上课铃响了，学生络绎不绝地走进教室。无意间，我发现一个奇怪的现象：我们班大部分的男生走进教室的时候都把手插在裤袋里，摆出一副小帅哥的样子，这是怎么回事？下课后，我留意了一下在操场上玩耍的学生，只有我们班的学生有手插裤袋的习惯。我把这一有趣的现象告诉同事， The class bell rang and the students entered the classroom. Inadvertently, I found a strange phenomenon: Most of the boys in our class put their hands in their pockets when they entered the classroom and put on a look of a handsome boy. What happened? After class, I noticed the students who were playing in the playground. Only the students in our class had the habit of trousers. I told this colleague about this interesting phenomenon.
