Do you have a ver y strict teacher ? I do. He is Mr. Grand , our geography teacher. We call him “Mr. Grumpy” because he often gets angry ( 生气的 ) . Not finish your geography homework ? Good luck to you. Mr. Grumpy will give you a good lesson . “Rules , rule s , ”the old man always says. No students can be late for class. Everyone must keep quiet in his class , and finish homework after class. And no one can ask for leave( 请假 ) on test day. Many of us are a fraid of Mr. Grand. But he is very happy. Sometimes he buys us sweets ( 糖果 ) . We think he is lovely only that time.
