观点类大作文，城市规划类话题
In the past, buildings often reflected the culture of a society but today all modern buildings look alike and cities throughout the world are becoming more and more similar. What do you think is the reason for this, and is it a good thing or a bad thing?

1、题目大意
过去，建筑通常反映了一个社会的文化，但是现在的建筑看上去都差不多并且城市也变得越来越相似。原因是什么?利弊如何？
2、思路解析
这是一道混合类大作文，讨论的是城市和建筑趋同的原因和利弊。报告类的题型的结构比较简单，两个主体段分别对应两个问题，主体段一回答原因，主体段二讨论利弊。审题时候需要注意一点，过去与现在的对比。下面，月半鸭和大家一起来看下具体观点。
首先是分析原因。
过往建筑风格差别很大，可能是多种因素造成的，比如运输条件、气候环境、工艺交流等。受限于运输限制，不同地区的建筑在建造过程中往往只能就近取材，因此在各地能看到以竹、木、土砖等为主体的不同建筑物。同时，不同地区的建筑也会将当地气候的应对问题考虑进去，比如热带地区会更注重潮湿的问题，而寒带地区则会优先考虑防寒防冻。在各种因素条件下，各地也形成具有当地特色的建筑。
而如今，建筑风格趋同，一定程度上是由于建筑工艺技术的发展，以及各地的交流日益紧密。新型的建筑材料比如混凝土由于更加耐用、便于生产、适用性广，因此在各个地区都被广泛使用，使得各地建筑很难再看到当地特有的材料。同时各地建筑师紧密交流，也会相互借鉴和模仿，慢慢使得建筑风格开始趋同。
对于城市而言，由于大量人口有的涌入，城市发展也更加追求高效和实用。为了满足大量人口居住，原有的矮楼开始被相似的高楼所替代。商业区、办公楼等场所也会出现在每一座城市，这使得大家觉得城市开始变得一样。
利弊角度来说。
坏处在于，特色建筑的消失对于当地的文化传承是一种损失，缺乏多样性的建筑风格也不利于未来持续的设计创新和体现不同城市的独有魅力。
好处则是，由于目前的建筑可复制性高，实用性更强，建造成本和设计成本更加低廉，在城市的不断扩张过程中便于大规模的使用，以满足人们日益增长的居住需求。
3、提纲
4、高分范文示例
In contemporary society, there has been an increasing trend for modern architecture to resemble one another. In this short essay, I will delve into some reasons for this phenomenon and present both positive and negative impacts.
The fundamental reason for this is that the breakthrough in communicating technology has prompted the occurrence of this situation. In ancient times, every civilization has developed their own style of buildings, for example, Byzantine, Gothic, and oriental styles. However, the transportation technology at that age is not capable of transporting architects and designers to remote areas to mimic different styles. In today’s society, yet, thanks to effective communication, such as flight, shipping, etc., architects are easily accessible to other existing models of buildings, and therefore, it is no surprise for imitation to be found on a large scale, which makes modern buildings today monotonous. Besides, from an urbanization perspective, a large number of immigrants flock into major cities, which leads to an unavoidable outcome that flats and bungalows cannot accommodate those comers, so the high rise buildings have replaced the traditional ones. With time passing by, the steel jungle has gradually become the modern style of a city.
It is not certain whether this situation will affect our society positively or negatively. On the one hand, its economic merits are obvious. With more architectural references and more efficient network, the costs of designing a modern high-rise building are lower than before, which save the expense of design. On the other hand, this situation will also exert a devastating impact on architectural culture if it goes too far. In addition, it goes without saying that innovation plays a crucial role in almost every aspect of human civilization, and its absence would be catastrophic.
As conclusion, while similarity among modern architecture can bring about economic benefits, the diversity should not be ignored.
