问题描述：
good stress might show up when you are called on in class .意思
Good stress might show up when you’re called on in class or when you have to give a report.You may do a better job in your book report if the anxiety (焦虑) pushes you to do more work before you read it to the class.请翻译，
答
你在课堂上被点名回答问题或者做报告时感到有压力未必是坏事,因为一定程度的压力有可能迫使你在之前做更充分的准备,从而有更好的表现.
供参考before you read it to the class.请翻译，多谢啦考虑到前半句刚刚提到“做报告”，所以为了避免拖沓，直接只译了“之前”。既然译成一个整句，语境都很熟悉，所以没有必要重复。
