Should a city try to preserve its old, historic buildings or destroy them and replace them with modern buildings? Use specific reasons and examples to support your opinion.
It is a controversial problem that whether a city should preserve its old, historic buildings or destroy them and replace them with modern buildings. Some people think that a city should preserve its old, historic buildings because they are the witness of the past, others think that a city should destroy them and replace them with modern buildings because they take up a lot of places. As far as I am concerned, I prefer the previous idea that the old, historic buildings should be preserved.
Although the old, historic buildings would take up a lot of places and the modern society will need these places to building the new buildings such as skyscrapers, the old, historic buildings are the witness of the history. It is known that a modern city comes from the past history, which had a valuable experience. The old, historic buildings could tell people what happened in the past and what was the past like. From that, people could gain knowledge and experience to contribute to the modern society better.
The old, historic buildings could also be offered to education. They can become the teaching bases for children. It is necessary for children to know the past, so that they can know better about the present society. In addition, children will be interested in the strange structure of the buildings and the funny things in the buildings, which will promote the children to study.
Finally, the preserved building would offer the important clues for archeologists to study the past. It is more valuable to maintain them well than destroy them to build new ones.
In conclusion, the old, historic buildings should be preserved for the reasons above. First is that they are the witness of the past, then they could teach children something and last they are the important clues for archeologists.
满分要素剖析：
一、 语言表达
本文语言用词地道多样，在句式上采用了很多固定句型，主语从句也占有一定数量，长句难句让文章表意流畅，不会被过多的简单句打断思路，也不会有重复的感觉。
1. It is a controversial problem that whether a city should preserve its old, historic buildings or destroy them and replace them with modern buildings. 这是主语从句中用it 作形式主语的结构，这种结构在文中多次出现，比如it is known that... 避免了主语过长而造成的头重脚轻。
2. It is more valuable to maintain them well than destroy them to build new ones. 本句中有more than句型的灵活运用，也是因为主语过长而用it做形式主语的例子。
3. First is that they are the witness of the past, then they could teach children something and last they are the important clues for archeologists. 首先，作为一个概括总结句，句中少不了串联连接词first、then和last，然后此句中两个比较好的表达：witness of the past和 clues for archeologists中witness和clue都是比较地道的用法，可以学习。
二、 逻辑结构
本文是从正面来具体论证自己的观点，从三个方面来说明古建筑的不可抹灭，在展开论述之前，也有先做让步来引导出第一个分论点，既作为过渡的手法，也考虑了逻辑的全面性。但正面论点和论述都稍有重复，略显单薄。
在结构方面，整个文章是采用总分总的结构，文章用标准的议论文三句话开头：摆背景，列争论，亮观点，结尾全面地总结和重现全文的论点及分论点，是比较固定稳重的架构。
