改变我的家乡为何先选环境？ 我的家乡是个人口密集的大城市。

My hometown is a large city with a dense population.

如果我只能改变家乡的一样东西，那么我想改变的就是它的环境。

If I could change just one thing about my hometown, it would be the environment.

是的， 凡是它能给予我的别的城市也可以给与，但实我的爱将永不被改变。 因为，这里才是我的家乡。

Yes, everything that it gave me could be given by other places, but my love won't be changed, because it is my home town.
