完形填空。
     Recently I paid a visit to Harvard University, where there are top class scientists and professors and the
best academic system in the world.
     I was very   1   when I first stepped onto the campus (校园). Well, it's not even really a campus. It's   2 
 like an area in a small town.
     Harvard's main buildings are from the 18th century. They look very old and   3  . You might   4   say they're
a little shabby (破旧). They don't fit the modern   5   of university at all. The buildings are surrounded by   6   
and trees, so I felt as if I had walked into a castle of the Mid-Ages. But when I looked across the street, the   7 
 shops and in-fashion (时尚的) students made me feel like I was in the 21st century    8  . It creates a strong
contrast (对比) and brings a special   9   to the school.
      Our tour  10   Gary took us around and told us."You see this grass field in the center of the school? Here is
where they hold their   11   ceremony. They just set up tents and benches and have a very simple ceremony."
It's  12   ! Who would think the most talented students just graduate on the grass?
      I   13   some students put a blanket on the grass and lie down to read a book. When I listened to the soft
sound of  14  turning, along with the singing of the birds, I felt very   15   . There was no competitive feeling
at all.
     Harvard has the world's first computer in its science centre   16   there are hundreds of high-end computers,
too. Its religion(宗教) and the literature departments are also   17   the best. It is the perfect mix of tradition an
  18   technology. It makes Harvard a very attractive place to  19  in.
      I hope one day I'll   20   my dream school-Harvard.
