寫作思路：
1.首先確定這是一篇描述地方的說明文.
2.確定寫作要點(diǎn)：根據(jù)所給信息,大體可以分為三個(gè)部分——城市簡介,可以按照地理位置、自然環(huán)境、城市面貌和變化發(fā)展這樣的邏輯順序?qū)?接下來寫你看到的問題,最后寫你的一些看法和建議.
3.各層次之間注意使用恰當(dāng)?shù)倪B詞,讓過渡自然,結(jié)構(gòu)合理.比如：however,in my opinion 等.
Dear Bob,
It’s very kind of you to write me and let me know about our beautiful city.Now I’d like to tell you something about my hometown Jiangcheng.
The city stands on the bank of the Changjiang river.It is a beautiful place for people to live in.Its economy has been developing rapidly in the past ten years.New factories,houses,and roads have been built.More schools and hospitals are available for its people.However,there are still some problems,such as water and air pollution and heavy traffic in rush hours.In my opinion,Jiangcheng should develop its economy scientifically.I would also think that the growth of its population should be brought under control so that we’ll have a better hometown in future.
Yours,
Xiaohua
