我是班级里的科学课代表。别看我可以天天在教室里快乐地做实验,可是我的烦恼也不少。因为科学书是循环教材,所以每当上课之前,我都要去其他班级拿书。拿书是没问题,可找书却成了大问题。我要一个班一个班找过去,一楼没有跑二楼,二楼没有上三楼,找不到书分发迟了还要被批评,真烦恼呀! I am a class representative of science class. Do not look at every day I can experiment happily in the classroom, but I have a lot of trouble. Because the science book is a cycle of textbooks, so whenever class, I have to go to other classes books. There is no problem with books, but finding a book is a big problem. I want a class to find a class in the past, the first floor did not run the second floor, the second floor did not on the third floor, can not find the book distribution late have to be criticized, really annoying ah!
