“Bayview High School is considering whether to require all of its students to wear uniforms while at school. Students attending Acorn Valley Academy, a private school in town, earn higher grades on average than Bayview students and are more likely to go on to college. Moreover, Acorn Valley reports few instances of tardiness, absenteeism, or discipline problems. Since Acorn Valley requires its students to wear uniforms, Bayview High School would do well to follow suit and require its students to wear uniforms as well.” 111. 给地方报纸的编辑的一封信: Bayview高中正考虑是不是要要求它的学生在校时都穿制服。Acorn Valley Academy,本镇的一所私立学校的学生比Bayview的学生的平均成绩要高,也更容易上大学。而且,AV基本上没有迟到(tardiness)旷课和纪律问题。由于AV要求学生穿制服,Bayview高中跟着做并且也要求学生穿制服将得到很好的效果。 111. 给地方报纸的编辑的一封信: Bayview高中正考虑是不是要要求它的学生在校时都穿制服。Acorn Valley Academy,本镇的一所私立学校的学生比Bayview的学生的平均成绩要高,也更容易上大学。而且,AV基本上没有迟到(tardiness)旷课和纪律问题。由于AV要求学生穿制服,Bayview高中跟着做并且也要求学生穿制服将得到很好的效果。
