Mr. Green is a very good teacher. He is both kind and strict with his students. But he can't bear laziness. His students must study very hard. He asks them to speak English in his class, and they have to learn to write in English, too. Mr. Green thinks the students should use English as much as possible, because English is important for their future jobs. Mr. Green also spends a lot of time with the students out of class. During his office hour, Mr. Green helps the students with their questions. The students can also play word games with Mr. Green and sometimes they learn to put on an English play. The students enjoy the office hour. They really learn a lot from Mr. Green. Now it's Mr. Green's office hour again.
