The school literature club has launched a series of Chinese activities with the theme of "I am a hero of idioms". Now is the time.

(1) Example: Chinese is extensive and profound, and the idiom drops of water hide the sea (2) Example: Hello, uncle! Idiom is a national language and culture, which can't be tampered with at will, otherwise it will bring bad influence to teenagers in school and endanger Chinese education. Moreover, after the tampered idioms are deeply rooted in people's hearts, they lose their original meaning, which is a disrespect for China's language and culture. (3)① Put "understanding" before "application". (2) improvement. Or: change the method to the ability. 3 You can change getting twice the result with half the effort to getting twice the result with half the effort.
