Description
Technical field
The utility model is related to middle school Chinese language teaching aid field, and specifically a kind of head extracts practice teaching aid.
Background technology
In the teaching of middle school's Chinese language, the initiation of Chinese language grammer is the important step of study.During sentence is constituted, respectively
Plant the role of sentence element not exclusively the same, the trunk of so-called sentence refers to the attribute in sentence, the adverbial modifier, complement (i.e.
" branches and leaves " composition) layer-by-layer contraction fall after remaining part.The trunk of sentence be usually by subject or subject head, predicate or
What predicate head and object or object head were constituted.It is Chinese language grammar learning for the extraction and analysis of sentence trunk
Important content, determines that language reads the height for understanding and writing a composition ability to express, the emphasis do not imparted knowledge to students still is also examination
Emphasis.
Because the change of Chinese clause is enriched, in order to grasp the understanding to sentence center implication, need to do big on classroom
The example sentence of amount divides explanation and practised (typically using following division symbol：Subject "-", which is divided, with "=" divides predicate use
" ﹏ " mark object marked with " () " attribute marked with " [] " adverbial modifier with "<>" mark complement).This generally requires teacher's writing on the blackboard and shown
Example is completed, and not only influences classroom to give lessons efficiency, and brings heavy burden to teacher.But if thrown using projecting apparatus
Shadow, then can not be divided and be marked to projection sentence, i.e., the explanation of inconvenient teacher is also unfavorable for the understanding of student, and class
Hall interaction effect extreme difference.Example sentence exercise can either quickly be shown by needing one kind on existing classroom badly, and the head of convenient mark is carried again
Take practice teaching aid.
Utility model content
The purpose of this utility model is that providing a kind of head extracts practice teaching aid, and it directly can show and be switched fast
The example sentence and exercise set, and convenient progress division mark, facilitate teacher to explain, and the displaying to knowledge point is more directly perceived, raw
It is dynamic, the interaction effect in classroom is drastically increased, student's fast understanding and grasp is helped.
The utility model to achieve the above object, is achieved through the following technical solutions：
