There is an old Chinese saying that the moon in the hometown is full. Everytime when I go back to my hometown, I will think of this saying. Indeed, the moon in my hometown is much clear and bigger. The most important factor is that the sky is not polluted seriously, so I can see the blue sky. Unlike in the cities, the buildings are tall and people’s visions¹ are covered. What’s more, there are so many factories setting² out the gas that pollutes the air. When I stay in the city, I will miss my hometown, not noly the beautiful scenery, but also the clean moon.

在中国有一句古老的谚语——月是故乡圆。每次回到家乡时，我都会想起这句话。事实上，家乡的月亮更皎洁，也更圆。最主要的原因是天空污染没那么严重，所以我可以看到蓝色的天空。与城市的不同，那里建筑物高，人们的视线也就被挡住。而且，还有很多工厂释放的气体污染了空气。我在城里的时候，就会想念我的家乡，不仅是秀丽的风景还有皎洁的月亮。
