写作思路：开篇表明随着时间流逝，家乡发生了改变。然后对过去的家乡做介绍；接下来对家乡的现在风貌做介绍，最后总结。
示例如下：
As time goes by, many things have been changed in hometown. Let me tell you something about them.
In the past, my hometown was not so good. For one thing, the roads were so old that it’s difficult for people to walk or drive on.
Also, there were few cars and people on the roads. For another, the environment was polluted seriously. It seems that my hometown was poor.
Now, with the development of the society, roads are wider and newer than before. Also, the environment has been improved.
Therefore, the air is fresher, the sky is bluer and plants are greener. Moreover, there are not only many places of interest like Dream Valley and Qin Palace and so on, but also different kinds of delicious food.
In a word, my hometown is well worth visiting. I am proud of it and I hope it will be better and better.
【翻译】
随着时间的流逝，家乡发生了许多变化。让我告诉你一些关于他们的事。
过去，我的家乡不太好。一方面，道路太旧了，人们很难走路或开车。此外，道路上几乎没有汽车和人。另一方面，环境受到严重污染。看来我的家乡很穷。
现在，随着社会的发展，道路比以前更宽和更新。此外，环境也得到了改善。因此，空气更新鲜，天空更蓝，植物更绿色。而且，不仅有梦幻谷和秦宫等名胜古迹，而且还有各种美味佳肴。
总之，我的家乡值得一游。我为此感到自豪，并希望它会越来越好。
