In this paper, the misuse that occurs when the predicate and others preceding the pattern expression is followed by the pattern expression (‘case-marking postpositional particle ni+verb’, etc.) is examined by JLPT level of learners.
The percentage of correct answers by learner’s JLPT level was higher in the order of N1, N2, and N3 learners in all 48 questions or 5 types. However, it was found that 16 of the 48 questions (33.3%) was not. Furthermore, the percentage of correct answers for N1 learners were 53.4%, and the percentage of correct answers for all learners(N1+N2+N3) was only 37.5%. Accordingly, it was found that it was difficult to acquire connective postpositions of Japanese pattern expression.
And the following are typical types of misuse of connective postpositions of Japanese pattern expression(‘case-marking postpositional particle ni+verb’, etc.): ① elimination of the postpositional particle ni, ②③ confusion of verbs and nouns that precede the postpositional particle ni, ④ Addition of the formal noun, no and koto. The higher the JLPT level, the lower the percentage of wrong answers in ①, ②(Verb misuse) and the higher the percentage of wrong answers in ④. The percentage of wrong answers in ③ is not constant (N1> N3> N2 learners).本稿では、表現文型(「格助詞ニ+動詞」など)に前接する用言などが、それらの表現文型と接続するときに発生する誤用について、学習者のJLPT水準別に考察した。 学習者のJLPT水準別の正答率は48問題全体や5つの類型別ではN1、N2、N3学習者の順で高いが、48問題それぞれにおいては16問(33.3%)はそうではないことが分かる。また、N1学習者の正答率が53.4%であり、学習者全体(N1+N2+N3)の正答率も37.5%に過ぎず、表現文型の接続の習得が困難であることがよく分かる。表現文型(「格助詞ニ+動詞」など)の接続の誤用の類型は、[A]格助詞ニの脱落、[B][C]格助詞ニに前接する動詞・名詞の混同、[D]形式名詞ノ・コトの添加などが代表的である。JLPTの水準が高いほど[A]、[B](動詞の誤用)は誤答率が低く、[D]は高い。[C](名詞の誤用)は一定していない(N1>N3>N2学習者)。
