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.
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。
