Explanation:
First, to prevent and control the epidemic, it is necessary to arrange the start of school according to the age and actual characteristics of students.
Young students are difficult to manage. On one occasion, a cartoon suggested to parents that children go out to kindergarten with white masks, but go home with blue masks. It turned out that the child was naughty and somehow exchanged his mask with other students, thinking it was fun, but he didn't realize the danger. This is a difficult point for young students to prevent and control the epidemic.
Therefore, instead of letting younger students start school first, it is better to let older students start school first. After all, they are more aware of safety and self-defense.
Second, graduating students will face the final exam, which is limited by the review time. In order to alleviate the anxiety of teachers and students' parents, senior students have to start school first.
Third, Beijing has a vast territory, frequent personnel exchanges at home and abroad, a very large flow of people and complicated traffic conditions, making it difficult to carry out prevention and control work.
Moreover, experts say that autumn and winter will come soon after the dog days. Autumn and winter have a low temperature climate, which is likely to make COVID-19 rebound again. In order to prevent external input and internal rebound, senior students with self-protection consciousness can start school first, which can give young students a transition period.
If COVID-19 really rebounds in autumn and winter, students with self-protection awareness will also alert us and ask the Ministry of Education and National Health Commission to make further prevention and control adjustments.
But with this year's disaster, I believe that even if there is a rebound, there will be no large-scale rebound. As long as we always keep our awareness of self-protection, do a good job of publicity, pay attention to hygiene and wear masks in crowded places, we can prevent this epidemic from spreading on a large scale.
