Passage C

Should we allow modern buildings to be built next to older buildings in a historic area of a city? In order to answer this question，we must first examine whether people really want to preserve the historic feel of an area. Not all historical buildings are attractive. However, there may be other reasons-for example, economic (经济的) reasons-why they should be preserved. So, let us assume that historical buildings are both attractive and important to the majority of people. What should we do then if a new building is needed?

In my view, new architectural styles can exist perfectly well alongside an older style. Indeed, there are many examples in my own home town of Tours where modern designs have been placed very successfully next to old buildings. As long as the building in question is pleasing and does not dominate(影响) its surroundings too much，it often improves the attractiveness of the area.

It is true that there are examples of new buildings which have spoilt(破坏) the area they are in，but the same can be said of some old buildings too. Yet people still speak against new buildings in historic areas. I think this is simply because people are naturally conservative(保守的) and do not like change.

Although we have to respect people's feelings as fellow users of the buildings, I believe that it is the duty of the architect and planner to move_things_forward. If we always reproduced what was there before, we would all still be living in caves. Thus, I would argue against copying previous architectural styles and choose something fresh and different, even though that might be the more risky choice.
