こんばんは。 
I can’t come to school this Wednesday(5/7) and next Wednesday(5/14) because of my job.
So please review all the materials I gave you and practice hiragana this week.
I think it’s time to memorize hiragana… I suggest you to memorize hiragana with words. Please use your workbook and the vocabulary lists on handouts.
If you have questions, please ask me on Friday(5/9).
I’ll check you on Fri if you remember what you’ve learned recently…

Study hard おねがいします.
おやすみなさい。
