完形填空。 The half-empty coffee cups, still

     The half-empty coffee cups, still standing next to their plates, tell of a morning like any other. And
yet, that grey covering of dust that everything   1   tells a different story: it tells of screams, tears, terror
and   2  . Now the restaurant in the World Trade Center will   3   again serve breakfast. And never
again will all those people go there to eat or   4  . So many people whose faces we associate with life
and liveliness are gone
   5 . So many words remain    6  , and so much happiness has been destroyed. In their places are
tear-stained(泪水沾湿的) faces.
     My generation has seen this. On Monday, a fight with my sister, a bad grade and homework 7  to
be the biggest problems in the world. Tonight, so many across the country know that America's pain
is at its    8   ever.
     We have   9   World WarⅡ. But to most of us students, that's an event on a textbook  10   that
would never happen today.  
     After all, this was a time of   11   and wealth-the United States was powerful and successful. There
would be no more wars, and we were   12   to live in such a time.
     But when those planes   13   ; when firefighters with   14   on their faces ran among the parts of the
building that had fallen; when people   15   for their family members; when history was unfolding before
our eyes, in full, clear color-then we knew the world had been changed.   16   how many human beings
turned to ashes in a second, and seeing some jump from the buildings, I know that my generation is
growing up in a world where    17   can still be evil.
     But seeing those heroes risk their lives among the castle-like ruins, and seeing the   18     blood
donors at the hospitals, my generation has learned that tears are allowed, that mankind can also be 
  19   , and that the ghost of evil never   20   the spirit of good.
