「~ておきます」是初級的文法項目,例如在『大家的日本語』裡,初級後半第三十課提出了「準備」、「措置」、「放置」的用法。但對學習者而言,很難分辨有「~ておきます」與沒有的差異,或是很難分辨「準備」和「措置」的差別在哪裡等等,有許多學習者感到困惑的項目。本稿以對學習者而言容易理解的記述和教學方法為目標,提出「~ておきます」的基本用法為「措置」,使用在「為了避免發生問題而做的準備」的場面、文脈之指導案。|This paper proposes a method for teaching -te okimasu. This is regarded as a grammatical item that the beginner-level learners learn. For example, "Minna no Nihongo", a textbook for elementary level, presents -te okimasu as the expression which has thee usages : a necessary action or behavior to be performed by a certain time, preparation for something in the future (called "preparation"), some temporary measures or completing a necessary action in preparation for the next time one use something (called "measures"), keeping a resultant state as it is (called "keeping"). However, -te okimasu has a lot of problems for learners, for example, the difference of presence or absence of -te okimasu is not clear, it is hard to distinguish which usage is , etc. Therefore, in this paper, aiming for the description and the teaching method that are easy to understand for learners, we propose a method for teaching : -te okimasu is to be considered as "measures", and used in the situation that " to take measures so that problem will not happen".|This paper proposes a method for teaching -te okimasu.
