Dear Jim,
亲爱的吉姆：
You want to learn the changes about my hometown. You know, great changes have taken place since 70 years ago.
你想知道我家乡的变化。你知道，在过去的70年，这里发生了翻天覆地的变化。
In the past,most people had a very poor lifestyle.Very few people had comfortable homes,convenient transportation,or even enough food to eat. Homes were shabby,there were few vehicles and roads were narrow.Communication was very difficult and slow.
过去，大多数人生活贫苦。极少人有舒适的住房、便捷的交通工具，甚至吃得饱饭。房屋破旧不堪，几乎没有车辆，道路很狭窄。通讯非常困难和缓慢。
今天，当我们环顾四周，看到人们享受着这样现代化的舒适生活时，我们真的感谢政府的政策带来了这些变化。如今，到处可以看到人们开着车，用手机聊天，住着漂亮的房子。我坚信我们的生活水平会继续提高。
When we look around today and see people enjoying such a modern and comfortable lifestyle,we really appreciate the government’s policies that created these changes.Now it is common to see people driving cars,chatting on mobile phones and living in beautiful homes.I really do believe that our lives will keep on improving.
Sincerely,
Jiajia
此致敬礼
