昨天，老师告诉我们要在操场上进行了安全疏散演练。大家觉得特别紧张似的，有的人紧张的`都闭上了眼睛。一开始我不知道什么是安全疏散演练，我想警察叔叔肯定在操场上生了一小堆火，然后等同学们都来到操场上后，他们就把火扑灭了。结果到了操场上他们没有这样准备。
Yesterday, the teacher told us to have a safe evacuation drill in the playground. Everyone felt very nervous. Some people closed their eyes. At the beginning, I didn't know what the safe evacuation drill was. I think the police uncle must have made a small fire in the playground. Then when the students came to the playground, they put out the fire. As a result, they didn't prepare for it on the playground.
我们排着队一路小跑着来到操场，我看见主席台上站着刘校长。
We trotted all the way to the playground in line. I saw principal Liu standing on the rostrum.
还有王老师，刘校长告诉我们要注意安全，如果发生灾难的时候。就按照告诉我们的路线逃生，保护好自己的安全。
And Mr. Wang, principal Liu told us to pay attention to safety if there was a disaster. Just follow the route told us to escape and protect our own safety.
昨天的安全疏散演练结束了，我想以后不管什么时候，都得注意自己的安全。
Yesterday's safety evacuation drill is over. I think we should pay attention to our safety no matter when.
