Today's Lesson Vol.36

Last week, Serizawa Keisuke Art Museum generously donated books to the Shizuoka Taisei library. The books are now displayed in a case at the front of the library. Thank you very much.

Summer holidays finished last week and the Taisei students are now back at school. The students looked like they had enjoyed their summer holidays. But, everyone is now very busy.
Second semester is long, but has several exciting events, such as the school speech contest which takes place this week, next week and the week after.

Complete this idiom that means to be very busy.
