1. When answering this question, you can compare the environmental conditions of the city and the countryside. Generally, cities are considered to be dirtier due to higher population density, industrial activities, and traffic, which contribute to pollution and waste. 2. On the other hand, the countryside is often perceived as cleaner due to fewer people, less industrial activity, and more natural surroundings. However, it's important to acknowledge that this can vary depending on the specific city or countryside area and the environmental policies in place. You can also discuss factors like waste management systems, green spaces, and public awareness about cleanliness in both settings.

1. 在回答这个问题时，您可以比较城市和农村的环境条件。一般来说，由于人口密度较高、工业活动和交通等因素导致的污染和废物，城市被认为更脏。 2. 另一方面，由于人口较少、工业活动较少以及自然环境更多，农村往往被认为更清洁。然而，重要的是要意识到这可能会因具体的城市或农村地区以及所实施的环境政策而有所不同。您还可以讨论垃圾处理系统、绿化空间以及公众对两种环境中清洁问题的认知等因素。
