完形填空。
     This year 1 the 100th anniversary of the sinking of the Titanic. Like some American 2 in the 2008
financial crisis, the ship was thought to be "too big to 3 ". But the banks failed and the Titanic failed..
.spectacularly! After hitting an iceberg, it plunged to the bottom of the 4 Ocean. In less than three hours,
the "unsinkable" ship was just a wreck and over1,500 people were dead.
     Most of us know the story of the Titanic from watching the James Cameron film. It's now been released
in a 3D version and new audiences can see the tragic event  5  and be moved by the love story of the two
main characters, Jack and Rose. But Titanic is   6 a love story; it's the story of   7 ordinary people react
when faced with   8  circumstances.
     In 1852, the HMS Birkenhead foundered on rocks near the coast of South Africa. The British ship
was carrying soldiers, and also many women and children. There weren't enough 9 for everyone so the
order was given, "women and children first."  10 the women and children were being saved, the soldiers
stood at attention on deck and,   11  , went down with the ship. They faced their death with bravery and 
  12 .
     The  13  , "women and children first," became the standard on all British ships and it's exactly what
happened on the Titanic. The ship's crew and many passengers realized that they would not be saved,  14  
they did not panic. They helped others or 15 calmly for the icy death they knew was inevitable. In the movie, we see the ship's musicians playing to help  16  the passengers. We see the ship's officers keeping order as
the lifeboats are loaded. And we see British gentlemen "keeping their heads" as all about them are losing
theirs.
     No one knows how they will react in the face of a disaster. It all 17 one's character. Remarkably, most
people behave well. We have seen this in America's 911, in the 2008 Sichuan   18  and in Japan last
year.    19  such as the Titanic will happen, but the character of good people is   20  .
