优点：上课认真听讲,积极发言,思路能跟着老师走,不说闲话； Advantages: class listen carefully, and actively speak, ideas can follow the teacher to go, do not say gossip; 缺点：人的注意力集中的时间有限,偶尔会思想抛锚（但是不会影响到听课效果）. Disadvantages: People's attention focused on the limited time, and occasionally break down (but not affect the effect of Lectures). 其实这个应该比较好写吧,自己总结一下平常课堂上的优点和缺点.老师让你们写这个是想让你们自我反省,总结得失,进而在课堂表现上有所改进. In fact, this should be quite good to write it, to sum up the advantages and disadvantages of the usual class. The teacher let you write this is to let you reflect on the gains and losses, and then in the classroom performance has improved.
