Today, when I walk on the street after school, I find the street is very clean, it is very different from usual days. I am so curious¹, so I ask the cleaner, she tells me that many students have behaved, they don’t throw away the rubbish anymore. I think about the education about the environment last week, it works². We should protect the environment.

今天，当我放学回家走在路上的时候，我发现街道很干净，和往日很不一样。我非常好奇，因此问了下清洁工，她告诉我很多学生已经自律了，他们不再随处扔垃圾。我想起了上周关于环境的教育，确实起作用了。我们应该保护环境。
