I think it is necessary to protect the environment, because it is good for everyone so my class has chosen the job of cleaning the classroom. On the Friday afternoon, my class started. To do well in class, I prepared a mask, mop, broom .... The teacher assigned tasks to each team, each of you was very detailed. The male friends are strong so the teacher is assigned the task of preparing tables and chairs, sweeping the web. And the girls do the job of picking up rubbish and cleaning boards. I was assigned by the teacher to wipe the board. I first rubbed a towel and went back to class to wipe the board. I wipe from one board to another to keep it clean. The working day was very tired but it was fun, I looked at all the faces of my friends being red, sweating profusely. When the headmistress entered my class, I praised the teacher so that everyone in the class was rewarded. Less than an hour of class I finished. I am very proud of my class.
