Students look at the pictures and write. Please keep quiet.

At noon on Tuesday, Xiao Ming came to the library and borrowed a "joke" from the lending office. When he saw interesting places while walking, he couldn't help laughing. At this time, the librarian aunt pointed to the big word "quiet" on the wall and whispered, "Children, keep quiet in the library." Xiao Ming listened and thought, yes, I will disturb others' reading if I laugh loudly. So he hurried outside the library and read with relish.
