1.地震开始时我正在图书馆里；
2.地面开始猛烈地摇晃；我试图往外跑，但玻璃碎片和砖头砸了下来，墙开始坍塌；最后，响声和摇动都停了下来；
3. 我意识到自己的一条腿被卡住了；我担心没人会发现我；所以尖声呼救；好在一条狗发现了我，有人把我拉了出去。
I was in the library when the earthquake started. The earth started to shake hard. I tried to run outside, but pieces of glass and bricks fell down, and the walls began to come down. Finally, the noise and shaking ended. I realized my leg was trapped. I was afraid that no one would find me. I screamed for help. Luckily, a dog found me and someone pulled me out.
