We went to Mochou Lake last year. The lake was messy and dirty. What made the lake messy? There were a lot of plastic bags, cans and lunch boxes. There were some broken bottles too. The pollution（污染）was serious. To keep the lake clean, we should put rubbish in the bin and put a sign “No littering”near the lake. We shouldn't litter anywhere. Everyone should know this and protect （保护）the lake. This year,Mochou Lake becomes more beautiful. We are happy to see that.
