19-1. Conjugation Practice
The AI robot that you are helping learn Japanese wants to learn how to speak casually. Help the robot by recording the given words in the right short forms.
Common Characteristics: ない, た (or だ), なかった
First, help the robot learn Japanese the common characteristics of short forms across all parts of speech — ない, た (or だ), and なかった — by recording the given words in the right forms.
U-verb Non-past Negative Forms
The robot has understood the general concept (ない, た, and なかった), but needs more data to master u-verb conjugations. As the second step, record the non-past negative forms of u-verbs.
U-verb Past Affirmative Forms
Finally, the robot is tackling the past affirmative forms of u-verbs. First, sing the mnemonic song below to confirm the conjugation patterns of ru-verbs, irregular verbs, だ, i-adjectives, and negative forms.
Next, sing the mnemonic song for u-verbs.
For the final step, record the right u-verb past affirmative forms for the given words.
