Due to the epidemic and relevant regulations of school，we adopt online courses and this is a challenge for us.We must have good planning and organization in order to maintain the quality of critique avoid the limitations of time and space.For the purpose of going well，all students should hand in their works to the given cloud web site on the previous day.On the day of initial critique，four senior teachers came to school to proceed the critique and discussion，students stayed at home and presented online. We arranged one student came to school to assist and demonstrate the PowerPoint.Teachers brought their laptops to hold the Teams conference and control the speaker，in order to sound clearer and see the projection screen，they connected the audio system and projection screen.

At the beginning the equipment preparation wasted 10 minutes，after that everything is going well except some students didn’t control the time of presentation as planned，it is a pity that some works didn’t show completely. All critiques have time limits，students should practice in advance and present the main point during the limited time.

After a long day of critique，all teachers were exhausted because they concentrated on the presentation and gave advises to students.Students not only can get their own proposal but also can learn something from others, this is a valuable wealth of knowledge. At the end of the critique，students and teachers took a group photo online，put an end to the initial critique.
