I’ll never forget May 12, 2008, we were having classes at Beichuan Middle School , Sichuan Province, when a huge  36  hit the area.
At about 2:28 p.m, our  37  , Mr.Wang, was teaching us singing on the fourth floor on the teaching building.  38   we felt the building shaking violently. It was an earthquake! Our building starting to  39  . It was too late to rush out to the  40  . We were told to hide under the desks.  41  later, the whole building fell down. We were  42  in ruins. We couldn’t move at all. No one could really imagine at that split second, how much pain we had  43 or how desperate(绝望的) we felt as we waited to be  44 . I heard Mr. Wang calling our names again and again… .
Hours later, some people came to rescue and  45 of us were saved.
Later, I  46 this huge earthquake scaled 8.0 magnitude. It hit several provinces, including Sichuan, Gansu and Shanxi. So far it has  47 more than 80,000 and injured 360,000. My hometown ----Beichuan was  48  the worst-hit areas. Our school , which was  49  filled with vigor(活力) and laughter, was a dead valley.
Words after such a  50 could appear nothing but empty and pointless. So many people’s lives were taken away, so much  51  was done and the whole city was  52  . Beichuan has become a history.
Now , some of my classmates and I were  53  to study in a middle school in Jiangsu Province. I still  54  dreaming and still strive for a better future: to make our homes beautiful yet  55  .
May victims rest in peace. May survivors live to be stronger.
