The purpose of this study is to investigate the educational appropriateness of the interpretation and application of present sentence patterns and to explore the direction of the teaching and learning principles in the future. The conclusions of this study are as follows. (1) When the connecting endings, which is a learning sentence type, connects the preceding and succeeding sentences by antecedent clause and following clause, it should be judged as the sum of the connected whole situations, not to be understood in combination with the combination condition of the leading or the succeeding sentence after the primary interpretation and application of the learning sentence. Therefore, it is not educationally useful to classify and organize sentence patterns similar to the learning sentence patterns themselves. (2) Learning sentence patterns should be interpreted numerically, according to the conditions, and it is important to grasp the premises correctly at this time. Therefore, it should be possible to focus on education in consideration of everything that can be classified as a condition to be combined.
