英语课上的趣事

今天的第四节课是英语课，我们班又多了一位客人，就是飞蛾。飞蛾进到屋子里，有些同学就一直看着飞蛾，英语老师非常恼火，一怒之下说了这些同学。真是天不助师也，一只蜻蜓又飞到班里，一过天又帮助老师了，一会儿蜻蜓又不见了，教室里一下子安静了。

Today's fourth class is English. There is another guest in our class, the moth. When the moth came into the room, some of the students looked at it all the time. The English teacher was very angry and said to these students in a rage. It's really hard to help the teacher. A dragonfly flew to the class again. One day it helped the teacher again. After a while, the dragonfly disappeared and the classroom was quiet.

这节课真是潮起潮落。

This class is really up and down.
