小小的教训

星期三下午在课外活动的时候，我们班有两个同学玩单杠。他们的手没有抓好单杠，一不小心掉了下来，把头摔破了，他们三天没有来上学，我们班的同学都去医院看望了他们，他们惭愧的低下了头，不好意思的说，以后我们在玩单杠的时候一定要小心。

On Wednesday afternoon, during the extracurricular activities, two students in our class played the horizontal bar. Their hands didn't grasp the horizontal bar well. They fell down accidentally and broke their heads. They didn't come to school for three days. All the students in our class went to the hospital to see them. They bowed their heads in shame. They were embarrassed to say that we must be careful when we play the horizontal bar in the future.
