Yesterday afternoon, when I was sitting in the classroom and listening to the teacher. Suddenly, the screen seemed moving and it started to shake. My teacher stopped his class and then he asked us to calm down. He let the students who were close to the door left first, and then the rest of us ran out of the classroom one by one. After a while, everything seemed to be normal, the teacher asked us to go back to the classroom. Later I learned that there indeed came the earthquake. I admired our teacher so much, in the important moment, he did not run away, but considered us in the first place. He is a good teacher. 
昨天下午，当我坐在教室里听老师讲课的时候。突然，屏幕似乎动了一下，之后就开始摇晃。老师暂停了课堂，并让我们冷静下来。他让靠近门口的学生先离开，然后再我们其余的人一个接一个地跑出了教室。过了一会，一切似乎恢复了正常，老师就让我们再回到教室。后来我才知道，其实刚才是发生了地震。我很佩服我们老师，在这么重要的时刻没有逃跑，而是把我们放在第一位。他是一个好老师。
