Listen carefully and finish homework on time. If you don't come to the laboratory for class, do not do homework, and have a record of "learning through" on the network platform, there will be no results in this course. 认真听讲,按时完成作业。 如果你不来实验室上课,不做作业,在网络平台上有“通过学习”的记录,这门课就没有成绩。 Are you sure you know? 你确定你知道吗 ?
