Foreign language tense demonstration device

Technical Field

The utility model belongs to the technical field of the teaching articles for use, specifically, relate to a foreign language tense presentation device.

Background

At present, English is the most commonly used foreign language and is an important subject of examination in China, and English tense teaching is one of important grammar knowledge teaching throughout middle school and even university. At present, in the english teaching process, different tenses are used to represent different times and states, and are verb forms representing actions, behaviors and states under various time conditions. There are 16 tenses in English, including the general present time, the general past time, the general future time, and the general past future time; when the current process is performed, when the previous process is performed, when the future process is performed; when done now, when done in the past, when done in the future, and when done in the past, the english tense has been widely used in english daily conversations, reading comprehension, writing, translation, and the like.

Because of the difference between English and Chinese, students often have confusion and ambiguity in learning from the structures and usages of various tenses or the common time-oriented languages of tenses. When a teacher teaches the content of English tenses, example sentences are often written according to the pronunciation method of the propaganda department, the example sentences are repeatedly explained, are boring and boring, are not vivid and are not vivid, so that students can memorize the structure, the usage and the example sentences of different tenses mechanically in the repeated teaching of the teacher, the understanding and the application of the students to the English tenses can be wrong, the teaching quality is poor, and the interest of the students in English learning can be influenced.

The demonstration content can include a concept of a tense, a common time, a basic structure, a negative form, a general question sentence form, an example sentence and the like, or a part of the content, as long as the content is used for the students to learn the tense.

The utility model discloses still including making this foreign language tense presentation device normal use's other subassemblies, all can carry out conventional setting according to prior art. In addition, the devices or components of the present invention which are not limited in this application all adopt the conventional means in the art.

The utility model discloses a foreign language tense presentation device's effect principle does: the demonstration boards can be contrastively analyzed between the tenses demonstrated on the same group of demonstration boards, at the moment, the rest groups of demonstration boards can be moved to the other side of the door arch-shaped bracket, the same group of demonstration boards for comparison can be moved to the other side of the door arch-shaped bracket, the interference of the rest tenses is prevented, any tense demonstration boards among different groups can be contrasted, the corresponding contrasted tenses are moved to the uppermost end of an observable area on the door arch-shaped bracket and are positioned at the same horizontal line, the rest demonstration boards are moved to the other side of the door arch-shaped bracket or the lower end of the door arch-shaped bracket, the interference of contrasting tenses is avoided as much as possible, two or three independent contrasts can be carried out similarly, the demonstration boards can be observed by both sides of the door arch-shaped bracket, when the demonstration boards are moved to different sides, only the demonstration boards need to be rotated, the demonstration contents are turned to an observable angle (generally turned over by 180 degrees), when the demonstration board moves, take off positioning magnet from door arch-shaped support, when treating that fixed subassembly moves to required fixed position, place positioning magnet in the shift ring below, realize the location.

The utility model discloses a foreign language tense presentation device is through reasonable structure setting, makes things convenient for the contrastive analysis between different tenses, is favorable to the learner to understand the memory to the deepening of tense, demonstration board's removal, transposition easy operation, the design of door arch support makes the contrast operation between the demonstration board more nimble, various moreover, better the interference of non-contrast tense of having avoided, makes learner's energy concentrate more, and the demonstration effect is better, improves learning efficiency.
