I have never understood the importance of parties in the classroom. As a mother of two school age children, I believe that public schools should no longer  41         classroom parties during the school day.

 42          is very important to students in school today. Our school year is already too short. Teachers can only just get all the basics of the courses (课程) into the  43          instructional minutes of the day.  44         , there is no time for anything useless or silly.  45          time is best spent focusing on the primary goal — learning.

And what about food? For health and safety reasons, schools often require that  46          for these activities should be bought from a store. This  47          a real problem for many families. Biscuits for a class of students, plus drinks and napkins can  48  what it costs a family to eat a meal at home. The  49          of a classroom party is  50          a problem for many people, especially in these difficult times.  51         , we all know that our children have eaten enough sugar and junk food without the school  52          such unhealthy choices.

All the  53          that a party can create is unacceptable! I  54          those birthday parties held at home for my children. I would just buy the disposable (一次性的) plates, cups, and napkins  55          I didn’t need to do any cleaning up. But even so, I just  56          to fit all the party time rubbish into the rubbish bin (垃圾桶).  57          the trash thrown out by a school of 16 classrooms and over 400 students. It only adds to the  58  of our planet’s environment.

I am not sure when our public schools decided that classroom  59          needed to become a part of the school calendar (日历), but I do not see the  60         . So I do believe schools should forbid (禁止) classroom celebrations.
