3 2011年1月底，杭州市卫生局下发了关于加强中药饮片处方管理的通知，对于治疗常见病、多发病的方剂，要求每帖用药控制在18味以内、价格控制在40元以内，目的是要减轻老百姓的看病负担。杭州某中学高三（4）班同学就政府这一行为展开了激烈的争论，形成两组截然不同的观点，一组同学认为，政府“限价令”一出台，某些中药价格应声而落，这才是地方政府的应有作为。另一组同学则认为，“限价令”保护了市民却伤了药商。谁替药商着想？看看价格日益飞涨的运费，看看打着滚往上翻的种药成本，中药价格能不涨吗？选择一组同学的观点运用经济生活知识简要说明理由。 ____________________________________________________________________________________________________________________
