The school rules were very strict as well as the teachers. Students (share)their ideas freely, they (speak)only when they were allowed to. In the morning, before class teachers (check)students’ nails, hair and teeth to make sure they were clean. They sometimes (shout)at students or even (give)a smack with a ruler or cane on their hands!
