作文主题：The bar chart shows the distribution of employment among agriculture， services， industries in three countries in 1980 and projected distribution in 2020.
In some cities， there are few controls over the design and construction of new homes and office buildings， so people can build in whatever style they like. Do you think advantages outweigh disadvantages ？
Since diversity has arisen a fierce discussion among the group who wants to be different from others， and the distinctive aesthetics is being chased by more people， especially in some modern metropolises， which is reflected in the design of most building. I believe this can bring both benefits and drawbacks to the development of the cities.
The freedom of selecting the styles could make the society more diverse， which can embrace a variety of artists to come in and decorate the city with their talents； such phenomenon would be an effective way to promote the development of local culture and stimulate the competition between different artistic groups to inspire a more prospective cultural atmosphere. Besides， conducting the certain style in our buildings can be regarded as a release of our nature and personalities， about which most young people care in the modern world. And no one can deny that the sense of satisfaction brought by living in the building with our preference would not be replaced by other things.
However， the disadvantages in the society are looming. Nowadays， the city planners pursue a unified style in constructing an area， and the top concern for them is whether the new buildings could fit in the old ones， which might make the city look better in general， but contradicts the thoughts of former group mentioned. In addition， if a great number of styles were applied， it would have been harder and increased the cost for the later work of protection and maintenance.
In conclusion， what kind of styles people choose has both advantages and disadvantages， and the government should take different views into consideration， because to make our city better is the mutual purpose； to a certain extent， it can bring positive and unexpected results to give residents some freedom to meet their demands.
