此文立意很深刻,不止于要破除思维定势。还提出“破除思维定势”的措施。这一措施的提法十分新颖——“把自由还给鸟笼”。但是,第四至五自然段所用材料不新颖;即使只能引用这些“老资格”的材料来阐述观点,也要选定一个特定的角度——让其做出“新贡献”! This article is very profound, and it is not only necessary to break the mindset. It also proposed measures to “break the mindset”. The formulation of this measure is very novel - “returning freedom to the bird cage.” However, the materials used in the fourth to fifth paragraphs are not new; even if they can only use these “qualified” materials to explain their viewpoints, they should also choose a specific perspective—letting them make “new contributions”!
