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 visions are covered. What’s more, there are so many factories setting 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.

　　【參考譯文】

　　在中國有一句古老的諺語——月是故鄉(xiāng)圓。每次回到家鄉(xiāng)時，我都會想起這句話。事實上，家鄉(xiāng)的'月亮更皎潔，也更圓。最主要的原因是天空污染沒那么嚴重，所以我可以看到藍色的天空。與城市的不同，那里建筑物高，人們的視線也就被擋住。而且，還有很多工廠釋放的氣體污染了空氣。我在城里的時候，就會想念我的家鄉(xiāng)，不僅是秀麗的風景還有皎潔的月亮。
