explanation: "environmental protection" refers to the general term for various actions taken by human beings to solve environmental problems, and "energy saving" is an "environmental protection" action. "rotten" refers to depraved behavior, especially the use of power for personal gain, embezzlement and bribery, corruption of life, etc. by state functionaries. "corruption" belongs to "rotten". the intrinsic value of "culture" is "civilization", and the external form of "civilization" is "culture". "autumn" is a season, and "solar terms" refer to the 24 specific seasons in the solar calendar (dry and branch calendar) that represent seasonal changes. there is no obvious logical relationship between "autumn" and "solar terms". "leisure" can modify "sports" into the phrase leisure sports.
