 16 here is preferably an electronic display board for displaying the correct answer to each question. When the roller shutter 19 blocks the display board 16, it is used to display the correct answer to the next question. After the learner writes the answer to the second question on the writing board 17, he pulls up the wiping member 38 to avoid erasing the written answer on the writing board 17 during the process of moving the movable member 18 to the left, so as to facilitate comparison with the correct answer.

[0046] When learners practice their foreign language translation skills: First, press the wiping member 38 downward so that the wiping layer or the wiping cloth contacts the writing board 17, then move the moving member 18 to the rightmost position so that the wiping layer or the wiping cloth erases the written answer on the writing board 17, and the moving member 18 unfolds the rolling curtain 19 to cover the display board 16, and the display board 16 displays the correct answer to the next question; After the learner writes the answer on the writing board 17, he pulls up the erasing member 38 and moves the moving member 18 to the leftmost end to avoid erasing the written answer on the writing board 17 during the process of moving the moving member 18 to the left, so as to facilitate comparison with the correct answer.

[0047] After the comparison is completed, repeat the above steps to practice your foreign language translation skills again.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
