A Complaint Letter about Campus Network Service (150-200 words)
Dear Sir or Madam,
I am writing to express my concern about the poor network service on campus. For quite some time, the campus internet has been slow and unstable, which greatly affects our study and daily life.
Many students have experienced frequent disconnections and difficulty accessing online courses and resources. Sometimes, it is even impossible to submit assignments or attend important online meetings on time. This situation has caused much frustration and inconvenience for both students and teachers.
We understand the demand for internet is high, but we sincerely hope that the university can take measures to improve the network quality. Upgrading the equipment and expanding bandwidth might be effective solutions. In addition, timely maintenance and prompt response to network problems are also necessary.
I believe that a reliable campus network is essential for modern college life. We hope that our suggestions will be given serious consideration, so that everyone can enjoy better online learning experiences.
Yours sincerely,
Li Ming
尊敬的负责人：
我写这封信是为了表达对校园网络服务不佳的担忧。相当长一段时间内，校园网络一直缓慢且不稳定，这极大影响了我们的学习和日常生活。
许多同学经常遇到断线和难以访问网课资源的问题。有时甚至无法按时提交作业或参加重要的网络会议。这种情况给师生们带来了很多困扰和不便。
我们理解网络需求量大，但真诚希望学校能够采取措施，提高网络质量。升级设备、扩展带宽也许是有效的解决办法。此外，及时维护和迅速响应网络问题同样很有必要。
我相信，可靠的校园网络对现代大学生活至关重要。希望我们的建议能被认真考虑，让大家都能享受更好的网络学习体验。
此致
敬礼
