My mistake!!!

This day at my english class. First, we learned "Save the world" ,and we learned with new teacher. She smile all the time and have a humour. When my friends came in class but no one sit in front of, and she said "Sit here , I'm not a monster.". She was came from China, and very active while taught. Since she tell us "This is my first class". End of the class, we take photos with her before she come back to her country. Next, my group present with "Conjunction". When I stood in front of class, I feel very excited. I will apologize everyone . Because my group chose exercise from internet and this excercise cause of quize. Finally, we have quize from my exercise.
