                          Organizing your household garbage

Dear foreign friends, glad to meet you here. Today I'd like to introduce new garbage sorting rules to you. In Shanghai, we are supposed to 1. the garbage into four groups, namely recyclable, harmful, dry and wet waste.  Paper, plastic, glass, and fabrics is 2. waste while food leftovers, plants, expired food is wet waste. Batteries, light tubes and 3. should be considered to be harmful waste. All other non-recyclable solid waste is called dry waste. We all believe that garbage sorting is 4. for the protection of the environment. Right? If people fail to sort their garbage, they will be fined up to 200 yuan. If all of us take pains to sort garbage, we'll lead a better life. So, let’s start right now.

Give the foreign students a piece of advice about garbage sorting.
