四级作文（一）对网课的看法
参考范文：
Online learning has become an option because it provides flexible learning opportunities. This method has ensured that students do not get left behind on their academic study, however, some problems have also emerged during the course.
Since online learning lacks interaction compared with face-to-face teaching, it requires more attention and concentration. Sometimes, students find it so demanding to keep concentrated, and finally turn to some irrelevant online resources instead of academic study. To make sure that they stay tuned, some monitoring software can be ordered to download to ensure they are not browsing other websites while taking online courses. The increasing time students spending in digital devices also pose problems to their health. Thus, schools should encourage their students to do regular exercises such as stretches and eye massages during the break, and some guiding handbooks can be a good start.
The advance of technology should not come with the cost of loosing its original purpose, so does remote study. So we should do our utmost in doing away its possible detriments to the young.
