There are many different ways of seeing a town for the first time. One of them is to walk around it, guide-book   36  hand. Of course, we may   37  with our guide-books the history and   38  developments of a town and get to know them.   39  then, if we take out time and  40  in a town for a while, we may get to know it better. When we   41  it as a whole, we begin to have some   42  ,which even the best guide-books do not answer. Why is the town just  43  this, this shape, this plan, this size? Why do its streets   44   in this particular way, and not in any   45  way?
Here even the best guide-book   46  us. One can’t find in it the information about how a town has developed to the   47  appearance. It may not describe the original (最初的)   48  of a town. However, one may get some idea of what it   49  look like by walking around the town. One can also imagine   50  the town was first planned and built . Then one can learn more about in what direction the town   51  to develop.
What is the   52  of studying towns in the way? For me, it is   53  that one gets a greater depth of pleasure by visiting and seeing a town with one’s own eyes. A   54  visit to a town may help one better understand why it is attractive   55  just reading about it in a guide-book.
