      There are many different ways of seeing a town for the first time. One of them is to walk around it,
guide-book in hand. Of course, we may    1    with our guide-books the history and special developments
of a town and get to know them.    2    then, if we take our time and stay in a town for a while, we may
get to know it better. When we look at it as a whole, we begin to have some    3   , which even the best
guide-books do not answer. Why is the town just    4   this, this shape, this plan, this size? Why do its
streets    5   in this particular way, and not in any other way?
      Here even the best guide-book fails us. One can't find in it the information about how a town has
developed to the    6   appearance. It may not describe the original (最初的) design of a town. However,
one may get some ideas of what it    7   to look like by walking around the town. One can also imagine 
   8    the town was first planned and built. Then one can learn more about in what direction the town    9   
to develop.
     What is the point of studying towns in this way? For me, it is simply that one gets greater pleasure by
visiting and seeing a town with one's own eyes. A personal visit to a town may help one better understand
why it is attractive   10  just reading about it in a guide-book.
